emergencies require prompt assessment and management to avoid vision or life-threatening sequelae. Some would require neuroimaging. Most commonly used are the CT and MRI of the Brain. They can be over-used when not indicated. Their yield remains dependent on multiple factors relating to the clinical scenario. Methods: A retrospective cross-sectional study was conducted by reviewing the electronic medical records of patients presenting to the Emergency Department (ED) with isolated neuro-ophthalmologic complaints. For each patient, data were collected on the clinical presentation, whether neuroimaging was performed (and which type), and the result of neuroimaging. Analysis of the performed neuroimaging was made, and its yield was determined. Results: A total of 211 patients were reviewed. The complaints or symptoms at presentation were: blurry vision, change in the visual field, transient vision loss, floaters, double vision, eye pain, eyelid droop, headache, dizziness and others such as nausea or vomiting. In the ED, a total of 126 neuroimaging procedures were performed. Ninety-four imagings (74.6%) were normal, while 32 (25.4%) had relevant abnormal findings. Only 2 symptoms were significant for abnormal imaging: blurry vision (p-value= 0.038) and visual field change (p-value= 0.014). While 4 physical exam findings had significant abnormal imaging: visual field defect (p-value= 0.016), abnormal pupil reactivity (p-value= 0.028), afferent pupillary defect (p-value= 0.018), and abnormal optic disc exam (p-value= 0.009). Conclusion: Risk indicators for abnormal neuroimaging in the setting of neuro-ophthalmological emergencies are blurred vision or changes in the visual field on history taking. While visual field irregularities, abnormal pupil reactivity with or without afferent pupillary defect, or abnormal optic discs, are risk factors related to physical testing. These findings, when present, should sway the ED physician towards neuroimaging but still individualizing each case is of utmost importance to prevent time-consuming, resource-draining, and sometimes unnecessary workup. In the end, it suggests a well-structured patient-centered algorithm to be followed by ED physicians. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergency%20department" title="emergency department">emergency department</a>, <a href="https://publications.waset.org/abstracts/search?q=neuro-ophthalmology" title=" neuro-ophthalmology"> neuro-ophthalmology</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroimaging" title=" neuroimaging"> neuroimaging</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20indicators" title=" risk indicators"> risk indicators</a> </p> <a href="https://publications.waset.org/abstracts/133967/the-yield-of-neuroimaging-in-patients-presenting-to-the-emergency-department-with-isolated-neuro-ophthalmological-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133967.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">179</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">72</span> Integrating Cyber-Physical System toward Advance Intelligent Industry: Features, Requirements and Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Reyes">V.

Ferreira </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In response to high levels of competitiveness, industrial systems have evolved to improve productivity. As a consequence, a rapid increase in volume production and simultaneously, a customization process require lower costs, more variety, and accurate quality of products. Reducing time-cycle production, enabling customizability, and ensure continuous quality improvement are key features in advance intelligent industry. In this scenario, customers and producers will be able to participate in the ongoing production life cycle through real-time interaction. To achieve this vision, transparency, predictability, and adaptability are key features that provide the industrial systems the capability to adapt to customer demands modifying the manufacturing process through an autonomous response and acting preventively to avoid errors. The industrial system incorporates a diversified number of components that in advanced industry are expected to be decentralized, end to end communicating, and with the capability to make own decisions through feedback. The evolving process towards advanced intelligent industry defines a set of stages to empower components of intelligence and enhancing efficiency to achieve the decision-making stage. The integrated system follows an industrial cyber-physical system (CPS) architecture whose real-time integration, based on a set of enabler technologies, links the physical and virtual world generating the digital twin (DT). This instance allows incorporating sensor data from real to virtual world and the required transparency for real-time monitoring and control, contributing to address important features of the advanced intelligent industry and simultaneously improve sustainability. Assuming the industrial CPS as the core technology toward the latest advanced intelligent industry stage, this paper reviews and highlights the correlation and contributions of the enabler technologies for the operationalization of each stage in the path toward advanced intelligent industry. From this research, a real-time integration architecture for a cyber-physical system with applications to collaborative robotics is proposed. The required functionalities and issues to endow the industrial system of adaptability are identified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyber-physical%20systems" title="cyber-physical systems">cyber-physical systems</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20twin" title=" digital twin"> digital twin</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20data" title=" sensor data"> sensor data</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20integration" title=" system integration"> system integration</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20model" title=" virtual model"> virtual model</a> </p> <a href="https://publications.waset.org/abstracts/114027/integrating-cyber-physical-system-toward-advance-intelligent-industry-features-requirements-and-challenges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114027.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">118</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">71</span> Standardizing and Achieving Protocol Objectives for ChestWall Radiotherapy Treatment Planning Process using an O-ring Linac in High-, Low- and Middle-income Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milton%20Ixquiac">Milton Ixquiac</a>, <a href="https://publications.waset.org/abstracts/search?q=Erick%20Montenegro"> Erick Montenegro</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Reynoso"> Francisco Reynoso</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Schmidt"> Matthew Schmidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Mazur"> Thomas Mazur</a>, <a href="https://publications.waset.org/abstracts/search?q=Tianyu%20Zhao"> Tianyu Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiram%20Gay"> Hiram Gay</a>, <a href="https://publications.waset.org/abstracts/search?q=Geoffrey%20Hugo"> Geoffrey Hugo</a>, <a href="https://publications.waset.org/abstracts/search?q=Lauren%20Henke"> Lauren Henke</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Michael%20Michalski"> Jeff Michael Michalski</a>, <a href="https://publications.waset.org/abstracts/search?q=Angel%20Velarde"> Angel Velarde</a>, <a href="https://publications.waset.org/abstracts/search?q=Vicky%20de%20Falla"> Vicky de Falla</a>, <a href="https://publications.waset.org/abstracts/search?q=Franky%20Reyes"> Franky Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Osmar%20Hernandez"> Osmar Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Aparicio%20Ruiz"> Edgar Aparicio Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Baozhou%20Sun"> Baozhou Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Radiotherapy departments in low- and middle-income countries (LMICs) like Guatemala have recently introduced intensity-modulated radiotherapy (IMRT). IMRT has become the standard of care in high-income countries (HIC) due to reduced toxicity and improved outcomes in some cancers. The purpose of this work is to show the agreement between the dosimetric results shown in the Dose Volume Histograms (DVH) to the objectives proposed in the adopted protocol. This is the initial experience with an O-ring Linac. Methods and Materials: An O-Linac Linac was installed at our clinic in Guatemala in 2019 and has been used to treat approximately 90 patients daily with IMRT. This Linac is a completely Image Guided Device since to deliver each radiotherapy session must take a Mega Voltage Cone Beam Computerized Tomography (MVCBCT). In each MVCBCT, the Linac deliver 9 UM, and they are taken into account while performing the planning. To start the standardization, the TG263 was employed in the nomenclature and adopted a hypofractionated protocol to treat ChestWall, including supraclavicular nodes achieving 40.05Gy in 15 fractions. The planning was developed using 4 semiarcs from 179-305 degrees. The planner must create optimization volumes for targets and Organs at Risk (OARs); the difficulty for the planner was the dose base due to the MVCBCT. To evaluate the planning modality, we used 30 chestwall cases. Results: The plans created manually achieve the protocol objectives. The protocol objectives are the same as the RTOG1005, and the DHV curves look clinically acceptable. Conclusions: Despite the O-ring Linac doesn´t have the capacity to obtain kv images, the cone beam CT was created using MV energy, the dose delivered by the daily image setup process still without affect the dosimetric quality of the plans, and the dose distribution is acceptable achieving the protocol objectives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypofrationation" title="hypofrationation">hypofrationation</a>, <a href="https://publications.waset.org/abstracts/search?q=VMAT" title=" VMAT"> VMAT</a>, <a href="https://publications.waset.org/abstracts/search?q=chestwall" title=" chestwall"> chestwall</a>, <a href="https://publications.waset.org/abstracts/search?q=radiotherapy%20planning" title=" radiotherapy planning"> radiotherapy planning</a> </p> <a href="https://publications.waset.org/abstracts/163550/standardizing-and-achieving-protocol-objectives-for-chestwall-radiotherapy-treatment-planning-process-using-an-o-ring-linac-in-high-low-and-middle-income-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163550.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">118</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">70</span> Composite Materials from Beer Bran Fibers and Polylactic Acid: Characterization and Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Camila%20Hurtado">Camila Hurtado</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20A.%20Morales"> Maria A.

Treated and untreated fibers were physically characterized in terms of their moisture content (ASTM D1348), density, and particle size (ASAE S319.2). A chemical analysis following TAPPI standards was performed to determine ash, extractives, lignin, and cellulose content on fibers. Thermal stability was determined by TGA analysis, and an FTIR was carried out to check the influence of the alkali treatment in fiber composition. An alkali treatment with NaOH (5%) of fibers was performed for 90 min, with the objective to improve the interfacial adhesion with polymeric matrix in composites. Composite materials based on either treated or untreated beer brand fibers and polylactic acid (PLA) were developed characterized in tension (ASTM D638), bending (ASTM D790) and impact (ASTM D256). Before composites manufacturing, PLA and brand beer fibers (10 wt.%) were mixed in a twin extruder with a temperature profile between 155°C and 180°C. Coupons were manufactured by compression molding (110 bar) at 190°C. Physical characterization showed that alkali treatment does not affect the moisture content (6.9%) and the density (0.48 g/cm³ for untreated fiber and 0.46 g/cm³ for the treated one). Chemical and FTIR analysis showed a slight decrease in ash and extractives. Also, a decrease of 47% and 50% for lignin and hemicellulose content was observed, coupled with an increase of 71% for cellulose content. Fiber thermal stability was improved with the alkali treatment at about 10°C. Tensile strength of composites was found to be between 42 and 44 MPa with no significant statistical difference between coupons with either treated or untreated fibers. However, compared to neat PLA, composites with beer bran fibers present a decrease in tensile strength of 27%. Young modulus increases by 10% with treated fiber, compared to neat PLA. Flexural strength decreases in coupons with treated fiber (67.7 MPa), while flexural modulus increases (3.2 GPa) compared to neat PLA (83.3 MPa and 2.8 GPa, respectively). Izod impact test results showed an improvement of 99.4% in coupons with treated fibers - compared with neat PLA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beer%20bran" title="beer bran">beer bran</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20composite" title=" green composite"> green composite</a>, <a href="https://publications.waset.org/abstracts/search?q=polylactic%20acid" title=" polylactic acid"> polylactic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20treatment" title=" surface treatment"> surface treatment</a> </p> <a href="https://publications.waset.org/abstracts/134876/composite-materials-from-beer-bran-fibers-and-polylactic-acid-characterization-and-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134876.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">69</span> Community Observatory for Territorial Information Control and Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Olivi">A.

