oncologic patients with cholelithiasis and cholangitis process. Case description: A 59-years old Caucasian male diagnosed with extrahepatic cholangiocarcinoma with multiple liver, lung and peritoneum metastasis, unresponsive to treatment with gemcitabine/cisplatin, presented in the institution with fever, hypotension, and severe upper right abdominal pain secondary to cholelithiasis and cholangitis process. The patient was admitted and started on large spectrum antibiotics plus fluid-challenge. Afterward, a percutaneous transhepatic biliary drainage (PTBD) was performed to drain the gallbladder. This procedure temporarily stabilized the patient. However, the definitive solution required gallbladder removal. Since the patient exhibited an advanced oncologic disease and poor response to the chemotherapy, he was not a candidate for surgical intervention. Diagnostic Pathways: A self-expanding metal stent was placed from the duodenum into the bile duct by endoscopic ultrasound-guided. The stent allowed efficient drainage of the contrast from the gallbladder at the end of the endoscopic procedure. Conclusion and Discussion: The stent allowed efficient drainage of the contrast from the gallbladder at the end of the endoscopic procedure and successfully reversed the cholangitis process. EUS-CD is an effective and safe technique and can be used as a palliative care procedure for non-surgical oncologic patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palliative%20care" title="palliative care">palliative care</a>, <a href="https://publications.waset.org/abstracts/search?q=cholangiocarcinoma" title=" cholangiocarcinoma"> cholangiocarcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=choledochoduodenostomy" title=" choledochoduodenostomy"> choledochoduodenostomy</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20ultrasound-guided" title=" endoscopic ultrasound-guided"> endoscopic ultrasound-guided</a> </p> <a href="https://publications.waset.org/abstracts/140682/endoscopic-ultrasound-guided-choledochoduodenostomy-in-an-advanced-extrahepatic-cholangiocarcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140682.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">185</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> Nontraditional Online Student Perceptions of Student Success Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carrie%20Prendergast">Carrie Prendergast</a>, <a href="https://publications.waset.org/abstracts/search?q=Lisa%20Bortman"> Lisa Bortman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The focus of this presentation will be on non-traditional (adult) students as they seek their Bachelors’ degrees online. This presentation will specifically examine nontraditional online student perceptions of Tinto’s success conditions: expectations, support, assessment, and engagement. Expectations include those of the student, the faculty and the institution. Support includes academic, social, and financial support. Feedback and assessment encompasses feedback in the classroom, upon entry, and on an institutional level. The fourth success condition is involvement or engagement of students with their peers and faculty in both academic and social contexts. This program will review and discuss a rich, detailed description of the lived experience of the nontraditional online student to add to the paucity of research on this understudied population and guide higher education professionals in supporting this growing population of students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adult%20students" title="adult students">adult students</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20education" title=" online education"> online education</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20success" title=" student success"> student success</a>, <a href="https://publications.waset.org/abstracts/search?q=vincent%20tinto" title=" vincent tinto"> vincent tinto</a> </p> <a href="https://publications.waset.org/abstracts/52842/nontraditional-online-student-perceptions-of-student-success-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52842.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">373</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> The Collaboration between Resident and Non-resident Patent Applicants as a Strategy to Accelerate Technological Advance in Developing Nations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Rodr%C3%ADguez">Hugo Rodríguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Migrations of researchers, scientists, and inventors are a widespread phenomenon in modern times. In some cases, migrants stay linked to research groups in their countries of origin, either out of their own conviction or because of government policies. We examine different linear models of technological development (using the Ordinary Least Squares (OLS) technique) in eight selected countries and find that the collaborations between resident and nonresident patent applicants correlate with different levels of performance of the technological policies in three different scenarios. Therefore, the reinforcement of that link must be considered a powerful tool for technological development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=development" title="development">development</a>, <a href="https://publications.waset.org/abstracts/search?q=collaboration" title=" collaboration"> collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=patents" title=" patents"> patents</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/146728/the-collaboration-between-resident-and-non-resident-patent-applicants-as-a-strategy-to-accelerate-technological-advance-in-developing-nations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146728.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">127</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> Spectral Analysis Applied to Variables of Oil Wells Profiling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suzana%20Leit%C3%A3o%20Russo">Suzana Leitão Russo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayara%20Laysa%20de%20Oliveira%20Silva"> Mayara Laysa de Oliveira Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Augusto%20Andrade%20Filho"> José Augusto Andrade Filho</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitor%20Hugo%20Simon"> Vitor Hugo Simon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, seismic methods and prospecting methods are commonly applied in the oil industry and, according to the information reported every day; oil is a source of non-renewable energy.

