Vegetable oils present some properties that may favor their use as biolubricants; however, there are others, such as resistance to oxidation and pour point, which affect possible commercial applications. In this study, the physicochemical properties of biolubricants synthesized from different vegetable oils were evaluated and compared with petroleum-based lubricant and pure vegetable oil. Chemical modifications applied to the original vegetable oil improved their oxidative stability and pour point significantly. The addition of commercial antioxidants to the bio-based lubricants was evaluated, yielding values of oxidative stability close to those of mineral basestock oil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biolubricant" title="biolubricant">biolubricant</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetable%20oil" title=" vegetable oil"> vegetable oil</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stability" title=" oxidative stability"> oxidative stability</a>, <a href="https://publications.waset.org/abstracts/search?q=pour%20point" title=" pour point"> pour point</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidants" title=" antioxidants"> antioxidants</a> </p> <a href="https://publications.waset.org/abstracts/56166/studies-on-the-physicochemical-properties-of-biolubricants-obtained-from-vegetable-oils-and-their-oxidative-stability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56166.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">312</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Technology Enhanced Learning Using Virtual and Augmented Realities: An Applied Method to Improve the Animation Teaching Delivery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Marar">Rosana Marar</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Jaser"> Edward Jaser</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a software solution to enhance the content and presentation of graphic design and animation related textbooks.

With this purpose in mind, a quantitative survey was performed for a non- graduate probabilistic sample of management business students of a private university in Rio de Janeiro. The results of the survey showed there is no significant association between satisfaction at work and alignment with the individual’s career anchor. The most frequent career anchor found for both genders was lifestyle, showing a trend towards finding a career that allows some balance between professional and personal life. The study also showed that self-employed individuals are more satisfied with their work than the individuals employed by a company are, and men are more satisfied at work than women are, Individuals aligned and not satisfied tend to be the ones who have fewer years of work experience and individuals not aligned and satisfied tend to be older. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=careers" title="careers">careers</a>, <a href="https://publications.waset.org/abstracts/search?q=career%20anchors" title=" career anchors"> career anchors</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20satisfaction" title=" job satisfaction"> job satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Schein%C2%B4s%20career%20anchor%20model" title=" Schein´s career anchor model"> Schein´s career anchor model</a> </p> <a href="https://publications.waset.org/abstracts/35499/job-satisfaction-and-career-choices-a-study-using-scheins-career-anchor-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35499.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">12</span> Pilot Study of the Psychometric Properties of the Test of Predisposition towards the Bullying</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Choy">Rosana Choy</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabiola%20Henostroza"> Fabiola Henostroza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Actual theory suggests social-ecological factors as the main framework of bullying. Most previous research in this phenomenon is focused on the identification of bullying attitudes and conducts in puberty and adolescence periods. For this reason, this study is considered as a contribution to the existing knowledge in measuring matters, because of its non-traditional way of evaluation (graphic items), and because of its approach to a distinctive age group, children from 7 to 9 years-old, not regularly examined in current studies in this field. The research used a transversal descriptive investigation design for the development of a graphic test for bullying predisposition. The process began with the operationalization of the variable bullying predisposition, the structuring of the factors and variable indicators of a pilot instrument, evaluation by experts of the items representation, and finally it continued with the test application to children of two types of regular school population in Lima-Peru: private and public schools. The reliability level was 0.85 and the validity of the test corroborated the three-factor structure proposed by the researchers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bullying" title="bullying">bullying</a>, <a href="https://publications.waset.org/abstracts/search?q=graphic%20test" title=" graphic test"> graphic test</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=validity" title=" validity"> validity</a> </p> <a href="https://publications.waset.org/abstracts/68067/pilot-study-of-the-psychometric-properties-of-the-test-of-predisposition-towards-the-bullying" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68067.