Reyes Cabrera</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ageing and urbanization are two of the main trends that characterize the twenty-first century. Its trending is especially accelerated in the emerging countries of Asia and Latin America. Chile is one of the countries in the Latin American region, where the demographic transition to ageing is becoming increasingly visible. The challenges that the new demographic scenario poses to urban administrators call for searching innovative solutions to maximize the functional and psycho-social benefits derived from the relationship between older people and the environment in which they live. Although mobility is central to people's everyday practices and social relationships, it is not distributed equitably. On the contrary, it can be considered another factor of inequality in our cities. Older people are a particularly sensitive and vulnerable group to mobility. In this context, based on the ageing in place strategy and following the social innovation approach within a spatial context, the "Community Observatory of Territorial Information Control and Management" project aims at the collective search and validation of solutions for the satisfaction of mobility and accessibility specific needs of urban aged people. Specifically, the Observatory intends to: i) promote the direct participation of the aged population in order to generate relevant information on the territorial situation and the satisfaction of the mobility needs of this group; ii) co-create dynamic and efficient mechanisms for the reporting and updating of territorial information; iii) increase the capacity of the local administration to plan and manage solutions to environmental problems at the neighborhood scale. Based on a participatory mapping methodology and on the application of digital technology, the Observatory designed and developed, together with aged people, a crowdsourcing platform for smartphones, called DIMEapp, for reporting environmental problems affecting mobility and accessibility. DIMEapp has been tested at a prototype level in two neighborhoods of the city of Valparaiso. The results achieved in the testing phase have shown high potential in order to i) contribute to establishing coordination mechanisms with the local government and the local community; ii) improve a local governance system that guides and regulates the allocation of goods and services destined to solve those problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessibility" title="accessibility">accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=ageing" title=" ageing"> ageing</a>, <a href="https://publications.waset.org/abstracts/search?q=city" title=" city"> city</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20technology" title=" digital technology"> digital technology</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20governance" title=" local governance"> local governance</a> </p> <a href="https://publications.waset.org/abstracts/115816/community-observatory-for-territorial-information-control-and-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115816.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">68</span> Soil Quality Response to Long-Term Intensive Resources Management and Soil Texture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalia%20Feiziene">Dalia Feiziene</a>, <a href="https://publications.waset.org/abstracts/search?q=Virginijus%20Feiza"> Virginijus Feiza</a>, <a href="https://publications.waset.org/abstracts/search?q=Agne%20Putramentaite"> Agne Putramentaite</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Volungevicius"> Jonas Volungevicius</a>, <a href="https://publications.waset.org/abstracts/search?q=Kristina%20Amaleviciute"> Kristina Amaleviciute</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarunas%20Antanaitis"> Sarunas Antanaitis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The investigations on soil conservation are one of the most important topics in modern agronomy. Soil management practices have great influence on soil physico-chemical quality and GHG emission. Research objective: To reveal the sensitivity and vitality of soils with different texture to long-term antropogenisation on Cambisol in Central Lithuania and to compare them with not antropogenised soil resources. Methods: Two long-term field experiments (loam on loam; sandy loam on loam) with different management intensity were estimated. Disturbed and undisturbed soil samples were collected from 5-10, 15-20 and 30-35 cm depths. Soil available P and K contents were determined by ammonium lactate extraction, total N by the dry combustion method, SOC content by Tyurin titrimetric (classical) method, texture by pipette method. In undisturbed core samples soil pore volume distribution, plant available water (PAW) content were determined. A closed chamber method was applied to quantify soil respiration (SR). Results: Long-term resources management changed soil quality. In soil with loam texture, within 0-10, 10-20 and 30-35 cm soil layers, significantly higher PAW, SOC and mesoporosity (MsP) were under no-tillage (NT) than under conventional tillage (CT). However, total porosity (TP) under NT was significantly higher only in 0-10 cm layer. MsP acted as dominant factor for N, P and K accumulation in adequate layers. P content in all soil layers was higher under NT than in CT. N and K contents were significantly higher than under CT only in 0-10 cm layer. In soil with sandy loam texture, significant increase in SOC, PAW, MsP, N, P and K under NT was only in 0-10 cm layer. TP under NT was significantly lower in all layers. PAW acted as strong dominant factor for N, P, K accumulation. The higher PAW the higher NPK contents were determined. NT did not secure chemical quality within deeper layers than CT. Long-term application of mineral fertilisers significantly increased SOC and soil NPK contents primarily in top-soil. Enlarged fertilization determined the significantly higher leaching of nutrients to deeper soil layers (CT) and increased hazards of top-soil pollution. Straw returning significantly increased SOC and NPK accumulation in top-soil. The SR on sandy loam was significantly higher than on loam. At dry weather conditions, on loam SR was higher in NT than in CT, on sandy loam SR was higher in CT than in NT. NPK fertilizers promoted significantly higher SR in both dry and wet year, but suppressed SR on sandy loam during usual year. Not antropogenised soil had similar SOC and NPK distribution within 0-35 cm layer and depended on genesis of soil profile horizons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fertilizers" title="fertilizers">fertilizers</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20experiments" title=" long-term experiments"> long-term experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20texture" title=" soil texture"> soil texture</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20tillage" title=" soil tillage"> soil tillage</a>, <a href="https://publications.waset.org/abstracts/search?q=straw" title=" straw"> straw</a> </p> <a href="https://publications.waset.org/abstracts/52991/soil-quality-response-to-long-term-intensive-resources-management-and-soil-texture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52991.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> The Composition and Activity of Germinated Broccoli Seeds and Their Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boris%20Nemzer">Boris Nemzer</a>, <a href="https://publications.waset.org/abstracts/search?q=Tania%20Reyes-Izquierdo"> Tania Reyes-Izquierdo</a>, <a href="https://publications.waset.org/abstracts/search?q=Zbigniew%20Pietrzkowski"> Zbigniew Pietrzkowski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Glucosinolate is a family of glucosides that can be found in a family of brassica vegetables. Upon the damage of the plant, glucosinolate breakdown by an internal enzyme myrosinase (thioglucosidase; EC 3.2.3.1) into isothiocyanates, such as sulforaphane. Sulforaphane is formed by glucoraphanin cleaving the sugar off by myrosinase and rearranged. Sulforaphane nitrile is formed in the same reaction as sulforaphane with the active of epithiospecifier protein (ESP). Most common food processing procedure would break the plant and mix the glucoraphanin and myrosinase together, and the formed sulforaphane would be further degraded. The purpose of this study is to understand the glucoraphanin/sulforaphane and the myrosinase activity of broccoli seeds germinated at a different time and technological processing conditions that keep the activity of the enzyme to form sulforaphane. Broccoli seeds were germinated in the house. Myrosinase activities were tested as the glucose content using glucose assay kit and measured UV-Vis spectrophotometer. Glucosinolates were measured by HPLC/DAD. Sulforaphane was measured using HPLC-DAD and GC/MS. The 6 hr germinated sprouts have a myrosinase activity 32.2 mg glucose/g, which is comparable with 12 and 24 hour germinated seeds and higher than dry seeds. The glucoraphanin content in 6 hour germinated sprouts is 13935 µg/g which is comparable to 24 hour germinated seeds and lower than the dry seeds. GC/MS results show that the amount of sulforaphane is higher than the amount of sulforaphane nitrile in seeds, 6 hour and 24 hour germinated seeds. The ratio of sulforaphane and sulforaphane nitrile is high in 6 hour germinated seeds, which indicates the inactivated ESP in the reaction. After evaluating the results, the short time germinated seeds can be used as the source of glucoraphanin and myrosinase supply to form potential higher sulforaphane content. Broccoli contains glucosinolates, glucoraphanin (4-methylsulfinylbutyl glucosinolate), which is an important metabolite with health-promoting effects. In the pilot clinical study, we observed the effects of a glucosinolates/glucoraphanin-rich extract from short time germinated broccoli seeds on blood adenosine triphosphate (ATP), reactive oxygen species (ROS) and lactate levels. A single dose of 50 mg of broccoli sprouts extract increased blood levels of ATP up to 61% (p=0.0092) during the first 2 hours after the ingestion. Interestingly, this effect was not associated with an increase in blood ROS or lactate. When compared to the placebo group, levels of lactate were reduced by 10% (p=0.006). These results indicate that broccoli germinated seed extract may positively affect the generation of ATP in humans. Due to the preliminary nature of this work and promising results, larger clinical trials are justified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broccoli%20glucosinolates" title="broccoli glucosinolates">broccoli glucosinolates</a>, <a href="https://publications.waset.org/abstracts/search?q=glucoraphanin" title=" glucoraphanin"> glucoraphanin</a>, <a href="https://publications.waset.org/abstracts/search?q=germinated%20seeds" title=" germinated seeds"> germinated seeds</a>, <a href="https://publications.waset.org/abstracts/search?q=myrosinase" title=" myrosinase"> myrosinase</a>, <a href="https://publications.waset.org/abstracts/search?q=adenosine%20triphosphate" title=" adenosine triphosphate"> adenosine triphosphate</a> </p> <a href="https://publications.waset.org/abstracts/63425/the-composition-and-activity-of-germinated-broccoli-seeds-and-their-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63425.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> [Keynote Talk]: Knowledge Codification and Innovation Success within Digital Platforms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wissal%20Ben%20Arfi">Wissal Ben Arfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lubica%20Hikkerova"> Lubica Hikkerova</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Michel%20Sahut"> Jean-Michel Sahut</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines interfirm networks in the digital transformation era, and in particular, how tacit knowledge codification affects innovation success within digital platforms. Hence, one of the most important features of digital transformation and innovation process outcomes is the emergence of digital platforms, as an interfirm network, at the heart of open innovation. This research aims to illuminate how digital platforms influence inter-organizational innovation through virtual team interactions and knowledge sharing practices within an interfirm network. Consequently, it contributes to the respective strategic management literature on new product development (NPD), open innovation, industrial management, and its emerging interfirm networks’ management. The empirical findings show, on the one hand, that knowledge conversion may be enhanced, especially by the socialization which seems to be the most important phase as it has played a crucial role to hold the virtual team members together. On the other hand, in the process of socialization, the tacit knowledge codification is crucial because it provides the structure needed for the interfirm network actors to interact and act to reach common goals which favor the emergence of open innovation. Finally, our results offer several conditions necessary, but not always sufficient, for interfirm managers involved in NPD and innovation concerning strategies to increasingly shape interconnected and borderless markets and business collaborations. In the digital transformation era, the need for adaptive and innovative business models as well as new and flexible network forms is becoming more significant than ever. Supported by technological advancements and digital platforms, companies could benefit from increased market opportunities and creating new markets for their innovations through alliances and collaborative strategies, as a mode of reducing or eliminating uncertainty environments or entry barriers. Consequently, an efficient and well-structured interfirm network is essential to create network capabilities, to ensure tacit knowledge sharing, to enhance organizational learning and to foster open innovation success within digital platforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interfirm%20networks" title="interfirm networks">interfirm networks</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20platform" title=" digital platform"> digital platform</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20teams" title=" virtual teams"> virtual teams</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20innovation" title=" open innovation"> open innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20sharing" title=" knowledge sharing"> knowledge sharing</a> </p> <a href="https://publications.waset.org/abstracts/114296/keynote-talk-knowledge-codification-and-innovation-success-within-digital-platforms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114296.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Developing Family-Based Eco-Citizenship with Social Media: A Mixed Methods Collective Case Study of Families Looking to Adopt Ecologically Responsible Actions Using Facebook</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michel%20T.%20Leger">Michel T.