There is a growing recognition of the need for alternative risk measures that do not make these assumptions. We propose a novel method for modeling the risk associated with investment products, in particular derivatives, by using a formal language for specifying financial contracts. Expressions in this language are interpreted in the category of values annotated with (a formal representation of) uncertainty. The choice of uncertainty formalism thus becomes a parameter of the model, so it can be adapted to the particular application and it is not constrained to classical probabilities. We demonstrate our approach using a simple logic-based uncertainty model and a case study in which we assess the risk of counter party default in a portfolio of collateralized loans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20model" title="risk model">risk model</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty%20monad" title=" uncertainty monad"> uncertainty monad</a>, <a href="https://publications.waset.org/abstracts/search?q=derivatives" title=" derivatives"> derivatives</a>, <a href="https://publications.waset.org/abstracts/search?q=contract%20algebra" title=" contract algebra"> contract algebra</a> </p> <a href="https://publications.waset.org/abstracts/28143/uncertainty-in-risk-modeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28143.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">576</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> A General Strategy for Noise Assessment in Open Mining Industries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20Mauricio%20Murillo%20Gomez">Diego Mauricio Murillo Gomez</a>, <a href="https://publications.waset.org/abstracts/search?q=Enney%20Leon%20Gonzalez%20%20Ramirez"> Enney Leon Gonzalez Ramirez</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Piedrahita"> Hugo Piedrahita</a>, <a href="https://publications.waset.org/abstracts/search?q=Jairo%20Yate"> Jairo Yate</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a methodology for the management of noise in open mining industries based on an integral concept, which takes into consideration occupational and environmental noise as a whole. The approach relies on the characterization of sources, the combination of several measurements’ techniques and the use of acoustic prediction software. A discussion about the difference between frequently used acoustic indicators such as Leq and LAV is carried out, aiming to establish common ground for homologation. The results show that the correct integration of this data not only allows for a more robust technical analysis but also for a more strategic route of intervention as several departments of the company are working together. Noise control measurements can be designed to provide a healthy acoustic surrounding in which the exposure workers but also the outdoor community is benefited. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20noise" title="environmental noise">environmental noise</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20control" title=" noise control"> noise control</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20noise" title=" occupational noise"> occupational noise</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20mining" title=" open mining"> open mining</a> </p> <a href="https://publications.waset.org/abstracts/136802/a-general-strategy-for-noise-assessment-in-open-mining-industries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136802.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">268</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> A Different Perspective on the Sustainability of Logistics Service Providers in City Logistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugo%20de%20Tarragon">Hugo de Tarragon</a>, <a href="https://publications.waset.org/abstracts/search?q=Martine%20Hlady-Rispal"> Martine Hlady-Rispal</a>, <a href="https://publications.waset.org/abstracts/search?q=Gauthier%20Casteran"> Gauthier Casteran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rooted in ethnographic research on city logistics, our paper examines how Logistics Service Providers (LSP) can move from a "subservient" posture to one of instigating the sustainable transformation of city logistics, using literature on sustainable city logistics. To do so, we start by providing a representation of the subservient posture adopted by LSPs during their interactions with stakeholders. We then mobilize ecosystem theories to analyze the follower posture LSP can adopt to ensure their financial, human, and environmental sustainability in a city logistics ecosystem. This study contributes to local authorities’ greater consideration/involvement of LSP in the definition of their city logistics strategy. It can also provide LSP with an insight into the transformations to be carried out to improve their sustainability.

Although they bring several benefits, their malfunctions can lead to severe consequences, such as personal injury of road users. Functional safety is an approach to identify these critical malfunctions and arrange technical systems that include only tolerable risk. This approach is– in comparison with other technical areas– relatively new in the automotive sector. For a long time, the automotive systems have based on mechanical components and approved principles, like robust design. With a growing number of electric and electronic components in the modern cars and realizing by software of the system functions, the need for new standards and methods to assure the functional safety has arisen.

With a growing demand for minerals and an increasing cost associated with extraction, companies are constantly re-evaluating the viability of mineral deposits and challenging their geological understanding. Within Rio Tinto Iron Ore, the Structural Geology (SG) team investigate and collect critical data, such as point based orientations, mapping and geological inferences from adjacent pits to re-model deposits where previous interpretations have failed to account for structurally controlled slope failures. Utilizing innovative data collection methods and data-driven investigation, SG aims to address the root causes of slope instability. Committing to a resource grid drill campaign as the primary source of data collection will often bias data collection to a specific orientation and significantly reduce the capability to identify and qualify complexity. Consequently, these limitations make it difficult to construct a realistic and coherent structural model that identifies adverse structural domains. Without the consideration of complexity and the capability of capturing these structural domains, mining operations run the risk of inadequately designed slopes that may fail and potentially harm people. Regional structural trends have been considered in conjunction with surface and in-pit mapping data to model multi-batter fold structures that were absent from previous iterations of the structural model. The risk is evident in newly identified dip-slope and rock-mass controlled sectors of the geotechnical design rather than a ubiquitous dip-slope sector across the pit. The reward is two-fold: 1) providing sectors of rock-mass controlled design in previously interpreted structurally controlled domains and 2) the opportunity to optimize the slope angle for mineral recovery and reduced strip ratio. Furthermore, a resulting high confidence model with structures and geometries that can account for historic slope instabilities in structurally controlled domains where design assumptions failed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structural%20geology" title="structural geology">structural geology</a>, <a href="https://publications.waset.org/abstracts/search?q=geotechnical%20design" title=" geotechnical design"> geotechnical design</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=slope%20stability" title=" slope stability"> slope stability</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20mitigation" title=" risk mitigation"> risk mitigation</a> </p> <a href="https://publications.waset.org/abstracts/186342/structural-analysis-and-modelling-in-an-evolving-iron-ore-operation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186342.