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">266</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">11</span> Forklift Allocation in Warehouse Operations with Restricted Halls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Becerra%20Fern%C3%A1ndez">Mauricio Becerra Fernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Rosana%20Romero%20Quiroga"> Olga Rosana Romero Quiroga</a>, <a href="https://publications.waset.org/abstracts/search?q=Elsa%20Cristina%20Gonz%C3%A1lez%20La%20Rotta"> Elsa Cristina González La Rotta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The logistics facilities design and construction is one of the strategic decisions that critically affects the performance of the company, from the economic perspective and relationship with customers. The case study company is the Colombian logistic sector leader, with over 60 years of experience, with sales of about one hundred twenty million dollars at the end of 2014. The preliminary design for the warehouse layout and operation includes a customer that provides approximately 17% of the profits of the company, considering the possibility of moving two forklifts in the warehouse halls. Some changes were not consider in previous stages of design, operations required forklift with different characteristics, whose size, do not allow the circulation of more than a forklift at a time. Therefore, it is necessary to assess the impact of this restriction on the warehouse operation, so decision makers implement actions to achieve efficient operation. The problem is addressed by recognizing logistics processes, which develop in a warehouse, collection of processes information behavior, the simulation of the current situation using ProModel software, model validation, making adjustments required, experiments design, conclusions and recommendations for the company. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design" title="design">design</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20events%20simulation" title=" discrete events simulation"> discrete events simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=forklift%20allocation" title=" forklift allocation"> forklift allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics%20facilities" title=" logistics facilities"> logistics facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=warehouse" title=" warehouse"> warehouse</a> </p> <a href="https://publications.waset.org/abstracts/41694/forklift-allocation-in-warehouse-operations-with-restricted-halls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41694.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">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Body Image Dissatifaction with and Personal Behavioral Control in Obese Patients Who are Attending to Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariela%20Gonzalez">Mariela Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Zoraide%20Lugli"> Zoraide Lugli</a>, <a href="https://publications.waset.org/abstracts/search?q=Eleonora%20Vivas"> Eleonora Vivas</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Guzm%C3%A1n"> Rosana Guzmán</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective was to determine the predictive capacity of self-efficacy perceived for weight control, locus of weight control and skills of weight self-management in the dissatisfaction of the body image in obese people who attend treatment. Sectional study conducted in the city of Maracay, Venezuela, with 243 obese who attend to treatment, 173 of the feminine gender and 70 of the male, with ages ranging between 18 and 57 years old. The sample body mass index ranged between 29.39 and 44.14. The following instruments were used: The Body Shape Questionnaire (BSQ), the inventory of body weight self-regulation, The Inventory of self-efficacy in the regulation of body weight and the Inventory of the Locus of weight control. Calculating the descriptive statistics and of central tendency, coefficients of correlation and multiple regression; it was found that a low ‘perceived Self-efficacy in the weight control’ and a high ‘Locus of external control’, predict the dissatisfaction with body image in obese who attend treatment. The findings are a first approximation to give an account of the importance of the personal control variables in the study of the psychological grief on the overweight individual. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dissatisfaction%20with%20body%20image" title="dissatisfaction with body image">dissatisfaction with body image</a>, <a href="https://publications.waset.org/abstracts/search?q=obese%20people" title=" obese people"> obese people</a>, <a href="https://publications.waset.org/abstracts/search?q=personal%20control" title=" personal control"> personal control</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20variables" title=" psychological variables"> psychological variables</a> </p> <a href="https://publications.waset.org/abstracts/41166/body-image-dissatifaction-with-and-personal-behavioral-control-in-obese-patients-who-are-attending-to-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41166.