Though research in environmental education does point to an increase in the intention to act more responsibly towards the environment, this intent does not seem to translate to concrete ecological action. This mixed methods collective case study explores the adoption of ecological actions in the family, a context of socio-ecological transformation rarely examined in the scientific literature. More specifically, it takes into account the popular use of social media today to explore the potential role social media, namely Facebook, in promoting environmental action. In other words, for families who are intent on adopting an ecologically friendly lifestyle, could the use of Facebook positively affect the way family members relate to the environment and bring about real change in their daily household actions? To answer this question, twenty-one families living in an urban setting were recruited and then divided them into two distinct groups. The first group of families attempted to lower their household electrical bill as part of a private Facebook group, while the other aimed to do the same, but without the directed use of social media. For both groups, we recorded the amount of kilowatt-hours used during the project as well as the amount used for the same months the previous year, adjusting for temperature variations. Exit interviews were also conducted with each family in order to try to understand the processes of eco-citizenship development in the context of family. Results seem to suggest that both virtual social networks and one-on-one support can help to increase environmental awareness in participating family. Interestingly, families from the Facebook group seemed to demonstrate a higher degree of environmental engagement, and younger family members in this group were more active in the processes of collective behavioral change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20education" title="environmental education">environmental education</a>, <a href="https://publications.waset.org/abstracts/search?q=family-based%20eco-citizenship" title=" family-based eco-citizenship"> family-based eco-citizenship</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20study" title=" case study"> case study</a> </p> <a href="https://publications.waset.org/abstracts/87398/developing-family-based-eco-citizenship-with-social-media-a-mixed-methods-collective-case-study-of-families-looking-to-adopt-ecologically-responsible-actions-using-facebook" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87398.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">64</span> The Correlation between Emotional Intelligence and Locus of Control: Empirical Study on Lithuanian Youth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalia%20Antiniene">Dalia Antiniene</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosita%20Lekaviciene"> Rosita Lekaviciene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The qualitative methodology based study is designed to reveal a connection between emotional intelligence (EI) and locus of control (LC) within the population of Lithuanian youth. In the context of emotional problems, the locus of control reflects how one estimates the causes of his/her emotions: internals (internal locus of control) associate their emotions with their manner of thinking, whereas externals (external locus of control) consider emotions to be evoked by external circumstances. On the other hand, there is little empirical data about this connection, and the results in disposition are often contradictory. In the conducted study 1430 young people, aged 17 to 27, from various regions of Lithuania were surveyed. The subjects were selected by quota sampling, maintaining natural proportions of the general Lithuanian youth population. To assess emotional intelligence the EI-DARL test (i.e. self-report questionnaire consisting of 75 items) was implemented. The emotional intelligence test, created applying exploratory factor analysis, reveals four main dimensions of EI: understanding of one’s own emotions, regulation of one’s own emotions, understanding other’s emotions, and regulation of other’s emotions (subscale reliability coefficients fluctuate between 0,84 and 0,91). An original 16-item internality/externality scale was used to examine the locus of control (internal consistency of the Externality subscale - 0,75; Internality subscale - 0,65). The study has determined that the youth understands and regulates other people’s emotions better than their own. Using the K-mean cluster analysis method, it was established that there are three groups of subjects according to their EI level – people with low, medium and high EI. After comparing means of subjects’ favorability of statements on the Internality/Externality scale, a predominance of internal locus of control in the young population was established. The multiple regression models has shown that a rather strong statistically significant correlation exists between total EI, EI subscales and LC. People who tend to attribute responsibility for the outcome of their actions to their own abilities and efforts have higher EI and, conversely, the tendency to attribute responsibility to external forces is related more with lower EI. While pursuing their goals, young people with high internality have a predisposition to analyze perceived emotions and, therefore, gain emotional experience: they learn to control their natural reactions and to act adequately in a situation at hand. Thus the study unfolds, that a person’s locus of control and emotional intelligence are related phenomena and allows us to draw a conclusion, that a person’s internality/externality is a reliable predictor of total EI and its components. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence" title="emotional intelligence">emotional intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=externality" title=" externality"> externality</a>, <a href="https://publications.waset.org/abstracts/search?q=internality" title=" internality"> internality</a>, <a href="https://publications.waset.org/abstracts/search?q=locus%20of%20control" title=" locus of control"> locus of control</a> </p> <a href="https://publications.waset.org/abstracts/72486/the-correlation-between-emotional-intelligence-and-locus-of-control-empirical-study-on-lithuanian-youth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72486.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Effect of Cognitive Rehabilitation in Pediatric Population with Acquired Brain Injury: A Pilot Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Beltran">Carolina Beltran</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20De%20Los%20Reyes"> Carlos De Los Reyes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acquired brain injury (ABI) is any physical and functional injury secondary to events that affect the brain tissue. It is one of the biggest causes of disability in the world and it has a high annual incidence in the pediatric population. There are several causes of ABI such as traumatic brain injury, central nervous system infection, stroke, hypoxia, tumors and others. The consequences can be cognitive, behavioral, emotional and functional. The cognitive rehabilitation is necessary to achieve the best outcomes for pediatric people with ABI. Cognitive orientation to daily occupational performance (CO-OP) is an individualized client-centered, performance-based, problem-solving approach that focuses on the strategy used to support the acquisition of three client-chosen goals. It has demonstrated improvements in the pediatric population with other neurological disorder but not in Spanish speakers with ABI. Aim: The main objective of this study was to determine the efficacy of cognitive orientation to daily occupational performances (CO-OP) adapted to Spanish speakers, in the level of independence and behavior in a pediatric population with ABI. Methods: Case studies with measure pre/post-treatment were used in three children with ABI, sustained at least before 6 months assessment, in school, aged 8 to 16 years, age ABI after 6 years old and above average intellectual ability. Twelve sessions of CO-OP adapted to Spanish speakers were used and videotaped. The outcomes were based on cognitive, behavior and functional independence measurements such as Child Behavior Checklist (CBCL), Behavior Rating Inventory of Executive Function (BRIEF), The Vineland Adaptive Behavior Scales (VINELAND, Social Support Scale (MOS-SSS) and others neuropsychological measures. This study was approved by the ethics committee of Universidad del Norte in Colombia. Informed parental written consent was obtained for all participants. Results: children were able to identify three goals and use the global strategy ‘goal-plan-do-check’ during each session. Verbal self-instruction was used by all children. CO-OP showed a clinically significant improvement in goals regarding with independence level and behavior according to parents and teachers. Conclusion: The results indicated that CO-OP and the use of a global strategy such as ‘goal-plan-do-check’ can be used in children with ABI in order to improve their specific goals. This is a preliminary version of a big study carrying in Colombia as part of the experimental design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20rehabilitation" title="cognitive rehabilitation">cognitive rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=acquired%20brain%20injury" title=" acquired brain injury"> acquired brain injury</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric%20population" title=" pediatric population"> pediatric population</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20orientation%20to%20daily%20occupational%20performance" title=" cognitive orientation to daily occupational performance"> cognitive orientation to daily occupational performance</a> </p> <a href="https://publications.waset.org/abstracts/96389/effect-of-cognitive-rehabilitation-in-pediatric-population-with-acquired-brain-injury-a-pilot-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96389.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Self-Assembled Laser-Activated Plasmonic Substrates for High-Throughput, High-Efficiency Intracellular Delivery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marinna%20Madrid">Marinna Madrid</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabiha%20Saklayen"> Nabiha Saklayen</a>, <a href="https://publications.waset.org/abstracts/search?q=Marinus%20Huber"> Marinus Huber</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Vogel"> Nicolas Vogel</a>, <a href="https://publications.waset.org/abstracts/search?q=Christos%20Boutopoulos"> Christos Boutopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Meunier"> Michel Meunier</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Mazur"> Eric Mazur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Delivering material into cells is important for a diverse range of biological applications, including gene therapy, cellular engineering and imaging. We present a plasmonic substrate for delivering membrane-impermeable material into cells at high throughput and high efficiency while maintaining cell viability. The substrate fabrication is based on an affordable and fast colloidal self-assembly process. When illuminated with a femtosecond laser, the light interacts with the electrons at the surface of the metal substrate, creating localized surface plasmons that form bubbles via energy dissipation in the surrounding medium. These bubbles come into close contact with the cell membrane to form transient pores and enable entry of membrane-impermeable material via diffusion. We use fluorescence microscopy and flow cytometry to verify delivery of membrane-impermeable material into HeLa CCL-2 cells. We show delivery efficiency and cell viability data for a range of membrane-impermeable cargo, including dyes and biologically relevant material such as siRNA. We estimate the effective pore size by determining delivery efficiency for hard fluorescent spheres with diameters ranging from 20 nm to 2 um. To provide insight to the cell poration mechanism, we relate the poration data to pump-probe measurements of micro- and nano-bubble formation on the plasmonic substrate. Finally, we investigate substrate stability and reusability by using scanning electron microscopy (SEM) to inspect for damage on the substrate after laser treatment. SEM images show no visible damage. Our findings indicate that self-assembled plasmonic substrates are an affordable tool for high-throughput, high-efficiency delivery of material into mammalian cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=femtosecond%20laser" title="femtosecond laser">femtosecond laser</a>, <a href="https://publications.waset.org/abstracts/search?q=intracellular%20delivery" title=" intracellular delivery"> intracellular delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=plasmonic" title=" plasmonic"> plasmonic</a>, <a href="https://publications.waset.org/abstracts/search?q=self-assembly" title=" self-assembly"> self-assembly</a> </p> <a href="https://publications.waset.org/abstracts/33571/self-assembled-laser-activated-plasmonic-substrates-for-high-throughput-high-efficiency-intracellular-delivery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33571.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">529</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">61</span> Spatial Variability of Renieramycin-M Production in the Philippine Blue Sponge, Xestospongia Sp.