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">46</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> The Importance of Patenting and Technology Exports as Indicators of Economic Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Rodr%C3%ADguez">Hugo Rodríguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The patenting of inventions is the result of an organized effort to achieve technological improvement and its consequent positive impact on the population's standard of living. Technology exports, either of high-tech goods or of Information and Communication Technology (ICT) services, represent the level of acceptance that world markets have of that technology acquired or developed by a country, either in public or private settings. A quantitative measure of the above variables is expected to have a positive and relevant impact on the level of economic development of the countries, measured on this first occasion through their level of Gross Domestic Product (GDP). And in that sense, it not only explains the performance of an economy but the difference between nations. We present an econometric model where we seek to explain the difference between the GDP levels of 178 countries through their different performance in the outputs of the technological production process. We take the variables of Patenting, ICT Exports and High Technology Exports as results of the innovation process. This model achieves an explanatory power for four annual cuts (2000, 2005, 2010 and 2015) equivalent to an adjusted r2 of 0.91, 0.87, 0.91 and 0.96, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Development" title="Development">Development</a>, <a href="https://publications.waset.org/abstracts/search?q=exports" title=" exports"> exports</a>, <a href="https://publications.waset.org/abstracts/search?q=patents" title=" patents"> patents</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/129123/the-importance-of-patenting-and-technology-exports-as-indicators-of-economic-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129123.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">110</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> Overcrowding and Adequate Housing: The Potential of Adaptability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=In%C3%AAs%20Ramalhete">Inês Ramalhete</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Farias"> Hugo Farias</a>, <a href="https://publications.waset.org/abstracts/search?q=Rui%20da%20Silva%20Pinto"> Rui da Silva Pinto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Adequate housing has been a widely discussed theme in academic circles related to low-cost housing, whereas its physical features are easy to deal with, overcrowding (related to social, cultural and economic aspects) is still ambiguous, particularly regarding the set of indicators that can accurately reflect and measure it. This paper develops research on low-cost housing models for developing countries and what is the best method to embed overcrowding as an important parameter for adaptability. A critical review of international overcrowding indicators and their application in two developing countries, Cape Verde and Angola, is presented. The several rationales and the constraints for an accurate assessment of overcrowding are considered, namely baseline data (statistics), which can induce misjudgments, as well as social and cultural factors (such as personal choices of residents). This paper proposes a way to tackle overcrowding through housing adaptability, considering factors such as physical flexibility, functional ambiguity, and incremental expansion schemes. Moreover, a case-study is presented to establish a framework for the theoretical application of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20housing" title="adaptive housing">adaptive housing</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20cost%20housing" title=" low cost housing"> low cost housing</a>, <a href="https://publications.waset.org/abstracts/search?q=overcrowding" title=" overcrowding"> overcrowding</a>, <a href="https://publications.waset.org/abstracts/search?q=housing%20model" title=" housing model"> housing model</a> </p> <a href="https://publications.waset.org/abstracts/86914/overcrowding-and-adequate-housing-the-potential-of-adaptability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86914.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">191</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> Quantifying Product Impacts on Biodiversity: The Product Biodiversity Footprint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leveque%20Benjamin">Leveque Benjamin</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabaud%20Suzanne"> Rabaud Suzanne</a>, <a href="https://publications.waset.org/abstracts/search?q=Anest%20Hugo"> Anest Hugo</a>, <a href="https://publications.waset.org/abstracts/search?q=Catalan%20Caroline"> Catalan Caroline</a>, <a href="https://publications.waset.org/abstracts/search?q=Neveux%20Guillaume"> Neveux Guillaume</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human products consumption is one of the main drivers of biodiversity loss. However, few pertinent ecological indicators regarding product life cycle impact on species and ecosystems have been built. Life cycle assessment (LCA) methodologies are well under way to conceive standardized methods to assess this impact, by taking already partially into account three of the Millennium Ecosystem Assessment pressures (land use, pollutions, climate change). Coupling LCA and ecological data and methods is an emerging challenge to develop a product biodiversity footprint. This approach was tested on three case studies from food processing, textile, and cosmetic industries. It allowed first to improve the environmental relevance of the Potential Disappeared Fraction of species, end-point indicator typically used in life cycle analysis methods, and second to introduce new indicators on overexploitation and invasive species. This type of footprint is a major step in helping companies to identify their impacts on biodiversity and to propose potential improvements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title="biodiversity">biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=companies" title=" companies"> companies</a>, <a href="https://publications.waset.org/abstracts/search?q=footprint" title=" footprint"> footprint</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=products" title=" products"> products</a> </p> <a href="https://publications.waset.org/abstracts/61583/quantifying-product-impacts-on-biodiversity-the-product-biodiversity-footprint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61583.