Determinação da crítica razão esforço-pausa em Uchi-Komi no judô, com a utilização de deltas de variação de lactato sanguíneo e da escala subjetiva de esforço de Borg

In the competitive judo, the form as a trainer organizes the process of his/her athlete's training is a very important task for a good acting and a better use of the technical procedures. There is great importance in determining the exercise intensity for the judocas training due to the interest for the high income in several competitions, and few studies returned for this research area, involving those athletes' different physiologic conditions. Therefore, it is necessary to improve protocols of physical evaluation for this modality, increasing his/her applicability. The present study aimed at to verify the validity of a protocol of specific aerobic test of the judo (technique ipon-seoi-nague), no exhausting, adapted of the method of CHASSAIN (1986), using deltas of variations of the lactacidemia and of the Scale of Perception of Effort of Borg, in athletes well. The test adapted to the judo constituted of four exercise series with two efforts similar (double) of 180 seconds with one interval of 90 seconds among them. The series of exercises were accomplished in consecutive days. The intensities of the double tests were of 85%, 95%, 105% and 115% of the minimum lactato for each participant. This work used the technique ipon-seoi-nague, obeying the reasons effort-pause individualized for each athlete, that you/they correspond to the intensities of exercises proposed by the protocol of CHASSAIN (1986). In that way, the athletes applied a blow (maximum speed) and they rested some seconds, depending on the regime effort-pause of the session. At the end of each collection collection of blood (25NL) of each participant's earlobe was accomplished, seeking to measure the concentration of sanguine lactato. The collections were accomplished at the end of the first and of the second efforts, in each one of the series. For the analysis of the Perception of the athletes' Effort, the Scale of Perception...

Eles e Elas: comparação intersexual na categorização social e formação das primeiras impressões em seres humanos

O objetivo da presente pesquisa foi compreender, sob uma perspectiva evolucionista, os mecanismos, preferências e as diferenças sexuais subjacentes a uma análise as primeiras impressões em seres humanos. Investigamos: (1) ocorrências de diferenças sexuais na categorização social e na formação das primeiras impressões; (2) a influência do sexo e da cor de pele e (3) ocorrência de preconceitos (com relação ao sexo e/ou a cor de pele do sujeito estímulo) e suas influências na formação das primeiras impressões. Para isso, tratamos de expor uma amostra de 43 indivíduos ( 17 a 34 anos) à oito vídeos (4 perfis: homens negros e brancos, mulheres brancas e negras) com duração de 20’’ cada. Durante o procedimento experimental foi requerido que o participante respondesse a um questionário (escala likert; 0-6). Nesse, o participante avaliava a atratividade física, a competência, sucesso na carreira, agressividade, confiabilidade, atribuía uma nota para a cor da pele, e qualidade geral. Foi feito um teste GLM com medidas repetidas e post hoc teste t student pareado, a fim fazer uma análise mais detalhada das diferenças encontradas nas avaliações. Nossos resultados apontam que a característica que afeta mais a avaliação tanto de homens como das mulheres é a atratividade física, o que foi possível concluir que as outras características em análise é menos dependente da primeira impressão e construída ao longo do convívio. As mulheres tendem a fazer uma avaliação mais minuciosa, o que corrobora outros estudos sobre diferenças sexuais. Devido ao pequeno N, não possível analisarmos a influência da cor da pele do sujeito estímulo na avaliação, evidenciando a necessidade de ampliação futura desse projeto. A análise post hoc nos mostrou um ligeiro preconceito contra as mulheres negras, o que também corrobora... (Resumo completo, clicar acesso eletrônico abaixo)

Geologic and geomorphologic mapping are important ways to characterize the environment, because they look to describe and diagnose landforms, identifying and understanding the morphogenetic processes, making it possible to comprehend the landscape dynamic. This work aimed to make a geological and geomorphological map, in a 1:10.000 scale, of the Morro Azul, the main elevation in the city of Limeira – SP, with the application of photogeological techniques and field descriptions. As final products are presented a geological-geomorphological map, a topographical profile, a slope map, beyond the main characteristics of the geological-geomorphological units of the area. This study presents itself as a preliminary work, and can serve as a subsidy to more specific works, such as geotechnics, environmental problems, among others

