Mineral jetfuel consists of a hydrocarbon mixture containing paraffins, naphthenes and aromatics, with low olefins content. In order to ensure their safety, several stringent requirements must be met by jetfuels, such as: high energy density, low risk of explosion, physicochemical stability and low pour point. In this context, aviation fuels eventually obtained from biofeedstocks (which have been coined as ‘biojetfuel’), must be used as ‘drop in’, since adaptations in aircraft engines are not desirable, to avoid problems with their operation reliability. Thus, potential aviation biofuels must present the same composition and physicochemical properties of conventional jetfuel. Among the potential feedtstocks for aviation biofuel, the babaçu oil, extracted from a palm tree extensively found in some regions of Brazil, contains expressive quantities of short chain saturated fatty acids and may be an interesting choice for biojetfuel production. In this study, biojetfuel was synthesized through homogeneous transesterification of babaçu oil using methanol and its properties were compared with petroleum-based jetfuel through measurements of oxidative stability, physicochemical properties and low temperature properties. The transesterification reactions were carried out using methanol and after decantation/wash procedures, the methyl esters were purified by molecular distillation under high vacuum at different temperatures. The results indicate significant improvement in oxidative stability and pour point of the products when compared to the fresh oil. After optimization of operational conditions, potential biojetfuel samples were obtained, consisting mainly of C8 esters, showing low pour point and high oxidative stability. Jet engine tests are being conducted in an automated test bed equipped with pollutant emissions analysers to study the operational performance of the biojetfuel that was obtained and compare with a mineral commercial jetfuel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biojetfuel" title="biojetfuel">biojetfuel</a>, <a href="https://publications.waset.org/abstracts/search?q=baba%C3%A7u%20oil" title=" babaçu oil"> babaçu oil</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stability" title=" oxidative stability"> oxidative stability</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20tests" title=" engine tests"> engine tests</a> </p> <a href="https://publications.waset.org/abstracts/44020/studies-on-biojetfuel-obtained-from-vegetable-oil-process-characteristics-engine-performance-and-their-comparison-with-mineral-jetfuel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44020.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">66</span> University of Sciences and Technology of Oran Mohamed Boudiaf (USTO-MB)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Mikchaela%20D.%20L.%20Feliciano">Patricia Mikchaela D.

It has been found to possess anti-inflammatory property, which stimulates hair growth in rats by inducing hair keratinocytes proliferation, causing water retention and preventing damage caused by heat, ultraviolet rays, and other microorganisms without abnormalities in hair follicles. The present study aimed to formulate 10% and 30% Propolis Hair Cream for use in enhancing hair properties. Raw propolis sample was tested for heavy metals using Atomic Absorption Spectroscopy; zinc and chromium were found to be present. Likewise, propolis was extracted in a percolator using 70% ethanol and concentrated under vacuum using a rotary evaporator. The propolis extract was analyzed for total flavonoid content. Compatibility of the propolis extract with excipients was evaluated using Differential Scanning Calorimetry (DSC). No significant changes in organoleptic properties, pH and viscosity of the formulated creams were noted after four weeks of storage at 2-8°C, 30°C, and 40°C. The formulated creams were found to be non-irritating based on the Modified Draize Rabbit Test. In vivo efficacy was evaluated based on thickness and tensile strength of hair grown on previously shaved rat skin. Results show that the formulated 30% propolis-based cream had greater hair enhancing properties than the 10% propolis cream, which had a comparable effect with minoxidil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomic%20absorption%20spectroscopy" title="atomic absorption spectroscopy">atomic absorption spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20scanning%20calorimetry%20%28DSC%29" title=" differential scanning calorimetry (DSC)"> differential scanning calorimetry (DSC)</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20draize%20rabbit%20test" title=" modified draize rabbit test"> modified draize rabbit test</a>, <a href="https://publications.waset.org/abstracts/search?q=propolis" title=" propolis"> propolis</a> </p> <a href="https://publications.waset.org/abstracts/46362/university-of-sciences-and-technology-of-oran-mohamed-boudiaf-usto-mb" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46362.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">344</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> TutorBot+: Automatic Programming Assistant with Positive Feedback based on LLMs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Mart%C3%ADnez-Araneda">Claudia Martínez-Araneda</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariella%20Guti%C3%A9rrez"> Mariella Gutiérrez</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20G%C3%B3mez"> Pedro Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Maldonado"> Diego Maldonado</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Segura"> Alejandra Segura</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Vidal-Castro"> Christian Vidal-Castro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this document is to showcase the preliminary work in developing an EduChatbot-type tool and measuring the effects of its use aimed at providing effective feedback to students in programming courses. This bot, hereinafter referred to as tutorBot+, was constructed based on chatGPT and is tasked with assisting and delivering timely positive feedback to students in the field of computer science at the Universidad Católica de Concepción. The proposed working method consists of four stages: (1) Immersion in the domain of Large Language Models (LLMs), (2) Development of the tutorBot+ prototype and integration, (3) Experiment design, and (4) Intervention. The first stage involves a literature review on the use of artificial intelligence in education and the evaluation of intelligent tutors, as well as research on types of feedback for learning and the domain of chatGPT. The second stage encompasses the development of tutorBot+, and the final stage involves a quasi-experimental study with students from the Programming and Database labs, where the learning outcome involves the development of computational thinking skills, enabling the use and measurement of the tool's effects. The preliminary results of this work are promising, as a functional chatBot prototype has been developed in both conversational and non-conversational versions integrated into an open-source online judge and programming contest platform system. There is also an exploration of the possibility of generating a custom model based on a pre-trained one tailored to the domain of programming. This includes the integration of the created tool and the design of the experiment to measure its utility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=chatGPT" title=" chatGPT"> chatGPT</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20strategies" title=" learning strategies"> learning strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=LLMs" title=" LLMs"> LLMs</a>, <a href="https://publications.waset.org/abstracts/search?q=timely%20feedback" title=" timely feedback"> timely feedback</a> </p> <a href="https://publications.waset.org/abstracts/172610/tutorbot-automatic-programming-assistant-with-positive-feedback-based-on-llms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172610.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">68</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> Lexicographic Rules on the Use of Technologies for Realization of the National Signs-Terms Inventory of Cultural Heritage Field in Libras</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gl%C3%A1ucio%20de%20Castro%20J%C3%BAnior">Gláucio de Castro Júnior</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Prometi"> Daniela Prometi</a>, <a href="https://publications.waset.org/abstracts/search?q=Patr%C3%ADcia%20Tuxi"> Patrícia Tuxi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The project 'Inventory Signs-terms of the cultural heritage field in Libras' provides for the establishment of an inventory of signs, terms relating to the field of cultural heritage in Libras, from the results of research in progress as the pilot project' Accessibility Communication, Translation and Interpretation to the Application Portal Libras Heritage 'and the Pilot Project' registration-signal terms for the preparation of bilingual lexicon Libras / Portuguese terms available in the Portal Heritage.

It contributes to a corpus-informed and learner-centered design of grammar presentation in EFL textbooks that enhances the authenticity and appropriateness of textbook language for target learners. The linguistic focus is will, would, can, could, may, might, shall, should, must. The native corpus is the spoken component of BNC2014 (hereafter BNCS2014). The spoken part is chosen because pedagogical purpose of the textbooks is communication-oriented. Using the standard query option of CQPweb, 5% of each of the nine modals was sampled from BNCS2014. The learner corpus is the POS-tagged Ten-thousand English Compositions of Chinese Learners (TECCL). All the essays under the 'secondary school' section were selected. A series of five secondary coursebooks comprise the textbook corpus. All the data in both the learner and the textbook corpora are retrieved through the concordance functions of WordSmith Tools (version, 5.0). Data analysis was divided into two parts. The first part compared the patterns of modal verbs in the textbook corpus and BNC2014 with respect to distributional features, semantic functions, and co-occurring constructions to examine whether the textbooks reflect the authentic use of English. Secondly, the learner corpus was analyzed in terms of the use (distributional features, semantic functions, and co-occurring constructions) and the misuse (syntactic errors, e.g., she can sings*.) of the nine modal verbs to uncover potential difficulties that confront learners. The analysis of distribution indicates several discrepancies between the textbook corpus and BNCS2014. The first four most frequent modal verbs in BNCS2014 are can, would, will, could, while can, will, should, could are the top four in the textbooks. Most strikingly, there is an unusually high proportion of can (41.1%) in the textbooks. The results on different meanings shows that will, would and must are the most problematic. For example, for will, the textbooks contain 20% more occurrences of 'volition' and 20% less of 'prediction' than those in BNCS2014. Regarding co-occurring structures, the textbooks over-represented the structure 'modal +do' across the nine modal verbs. Another major finding is that the structure of 'modal +have done' that frequently co-occur with could, would, should, and must is underused in textbooks. Besides, these four modal verbs are the most difficult for learners, as the error analysis shows. This study demonstrates how the synergy of native and learner corpora can be harnessed to improve EFL textbook presentation of modal verbs in a way that textbooks can provide not only authentic language used in natural discourse but also appropriate design tailed for the needs of target learners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=English%20as%20Foreign%20Language" title="English as Foreign Language">English as Foreign Language</a>, <a href="https://publications.waset.org/abstracts/search?q=EFL%20textbooks" title=" EFL textbooks"> EFL textbooks</a>, <a href="https://publications.waset.org/abstracts/search?q=learner%20corpus" title=" learner corpus"> learner corpus</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20verbs" title=" modal verbs"> modal verbs</a>, <a href="https://publications.waset.org/abstracts/search?q=native%20corpus" title=" native corpus"> native corpus</a> </p> <a href="https://publications.waset.org/abstracts/109495/the-use-of-corpora-in-improving-modal-verb-treatment-in-english-as-foreign-language-textbooks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109495.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">143</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> Development and Implementation of a Business Technology Program Based on Techniques for Reusing Water in a Colombian Company</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Miguel%20A.%20Jimenez%20Barros">Miguel A.