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">327</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> Afghan Refugees as Perpetui Inimici: Revisiting an Early Modern Debate on Enemy Aliens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brian%20Smith">Brian Smith</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper seeks to contrast the contemporary anti-immigration rhetoric since the US pullout of Afghanistan with the debate about enemy aliens in the early modern period. In the seventeenth century, Sir Edward Coke declared that “infidels” should be seen as perpetui inimici (perpetual enemies) since their values were inimical to those of Christian states. As such, they could be perpetually excluded and denied legal standing. Even at that time, these anti-“infidel” arguments clashed with the natural law tradition of hospitality, which assumed that states had a moral responsibility to admit and care for strangers. In particular, this paper looks at the conflict between Hugo Grotius, Samuel Pufendorf, and John Locke. Grotius argues that states have a duty to admit foreigners. He goes out of his way to plan for the admittance of Jewish immigrants. In contrast, Pufendorf claimed that sovereigns had a duty exclude foreigners who would alter the constitutional character of the state. Much like Grotius, Locke argued that non-Christian peoples should be treated as friends and admitted without reservation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enemy%20aliens" title="enemy aliens">enemy aliens</a>, <a href="https://publications.waset.org/abstracts/search?q=perpetual%20enemies" title=" perpetual enemies"> perpetual enemies</a>, <a href="https://publications.waset.org/abstracts/search?q=hospitality" title=" hospitality"> hospitality</a>, <a href="https://publications.waset.org/abstracts/search?q=refugees" title=" refugees"> refugees</a> </p> <a href="https://publications.waset.org/abstracts/156104/afghan-refugees-as-perpetui-inimici-revisiting-an-early-modern-debate-on-enemy-aliens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156104.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">107</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> Wireless Sensor Networks for Water Quality Monitoring: Prototype Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Eduardo%20Hern%C3%A1ndez%20Curiel">Cesar Eduardo Hernández Curiel</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Hugo%20Ben%C3%ADtez%20Baltazar"> Victor Hugo Benítez Baltazar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20Horacio%20Pacheco%20Ram%C3%ADrez"> Jesús Horacio Pacheco Ramírez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is devoted to present the advances in the design of a prototype that is able to supervise the complex behavior of water quality parameters such as pH and temperature, via a real-time monitoring system. The current water quality tests that are performed in government water quality institutions in Mexico are carried out in problematic locations and they require taking manual samples. The water samples are then taken to the institution laboratory for examination. In order to automate this process, a water quality monitoring system based on wireless sensor networks is proposed. The system consists of a sensor node which contains one pH sensor, one temperature sensor, a microcontroller, and a ZigBee radio, and a base station composed by a ZigBee radio and a PC. The progress in this investigation shows the development of a water quality monitoring system. Due to recent events that affected water quality in Mexico, the main motivation of this study is to address water quality monitoring systems, so in the near future, a more robust, affordable, and reliable system can be deployed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pH%20measurement" title="pH measurement">pH measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality%20monitoring" title=" water quality monitoring"> water quality monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title=" wireless sensor networks"> wireless sensor networks</a>, <a href="https://publications.waset.org/abstracts/search?q=ZigBee" title=" ZigBee"> ZigBee</a> </p> <a href="https://publications.waset.org/abstracts/43281/wireless-sensor-networks-for-water-quality-monitoring-prototype-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43281.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">404</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> Experimental Study of the Infill Masonry Walls Response Subjected to Out-Of-Plane Static Loadings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9%20Furtado">André Furtado</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Rodrigues"> Hugo Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Ant%C3%B3nio%20Ar%C3%AAde"> António Arêde</a>, <a href="https://publications.waset.org/abstracts/search?q=Humberto%20Varum"> Humberto Varum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Besides characterized as non-structural elements, infill masonry (IM) walls have an important contribute in the structural response of reinforced concrete structures as proved by the damages observed recent earthquakes.

The aim of this research is to contribute to the increase of understanding regarding the OOP behaviour of full-scale infill panels considering different variables such as panel support width and axial load on the top of columns. For this, it was carried out in the Laboratory of Earthquake and Structural Engineering (LESE) an experimental campaign of five full-scale IM walls subjected to OOP distributed cyclic loadings. Specimens with different variables such as previous in-plane damage, support conditions, axial load on the top of the columns were studied. The results will be presented and discussed along the manuscript in terms of force-displacement hysteretic curves, cracking pattern, initial stiffness, stiffness degradation and accumulative energy dissipation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infill%20masonry%20walls" title="infill masonry walls">infill masonry walls</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20testing" title=" experimental testing"> experimental testing</a>, <a href="https://publications.waset.org/abstracts/search?q=out-of-plane" title=" out-of-plane"> out-of-plane</a>, <a href="https://publications.waset.org/abstracts/search?q=full-scale" title=" full-scale"> full-scale</a> </p> <a href="https://publications.waset.org/abstracts/64433/experimental-study-of-the-infill-masonry-walls-response-subjected-to-out-of-plane-static-loadings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64433.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">390</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> Experimental Characterization and Modelling of Microfluidic Radial Diffusers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20Chappel">Eric Chappel</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitry%20Dumont-Fillon"> Dimitry Dumont-Fillon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Musard"> Hugo Musard</a>, <a href="https://publications.waset.org/abstracts/search?q=Harald%20van%20Lintel"> Harald van Lintel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A microfluidic radial diffuser typically comprises a hole in a membrane, a small gap and pillar centred with the hole.

