This study proposes a composite material developed from the biodegradable polymer PLA Ecovio® (polylactic acid - PLA) with natural sisal fibers, where the soybean ester was used as a plasticizer, which can aid in adhesion between the materials and fibers, making the most attractive final composite from an environmental point of view. The composites were obtained by extrusion. The materials tests were produced and submitted to biodegradation tests. Through the biodegradation tests, it can be seen that the biodegradable polymer composition with 5% sisal fiber presented about 12.4% more biodegradability compared to the polymer without fiber addition. It has also been found that the plasticizer was not a compatible with fibers and the polymer. Finally, fibers help to anticipate the decomposition process of the material when subjected to conditions of a landfill. Therefore, its intrinsic properties are not affected during its use, only the biodegradation process begins after its exposure to landfill conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocomposites" title="biocomposites">biocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=sisal" title=" sisal"> sisal</a>, <a href="https://publications.waset.org/abstracts/search?q=polilactic%20acid" title=" polilactic acid"> polilactic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=Polylactic%20Acid%20%28PLA%29" title=" Polylactic Acid (PLA)"> Polylactic Acid (PLA)</a> </p> <a href="https://publications.waset.org/abstracts/87364/biodegradability-evaluation-of-polylactic-acid-composite-with-natural-fiber-sisal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87364.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">249</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> Development of 4D Dynamic Simulation Tool for the Evaluation of Left Ventricular Myocardial Functions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deepa">Deepa</a>, <a href="https://publications.waset.org/abstracts/search?q=Yashbir%20Singh"> Yashbir Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Shi%20Yi%20Wu"> Shi Yi Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Friebe"> Michael Friebe</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Manuel%20R.%20S.%20Tavares"> Joao Manuel R.

The objective of the synthesis was to identify the most researched areas and the most used methodologies. Articles published in three Brazilian journals of Translation Studies, unpublished dissertations and theses were included in the analysis. Abstracts and the method sections of the papers were scrutinized. Sixty studies were analyzed, and overall results indicate that the research in Brazilian Sign Language has been fragmented in several areas such as linguistic aspects, facial expressions, subtitling, identity issues, bilingualism, and interpretation strategies. Concerning research methods, the synthesis reveals that most research is qualitative in nature. Moreover, results show that the cognitive aspects of Brazilian Sign Language seem to be poorly explored. Implications for a future research agenda are also discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brazilian%20sign%20language" title="Brazilian sign language">Brazilian sign language</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20methods" title=" qualitative methods"> qualitative methods</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20agenda" title=" research agenda"> research agenda</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a> </p> <a href="https://publications.waset.org/abstracts/91686/brazilian-sign-language-a-synthesis-of-the-research-in-the-period-from-2000-to-2017" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91686.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">34</span> Stabilization of the Bernoulli-Euler Plate Equation: Numerical Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carla%20E.%20O.%20de%20Moraes">Carla E.

For this, we consider a square plate subjected to a feedback/damping force distributed only in a subdomain. An algorithm for obtaining an approximate solution to this problem was proposed and implemented. The numerical method used was the Finite Difference Method. Numerical simulations were performed and showed the behavior of the solution, confirming the theoretical results that have already been proved in the literature. In addition, we studied the validation of the numerical scheme proposed, followed by an analysis of the numerical error; and we conducted a study on the decay of the energy associated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bernoulli-Euler%20plate%20equation" title="Bernoulli-Euler plate equation">Bernoulli-Euler plate equation</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulations" title=" numerical simulations"> numerical simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20decay" title=" energy decay"> energy decay</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20difference%20method" title=" finite difference method"> finite difference method</a> </p> <a href="https://publications.waset.org/abstracts/7035/stabilization-of-the-bernoulli-euler-plate-equation-numerical-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7035.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">416</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">33</span> Low-Cost VoIP University Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Henrique%20Rodrigues%20de%20Oliveira">Carlos Henrique Rodrigues de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Carlos%20Costa%20Fonseca"> Luis Carlos Costa Fonseca</a>, <a href="https://publications.waset.org/abstracts/search?q=Caio%20de%20Castro%20Torres"> Caio de Castro Torres</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Gusm%C3%A3o%20Pereira"> Daniel Gusmão Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Ricardo%20Souza%20Ripardo"> Luiz Ricardo Souza Ripardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Magno%20Castro%20Moraes"> Magno Castro Moraes</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Paula%20Ferreira%20Costa"> Ana Paula Ferreira Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Carlos%20Chaves%20Lima%20Junior"> Luiz Carlos Chaves Lima Junior</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurelianny%20Almeida%20da%20Cunha"> Aurelianny Almeida da Cunha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> VoIP University is a communication solution based on the IP protocol.