Water consumption has three main uses, municipal (common use), agricultural and industrial where the latter consumes a minimum percentage (around 20% of the total consumption). Awareness on world water scarcity, a Colombian company responsible for generation of massive consumption products, decided to implement politics and techniques for water treatment, recycling, and reuse. The project consisted in a business technology program that permits a better use of wastewater caused by production operations. This approach reduces the potable water consumption, generates better conditions of water in the sewage dumps, generates a positive environmental impact for the region, and is a reference model in national and international levels. In order to achieve the objective, a process flow diagram was used in order to define the industrial processes that required potable water. This strategy allowed the industry to determine a water reuse plan at the operational level without affecting the requirements associated with the manufacturing process and even more, to support the activities developed in administrative buildings. Afterwards, the company made an evaluation and selection of the chemical and biological processes required for water reuse, in compliance with the Colombian Law. The implementation of the business technology program optimized the water use and recirculation rate up to 70%, accomplishing an important reduction of the regional environmental impact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-reactor" title="bio-reactor">bio-reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=potable%20water" title=" potable water"> potable water</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20osmosis" title=" reverse osmosis"> reverse osmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20treatment" title=" water treatment"> water treatment</a> </p> <a href="https://publications.waset.org/abstracts/69256/development-and-implementation-of-a-business-technology-program-based-on-techniques-for-reusing-water-in-a-colombian-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69256.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">235</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> Music Educators for Peace: Synchronizing Music and Pedagogical Experiences to Re-Build Social Fabric in Colombia's Post-Conflict</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julian%20Dario%20Castro%20Cifuentes">Julian Dario Castro Cifuentes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Colombia, the armed conflict has lasted for more than sixty years bringing poverty, internal displacement of people, deaths from both government and insurgent forces and other violence-related problems that has damaged its social fabric. In 2016, the peace process between the Colombian government and the FARC rebels brought the possibility of ending this war and a new set of challenges to Colombian society in order to achieve pacific coexistence and reconciliation. In this scenario, there have been different efforts from diverse social actors in order to build peace and reconciliation mainly within the victims of the armed conflict. In the case of music, there have been multiple programs for social transformation through music and pedagogical experiences. Nevertheless, the need to strengthen this initiative by giving ‘peace building oriented’ pedagogical tools to the musicians that lead this experiences and understanding which aspects make this practices ‘musically meaningful’, has been recognized. For this reason, the purpose of this study is to discuss the convergences and divergences of music, and educational experiences applied to peacebuilding in the context of Colombia’s post-conflict. In this research, the hermeneutic phenomenology paradigm is applied in a case study of a peace building music education experience in the department of Nariño, Colombia articulated with the program ‘Manos a la Paz’. Two particular experiences, one on musical practice and another on music education are taken as a unit of analysis to understand its essence and structure in order to find ways to articulate efforts in peace building actions from music. This study shows how the existent gap between music experience and its subjacent pedagogical knowledge, can be reduced through deconstruction of the music and pedagogical experience. The ‘Manos a la Paz’ program showed how a peace building approach to music education can make major contributions to Pacific Coexistence and Reconciliation in Colombia’s Post-Conflict. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=music%20education" title="music education">music education</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20for%20peace" title=" music for peace"> music for peace</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20pedagogy" title=" music pedagogy"> music pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=peace%20building" title=" peace building"> peace building</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20fabric" title=" social fabric"> social fabric</a> </p> <a href="https://publications.waset.org/abstracts/70421/music-educators-for-peace-synchronizing-music-and-pedagogical-experiences-to-re-build-social-fabric-in-colombias-post-conflict" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70421.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">229</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> Optimal Pricing Based on Real Estate Demand Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vanessa%20Kummer">Vanessa Kummer</a>, <a href="https://publications.waset.org/abstracts/search?q=Maik%20Meusel"> Maik Meusel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Real estate demand estimates are typically derived from transaction data. However, in regions with excess demand, transactions are driven by supply and therefore do not indicate what people are actually looking for. To estimate the demand for housing in Switzerland, search subscriptions from all important Swiss real estate platforms are used. These data do, however, suffer from missing information—for example, many users do not specify how many rooms they would like or what price they would be willing to pay. In economic analyses, it is often the case that only complete data is used. Usually, however, the proportion of complete data is rather small which leads to most information being neglected. Also, the data might have a strong distortion if it is complete. In addition, the reason that data is missing might itself also contain information, which is however ignored with that approach. An interesting issue is, therefore, if for economic analyses such as the one at hand, there is an added value by using the whole data set with the imputed missing values compared to using the usually small percentage of complete data (baseline). Also, it is interesting to see how different algorithms affect that result. The imputation of the missing data is done using unsupervised learning. Out of the numerous unsupervised learning approaches, the most common ones, such as clustering, principal component analysis, or neural networks techniques are applied. By training the model iteratively on the imputed data and, thereby, including the information of all data into the model, the distortion of the first training set—the complete data—vanishes. In a next step, the performances of the algorithms are measured. This is done by randomly creating missing values in subsets of the data, estimating those values with the relevant algorithms and several parameter combinations, and comparing the estimates to the actual data. After having found the optimal parameter set for each algorithm, the missing values are being imputed. Using the resulting data sets, the next step is to estimate the willingness to pay for real estate. This is done by fitting price distributions for real estate properties with certain characteristics, such as the region or the number of rooms. Based on these distributions, survival functions are computed to obtain the functional relationship between characteristics and selling probabilities. Comparing the survival functions shows that estimates which are based on imputed data sets do not differ significantly from each other; however, the demand estimate that is derived from the baseline data does. This indicates that the baseline data set does not include all available information and is therefore not representative for the entire sample. Also, demand estimates derived from the whole data set are much more accurate than the baseline estimation. Thus, in order to obtain optimal results, it is important to make use of all available data, even though it involves additional procedures such as data imputation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demand%20estimate" title="demand estimate">demand estimate</a>, <a href="https://publications.waset.org/abstracts/search?q=missing-data%20imputation" title=" missing-data imputation"> missing-data imputation</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20estate" title=" real estate"> real estate</a>, <a href="https://publications.waset.org/abstracts/search?q=unsupervised%20learning" title=" unsupervised learning"> unsupervised learning</a> </p> <a href="https://publications.waset.org/abstracts/63354/optimal-pricing-based-on-real-estate-demand-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63354.