OBJETIVO: O objetivo deste estudo foi analisar as características cinemáticas, cinéticas e eletromiográficas do andar de adultos jovens em piso fixo sem colete e com suporte parcial de peso (SPP) de 0, 10, 20 e 30% do peso corporal. MÉTODO: Oito jovens com idade média de 22,2 anos foram filmados andando sobre uma passarela que continha uma plataforma de força na região central para registro das componentes da força de reação do solo. Marcadores refletivos foram posicionados nos principais pontos anatômicos dos membros inferiores para registro dos dados cinemáticos, e eletrodos de superfície foram afixados nos músculos tibial anterior e gastrocnêmio medial para registro da atividade elétrica muscular. RESULTADOS: Diferenças significantes entre as cinco condições experimentais foram constatadas nas variáveis espaço-temporal, nos ângulos máximos e mínimos da coxa, joelho e tornozelo e nas amplitudes das componentes horizontal ântero-posterior e vertical da força de reação do solo. de forma geral, as maiores mudanças ocorreram na condição de SPP de 30% do peso corporal. CONCLUSÃO: É importante considerar as compensações que ocorrem no padrão do andar com SPP no planejamento das intervenções terapêuticas. Ainda, para melhor definir a utilização dos sistemas de suspensão de peso na reabilitação, estudos futuros precisam ser realizados para verificar o comportamento do andar em populações com alteração de movimento em piso fixo.

The aim of this work is to present the principal properties and applications of supporting electrolytes (SE) to students, teachers and researchers interested in electrode processes. Different aspects are discussed including the importance of SE in maintaining constant the activity coefficients and the diffusion coefficients and reducing the transport number of electroactive species. Its effect on the electrochemical kinetic parameters is also presented.

Apresentam-se os resultados de uma pesquisa sobre a construção de conceitos de Física Moderna e sobre a natureza da Ciência com o apoio da hipermídia, que envolveu a produção e avaliação de um software educacional. A proposta didática fundamentou-se na Teoria da Aprendizagem de Ausubel, em orientações para a implementação de sistemas hipermídia educacionais e em abordagens derivadas da pesquisa em Ensino de Ciências, dentre as quais o enfoque Ciência-Tecnologia-Sociedade, ponderações quanto à importância pedagógica da História e Filosofia da Ciência e considerações sobre a inserção de Física Moderna no Ensino Médio. O programa foi avaliado por pesquisadores de Ensino de Física e licenciandos de Física e, após a incorporação de algumas sugestões realizadas, foi testado por estudantes do terceiro ano do Ensino Médio de uma escola pública. Obtiveram-se indícios de que o uso do computador foi fator de motivação dos estudantes; a diversidade de elementos de mídia auxiliou-os a fixar a atenção sobre o conteúdo e favoreceu a visualização e interpretação dos fenômenos, facilitando ainda o raciocínio; o hipertexto estruturado em conformidade com princípios ausubelianos contribuiu para a percepção da relação entre os conceitos e ajudou no desenvolvimento de subsunçores para apoiar a aprendizagem subseqüente. Constatou-se que a proposta didática avaliada favoreceu a evolução das concepções da maior parte dos estudantes quanto ao conceito de equivalência massa-energia e suas implicações; às relações entre Ciência, Tecnologia e Sociedade, incluindo aspectos ambientais e políticos; ao papel da Ética no desenvolvimento e aplicação dos conhecimentos científicos; ao progresso da Ciência ao longo do tempo.

Objective: evaluating the adequacy, prescription and energy supply of enteral nutrition therapy in hospitalized patients. Methods: was performed a retrospective survey of the evolution of TNE protocol of 59 patients hospitalized in a general hospital in Marília / SP / BR. Data collected included gender, age, clinical diagnosis, anthropometric and dietary data related to the prescribed dietary formula, route and method of administration of the enteral nutrition, the daily volume prescribed and administered, the daily amount of energy required and offered in the diet, as well as possible complications. Body mass index (BMI), triceps skinfold (TSF) and arm muscle circumference (AMC) were used to establish the nutritional status of the patients. The adequacy of ENT was done according to the daily energy requirement compared to the average energy received during the daily use of ENT. Results: The average found to the BMI was 21.4 kg/m 2, and no differences were found comparing male and female. The data for TSF and AMC were different between genders (p<0.05) and suggest a more severe muscle mass in relation to adipose tissue. The averaged to the energy requirements was 1642 kcal/day but the average of energy prescribed was 1045 kcal/day and the amount offered was 1035 kcal/day. There was a significant difference between the necessity and the supplied energy offered through enteral nutrition (p=0.00) as well between the energy required and prescribed (p =0.00), both were shorter than the necessity. There was no significant difference (p>0.05) in energy supply, volume of enteral nutrition prescribed and administered among eutrophic, underweight or overweight patients. Conclusion: The results of this study indicate that the prescription and energy supply were not based on the needs of these patients, causing a significant energy deficit, which can lead to worsening of the nutritional status of the same. In hospitalized patients in use of ENT, the energy requirement must be made by a qualified professional within the multidisciplinary team, based on the needs of each patient.

The quality of life of caregivers is a concern because it directly affects the quality of life of individuals dependent on such care. This study aimed to analyze and compare the quality of life in health of caregivers of people with special needs who attend a rehabilitation facility. Ninety caregivers of people with special needs who attend a rehabilitation facility participated in this study. For data collection two instruments were used: a questionnaire to determine the profile of the caregiver and the person with special needs and the WHOQOL-Bref questionnaire to measure quality of life. The results were significant only between the caregiver's quality of life in the physical domain and age of the person with special needs, indicating that the older a person with special needs, the more difficult and arduous is the act of caring. The result can indicate guidelines for caring for families of people with disabilities.

Invertase from Saccharomyces cerevisiae was immobilized on agarose beads, activated with various groups (glyoxyl, MANAE or glutaraldehyde), and on some commercial epoxy supports (Eupergit and Sepabeads). Very active and stable invertase derivatives were produced by the adsorption of the enzyme on MANAE-agarose, MANAE-agarose treated with glutaraldhyde and glutaraldehyde-agarose supports. At pH 5.0, these derivatives retained full activity after 24h at 40°C and 50 °C. When assayed at 40°C and 50°C, with the pH adjusted to 7.0, the invertase-MANAE-agarose derivative treated with glutaraldehyde retained 80% of the initial activity. Recovered activities of the derivatives produced with MANAE, MANAE treated with glutaraldehyde and glutaraldehyde alone were 73.5%, 44.4% and 36.8%, respectively. These three preparations were successfully employed to produce glucose and fructose in 3 cycles of sucrose hydrolysis.

The objective of this work was to evaluate the magnetic susceptibility efficiency for estimating the support capacity of areas for vinasse application. Two hundred forty-one soil samples were collected from a 380-ha area, on which soil chemical properties, clay content, and magnetic susceptibility were determined. Vinasse requirement was calculated for each sample. Data were subjected to descriptive statistical analysis, and regression models were developed between magnetic susceptibility and the other evaluated attributes. The analysis of data spatial dependence was performed using geostatistics. Kriging maps and cross variograms were built in order to investigate the spatial correlation between soil magnetic susceptibility and studied attributes. Based on the map of vinasse requirement, on the soil classes, and on the kriging map, calculations were done for average vinasse dose and average soil support capacity, weighted by the area. Magnetic susceptibility has significant linear spatial correlation with recommended vinasse doses and soil support capacity for the application of this effluent, and it can be used as a pedotransfer function for indirect quantification of soil support capacity.