Considered it a semi-regenerative reformer, with four reactors in series intercalated with four furnaces, two heat exchanges, one product separator and one recycle compressor. A simplified reactional system was considered, involving only ten chemical compounds related through five reactions. The considered process was the applied to aromatics production (benzene, toluene, and xylene). The models developed to diverse equipment were interconnecting in a simulator that consists of a computer program elaborate in FORTRAN 77. The simulation of the global model representative of reformer unity achieved results that are compatibles with the literature ones. It was then possible to study the effects of operational variables in the products concentration and in the performance of the unity equipment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalytic%20reforming" title="catalytic reforming">catalytic reforming</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=petrochemical%20engineering" title=" petrochemical engineering"> petrochemical engineering</a> </p> <a href="https://publications.waset.org/abstracts/22923/naphtha-catalytic-reform-modeling-and-simulation-of-unity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22923.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">516</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">31</span> The Fake News Impact on the Public Policy Cycle: A Systemic Analysis through Documentary Survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aron%20Miranda%20Burgos">Aron Miranda Burgos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ergon%20Cugler%20de%20Moraes%20Silva"> Ergon Cugler de Moraes Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present article, it is observed that the constant advancement of issues related to misinformation impacts the guarantee of the public policy cycle.

Public policies are about what governments do or do not do, being an area that has grown worldwide, contributing through the knowledge of technologies and methodologies that monitor and evaluate the performance of public administrators. The information published on official government websites needs to provide for transparency and responsiveness of managers. Thus, transparency is a primordial factor for the execution of Accountability, providing, in this way, services to the citizen with the expansion of transparent, efficient, democratic information and that value administrative eco-efficiency. The ecologically balanced management of a Smart City must optimize environmental education, building a fairer society, which brings about equality in the use of quality environmental resources. Smart Cities add value in the construction of public management, enabling interaction between people, enhancing environmental education and the practical applicability of administrative eco-efficiency, fostering economic development and improving the quality of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accountability" title="accountability">accountability</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20education" title=" environmental education"> environmental education</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20public%20administration" title=" new public administration"> new public administration</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20cities" title=" smart cities"> smart cities</a> </p> <a href="https://publications.waset.org/abstracts/140750/the-public-law-studies-relationship-between-accountability-environmental-education-and-smart-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140750.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">29</span> A Proposal of Ontology about Brazilian Government Transparency Portal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Estela%20Mayra%20de%20Moura%20Vianna">Estela Mayra de Moura Vianna</a>, <a href="https://publications.waset.org/abstracts/search?q=Thiago%20Jos%C3%A9%20Tavares%20%C3%81vila"> Thiago José Tavares Ávila</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Morais%20Silva"> Bruno Morais Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Henrique%20Bezerra"> Diego Henrique Bezerra</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Henrique%20Gomes%20Silva"> Paulo Henrique Gomes Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Pedro%20da%20Silva"> Alan Pedro da Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Brazilian Federal Constitution defines the access to information as a crucial right of the citizen and the Law on Access to Public Information, which regulates this right. Accordingly, the Fiscal Responsibility Act, 2000, amended in 2009 by the “Law of Transparency”, began demanding a wider disclosure of public accounts for the society, including electronic media for public access. Thus, public entities began to create "Transparency Portals," which aim to gather a diversity of data and information. However, this information, in general, is still published in formats that do not simplify understanding of the data by citizens and that could be better especially available for audit purposes. In this context, a proposal of ontology about Brazilian Transparency Portal can play a key role in how these data will be better available. This study aims to identify and implement in ontology, the data model about Transparency Portal ecosystem, with emphasis in activities that use these data for some applications, like audits, press activities, social government control, and others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audit" title="audit">audit</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20transparency" title=" government transparency"> government transparency</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sector" title=" public sector"> public sector</a> </p> <a href="https://publications.waset.org/abstracts/14657/a-proposal-of-ontology-about-brazilian-government-transparency-portal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14657.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">508</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">28</span> Automatic Lead Qualification with Opinion Mining in Customer Relationship Management Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Radich">Victor Radich</a>, <a href="https://publications.waset.org/abstracts/search?q=Tania%20Basso"> Tania Basso</a>, <a href="https://publications.waset.org/abstracts/search?q=Regina%20Moraes"> Regina Moraes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lead qualification is one of the main procedures in Customer Relationship Management (CRM) projects. Its main goal is to identify potential consumers who have the ideal characteristics to establish a profitable and long-term relationship with a certain organization. Social networks can be an important source of data for identifying and qualifying leads since interest in specific products or services can be identified from the users’ expressed feelings of (dis)satisfaction. In this context, this work proposes the use of machine learning techniques and sentiment analysis as an extra step in the lead qualification process in order to improve it. In addition to machine learning models, sentiment analysis or opinion mining can be used to understand the evaluation that the user makes of a particular service, product, or brand. The results obtained so far have shown that it is possible to extract data from social networks and combine the techniques for a more complete classification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lead%20qualification" title="lead qualification">lead qualification</a>, <a href="https://publications.waset.org/abstracts/search?q=sentiment%20analysis" title=" sentiment analysis"> sentiment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=opinion%20mining" title=" opinion mining"> opinion mining</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=CRM" title=" CRM"> CRM</a>, <a href="https://publications.waset.org/abstracts/search?q=lead%20scoring" title=" lead scoring"> lead scoring</a> </p> <a href="https://publications.waset.org/abstracts/183496/automatic-lead-qualification-with-opinion-mining-in-customer-relationship-management-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183496.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">89</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">27</span> Public Governance in Brazil: The Perception of Professionals and Counselors of the Courts of Auditors on Transparency, Responsiveness and Accountability of Public Policies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paulino%20Varela%20Tavares">Paulino Varela Tavares</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lucia%20Romao"> Ana Lucia Romao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Public governance represents an articulated arrangement, dynamic and interactive, present in the exercise of authority aimed at strengthening the decision-making procedure in public administration with transparency, accountability, responsiveness and capable of to emerge control and social empowerment, to pursue and achieve the objectives efficiently and with the effectiveness desired for the collectivity, respecting the laws and provide social, institutional and economic equity in society.