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">285</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> Industrial Prototype for Hydrogen Separation and Purification: Graphene Based-Materials Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Alfredo%20Guevara%20Carrio">Juan Alfredo Guevara Carrio</a>, <a href="https://publications.waset.org/abstracts/search?q=Swamy%20Toolahalli%20Thipperudra"> Swamy Toolahalli Thipperudra</a>, <a href="https://publications.waset.org/abstracts/search?q=Riddhi%20Naik%20Dharmeshbhai"> Riddhi Naik Dharmeshbhai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Graniero%20Echeverrigaray"> Sergio Graniero Echeverrigaray</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Vitorio%20Emiliano"> Jose Vitorio Emiliano</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Helio%20Castro"> Antonio Helio Castro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to advance the hydrogen economy, several industrial sectors can potentially benefit from the trillions of stimulus spending for post-coronavirus. Blending hydrogen into natural gas pipeline networks has been proposed as a means of delivering it during the early market development phase, using separation and purification technologies downstream to extract the pure H₂ close to the point of end-use. This first step has been mentioned around the world as an opportunity to use existing infrastructures for immediate decarbonisation pathways. Among current technologies used to extract hydrogen from mixtures in pipelines or liquid carriers, membrane separation can achieve the highest selectivity. The most efficient approach for the separation of H₂ from other substances by membranes is offered from the research of 2D layered materials due to their exceptional physical and chemical properties. Graphene-based membranes, with their distribution of pore sizes in nanometers and angstrom range, have shown fundamental and economic advantages over other materials. Their combination with the structure of ceramic and geopolymeric materials enabled the synthesis of nanocomposites and the fabrication of membranes with long-term stability and robustness in a relevant range of physical and chemical conditions. Versatile separation modules have been developed for hydrogen separation, which adaptability allows their integration in industrial prototypes for applications in heavy transport, steel, and cement production, as well as small installations at end-user stations of pipeline networks. The developed membranes and prototypes are a practical contribution to the technological challenge of supply pure H₂ for the mentioned industries as well as hydrogen energy-based fuel cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphene%20nano-composite%20membranes" title="graphene nano-composite membranes">graphene nano-composite membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20separation%20and%20purification" title=" hydrogen separation and purification"> hydrogen separation and purification</a>, <a href="https://publications.waset.org/abstracts/search?q=separation%20modules" title=" separation modules"> separation modules</a>, <a href="https://publications.waset.org/abstracts/search?q=indsutrial%20prototype" title=" indsutrial prototype"> indsutrial prototype</a> </p> <a href="https://publications.waset.org/abstracts/127504/industrial-prototype-for-hydrogen-separation-and-purification-graphene-based-materials-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127504.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">159</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> Integrated Genetic-A* Graph Search Algorithm Decision Model for Evaluating Cost and Quality of School Renovation Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Ching%20Cheng">Yu-Ching Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Kai%20Juan"> Yi-Kai Juan</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Castro"> Daniel Castro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy consumption of buildings has been an increasing concern for researchers and practitioners in the last decade. Sustainable building renovation can reduce energy consumption and carbon dioxide emissions; meanwhile, it also can extend existing buildings useful life and facilitate environmental sustainability while providing social and economic benefits to the society. School buildings are different from other designed spaces as they are more crowded and host the largest portion of daily activities and occupants. Strategies that focus on reducing energy use but also improve the students’ learning environment becomes a significant subject in sustainable school buildings development. A decision model is developed in this study to solve complicated and large-scale combinational, discrete and determinate problems such as school renovation projects. The task of this model is to automatically search for the most cost-effective (lower cost and higher quality) renovation strategies. In this study, the search process of optimal school building renovation solutions is by nature a large-scale zero-one programming determinate problem. A* is suitable for solving deterministic problems due to its stable and effective search process, and genetic algorithms (GA) provides opportunities to acquire global optimal solutions in a short time via its indeterminate search process based on probability. These two algorithms are combined in this study to consider trade-offs between renovation cost and improved quality, this decision model is able to evaluate current school environmental conditions and suggest an optimal scheme of sustainable school buildings renovation strategies. Through adoption of this decision model, school managers can overcome existing limitations and transform school buildings into spaces more beneficial to students and friendly to the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20model" title="decision model">decision model</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20buildings" title=" school buildings"> school buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20renovation" title=" sustainable renovation"> sustainable renovation</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=A%2A%20search%20algorithm" title=" A* search algorithm"> A* search algorithm</a> </p> <a href="https://publications.waset.org/abstracts/97308/integrated-genetic-a-graph-search-algorithm-decision-model-for-evaluating-cost-and-quality-of-school-renovation-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97308.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">57</span> Occurrence of Pharmaceutical Compounds in an Urban Lake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20D.%20Villanueva">J.

These pharmaceuticals were measured in Napindan Lake, Philippines. This lake is not only a major tributary of the Pasig River (an estuary) and Laguna Lake (freshwater). It also joins these two important surface waters of the National Capital Region. Pharmaceutical compounds such as Atenolol, Carbamazepine, and two other over the counter medicines: Cetirizine, and Ibuprofen were measured in Napindan Lake. Atenolol is a beta blocker that helps in lowering hypertensions. Carbamazepine is an anticonvulsant used as treatment for epilepsy and neuropathic pain. Cetirizine is an antihistamine that can relieve allergies. Ibuprofen is a non-steroidal anti-inflammatory drug normally used to relieve pains. Three different climatological conditions with corresponding hydro physico chemical characteristics were considered. First, was during a dry season with a simultaneous dredging. Second was during a transition period from dry to wet season. Finally, the third was during a continuous wet event. Based from the results of the study, most of these pharmaceuticals can be found in Napindan Lake. This is a proof that these pharmaceutical compounds are being released to a natural surface water. Even though climatological conditions were different, concentrations of these pharmaceuticals can still be detected. This implies that there is an incessant supply of these pharmaceutical compounds in Napindan Lake. Chronic exposure to these compounds even at low concentrations can lead to possible environmental and health risks. Given this information and since consistent occurrence of these compounds can be expected, the main challenge, at present, is on how to control the sources of these pharmaceutical compounds. Primarily, there is a need to manage the disposal of the pharmaceutical compounds. Yet, the main question is how to? This study would like to present the challenges and institutional roles in helping manage the pharmaceutical disposals in a developing country like the Philippines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atenolol" title="atenolol">atenolol</a>, <a href="https://publications.waset.org/abstracts/search?q=carbamazepine" title=" carbamazepine"> carbamazepine</a>, <a href="https://publications.waset.org/abstracts/search?q=cetirizine" title=" cetirizine"> cetirizine</a>, <a href="https://publications.waset.org/abstracts/search?q=ibuprofen" title=" ibuprofen"> ibuprofen</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20roles" title=" institutional roles"> institutional roles</a>, <a href="https://publications.waset.org/abstracts/search?q=Napindan%20lake" title=" Napindan lake"> Napindan lake</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceutical%20compound%20disposal%20management" title=" pharmaceutical compound disposal management"> pharmaceutical compound disposal management</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20water" title=" surface water"> surface water</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20lake" title=" urban lake"> urban lake</a> </p> <a href="https://publications.waset.org/abstracts/122704/occurrence-of-pharmaceutical-compounds-in-an-urban-lake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122704.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">162</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> Sustainable Membranes Based on 2D Materials for H₂ Separation and Purification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20A.%20G.%20Carrio">Juan A.

The extensive deployment of hydrogen production, purification and transport infrastructures still represents significant challenges. Independent of the production process, the hydrogen generally is mixed with light hydrocarbons and other undesirable gases that need to be removed to obtain H₂ with the required purity for end applications. In this context, membranes are one of the simplest, most attractive, sustainable, and performant technologies enabling hydrogen separation and purification. They demonstrate high separation efficiencies and low energy consumption levels in operation, which is a significant leap compared to current energy-intensive options technologies. The unique characteristics of 2D laminates have given rise to a diversity of research on their potential applications in separation systems. Specifically, it is already known in the scientific literature that graphene oxide-based membranes present the highest reported selectivity of H₂ over other gases. This work explores the potential of a new type of 2D materials-based membranes in separating H₂ from CO₂ and CH₄. We have developed nanostructured composites based on 2D materials that have been applied in the fabrication of membranes to maximise H₂ selectivity and permeability, for different gas mixtures, by adjusting the membranes' characteristics. Our proprietary technology does not depend on specific porous substrates, which allows its integration in diverse separation modules with different geometries and configurations, looking to address the technical performance required for industrial applications and economic viability. The tuning and precise control of the processing parameters allowed us to control the thicknesses of the membranes below 100 nanometres to provide high permeabilities. Our results for the selectivity of new nanostructured 2D materials-based membranes are in the range of the performance reported in the available literature around 2D materials (such as graphene oxide) applied to hydrogen purification, which validates their use as one of the most promising next-generation hydrogen separation and purification solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=membranes" title="membranes">membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=2D%20materials" title=" 2D materials"> 2D materials</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20purification" title=" hydrogen purification"> hydrogen purification</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a> </p> <a href="https://publications.waset.org/abstracts/161099/sustainable-membranes-based-on-2d-materials-for-h2-separation-and-purification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161099.