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Geminne%20Manzano">Geminne Manzano</a>, <a href="https://publications.waset.org/abstracts/search?q=Porfirio%20Ali%C3%B1o"> Porfirio Aliño</a>, <a href="https://publications.waset.org/abstracts/search?q=Clairecynth%20Yu"> Clairecynth Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lilibeth%20Salvador-Reyes"> Lilibeth Salvador-Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Viviene%20Santiago"> Viviene Santiago</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many marine benthic organisms produce secondary metabolites that serve as ecological roles to different biological and environmental factors. The secondary metabolites found in these organisms like algae, sponges, tunicates and worms exhibit variation at different scales. Understanding the chemical variation can be essential in deriving the evolutionary and ecological function of the secondary metabolites that may explain their patterns. Ecological surveys were performed on two collection sites representing from two Philippine marine biogeographic regions – in Oriental Mindoro located on the West Philippine Sea (WPS) and in Zamboanga del Sur located at Celebes Sea (CS), where a total of 39 Xestospongia sp. sponges were collected using SCUBA. The sponge samples were transported to the laboratory for taxonomic identification and chemical analysis. Biological and environmental factors were investigated to determine their relation to the abundance and distribution patterns and its spatial variability of their secondary metabolite production. Extracts were subjected to thin-layer chromatography and anti-proliferative assays to confirm the presence of Renieramycin-M and to test its cytotoxicity. The blue sponges were found to be more abundant on the WPS than in CS. Both the benthic community and the fish community in Oriental Mindoro, WPS and Zamboanga del Sur, CS sites are characterized by high species diversity and abundance and a very high biomass category. Environmental factors like depth and monsoonal exposure were also compared showing that wave exposure and depth are associated with the abundance and distribution of the sponges. Renieramycin-M presence using the TLC profiles between the sponge extracts from WPS and from CS showed differences in the Reniermycin-M presence and the presence of other functional groups were observed between the two sites. In terms of bioactivity, different responses were also exhibited by the sponge extracts coming from the different region. Different responses were also noted on its bioactivity depending on the cell lines tested. Exploring the influence of ecological parameters on the chemical variation can provide deeper chemical ecological insights in the knowledge and their potential varied applications at different scales. The results of this study provide further impetus in pursuing studies into patterns and processes of the chemical diversity of the Philippine blue sponge, Xestospongia sp. and the chemical ecological significance of the coral triangle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20ecology" title="chemical ecology">chemical ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=porifera" title=" porifera"> porifera</a>, <a href="https://publications.waset.org/abstracts/search?q=renieramycin-m" title=" renieramycin-m"> renieramycin-m</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20variability" title=" spatial variability"> spatial variability</a>, <a href="https://publications.waset.org/abstracts/search?q=Xestospongia%20sp." title=" Xestospongia sp."> Xestospongia sp.</a> </p> <a href="https://publications.waset.org/abstracts/52655/spatial-variability-of-renieramycin-m-production-in-the-philippine-blue-sponge-xestospongia-sp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52655.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">210</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Optimizing Hydrogen Production from Biomass Pyro-Gasification in a Multi-Staged Fluidized Bed Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chetna%20Mohabeer">Chetna Mohabeer</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Reyes"> Luis Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Lokmane%20Abdelouahed"> Lokmane Abdelouahed</a>, <a href="https://publications.waset.org/abstracts/search?q=Bechara%20Taouk"> Bechara Taouk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the transition to sustainability and the increasing use of renewable energy, hydrogen will play a key role as an energy carrier. Biomass has the potential to accelerate the realization of hydrogen as a major fuel of the future. Pyro-gasification allows the conversion of organic matter mainly into synthesis gas, or “syngas”, majorly constituted by CO, H2, CH4, and CO2. A second, condensable fraction of biomass pyro-gasification products are “tars”. Under certain conditions, tars may decompose into hydrogen and other light hydrocarbons. These conditions include two types of cracking: homogeneous cracking, where tars decompose under the effect of temperature ( > 1000 °C), and heterogeneous cracking, where catalysts such as olivine, dolomite or biochar are used. The latter process favors cracking of tars at temperatures close to pyro-gasification temperatures (~ 850 °C). Pyro-gasification of biomass coupled with water-gas shift is the most widely practiced process route for biomass to hydrogen today. In this work, an innovating solution will be proposed for this conversion route, in that all the pyro-gasification products, not only methane, will undergo processes that aim to optimize hydrogen production. First, a heterogeneous cracking step was included in the reaction scheme, using biochar (remaining solid from the pyro-gasification reaction) as catalyst and CO2 and H2O as gasifying agents. This process was followed by a catalytic steam methane reforming (SMR) step. For this, a Ni-based catalyst was tested under different reaction conditions to optimize H2 yield. Finally, a water-gas shift (WGS) reaction step with a Fe-based catalyst was added to optimize the H2 yield from CO. The reactor used for cracking was a fluidized bed reactor, and the one used for SMR and WGS was a fixed bed reactor. The gaseous products were analyzed continuously using a µ-GC (Fusion PN 074-594-P1F). With biochar as bed material, it was seen that more H2 was obtained with steam as a gasifying agent (32 mol. % vs. 15 mol. % with CO2 at 900 °C). CO and CH4 productions were also higher with steam than with CO2. Steam as gasifying agent and biochar as bed material were hence deemed efficient parameters for the first step. Among all parameters tested, CH4 conversions approaching 100 % were obtained from SMR reactions using Ni/γ-Al2O3 as a catalyst, 800 °C, and a steam/methane ratio of 5. This gave rise to about 45 mol % H2. Experiments about WGS reaction are currently being conducted. At the end of this phase, the four reactions are performed consecutively, and the results analyzed. The final aim is the development of a global kinetic model of the whole system in a multi-stage fluidized bed reactor that can be transferred on ASPEN PlusTM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-staged%20fluidized%20bed%20reactor" title="multi-staged fluidized bed reactor">multi-staged fluidized bed reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=pyro-gasification" title=" pyro-gasification"> pyro-gasification</a>, <a href="https://publications.waset.org/abstracts/search?q=steam%20methane%20reforming" title=" steam methane reforming"> steam methane reforming</a>, <a href="https://publications.waset.org/abstracts/search?q=water-gas%20shift" title=" water-gas shift"> water-gas shift</a> </p> <a href="https://publications.waset.org/abstracts/125412/optimizing-hydrogen-production-from-biomass-pyro-gasification-in-a-multi-staged-fluidized-bed-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125412.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Q Eqchi Mayan Piper and Cissampelos Species Alter Reporter Genes and Endogenous Genes Expression in Mc-7 Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sheila%20M.%20Wicks">Sheila M.

During our ethno medical work in Guatemala of the 27 plant families documented for us e by the Qeqchi Maya for reproductive disorders the most prominent were the Piperaceae (15%) and Menispermiaceae. Our Previous work showed that extracts from form Piper and Cissampelos species bound to both and progesterone and the estrogen receptors. In this work active extracts from Piper aeruginosibaccum Trelease, P auritum, P tuerckheimii and Cissampels tropaeolifolia were tested in functionalized cell based assays including a SEAP reporter gene and by qPCR of ER-responsive gene expression in MCF-7cells. In the reporter gene assay P aeruginosibaccum was estrogenic and enhanced E2 EFFECTS IN MCF-7 CELLS. P. tuerckheimi was not estrogenic alone but significantly enhanced the effects of E2 on SEAP reporter gene expression. Both altered mRNA expression of E2 responsive genes in MCF-7. Methods: this is collaborative project between University of Illinois at Chicago and University of San Carlos Guatemala City. 144 spices of plants were collected in Guatemala of which 57 used to treat a variety of women's reproductive health. The Genus Piperaraceae contains approximately 1000 species of herbs scrubs and small trees. Active extracts of the plants were tested in functionalized in cell-based bioassays including SEAP reporter genes. Results demonstrated altered mRNA expression of E2 responsive genes in MC-7 cells plants were collected in Guatemala of which 57 used. Conclusion of the 5 plants tested all were shown to contain components of binding to estrogenic receptor to a greater or lesser degree. These effects support the use of QEqchi Maya women in Guatemala for reproductive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reporter%20genes" title="reporter genes">reporter genes</a>, <a href="https://publications.waset.org/abstracts/search?q=MC7" title=" MC7"> MC7</a>, <a href="https://publications.waset.org/abstracts/search?q=guatemala%20piperaceae" title=" guatemala piperaceae"> guatemala piperaceae</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20health" title=" reproductive health"> reproductive health</a> </p> <a href="https://publications.waset.org/abstracts/48232/q-eqchi-mayan-piper-and-cissampelos-species-alter-reporter-genes-and-endogenous-genes-expression-in-mc-7-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48232.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">247</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> The Production of Reinforced Insulation Bricks out of the Concentration of Ganoderma lucidum Fungal Inoculums and Cement Paste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jovie%20Esquivias%20Nicolas">Jovie Esquivias Nicolas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ron%20Aldrin%20Lontoc%20Austria"> Ron Aldrin Lontoc Austria</a>, <a href="https://publications.waset.org/abstracts/search?q=Crisabelle%20Belleza%20Bautista"> Crisabelle Belleza Bautista</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariane%20Chiho%20Espinosa%20Bundalian"> Mariane Chiho Espinosa Bundalian</a>, <a href="https://publications.waset.org/abstracts/search?q=Owwen%20Kervy%20Del%20Rosario%20Castillo"> Owwen Kervy Del Rosario Castillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mary%20Angelyn%20Mercado%20Dela%20Cruz"> Mary Angelyn Mercado Dela Cruz</a>, <a href="https://publications.waset.org/abstracts/search?q=Heinrich%20Theraja%20Recana%20De%20Luna"> Heinrich Theraja Recana De Luna</a>, <a href="https://publications.waset.org/abstracts/search?q=Chriscell%20Gipanao%20Eustaquio"> Chriscell Gipanao Eustaquio</a>, <a href="https://publications.waset.org/abstracts/search?q=Desiree%20Laine%20Lauz%20Gilbas"> Desiree Laine Lauz Gilbas</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan%20Ignacio%20Legaspi"> Jordan Ignacio Legaspi</a>, <a href="https://publications.waset.org/abstracts/search?q=Larah%20Denise%20David%20Madrid"> Larah Denise David Madrid</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Linelle%20Malapote%20Mendoza"> Charles Linelle Malapote Mendoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazel%20Maxine%20Manalad%20Reyes"> Hazel Maxine Manalad Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Carl%20Justine%20Nabora%20Saberdo"> Carl Justine Nabora Saberdo</a>, <a href="https://publications.waset.org/abstracts/search?q=Claire%20Mae%20Rendon%20Santos"> Claire Mae Rendon Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In response to the global race in discovering the next advanced sustainable material that will reduce our ecological footprint, the researchers aimed to create a masonry unit which is competent in physical edifices and other constructional facets. From different proven researches, mycelium has been concluded that when dried can be used as a robust and waterproof building material that can be grown into explicit forms, thus reducing the processing requirements. Hypothesizing inclusive measures to attest fungi’s impressive structural qualities and absorbency, the researchers projected to perform comparative analyses in creating mycelium bricks from mushroom spores of G. lucidum. Three treatments were intended to classify the most ideal concentration of clay and substrate fixings. The substrate bags fixed with 30% clay and 70% mixings indicated highest numerical frequencies in terms of full occupation of fungal mycelia. Subsequently, sorted parts of white portions from the treatment were settled in a thermoplastic mold and burnt. Three proportional concentrations of cultivated substrate and cement were also prioritized to gather results of variation focused on the weights of the bricks in the Water Absorption Test and Durability Test. Fungal inoculums with solutions of cement showed small to moderate amounts of decrease and increase in load. This proves that the treatments did not show any significant difference when it comes to strength, efficiency and absorption capacity. Each of the concentration is equally valid and could be used in supporting the worldwide demands of creating numerous bricks while also taking into consideration the recovery of our nature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mycelium" title="mycelium">mycelium</a>, <a href="https://publications.waset.org/abstracts/search?q=fungi" title=" fungi"> fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=fungal%20mycelia" title=" fungal mycelia"> fungal mycelia</a>, <a href="https://publications.waset.org/abstracts/search?q=durability%20test" title=" durability test"> durability test</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20absorption%20test" title=" water absorption test"> water absorption test</a> </p> <a href="https://publications.waset.org/abstracts/109275/the-production-of-reinforced-insulation-bricks-out-of-the-concentration-of-ganoderma-lucidum-fungal-inoculums-and-cement-paste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109275.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Generative Behaviors and Psychological Well-Being in Mexican Elders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20L.%20Gonzalez-Celis">Ana L.