In this context, the participation of society in the elaboration, execution, and control of public policies is prominent to strengthen public governance itself. With this, using a multidimensional approach with the application of two questionnaires to a universe of twenty Counselors of the Courts of Auditors (Brazil), twenty professionals of public administration (Brazil), twenty Government/Provincial Counselors (South Africa), and twenty South African professionals of public administration, the preliminary results indicate that the participation of civil society, for both countries, is very low in the elaboration, execution, and control of public policies. At the same time, about 70% of the answers obtained indicate, on average, three possible paths to increase the participation of civil society. With this, it is delineated that developing new horizons to strengthen both public policies how social participation is necessary, but, for both, it is important that governments and civil society, in their respective countries, have an awareness of the effective importance of this interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brazil" title="Brazil">Brazil</a>, <a href="https://publications.waset.org/abstracts/search?q=civil%20society" title=" civil society"> civil society</a>, <a href="https://publications.waset.org/abstracts/search?q=participation" title=" participation"> participation</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/120002/governance-and-public-policy-the-perception-of-civil-society-participation-in-brazil-and-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120002.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">145</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">25</span> Influence of Cure Degree in GO and CNT-Epoxy Nanocomposites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marina%20Borgert%20Moraes">Marina Borgert Moraes</a>, <a href="https://publications.waset.org/abstracts/search?q=Wesley%20Francisco"> Wesley Francisco</a>, <a href="https://publications.waset.org/abstracts/search?q=Filipe%20Vargas"> Filipe Vargas</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilmar%20Patroc%C3%ADnio%20Thim"> Gilmar Patrocínio Thim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, carbon nanotubes (CNT) and graphene oxide (GO), especially the functionalized ones, have been added to epoxy resin in order to increase the mechanical, electrical and thermal properties of nanocomposites.

The membrane reactor tries to minimize post-treatment steps, resulting in cost savings and enabling the competitiveness of biodiesel produced by homogeneous alkaline catalysis. This is due to the reaction and product separation may occur simultaneously. In order to evaluate the production of biodiesel from soybean oils using a tubular membrane reactor, a factorial experimental design was conducted (2³) to evaluate the influence of following variables: temperature (45 to 60 °C), catalyst concentration (0.5 to 1% by weight) and molar ratio of oil/methanol (1/6 to 1/9). In addition, the parametric sensitivity was evaluated by the analysis of variance and model through the response surface. The results showed a tendency of influence of the variables in the reaction conversion. The significance effect was higher for the catalyst concentration followed by the molar ratio of oil/methanol and finally the temperature. The best result was obtained under the conditions of 1% catalyst (KOH), molar ratio oil/methanol of 1/9 and temperature of 60 °C, resulting in an ester content of 99.07%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel%20production" title="biodiesel production">biodiesel production</a>, <a href="https://publications.waset.org/abstracts/search?q=factorial%20design" title=" factorial design"> factorial design</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20reactor" title=" membrane reactor"> membrane reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean%20oil" title=" soybean oil"> soybean oil</a> </p> <a href="https://publications.waset.org/abstracts/39575/evaluation-of-the-operating-parameters-for-biodiesel-production-using-a-membrane-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39575.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">377</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">23</span> A Comparison of Kinetic and Mechanical Properties between Graphene Oxide (GO) and Carbon Nanotubes (CNT)-Epoxy Nanocomposites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marina%20Borgert%20Moraes">Marina Borgert Moraes</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilmar%20Patrocinio%20Thim"> Gilmar Patrocinio Thim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is still unknown how the presence of nanoparticles such as graphene oxide (GO) or carbon nanotubes (CNT) influence the curing process and the final mechanical properties as well.

Seeds with mechanical damage at harvest time will be more susceptible to fungal and insect attack during storage, which will invariably reduce their vigor to the field, compromising uniformity and final stand performance. Harvesters, even the most modern ones, when not properly regulated or operated, can cause irreversible damages to the seeds, compromising even their commercialization. Therefore, the control of an efficient harvest is necessary in order to guarantee a good quality final product. In this work, the damage caused by two different harvesters (one rented, and another one) was evaluated, traveling in two speeds (4 and 8 km / h). The design was completely randomized in 2 x 2 factorial, with four replications. To evaluate the physiological quality seed germination and vigor tests were carried out over a period of six months. A multivariate analysis of Principal Components (PCA) and clustering allowed us to verify that the leased machine had better performance in the incidence of immediate damages in the seeds, but after a storage period of 6 months the vigor of these seeds reduced more than own machine evidencing that such a machine would bring more damages to the seeds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Glycine%20max%20%28L.%29" title="Glycine max (L.)">Glycine max (L.)</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster%20analysis" title=" cluster analysis"> cluster analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=PCA" title=" PCA"> PCA</a>, <a href="https://publications.waset.org/abstracts/search?q=vigor" title=" vigor "> vigor </a> </p> <a href="https://publications.waset.org/abstracts/65470/longevity-of-soybean-seeds-submitted-to-different-mechanized-harvesting-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65470.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">21</span> Governance and Public Policy: The Perception of Efficiency and Equility in Brazil and South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paulino%20V.%20Tavares">Paulino V.