Investigação do tratamento de água de máquina de lavar roupa empregando reator biológico, em escala piloto, visando redução da concentração de fósforo para reúso não potável

This research aims at the study of treatment of clothes washing water through biological treatment, for the purpose of evaluating the reduction of phosphorus to make it suitable for a posterior treatment of physical-chemical. For this purpose it was employed a sequencing batch reactor, consisting of aerobic and anaerobic phases. During the project it was verified not only the reduction of phosphorus (removal of 30 to 50%) but also the reduction of BOD, COD, Turbidity and Nitrate (removal of 38 to 36%, 34 to 41%, 72,3 to 75% and 57,8 to 60% respectively), which demonstrates that the proposed treatment can assist advanced treatments of water for its non potable reuse

Tratamento de água pluvial para fins não potáveis com utilização de amido de milho como coagulante em filtração cíclica em escala de laboratório

The aim of the present work is to investigate a simplified rainwater treatment strategy for nonpotable use. For this, there were simulated in laboratory scale the treatment conditions of a system that employs Corn Starch as a coagulant in cyclic filtration (from 1 to 5 filtration cycles). A commercial Corn Starch in different dosages was used (0,1; 0,2; 0,4; 0,6; 0,8; 1,0; 1,5; 2,0; 2,5; 3,0; 3,5; 4,0; 4,5; 5,0; 5,5; 6,0; 6,5; 7,0; 7,5; 8,0; 8,5 e 9,0 mg/L). The NBR 15527/07 recommended parameters were monitored on the inflow and outflow and compared to different first flushes (0.5; 1.0 and 1.5mm). The obtained results indicate that the 6.0mg/L dosage presented the best results (removal efficiency of 86% of turbidity; 88% of apparent color and absent of total and faecal coliform residuals). However, it was not possible to prove the filtration cycles benefit, in laboratory scale, because for some Corn Starch dosages the water did not present better quality when increasing the number of cycles.

Determinação da crítica razão esforço pausa (e:pcrit) em uchi-komi no judô, utilizando deltas de variação de freqüência cardíaca e escala de percepção de esforço de Borg

O presente estudo objetivou verificar a validade de um protocolo de teste aeróbio específico do judô (técnica ipon-seoi-nague), não exaustivo, adaptado do método de CHASSAIN (1986), utilizando deltas de variações da escala de percepção de Borg e da freqüência cardíaca em atletas bem treinados. O teste adaptado ao judô constituiu de quatro séries de exercício com dois esforços iguais (duplos) de 180 segundos com um intervalo de 90 segundos entre eles. As séries de exercícios foram realizadas em dias consecutivos. As intensidades dos testes duplos foram de 85%, 95%,105% e 115% do lactato mínimo para cada participante. Este trabalho utilizou a técnica ipon-seoi-nague, sendo que as razões esforço-pausa foram específicas para cada atleta, e correspondem às intensidades de exercício propostas pelo protocolo de Chassain (1986). A escala de percepção de esforço de Borg foi mostrada ao final do primeiro e do segundo esforços, em cada uma das séries, para que o atleta determinasse o nível de cansaço. Para análise da freqüência cardíaca foi utilizado um freqüencímetro, Polar Vantage NV, obtendo freqüência cardíaca concomitantemente a escala de Borg, ao final de bloco de esforço. Dessa maneira, foram obtidos dois deltas de variações entre o primeiro e o segundo esforços, para escala de percepção de Borg (ΔBORG) e FC (ΔFC). Uma vez que foram utilizadas quatro intensidades, foi possível determinar quatro ΔBORG e quatro ΔFC. Assim, a partir de duas regressões lineares (uma para o Borg e outra para a FC), foi possível determinar as razões esforço:pausas críticas do exercício na técnica específica do Judô, a partir da determinação das intensidades nas quais a variação de Borg e da FC foi igual a zero (ΔBORG=0 e ΔFC=0). Para validar esses procedimentos adaptados de Chassain (1986) ao Judô, foi realizado o teste de Lactato Mínimo Adaptado, conforme sugerido por Azevedo (2002).

