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">506</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">441</span> The Regulation on Human Exposure to Electromagnetic Fields for Brazilian Power System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Manoel%20Olivera%20Da%20Silva">Hugo Manoel Olivera Da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Silva%20Th%C3%A9%20Pontes"> Ricardo Silva Thé Pontes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, is presented an analysis of the Brazilian regulation on human exposure to electromagnetic fields, which provides limits to electric fields, magnetic and electromagnetic fields.

Two forms of applications of the ultrasound were evaluated aiming to increase reaction rates, wherein the use of probe ultrasound associated with the use of surfactant to pre-emulsify the substrate showed the best results. Two different reaction periods were found: the first where the ultrasound has great influence on reaction rates, and the second where ultrasound influence is minimal. Studies on the time of pre-emulsification, surfactant concentration and enzyme concentration showed that the initial rate of hydrolysis depends on the interfacial area between the oil phase and the aqueous phase containing the enzyme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=specific%20enzyme" title="specific enzyme">specific enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20fatty%20acids" title=" free fatty acids"> free fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=Hydrolysis" title=" Hydrolysis"> Hydrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lecitase%20ultra" title=" lecitase ultra"> lecitase ultra</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/20337/effect-of-ultrasound-on-the-hydrolysis-of-soy-oil-catalyzed-by-13-specific-lipase-abstract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20337.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">578</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">438</span> Energy Efficient Heterogeneous System for Wireless Sensor Networks (WSN)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Anderson%20Rodrigues%20de%20Souza">José Anderson Rodrigues de Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Teles%20de%20Sales%20Bezerra"> Teles de Sales Bezerra</a>, <a href="https://publications.waset.org/abstracts/search?q=Saulo%20Aislan%20da%20Silva%20Eleuterio"> Saulo Aislan da Silva Eleuterio</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeronimo%20Silva%20Rocha">Jeronimo Silva Rocha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mobile devices are increasingly occupying sectors of society and one of its most important features is mobility.

Therefore, this paper explores the best practices of HRM and seeks to understand the level of participation in the development of these practices by human resources managers in the hospitality industry and compare it with other industries. Thus, the study compared the HRM practices of companies in the hospitality sector with HRM practices of companies in other sectors, and identifies the main differences between their HRM practices. The results show that the most frequent HRM practices in all companies, independently of its sector of activity, are hiring and training. When comparing hospitality sector with other sectors of activity, some differences were noticed, namely in the adoption of the practices of communication and information sharing, and of recruitment and selection.