With this, using a multidimensional approach with the application of three questionnaires to a universe of twenty Counselors of the Courts of Auditors (Brazil), twenty professionals of public administration (Brazil), twenty Government/Provincial Counselors (South Africa), and twenty South African professionals of public administration, the present work aims to capture what is the perception about the efficiency and equility of public policies in Brazil and South Africa. With this, up until now, 30 responses have been obtained, and the results indicate that, in Brazil, 65% affirm due to the inefficiency of public policies, 70% point out that they do not believe in the equility of these same policies. In South Africa, the results indicate that 45% believe in government efficiency, and, with regard to the equility of public policies, 65% do not believe. In Brazil, the research reveals at least three reasons for this result, that is, lack of planning, lack of clear objectives of public policies, and lack of information on the part of society, while in South Africa, so far, research has not identified a specific reason for this result. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efficiency" title="efficiency">efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=equility" title=" equility"> equility</a>, <a href="https://publications.waset.org/abstracts/search?q=governance" title=" governance"> governance</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20policy" title=" public policy"> public policy</a> </p> <a href="https://publications.waset.org/abstracts/120007/governance-and-public-policy-the-perception-of-efficiency-and-equility-in-brazil-and-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120007.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">128</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">20</span> Impact of Integrated Signals for Doing Human Activity Recognition Using Deep Learning Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milagros%20Ja%C3%A9n-Vargas">Milagros Jaén-Vargas</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Garc%C3%ADa%20Mart%C3%ADnez"> Javier García Martínez</a>, <a href="https://publications.waset.org/abstracts/search?q=Karla%20Miriam%20Reyes%20Leiva"> Karla Miriam Reyes Leiva</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Fernanda%20Trujillo-Guerrero"> María Fernanda Trujillo-Guerrero</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Fernandes"> Francisco Fernandes</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C3%A9rgio%20Barroso%20Gon%C3%A7alves"> Sérgio Barroso Gonçalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Tavares%20Silva"> Miguel Tavares Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Sim%C3%B5es%20Lopes"> Daniel Simões Lopes</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Javier%20Serrano%20Olmedo"> José Javier Serrano Olmedo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human Activity Recognition (HAR) is having a growing impact in creating new applications and is responsible for emerging new technologies.

Hence, the use of these dispositive is less invasive and the person is more comfortable. In this study, a database that includes three activities is used. The activities were acquired from inertial measurement unit sensors (IMU) and motion capture systems (MOCAP). The main objective is differentiating the performance from four Deep Learning (DL) models: Deep Neural Network (DNN), Convolutional Neural Network (CNN), Recurrent Neural Network (RNN) and hybrid model Convolutional Neural Network-Long Short-Term Memory (CNN-LSTM), when considering acceleration, velocity and position and evaluate if integrating the IMU acceleration to obtain velocity and position represent an increment in performance when it works as input to the DL models. Moreover, compared with the same type of data provided by the MOCAP system. Despite the acceleration data is cleaned when integrating, results show a minimal increase in accuracy for the integrated signals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HAR" title="HAR">HAR</a>, <a href="https://publications.waset.org/abstracts/search?q=IMU" title=" IMU"> IMU</a>, <a href="https://publications.waset.org/abstracts/search?q=MOCAP" title=" MOCAP"> MOCAP</a>, <a href="https://publications.waset.org/abstracts/search?q=acceleration" title=" acceleration"> acceleration</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity" title=" velocity"> velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=position" title=" position"> position</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20maps" title=" feature maps"> feature maps</a> </p> <a href="https://publications.waset.org/abstracts/167055/impact-of-integrated-signals-for-doing-human-activity-recognition-using-deep-learning-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167055.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">100</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">19</span> Prescribed Organization of Nursing Work and Psychosocial Risks: A Cross-Sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katerine%20Moraes%20dos%20Satons">Katerine Moraes dos Satons</a>, <a href="https://publications.waset.org/abstracts/search?q=Gisele%20Massante%20Peixoto%20Tracera"> Gisele Massante Peixoto Tracera</a>, <a href="https://publications.waset.org/abstracts/search?q=Regina%20C%C3%A9lia%20Gollner%20Zeitoune"> Regina Célia Gollner Zeitoune</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To analyze the psychosocial risks related to the organization of nursing work in outpatient clinics of university hospitals. Cross-sectional epidemiological study developed in 11 outpatient units linked to the three public universities of the city of Rio de Janeiro, Brazil. Participants were 388 nursing professionals who worked in patient care at the time of the research. Data were collected from July to December 2018, using a self-applicable instrument. A questionnaire was used for sociodemographic, occupational and health characterization, and the Work Organization Scale. The bivariate analyses were performed using the odds ratio (OR), with a confidence interval of 95%, significance level of 5%. The organization of nursing work received an assessment of medium psychosocial risk by the professionals participating in the research, demanding interventions in the short and medium term. There was no association between sociodemographic, occupational and health characteristics and the organization of outpatient work. Interventional measures should be performed in the psychosocial risk factors presented in this research, with a view to improving the work environment, so that the importance of maintaining satisfactory material conditions is considered, as well as the adequate quantity of human resources. In addition, it aims to expand the spaces of nursing participation in decision- making, strengthening its autonomy as a profession. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=occupational%20risks" title="occupational risks">occupational risks</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing" title=" nursing"> nursing</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing%20team" title=" nursing team"> nursing team</a>, <a href="https://publications.waset.org/abstracts/search?q=worker%E2%80%99s%20health" title=" worker’s health"> worker’s health</a>, <a href="https://publications.waset.org/abstracts/search?q=psychosocial%20risks" title=" psychosocial risks"> psychosocial risks</a> </p> <a href="https://publications.waset.org/abstracts/157676/prescribed-organization-of-nursing-work-and-psychosocial-risks-a-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157676.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">97</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">18</span> Comparative Study for Biodiesel Production Using a Batch and a Semi-Continuous Flow Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20S.%20L.%20Andrade">S.

This reaction can occur in the presence of acid catalysts, alkali, or enzyme. Currently, for industrial processes, biodiesel is produced by alkaline route. The alkali most commonly used in these processes is hydroxides and methoxides of sodium and potassium. In this work, biodiesel production was conducted in two different systems. The first consisted of a batch reactor operating with a traditional washing system and the second consisted of a semi-continuous flow reactor operating with a membrane separation system. Potassium hydroxides was used as catalyst at a concentration of 1% by weight, the molar ratio oil/alcohol was 1/9 and temperature of 55 °C. Tests were performed using soybeans and palm oil and the ester conversion results were compared for both systems. It can be seen that the results for both oils are similar when using the batch reator or the semi-continuous flow reactor. The use of the semi-continuous flow reactor allows the removal of the formed products. Thus, in the case of a reversible reaction, with the removal of reaction products, the concentration of the reagents becomes higher and the equilibrium reaction is shifted towards the formation of more products. The higher conversion to ester with soybean and palm oil using the batch reactor was approximately 98%. In contrast, it was observed a conversion of 99% when using the same operating condition on a semi-continuous flow reactor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title="biodiesel">biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=batch%20reactor" title=" batch reactor"> batch reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-continuous%20flow%20reactor" title=" semi-continuous flow reactor"> semi-continuous flow reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=transesterification" title=" transesterification"> transesterification</a> </p> <a href="https://publications.waset.org/abstracts/39572/comparative-study-for-biodiesel-production-using-a-batch-and-a-semi-continuous-flow-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39572.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">384</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">17</span> The UNESCO Management Plan for Urban Heritage Sites: A Critical Review of Olinda and Porto, in Brazil and Portugal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francine%20Morales%20Tavares">Francine Morales Tavares</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Alberto%20Rio%20Fernandes"> Jose Alberto Rio Fernandes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The expanding concept of Heritage and the increased relevance of how heritage places relate to their surroundings is associated with an important shift in public heritage policies and how they consider the development of cities and communities, with an increasingly relevant role of management. Within the current discussions, management plans, mandatory since the year 2005 in areas classified by UNESCO as World Heritage, it is a tool for the reconciliation of cultural heritage demands with the needs of multiple users of a certain area, being especially critical in the case of urban areas with intense touristic pressure. Considering the transformations of the heritage policy management model, this paper discusses the practices on the integration of cultural heritage in urban policies through indicators which were selected from resource manual 'Managing Cultural World Heritage (2013)' and analyzed two case studies: The Management Plan of the Historic Centre of Porto (Portugal) and The Management Plan for the Historic Site of Olinda (Brazil). The empirical evidence concluded that for the historic centre of Porto the increase of tourism is the main aim driver in the management plan, with positive and negative aspects on the heritage management point of view, unlike Olinda, where the plan for the development of local urban policies was identified as essential. Plans also differ in form, content and process but coincide on being unaligned with committed local political leaders’ agendas, with the consequent misunderstandings between theory and practice, planning and management, and critically missing in the field integration of urban policies. Therefore, more debate about management plans, more efficient tools and also, appropriate methodologies to correlate cultural heritage and urban public policy are still lacking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=world%20heritage" title="world heritage">world heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=management%20plan" title=" management plan"> management plan</a>, <a href="https://publications.waset.org/abstracts/search?q=planning" title=" planning"> planning</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20policies" title=" urban policies"> urban policies</a> </p> <a href="https://publications.waset.org/abstracts/113859/the-unesco-management-plan-for-urban-heritage-sites-a-critical-review-of-olinda-and-porto-in-brazil-and-portugal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113859.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">16</span> S.