The fluidic modelling of such diffuser is made difficult by the presence of a transition region between the hole and the diffuser itself. An experimental investigation has been conducted using SOI wafers to form membranes with only one centred hole and Pyrex wafers for the substrate and pillars, both wafers being anodically bonded after alignment. A simple fluidic model accounting for the specific geometry of the diffuser is proposed and compared to experimental results. A good match is obtained, for Reynolds number in the range 0.5 to 35 using the analytical formula of a radial diffuser in the laminar regime with an effective inner radius that is 40% smaller than the real radius, in order to simulate correctly the flow constriction at the entrance of the diffuser. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radial%20diffuser" title="radial diffuser">radial diffuser</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20control%20valve" title=" flow control valve"> flow control valve</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modelling" title=" numerical modelling"> numerical modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a> </p> <a href="https://publications.waset.org/abstracts/84032/experimental-characterization-and-modelling-of-microfluidic-radial-diffusers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84032.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">278</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> Racial Microaggressions: Experiences among International Students in Australia and Its Impact on Stress and Psychological Wellbeing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugo%20M.%20Gonzales">Hugo M.

This study investigated the prevalence of racial microaggressions among international students and their impact on stress and psychological well-being. This research was conducted during the COVID-19 pandemic, which has been documented to contribute to anti-Asian racism. Participants included 54 international students, of which 72% were Asian. The Racial and Ethnic Microaggressions Scale (REMS), Perceived Stress Scale (PSS), and the Perceived General Wellbeing Indicator (PGWBI) were used to measure the participants’ responses. All participants reported experiencing racial microaggression in the last six months, and significant correlations and regression models were found between REMS, certain elements of the PSS scale, and time in Australia. Despite the small sample size, this research corroborated outcomes from recent studies and provided insight into the prevalence and impact of racial microaggressions among such populations, highlighting the need for further exploration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=racial%20microaggressions" title="racial microaggressions">racial microaggressions</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20students" title=" international students"> international students</a>, <a href="https://publications.waset.org/abstracts/search?q=racism" title=" racism"> racism</a>, <a href="https://publications.waset.org/abstracts/search?q=REMS" title=" REMS"> REMS</a>, <a href="https://publications.waset.org/abstracts/search?q=microaggressions%20in%20Australia" title=" microaggressions in Australia"> microaggressions in Australia</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20wellbeing" title=" psychological wellbeing"> psychological wellbeing</a> </p> <a href="https://publications.waset.org/abstracts/160533/racial-microaggressions-experiences-among-international-students-in-australia-and-its-impact-on-stress-and-psychological-wellbeing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160533.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">129</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> The Shrinking of the Pink Wave and the Rise of the Right-Wing in Latin America</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20M.%20Moda">B.

Secco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Through free and fair elections and others less democratic processes, Latin America has been gradually turning into a right-wing political region. In order to understand these recent changes, this paper aims to discuss the origin and the traits of the pink wave in the subcontinent, the reasons for its current rollback and future projections for left-wing in the region. The methodology used in this paper will be descriptive and analytical combined with secondary sources mainly from the social and political sciences fields. The canons of the Washington Consensus was implemented by the majority of the Latin American governments in the 80s and 90s under the social democratic and right-wing parties. The neoliberal agenda caused political, social and economic dissatisfaction bursting into a new political configuration for the region. It started in 1998 when Hugo Chávez took the office in Venezuela through the Fifth Republic Movement under the socialist flag. From there on, Latin America was swiped by the so-called ‘pink wave’, term adopted to define the rising of self-designated left-wing or center-left parties with a progressive agenda. After Venezuela, countries like Chile, Brazil, Argentina, Uruguay, Bolivia, Equator, Nicaragua, Paraguay, El Salvador and Peru got into the pink wave. The success of these governments was due a post-neoliberal agenda focused on cash transfers programs, increasing of public spending, and the straightening of national market. The discontinuation of the preference for the left-wing started in 2012 with the coup against Fernando Lugo in Paraguay. In 2015, the chavismo in Venezuela lost the majority of the legislative seats. In 2016, an impeachment removed the Brazilian president Dilma Rousself from office who was replaced by the center-right vice-president Michel Temer. In the same year, Mauricio Macri representing the right-wing party Proposta Republicana was elected in Argentina. In 2016 center-right and liberal, Pedro Pablo Kuczynski was elected in Peru. In 2017, Sebastián Piñera was elected in Chile through the center-right party Renovación Nacional. The pink wave current rollback points towards some findings that can be arranged in two fields. Economically, the 2008 financial crisis affected the majority of the Latin American countries and the left-wing economic policies along with the end of the raw materials boom and the subsequent shrinking of economic performance opened a flank for popular dissatisfaction. In Venezuela, the 2014 oil crisis reduced the revenues for the State in more than 50% dropping social spending, creating an inflationary spiral, and consequently loss of popular support. Politically, the death of Hugo Chavez in 2013 weakened the ‘socialism of the twenty first century’ ideal, which was followed by the death of Fidel Castro, the last bastion of communism in the subcontinent. In addition, several cases of corruption revealed during the pink wave governments made the traditional politics unpopular. These issues challenge the left-wing to develop a future agenda based on innovation of its economic program, improve its legal and political compliance practices, and to regroup its electoral forces amid the social movements that supported its ascension back in the early 2000s. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latin%20America" title="Latin America">Latin America</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20parties" title=" political parties"> political parties</a>, <a href="https://publications.waset.org/abstracts/search?q=left-wing" title=" left-wing"> left-wing</a>, <a href="https://publications.waset.org/abstracts/search?q=right-wing" title=" right-wing"> right-wing</a>, <a href="https://publications.waset.org/abstracts/search?q=pink%20wave" title=" pink wave"> pink wave</a> </p> <a href="https://publications.waset.org/abstracts/92299/the-shrinking-of-the-pink-wave-and-the-rise-of-the-right-wing-in-latin-america" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92299.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">240</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> Effect of Nutrient Limitations in Phycocyanin Formation by Spirulina platensis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugo%20F.%20Lobaton">Hugo F. Lobaton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cyanobacterium Spirulina platensis is a prokaryotic photoautotrophic microorganism that is successfully cultivated for the commercialization as whole biomass due to its high protein content and promising valuable substance. For instance, phycocyanin has recently drawn the interest of the food and cosmetic industries due to its bright blue colour and its strong antioxidant capacities. The phycocyanin (PC) is the main protein-pigment in S. platensis (4% to 20%). In batches, the rate of overproduction of metabolites by cyanobacteria is limited or activated by the depletion of required substrates. The aim of this study was to develop a kinetic law that describes phycocyanin formation during batch cultivation. S. platensis was cultivated in 1 L bubble column photobioreactor with 30°C and 700 µmol m⁻² s⁻¹. Culture samples were daily collected from the bubble columns in sterile conditions. The biomass (g l⁻¹) was measured directly after a biomass lyophilisation process, and phycocyanin extractions and measurements were done according to a well-established protocol. A kinetic law for phycocyanin formation that includes nitrate and bicarbonate limitations was proposed and linked to the biomass core model. The set of differential equations were solved in MATLAB. Concerning to product formation, the experimental results show that phycocyanin mass fraction is degraded as results of the complete nitrate depletion and nitrate additions during the cultivation help to keep constant this molecule until new macro-element limitation appear. According to the model, bicarbonate is this limitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phycocyanin" title="phycocyanin">phycocyanin</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrate" title=" nitrate"> nitrate</a>, <a href="https://publications.waset.org/abstracts/search?q=bicarbonate" title=" bicarbonate"> bicarbonate</a>, <a href="https://publications.waset.org/abstracts/search?q=spirulina" title=" spirulina"> spirulina</a> </p> <a href="https://publications.waset.org/abstracts/105879/effect-of-nutrient-limitations-in-phycocyanin-formation-by-spirulina-platensis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105879.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">146</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> Temporospatial Mediator: Site-Specific Theatre within Cultural Heritages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ching-Pin%20Tseng">Ching-Pin Tseng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cultural heritages are tangible and intangible catalysts for recollecting collective memories and cultural signification. Through visiting the heritage and with the aid of exhibition and visual indications, the visitor may visually and spatially grasp some fragments of the stories and occurrences of the site. However, there may be some discrepancies between the narration of historical happenings that occurred at the place and the spatial exhibition of the historic monument. Narratives of collective events may not be revealed merely by physical relics or objects. In order to build up a connection between the past and the present, the paper thus intends to discuss what means can engender vitalizations within cultural heritages. As the preservation of cultural heritages has been a universal consensus and common interests, its association with modern lives has also been an important issue. The paper will explore some site-specific theatres held in the art festivals in the south of Taiwan so as to examine the correlation between site-specific performances and the conservation of historic monuments. In the light of Victor Hugo’s argument that the place where events happened before can be silent characters for representing the reality of art and for impressing the spectator, this paper argues that site-specific theatres may bring vitality into tangible cultural heritages. At the end of this paper, the notion of localization will be utilized to examine the spatial setting and the materiality of scenic design in relation to the site-specific theatres within cultural heritages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=site-specificity" title="site-specificity">site-specificity</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20heritage" title=" cultural heritage"> cultural heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=localization" title=" localization"> localization</a>, <a href="https://publications.waset.org/abstracts/search?q=materiality" title=" materiality"> materiality</a> </p> <a href="https://publications.waset.org/abstracts/132576/temporospatial-mediator-site-specific-theatre-within-cultural-heritages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132576.