The simulations showed that the circuit presented ensures immunity corresponding with test level IV of the IEC 61000-4-5:2014 international standard. The developed circuit can be modified to meet the requirements of any other equipment to be protected. Similarly, the parameters of the combination wave generator can be changed to provide different surge amplitudes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combination%20wave%20generator" title="combination wave generator">combination wave generator</a>, <a href="https://publications.waset.org/abstracts/search?q=IEC%2061000-4-5" title=" IEC 61000-4-5"> IEC 61000-4-5</a>, <a href="https://publications.waset.org/abstracts/search?q=Pspice%20simulation" title=" Pspice simulation"> Pspice simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=surge%20protection" title=" surge protection"> surge protection</a> </p> <a href="https://publications.waset.org/abstracts/57544/simulation-of-surge-protection-for-a-direct-current-circuit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57544.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">327</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">663</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">662</span> Model for Assessment of Quality Airport Services</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20da%20Silva%20Torres">Cristina da Silva Torres</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Duarte%20Ribeiro"> José Luis Duarte Ribeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Auxiliadora%20Cannarozzo%20Tinoco"> Maria Auxiliadora Cannarozzo Tinoco </a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a result of the rapid growth of the Brazilian Air Transport, many airports are at the limit of their capacities and have a reduction in the quality of services provided. Thus, there is a need of models for assessing the quality of airport services. Because of this, the main objective of this work is to propose a model for the evaluation of quality attributes in airport services. To this end, we used the method composed by literature review and interview. Structured a working method composed by 5 steps, which resulted in a model to evaluate the quality of airport services, consisting of 8 dimensions and 45 attributes. Was used as base for model definition the process mapping of boarding and landing processes of passengers and luggage. As a contribution of this work is the integration of management process with structuring models to assess the quality of services in airport environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20airport%20services" title="quality airport services">quality airport services</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20for%20identification%20of%20attributes%20quality" title=" model for identification of attributes quality"> model for identification of attributes quality</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20transport" title=" air transport"> air transport</a>, <a href="https://publications.waset.org/abstracts/search?q=passenger" title=" passenger"> passenger</a> </p> <a href="https://publications.waset.org/abstracts/24893/model-for-assessment-of-quality-airport-services" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24893.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">535</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">661</span> RF Propagation Analysis in Outdoor Environments Using RSSI Measurements Applied in ZigBee Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <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=Jos%C3%A9%20Anderson%20Rodrigues%20de%20Souza"> José Anderson Rodrigues de Souza</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> Propagation in radio frequency is a constant concern in the application of Wireless Sensor Networks (WSN), the behavior of an environment determines how good the quality of signal reception.

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">658</span> The Public Law Studies: Relationship Between Accountability, Environmental Education and Smart Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aline%20Alves%20Bandeira">Aline Alves Bandeira</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADs%20Pedro%20Lima"> Luís Pedro Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Cec%C3%ADlia%20de%20Paula%20Silva"> Maria Cecília de Paula Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Henrique%20de%20Viveiros%20Tavares"> Paulo Henrique de Viveiros Tavares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the study of public policies regarding management efficiency is essential. 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.