Pollinators not only increase crop yield but also improve quality of produce as well. The present investigation is therefore, an endeavor to assess the visitation pattern of honeybees, Apis florea (Hymenopterae: Apidae) in sunflower (Helianthus annuus L.). The current research trial was carried out at New Developmental Farm (NDF), The University of Agriculture Peshawar, (34.01° N, 71.53° E) Khyber Pakhtunkhwa-Pakistan during 2012 and 2013. Different observations on the foraging behavior of A. florea’s individuals were made from 0800 hr in the morning and continued until 1800 hr in the evening. Hence, total duration of foraging activity of A. florea individuals was comprised of 10 hours. It was found that two peaks of visitation/foraging occurred between 1400 to 1600 hr of the day. First peak of foraging was recorded at 1600hr, where 15 individuals of honeybees/3 m2 were counted to be engaged in foraging sunflower blooms. Second peak visitation was recorded with a total of 12 bees/3 m2 at 1400 hrs of the day. Visitations of A. florea were observed to its minimum intensity of only 07 individuals during late hours of the day as evening approached after 1800 hrs. Similarly, due to more number of pollens and nectars on flowers, high frequency of A. florea were found engaged in foraging during 20th and 25th day after initiation of blooms on sunflower. Minimum numbers of honeybees were recorded during initial and very last days of flowering due to less number of plants with blooms and less availability of pollen and nectar on flowers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apis%20florea" title="apis florea">apis florea</a>, <a href="https://publications.waset.org/abstracts/search?q=days%20after%20flowering" title=" days after flowering"> days after flowering</a>, <a href="https://publications.waset.org/abstracts/search?q=daily%20hours" title=" daily hours"> daily hours</a>, <a href="https://publications.waset.org/abstracts/search?q=sunflower" title=" sunflower"> sunflower</a>, <a href="https://publications.waset.org/abstracts/search?q=visitation%20pattern" title=" visitation pattern "> visitation pattern </a> </p> <a href="https://publications.waset.org/abstracts/40011/s-s-l-andrade-e-a-souza-l-c-l-santos-c-moraes-a-k-c-l-lobato" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40011.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">637</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">15</span> Flow-Oriented Incentive Spirometry in the Reversal of Diaphragmatic Dysfunction in Bariatric Surgery Postoperative Period</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eli%20Maria%20Forti-Pazzianotto">Eli Maria Forti-Pazzianotto</a>, <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Moraes%20Da%20Costa"> Carolina Moraes Da Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Faleiros%20Berteli%20Merino"> Daniela Faleiros Berteli Merino</a>, <a href="https://publications.waset.org/abstracts/search?q=Maura%20Rigoldi%20Sim%C3%B5es%20Da%20Rocha"> Maura Rigoldi Simões Da Rocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Irineu%20Rasera-Junior"> Irineu Rasera-Junior</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is no conclusive evidence to support the use of one type or brand of incentive espirometry over others. The decision as to which equipment is best, have being based on empirical assessment of patient acceptance, ease of use, and cost. The aim was to evaluate the effects of use of two methodologies of breathing exercises, performed by flow-oriented incentive spirometry, in the reversal of diaphragmatic dysfunction in postoperative bariatric surgery. 38 morbid obese women were selected. Respiratory muscle strength was evaluated through the nasal inspiratory pressure (NIP), and the respiratory muscles endurance, through incremental test by measurement of sustained maximal inspiratory pressure (SMIP). They were randomized in 2 groups: 1- Respiron® Classic (RC) the inspirations were slow, deep and sustained for as long as possible (5 sec). 2- Respiron® Athletic1 (RA1) - the inspirations were explosive, quick and intense, raising balls by the explosive way. 6 sets of 15 repetitions with intervals of 30 to 60 seconds were performed in groups. At the end of the intervention program (second PO), the volunteers were reevaluated. The groups were homogeneous with regard to initial assessment. However on reevaluating there was a significant decline of the variable PIN (p= < 0.0001) and SMIP (p=0.0004) in RC. In the RA1 group there was a maintenance of SMIP (p=0.5076) after surgery. The use of the Respiron Athletic 1, as well as the methodology of application used, can contribute positively to preserve the inspiratory muscle endurance and improve the diaphragmatic dysfunction in postoperative period. <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=incentive%20spirometry" title=" incentive spirometry"> incentive spirometry</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20muscle" title=" respiratory muscle"> respiratory muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=physiotherapy" title=" physiotherapy"> physiotherapy</a> </p> <a href="https://publications.waset.org/abstracts/27079/flow-oriented-incentive-spirometry-in-the-reversal-of-diaphragmatic-dysfunction-in-bariatric-surgery-postoperative-period" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27079.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">14</span> Multi-Criterial Analysis: Potential Regions and Height of Wind Turbines, Rio de Janeiro, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudio%20L.%20M.%20Souza">Claudio L.