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">134</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> Nutritional Impact in Patients Who Underwent Sleeve-Type Bariatric Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Mattos">Melissa Mattos</a>, <a href="https://publications.waset.org/abstracts/search?q=Camila%20Lima"> Camila Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibraim%20Castro"> Ibraim Castro</a>, <a href="https://publications.waset.org/abstracts/search?q=Augusto%20Carioca"> Augusto Carioca</a>, <a href="https://publications.waset.org/abstracts/search?q=Saulo%20Magalh%C3%A3es"> Saulo Magalhães</a>, <a href="https://publications.waset.org/abstracts/search?q=Paula%20Freitas"> Paula Freitas</a>, <a href="https://publications.waset.org/abstracts/search?q=Keciany%20Oliveira"> Keciany Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Obesity is a chronic, multifactorial, relapsing disease that has increased dramatically over the years. Its control is considered a public health issue, and more and more treatments and interventions are being studied to reduce its prevalence. When interventions in lifestyle and the use of drugs do not generate lasting results, bariatric procedures emerge as a resource for obesity control. The main guidelines for the treatment of obesity emphasize the need for pre-procedure and post-procedure nutritional monitoring to avoid nutritional deficiencies that may occur. The individual who undergoes bariatric surgery needs to understand the changes that will be necessary for life in view of the intense anatomical and metabolic changes that result from surgical techniques. To assess the nutritional profile of patients who undergo bariatric surgery, we analyzed data from the medical records of all people who underwent sleeve-type bariatric surgery from January to June 2022 at a clinic in the City of Fortaleza. 38 patients were analyzed, 32 women and 6 men in the pre-surgical period, 6 and 12 months after surgery. The data showed an average weight loss of 24.45% at 6 months and 30.85% at 12 months, with a reduction of 21.32% and 30.41%, respectively, in the fat percentage, also indicating that 13.15% used drugs for weight loss during this period, leading to reflection on the isolated long-term efficacy of bariatric surgery, requiring multidisciplinary follow-up for a change in lifestyle. Only 12 individuals, corresponding to 31.57%, reached eutrophic BMI 12 months after surgery, 20 individuals remained overweight, corresponding to 52.63% of the sample, and 6 individuals (15.78%) remained in the BMI obese class I. As for body composition, there was a 52.39% reduction in fat mass and a 12.82% reduction in muscle mass, and 21% of individuals underwent cholecystectomy. Sleeve-type bariatric surgery promoted significant weight loss after 1 year of the procedure, with a reduction in body fat percentage and fat mass. Most patients were still overweight and had a significant reduction in muscle mass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bariatric%20surgery" title="bariatric surgery">bariatric surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=sleeve%20gastrectomy" title=" sleeve gastrectomy"> sleeve gastrectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=sleeve" title=" sleeve"> sleeve</a> </p> <a href="https://publications.waset.org/abstracts/172261/nutritional-impact-in-patients-who-underwent-sleeve-type-bariatric-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172261.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">68</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> Chemical Composition of Volatiles Emitted from Ziziphus jujuba Miller Collected during Different Growth Stages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rose%20Vanessa%20Bandeira%20Reidel">Rose Vanessa Bandeira Reidel</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernardo%20Melai"> Bernardo Melai</a>, <a href="https://publications.waset.org/abstracts/search?q=Pier%20Luigi%20Cioni"> Pier Luigi Cioni</a>, <a href="https://publications.waset.org/abstracts/search?q=Luisa%20Pistelli"> Luisa Pistelli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ziziphus jujuba Miller is a common species of the Ziziphus genus (Rhamnaceae family) native to the tropics and subtropics known for its edible fruits, fresh consumed or used in healthy food, as flavoring and sweetener. Many phytochemicals and biological activities are described for this species. In this work, the aroma profiles emitted in vivo by whole fresh organs (leaf, bud flower, flower, green and red fruits) were analyzed separately by mean of solid phase micro-extraction (SPME) coupled with gas chromatography mass spectrometry (GC-MS). The emitted volatiles from different plant parts were analysed using Supelco SPME device coated with polydimethylsiloxane (PDMS, 100µm). Fresh plant material was introduced separately into a glass conical flask and allowed to equilibrate for 20 min. After the equilibration time, the fibre was exposed to the headspace for 15 min at room temperature, the fibre was re-inserted into the needle and transferred to the injector of the CG and CG-MS system, where the fibre was desorbed. All the data were submitted to multivariate statistical analysis, evidencing many differences amongst the selected plant parts and their developmental stages. A total of 144 compounds were identified corresponding to 94.6-99.4% of the whole aroma profile of jujube samples. Sesquiterpene hydrocarbons were the main chemical class of compounds in leaves also present in similar percentage in flowers and bud flowers where (E, E)-α-farnesene was the main constituent in all cited plant parts. This behavior can be due to a protection mechanism against pathogens and herbivores as well as resistance to abiotic factors. The aroma of green fruits was characterized by high amount of perillene while the red fruits release a volatile blend mainly constituted by different monoterpenes. The terpenoid emission of flesh fruits has important function in the interaction with animals including attraction of seed dispersers and it is related to a good quality of fruits. This study provides for the first time the chemical composition of the volatile emission from different Ziziphus jujuba organs. The SPME analyses of the collected samples showed different patterns of emission and can contribute to understand their ecological interactions and fruit production management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rhamnaceae" title="Rhamnaceae">Rhamnaceae</a>, <a href="https://publications.waset.org/abstracts/search?q=aroma%20profile" title=" aroma profile"> aroma profile</a>, <a href="https://publications.waset.org/abstracts/search?q=jujube%20organs" title=" jujube organs"> jujube organs</a>, <a href="https://publications.waset.org/abstracts/search?q=HS-SPME" title=" HS-SPME"> HS-SPME</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a> </p> <a href="https://publications.waset.org/abstracts/70950/chemical-composition-of-volatiles-emitted-from-ziziphus-jujuba-miller-collected-during-different-growth-stages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70950.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">256</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> Exploring the Facets of Sexuality among Older Adults</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vivienne%20Cloude%20C.%20Bersabe">Vivienne Cloude C.

This research was conducted to highlight the need for nurses to incorporate sexuality in their care of older adults. Research Objectives: To measure the levels of older adults’ sexual desire, sexual behavior, and sexual intimacy and relate them to sex, living arrangement, educational level, and presence of chronic illness, whether with or without treatment. Methods: This study is of quantitative descriptive design that utilized purposive sampling. 400 older adults of Baguio City participated. The study used a 30 point researcher-made questionnaire, one-on-one interview and focused group discussion to gather data. Data were treated using weighted mean, t-test, F-test, and Scheffe's test. Results and Conclusions: The overall findings revealed that Filipino older adults have a low level of sexuality expressed by the participants’ sexual desire, behavior, and intimacy. Males have significantly higher level of sexual desire, behavior, and intimacy. Living arrangement does not seem to influence the level of sexuality in all its 3 facets. Sexual desire was significantly higher among those with tertiary education and without chronic illness. Recommendation: It is recommended that nurses carry out their assessment of clients to include the exploration of their sexuality especially the older adults. A similar study may be done to explore other variables like demographic location, i.e., rural or urban setting; socio-cultural factors; and functional performance status. It is also recommended that a similar study may be done exploring the different facets of sexuality among homosexual older persons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geriatrics" title="geriatrics">geriatrics</a>, <a href="https://publications.waset.org/abstracts/search?q=older%20adults" title=" older adults"> older adults</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippines" title=" Philippines"> Philippines</a>, <a href="https://publications.waset.org/abstracts/search?q=sexuality" title=" sexuality"> sexuality</a> </p> <a href="https://publications.waset.org/abstracts/56008/exploring-the-facets-of-sexuality-among-older-adults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56008.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">272</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> Satellite Images to Determine Levels of Fire Severity in a Native Chilean Forest: Assessing the Responses of Soil Mesofauna Diversity to a Fire Event</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Morales">Carolina Morales</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Castro-Huerta"> Ricardo Castro-Huerta</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20A.%20Mundaca"> Enrique A.