Current knowledge regarding the health benefits and antioxidant properties of certain foods such as fruits and vegetables has gained the interest of both the general public and scientific community. Peach (Prunus persica (L.) Batsch) is one of the most consumed fruits worldwide, with low sugar contents and a broad range of nutrients essential to the normal functioning of the body. Six different peach cultivars from the Fundão region in Portugal were evaluated regarding their phenolic composition by LC-DAD and biological activity. The prepared extracts’ capacity to scavenge free-radicals was tested through the stable free radical DPPH• and nitric oxide (•NO). Additionally, antidiabetic potential and protective effects against peroxyl radical (ROO•) induced damage to erythrocytes were also tested. LC-DAD analysis allowed the identification of 17 phenolic compounds, among which 5-O-caffeoylquinic acids and 3-O-caffeoylquinic acids are pointed out as the most abundant. Regarding the antioxidant activity, all cultivars displayed concentration-dependent free-radical scavenging activity against both nitrogen species and DPPH•. In respect to α-glucosidase inhibitory activity, Royal Magister and Royal Glory presented the highest inhibitory activity (IC50 = 11.7 ± 1.4 and 17.1 ± 1.7 μg/mL, respectively), nevertheless all six cultivars presented higher activity than the control acarbose. As for the protective effect of Royal Lu extract on the oxidative damage induced in erythrocytes by ROO•, the results were quite promising showing inhibition IC50 values of 110.0 ± 4.5 μg/mL and 83.8 ± 6.5 μg/mL for hemolysis and hemoglobin oxidation, respectively. The demonstrated activity is of course associated to the peaches’ phenolic profile, rich in phenolic acids and flavonoids with high hydrogen donating capacity. These compounds have great industrial interest for the manufacturing of natural products. The following step would naturally be the extraction and isolation from the plant tissues and large-scale production through biotechnology techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidants" title="antioxidants">antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=peach" title=" peach"> peach</a> </p> <a href="https://publications.waset.org/abstracts/70855/peach-as-a-potential-functional-food-biological-activity-and-important-phenolic-compound-source" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70855.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">294</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">654</span> Sustainable Solutions for Urban Problems: Industrial Container Housing for Endangered Communities in Maranhao, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helida%20Thays%20Gomes%20Soares">Helida Thays Gomes Soares</a>, <a href="https://publications.waset.org/abstracts/search?q=Conceicao%20De%20Maria%20Pinheiro%20Correia"> Conceicao De Maria Pinheiro Correia</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabiano%20Maciel%20Soares"> Fabiano Maciel Soares</a>, <a href="https://publications.waset.org/abstracts/search?q=Kleymer%20Silva"> Kleymer Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is great discussion around populational increase in urban areas of the global south, and, consequently, the growth of inappropriate housing and the different ways humans have found to solve housing problems around the world. Sao Luís, the capital of the state of Maranhao is a good example. The 1.6 million inhabitant metropole is a colonial tropical city that shelters 22% of the population of Maranhão, brazilian state that still carries the scars of slavery in past centuries. In 2016, Brazilian Institute of Geography and Statistic found that 20% of Maranhão’s inhabitants were living in houses with external walls made of non-durable materials, like recycled wood, cardboard or soil. Out of this problematic, this study aims to propose interventions not only in the physical structure of irregular housing, but also to serve as a guide to intervene in the way eco-friendly, communitarian housing is seen by extreme poor zones inside metropolitan regions around big cities in the global south. The adaptation and reuse of industrial containers from the Harbor of Itaqui for housing is also an aim of the project. The great volume of discarded industrial containers may be an opportunity to solve housing deficit in the city. That way, through field research in São Luís’ neighborhoods mostly occupied by inappropriate housing, the study intends to raise ethnographical and physical values that help to shape new uses of industrial containers and recycled building materials, bringing the community into the process of shaping new-housing for local housing programs, changing the mindset of a concrete/brick model of building. The study used a general feasibility analysis of local engineers regarding strength of the locally used container for construction purposes, and also researched in-loco the current impressions of risky areas inhabitants of housing, traditional housing and the role they played as city shapers, evaluating their perceptions of what means to live and how their houses represent their personality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=container%20housing" title="container housing">container housing</a>, <a href="https://publications.waset.org/abstracts/search?q=civil%20construction" title=" civil construction"> civil construction</a>, <a href="https://publications.waset.org/abstracts/search?q=housing%20deficit" title=" housing deficit"> housing deficit</a>, <a href="https://publications.waset.org/abstracts/search?q=participatory%20design" title=" participatory design"> participatory design</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/105723/sustainable-solutions-for-urban-problems-industrial-container-housing-for-endangered-communities-in-maranhao-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105723.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">653</span> Saco Sweet Cherry from Fundão Region, Portugal: Chemical Profile and Health-Promoting Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADs%20R.%20Silva">Luís R.

Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prunus avium Linnaeus, more known as sweet cherry, is one of the most appreciated fruit worldwide. Most of these quantities are produced in Fundão region, being Saco the cultivar most produced. Saco is very rich in bioactive compounds, especially phenolics, and presents great antioxidant capacity. The purpose of the present study was to investigate the chemical profile and biological potential, concerning antioxidant, anti-diabetic activity and protective effects towards erythrocytes by Saco sweet cherry collected from Fundão region (Portugal). The hydroethanolic extracts were prepared and passed through a C18 solid-phase extraction column. The phenolic profile analyzed by LC-DAD method allowed to the identification of 22 phenolic compounds, being 16 non-phenolics and 6 anthocyanins. In respect to non-coloured phenolics, 3-O-caffeoylquinic and ρ-coumaroylquinic acids were the main ones. Concerning to anthocyanins, cyanidin-3-O-rutinoside was found in higher amounts. Relatively to biological potential, Saco showed great antioxidant potential, through DPPH and NO radical assays, with IC50 =16.24 ± 0.46 µg/mL and IC50 = 176.69 ± 3.35 µg/mL for DPPH and NO, respectively. These results were similar to those obtained for ascorbic acid control (IC50 = 16.92 ± 0.69 and IC50 = 162.66 ± 1.31 μg/mL for DPPH and NO, respectively). In respect to antidiabetic potential, Saco revealed capacity to inhibit α-glucosidase in a dose-dependent manner (IC50 = 10.79 ± 0.40 µg/mL), being much active than positive control acarbose (IC50 = 306.66 ± 0.84 μg/mL). Additionally, Saco extracts revealed protective effects against ROO•-mediated toxicity generated by AAPH in human blood erythrocytes, inhibiting hemoglobin oxidation (IC50 = 38.57 ± 0.96 μg/mL) and hemolysis (IC50 = 73.03 ± 1.48 μg/mL), in a concentration-dependent manner. However, Saco extracts were less effective than quercetin control (IC50 = 3.10 μg/mL and IC50 = 0.7 μg/mL for inhibition of hemoglobin oxidation and hemolysis, respectively). The results obtained showed that Saco is an excellent source of phenolic compounds. These ones are natural antioxidant substances, which easily capture reactive species. This work presents new insights regarding sweet cherry antioxidant properties which may be useful for the future development of new therapeutic strategies for preventing or attenuating oxidative-related disorders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20capacity" title="antioxidant capacity">antioxidant capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20benefits" title=" health benefits"> health benefits</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=saco" title=" saco"> saco</a> </p> <a href="https://publications.waset.org/abstracts/70856/saco-sweet-cherry-from-fundao-region-portugal-chemical-profile-and-health-promoting-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70856.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">316</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">652</span> Effect of Ultrasound on the Hydrolysis of Soy Oil Catalyzed by 1,3-Specific Lipase Abstract </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Abd%20Awadallak">Jamal Abd Awadallak</a>, <a href="https://publications.waset.org/abstracts/search?q=Thiago%20Olinek%20Reinehr"> Thiago Olinek Reinehr</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Raizer"> Eduardo Raizer</a>, <a href="https://publications.waset.org/abstracts/search?q=Deise%20Molinari"> Deise Molinari</a>, <a href="https://publications.waset.org/abstracts/search?q=Edson%20Antonio"> Edson Antonio</a>, <a href="https://publications.waset.org/abstracts/search?q=Camila%20da%20Silva%20da%20Silva"> Camila da Silva da Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The hydrolysis of soy oil catalyzed by 1,3-specific enzyme (Lecitase Ultra) in a well-stirred bioreactor was studied.

A kinetic study was conducted to determine the reaction order and the activation energy. A statistical study was conducted to determine optimal reaction conditions. Initially, the crude oil was refined salmon physically and chemically. The crude oil was hydrolyzed and unsaturated free fatty acids were separated by urea complexation method. An experimental project to verify the parameters (temperature, glycerin and catalyst) with the greatest impact on the reaction was developed. In experiments aliquots were taken at predetermined times to measure the amount of free fatty acids. Pareto, surface, contour and hub graphs were used to determine the factors that maximized the reaction. According to the graphs the best reaction conditions were: temperature 80 ° C, the proportion glycerine/oil 5: 1 and 1% of catalyst. The kinetic data showed that the system was compatible with a second-order reaction. After analyzing the rate constant versus temperature charts a value of 85.31 kJ/mol was obtained for the reaction activation energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=esterification" title="esterification">esterification</a>, <a href="https://publications.waset.org/abstracts/search?q=kinect" title=" kinect"> kinect</a>, <a href="https://publications.waset.org/abstracts/search?q=oil" title=" oil"> oil</a>, <a href="https://publications.waset.org/abstracts/search?q=salmon" title=" salmon"> salmon</a> </p> <a href="https://publications.waset.org/abstracts/21393/kinetic-study-of-the-esterification-of-unsaturated-fatty-acids-from-salmon-oil-salmosalar-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21393.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">521</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">648</span> Human Resources Management Practices in Hospitality Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dora%20Martins">Dora Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Susana%20Silva"> Susana Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A2ndida%20Silva"> Cândida Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human Resources Management (HRM) has been recognized by academics and practitioners as an important element in organizations. 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. According to these results, the paper discusses the major theoretical and practical implications.

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">170</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">646</span> Food Safety in Wine: Removal of Ochratoxin a in Contaminated White Wine Using Commercial Fining Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ant%C3%B2nio%20In%C3%AAs">Antònio Inês</a>, <a href="https://publications.waset.org/abstracts/search?q=Davide%20Silva"> Davide Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Filipa%20Carvalho"> Filipa Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADs%20Filipe-Riberiro"> Luís Filipe-Riberiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20M.%20Nunes"> Fernando M.