This memory-related and feeling-oriented food is one of the treasures common to all Brazilians. It is mandatory to mention its Portuguese roots for the use of honey, as well as sugar cane and its countless possibilities. This work will show that this heritage is predominantly Portuguese, born in Portuguese convents and that it crossed the Atlantic. Through a historical survey, visits to mining towns known for their sweet culture and material collected in these places, we present the protagonists of this journey of flavors: the Portuguese cake makers (boleiras), who brought the knowledge, ingredients, and the dream of a better life in the crowded mines of gold and opportunities, helping to form a new Minas Gerais knowledge with their delicacies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sweets%20from%20portugal" title="sweets from portugal">sweets from portugal</a>, <a href="https://publications.waset.org/abstracts/search?q=convent%20sweets" title=" convent sweets"> convent sweets</a>, <a href="https://publications.waset.org/abstracts/search?q=minas%20gerais" title=" minas gerais"> minas gerais</a>, <a href="https://publications.waset.org/abstracts/search?q=brazil" title=" brazil"> brazil</a> </p> <a href="https://publications.waset.org/abstracts/147936/portuguese-influence-on-minas-gerais-dessert-culinary-during-brazil-colonization-period" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147936.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">169</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">435</span> Vieira Da Silva&#039;s Tiles at Universidade Federal Rural Do Rio de Janeiro: A Conservation and Restoration Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Anselmo%20Oliveira">Adriana Anselmo Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present project showcases a tile work from the Franco-Portuguese artist Maria Helena Vieira da Silva (1908-1992). It is a set of 8 panels composed of figurative and geometric tiles, with extra tiles framing nearby doors and windows in a study room in the (UFRRJ, Universidade Federal Rural do Rio de Janeiro). The aforementioned work was created between 1942 and 1943, during the artist's 6 year exile in the Brazilian city. This one-of-a-kind tileset was designed and made by Vieira da Silva between 1942 and 1943. Over the years, several units were lost, which led to their replacement in the nineties. However, these replacements don't do justice to the original work of art. In 2007, a project was initiated to fully repair and maintain the set. Three panels are removed and restored, but the project is halted. To this day, the three fully restored panels remain in boxes. In 2016 a new restoration project is submitted by the (Faculdade de Belas Artes da Universidade de Lisboa) in collaboration with de (Fundacão Árpád Szenes-Vieira da Silva). There are many varied opinions on restoring and conserving older pieces of art, however, we have the moral duty to safeguard the original materials used by the artist along with the artists original vision and also to care for the future generations of students who will use the space in which the tile-work was inserted. Many tiles have been replaced by white tiles, tiles with a divergent colour pallet and technique, and in a few cases, the incorrect place or way around. These many factors make it increasingly difficult to maintain the artists original vision and destroy and chance of coherence within the artwork itself. The conservative technician cannot make new images to fill the empty spaces or mark the remaining images with their own creative input. with reliable photographic documentation that can provide us with the necessary vision to allow us to proceed with an accurate reconstruction, we have the obligation to proceed and return the piece of art to its true form, as in its current state, it is impossible to maintain its original glory. Using the information we have, we must find a way to differentiate the original tiles from the reconstructions in order to recreate and reclaim the original message from the artist. The objective of this project is to understand the significance of tiles in Vieira da Silva's art as well as the influence they had on the artist's pictorial language since the colour definition on tile work is vastly different from the painting process as the materials change during their merger. Another primary goal is to understand what the previous interventions achieved besides increasing the artworks durability. The main objective is to submit a proposal that can salvage the artist's visual intention and supports it for posteriority. In summary, this proposal goes further than the usual conservative interventions as it intends to recreate the original artistic worth, prioritising the aesthetics and keeping its soul alive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vieira%20da%20Silva" title="Vieira da Silva">Vieira da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=tiles" title=" tiles"> tiles</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=restoration" title=" restoration"> restoration</a> </p> <a href="https://publications.waset.org/abstracts/137916/vieira-da-silvas-tiles-at-universidade-federal-rural-do-rio-de-janeiro-a-conservation-and-restoration-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137916.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">156</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">434</span> Nazi Experiments during World War II: Dismal Period for Bioethics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catharina%20O.%20Vianna%20Dias%20da%20Silva">Catharina O.