Edaphic organisms are highly sensitive to soil disturbances, which normally causes changes in the composition and abundance of such organisms. Fire is known to be a disturbing factor since it affects the physical, chemical and biological properties of the soil and the whole ecosystem. During the summer (December-March) of 2017, Chile suffered the major fire events recorded in its modern history, which affected a vast area and a number of ecosystem types. The objective of this study was first to use remote sensing satellite images and GIS (Geographic Information Systems) to assess and identify levels of fire severity in disturbed areas and to compare the responses of the soil mesofauna diversity among such areas. We identified four areas (treatments) with an ascending level of severity, namely: mild, medium, high severity, and free of fire. A non-affected patch of forest was established as a control. Three samples from each treatment were collected in the form of a soil cube (10x10x10 cm). Edaphic mesofauna was obtained from each sample through the Berlese-Tullgren funnel method. Collected specimens were quantified and identified, using the RTU (Recognisable Taxonomic Unit) criterion. Diversity was analysed using inferential statistics to compare Simpson and Shannon-Wiener indexes across treatments. As predicted, the unburned forest patch (control) exhibited higher diversity values than the treatments. Significantly higher diversity values were recorded in those treatments subjected to lower fire severity. We conclude that remote sensing zoning is an adequate tool to identify different levels of fire severity and that an edaphic mesofauna is a group of organisms that qualify as good bioindicators for monitoring soil recovery after fire events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioindicator" title="bioindicator">bioindicator</a>, <a href="https://publications.waset.org/abstracts/search?q=Chile" title=" Chile"> Chile</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20severity%20level" title=" fire severity level"> fire severity level</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a> </p> <a href="https://publications.waset.org/abstracts/92135/satellite-images-to-determine-levels-of-fire-severity-in-a-native-chilean-forest-assessing-the-responses-of-soil-mesofauna-diversity-to-a-fire-event" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92135.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">160</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> Social Mentoring: Towards Formal and Informal Deployment in the Structures of the Social and Solidarity Economy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vanessa%20Casadella">Vanessa Casadella</a>, <a href="https://publications.waset.org/abstracts/search?q=Mourad%20Chouki"> Mourad Chouki</a>, <a href="https://publications.waset.org/abstracts/search?q=Agn%C3%A8s%20Ceccarelli"> Agnès Ceccarelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Sofiane%20Tahi"> Sofiane Tahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mentoring is positioned in an interpersonal and intergenerational perspective, serving the transmission of interpersonal skills and organizational culture. It echoes orientation, project, self-actualization, guidance, transmission, and filiation. It is available using a formal or informal approach. The formal dimension refers to a privileged relationship between a senior and a junior. Informal mentoring is unplanned and emerges naturally between two people who choose each other. However, it remains more difficult to understand. To study the link between formal and informal mentoring and to define the notion of “social” mentoring, we conducted a qualitative study of an exploratory nature with around ten SSE organizations located in the southeast region of Tunisia. The wealth of this territory has pushed residents to found SSE organizations with a view to creating jobs but also to preserving traditions and preserving nature. These organizations developed spontaneously to solve various local problems, such as the revitalization of deserted rural areas, environmental degradation, and the reskilling and professional reintegration of people marginalized in the labor market. This research, based on semi-structured interviews in order to obtain exhaustive and sensitive data, involves an interview guide with few questions mobilized to let the respondents, leaders of the different structures, express themselves freely. The guide includes questions on activities, methods of sharing knowledge, and difficulties in understanding between stakeholders. The interviews, lasting 30 to 60 minutes, were recorded using a dictaphone and then transcribed in full. The results are as follows: 1. We see two iterative mentoring loops. A first loop can be considered a type of formal mentoring. It highlights the support organized (in the form of training) by social enterprises with the aim of developing the autonomy, know-how, and interpersonal skills of members. A second loop concerns informal mentoring. This is non-formalized support provided by members or with other members of the entourage. This informal mentoring is mainly based on the observation of good practices and learning by doing. 2. We notice an intersection between the two loops. If the first loop is not done, the second will not take place. The knowledge acquired in the first loop is used to feed the second. 3. We note a form of reluctance on the part of some members to share their knowledge for reasons of competition. Ultimately, we retain the notion of “social” mentoring as a hybridization of formal and informal mentoring while dimensioning the “social” perspective by emphasizing the reciprocal character, solidarity, confidence, and trust between the mentor and the mentee. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20innovation" title="social innovation">social innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20mentoring" title=" social mentoring"> social mentoring</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20and%20solidarity%20economy" title=" social and solidarity economy"> social and solidarity economy</a>, <a href="https://publications.waset.org/abstracts/search?q=informal%20mentoring" title=" informal mentoring"> informal mentoring</a> </p> <a href="https://publications.waset.org/abstracts/177541/social-mentoring-towards-formal-and-informal-deployment-in-the-structures-of-the-social-and-solidarity-economy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177541.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">54</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> Beyond Information Failure and Misleading Beliefs in Conditional Cash Transfer Programs: A Qualitative Account of Structural Barriers Explaining Why the Poor Do Not Invest in Human Capital in Northern Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Fernandez%20de%20Castro">Francisco Fernandez de Castro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Conditional Cash Transfer (CCT) model gives monetary transfers to beneficiary families on the condition that they take specific education and health actions. According to the economic rationale of CCTs the poor need incentives to invest in their human capital because they are trapped by a lack of information and misleading beliefs. If left to their own decision, the poor will not be able to choose what is in their best interests. The basic assumption of the CCT model is that the poor need incentives to take care of their own education and health-nutrition. Due to the incentives (income cash transfers and conditionalities), beneficiary families are supposed to attend doctor visits and health talks. Children would stay in the school. These incentivized behaviors would produce outcomes such as better health and higher level of education, which in turn will reduce poverty. Based on a grounded theory approach to conduct a two-year period of qualitative data collection in northern Mexico, this study shows that this explanation is incomplete. In addition to the information failure and inadequate beliefs, there are structural barriers in everyday life of households that make health-nutrition and education investments difficult. In-depth interviews and observation work showed that the program takes for granted local conditions in which beneficiary families should fulfill their co-responsibilities. Data challenged the program’s assumptions and unveiled local obstacles not contemplated in the program’s design. These findings have policy and research implications for the CCT agenda. They bring elements for late programming due to the gap between the CCT strategy as envisioned by policy designers, and the program that beneficiary families experience on the ground. As for research consequences, these findings suggest new avenues for scholarly work regarding the causal mechanisms and social processes explaining CCT outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conditional%20cash%20transfers" title="conditional cash transfers">conditional cash transfers</a>, <a href="https://publications.waset.org/abstracts/search?q=incentives" title=" incentives"> incentives</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty" title=" poverty"> poverty</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20barriers" title=" structural barriers"> structural barriers</a> </p> <a href="https://publications.waset.org/abstracts/92468/beyond-information-failure-and-misleading-beliefs-in-conditional-cash-transfer-programs-a-qualitative-account-of-structural-barriers-explaining-why-the-poor-do-not-invest-in-human-capital-in-northern-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92468.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">113</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> Multi-Scale Modeling of Ti-6Al-4V Mechanical Behavior: Size, Dispersion and Crystallographic Texture of Grains Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatna%20Benmessaoud">Fatna Benmessaoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Cheikh"> Mohammed Cheikh</a>, <a href="https://publications.waset.org/abstracts/search?q=Vencent%20Velay"> Vencent Velay</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanessa%20Vidal"> Vanessa Vidal</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Rezai-Aria"> Farhad Rezai-Aria</a>, <a href="https://publications.waset.org/abstracts/search?q=Christine%20Boher"> Christine Boher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ti-6Al-4V titanium alloy is one of the most widely used materials in aeronautical and aerospace industries. Because of its high specific strength, good fatigue, and corrosion resistance, this alloy is very suitable for moderate temperature applications. At room temperature, Ti-6Al-4V mechanical behavior is generally controlled by the behavior of alpha phase (beta phase percent is less than 8%). The plastic strain of this phase notably based on crystallographic slip can be hindered by various obstacles and mechanisms (crystal lattice friction, sessile dislocations, strengthening by solute atoms and grain boundaries…). The grains aspect of alpha phase (its morphology and texture) and the nature of its crystallographic lattice (which is hexagonal compact) give to plastic strain heterogeneous, discontinuous and anisotropic characteristics at the local scale. The aim of this work is to develop a multi-scale model for Ti-6Al-4V mechanical behavior using crystal plasticity approach; this multi-scale model is used then to investigate grains size, dispersion of grains size, crystallographic texture and slip systems activation effects on Ti-6Al-4V mechanical behavior under monotone quasi-static loading. Nine representative elementary volume (REV) are built for taking into account the physical elements (grains size, dispersion and crystallographic) mentioned above, then boundary conditions of tension test are applied. Finally, simulation of the mechanical behavior of Ti-6Al-4V and study of slip systems activation in alpha phase is reported. The results show that the macroscopic mechanical behavior of Ti-6Al-4V is strongly linked to the active slip systems family (prismatic, basal or pyramidal). The crystallographic texture determines which family of slip systems can be activated; therefore it gives to the plastic strain a heterogeneous character thus an anisotropic macroscopic mechanical behavior of Ti-6Al-4V alloy modeled. The grains size influences also on mechanical proprieties of Ti-6Al-4V, especially on the yield stress; by decreasing of the grain size, the yield strength increases. Finally, the grains' distribution which characterizes the morphology aspect (homogeneous or heterogeneous) gives to the deformation fields distribution enough heterogeneity because the crystallographic slip is easier in large grains compared to small grains, which generates a localization of plastic deformation in certain areas and a concentration of stresses in others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-scale%20modeling" title="multi-scale modeling">multi-scale modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=Ti-6Al-4V%20alloy" title=" Ti-6Al-4V alloy"> Ti-6Al-4V alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=crystal%20plasticity" title=" crystal plasticity"> crystal plasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=grains%20size" title=" grains size"> grains size</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallographic%20texture" title=" crystallographic texture"> crystallographic texture</a> </p> <a href="https://publications.waset.org/abstracts/86843/multi-scale-modeling-of-ti-6al-4v-mechanical-behavior-size-dispersion-and-crystallographic-texture-of-grains-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86843.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">157</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> Emotional Processing Difficulties in Recovered Anorexia Nervosa Patients: State or Trait</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Telma%20Fontao%20de%20Castro">Telma Fontao de Castro</a>, <a href="https://publications.waset.org/abstracts/search?q=Kylee%20Miller"> Kylee Miller</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Xavier%20Ara%C3%BAjo"> Maria Xavier Araújo</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Brandao"> Isabel Brandao</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Torres"> Sandra Torres</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: There is a dearth of research investigating the long-term emotional functioning of individuals recovered from anorexia nervosa (AN). This 15-year longitudinal study aimed to examine whether difficulties in cognitive processing of emotions persisted after long-term AN recovery and its link to anxiety and depression. Method: Twenty-four females, who were tested longitudinally during their acute and recovered AN phases, and 24 healthy control (HC) women, were screened for anxiety, depression, alexithymia, and emotion regulation difficulties (ER; only assessed in recovery phase). Results: Anxiety, depression, and alexithymia levels decreased significantly with AN recovery. However, scores on anxiety and difficulty in identifying feelings (alexithymia factor) remained high when compared to the HC group. Scores on emotion regulation difficulties were also lower in HC group. The abovementioned differences between AN recovered group and HC group in difficulties in identifying and accepting feelings and lack of emotional clarity were no longer present when the effect of anxiety and depression was controlled. Conclusions: Findings suggest that emotional dysfunction tends to decrease in AN recovered phase. However, using an HC group as a reference, we conclude that several emotional difficulties are still increased after long-term AN recovery, in particular, limited access to emotion regulation strategies, and difficulty controlling impulses and engaging in goal-directed behavior, thus suggesting to be a trait vulnerability. In turn, competencies related to emotional clarity and acceptance of emotional responses seem to be state-dependent phenomena linked to anxiety and depression. In sum, managing emotions remains a challenge for individuals recovered from AN. Under this circumstance, maladaptive eating behavior can serve as an affect regulatory function, increasing the risk of relapse. Emotional education and stabilization of depressive and anxious symptomatology after recovery emerge as an important avenue to protect from long-term AN relapse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alexithymia" title="alexithymia">alexithymia</a>, <a href="https://publications.waset.org/abstracts/search?q=anorexia%20nervosa" title=" anorexia nervosa"> anorexia nervosa</a>, <a href="https://publications.waset.org/abstracts/search?q=emotion%20recognition" title=" emotion recognition"> emotion recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=emotion%20regulation" title=" emotion regulation"> emotion regulation</a> </p> <a href="https://publications.waset.org/abstracts/130888/emotional-processing-difficulties-in-recovered-anorexia-nervosa-patients-state-or-trait" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130888.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">123</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">47</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">371</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> Medial Temporal Tau Predicts Memory Decline in Cognitively Unimpaired Elderly</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angela%20T.%20H.%20Kwan">Angela T.