The challenge to feel better is to find those resources that seniors have. For that reason, psychological well-being has shown interest in the study of the affect and life satisfaction (hedonic well-being), while from a more recent tradition, focus on the development of capabilities and the personal growth, considering both as the main indicators of the quality of life. A resource that can be used in the later age is generativity, which refers to the ability of older people to develop and grow through activities that contribute with the improvement of the context in which they live and participate. In this way the generative interest is understood as a favourable attitude that contribute to the common benefit while strengthening and enriching the social institutions, to ensure continuity between generations and social development. On the other hand, generative behavior, differentiating from generative interest, is the expression of that attitude reflected in activities that make a social contribution and a benefit for generations to come. Hence the purpose of the research was to test if there is an association between the generative behaviour type and the psychological well-being with their dimensions. For this reason 188 Mexican adults from 60 to 94 years old (M = 69.78), 67% women, 33% men, completed two instruments: The Ryff’s Well-Being Scales to measure psychological well-being with 39 items with two dimensions (Hedonic and Eudaimonic well-being), and the Loyola’s Generative Behaviors Scale, grouped in five categories: Knowledge transmitted to the next generation, things to be remember, creativity, be productive, contribution to the community, and responsibility of other people. In addition, the socio-demographic data sheet was tested, and self-reported health status. The results indicated that the psychological well-being and its dimensions were significantly associated with the presence of generative behavior, where the level of well-being was higher when the frequency of some generative behaviour excelled; finding that the behavior with greater psychological well-being (M = 81.04, SD = 8.18) was "things to be remembered"; while with greater hedonic well-being (M = 73.39, SD = 12.19) was the behavior "responsibility of other people"; and with greater Eudaimonic well-being (M = 84.61, SD = 6.63), was the behavior "things to be remembered”. The most important findings highlight the importance of generative behaviors in adulthood, finding empirical evidence that the generativity in the last stage of life is associated with well-being. However, by finding differences in the types of generative behaviors at the level of well-being, is proposed the idea that generativity is not situated as an isolated construct, but needs other contextualized and related constructs that can simultaneously operate at different levels, taking into account the relationship between the environment and the individual, encompassing both the social and psychological dimension. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eudaimonic%20well-being" title="eudaimonic well-being">eudaimonic well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=generativity" title=" generativity"> generativity</a>, <a href="https://publications.waset.org/abstracts/search?q=hedonic%20well-being" title=" hedonic well-being"> hedonic well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=Mexican%20elders" title=" Mexican elders"> Mexican elders</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20well-being" title=" psychological well-being"> psychological well-being</a> </p> <a href="https://publications.waset.org/abstracts/65012/generative-behaviors-and-psychological-well-being-in-mexican-elders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65012.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">273</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Semi-Autonomous Surgical Robot for Pedicle Screw Insertion on ex vivo Bovine Bone: Improved Workflow and Real-Time Process Monitoring </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robnier%20Reyes">Robnier Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20J.%20P.%20Marques"> Andrew J.

The LBR Med is a collaborative robotic arm that is meant to work with a surgeon to streamline surgical workflow. It has 7 degrees of freedom and thus can be easily oriented. Position and torque sensors at each joint allow it to maintain a position accuracy of 150 µm with real-time force and torque feedback, making it ideal for complex surgical procedures. Spinal fusion procedures involve the placement of as many as 20 pedicle screws, requiring a great deal of accuracy due to proximity to the spinal canal and surrounding vessels. Any deviation from intended path can lead to major surgical complications. Assistive surgical robotic systems are meant to serve as collaborative devices easing the workload of the surgeon, thereby improving pedicle screw placement by mitigating fatigue related inaccuracies. Moreover, robotic spinal systems have shown marked improvements over conventional freehanded techniques in both screw placement accuracy and fusion quality and have greatly reduced the need for screw revision, intraoperatively and post-operatively. However, current assistive spinal fusion robots, such as the ROSA Spine, are limited in functionality to positioning surgical instruments. While they offer a small degree of improvement in pedicle screw placement accuracy, they do not alleviate surgeon fatigue, nor do they provide real-time force and torque feedback during screw insertion. We propose a semi-autonomous surgical robot workflow for spinal fusion where the surgeon guides the robot to its initial position and orientation, and the robot drives the pedicle screw accurately into the vertebra. Here, we demonstrate feasibility by inserting pedicle screws into ex-vivo bovine rib bone. The robot monitors position, force and torque with respect to predefined values selected by the surgeon to ensure the highest possible spinal fusion quality. The workflow alleviates the strain on the surgeon by having the robot perform the screw placement while the ability to monitor the process in real-time keeps the surgeon in the system loop. The approach we have taken in terms of level autonomy for the robot reflects its ability to safely collaborate with the surgeon in the operating room without external navigation systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ex%20vivo%20bovine%20bone" title="ex vivo bovine bone">ex vivo bovine bone</a>, <a href="https://publications.waset.org/abstracts/search?q=pedicle%20screw" title=" pedicle screw"> pedicle screw</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20robot" title=" surgical robot"> surgical robot</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20workflow" title=" surgical workflow"> surgical workflow</a> </p> <a href="https://publications.waset.org/abstracts/103298/semi-autonomous-surgical-robot-for-pedicle-screw-insertion-on-ex-vivo-bovine-bone-improved-workflow-and-real-time-process-monitoring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103298.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> Effects of an Envious Experience on Schadenfreude and Economic Decisions Making</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Reyes">Pablo Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanessa%20Riveros%20Fiallo"> Vanessa Riveros Fiallo</a>, <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Acevedo"> Cesar Acevedo</a>, <a href="https://publications.waset.org/abstracts/search?q=Camila%20Castellanos"> Camila Castellanos</a>, <a href="https://publications.waset.org/abstracts/search?q=Catalina%20Moncaleano"> Catalina Moncaleano</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20F.%20Parra"> Maria F.