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">432</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">9</span> Techno-Economic Study on the Potential of Dimethyl Ether (DME) as a Substitute for LPG</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Widya%20Anggraini%20Pamungkas">Widya Anggraini Pamungkas</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Budi%20Setyawati"> Rosana Budi Setyawati</a>, <a href="https://publications.waset.org/abstracts/search?q=Awaludin%20Fitroh%20Rifai"> Awaludin Fitroh Rifai</a>, <a href="https://publications.waset.org/abstracts/search?q=Candra%20Pangesti%20Setiawan"> Candra Pangesti Setiawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Anatta%20Wahyu%20Budiiman"> Anatta Wahyu Budiiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Inayati"> Inayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Joko%20Waluyo"> Joko Waluyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunu%20Herwi%20Pranolo"> Sunu Herwi Pranolo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increase in LPG consumption in Indonesia is not balanced with the amount of supply. The high demand for LPG due to the success of the government's kerosene-to-LPG conversion program and the Covid-19 pandemic in 2020 led to an increase in LPG consumption in the household sector and caused Indonesia's trade balance to experience a deficit. The high consumption of LPG encourages the need for alternative fuels as a substitute or which aims to substitute LPG; one of the materials that can be used is Dimethyl Ether (DME). Dimethyl ether (DME) is an organic compound with the chemical formula CH 3. OCH 3 has a high cetane number and has characteristics similar to LPG. DME can be produced from various sources, such as coal, biomass and natural gas. Based on the economic analysis conducted at 10% IRR, coal has the largest NPV of Rp. 20,034,837,497,241 with a payback period of 3.86 years, then biomass with an NPV of Rp. 10,401,526,072,850 and a payback period of 5.16. the latter is natural gas with an NPV of IDR 7,401,272,559,191 and a payback period of 6.17 years. Of the three sources of raw materials used, if the sensitivity is calculated using the selling price of DME equal to the selling price of LPG, it will get an NPV value that is greater than the NPV value when using the current DME price. The advantages of coal as a raw material for DME are not only because it is profitable, namely: low price and abundant resources, but has high greenhouse gas emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LPG" title="LPG">LPG</a>, <a href="https://publications.waset.org/abstracts/search?q=DME" title=" DME"> DME</a>, <a href="https://publications.waset.org/abstracts/search?q=coal" title=" coal"> coal</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20gas" title=" natural gas"> natural gas</a> </p> <a href="https://publications.waset.org/abstracts/161115/techno-economic-study-on-the-potential-of-dimethyl-ether-dme-as-a-substitute-for-lpg" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161115.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Gethuk Marillo: The New Product Development of Anti-Cancer Snacks Utilizing Xanthones and Anthocyanin in Mangosteen Pericarp and Tamarillo Fruit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Desi%20Meriyanti">Desi Meriyanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Delina%20Puspa%20Rosana%20Firdaus"> Delina Puspa Rosana Firdaus</a>, <a href="https://publications.waset.org/abstracts/search?q=Ristia%20Rinati"> Ristia Rinati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the presence of free radicals become a big concern due to its negative impact to the body, which can triggers the formation of degenerative diseases such as cancer, heart disease cardiovascular, diabetic mellitus and others. Free radical oxidation can be prevented by the presence of antioxidants. Naturally, the human body produces its own antioxidants. Because of the free radicals exposure are so intense, especially from the environment, it is necessary to supply antioxidants needed from outside, through the consumption of functional foods with high antioxidant content. Gethuk is one of the traditional snacks in Indonesia. Gethuk is made from cassava with minimal processing such as boiling, destructing, and forming. Gethuk is classified as a familiar snack in the community, so it has a potential for developing, especially into a functional food. The low content of antioxidants in gethuk can be overcome with the development of a product called Gethuk Marillo. Gethuk Marillo is gethuk with the addition of natural antioxidants from mangosteen pericarp extract which has a high content of xanthones, these compounds are classified into flavonoids and act as antioxidants in the body. Gethuk Marillo served along with tamarillo fruit sauce which is also high in antioxidants such as anthocyanin. The combination between 300 grams gethuk Marillo and sauce contain flavonoid about 31% of human antioxidant needs per day. Gethuk Marillo called as a functional food because of high flavonoids content which can prevent degenerative diseases namely cancer, as many studies that the xanthone and anthocyanins compounds can effectively prevent the formation of cancer cells in human body. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gethuk%20marillo" title="Gethuk marillo">Gethuk marillo</a>, <a href="https://publications.waset.org/abstracts/search?q=xanthones" title=" xanthones"> xanthones</a>, <a href="https://publications.waset.org/abstracts/search?q=anthocyanin" title=" anthocyanin"> anthocyanin</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20antioxidants" title=" high antioxidants"> high antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-cancer" title=" anti-cancer"> anti-cancer</a> </p> <a href="https://publications.waset.org/abstracts/19634/gethuk-marillo-the-new-product-development-of-anti-cancer-snacks-utilizing-xanthones-and-anthocyanin-in-mangosteen-pericarp-and-tamarillo-fruit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19634.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">655</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">7</span> Productivity, Phenolic Composition and Antioxidant Activity of Arrowroot (Maranta arundinacea)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maira%20C.%20M.%20Fonseca">Maira C.

Arrowroot (Maranta arundinacea) is a NCPF from which starch is extracted from rhizome do not have gluten. Thus, arrowroot flower starch can be consumed by celiac people. Additional, some medicinal and functional proprieties are assigned to arrowroot leaves which currently are underutilized. In Brazil, it’s cultivated mainly by small scale farmers and there is no specific recommendation for fertilization. This work aimed to determinate the best fertilization for rhizome production and to verify its influence in phenolic composition and antioxidant activity of leaf extracts. Two arrowroot varieties, “Common” and “Seta”, were cultivated in organic system at state of Minas Gerais, Brazil, using cattle manure with three levels of nitrogen (N) (0, 300 and 900 kg N ha-1). The experiment design was in randomized block with four replicates. The highest production of rhizomes in both varieties, “Common” (38198.24 kg ha-1) and “Seta” (43567.71 kg ha-1), were obtained with the use of 300 kg N ha-1. With this fertilization, the total aerial part, petiole and leaf production in the varieties were respectively: “Common” (190.312 kg ha-1; 159.312 kg ha-1; 31.100 kg ha-1) and “Seta” (207.656 kg ha-1; 180.539 kg ha-1; 27.062 kg ha-1). Methanolic leaf extracts were analysed by HPLC-DAD. The major phenolic compounds found were caffeioylquinic acids, p-coumaric derivatives and flavonoids. In general, the production of these compounds significantly decreases with the increase levels of nitrogen (900 kg N ha-1). With 300 kg N ha-1 the phenolic production was similar to control. The antioxidant activity was evaluated using DPPH method and was detected around 60% of radical scavenging when 0.1 mg/mL of plant extracts were used. We concluded that fertilization with 300 kg N ha-1 increased arrowroot rhizome production, maintaining phenolic compounds yield at leaves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title="antioxidant activity">antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=non-conventional%20plants" title=" non-conventional plants"> non-conventional plants</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20fertilization" title=" organic fertilization"> organic fertilization</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a> </p> <a href="https://publications.waset.org/abstracts/85811/productivity-phenolic-composition-and-antioxidant-activity-of-arrowroot-maranta-arundinacea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85811.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">204</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">6</span> Evaluation of the Shelf Life of Horsetail Stems Stored in Ecological Packaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Goncalves%20Das%20Dores">Rosana Goncalves Das Dores</a>, <a href="https://publications.waset.org/abstracts/search?q=Maira%20Fonseca"> Maira Fonseca</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Finger"> Fernando Finger</a>, <a href="https://publications.waset.org/abstracts/search?q=Vicente%20Casali"> Vicente Casali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Equisetum hyemale L. (horsetail, Equisetaceae) is a medicinal plant used and commercialized in simple paper bags or non-ecological packaging in Brazil. The aim of this work was to evaluate the relation between the bioactive compounds of horsetail stems stored in ecological packages (multi-ply paper sacks) at room temperature. Stems in primary and secondary stage were harvested from an organic estate, on December 2016, selected, measured (length from the soil to the apex (cm), stem diameter at ground level (DGL mm) and breast height (DBH mm) and cut