Uso do ATP para simulações de descargas atmosféricas em para-raios de 15 kV dos serviços auxiliares de subestações de energia elétrica

This paper addresses the topics required for the selection of surge arresters used, the output of autotransformers, which protect the system Auxiliary Services (SE) of an electrical substation. Surge arresters used are part of the Protection System Lightning (SPDA). Transmission lines mostly run through regions with orographic well diversified and have constant weather changes, which lead to many undesirable interactions with electromagnetic phenomena, such as giving rise to blackout on 10 November 2009, which left nine states without power, which led to unplanned shutdowns in the system that left millions of people without electricity. This work of completion is to determine whether the method used in the selection of surge arresters meet the protection needs faced by a substation auxiliary services, through the use of software use ATPDraw

Uma proposta de intervenção com atividade física individualizada na deficiência intelectual: um estudo de caso

The practice of regular physical activity has been considered a protective factor against the degenerative processes of the body, acting as a promoter of health, especially for risk groups such as obese and resistant groups exercise adherence as among the intellectually disabled (ID) . This study involved the administration of a training protocol and the physical parameters of longitudinal health in a subject about 43 years, intellectually deficient, hypertensive, obese and with a strong predisposition to develop diabetes and heart disease. The main objective of long-term program was to reduce body weight and normalize blood pressure (BP) after the student's physical activity and preferentially interfere with BP values at rest (ie before the daily schedule). The other objective was to improve general physical fitness. The protocol involved four meetings per week lasting one hour, in addition to participation in the program PROEFA (twice a week with sessions of one hour each), totaling 57 sessions spread over five months. The evaluation protocol included in each session the following tests: blood pressure measurements and heart rate, and amount of physical activity recorded via pedometer. Tests applied before and after the training included: anthropometric assessment, agility test, flexibility test, test drive through vertical and horizontal jumps and endurance to the test bench. The mass (kg) and BMI corresponded to the initial values of 127.7 kg and 42.05 kg m-2, and 5 months after 113.2 kg and 37.48 kg m-2, respectively. The waist-hip ratio was close to 1 after the intervention and this value corresponded to 0.98. For the test of agility (shuttle run) was not found improvement in performance. To test the values of the horizontal jump in pre-test were 52 cm and 56 cm post-test, vertical jump has been improved and...(Complete abstract click electronic access below)

Sistema biométrico de identificação de pessoas utilizando poros e minúcias de impressões digitais

The use of physical characteristics for human identification is known as biometrics. Among the many biometrics traits available, the fingerprint is the most widely used. The fingerprint identification is based on the impression patterns, as the pattern of ridges and minutiae, characteristics of first and second levels respectively. The current identification systems use these two levels of fingerprint features due to the low cost of the sensors. However, the recent advances in sensor technology, became possible to use third level features present within the ridges, such as the perspiration pores. Recent studies show that the use of third-level features can increase security and fraud protection in biometric systems, since they are difficult to reproduce. In addition, recent researches have also focused on multibiometrics recognition due to its many advantages. The goal of this research project was to apply fusion techniques for fingerprint recognition in order to combine minutia, ridges and pore-based methods and, thus, provide more robust biometrics recognition systems, and also to develop an automated fingerprint identification system using these three methods of recognition. We evaluated isotropic-based and adaptive-based automatic pore extraction methods, and the fusion of pore-based method with the identification methods based on minutiae and ridges. The experiments were performed on the public database PolyUHRF and showed a reduction of approximately 16% in the EER compared to the best results obtained by the methods individually

Viabilidade do aproveitamento de resíduos de madeira para produção de móveis

The need to use waste from wood processing industry grows due to environmental demands imposed by laws, so like the need to introduce more competitive products in the market (it means better quality and acceptable cost) who must submit by the rational use of raw material, usually turning waste to sub products, what adds higher value for that. To this research, specific case from Ribon Company, located on Camaçari, Bahia-Brazil, has been studied. It is a treated wood producer. Bulk of monthly wood logs there is 70 m3. Its yield is 71,43%, where bulk of generated waste is monthly 20m3. As an exploitation way from generated waste, it has been suggested some options like: erosion protection to specific areas, a wildlife shelter as an henhouse etc, recreational articles, coal, linings, treadmills. However this research will give focus to the furniture design made of waste. As a conclusion, there is very much need to assign new utilizations to that sub used materials, since there is significant amount to increase company’s productive yield