The method was based on the bibliographic review of articles published in databases such as SciELO and Pubmed. In the discussion, historical and humanistic aspects that contributed to the construction of a genocidal culture practiced during this period were analyzed. Additionally, an ethical question arises: should the information acquired during this dark period be used by science? After analysis, it was found that these Nazi experiments went over medical and ethical principles, being a deplorable milestone in history. It was also concluded that, although they generated potentially 'useful' results in the scientific field, they should be discarded as an ethical question of principle, of never daring to validate such a deplorable way of obtaining knowledge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazism" title="Nazism">Nazism</a>, <a href="https://publications.waset.org/abstracts/search?q=bioethics" title=" bioethics"> bioethics</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20experimentation" title=" human experimentation"> human experimentation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=genocide" title=" genocide"> genocide</a>, <a href="https://publications.waset.org/abstracts/search?q=torture" title=" torture"> torture</a>, <a href="https://publications.waset.org/abstracts/search?q=medicine" title=" medicine"> medicine</a> </p> <a href="https://publications.waset.org/abstracts/133246/nazi-experiments-during-world-war-ii-dismal-period-for-bioethics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133246.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">171</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">433</span> Geographic Information System Applications in Prioritizing Karlahi Forest Reserve Area for Conservation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Hyellamada%20Jerry">Samuel Hyellamada Jerry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focused on assessing conservation priorities within the Karlahi Forest Reserve of Fufore Local Government in Adamawa State. The main objective was to identify specific areas within the forest reserve that require immediate conservation attention. The research employed remote sensing and GIS techniques to achieve this goal. By overlaying the IDRIS Silva module results, a spatial distribution map was generated, highlighting the cumulative priority areas within and outside the forest. Among the total vegetated area of 26.38 km² in the Karlahi Forest Reserve, the analysis revealed that 16.16 km² were classified as high-priority conservation zones. Additionally, 4.59 km² and 5.63 km² were identified as medium and low-priority areas, respectively. In light of these findings, it is recommended that conservation efforts incorporate detailed land cover information and regular assessments of species diversity. Furthermore, strict adherence to national and state policies regarding forest reserves and parks is crucial for effective conservation management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=priority" title="priority">priority</a>, <a href="https://publications.waset.org/abstracts/search?q=Karlahi" title=" Karlahi"> Karlahi</a>, <a href="https://publications.waset.org/abstracts/search?q=forest" title=" forest"> forest</a>, <a href="https://publications.waset.org/abstracts/search?q=reserve" title=" reserve"> reserve</a>, <a href="https://publications.waset.org/abstracts/search?q=IDRISI%20Silva" title=" IDRISI Silva"> IDRISI Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20diversity" title=" species diversity"> species diversity</a> </p> <a href="https://publications.waset.org/abstracts/178549/geographic-information-system-applications-in-prioritizing-karlahi-forest-reserve-area-for-conservation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178549.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">432</span> In vitro Bioacessibility of Phenolic Compounds from Fruit Spray Dried and Lyophilized Powder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Beres">Carolina Beres</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurine%20Da%20Silva"> Laurine Da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Danielle%20Pereira"> Danielle Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Ribeiro"> Ana Ribeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Renata%20Tonon"> Renata Tonon</a>, <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Mellinger-Silva"> Caroline Mellinger-Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Karina%20Dos%20Santos"> Karina Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Flavia%20Gomes"> Flavia Gomes</a>, <a href="https://publications.waset.org/abstracts/search?q=Lourdes%20Cabral"> Lourdes Cabral</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The health benefits of bioactive compounds such as phenolics are well known.

Juçara had a higher anthocianins bioacessibility (17.16%) when compared to grape pomace (2.08%). The opposite result was found for total phenolic compound, where the higher bioacessibility was for grape (400%). The phenolic compound increase indicates a more accessible compound in the human gut.

As the biggest producer of soy in the world and a major producer of coffee, sugar cane and citrus fruits, Brazil is a large consumer of phosphate. Brazilian&rsquo;s phosphate ores are predominantly from igneous rocks showing a complex mineralogy, associated with carbonites and oxides, typically iron, silicon and barium. The adopted industrial concentration circuit for this type of ore is a mix between magnetic separation (both low and high field) to remove the magnetic fraction and a froth flotation circuit composed by a reverse flotation of apatite (barite&rsquo;s flotation) followed by direct flotation circuit (rougher, cleaner and scavenger circuit). Since the 70&rsquo;s fatty acids obtained from vegetable oils are widely used as lower-cost collectors in apatite froth flotation. This is a very effective approach to the apatite family of minerals, being that this type of collector is both selective and efficient (high recovery). This paper presents <em>Jatropha curcas</em> <em>L.</em> oil (JCO) as a renewable and sustainable source of fatty acids with high selectivity in froth flotation of apatite. JCO is considerably rich in fatty acids such as linoleic, oleic and palmitic acid. The experimental campaign involved 216 tests using a modified Hallimond tube and two different minerals (apatite and quartz). In order to be used as a collector, the oil was saponified. The results found were compared with the synthetic collector, Fotigam 5806 produced by Clariant, which is composed mainly by soy oil. JCO showed the highest selectivity for apatite flotation with cold saponification at pH 8 and concentration of 2.5 mg/L. In this case, the mineral recovery was around 95%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=froth%20flotation" title="froth flotation">froth flotation</a>, <a href="https://publications.waset.org/abstracts/search?q=jatropha%20curcas" title=" jatropha curcas"> jatropha curcas</a>, <a href="https://publications.waset.org/abstracts/search?q=microflotation" title=" microflotation"> microflotation</a>, <a href="https://publications.waset.org/abstracts/search?q=selectivity" title=" selectivity"> selectivity</a> </p> <a href="https://publications.waset.org/abstracts/50900/jatropha-curcas-l-oil-selectivity-in-froth-flotation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50900.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">431</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">430</span> Attitudes of Nurses towards End-of-Life Care for Themselves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20N.%20S.%20Silva">H.

