Segundo a Confederação Brasileira de Basquetebol (CBB), o basquete é um esporte popular, praticado em todo o mundo por mais de 300 milhões de pessoas. Manoel Tubino (2001, p. 57), aponta é um fenômeno social que atingiu níveis muito complexos de desenvolvimento nas diversas sociedades. Sobre o jovem atleta Cratty (1984) destaca que este acaba vivenciando situações em que seu rendimento, tanto sendo um sucesso como um fracasso se torne visível perante a sociedade, deixando que os sentimentos emocionais e psíquicos se aflorem junto com os fisiológicos influenciando no desempenho. Entre os vários fatores intra e extra quadra que podem influenciar no resultado, estão os aspectos psicológicos e os pensamentos automáticos. Para Cecarelli (2011) um dos fatores que mais afetam os atletas é a ansiedade e está diretamente ligado, a importância da competição e de cada jogo, distância de casa, viagem, mudança de hábitos, adaptação ao clima e fuso horário, entre outros aspectos que provocam possível processamento errôneo do pensamento automático e um aumento da ansiedade. Desta maneira torna-se imprescindível destacar que os aspectos fisiológicos e psicológicos de jovens atletas não se encontram eficientemente maduros para lidar com cobranças e pressões advindas do meio esportivo, cabendo aos sujeitos envolvidos na prática do basquetebol (técnicos, diretores, pais, patrocinadores, psicólogo do esporte e atletas) fazer uso da psicologia do esporte a fim de objetivar-se um bom rendimento. O objetivo deste estudo foi compreender como se dá a relação entre os pensamentos automáticos e a ansiedade. A metodologia deste estudo pautou-se em uma revisão de literatura utilizando os principais referenciais teóricos que circunscrevem os temas principais deste trabalho. Segundo Beck (2005) é tão possível perceber um pensamento, focar nele e avaliá-lo, como é possível identificar e refletir sobre uma sensação...

The aim of this study was to evaluate whether digitized images obtained from periapical radiographs taken with low dose of radiation could be improved with the aid of a computer software (PhotoStyler) for digital treatrnent. Serial and standardized radiographs of molar and premolar areas were studied. A total of 57 images equivalent to the radiographs taken with reduced exposure time ( 60 and 80% of the time considered normal), digitized and treated, were submitted to the evaluation of seven exanúners which compared them with those images without treatment. lt was verified that about 80% of the images equivalem to lhe radiographs taken with 60% reduction of ordinary exposure time were considered to having quality for supporting diagnosis. As for the images taken with 80% reduction of ordinary exposure time, about 50% of them were considered suitable for the sarne purpose

The aim of this study was to compare the quality of clarifi ed juice and VHP (Very High Purity) sugar produced from “bisada” sugarcane and an early maturation variety, at the beginning of harvest. The experiment was conducted at Usina São Martinho S/A, Pradópolis,SP (Brazil). The process of juice clarifi cation and sugar production was conducted at the Laboratory of Technology of Sugar and Alcohol in the College of Agricultural and Veterinary Sciences at the Universidade Estadual Paulista (FCAV/UNESP), Jaboticabal (SP). The experimental design was randomized, and two varieties were used: SP83-2847 (“bisada” sugarcane) and RB855156 (early maturation), with twelve replications for technological analysis and four replications for sugar production. The clarifi cation process and the clarifi ed juice was evaluated in terms of settling rates, volume of sludge that formed, total soluble solids, pH, turbidity, total phenolic compounds, starch and color. The sugar was characterized regarding the percentage of apparent sugar, color, total phenolic compounds, starch, fi lterability, humidity and safety factor. It was verifi ed that the processing of the juice clarifi cation was not affected by the processing of the “bisada” sugarcane. However, the clarifi ed juice from the SP83-2847 variety had a more intense color and a higher total soluble solids value. The sugar produced from the “bisada” sugarcane presented similar quality to the early maturation variety. It was concluded that the processing of “bisada” sugarcane at the start of the harvest did not affect the juice clarifi cation and resulted in VHP sugar of a quality similar to that of the early maturation variety.