into 10 cm. For the post-harvest evaluations, stems were stored in multi-ply paper sacks and evaluated daily to the respiratory rate, fresh weight loss, pH, presence of fungi / mold, phenolic compounds and antioxidant activity. The analyses were done with four replicates, over time (regression) and compared at 1% significance (Tukey test). The measured heights were 103.7 cm and 143.5 cm, DGL was 2.5mm and 8.4 mm and DBH of 2.59 and 6.15 mm, respectively for primary and secondary stems stage. At both stages of development, in storage in multi-ply paper sacks, the greatest mass loss occurred at 48 h, decaying up to 120 hours, stabilizing at 192 hours. The peak respiratory rate increase occurred in 24 hours, coinciding with a change in pH (temperature and mean humidity was 23.5°C and 55%). No fungi or mold were detected, however, there was loss of color of the stems. The average yields of ethanolic extracts were equivalent (approximately 30%). Phenolic compounds and antioxidant activity were higher in secondary stems stage in up to 120 hours (AATt0 = 20%, AATt30 = 45%), decreasing at the end of the experiment (240 hours). The packaging used allows the commercialization of fresh stems of Equisetum for up to five days. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=paper%20sacks" title="paper sacks">paper sacks</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20content" title=" phenolic content"> phenolic content</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title=" medicinal plants"> medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=post-harvest" title=" post-harvest"> post-harvest</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20packages" title=" ecological packages"> ecological packages</a>, <a href="https://publications.waset.org/abstracts/search?q=Equisetum" title=" Equisetum"> Equisetum</a> </p> <a href="https://publications.waset.org/abstracts/84696/evaluation-of-the-shelf-life-of-horsetail-stems-stored-in-ecological-packaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84696.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">166</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">5</span> Adequacy of Antenatal Care and Its Relationship with Low Birth Weight in Botucatu, São Paulo, Brazil: A Case-Control Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C%C3%A1tia%20Regina%20Branco%20da%20Fonseca">Cátia Regina Branco da Fonseca</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Wany%20Louzada%20Strufaldi"> Maria Wany Louzada Strufaldi</a>, <a href="https://publications.waset.org/abstracts/search?q=L%C3%ADdia%20Raquel%20de%20Carvalho"> Lídia Raquel de Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Fiorini%20Puccini"> Rosana Fiorini Puccini </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Birth weight reflects gestational conditions and development during the fetal period. Low birth weight (LBW) may be associated with antenatal care (ANC) adequacy and quality. The purpose of this study was to analyze ANC adequacy and its relationship with LBW in the Unified Health System in Brazil. Methods: A case-control study was conducted in Botucatu, São Paulo, Brazil, 2004 to 2008. Data were collected from secondary sources (the Live Birth Certificate), and primary sources (the official medical records of pregnant women). The study population consisted of two groups, each with 860 newborns. The case group comprised newborns weighing less than 2,500 grams, while the control group comprised live newborns weighing greater than or equal to 2,500 grams. Adequacy of ANC was evaluated according to three measurements: 1. Adequacy of the number of ANC visits adjusted to gestational age; 2. Modified Kessner Index; and 3. Adequacy of ANC laboratory studies and exams summary measure according to parameters defined by the Ministry of Health in the Program for Prenatal and Birth Care Humanization. Results: Analyses revealed that LBW was associated with the number of ANC visits adjusted to gestational age (OR = 1.78, 95% CI 1.32-2.34) and the ANC laboratory studies and exams summary measure (OR = 4.13, 95% CI 1.36-12.51). According to the modified Kessner Index, 64.4% of antenatal visits in the LBW group were adequate, with no differences between groups. Conclusions: Our data corroborate the association between inadequate number of ANC visits, laboratory studies and exams, and increased risk of LBW newborns. No association was found between the modified Kessner Index as a measure of adequacy of ANC and LBW. This finding reveals the low indices of coverage for basic actions already well regulated in the Health System in Brazil. Despite the association found in the study, we cannot conclude that LBW would be prevented only by an adequate ANC, as LBW is associated with factors of complex and multifactorial etiology. The results could be used to plan monitoring measures and evaluate programs of health care assistance during pregnancy, at delivery and to newborns, focusing on reduced LBW rates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20birth%20weight" title="low birth weight">low birth weight</a>, <a href="https://publications.waset.org/abstracts/search?q=antenatal%20care" title=" antenatal care"> antenatal care</a>, <a href="https://publications.waset.org/abstracts/search?q=prenatal%20care" title=" prenatal care"> prenatal care</a>, <a href="https://publications.waset.org/abstracts/search?q=adequacy%20of%20health%20care" title=" adequacy of health care"> adequacy of health care</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20evaluation" title=" health evaluation"> health evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health%20system" title=" public health system"> public health system</a> </p> <a href="https://publications.waset.org/abstracts/14956/adequacy-of-antenatal-care-and-its-relationship-with-low-birth-weight-in-botucatu-sao-paulo-brazil-a-case-control-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14956.