This work presents results obtained by multi-criteria decision analysis, and it establishes a hierarchy, regarding the installation of wind farms, among geopolicy regions in the state of ‘Rio de Janeiro’, Brazil: ‘Regiao Norte-RN’, ‘Regiao dos Lagos-RL’ and ‘Regiao Serrana-RS’. The wind regime map indicates only these three possible regions with an average annual wind speed of above of 6.0 m/s. The method applied was the Analytical Hierarchy Process-AHP, designed to prioritize and rank the three regions based on four criteria as follows: 1) potential of the site and average wind speeds of above 6.0 ms-¹, 2) average land value, 3) distribution and interconnection to electric network with the highest number of electricity stations, and 4) accessibility with proximity and quality of highways and flat topography. The values of energy generation were calculated for wind turbines 50, 75, and 100 meters high, considering the production of site (GWh/Km²) and annual production (GWh). The weight of each criterion was attributed by six engineers and by analysis of Road Map, the Map of the Electric System, the Map of Wind Regime and the Annual Land Value Report. The results indicated that in 'RS', the demand was estimated at 2,000 GWh, so a wind farm can operate efficiently in 50 m turbines. This region is mainly mountainous with difficult access and lower land value. With respect to ‘RL’, the wind turbines have to be installed at a height of 75 m high to reach a demand of 6,300 GWh. This region is very flat, with easy access, and low land value. Finally, the ‘NR’ was evaluated as very flat and with expensive lands. In this case, wind turbines with 100 m can reach an annual production of 19,000 GWh. In this Region, the coast area was classified as of greater logistic, productivity and economic potential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AHP" title="AHP">AHP</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20energy" title=" wind energy"> wind energy</a> </p> <a href="https://publications.waset.org/abstracts/88888/multi-criterial-analysis-potential-regions-and-height-of-wind-turbines-rio-de-janeiro-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88888.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Histological Characteristics of the Organs of Adult Zebrafish as a Biomarker for the Study of New Drugs with Effect on the Snake Venom of Bothrops alternatus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Carlos%20Tavares%20Carvalho">Jose Carlos Tavares Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Hady%20Keita"> Hady Keita</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanna%20Rocha%20Santana"> Giovanna Rocha Santana</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Victor%20Ferreira%20Dos%20Santos"> Igor Victor Ferreira Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesus%20Rafael%20Rodriguez%20Amado"> Jesus Rafael Rodriguez Amado</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariadna%20Lafourcade%20Prada"> Ariadna Lafourcade Prada</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Maciel%20Ferreira"> Adriana Maciel Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Helison%20Oliveira"> Helison Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Summary: As animal model, zebrafish can be a good opportunity to establish a profile of tissue alteration caused by Bothrops alternatus venom and to screen new anti-venom drugs. Objective: To establish tissue biomarkers from zebrafish injected by snake venom and elucidate the use of glucocorticoids in ophidic accidents. Materials and Methods: The Danio rerio fish were randomly divided into four groups: control group, venom group, Dexamethasone1h before venom injected group and Dexamethasone 1 h after venom injected group. The concentration of Bothrops alternatus venom was 0.13 mg/ml and the fish received 20µl/Fish. The Body weight measurement and histological characteristics of gills, kidneys, liver, and intestine were determinate. Results: Physical analysis shows necrosis accompanied by inflammation in animals receiving the Bothrops alternatus venom. Significant difference was observed in the variation of weight between the control group, and the groups received the venom (t student test, p < 0.05). The average histological alterations index of gill, liver, kidney or intestine was statistically higher in animals received the venom (t Student test, p < 0.05). The alterations were lower in the groups that received Dexamethasone 1h before and after venom injected compared to the group that received only the venom. Dexamethasone 1h before venom injected group had minor histopathological alterations. Conclusion: The organs of zebrafish may be a tissue biomarker of alterations from Bothrops alternatus venom and dexamethasone reduced the damage caused by this venom in the organs studied, which may suggest the use of zebrafish as animal model for research related to screening new drug against snake venom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zebrafish" title="zebrafish">zebrafish</a>, <a href="https://publications.waset.org/abstracts/search?q=snake%20venom" title=" snake venom"> snake venom</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker" title=" biomarker"> biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=drugs" title=" drugs"> drugs</a> </p> <a href="https://publications.waset.org/abstracts/53757/histological-characteristics-of-the-organs-of-adult-zebrafish-as-a-biomarker-for-the-study-of-new-drugs-with-effect-on-the-snake-venom-of-bothrops-alternatus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53757.