Um estudo sobre a resolução de problemas e suas relações com a afetividade

This research aims at examining the relationship between the performance of elementary school students Cycle I in problem solving and attitudes toward mathematics. For this, a research was conducted at a state school in the city of Bauru which was selected for convenience. Participants were randomly selected consisting of 75 students, of whom 21 were third years and 57 were of three classes of fifth year. The instruments used for data collection were: a informative questionnaire to characterize the students in age, grade, favorite subjects and the least liked, among others, an attitude scale, Likert type, to examine the attitudes toward mathematics; a interviews with 11 selected students according to scores on the attitudes and mathematical problems to be solved through the method of thinking aloud. The results showed that the major difficulties encountered by students in solving problems were: to understand the problems, formalizing the reasoning, recognize in the problem the algorithms needed for its resolution, make calculations with decimal numbers, do combinatorics, using the sum of equal portions instead of multiplying, self-confidence and autonomy in what he was doing, and others; participants with positive attitudes towards mathematics showed greater confidence to solve problems as well as a greater understanding on what was required by them, but were not detected significant relation between the attitudes and performance, since it was unfavorable

Validação de uma escala colorida de esforço percebido para adultas jovens e idosas em caminhada na esteira

The perceived exertion has been used for the intensity control and exercise prescription. Among the various scales that estimate the perceived exertion, the Borg’s RPE scale is one of the best known. However, for populations with low levels of schooling or with visual difficulties such as the elderly, the application of these scales becomes more difficult. In previous studies, a color scale of perceived exertion was developed to aim for assistance in application of the scale and interpretation of perceived exertion. This scale showed high correlation with the Borg’s scale and proved to be valid to estimate the perceived exertion. Thereby, the aim of this study was to assess the validity of the color scale of perceived exertion to measure the perceived exertion in adult women of different ages. Participated in the study 12 young adult women with age of 21,7 ± 1,5 years old, and 10 elderly women with age of 60,3 ± 3,5 years old. The participants were submitted to an incremental exercise of treadmill walking with stages of 2 minutes duration. The inicial load was 5,5 km/h and inclination of 6% for young women and 2% for elderly women, both with 2% increments at each stage completed, without changing the speed. Heart rate and oxygen comsuption responses were determined at the 30 finals seconds of each stage. At the 60 finals seconds of each stage participants indicated the perceived exertion for the overall body, for the legs and for the chest, primarily in the color scale and following in the tradicional Borg’s scale. The analysis of variance for repeated measures was used to assess the effect of different loads on the perceived exertion and physiological responses. The correlations betwen physiological variables, color scale and Borg’s scale were analyzed in group and individually. In all analysis the significance...(Complete abstract click electronic access below)

Avaliação da auto-suficiência energética de reatores anaeróbicos aplicados ao tratamento de resíduos de uma cervejaria em escala piloto

This project aimed to analyze the feasibility of the methane yield associated to the anaerobic digestion of brewery residues, checking whether the energetic balance of the system is favorable. The methane yield efficiency was calculated for the parameters of two papers that treated solids with a particle-size <1mm. Theses solids are not degraded in conventional treatment systems. Calculations were based in the reactions of anaerobic degradation of the macromolecules that compose brewery residues, considering the theoretical production and the effective production of methane. The results were 50.44% and 52.86%. Regarding to the energy balance of the anaerobic treatment, we noted the high influence of the selection and operating regime of electrical equipment over the potential energy. The best situation, in which the energetic self-sufficiency was reached, was observed when using the mixer under an intermittent regime (1min/h), without employing the heating recirculator, for the maximum organic loading of 4.0 gVS/L.day (days 248-258). In this case, the system would generate an amount of energy equal to 0.0356 kWh/day, able to overcome the energy required by the equipment in about 6.5 times. Moreover, we also noted the interference of the application of different solid loadings in the reactors, once the application of the higher organic load generated 5 times more energy than the application of the smaller one