These are mediated by interpersonal relationship and language. Such emotions are subdivided into moral and comparison. The present research emphasizes two comparative emotions: Envy and Schadenfreude. Envy arises when a person lack of quality, possessions or achievements and these are superior in someone else. The Schadenfreude (SC) expresses the pleasure that someone experienced by the misfortune of the other. The relationship between both emotions has been questioned before. Hence there are reports showing that envy increases and modulates SC response. Other documents suggest that envy causes SC response. However, the methodological approach of the topic has been made through self-reports, as well as the hypothetical scenarios. Given this problematic, the neuroscience social framework provides an alternative and demonstrates that social emotions have neurophysiological correlates that can be measured. This is relevant when studying social emotions that are reprehensible like envy or SC are. When tested, the individuals tend to report low ratings due to social desirability. In this study, it was drawn up a proposal in research's protocol and the progress on its own piloting. The aim is to evaluate the effect of feeling envy and Schadenfreude has on the decision-making process, as well as the cooperative behavior in an economic game. To such a degree, it was proposed an experimental model that will provoke to feel envious by performing games against an unknown opponent. The game consists of asking general knowledge questions. The difficulty level in questions and the strangers' facial response have been manipulated in order to generate an ecological comparison framework and be able to arise both envy and SC emotions. During the game, an electromyography registry will be made for two facial muscles that have been associated with the expressiveness of envy and SC emotions. One of the innovations of the current proposal is the measurement of the effect that emotions have on a specific behavior. To that extent, it was evaluated the effect of each condition on the dictators' economic game. The main intention is to evaluate if a social emotion can modulate actions that have been associated with social norms, in the literacy. The result of the evaluation of a pilot model (without electromyography record and self-report) have shown an association between envy and SC, in a way that as the individuals report a greater sense of envy, the greater the chance to experience SC. The results of the economic game show a slight tendency towards profit maximization decisions. It is expected that at the time of using real cash this behavior will be strengthened and also to correlate with the responses of electromyography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=envy" title="envy">envy</a>, <a href="https://publications.waset.org/abstracts/search?q=schadenfreude" title=" schadenfreude"> schadenfreude</a>, <a href="https://publications.waset.org/abstracts/search?q=electromyography" title=" electromyography"> electromyography</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20games" title=" economic games"> economic games</a> </p> <a href="https://publications.waset.org/abstracts/75314/effects-of-an-envious-experience-on-schadenfreude-and-economic-decisions-making" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75314.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">370</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> Envy and Schadenfreude Domains in a Model of Neurodegeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hernando%20Santamar%C3%ADa-Garc%C3%ADa">Hernando Santamaría-García</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20B%C3%A1ez"> Sandra Báez</a>, <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Reyes"> Pablo Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Santamar%C3%ADa-Garc%C3%ADa"> José Santamaría-García</a>, <a href="https://publications.waset.org/abstracts/search?q=Diana%20Matallana"> Diana Matallana</a>, <a href="https://publications.waset.org/abstracts/search?q=Adolfo%20Garc%C3%ADa"> Adolfo García</a>, <a href="https://publications.waset.org/abstracts/search?q=Agust%C3%ADn%20Iba%C3%B1ez"> Agustín Ibañez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of moral emotions (i.e., Schadenfreude and envy) is critical to understand the ecological complexity of everyday interactions between cognitive, affective, and social cognition processes. Most previous studies in this area have used correlational imaging techniques and framed Schadenfreude and envy as monolithic domains. Here, we profit from a relevant neurodegeneration model to disentangle the brain regions engaged in three dimensions of Schadenfreude and envy: deservingness, morality, and legality. We tested 20 patients with behavioral variant frontotemporal dementia (bvFTD), 24 patients with Alzheimer’s disease (AD), as a contrastive neurodegeneration model, and 20 healthy controls on a novel task highlighting each of these dimensions in scenarios eliciting Schadenfreude and envy. Compared with the AD and control groups, bvFTD patients obtained significantly higher scores on all dimensions for both emotions. Interestingly, the legal dimension for both envy and Schadenfreude elicited higher emotional scores than the deservingness and moral dimensions. Furthermore, correlational analyses in bvFTD showed that higher envy and Schadenfreude scores were associated with greater deficits in social cognition, inhibitory control, and behavior. Brain anatomy findings (restricted to bvFTD and controls) confirmed differences in how these groups process each dimension. Schadenfreude was associated with the ventral striatum in all subjects. Also, in bvFTD patients, increased Schadenfreude across dimensions was negatively correlated with regions supporting social-value rewards, mentalizing, and social cognition (frontal pole, temporal pole, angular gyrus and precuneus). In all subjects, all dimensions of envy positively correlated with the volume of the anterior cingulate cortex, a region involved in processing unfair social comparisons. By contrast, in bvFTD patients, the intensified experience of envy across all dimensions was negatively correlated with a set of areas subserving social cognition, including the prefrontal cortex, the parahippocampus, and the amygdala. Together, the present results provide the first lesion-based evidence for the multidimensional nature of the emotional experiences of envy and Schadenfreude. Moreover, this is the first demonstration of a selective exacerbation of envy and Schadenfreude in bvFTD patients, probably triggered by atrophy to social cognition networks. Our results offer new insights into the mechanisms subserving complex emotions and moral cognition in neurodegeneration, paving the way for groundbreaking research on their interaction with other cognitive, social, and emotional processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20cognition" title="social cognition">social cognition</a>, <a href="https://publications.waset.org/abstracts/search?q=moral%20emotions" title=" moral emotions"> moral emotions</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroimaging" title=" neuroimaging"> neuroimaging</a>, <a href="https://publications.waset.org/abstracts/search?q=frontotemporal%20dementia" title=" frontotemporal dementia"> frontotemporal dementia</a> </p> <a href="https://publications.waset.org/abstracts/75106/envy-and-schadenfreude-domains-in-a-model-of-neurodegeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75106.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> The Impact of COVID-19 Health Measures on Adults with Multiple Chemical Sensitivity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riina%20I.%20Bray">Riina I.

Since the arrival of the COVID-19 pandemic and associated health measures, people experiencing MCS (PEMCS) are at a heightened risk of environmental exposures associated with cleaners, disinfectants, and sanitizers. Little attention has been paid to the well-being of PEMCS in the context of the COVID-19 pandemic. Objective: This study assesses the lived experiences of Canadian adults with MCS in relation to their living environment, access to healthcare, and levels of perceived social support before and during the pandemic. Methods: A total of 119 PEMCS completed an online questionnaire. McNemar Chi-Squared and Wilcoxon Signed Rank tests were used to evaluate if there were statistically significant changes in participants’ perception of their living environment, access to healthcare, and levels of social support before and after March 11, 2020. Results: Both positive and negative outcomes were noted. Participants reported an increase in exposure to disinfectants/sanitizers that entered their living environment (p<.001). There was a reported decrease in access to a family doctor during the pandemic (p<0.001). Although PEMCS experienced increased social isolation (p<0.001), they also reported an increase in understanding from family (p<0.029) and a decrease in stigma for wearing personal protective equipment (p<0.001). Conclusion: PEMCS reported experiencing: increased exposure to disinfectants or sanitizers, a loss of social support, and barriers in accessing healthcare during the pandemic. However, COVID-19 provided an opportunity to normalize the living conditions of PEMCS, such as wearing masks and social isolation. These findings can guide decision-makers on the importance of implementing nontoxic alternatives for cleaning and disinfection, as well as improving accommodation measures for PEMCS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=covid-19" title="covid-19">covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20chemical%20sensitivity" title=" multiple chemical sensitivity"> multiple chemical sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=MCS" title=" MCS"> MCS</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20isolation" title=" social isolation"> social isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20environment" title=" physical environment"> physical environment</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare" title=" healthcare"> healthcare</a> </p> <a href="https://publications.waset.org/abstracts/155220/the-impact-of-covid-19-health-measures-on-adults-with-multiple-chemical-sensitivity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155220.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> From Myth to Screen: A Cultural Criticism of the Adaptation of Nordic Mythology in Marvel Cinematic Universe’s Thor Trilogy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vathya%20Anindita%20Putri">Vathya Anindita Putri</a>, <a href="https://publications.waset.org/abstracts/search?q=Henny%20Saptatia%20Drajati%20Nugrahani"> Henny Saptatia Drajati Nugrahani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to explore the representation of Nordic mythology in the commercial film titled “Thor” produced by the Marvel Cinematic Universe. First, the Nordic mythology adaptation and representation in “Thor” compared to other media. Second, the importance of using the mise en scene technique, the comprehensive portrayal of Nordic mythology and the audience's experiences in enjoying the film. This research is conducted using qualitative methods. The two research questions are analyzed using three theories: Adaptation theory by Robert Stam, Mise en Scene theory by Jean-Luc Godard, and Cultural Criticism theory by Michel Foucault. Robert Stam emphasizes the importance of social and historical in understanding film adaptations. Film adaptations always occur in a specific cultural and historical context; therefore, authors and producers must consider these factors when creating a successful adaptation. Jean-Luc Godard uses the “politiques des auteurs” approach to understand that films are not just cultural products made for entertainment, but they are works of art by authors and directors. It is important to explore how authors and directors convey their ideas and emotions in their films, in this case, a film set in Nordic mythology. Foucault takes an approach to analyzing power that considers how power operates and influences social relationships in a specific context. Foucault’s theory is used to analyze how the representation of Nordic mythology is used as an instrument of power by the Marvel Cinematic Universe to influence how the audience views Nordic mythology. The initial findings of this research are that the fusion of Nordic mythology with modern superhero storytelling in the film “Thor” produced by Marvel, is successful. The film contains conflicts in the modern world and represents the symbolism of Nordic mythology. The rich and interesting atmosphere of Nordic mythology is presented through epic battle scenes, captivating character roles, and the use of visual effects that make the film more vivid and real. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptation%20theory" title="adaptation theory">adaptation theory</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20criticism%20theory" title=" cultural criticism theory"> cultural criticism theory</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20criticism" title=" film criticism"> film criticism</a>, <a href="https://publications.waset.org/abstracts/search?q=Marvel%20cinematic%20universe" title=" Marvel cinematic universe"> Marvel cinematic universe</a>, <a href="https://publications.waset.org/abstracts/search?q=Mise%20en%20Scene%20theory" title=" Mise en Scene theory"> Mise en Scene theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Nordic%20mythology" title=" Nordic mythology"> Nordic mythology</a> </p> <a href="https://publications.waset.org/abstracts/167067/from-myth-to-screen-a-cultural-criticism-of-the-adaptation-of-nordic-mythology-in-marvel-cinematic-universes-thor-trilogy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167067.