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">124</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> Tomato-Weed Classification by RetinaNet One-Step Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dionisio%20Andujar">Dionisio Andujar</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20l%C3%B3pez-Correa"> Juan lópez-Correa</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Moreno"> Hugo Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Angela%20Ri"> Angela Ri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increased number of weeds in tomato crops highly lower yields. Weed identification with the aim of machine learning is important to carry out site-specific control. The last advances in computer vision are a powerful tool to face the problem. The analysis of RGB (Red, Green, Blue) images through Artificial Neural Networks had been rapidly developed in the past few years, providing new methods for weed classification. The development of the algorithms for crop and weed species classification looks for a real-time classification system using Object Detection algorithms based on Convolutional Neural Networks. The site study was located in commercial corn fields. The classification system has been tested. The procedure can detect and classify weed seedlings in tomato fields. The input to the Neural Network was a set of 10,000 RGB images with a natural infestation of Cyperus rotundus l., Echinochloa crus galli L., Setaria italica L., Portulaca oeracea L., and Solanum nigrum L. The validation process was done with a random selection of RGB images containing the aforementioned species. The mean average precision (mAP) was established as the metric for object detection. The results showed agreements higher than 95 %. The system will provide the input for an online spraying system. Thus, this work plays an important role in Site Specific Weed Management by reducing herbicide use in a single step. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title="deep learning">deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20detection" title=" object detection"> object detection</a>, <a href="https://publications.waset.org/abstracts/search?q=cnn" title=" cnn"> cnn</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato" title=" tomato"> tomato</a>, <a href="https://publications.waset.org/abstracts/search?q=weeds" title=" weeds"> weeds</a> </p> <a href="https://publications.waset.org/abstracts/158383/tomato-weed-classification-by-retinanet-one-step-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158383.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">103</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> Experimental Characterization of Anti-Icing System and Accretion of Re-Emitted Droplets on Turbojet Engine Blades</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guillaume%20Linassier">Guillaume Linassier</a>, <a href="https://publications.waset.org/abstracts/search?q=Morgan%20Balland"> Morgan Balland</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Pervier"> Hugo Pervier</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Pervier"> Marie Pervier</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Hammond"> David Hammond</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Atmospheric icing for turbojet is caused by ingestion of super-cooled water droplets. To prevent operability risks, manufacturer can implement ice protection systems. Thermal systems are commonly used for this purpose, but their activation can cause the formation of a water liquid film, that can freeze downstream the heated surface or even on other components. In the framework of STORM, a European project dedicated to icing physics in turbojet engines, a cascade rig representative of engine inlet blades was built and tested in an icing wind tunnel. This mock-up integrates two rows of blades, the upstream one being anti-iced using an electro-thermal device the downstream one being unheated. Under icing conditions, the anti-icing system is activated and set at power level to observe a liquid film on the surface and droplet re-emission at the trailing edge. These re-emitted droplets will impinge on the downstream row and contribute to ice accretion. A complete experimental database was generated, including the characterization of ice accretion shapes, and the characterization of electro-thermal anti-icing system (power limit for apparition of the runback water or ice accretion). These data will be used for validation of numerical tools for modeling thermal anti-icing systems in the scope of engine application, as well as validation of re-emission droplets model for stator parts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=turbomachine" title="turbomachine">turbomachine</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-icing" title=" anti-icing"> anti-icing</a>, <a href="https://publications.waset.org/abstracts/search?q=cascade%20rig" title=" cascade rig"> cascade rig</a>, <a href="https://publications.waset.org/abstracts/search?q=runback%20water" title=" runback water "> runback water </a> </p> <a href="https://publications.waset.org/abstracts/80186/experimental-characterization-of-anti-icing-system-and-accretion-of-re-emitted-droplets-on-turbojet-engine-blades" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80186.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">182</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">42</span> Development of Affordable and Reliable Diagnostic Tools to Record Vital Parameters for Improving Health Care in Low Resources Settings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mannan%20Mridha">Mannan Mridha</a>, <a href="https://publications.waset.org/abstracts/search?q=Usama%20Gazay"> Usama Gazay</a>, <a href="https://publications.waset.org/abstracts/search?q=Kosovare%20V.%20Aslani"> Kosovare V.

Health care workers and paramedics, called village doctors, informal healthcare providers, are largely responsible for the rural medical care. Mishaps due to wrong diagnosis and inappropriate medication have been causing serious suffering that is preventable. While innovators have created many devices, the vast majority of these technologies do not find applications to address the needs and conditions in low-resource settings. The primary motive is to address the acute lack of affordable medical technologies for the poor people in low-resource settings. A low cost smart medical device that is portable, battery operated and can be used at any point of care has been developed to detect breathing rate, electrocardiogram (ECG) and arterial pulse rate to improve diagnosis and monitoring of patients and thus improve care and safety<em>. </em>This simple and easy to use smart medical device can be used, managed and maintained effectively and safely by any health worker with some training.