However, their wishes were mostly over ridden. Objective: To assess the attitudes of nurses towards the end-of-the-life care they would like to receive for themselves and their attitudes towards terminal illnesses. Methods: A mixed method approach was used. A closed and open-ended questionnaire was administered to 73 participants and 5 registered nurses, who have more than 10 years of experience, working in hospitals both in Sri Lanka and abroad, were interviewed. Results: 94.1% of the participants stated that they would like to die at home, spending their last hours at home surrounded by their loved ones and engaging in religious activities but 57.7% of unmarried nurse said they would agree on euthanasia if they had a terminal disease, and also 66.2% of them stated they would agree in DNR order if they happen to be admitted to the ICU, but 82.5% wanted to diagnose if they had a terminal illness or cancer but did not agree on euthanasia. Qualitative analysis confirmed the findings and revealed that despite having adequate confidence about the hospital care, nurses would choose to die at home, surrounded by their loved once and engaging in religious activities. Euthanasia was believed to be inappropriate as it is religiously incorrect and as death is a natural process. Conclusion: The perception of death among nurses depends on their religious belief. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=death" title="death">death</a>, <a href="https://publications.waset.org/abstracts/search?q=do%20not%20resuscitate" title=" do not resuscitate"> do not resuscitate</a>, <a href="https://publications.waset.org/abstracts/search?q=euthanasia" title=" euthanasia"> euthanasia</a>, <a href="https://publications.waset.org/abstracts/search?q=nurses" title=" nurses"> nurses</a> </p> <a href="https://publications.waset.org/abstracts/43888/attitudes-of-nurses-towards-end-of-life-care-for-themselves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43888.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">429</span> The Use of Cement Dust in the Glass Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magda%20Kosmal">Magda Kosmal</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20A.%20Ku%C5%9Bnierz"> Anna A.

It's considered of multiple uses, because the trunk, the fruit, and the algaroba pods are utilized for several purposes, among them, the production of wood from lumber mill, charcoal, alcohol, animal and human consumption, being hence, a culture of economic and social value. The use of waste Prosopis juliflora can be carried out for like pyrolysis and gasification processes, in order to energy production in those regions where it is grown. Thus this study aims to characterize the residue of the algaroba pods and evaluate the kinetic parameters, activation energy (Ea) and pre-exponential factor (k0), the devolatilization process through the data obtained from TG/DTG curves with different levels of heating rates. At work was used the heating rates of 5 K.min-1, 10 K.min-1, 15 K.min-1, 20 K.min-1 and 30 K.min-1, in inert nitrogen atmosphere (99.997%) under a flow of 40 ml.min-1.

The underline problem regards an NP-Hard problem concerning unrelated parallel machines, with sequence-dependent setup times. This research uses real data regarding a weaving industry located in the North of Portugal, with a capacity of 96 looms and a production, on average, of 440000 meters of fabric per month. Besides, this study includes a high level of complexity once most of the real production constraints are applied, and several real data instances are tested. Topics such as data analyses and algorithm performance are addressed and tested, to offer a solution that can generate reliable and due date results. All the approaches will be tested in the operational environment, and the KPIs monitored, to understand the solution's impact on the production, with a particular focus on the total number of weeks of late deliveries to clients. Thus, the main goal of this research is to develop a solution that allows for the production of automatically optimized production plans, aiming to the tardiness minimizing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithms" title="genetic algorithms">genetic algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20industry" title=" textile industry"> textile industry</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20scheduling" title=" job scheduling"> job scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/153173/a-genetic-algorithm-approach-to-solve-a-weaving-job-scheduling-problem-aiming-tardiness-minimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153173.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">426</span> Advantages of Vibration in the GMAW Process for Improving the Quality and Mechanical Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20A.%20C.%20Castro">C.