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">328</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">12</span> Post-Anesthetic Recovery: The Best Moment to Apply Positive Pressure in Airway in Postoperative Bariatric Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eli%20Maria%20Pazzianotto-Forti">Eli Maria Pazzianotto-Forti</a>, <a href="https://publications.waset.org/abstracts/search?q=Patr%C3%ADcia%20Brigatto"> Patrícia Brigatto</a>, <a href="https://publications.waset.org/abstracts/search?q=Let%C3%ADcia%20Baltieri"> Letícia Baltieri</a>, <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Moraes%20Da%20Costa"> Carolina Moraes Da Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Maura%20Rigoldi%20Simoes%20Da%20Rocha"> Maura Rigoldi Simoes Da Rocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Irineu%20Rasera%20Jr"> Irineu Rasera Jr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The application of positive pressure in airway can contribute to the restoration of lung volumes, capacities and prevent respiratory complications. The aim was to investigate the use of Bilevel Positive Airway Pressure (BIPAP) in morbidly obese in two moments in postoperative bariatric surgery: In the post-anesthetic recovery (PAR) and on the 1st postoperative day (1stPO). Twenty morbidly obese, aged between 25 and 55 years, underwent pulmonary function test and chest X-ray preoperatively and on the day of discharge (2nd day after surgery). They were randomly allocated in groups. GPAR: received BIPAP treatment in PAR, for an hour and G1stPO: received BIPAP for one hour, on the 1stPO. There were significant reductions in slow vital capacity (SVC) (p=0.0007), inspiratory reserve volume (IRV) (p=0.0016) and forced vital capacity (FVC) (p=0.0013) in the postoperative in GPAR and the expiratory reserve volume (ERV) remained (p=0.4446). In the G1stPO, there were significant reductions for: SVC p=<0.0001, ERV p=0.0191, IRV p= 0.0026 and FVC p=<0.0001. Comparing between groups, the SVC (p=0.0027) and FVC (p=0.0028) showed significant difference between the treatments. However, the GPAR showed fewer declines of these capacities. To the ERV (p= 0.1646) and IRV (p=0.3973) there was no significant difference between groups. The atelectasis prevalence was 10% for the GPAR and 30% for G1stPO, with significant difference between the proportions (p = 0.0027). The lowest reduction in SVC and FVC happens when positive pressure is applied in PAR. Thus, the use of BIPAP in the PAR can promote a restoration of ERV and contribute to the reduction of atelectasis.

Its basic principle is to place cells on a scaffold capable of promoting cell functions, and for this purpose, polymeric nanoparticles have been successfully used due to the ability of some macro chains to mimic the extracellular matrix and influence cell functions. In general, nanoparticles require surface chemical modification to achieve cell adhesion, and recent advances in their synthesis include methods for modifying the ligand density and distribution onto nanoparticles surface. However, this work reports the development of biodegradable polymeric nanoparticles capable of promoting cellular adhesion without any surface chemical modification by ligands. Biocompatible and biodegradable nanoparticles based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) were synthesized by solvent evaporation method. The produced nanoparticles were small in size (85 and 125 nm) and colloidally stable against time in aqueous solution. Morphology evaluation showed their spherical shape with small polydispersity. Human osteoblast-like cells (MG63) were cultured in the presence of PHBHV nanoparticles, and growth kinetics were compared to those grown on tissue culture polystyrene (TCPS). Cell attachment on non-tissue culture polystyrene (non-TCPS) pre-coated with nanoparticles was assessed and compared to attachment on TCPS. These findings reveal the potential of PHBHV nanoparticles for cell adhesion and growth, without requiring a matrix ligand to support cells, to be used as scaffolds, in tissue engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title="tissue engineering">tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=PHBHV" title=" PHBHV"> PHBHV</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cells" title=" stem cells"> stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=cellular%20attachment" title=" cellular attachment"> cellular attachment</a> </p> <a href="https://publications.waset.org/abstracts/81789/engineering-ligand-free-biodegradable-based-nanoparticles-for-cell-attachment-and-growth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81789.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">211</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Attitudes Towards Immigrants: Evidence from Veterans of Colonial Wars in Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Margarida%20Matos">Margarida Matos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Pereira%20dos%20Santos"> João Pereira dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Tavares"> José Tavares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anti-minority discrimination is a persistent phenomenon with long-run effects. While there is a vast literature in economics and psychology that shows that personality and beliefs are not fixed and can be altered by experience, particularly in the so-called impressionable years in early adulthood, less is known about the long-lasting impacts of major events occurring during this time on minority attitudes. In this paper, we study the impact of serving in the military on long-term attitudes towards minorities. For many, military conscription and serving in war are unique life-shaping events. In the context of military service, individuals from different socioeconomic backgrounds interact and learn with each other, potentially changing their views and attitudes in a persistent manner. A prominent theory about the change of attitudes is the contact theory. It suggests that prejudice can be decreased if members of the groups interact with one another. The present paper adds to the literature by providing evidence from a more complicated setting involving the exposure to combat. We study the attitudes of veterans of the Portuguese Colonial War between 1961 and 1974, what was the latest war between African independence movements and Europeans. More than 70 percent of military age Portuguese men were drafted every year and sent to fight in Africa in the widest draft in post-World War II Western Europe. The contact between Portuguese and African soldiers was both cooperative as well as adversarial. Portuguese fought against but also alongside locally recruited African men, who represented half of the Portuguese contingent for substantial periods. We use data from the European Social Survey to identify Portuguese citizens likely to have been drafted and were send to fight in the former Portuguese colonies in Africa. We show that men likely to have fought in African wars are more accepting of immigrants than women of their same cohort, as well as than males from younger and older cohorts. The use of corresponding cohorts from Spain as placebo tests confirms our results. Our findings also hold in a regression discontinuity design setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attitudes"