[¹⁸F]-MK-6420 is a high affinity positron emission tomography (PET) tracer that quantifies tau neurofibrillary tangles, but its ability to predict cognitive changes associated with early AD symptoms, such as memory decline, is unclear. Here, we assess the prognostic accuracy of baseline [18F]-MK-6420 tau PET for predicting longitudinal memory decline in asymptomatic elderly individuals. In a longitudinal observational study, we evaluated a cohort of cognitively normal elderly participants (n = 111) from the Translational Biomarkers in Aging and Dementia (TRIAD) study (data collected between October 2017 and July 2020, with a follow-up period of 12 months). All participants underwent tau PET with [¹⁸F]-MK-6420 and Aβ PET with [¹⁸F]-AZD-4694. The exclusion criteria included the presence of head trauma, stroke, or other neurological disorders. There were 111 eligible participants who were chosen based on the availability of Aβ PET, tau PET, magnetic resonance imaging (MRI), and APOEε4 genotyping. Among these participants, the mean (SD) age was 70.1 (8.6) years; 20 (18%) were tau PET positive, and 71 of 111 (63.9%) were women. A significant association between baseline Braak I-II [¹⁸F]-MK-6240 SUVR positivity and change in composite memory score was observed at the 12-month follow-up, after correcting for age, sex, and years of education (Logical Memory and RAVLT, standardized beta = -0.52 (-0.82-0.21), p < 0.001, for dichotomized tau PET and -1.22 (-1.84-(-0.61)), p < 0.0001, for continuous tau PET). Moderate cognitive decline was observed for A+T+ over the follow-up period, whereas no significant change was observed for A-T+, A+T-, and A-T-, though it should be noted that the A-T+ group was small.Our results indicate that baseline tau neurofibrillary tangle pathology is associated with longitudinal changes in memory function, supporting the use of [¹⁸F]-MK-6420 PET to predict the likelihood of asymptomatic elderly individuals experiencing future memory decline. Overall, [¹⁸F]-MK-6420 PET is a promising tool for predicting memory decline in older adults without cognitive impairment at baseline. This is of critical relevance as the field is shifting towards a biological model of AD defined by the aggregation of pathologic tau. Therefore, early detection of tau pathology using [¹⁸F]-MK-6420 PET provides us with the hope that living patients with AD may be diagnosed during the preclinical phase before it is too late. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alzheimer%E2%80%99s%20disease" title="alzheimer’s disease">alzheimer’s disease</a>, <a href="https://publications.waset.org/abstracts/search?q=braak%20I-II" title=" braak I-II"> braak I-II</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vivo%20biomarkers" title=" in vivo biomarkers"> in vivo biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=memory" title=" memory"> memory</a>, <a href="https://publications.waset.org/abstracts/search?q=PET" title=" PET"> PET</a>, <a href="https://publications.waset.org/abstracts/search?q=tau" title=" tau"> tau</a> </p> <a href="https://publications.waset.org/abstracts/157419/medial-temporal-tau-predicts-memory-decline-in-cognitively-unimpaired-elderly" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157419.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">45</span> Urban Meetings: Graphic Analysis of the Public Space in a Cultural Building from São Paulo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thalita%20Carvalho%20Martins%20de%20Castro">Thalita Carvalho Martins de Castro</a>, <a href="https://publications.waset.org/abstracts/search?q=N%C3%BAbia%20Bernardi"> Núbia Bernardi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, studies evidence that our cities are portraits of social relations. In the midst of so many segregations, cultural buildings emerge as a place to assemble collective activities and expressions. Through theater, exhibitions, educational workshops, libraries, the architecture approaches human relations and seeks to propose meeting places. The purpose of this research is to deepen the discussions about the contributions of cultural buildings in the use of the spaces of the contemporary city, based on the data and measure collected in the master's research in progress. The graphic analysis of the insertion of contemporary cultural buildings seeks to highlight the social use of space. The urban insertions of contemporary cultural buildings in the city of São Paulo (Brazil) will be analyzed to understand the relations between the architectural form and its audience. The collected data describe a dynamic of flows and the permanence in the use of these spaces, indicating the contribution of the cultural buildings, associated with artistic production, in the dynamics of urban spaces and the social modifications of their milieu. Among the case studies, the research in development is based on the registration and graphic analysis of the Praça das Artes (2012) building located in the historical central region of the city, which after a long period of great degradation undergoes a current redevelopment. The choice of this building was based on four parameters, both on the architectural scale and on the urban scale: urban insertion, local impact, cultural production and a mix of uses. For the analysis will be applied two methodologies of graphic analysis, one with diagrams accompanied by texts and another with the active analysis for open space projects using complementary graphic methodologies, with maps, plants, info-graphics, perspectives, time-lapse videos and analytical tables. This research aims to reinforce the debates between the methodologies of form-use spaces and visual synthesis applied in cultural buildings, in order that new projects can structure public spaces as catalysts for social use, generating improvements in the daily life of its users and in the cities where they are inserted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20buildings" title="cultural buildings">cultural buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20methodologies" title=" design methodologies"> design methodologies</a>, <a href="https://publications.waset.org/abstracts/search?q=graphic%20analysis" title=" graphic analysis"> graphic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20spaces" title=" public spaces"> public spaces</a> </p> <a href="https://publications.waset.org/abstracts/69217/urban-meetings-graphic-analysis-of-the-public-space-in-a-cultural-building-from-sao-paulo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69217.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">306</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> Analysis of Genic Expression of Honey Bees Exposed to Sublethal Pesticides Doses Using the Transcriptome Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20de%20Oliveira%20Orsi">Ricardo de Oliveira Orsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aline%20Astolfi"> Aline Astolfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Diego%20Mendes"> Daniel Diego Mendes</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabella%20Cristina%20de%20Castro%20Lippi"> Isabella Cristina de Castro Lippi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaine%20da%20Luz%20Scheffer"> Jaine da Luz Scheffer</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Souza%20Lima"> Yan Souza Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Juliana%20Lunardi"> Juliana Lunardi</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanna%20do%20Padro%20Ribeiro"> Giovanna do Padro Ribeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Moura%20Kadri"> Samir Moura Kadri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> NECTAR Brazilian group (Center of Education, Science, and Technology in Rational Beekeeping) conducted studies on the pesticides honey bees effects using the transcriptome sequencing (RNA-Seq) analyzes for gene expression studies. In this way, we analyzed the effects of Pyraclostrobin and Fipronil on the honey bees with 21 old-days (forager) in laboratory conditions. For this, frames containing sealed brood were removed from the beehives and maintenance on the stove (32°C and 75% humidity) until the bees were born. So, newly emerged workers were marked on the pronotum with a non-toxic pen and reintroduced into their original hives. After 21 days, 120 marked bees were collected with an entomological forces and immediately stored in Petri dishes, perforated to ensure ventilation, and kept fasted for 3 hours. These honeybees were exposed to food contaminated or not with the sublethal dose of Pyraclostrobin (850 ppb/bee) or Fipronil (2.5 ppb/bee). After four hours of exposure, 15 bees from each treatment were referred to transcriptome analysis. Total RNA analysis was extracted from the brain pools (03 brains per pool) using the TRIzol® reagent protocol according to the manufacturer's instructions. cDNA libraries were constructed, and the FASTQC program was used to check adapter content and assess the quality of raw reads. Differential expression analysis was performed with the DESeq2 package. Genes that had an adjusted value of less than 0.05 were considered to be significantly up-regulated. Regarding the Pyraclostrobin, alterations were observed in the pattern of 17 gene related to of antioxidant system, cellular respiration, glucose metabolism, and regulation of juvenile hormone and the hormone insulin. Glyphosate altered the 10 gene related to the digestive system, exoskeleton composition, vitamin E transport, and antioxidant system. The results indicate that the necessity of studies using the sublethal doses to evaluate the pesticides uses and risks on crops and its effects on the honey bees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beekeeping" title="beekeeping">beekeeping</a>, <a href="https://publications.waset.org/abstracts/search?q=honey%20bees" title=" honey bees"> honey bees</a>, <a href="https://publications.waset.org/abstracts/search?q=pesticides" title=" pesticides"> pesticides</a>, <a href="https://publications.waset.org/abstracts/search?q=transcriptome" title=" transcriptome"> transcriptome</a> </p> <a href="https://publications.waset.org/abstracts/146544/analysis-of-genic-expression-of-honey-bees-exposed-to-sublethal-pesticides-doses-using-the-transcriptome-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146544.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">125</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">43</span> Counting Fishes in Aquaculture Ponds: Application of Imaging Sonars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20C.%20Gutierrez-Estrada">Juan C.