The welding arc is the process more widely used in industries. This is accomplished by the heat of an electric arc which melts the base metal while the molten metal droplets are transferred through the arc to the welding pool, protected from the atmosphere by a gas curtain. The GMAW (Gas metal arc welding) process is influenced by variables such as: Current, polarity, welding speed, electrode, extension, position, moving direction; type of joint, welder's ability, among others. It is remarkable that the knowledge and control of these variables are essential for obtaining satisfactory quality welds, knowing that are interconnected so that changes in one of them requiring changes in one or more of the other to produce the desired results. The optimum values are affected by the type of base metal, the electrode composition, the welding position and the quality requirements. Thus, this paper proposes a new methodology, adding the variable vibration through a mechanism developed for GMAW welding, in order to improve the mechanical and metallurgical properties which does not affect the ability of the welder and enables repeatability of the welds made. For confirmation metallographic analysis and mechanical tests were made. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vibration" title="vibration">vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=joining" title=" joining"> joining</a>, <a href="https://publications.waset.org/abstracts/search?q=weldability" title=" weldability"> weldability</a>, <a href="https://publications.waset.org/abstracts/search?q=GMAW" title=" GMAW"> GMAW</a> </p> <a href="https://publications.waset.org/abstracts/29500/advantages-of-vibration-in-the-gmaw-process-for-improving-the-quality-and-mechanical-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29500.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">424</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">425</span> Limestone Briquette Production and Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9%20C.%20Silva">André C.

Therefore, there is need for agricultural limestone implementation that provides adequate amounts of calcium and magnesium carbonates in order to correct soil acidity. During the limestone process, fine particles (with average size under 400#) are generated. These particles do not have economic value in agricultural and metallurgical sectors due their size. When limestone is used for agriculture purposes, these fine particles can be easily transported by wind generated air pollution. Therefore, briquetting, a mineral processing technique, was used to mitigate this problem resulting in an agglomerated product suitable for agriculture use. Briquetting uses compressive pressure to agglomerate fine particles. It can be aided by agglutination agents, allowing adjustments in shape, size and mechanical parameters of the mass. Briquettes can generate extra profits for mineral industry, presenting as a distinct product for agriculture, and can reduce the environmental liabilities of the fine particles storage or disposition. The produced limestone briquettes were subjected to shatter and water action resistance tests. The results show that after six minutes completely submerged in water, the briquettes where fully diluted, a highly favorable result considering its use for soil acidity correction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agglomeration" title="agglomeration">agglomeration</a>, <a href="https://publications.waset.org/abstracts/search?q=briquetting" title=" briquetting"> briquetting</a>, <a href="https://publications.waset.org/abstracts/search?q=limestone" title=" limestone"> limestone</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20acidity%20correction" title=" soil acidity correction"> soil acidity correction</a> </p> <a href="https://publications.waset.org/abstracts/50898/limestone-briquette-production-and-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50898.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">424</span> Oral Biofilm and Stomatitis Denture: Local Implications and Cardiovascular Risks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adriana%20B.%20Ribeiro">Adriana B.

This study evaluated salivary parameters, blood pressure (BP) and heart rate variability (HRV), before and after DRS treatment in edentulous patients (n=14). Collection of unstimulated and stimulated saliva, as well as blood pressure (BP) measurements and electrocardiogram recordings were performed before and after 10 days of DRS treatment. The salivary flow (mL/min) was found similar at both times while pH was smaller (more neutral) after treatment (7.3 ± 2.2 vs. 7.1 ± 0.24). Systolic BP (mmHg) showed a trend, but not a significant reduction after DRS treatment (158 ± 25.68 vs. 148 ± 16,72, p=0,062) while diastolic BP was found similar in both times (86 ± 13.93 and 84 ± 9.38). Overall HRV, measured by standard deviation of RR intervals was not affected by DRS treatment (24 ± 4 vs 18 ± 2 ms), but differences of successive RR intervals (an index of parasympathetic cardiac modulation) increased after the treatment (26 ± 4 vs 19 ± 2 ms). Moreover, another index of vagal modulation of the heart, the power of RR interval spectra at high-frequency, was also markedly higher after DRS treatment (236 ± 63 vs 135 ± 32 ms²). Such findings strongly suggest that DRS is linked to an autonomic imbalance with sympathetic overactivity, which is markedly deleterious, increasing cardiovascular risk and the incidence of diseases such as hypertension.