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Dendroremediation of a Defunct Lead Acid Battery Recycling Site</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alejandro%20Ruiz-Olivares">Alejandro Ruiz-Olivares</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20del%20Carmen%20Gonz%C3%A1lez-Ch%C3%A1vez"> M. del Carmen González-Chávez</a>, <a href="https://publications.waset.org/abstracts/search?q=Rogelio%20Carrillo-Gonz%C3%A1lez"> Rogelio Carrillo-González</a>, <a href="https://publications.waset.org/abstracts/search?q=Martha%20Reyes-Ramos"> Martha Reyes-Ramos</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Su%C3%A1rez%20Espinosa"> Javier Suárez Espinosa </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Use of automobiles has increased and proportionally, the demand for batteries to impulse them. When the device is aged, all the battery materials are reused through lead acid battery recycling (LABR). Importation of used lead acid batteries in Mexico has increased in the last years since many recycling factories have been settled in the country. Inadequate disposal of lead-acid battery recycling (LABR) wastes left soil severely polluted with Pb, Cu, and salts (Na+, SO2− 4, PO3− 4). Soil organic amendments may contribute with essential nutrients and sequester (scavenger compounds) metals to allow plant establishment. The objective of this research was to revegetate a former lead-acid battery recycling site aided with organic amendments. Seven tree species (Acacia farnesiana, Casuarina equisetifolia, Cupressus lusitanica, Eucalyptus obliqua, Fraxinus excelsior, Prosopis laevigata and Pinus greggii) and two organic amendments (vermicompost and vermicompost + sawdust mixture) were tested for phytoremediation of a defunct LABR site. Plants were irrigated during the dry season. Monitoring of the soils was carried out during the experiment: Available metals, salts concentrations and their spatial pattern in soil were analyzed. Plant species and amendments were compared through analysis of covariance and longitudinal analysis. High concentrations of extractable (DTPA-TEA-CaCl₂) metals (up to 15,685 mg kg⁻¹ and 478 mg kg⁻¹ for Pb and Cu) and soluble salts (292 mg kg-1 and 23,578 mg kg-1 for PO3− 4and SO2− 4) were found in the soil after three and six months of setting up the experiment. Lead and Cu concentrations were depleted in the rhizosphere after amendments addition. Spatial pattern of PO3− 4, SO2− 4 and DTPA-extractable Pb and Cu changed slightly through time. In spite of extreme soil conditions the plant species planted: A. farnesiana, E. obliqua, C. equisetifolia and F. excelsior had 100% of survival. Available metals and salts differently affected each species. In addition, negative effect on growth due to Pb accumulated in shoots was observed only in C. lusitanica. Many specimens accumulated high concentrations of Pb ( > 1000 mg kg-1) in shoots. C. equisetifolia and C. lusitanica had the best rate of growth. Based on the results, all the evaluated species may be useful for revegetation of Pb-polluted soils. Besides their use in phytoremediation, some ecosystem services can be obtained from the woodland such as encourage wildlife, wood production, and carbon sequestration. Further research should be conducted to analyze these services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title="heavy metals">heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=inadequate%20disposal" title=" inadequate disposal"> inadequate disposal</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20amendments" title=" organic amendments"> organic amendments</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoremediation%20with%20trees" title=" phytoremediation with trees"> phytoremediation with trees</a> </p> <a href="https://publications.waset.org/abstracts/65517/dendroremediation-of-a-defunct-lead-acid-battery-recycling-site" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65517.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">284</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Continuous Improvement of Teaching Quality through Course Evaluation by the Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valerie%20Follonier">Valerie Follonier</a>, <a href="https://publications.waset.org/abstracts/search?q=Henrike%20Hamelmann"> Henrike Hamelmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Michel%20Jullien"> Jean-Michel Jullien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Distance Learning University in Switzerland (UniDistance) is offering bachelor and master courses as well as further education programs. The professors and their assistants work at traditional Swiss universities and are giving their courses at UniDistance following a blended learning and flipped classroom approach. A standardized course evaluation by the students has been established as a component of a quality improvement process. The students’ feedback enables the stakeholders to identify areas of improvement, initiate professional development for the teaching teams and thus continuously augment the quality of instruction. This paper describes the evaluation process, the tools involved and how the approach involving all stakeholders helps forming a culture of quality in teaching. Additionally, it will present the first evaluation results following the new process. Two software tools have been developed to support all stakeholders in the process of the semi-annual formative evaluation. The first tool allows to create the survey and to assign it to the relevant courses and students. The second tool presents the results of the evaluation to the stakeholders, providing specific features for the teaching teams, the dean, the directorate and EDUDL+ (Educational development unit distance learning). The survey items were selected in accordance with the e-learning strategy of the institution and are formulated to support the professional development of the teaching teams. By reviewing the results the teaching teams become aware of the opinion of the students and are asked to write a feedback for the attention of their dean. The dean reviews the results of the faculty and writes a general report about the situation of the faculty and the possible improvements intended. Finally, EDUDL+ writes a final report summarising the evaluation results. A mechanism of adjustable warnings allows it to generate quality indicators for each module. These are summarised for each faculty and globally for the whole institution in order to increase the vigilance of the responsible. The quality process involves changing the indicators regularly to focus on different areas each semester, to facilitate the professional development of the teaching teams and to progressively augment the overall teaching quality of the institution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continuous%20improvement%20process" title="continuous improvement process">continuous improvement process</a>, <a href="https://publications.waset.org/abstracts/search?q=course%20evaluation" title=" course evaluation"> course evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20learning" title=" distance learning"> distance learning</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20tools" title=" software tools"> software tools</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20quality" title=" teaching quality"> teaching quality</a> </p> <a href="https://publications.waset.org/abstracts/52790/continuous-improvement-of-teaching-quality-through-course-evaluation-by-the-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52790.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">259</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> 1D/3D Modeling of a Liquid-Liquid Two-Phase Flow in a Milli-Structured Heat Exchanger/Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antoinette%20Maarawi">Antoinette Maarawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zoe%20Anxionnaz-Minvielle"> Zoe Anxionnaz-Minvielle</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Coste"> Pierre Coste</a>, <a href="https://publications.waset.org/abstracts/search?q=Nathalie%20Di%20Miceli%20Raimondi"> Nathalie Di Miceli Raimondi</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Cabassud"> Michel Cabassud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Milli-structured heat exchanger/reactors have been recently widely used, especially in the chemical industry, due to their enhanced performances in heat and mass transfer compared to conventional apparatuses. In our work, the ‘DeanHex’ heat exchanger/reactor with a 2D-meandering channel is investigated both experimentally and numerically. The square cross-sectioned channel has a hydraulic diameter of 2mm. The aim of our study is to model local physico-chemical phenomena (heat and mass transfer, axial dispersion, etc.) for a liquid-liquid two-phase flow in our lab-scale meandering channel, which represents the central part of the heat exchanger/reactor design. The numerical approach of the reactor is based on a 1D model for the flow channel encapsulated in a 3D model for the surrounding solid, using COMSOL Multiphysics V5.5. The use of the 1D approach to model the milli-channel reduces significantly the calculation time compared to 3D approaches, which are generally focused on local effects. Our 1D/3D approach intends to bridge the gap between the simulation at a small scale and the simulation at the reactor scale at a reasonable CPU cost. The heat transfer process between the 1D milli-channel and its 3D surrounding is modeled. The feasibility of this 1D/3D coupling was verified by comparing simulation results to experimental ones originated from two previous works. Temperature profiles along the channel axis obtained by simulation fit the experimental profiles for both cases. The next step is to integrate the liquid-liquid mass transfer model and to validate it with our experimental results. The hydrodynamics of the liquid-liquid two-phase system is modeled using the ‘mixture model approach’. The mass transfer behavior is represented by an overall volumetric mass transfer coefficient ‘kLa’ correlation obtained from our experimental results in the millimetric size meandering channel. The present work is a first step towards the scale-up of our ‘DeanHex’ expecting future industrialization of such equipment. Therefore, a generalized scaled-up model of the reactor comprising all the transfer processes will be built in order to predict the performance of the reactor in terms of conversion rate and energy efficiency at an industrial scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liquid-liquid%20mass%20transfer" title="liquid-liquid mass transfer">liquid-liquid mass transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=milli-structured%20reactor" title=" milli-structured reactor"> milli-structured reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=1D%2F3D%20model" title=" 1D/3D model"> 1D/3D model</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20intensification" title=" process intensification"> process intensification</a> </p> <a href="https://publications.waset.org/abstracts/128595/1d3d-modeling-of-a-liquid-liquid-two-phase-flow-in-a-milli-structured-heat-exchangerreactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128595.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Effect of Antimony on Microorganisms in Aerobic and Anaerobic Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barrera%20C.%20Monserrat">Barrera C.

It is present in the environment in two oxidation states: antimonite (Sb (III)) and antimony (Sb (V)). Sb (III) is toxic to several aquatic organisms, but the potential inhibitory effect of Sb species for microorganisms has not been extensively evaluated. The fate and possible toxic impact of antimony on aerobic and anaerobic wastewater treatment systems are unknown. For this reason, the objective of this study was to evaluate the microbial toxicity of Sb (V) and Sb (III) in aerobic and anaerobic environments. Sb(V) and Sb(III) were used as potassium hexahydroxoantimonate (V) and potassium antimony tartrate, respectively (Sigma-Aldrich). The toxic effect of both Sb species in anaerobic environments was evaluated on methanogenic activity and the inhibition of hydrogen production of microorganisms from a wastewater treatment bioreactor. For the methanogenic activity, batch experiments were carried out in 160 mL serological bottles; each bottle contained basal mineral medium (100 mL), inoculum (1.5 g of VSS/L), acetate (2.56 g/L) as substrate, and variable concentrations of Sb (V) or Sb (III). Duplicate bioassays were incubated at 30 ± 2°C on an orbital shaker (105 rpm) in the dark. Methane production was monitored by gas chromatography. The hydrogen production inhibition tests were carried out in glass bottles with a working volume of 0.36 L. Glucose (50 g/L) was used as a substrate, pretreated inoculum (5 g VSS/L), mineral medium and varying concentrations of the two species of antimony. The bottles were kept under stirring and at a temperature of 35°C in an AMPTSII device that recorded hydrogen production. The toxicity of Sb on aerobic microorganisms (from a wastewater activated sludge treatment plant) was tested with a Microtox standardized toxicity test and respirometry. Results showed that Sb (III) is more toxic than Sb (V) for methanogenic microorganisms. Sb (V) caused a 50% decrease in methanogenic activity at 250 mg/L. In contrast, exposure to Sb (III) resulted in a 50% inhibition at a concentration of only 11 mg/L, and an almost complete inhibition (95%) at 25 mg/L. For hydrogen-producing microorganisms, Sb (III) and Sb (V) inhibited 50% of this production with 12.6 mg/L and 87.7 mg/L, respectively. The results for aerobic environments showed that 500 mg/L of Sb (V) do not inhibit the Allivibrio fischeri (Microtox) activity or specific oxygen uptake rate of activated sludge. In the case of Sb (III), this caused a loss of 50% of the respiration of the microorganisms at concentrations below 40 mg/L. The results obtained indicate that the toxicity of the antimony will depend on the speciation of this metalloid and that Sb (III) has a significantly higher inhibitory potential compared to Sb (V). It was shown that anaerobic microorganisms can reduce Sb (V) to Sb (III).