These fish rearing systems are approximately two thirds of aquatic production in this area which has made a significant contribution to the regional economy in recent years. In this type of rearing system, a crucial aspect is the correct quantification and control of the fish abundance in the ponds because the fish farmer knows how many fishes he puts in the ponds but doesn’t know how many fishes will harvest at the end of the rear period. This is a consequence of the mortality induced by different causes as pathogen agents as parasites, viruses and bacteria and other factors as predation of fish-eating birds and poaching. Track the fish abundance in these installations is very difficult because usually the ponds take up a large area of land and the management of the water flow is not automatized. Therefore, there is a very high degree of uncertainty on the abundance fishes which strongly hinders the management and planning of the sales. A novel and non-invasive procedure to count fishes in the ponds is by the means of imaging sonars, particularly fixed systems and/or linked to aquatic vehicles as Remotely Operated Vehicles (ROVs). In this work, a method based on census stations procedures is proposed to evaluate the fish abundance estimation accuracy using images obtained of multibeam sonars. The results indicate that it is possible to obtain a realistic approach about the number of fishes, sizes and therefore the biomass contained in the ponds.

Biofertilization is a cost-effective and sustainable alternative; improving strategies depends on isolating beneficial soil microorganisms. Although culturing is widespread in biofertilization, it is unknown whether the composition of cultured isolates closely mirrors native beneficial rhizobacterial populations. This study aimed to determine the relative abundance of culturable plant growth-promoting rhizobacteria (PGPR) isolates within total soil DNA and how potential PGPR populations respond to chemical fertilization in a commercial wheat variety. It was hypothesized that PGPR will be reduced in fertilized relative to unfertilized wheat. Triticum aestivum cv. Cadenza seeds were sown in a nutrient depleted agricultural soil in pots treated with and without nitrogen-phosphorous-potassium (NPK) fertilizer. Rhizosphere and rhizoplane samples were collected at flowering stage (10 weeks) and analyzed by culture-independent (amplicon sequence variance (ASV) analysis of total rhizobacterial DNA) and -dependent (isolation using growth media) techniques. Rhizosphere- and rhizoplane-derived microbiota culture collections were tested for plant growth-promoting traits using functional bioassays. In general, fertilizer addition decreased the proportion of nutrient-solubilizing bacteria (nitrate, phosphate, potassium, iron and, zinc) isolated from rhizocompartments in wheat, whereas salt tolerant bacteria were not affected. A PGPR database was created from isolate 16S rRNA gene sequences and searched against total soil DNA, revealing that 1.52% of total community ASVs were identified as culturable PGPR isolates. Bioassays identified a higher proportion of PGPR in non-fertilized samples (rhizosphere (49%) and rhizoplane (91%)) compared to fertilized samples (rhizosphere (21%) and rhizoplane (19%)) which constituted approximately 1.95% and 1.25% in non-fertilized and fertilized total community DNA, respectively. The analyses of 16S rRNA genes and deduced functional profiles provide an in-depth understanding of the responses of bacterial communities to fertilizer; this study suggests that rhizobacteria, which potentially benefit plants by mobilizing insoluble nutrients in soil, are reduced by chemical fertilizer addition. This knowledge will benefit the development of more targeted biofertilization strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteria" title="bacteria">bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=fertilizer" title=" fertilizer"> fertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiome" title=" microbiome"> microbiome</a>, <a href="https://publications.waset.org/abstracts/search?q=rhizoplane" title=" rhizoplane"> rhizoplane</a>, <a href="https://publications.waset.org/abstracts/search?q=rhizosphere" title=" rhizosphere"> rhizosphere</a> </p> <a href="https://publications.waset.org/abstracts/132075/effect-of-chemical-fertilizer-on-plant-growth-promoting-rhizobacteria-in-wheat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132075.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">307</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">41</span> Comparison of Two Methods of Cryopreservation of Testicular Tissue from Prepubertal Lambs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rensson%20Homero%20Celiz%20Ygnacio">Rensson Homero Celiz Ygnacio</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Aur%C3%A9lio%20Schiavo%20Novaes"> Marco Aurélio Schiavo Novaes</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucy%20Vanessa%20Sulca%20%C3%91aupas"> Lucy Vanessa Sulca Ñaupas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Paula%20Ribeiro%20Rodrigues"> Ana Paula Ribeiro Rodrigues</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cryopreservation of testicular tissue emerges as an alternative for the preservation of the reproductive potential of individuals who still cannot produce sperm; however, they will undergo treatments that may affect their fertility (e.g., chemotherapy). Therefore, the present work aims to compare two cryopreservation methods (slow freezing and vitrification) in testicular tissue of prepubertal lambs. For that, to obtain the testicular tissue, the animals were castrated and the testicles were collected immediately in a physiological solution supplemented with antibiotics. In the laboratory, the testis was split into small pieces. The total size of the testicular fragments was 3×3x1 mm³ and was placed in a dish contained in Minimum Essential Medium (MEM-HEPES). The fragments were distributed randomly into non-cryopreserved (fresh control), slow freezing (SF), and vitrified. To SF procedures, two fragments from a given male were then placed in a 2,0 mL cryogenic vial containing 1,0 mL MEM-HEPES supplemented with 20% fetal bovine serum (FBS) and 20% dimethylsulfoxide (DMSO). Tubes were placed into a Mr. Frosty™ Freezing container with isopropyl alcohol and transferred to a -80°C freezer for overnight storage. On the next day, each tube was plunged into liquid nitrogen (NL). For vitrification, the ovarian tissue cryosystem (OTC) device was used. Testicular fragments were placed in the OTC device and exposed to the first vitrification solution composed of MEM-HEPES supplemented with 10 mg/mL Bovine Serum Albumin (BSA), 0.25 M sucrose, 10% Ethylene glycol (EG), 10% DMSO and 150 μM alpha-lipoic acid for four min. The VS1 was discarded and then the fragments were submerged into a second vitrification solution (VS2) containing the same composition of VS1 but 20% EG and 20% DMSO. VS2 was then discarded and each OTC device containing up to four testicular fragments was closed and immersed in NL. After the storage period, the fragments were removed from the NL, kept at room temperature for one min and then immersed at 37 °C in a water bath for 30 s. Samples were warmed by sequentially immersing in solutions of MEM-HEPES supplemented with 3 mg/mL BSA and decreasing concentrations of sucrose. Hematoxylin-eosin staining to analyze the tissue architecture was used. The score scale used was from 0 to 3, classified with a score 0 representing normal morphologically, and 3 were considered a lot of alteration. The histomorphological evaluation of the testicular tissue shows that when evaluating the nuclear alteration (distinction of nucleoli and condensation of nuclei), there are no differences when using slow freezing with respect to the control. However, vitrification presents greater damage (p <0.05). On the other hand, when evaluating the epithelial alteration, we observed that the freezing showed scores statistically equal to the control in variables such as retraction of the basement membrane, formation of gaps and organization of the peritubular cells. The results of the study demonstrated that cryopreservation using the slow freezing method is an excellent tool for the preservation of pubertal testicular tissue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryopreservation" title="cryopreservation">cryopreservation</a>, <a href="https://publications.waset.org/abstracts/search?q=slow%20freezing" title=" slow freezing"> slow freezing</a>, <a href="https://publications.waset.org/abstracts/search?q=vitrification" title=" vitrification"> vitrification</a>, <a href="https://publications.waset.org/abstracts/search?q=testicular%20tissue" title=" testicular tissue"> testicular tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=lambs" title=" lambs"> lambs</a> </p> <a href="https://publications.waset.org/abstracts/142928/comparison-of-two-methods-of-cryopreservation-of-testicular-tissue-from-prepubertal-lambs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142928.