Data has been collected from third sector organizations operating in Portugal. Our sample includes all juridical types of organizations such as foundations, cooperative, associations or private institutions of social solidarity. The questionnaire contained sixteen close-ended questions and four open-questions. Results confirm the theoretical perspective of institutionalism. Most third sector organizations operating in Portugal implemented only traditional accounting tools like standard accounting statements, cost accounting, budgeting. Moreover, there is clear evidence that the decisions about the implementation of these tools were coercive oriented. With this study it is intended to contribute to a better understanding of the context of third sector organizations in Portugal, in particular the role that accounting plays in this sector, with a special focus on management accounting tools, and the factors that influence their use and the degree of their usefulness in the process of decision making. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=third%20sector" title="third sector">third sector</a>, <a href="https://publications.waset.org/abstracts/search?q=accounting%20tools" title=" accounting tools"> accounting tools</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20theory" title=" institutional theory"> institutional theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Portugal" title=" Portugal"> Portugal</a>, <a href="https://publications.waset.org/abstracts/search?q=descriptive%20research" title=" descriptive research"> descriptive research</a> </p> <a href="https://publications.waset.org/abstracts/47198/reasons-behind-accounting-information-tools-adopted-by-portuguese-third-sector-organizations-institutional-theory-versus-rational-choice-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47198.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">422</span> Public Behavior When Encountered with a Road Traffic Accident</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20N.%20S.%20Silva">H.

It was noticed in previous studies that policemen, three wheel drivers and also pedestrians were the first to respond to RTAs but the victim’s condition was aggravated due to unskilled attempts made by the responders while management of the victim’s wounds, moving and positioning of the victims and also mainly while transportation of the victims. Objective: To observe the practices of the urban public in Sri Lanka who are encountered with RTAs. Methods: A qualitative study was done to analyze public behavior seen on video recordings of scenes of accidents purposefully selected from social media, news websites, YouTube and Google. Results: The results showed that all individuals who tried to help during the RTA were middle aged men, who were mainly pedestrians, motorcyclists and policemen during that moment. Vast majority were very keen to actively help the victims to get to hospital as soon as possible and actively participated in providing 'aid'. But main problem was the first aid attempts were disorganized and uncoordinated. Even though all individuals knew how to control external bleeding, none of them was aware of spinal prevention techniques or management of limb injuries. Most of the transportation methods and transfer techniques used were inappropriate and more injury prone. Conclusions: The public actively engages in providing aid despite their inappropriate practices in giving first aid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=encountered" title="encountered">encountered</a>, <a href="https://publications.waset.org/abstracts/search?q=pedestrians" title=" pedestrians"> pedestrians</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20traffic%20accidents" title=" road traffic accidents"> road traffic accidents</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20public" title=" urban public"> urban public</a> </p> <a href="https://publications.waset.org/abstracts/43952/public-behavior-when-encountered-with-a-road-traffic-accident" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43952.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">286</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">421</span> The Awareness of Computer Science Students Regarding the Security of Location Based Games</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jacques%20Barnard">Jacques Barnard</a>, <a href="https://publications.waset.org/abstracts/search?q=Magda%20Huisman"> Magda Huisman</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunther%20R.%20Drevin"> Gunther R.