Mycotoxins are toxic secondary metabolites produced by certain molds, being ochratoxin A (OTA) one of the most relevant. Wines can also be contaminated with these toxicants. Several authors have demonstrated the presence of mycotoxins in wine, especially ochratoxin A. Its chemical structure is a dihydro-isocoumarin connected at the 7-carboxy group to a molecule of L-β-phenylalanine via an amide bond. As these toxicants can never be completely removed from the food chain, many countries have defined levels in food in order to attend health concerns. OTA contamination of wines might be a risk to consumer health, thus requiring treatments to achieve acceptable standards for human consumption. The maximum acceptable level of OTA in wines is 2.0 μg/kg according to the Commission regulation No. 1881/2006. Therefore, the aim of this work was to reduce OTA to safer levels using different fining agents, as well as their impact on white wine physicochemical characteristics. To evaluate their efficiency, 11 commercial fining agents (mineral, synthetic, animal and vegetable proteins) were used to get new approaches on OTA removal from white wine. Trials (including a control without addition of a fining agent) were performed in white wine artificially supplemented with OTA (10 µg/L). OTA analyses were performed after wine fining. Wine was centrifuged at 4000 rpm for 10 min and 1 mL of the supernatant was collected and added of an equal volume of acetonitrile/methanol/acetic acid (78:20:2 v/v/v). Also, the solid fractions obtained after fining, were centrifuged (4000 rpm, 15 min), the resulting supernatant discarded, and the pellet extracted with 1 mL of the above solution and 1 mL of H2O. OTA analysis was performed by HPLC with fluorescence detection. The most effective fining agent in removing OTA (80%) from white wine was a commercial formulation that contains gelatin, bentonite and activated carbon. Removals between 10-30% were obtained with potassium caseinate, yeast cell walls and pea protein. With bentonites, carboxymethylcellulose, polyvinylpolypyrrolidone and chitosan no considerable OTA removal was verified. Following, the effectiveness of seven commercial activated carbons was also evaluated and compared with the commercial formulation that contains gelatin, bentonite and activated carbon. The different activated carbons were applied at the concentration recommended by the manufacturer in order to evaluate their efficiency in reducing OTA levels. Trial and OTA analysis were performed as explained previously. The results showed that in white wine all activated carbons except one reduced 100% of OTA. The commercial formulation that contains gelatin, bentonite and activated carbon reduced only 73% of OTA concentration. These results may provide useful information for winemakers, namely for the selection of the most appropriate oenological product for OTA removal, reducing wine toxicity and simultaneously enhancing food safety and wine quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wine" title="wine">wine</a>, <a href="https://publications.waset.org/abstracts/search?q=ota%20removal" title=" ota removal"> ota removal</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20safety" title=" food safety"> food safety</a>, <a href="https://publications.waset.org/abstracts/search?q=fining" title=" fining"> fining</a> </p> <a href="https://publications.waset.org/abstracts/31580/food-safety-in-wine-removal-of-ochratoxin-a-in-contaminated-white-wine-using-commercial-fining-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31580.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">538</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">645</span> Observations on the Eastern Red Sea Elasmobranchs: Data on Their Distribution and Ecology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frappi%20Sofia">Frappi Sofia</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Pilcher"> Nicolas Pilcher</a>, <a href="https://publications.waset.org/abstracts/search?q=Sander%20DenHaring"> Sander DenHaring</a>, <a href="https://publications.waset.org/abstracts/search?q=Royale%20Hardenstine"> Royale Hardenstine</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Silva"> Luis Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Collin%20Williams"> Collin Williams</a>, <a href="https://publications.waset.org/abstracts/search?q=Mattie%20Rodrigue"> Mattie Rodrigue</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincent%20Pieriborne"> Vincent Pieriborne</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Qurban"> Mohammed Qurban</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20M.%20Duarte"> Carlos M.