Indeed, in the face of climate change and strong demographic growth, groundwater, particularly in the basement, is increasingly in demand. The question of the sustainability of water resources in this type of environment is therefore becoming a major issue. Groundwater recharge can be natural or artificial. Unlike natural recharge, which often results from the natural infiltration of surface water (e.g. a share of rainfall), artificial recharge consists of causing water infiltration through appropriate developments to artificially replenish the water stock of an aquifer. Artificial recharge is, therefore, one of the measures that can be implemented to secure water supply, combat the effects of climate change, and, more generally, contribute to improving the quantitative status of groundwater bodies. It is in this context that the present research is conducted with the aim of developing artificial recharge in order to contribute to the sustainability of basement aquifers in a context of climatic variability and constantly increasing water needs of populations. In order to achieve the expected results, it is therefore important to determine the characteristics of the infiltration basins and to identify the areas suitable for their implementation. The geometry of the aquifer was reproduced, and the hydraulic properties of the aquifer were collected and characterized, including boundary conditions, hydraulic conductivity, effective porosity, recharge, Van Genuchten parameters, and saturation indices. The aquifer of the Sanon experimental site is made up of three layers, namely the saprolite, the fissured horizon, and the healthy basement. Indeed, the saprolite and the fissured medium were considered for the simulations. The first results with FEFLOW model show that the water table reacts continuously for the first 100 days before stabilizing. The hydraulic charge increases by an average of 1 m. The further away from the basin, the less the water table reacts. However, if a variable hydraulic head is imposed on the basins, it can be seen that the response of the water table is not uniform over time. The lower the basin hydraulic head, the less it affects the water table. These simulations must be continued by improving the characteristics of the basins in order to obtain the appropriate characteristics for a good recharge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basement%20area" title="basement area">basement area</a>, <a href="https://publications.waset.org/abstracts/search?q=FEFLOW" title=" FEFLOW"> FEFLOW</a>, <a href="https://publications.waset.org/abstracts/search?q=infiltration%20basin" title=" infiltration basin"> infiltration basin</a>, <a href="https://publications.waset.org/abstracts/search?q=MAR" title=" MAR"> MAR</a> </p> <a href="https://publications.waset.org/abstracts/162819/evaluation-of-the-conditions-of-managed-aquifer-recharge-in-the-west-african-basement-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162819.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Viability Analysis of a Centralized Hydrogen Generation Plant for Use in Oil Refining Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20F%C3%BAnez%20Guerra">C.

Unstable energy markets, an increasing focus on climate change and its sustainable development is forcing businesses to pursue new solutions in order to ensure future economic growth. This has led to the interest in using hydrogen as an energy carrier in transportation and industrial applications. As an energy carrier, hydrogen is accessible and holds a high gravimetric energy density. Abundant in hydrocarbons, hydrogen can play an important role in the shift towards low-emission fossil value chains. By combining hydrogen production by natural gas reforming with carbon capture and storage, the overall CO2 emissions are significantly reduced. In addition, the flexibility of hydrogen as an energy storage makes it applicable as a stabilizer in the renewable energy mix. The recent development in hydrogen fuel cells is also raising the expectations for a hydrogen powered transportation sector. Hydrogen value chains exist to a large extent in the industry today. The global hydrogen consumption was approximately 50 million tonnes (7.2 EJ) in 2013, where refineries, ammonia, methanol production and metal processing were main consumers. Natural gas reforming produced 48% of this hydrogen, but without carbon capture and storage (CCS). The total emissions from the production reached 500 million tonnes of CO2, hence alternative production methods with lower emissions will be necessary in future value chains. Hydrogen from electrolysis is used for a wide range of industrial chemical reactions for many years. Possibly, the earliest use was for the production of ammonia-based fertilisers by Norsk Hydro, with a test reactor set up in Notodden, Norway, in 1927. This application also claims one of the world’s largest electrolyser installations, at Sable Chemicals in Zimbabwe. Its array of 28 electrolysers consumes 80 MW per hour, producing around 21,000 Nm3/h of hydrogen. These electrolysers can compete if cheap sources of electricity are available and natural gas for steam reforming is relatively expensive. Because electrolysis of water produces oxygen as a by-product, a system of Autothermal Reforming (ATR) utilizing this oxygen has been analyzed. Replacing the air separation unit with electrolysers produces the required amount of oxygen to the ATR as well as additional hydrogen. The aim of this paper is to evaluate the technical and economic potential of large-scale production of hydrogen for oil refining industry. Sensitivity analysis of parameters such as investment costs, plant operating hours, electricity price and sale price of hydrogen and oxygen are performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autothermal%20reforming" title="autothermal reforming">autothermal reforming</a>, <a href="https://publications.waset.org/abstracts/search?q=electrolyser" title=" electrolyser"> electrolyser</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20gas" title=" natural gas"> natural gas</a>, <a href="https://publications.waset.org/abstracts/search?q=steam%20methane%20reforming" title=" steam methane reforming"> steam methane reforming</a> </p> <a href="https://publications.waset.org/abstracts/68206/viability-analysis-of-a-centralized-hydrogen-generation-plant-for-use-in-oil-refining-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68206.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">211</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Evaluation of Monoterpenes Induction in Ugni molinae Ecotypes Subjected to a Red Grape Caterpillar (Lepidoptera: Arctiidae) Herbivory </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Chacon-Fuentes">Manuel Chacon-Fuentes</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Bardehle"> Leonardo Bardehle</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Lizama"> Marcelo Lizama</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudio%20Reyes"> Claudio Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Andres%20Quiroz"> Andres Quiroz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The insect-plant interaction is a complex process in which the plant is able to release chemical signaling that modifies the behavior of insects. Insect herbivory can trigger mechanisms that allow the increase in the production of secondary metabolites that allow coping against the herbivores. Monoterpenes are a kind of secondary metabolites involved in direct defense acting as repellents of herbivorous or even in indirect defense acting as attractants for insect predators. In addition, an increase of the monoterpenes concentration is an effect commonly associated with the herbivory. Hence, plants subjected to damage by herbivory increase the monoterpenes production in comparison to plants without herbivory. In this framework, co-evolutionary aspects play a fundamental role in the adaptation of the herbivorous to their host and in the counter-adaptive strategies of the plants to avoid the herbivorous. In this context, Ugni molinae 'murtilla' is a native shrub from Chile characterized by its antioxidant activity mainly related to the phenolic compounds presents in its fruits. The larval stage of the red grape caterpillar Chilesia rudis Butler (Lepidoptera: Arctiidae) has been reported as an important defoliator of U. molinae. This insect is native from Chile and probably has been involved in a co-evolutionary process with murtilla. Therefore, we hypothesized that herbivory by the red grape caterpillar increases the emission of monoterpenes in Ugni molinae. Ecotypes 19-1 and 22-1 of murtilla were established and maintained at 25° C in the Laboratorio de Química Ecológica at Universidad de La Frontera. Red grape caterpillars of ⁓40 mm were collected near to Temuco (Chile) from grasses, and they were deprived of food for 24 h before performing the assays. Ten caterpillars were placed on the foliage of the ecotypes 19-1 and 22-1 and allowed to feed during 48 h. After this time, caterpillars were removed from the ecotypes and monoterpenes were collected. A glass chamber was used to enclose the ecotypes and a Porapak-Q column was used to trap the monoterpenes. After 24 h of capturing, columns were desorbed with hexane. Then, samples were injected in a gas chromatograph coupled to mass spectrometer and monoterpenes were determined according to the NIST library. All the experiments were performed in triplicate. Results showed that α-pinene, β-phellandrene, limonene, and 1,8 cineole were the main monoterpenes released by murtilla ecotypes. For the ecotype 19-1, the abundance of α-pinene was significantly higher in plants subjected to herbivory (100%) in relation to control plants (54.58%). Moreover, β-phellandrene and 1,8 cineole were observed only in control plants. For ecotype 22-1, there was no significant difference in monoterpenes abundance. In conclusion, the results suggest a trade-off of β-phellandrene and 1,8 cineole in response to herbivory damage by red grape caterpillar generating an increase in α-pinene abundance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chilesia%20rudis" title="Chilesia rudis">Chilesia rudis</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20chromatography" title=" gas chromatography"> gas chromatography</a>, <a href="https://publications.waset.org/abstracts/search?q=monoterpenes" title=" monoterpenes"> monoterpenes</a>, <a href="https://publications.waset.org/abstracts/search?q=Ugni%20molinae" title=" Ugni molinae"> Ugni molinae</a> </p> <a href="https://publications.waset.org/abstracts/108703/evaluation-of-monoterpenes-induction-in-ugni-molinae-ecotypes-subjected-to-a-red-grape-caterpillar-lepidoptera-arctiidae-herbivory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108703.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Ethical Issues in AI: Analyzing the Gap Between Theory and Practice - A Case Study of AI and Robotics Researchers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sylvie%20Michel">Sylvie Michel</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuelle%20Gagnou"> Emmanuelle Gagnou</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanne%20Hamet"> Joanne Hamet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New major ethical dilemmas are posed by artificial intelligence. This article identifies an existing gap between the ethical questions that AI/robotics researchers grapple with in their research practice and those identified by literature review. The objective is to understand which ethical dilemmas are identified or concern AI researchers in order to compare them with the existing literature. This will enable to conduct training and awareness initiatives for AI researchers, encouraging them to consider these questions during the development of AI. Qualitative analyses were conducted based on direct observation of an AI/Robotics research team focused on collaborative robotics over several months. Subsequently, semi-structured interviews were conducted with 16 members of the team. The entire process took place during the first semester of 2023. The observations were analyzed using an analytical framework, and the interviews were thematically analyzed using Nvivo software. While the literature identifies three primary ethical concerns regarding AI—transparency, bias, and responsibility—the results firstly demonstrate that AI researchers are primarily concerned with the publication and valorization of their work, with the initial ethical concerns revolving around this matter. Questions arise regarding the extent to which to "market" publications and the usefulness of some publications. Research ethics are a central consideration for these teams. Secondly, another result shows that the researchers studied adopt a consequentialist ethics (though not explicitly formulated as such). They ponder the consequences of their development in terms of safety (for humans in relation to Robots/AI), worker autonomy in relation to the robot, and the role of work in society (can robots take over jobs?). Lastly, results indicate that the ethical dilemmas highlighted in the literature (responsibility, transparency, bias) do not explicitly appear in AI/Robotics research. AI/robotics researchers raise specific and pragmatic ethical questions, primarily concerning publications initially and consequentialist considerations afterward. Results demonstrate that these concerns are distant from the existing literature. However, the dilemmas highlighted in the literature also deserve to be explicitly contemplated by researchers. This article proposes that the journals these researchers target should mandate ethical reflection for all presented works. Furthermore, results suggest offering awareness programs in the form of short educational sessions for researchers. <p class="card-text"><strong>Keywords:</strong> <a