Starches market have been growing and improving in recent years, leading to better products attending the requirements of the mineral industry. The major source of starch used for iron ore is corn starch, which needs to be gelatinized with sodium hydroxide (NaOH) prior to use. This stage has a direct impact on industrials costs, once the lowest consumption of NaOH in gelatinization provides better control of the pH in the froth flotation and reduces the amount of electrolytes present in the pulp. In order to evaluate the gelatinization degree of different starches and flour were subjected to the addiction of NaOH and temperature variation experiments. Samples of starch (corn, cassava, HIPIX 100, HIPIX 101 and HIPIX 102 commercialized by Ingredion) and flour (cassava and potato) were tested. The starch samples were characterized through Scanning Electronic Microscopy and the amylose content were determined through spectrometry, swelling and solubility tests. The gelatinization was carried out through titration with NaOH, keeping the solution temperature constant at 40 <sup>o</sup>C. At the end of the tests, the optimal amount of NaOH consumed to gelatinize the starch or flour from different botanical sources was established and a correlation between the content of amylopectin in the starch and the starch/NaOH ratio needed for its gelatinization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=froth%20flotation" title="froth flotation">froth flotation</a>, <a href="https://publications.waset.org/abstracts/search?q=gelatinization" title=" gelatinization"> gelatinization</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20hydroxide" title=" sodium hydroxide"> sodium hydroxide</a>, <a href="https://publications.waset.org/abstracts/search?q=starches%20and%20flours" title=" starches and flours"> starches and flours</a> </p> <a href="https://publications.waset.org/abstracts/50896/optimal-consume-of-naoh-in-starches-gelatinization-for-froth-flotation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50896.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">363</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">419</span> Aeronautical Noise Management inside an Aerodrome: Analysis of Sound Exposure on Aviation Professional’s Health</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Felipe%20Guatura%20da%20Silva">Rafael Felipe Guatura da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Gomes%20da%20Silva"> José Luis Gomes da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Antonio"> Luiz Antonio</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferreira%20Perrone%20de%20Brito"> Ferreira Perrone de Brito</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Noise can cause serious damage to human health, such as hearing loss, stress, irritability, fatigue, and others. Aviation is a place where your entire process should be work out with the utmost attention and commitment of human resources, thus the need to study the effects of noise in this sector, as aeronautical noise levels are high. This study aimed to evaluate the impact of noise pollution on the performance of professionals regarding the fatigue generated by aeronautical noise and time to noise exposure. The methodology used consists of measurements of sound pressure levels at 42 points of the aerodrome. The selected points are located inside the hangars and outside the airfield hangars. All points chosen are close to the professionals' work areas, seeking to identify the sound pressure levels to which they submitted. The other part of the research used the principle on the application of a self-report questionnaire to a sample of 207 people working inside the aerodrome. The 207 professionals surveyed consist of aircraft mechanics, pilots, maintenance managers, and administrative professionals. The questionnaire was intended to evaluate the knowledge that professionals have about health risks caused by sound exposure as well as to identify diseases that professionals have, and that may be associated with exposure to high levels of sound pressure. Preliminary results identify points with sound pressure levels of up to 91.7 dB, thus highlighting the need for the use of personal protective equipment that reduces noise exposure. It was also identified a large number of professionals who are bothered by the sound exposure and approximately 25% of professionals interviewed reported having a hearing disorder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aeronautical%20noise" title="aeronautical noise">aeronautical noise</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20and%20health" title=" noise and health"> noise and health</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20management" title=" noise management"> noise management</a> </p> <a href="https://publications.waset.org/abstracts/113625/aeronautical-noise-management-inside-an-aerodrome-analysis-of-sound-exposure-on-aviation-professionals-health" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113625.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">147</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">418</span> Smart Safari: Safari Guidance Mobile Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20P.%20Lawrence">D.