Okara is a residue of production process of soy milk, wich has a considered nutritional value for containing proteins, lipids and fi bers in signifi cant amount, besides bioactive compounds, such as isofl avone. Despite these qualities, the great amount of okara produced annually in Brazil and in other countries generates a problem of disposal waste and it has served only for animal food products. Such situation can be changed by studies, that demonstrate the viability of okara’s utilization in human nourishment. Thus, the purpose of this research was to develop a fermented hamburger with a probiotic bacteria, based on chicken meat and okara fl our. Five formulations were processed: F1-100% of chicken meat, unfermented and containing curing salts, F2-100% of chicken meat, fermented with L. acidophilus, F3 - 90% of chicken meat and 10% of okara meal, fermented with L. acidophilus, F4 - 70% of chicken meat and 30% of okara meal, fermented with L. acidophilus; F5 - 50% of chicken meat and 50% of okara meal, fermented with L. acidophilus. All formulations were evaluated for the viability of the probiotic culture, determination of cooking yield and shrinkage percentage, pH and sensory characteristics. The results have demonstrated that it is possible to elaborate a chicken hamburger, fermented with Lactobacillus acidophilus CRL 1014, with the addition of 10% okara fl our.

Os seres humanos identificam naturalmente outros seres humanos utilizando suas características físicas, fisiológicas ou comportamentais. Dentre essas características, destacam-se os traços faciais. O avanço tecnológico na área de Biometria tem promovido o desenvolvimento de inúmeras técnicas para o reconhecimento automático de faces por meio de computadores, entretanto, existem ainda vários fatores que dificultam esta aplicação, como por exemplo, a variação das condições de iluminação. O objetivo deste artigo é analisar os efeitos da aplicação de um filtro de processamento de imagens, denominado Transformada Census, em uma base de dados com imagens da face em diferentes condições de iluminação. Assim, experimentos foram realizados utilizando a técnica PCA com imagens da base de dados AR antes e depois da aplicação da Transformada Census. Os resultados desses experimentos mostraram que a aplicação da Transformada Census melhorou o resultado do reconhecimento das faces, reduzindo a taxa de erro.

Aiming to get the best economic advantage in ethanol production from cassava roots, this study presented a physiochemical characterization from two different types of solid waste in two types of processing of the raw materials in manufacturing ethanol. The processing of cassava roots begins with the disintegration and washing the roots with the addition of 20% more water to obtain a pulp which was treated and stirred in the reactor while adding enzyme α-amylase at a temperature of 90°C for 2 hours. Then we performed a pH adjustment while lowering the temperature to 60 ° C with the addition of the enzyme amiloglucosidase and then stirring for 14 hours. The hydrolyzate obtained was the source of two types of waste which are: i) Solid residue obtained after filtration of the hydrolyatze and ii) Solid waste obtained from filtering wine after alcoholic fermentation of the hydrolyzate with the addition of a dried yeast strain Y-940 manufactured by MAURI OF BRAZIL SA (2%) at a temperature of 25º C. The results of the laboratory analysis showed that the byproducts derived from the hydrolysis and fermentation showed very similar chemical compositions. With levels between 39 and 41% fiber, 0.5% lipids, 20 and 30% carbohydrates, protein 0.5 and 1.50, 6 and 8% acidity, and 20 and 30% soluble solids.

The use of computer-assisted technologies such as CAD - Computed Aided Design, CAM - Computed Aided Manufacturing, CAE - Computed Aided Engineering and CNC - Computed Numerical Control, are priorities in engineering and product designers. However, the dimensional measurement between the virtual and the real product design requires research, and dissemination procedures among its users. This work aims to use these technologies, through analysis and measurement of a CNC milling machine, designed and assembled in the university. Through the use of 3D scanning, and analyzing images of the machined samples, and its original virtual files, it was possible to compare the sizes of these samples in counterposition to the original virtual dimensions, we can state that the distortions between the real and virtual, are within acceptable limits for this type of equipment. As a secondary objective, this work seeks to disseminate and make more accessible the use of these technologies.