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">4</span> Environmental Law and Payment for Environmental Services: Perceptions of the Family Farmers of the Federal District, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kever%20Bruno%20Paradelo%20Gomes">Kever Bruno Paradelo Gomes</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Carvalho%20Cristo%20Martins"> Rosana Carvalho Cristo Martins</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Payment for Environmental Services (PSA) has been a strategy used since the late 1990s by Latin American countries to finance environmental conservation. Payment for Environmental Services has been absorbing a growing amount of time in the discussions around environmentally sustainable development strategies in the world. In Brazil, this theme has permeated the discussions since the publication of the new Forest Code. The objective of this work was to verify the perception of the resident farmers in the region of Ponte Alta, Gama, Federal District, Brazil, on environmental legislation and Payments for Environmental Services. The work was carried out in 99 rural properties of the family farmers of the Rural Nucleus Ponte Alta, Administrative Region of Gama, in the city of Brasília, Federal District, Brazil. The present research is characterized methodologically as a quantitative, exploratory, and descriptive nature. The data treatment was performed through descriptive statistical analysis and hypothesis testing. The perceptions about environmental legislation in the rural area of Ponte Alta, Gama, DF respondents were positive. Although most of the family farmers interviewed have some knowledge about environmental legislation, it is perceived that in practice, the environmental adequacy of property is ineffective given the current situation of sustainable rural development; there is an abyss between what is envisaged by legislation and reality in the field. Thus, as in the reports of other researchers, it is verified that the majority of respondents are not aware of PSA (62.62%). Among those interviewed who were aware of the subject, two learned through the course, three through the university, two through TV and five through other people. The planting of native forest species on the rural property was the most informed practice by farmers if they received some Environmental Service Payment (PSA). Reflections on the environment allow us to infer that the effectiveness and fulfillment of the incentives and rewards in the scope of public policies to encourage the maintenance of environmental services, already existing in all spheres of government, are of great relevance to the process of environmental sustainability of rural properties. The relevance of the present research is an important tool to promote the discussion and formulation of public policies focused on sustainable rural development, especially on payments for environmental services; it is a space of great interest for the strengthening of the social group dedicated to production. Public policies that are efficient and accessible to the small rural producers become decisive elements for the promotion of changes in behavior in the field, be it economic, social, or environmental. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forest%20code" title="forest code">forest code</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20policy" title=" public policy"> public policy</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20development" title=" rural development"> rural development</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20agriculture" title=" sustainable agriculture"> sustainable agriculture</a> </p> <a href="https://publications.waset.org/abstracts/109705/environmental-law-and-payment-for-environmental-services-perceptions-of-the-family-farmers-of-the-federal-district-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109705.