In Sri Lanka, 'Yala' is the second-largest national park, which is a better place to go for a safari. Many number of local and foreign travelers are coming to go for a safari in 'Yala'. But 'Yala' does not have a mobile application that is made to facilitate the traveler with some important features that the traveler wants to achieve in the safari experience. To overcome these difficulties, the proposed mobile application by adding those identified features to make travelers, guiders, and administration's works easier. The proposed safari traveling guidance mobile application is called 'SMART SAFARI' for the 'Yala' National Park in Sri Lanka. There are four facilities in this mobile application that provide for travelers as well as the guiders. As the first facility, the guider and traveler can view the created map of the park, and the guider can add temporary locations of animals and special locations on the map. This is a Geographic Information System (GIS) to capture, analyze, and display geographical data. And as the second facility is to generate optimal paths according to the travelers' requirements through the park by using machine learning techniques. In the third part, the traveler can get information about animals using an animal identification system by capturing the animal. As in the other facility, the traveler will be facilitated to add reviews and a rate and view those comments under categorized sections and pre-defined score range. With those facilities, this user-friendly mobile application provides the user to get a better experience in safari traveling, and it will probably help to develop tourism culture in Sri Lanka. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20identification%20system" title="animal identification system">animal identification system</a>, <a href="https://publications.waset.org/abstracts/search?q=geographic%20information%20system" title=" geographic information system"> geographic information system</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning%20techniques" title=" machine learning techniques"> machine learning techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=pre%20defined%20score%20range" title=" pre defined score range"> pre defined score range</a> </p> <a href="https://publications.waset.org/abstracts/132289/smart-safari-safari-guidance-mobile-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132289.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">133</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">417</span> Extending the Theory of Planned Behaviour to Predict Intention to Commute by Bicycle: Case Study of Mexico City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magda%20Cepeda">Magda Cepeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Frances%20Hodgson"> Frances Hodgson</a>, <a href="https://publications.waset.org/abstracts/search?q=Ann%20Jopson"> Ann Jopson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are different barriers people face when choosing to cycle for commuting purposes. This study examined the role of psycho-social factors predicting the intention to cycle to commute in Mexico City. An extended version of the theory of planned behaviour was developed and utilized with a simple random sample of 401 road users. We applied exploratory and confirmatory factor analysis and after identifying five factors, a structural equation model was estimated to find the relationships among the variables. The results indicated that cycling attributes, attitudes to cycling, social comparison and social image and prestige were the most important factors influencing intention to cycle. Although the results from this study are specific to Mexico City, they indicate areas of interest to transportation planners in other regions especially in those cities where intention to cycle its linked to its perceived image and there is political ambition to instigate positive cycling cultures. Moreover, this study contributes to the current literature developing applications of the Theory of Planned Behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cycling" title="cycling">cycling</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20variable%20model" title=" latent variable model"> latent variable model</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a>, <a href="https://publications.waset.org/abstracts/search?q=theory%20of%20planned%20behaviour" title=" theory of planned behaviour"> theory of planned behaviour</a> </p> <a href="https://publications.waset.org/abstracts/59532/extending-the-theory-of-planned-behaviour-to-predict-intention-to-commute-by-bicycle-case-study-of-mexico-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59532.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">353</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">416</span> Nano Sol Based Solar Responsive Smart Window for Aircraft</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20A.%20D.%20D.%20Kuruppu">K.

Further, this surface has the potential of harvesting energy from Solar. The transparent inorganic nano sol solution was prepared. The obtained sol solution was characterized using X-ray diffraction, Particle size analyzer and FT-IR. The existing nano material which shows the similar characteristics was also used to compare the efficiencies with the newly prepared nano sol. Nano sol solution was coated on cleaned four aircraft window pieces separately using a spin coater machine. The existing nano material was dissolved and prepared a solution having the similar concentration as nano sol solution. Pre-cleaned four aircraft window pieces were coated with this solution and the rest cleaned four aircraft window pieces were considered as control samples. The control samples were uncoated from anything. All the window pieces were allowed to dry at room temperature. All the twelve aircraft window pieces were uniform in all the factors other than the type of coating. The surface morphologies of the samples were analyzed using SEM. The photocatalytic degradation of VOC was determined after incorporating gas of Toluene to each sample followed by the analysis done by UV-VIS spectroscopy. The self- cleaning capabilities were analyzed after adding of several types of stains on the window pieces. The self-cleaning property of each sample was analyzed using UV-VIS spectroscopy. The highest photocatalytic degradation of Volatile Organic compound and the highest photocatalytic degradation of stains were obtained for the samples which were coated by the nano sol solution. Therefore, the experimental results clearly show that there is a potential of using this nano sol in aircraft window pieces which favors the self-cleaning property as well as efficient photocatalytic degradation of VOC gases. This will ensure safer environment inside aircraft cabins. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aircraft"