Compostos fenólicos de 10 variedades de uva

Phenolic compounds represent one of the main groups of secondary metabolites. Due to their chemical diversity, they have a variety of functions in plants, such as protection against ultraviolet radiation, herbivores and pathogens, and attraction of pollinators or dispersers of fruits and seeds. For human, the phenolic compounds are used like food colorings and flavors and, due to their pharmacological properties, mainly to antioxidant activity, they are associated with several health benefits, such as delay senility, prevention and therapy of cardiovascular diseases and of some cancers. The grapes are considered one of the main source of phenolic compounds and the fruit and its products are consumed in Brazil and worldwide. Considering the phenolic compounds diversity and their different distribution in the grape parts, this work had like aims the extraction, identification and quantification of the main classes of phenolic compounds of 10 grape varieties. The content of total phenols, flavanols and anthocyanins were determined, respectively, according to the Folin-Ciocalteu, DMACA and comparison of pH spectrophotometric methods. The content of total phenols varied from 142.75 + 1.86 to 483.39 + 5.90 mg.L-1 in the peel and from 86.50 + 0.54 to 146.32 + 9.97 mg.L-1 in the pulp. The amount of total flavanols varied from 3.68 + 0.03 to 6.92 + 0.26 mg.L-1 in the peel and from 0.90 + 0.00 to 1.36 + 0.00 mg.L-1 in the pulp. The content of total anthocyanins varied from 7.00 + 0.99 to 406.56 + 39.50 mg.L-1 in the peel and from 2.88 + 0.28 to 46.36 + 1.89 mg.L-1 in the pulp. The phenolic compounds concentration was higher in the peel than in the pulp. The total phenols and anthocyanins varied a lot while the total flavanols were more constant. The flavanols represent the smaller portion of phenolic compounds

Estudo da velocidade de despassivação de aços em estruturas de concreto armado, em meio de cloreto

The aim of the present study was to investigate the corrosion resistance in chloride medium of two cylindrical steel samples from civil construction (CA-50 and CA-60). For this purpose, electrochemical measurements were performed in NaCl solution, 4.0 g/L, naturally aerated. According to electrochemical responses, it was observed an active dissolution process at open circuit potential for both steels. In this comparative study, the differences between CA-50 and CA60 were not significant, since the values of polarization resistance estimated by EIS were the same order of magnitude for both types of steel (oscillating between 200 and 500 Ohm). For all evaluated thicknesses of concrete reinforcement, these values ranged between 2 and 9 kOhm, and the lower value was associated with lower thickness, particularly at 7, 21 and 35 days. When these results were compared with those determined for the CA-60, it was found that the layer of concrete reinforcement provide a protection against corrosion in chloride medium at least ten times larger

Filmes de gelana e pectina reticuladas ionicamente para liberação colônica

O cólon tem sido explorado nas últimas décadas como sítio de liberação de fármacos. A goma gelana e a pectina são polissacarídeos hidrofílicos naturais promissores para a obtenção de sistemas de liberação cólon-específica de fármacos, uma vez que são degradados especificamente por enzimas produzidas pela microbiota deste órgão. Filmes poliméricos apresentam grande aplicação no revestimento de formas farmacêuticas sólidas e podem permitir o controle das taxas de liberação de fármacos e/ou seu direcionamento para um órgão específico. Além disso, modificações químicas como a reticulação iônica podem alterar propriedades físico-químicas como reduzir a hidrofilia do sistema. Neste trabalho foram obtidos e caracterizados filmes de goma gelana e pectina reticuladas ionicamente com cátion trivalente (Al3+). Os efeitos da concentração de polímeros, agente reticulante e plastificante (glicerol) utilizados na preparação das amostras foram avaliados a partir da caracterização das propriedades mecânicas, físicas e químicas dos filmes. A análise macroscópica revelou filmes flexíveis, homogêneos e translúcidos e a análise por microscopia eletrônica de varredura mostrou que a reticulação contribuiu para a formação de filmes com superfícies rugosas. Os baixos valores de transmissão de vapor d'água obtidos indicam a possibilidade de uma importante proteção contra a umidade. A absorção de líquido pH-dependente dos filmes foi demonstrada e a menor absorção de líquido em meio ácido deve garantir uma proteção da forma farmacêutica, quando em contato com o meio gástrico. Os filmes se mostraram bastante mucoadesivos, o que deve favorecer a retenção da forma farmacêutica no sítio alvo e as características mecânicas se mostraram favoráveis para a elaboração de filmes para revestimento de formas farmacêuticas sólidas