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">151</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">3</span> Most Recent Lifespan Estimate for the Itaipu Hydroelectric Power Plant Computed by Using Borland and Miller Method and Mass Balance in Brazil, Paraguay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anderson%20Braga%20Mendes">Anderson Braga Mendes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Itaipu Hydroelectric Power Plant is settled on the Paraná River, which is a natural boundary between Brazil and Paraguay; thus, the facility is shared by both countries. Itaipu Power Plant is the biggest hydroelectric generator in the world, and provides clean and renewable electrical energy supply for 17% and 76% of Brazil and Paraguay, respectively. The plant started its generation in 1984. It counts on 20 Francis turbines and has installed capacity of 14,000 MWh. Its historic generation record occurred in 2016 (103,098,366 MWh), and since the beginning of its operation until the last day of 2016 the plant has achieved the sum of 2,415,789,823 MWh. The distinct sedimentologic aspects of the drainage area of Itaipu Power Plant, from its stretch upstream (Porto Primavera and Rosana dams) to downstream (Itaipu dam itself), were taken into account in order to best estimate the increase/decrease in the sediment yield by using data from 2001 to 2016. Such data are collected through a network of 14 automatic sedimentometric stations managed by the company itself and operating in an hourly basis, covering an area of around 136,000 km² (92% of the incremental drainage area of the undertaking). Since 1972, a series of lifespan studies for the Itaipu Power Plant have been made, being first assessed by Sir Hans Albert Einstein, at the time of the feasibility studies for the enterprise. From that date onwards, eight further studies were made through the last 44 years aiming to confer more precision upon the estimates based on more updated data sets. From the analysis of each monitoring station, it was clearly noticed strong increase tendencies in the sediment yield through the last 14 years, mainly in the Iguatemi, Ivaí, São Francisco Falso and Carapá Rivers, the latter situated in Paraguay, whereas the others are utterly in Brazilian territory. Five lifespan scenarios considering different sediment yield tendencies were simulated with the aid of the softwares SEDIMENT and DPOSIT, both developed by the author of the present work. Such softwares thoroughly follow the Borland & Miller methodology (empirical method of area-reduction). The soundest scenario out of the five ones under analysis indicated a lifespan foresight of 168 years, being the reservoir only 1.8% silted by the end of 2016, after 32 years of operation. Besides, the mass balance in the reservoir (water inflows minus outflows) between 1986 and 2016 shows that 2% of the whole Itaipu lake is silted nowadays. Owing to the convergence of both results, which were acquired by using different methodologies and independent input data, it is worth concluding that the mathematical modeling is satisfactory and calibrated, thus assigning credibility to this most recent lifespan estimate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Borland%20and%20Miller%20method" title="Borland and Miller method">Borland and Miller method</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroelectricity" title=" hydroelectricity"> hydroelectricity</a>, <a href="https://publications.waset.org/abstracts/search?q=Itaipu%20Power%20Plant" title=" Itaipu Power Plant"> Itaipu Power Plant</a>, <a href="https://publications.waset.org/abstracts/search?q=lifespan" title=" lifespan"> lifespan</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20balance" title=" mass balance"> mass balance</a> </p> <a href="https://publications.waset.org/abstracts/68683/most-recent-lifespan-estimate-for-the-itaipu-hydroelectric-power-plant-computed-by-using-borland-and-miller-method-and-mass-balance-in-brazil-paraguay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68683.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">274</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">2</span> Agriculture and Forests: A Perception of Farmers on Sustainable Agro-Ecological Practices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kever%20Gomes">Kever Gomes</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Martins"> Rosana Martins</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of environmental indicators is today an important strategy for analyzing the sustainability of agricultural systems. Despite of the considerable importance of family agriculture for Brazilian economy, sustainable agricultural practices are still weakly known, and the known ones, underused. Currently, economic aspects of the relationship between man and nature lead to the destruction of natural ecosystems, which justifies the urgent need for dissemination and usage of new sustainable production techniques. The study shows the agro-social and social-cultural trajectory of the farmers and hypothesis are advanced on what would imply the adoption of agroforestry systems in family agriculture. This study aimed to investigate aspects related to the perception of sustainable agriculture, especially on agroforestry systems in farms of farmers from Distrito Federal-Brazil. Agro-social characteristics of farmers were systematized considering their perceptions about agroforestry systems for the preparation of proposal for a program of Environmental Services Payment, intended for families who are involved in the various activities of home gardens. This study used qualitative methodological approaches