The decline of these species can trigger a cascade effect, which may eventually lead to detrimental impacts on local ecosystems. The Elasmobranch in the Red Sea is facing one of the highest risks of extinction, mainly due to unregulated fisheries activities. Thus, it is of paramount importance to assess their current distribution and unveil their environmental preferences in order to improve conservation measures. Important data have been collected throughout the whole red Sea during the Red Sea Decade Expedition (RSDE) to achieve this goal. Elasmobranch sightings were gathered through the use of submarines, remotely operated underwater vehicles (ROV), scuba diving operations, and helicopter surveys. Over a period of 5 months, we collected 891 sightings, 52 with submarines, 138 with the ROV, 67 with the scuba diving teams, and 634 from helicopters. In total, we observed 657 and 234 individuals from the superorder Batoidea and Selachimorpha, respectively. The most common shark encountered was Iago omanensis, a deep-water shark of the order Carcharhiniformes. To each sighting, data on temperature, salinity density, and dissolved oxygen were integrated to reveal favorable conditions for each species. Additionally, an extensive literature review on elasmobranch research in the Eastern Red Sea has been carried out in order to obtain more data on local populations and to be able to highlight patterns of their distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distribution" title="distribution">distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=elasmobranchs" title=" elasmobranchs"> elasmobranchs</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat" title=" habitat"> habitat</a>, <a href="https://publications.waset.org/abstracts/search?q=rays" title=" rays"> rays</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20sea" title=" red sea"> red sea</a>, <a href="https://publications.waset.org/abstracts/search?q=sharks" title=" sharks"> sharks</a> </p> <a href="https://publications.waset.org/abstracts/162007/observations-on-the-eastern-red-sea-elasmobranchs-data-on-their-distribution-and-ecology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162007.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">85</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">644</span> Vieira Da Silva'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">643</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">172</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">642</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">153</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">641</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. The main source of these compounds are fruits and derivates. This study had the objective to study the bioacessibility of phenolic compounds from grape pomace and juçara dried extracts. For this purpose both characterized extracts were submitted to a simulated human digestion and the total phenolic content, total anthocyanins and antioxidant scavenging capacity was determinate in digestive fractions (oral, gastric, intestinal and colonic). 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. The lyophilized process had a beneficial impact in the final accessibility of the phenolic compounds being a more promising technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioacessibility" title="bioacessibility">bioacessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=grape" title=" grape"> grape</a>, <a href="https://publications.waset.org/abstracts/search?q=ju%C3%A7ara" title=" juçara"> juçara</a> </p> <a href="https://publications.waset.org/abstracts/95136/in-vitro-bioacessibility-of-phenolic-compounds-from-fruit-spray-dried-and-lyophilized-powder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95136.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">213</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">640</span> Optimization of Quercus cerris Bark Liquefaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADsa%20P.%20Cruz-Lopes">Luísa P.

In this particular study the bark of <em>Quercus cerris</em> (Turkish oak) is used due to its appreciable amount of cork tissue, although of inferior quality when compared to the cork provided by other Quercus trees. This study aims to optimize alkaline catalysis liquefaction conditions, regarding several parameters. To better comprehend the possible chemical characteristics of the bark of <em>Quercus cerris</em>, a complete chemical analysis was performed. The liquefaction process was performed in a double-jacket reactor heated with oil, using glycerol and a mixture of glycerol/ethylene glycol as solvents, potassium hydroxide as a catalyst, and varying the temperature, liquefaction time and granulometry. Due to low liquefaction efficiency resulting from the first experimental procedures a study was made regarding different washing techniques after the filtration process using methanol and methanol/water. The chemical analysis stated that the bark of <em>Quercus cerris</em> is mostly composed by suberin (<em>ca.</em> 30%) and lignin (<em>ca.</em> 24%) as well as insolvent hemicelluloses in hot water (<em>ca.</em> 23%). On the liquefaction stage, the results that led to higher yields were: using a mixture of methanol/ethylene glycol as reagents and a time and temperature of 120 minutes and 200 ºC, respectively. It is concluded that using a granulometry of <80 mesh leads to better results, even if this parameter barely influences the liquefaction efficiency. Regarding the filtration stage, washing the residue with methanol and then distilled water leads to a considerable increase on final liquefaction percentages, which proves that this procedure is effective at liquefying suberin content and lignocellulose fraction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liquefaction" title="liquefaction">liquefaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Quercus%20cerris" title=" Quercus cerris"> Quercus cerris</a>, <a href="https://publications.waset.org/abstracts/search?q=polyalcohol%20liquefaction" title=" polyalcohol liquefaction"> polyalcohol liquefaction</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/52423/optimization-of-quercus-cerris-bark-liquefaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52423.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">333</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">639</span> Jatropha curcas L.

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’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’s flotation) followed by direct flotation circuit (rougher, cleaner and scavenger circuit). Since the 70’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">638</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">637</span> Evaluate the Kinetic Parameters and Characterize for Waste Prosopis juliflora Pods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jean%20C.%20G.%20Silva">Jean C.

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