The main question that remains unanswered is related to the influence of the source position on the sound power radiated by a complex wall-floor system in buildings. This research is concerned with the investigation of vibration transmission across walls and floors in buildings. It is primarily based on the determination of vibration reduction index via experimental tests. Knowledge of this parameter may help in predicting noise and vibration propagation in building components. First, the physical mechanisms involving vibration transmission across structural junctions are described. An experimental setup is performed to aid this investigation. The experimental tests have shown that the vibration generation in the walls and floors is directed related to their size and boundary conditions. It is also shown that the vibration source position can affect the overall vibration spectrum significantly. Second, the characteristics of the noise spectra inside the rooms due to an impact source (tapping machine) are also presented. Conclusions are drawn for the general trend of vibration and noise spectrum of the structural components and rooms, respectively. In summary, the aim of this paper is to investigate the vibro-acoustical behavior of building floors and walls under floor impact excitation. The impact excitation was at distinct positions on the slab. The analysis has highlighted the main physical characteristics of the vibration transmission mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vibration%20transmission" title="vibration transmission">vibration transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20reduction%20index" title=" vibration reduction index"> vibration reduction index</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20excitation" title=" impact excitation"> impact excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20tests" title=" experimental tests"> experimental tests</a> </p> <a href="https://publications.waset.org/abstracts/155098/vibration-transmission-across-junctions-of-walls-and-floors-in-an-apartment-building-an-experimental-investigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155098.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">93</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> Remittances and Water Access: A Cross-Sectional Study of Sub Saharan Africa Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narges%20Ebadi">Narges Ebadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Davod%20Ahmadi"> Davod Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiliary%20Monteith"> Hiliary Monteith</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Melgar-Quinonez"> Hugo Melgar-Quinonez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Migration cannot necessarily relieve pressure on water resources in origin communities, and male out-migration can increase the water management burden of women. However, inflows of financial remittances seem to offer possibilities of investing in improving drinking-water access. Therefore, remittances may be an important pathway for migrants to support water security. This paper explores the association between water access and the receipt of remittances in households in sub-Saharan Africa. Data from round 6 of the 'Afrobarometer' surveys in 2016 were used (n= 49,137). Descriptive, bivariate and multivariate statistical analyses were carried out in this study. Regardless of country, findings from descriptive analyses showed that approximately 80% of the respondents never received remittance, and 52% had enough clean water. Only one-fifth of the respondents had piped water supply inside the house (19.9%), and approximately 25% had access to a toilet inside the house. Bivariate analyses revealed that even though receiving remittances was significantly associated with water supply, the strength of association was very weak. However, other factors such as the area of residence (rural vs. urban), cash income frequencies, electricity access, and asset ownership were strongly associated with water access. Results from unadjusted multinomial logistic regression revealed that the probability of having no access to piped water increased among remittance recipients who received financial support at least once a month (OR=1.324) (p < 0.001). In contrast, those not receiving remittances were more likely to regularly have a water access concern (OR=1.294) (p < 0.001), and not have access to a latrine (OR=1.665) (p < 0.001). In conclusion, receiving remittances is significantly related to water access as the strength of odds ratios for socio-demographic factors was stronger. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=remittances" title="remittances">remittances</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20access" title=" water access"> water access</a>, <a href="https://publications.waset.org/abstracts/search?q=SSA" title=" SSA"> SSA</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a> </p> <a href="https://publications.waset.org/abstracts/107121/remittances-and-water-access-a-cross-sectional-study-of-sub-saharan-africa-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107121.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">179</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Wettability Properties of Pineapple Leaf Fibers and Banana Pseudostem Fibers Treated by Cold Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tatiana%20Franco">Tatiana Franco</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20A.%20Estupinan"> Hugo A. Estupinan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Banana pseudostem fiber (BPF) and pineapple leaf fiber (PLF) for their excellent mechanical properties and biodegradability characteristics arouse interest in different areas of research. F In tropical regions, where the banana pseudostem and the pineapple leaf are transformed into hard-to-handle solid waste, they can be low-cost raw material and environmentally sustainable in research for composite materials. In terms of functionality of this type of fiber, an open structure would allow the adsorption and retention of organic, inorganic and metallic species. In general, natural fibers have closed structures on their surface with intricate internal arrangements that can be used for the solution of environmental problems and other technological uses, however it is not possible to access their internal structure and sublayers, exposing the fibers in the natural state. An alternative method to chemical and enzymatic treatment are the processes with the plasma treatments, which are known to be clean, economical and controlled. In this type of treatment, a gas contained in a reactor in the form of plasma acts on the fiber generating changes in its structure, morphology and topography. This work compares the effects on fibers of PLF and BPF treated with cold argon plasma, alternating time and current. These fibers are grown in the regions of Antioquia-Colombia. The morphological, compositional and wettability properties of the fibers were analyzed by Raman microscopy, contact angle measurements, scanning electron microscopy (SEM) and atomic force microscopy analysis (AFM). The treatment with cold plasma on PLF and BPF allowed increasing its wettability, the topography and the microstructural relationship between lignin and cellulose. <p