of quantitative research, using descriptive exploratory research. To get the necessary elements for the intended analysis, interviews were conducted at 40 heads of households of which 15 were men and 25 women. The results were analyzed using descriptive statistics, having been considered in the analysis the frequency, consistency, coherence and originality of responses. It was found that the lack of financial resources and lack of technical assistance are limiting factors for the dissemination and use of sustainable agricultural practices. Considering the great number of species found for the main categories of use, it can be inferred that the home gardens play important functions for the interviewed families, contributing for the food and medicine production destined for the consumption by the families themselves, and also playing an important esthetic function thanks to the variety of their ornamental plants. The wealth of these home gardens may be related to the rural origin and to the culture of the owners, who still keep a cultivation tradition. It was found that the products obtained from the home gardens contributed for the diet’s variety of the informants, representing a promising potential for the improvement of the population alimentation. The study reached the conclusion over the need to motivate the interest of these farmers to seek information and resources to enable the implementation of Agroforestry projects, including the recovery of areas in their properties, even those distinct from their backyards. The study shows the agro-social and social-cultural trajectory of the farmers and hypothesis are advanced on what would imply the adoption of agroforestry systems in family agriculture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agro-biodiversity" title="agro-biodiversity">agro-biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20conservation" title=" natural conservation"> natural conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=silviculture" title=" silviculture"> silviculture</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20agriculture" title=" urban agriculture"> urban agriculture</a> </p> <a href="https://publications.waset.org/abstracts/75589/agriculture-and-forests-a-perception-of-farmers-on-sustainable-agro-ecological-practices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75589.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">195</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">1</span> Diversity and Use of Agroforestry Yards of Family Farmers of Ponte Alta – Gama, Federal District, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kever%20Bruno%20Paradelo%20Gomes">Kever Bruno Paradelo Gomes</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Carvalho%20Martins"> Rosana Carvalho Martins</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The home gardens areas are production systems, which are located near the homes and are quite common in the tropics. They consist of agricultural and forest species and may also involve the raising of small animals to produce food for subsistence as well as income generation, with a special focus on the conservation of biodiversity. Home gardens are diverse Agroforestry systems with multiple uses, among many, food security, income aid, traditional medicine. The work was carried out on rural properties of the family farmers of the Ponte Alta Rural Nucleus, Gama Administrative Region, in the city of Brasília, Federal District- Brazil. The present research is characterized methodologically as a quantitative, exploratory and descriptive nature. The instruments used in this research were: bibliographic survey and semi-structured questionnaire. The data collection was performed through the application of a semi-structured questionnaire, containing questions that referred to the perception and behavior of the interviewed producer on the subject under analysis. In each question, the respondent explained his knowledge about sustainability, agroecological practices, environmental legislation, conservation methods, forest and medicinal species, ago social and socioeconomic characteristics, use and purpose of agroforestry and technical assistance. The sample represented 55.62% of the universe of the study. We interviewed 99 people aged 18-83 years, with a mean age of 49 years. The low level of education, coupled with the lack of training and guidance for small family farmers in the Ponte Alta Rural Nucleus, is one of the limitations to the development of practices oriented towards sustainable and agroecological agriculture in the nucleus. It is observed that 50.5% of the interviewed people landed with agroforestry yards less than 20 years ago, and only 16.17% of them are older than 35 years. In identifying agriculture as the main activity of most of the rural properties studied, attention is drawn to the cultivation of medicinal plants, fruits and crops as the most extracted products. However, it is verified that the crops in the backyards have the exclusive purpose of family consumption, which could be complemented with the marketing of the surplus, as well as with the aggregation of value to the cultivated products.