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">174</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">40</span> The Physiological Effects of Thyriod Disorders During the Gestatory Period on Fetal Neurological Development: A Descriptive Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vanessa%20Bennemann">Vanessa Bennemann</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriela%20Laste"> Gabriela Laste</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1rcia%20In%C3%AAs%20Goettert"> Márcia Inês Goettert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The gestational period is a phase in which the pregnant woman undergoes constant physiological and hormonal changes, which are part of the woman’s biological cycle, the development of the fetus, childbirth, and lactation. These are factors of response to the immunological adaptation of the human reproductive process that is directly related to the pregnancy’s well-being and development. Although most pregnancies occur without complications, about 15% of pregnant women will develop potentially fatal complications, implying maternal and fetal risk. Therefore, requiring specialized care for high-risk pregnant women (HRPW) with obstetric interventions for the survival of the mother and/or fetus. Among the risk factors that characterize HRPW are the women's age, gestational diabetes mellitus (GDM), autoimmune diseases, infectious diseases such as syphilis and HIV, hypertension (SAH), preeclampsia, eclampsia, HELLP syndrome, uterine contraction abnormalities, and premature placental detachment (PPD), thyroid disorders, among others. Thus, pregnancy has an impact on the thyroid gland causing changes in the functioning of the mother's thyroid gland, altering the thyroid hormone (TH) profiles and production as pregnancy progresses. Considering, throughout the gestational period, the interpretation of the results of the tests to evaluate the thyroid functioning depends on the stage in which the pregnancy is. Thyroid disorders are directly related to adverse obstetric outcomes and in child development. Therefore, the adequate release of TH is important for a pregnancy without complications and optimal fetal growth and development. Objective: Investigate the physiological effects caused by thyroid disorders in the gestational period. Methods: A search for articles indexed in PubMed, Scielo, and MDPI databases, was performed using the term “AND”, with the descriptors: Pregnancy, Thyroid. With several combinations that included: Melatonin, Thyroidopathy, Inflammatory processes, Cytokines, Anti-inflammatory, Antioxidant, High-risk pregnancy. Subsequently, the screening was performed through the analysis of titles and/or abstracts. The criteria were: including clinical studies in general, randomized or not, in the period of 10 years prior to the research, in the English literature; excluded: experimental studies, case reports, research in the development phase. Results: In the preliminary results, a total of studies (n=183) were found, (n=57) excluded, such as studies of cancer, diabetes, obesity, and skin diseases. Conclusion: To date, it has been identified that thyroid diseases can impair the fetus’s brain development. Further research is suggested on this matter to identify new substances that may have a potential therapeutic effect to aid the gestational period with thyroid diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title="pregnancy">pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid" title=" thyroid"> thyroid</a>, <a href="https://publications.waset.org/abstracts/search?q=melatonin" title=" melatonin"> melatonin</a>, <a href="https://publications.waset.org/abstracts/search?q=high-risk%20pregnancy" title=" high-risk pregnancy"> high-risk pregnancy</a> </p> <a href="https://publications.waset.org/abstracts/148713/the-physiological-effects-of-thyriod-disorders-during-the-gestatory-period-on-fetal-neurological-development-a-descriptive-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148713.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">144</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">39</span> Biodegradation of Carbamazepine and Diclofenac by Bacterial Strain Labrys Portucalensis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20S.%20Bessa">V.

Pharmaceuticals are not completely mineralized in the human body and are released on the sewage systems as the pharmaceutical itself and as their “biologically active” metabolites through excretion, as well as by improper elimination and disposal. Conventional wastewater treatment plants (WWTPs) are not designed to remove these emerging pollutants and they are thus released into the environment. The antiepileptic drug carbamazepine (CBZ) and the non-steroidal anti-inflammatory diclofenac (DCF) are two widely used pharmaceuticals, frequently detected in water bodies, including rivers and groundwater, in concentrations ranging from ng L 1 to mg L 1. These two compounds were classified as medium to high-risk pollutants in WWTP effluents and surface waters. Also, CBZ has been suggested as a molecular marker of wastewater contamination in surface water and groundwater and the European Union included DCF in the watch list of substances Directive to be monitored. In the present study, biodegradation of CBZ and DCF by the bacterial strain Labrys portucalensis F11, a strain able to degrade other pharmaceutical compounds, was assessed; tests were performed with F11 as single carbon and energy source, as well as in presence of 5.9mM of sodium acetate. In assays supplemented with 2.0 and 4.0 µM of CBZ, the compound was no longer detected in the bulk medium after 24hr and 5days, respectively. Complete degradation was achieved in 21 days for 11.0 µM and in 23 days for 21.0 µM. For the highest concentration tested (43.0 µM), 95% of degradation was achieved in 30days. Supplementation with acetate increased the degradation rate of CBZ, for all tested concentrations. In the case of DCF, when supplemented as a single carbon source, approximately 70% of DCF (1.7, 3.3, 8.4, 17.5 and 34.0 µM) was degraded in 30days. Complete degradation was achieved in the presence of acetate for all tested concentrations, at higher degradation rates. The detection of intermediates produced during DCF biodegradation was performed by UPLC-QTOF/MS/MS, which allowed the identification of a range of metabolites. Stoichiometric liberation of chorine occurred and no metabolites were detected at the end of the biodegradation assays suggesting a complete mineralization of DCF. Strain Labrys portucalensis F11 proved to be able to degrade these two top priority environmental contaminants and may be potentially useful for biotechnological applications/environment remediation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradation" title="biodegradation">biodegradation</a>, <a href="https://publications.waset.org/abstracts/search?q=carbamazepine" title=" carbamazepine"> carbamazepine</a>, <a href="https://publications.waset.org/abstracts/search?q=diclofenac" title=" diclofenac"> diclofenac</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceuticals" title=" pharmaceuticals"> pharmaceuticals</a> </p> <a href="https://publications.waset.org/abstracts/61060/biodegradation-of-carbamazepine-and-diclofenac-by-bacterial-strain-labrys-portucalensis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61060.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">38</span> Anabasine Intoxication and its Relation to Plant Development Stages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tha%C3%ADs%20T.%20Val%C3%A9rio%20Caetano">Thaís T.

Stein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nicotiana glauca, commonly known as wild tobacco or tobacco bush, belongs to the Solanaceae family. It is native to South America but has become naturalized in various regions, including Australia, California, Africa, and the Mediterranean. N. glauca is listed in the Global Invasive Species Database (GISD) and the Invasive Species Compendium (CABI). It is known for producing pyridine alkaloids, including anabasine, which is highly toxic. Anabasine is predominantly found in the leaves and can cause severe health issues such as neuromuscular blockade, respiratory arrest, and cardiovascular problems when ingested. Mistaken identity with edible plants like spinach has resulted in food poisoning cases in Israel and Brazil. Anabasine, a minor alkaloid constituent of tobacco, may contribute to tobacco addiction by mimicking or enhancing the effects of nicotine. Therefore, it is essential to investigate the production pattern of anabasine and its relationship to the developmental stages of the plant. This study aimed to establish the relationship between the phenological plant age, cultivation place, and the increase in anabasine concentration, which can lead to human intoxication cases. In this study, N. glauca plants were collected from three different rural areas in Brazil for a year to examine leaves at various stages of development. Samples were also obtained from cultivated plants in Marilândia, Minas Gerais, Brazil, as well as from Divinópolis, Minas Gerais, Brazil, and Arraial do Cabo, Rio de Janeiro, Brazil. In vitro cultivated plants on MS medium were included in the study. The collected leaves were dried, powdered, and stored. Alkaloid extraction was performed using a methanol and water mixture, followed by liquid-liquid extraction with chloroform. The anabasine content was determined using HPLC-DAD analysis with nicotine as a standard. The results indicated that anabasine production increases with the plant's development, peaking in adult leaves during the reproduction phase and declining afterward. In vitro, plants showed similar anabasine production to young leaves. The successful adaptation of N. glauca in new environments poses a global problem, and the correlation between anabasine production and the plant's developmental stages has been understudied. The presence of substances produced by the plant can pose a risk to other species, especially when mistaken for edible plants. The findings from this study shed light on the pattern of anabasine production and its association with plant development, contributing to a better understanding of the potential risks associated with N. glauca and the importance of accurate identification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nicotiana%20glauca%20graham"
