This study aims to recognize the Surface Design as specialty hybrid and clarify the relationship between surface and design through projetual creative act and technical. The study shows that there projetual hybridity in the design of the Surface Design and the same occurs in two distinct stages: the creative phase , where the inherent design specialties together for their training , and executive process in which the diversity of technical information and construction procedures to assist the integration of design with other productive areas . Identify the products presented its projected surface condition , based on concepts checked the state of the art Surface Design was an action that enabled the verification of functional, aesthetic and symbolic object concepts . To evaluate this condition are presented six case studies to verify the levels of cooperation and implementation of the specialties of Design in objects that are highlighted by presenting different surfaces. Among the products are: DKR chair, bench Pai João, bench R540, Híbridos table, Facetas table and bench Xique-xique.

Recent research seeking to elucidate the possible effects of different types of physical training on the morphological adaptations of skeletal muscle. Although it is relatively easy to study the effects of exercise training in humans, such research becomes limited due to the invasive nature of the biopsies and the risk inherent in the use of human subjects. Thus, the application of animal models of training has been considered an appropriate strategy for the study of muscular adaptations in response to exercise. Objective: This study used a rodent model to determine the possible effects of aerobic and strength training on the CSA of fibers of the plantaris muscle. Methods: 24 male Wistar rats (80 to 120 days, 250 to 400 g) were randomly divided into 3 groups: aerobic training (TA, n = 8), strength training (ST, n = 8) and control (CO, n = 8). The animals in groups TA and TF were subjected to 8 weeks of training, while the animals of group C remained without any stimulus from start to finish the training period. At the end of the experiment, the animals were sacrificed and right plantar muscles dissected and removed. For morphological and morphometric analysis of muscle fibers was performed staining was performed H.E. Results: There was no significant difference in initial body weight between experimental groups. After 8 weeks of training, the TA group showed a significant reduction in final body weight, compared to CO and TF groups. With respect to the CSA of fibers of the plantaris muscle, no significant difference between the groups CO and TA. On the other hand, the strength training promoted a significant increase in AST of the group TF in compared with the groups CO and TA. Conclusion: Strength training used in this study promoted an increase in CSA of fibers of the plantaris muscle. On the other hand, animals submitted to aerobic training showed no changes in the CSA of the fibers, however, there was reduction in PC animals. The data strongly suggest the use of animal model of strength training used in this study as an appropriate strategy for studying the hypertrophic response of skeletal muscle.

O conhecimento sobre a turbidez atmosférica é de grande importância para áreas de climatologia, monitoramento de poluição e estudos da atenuação da radiação solar em condições de céu limpo. Neste trabalho o modelo de turbidez atmosférica de Linke (TL), modificado por Li e Lam é descrito e utilizado na estimativa da turbidez atmosférica e radiação solar direta na incidência (Ib). Os dados de Ib na incidência e radiação global utilizados são do período de 1996 a 2003. Os resultados mostram que TL apresenta sazonalidade em função do clima local variando entre 3,10±0,72 (maio) e 3,93±0,91(setembro), com média anual igual a 3,51±0,25. Na estimativa de Ib, ocorreu sub/superestimativa (MBE), espalhamento (RMSE) e ajustamento (d), respectivamente, em: janeiro: -4,38%; 13,87%; 0,83 e junho: 2,00%; 8,98%; 0,94. Com base nos valores dos três indicativos estatísticos, o melhor desempenho do modelo foi obtido nos meses de céu sem nuvens e baixa poluição.

This work explores the suitability of the Lagrange interpolating polynomial as a tool to estimate and correct solar databases. From the knowledge of the irradiance distribution over a day, a portion of it was removed for applying Lagrange interpolation polynomial. After generation of the estimates by interpolation, the assessment was made by MBE and RMSE statistical indicators. The application of Lagrange interpolating generated the following results: underestimation of 0.27% (MBE = -1.83 W/m2) and scattering of 0.51% (RMSE = 3.48 W/m2).

Evaluated statistical equations estimates (based on radiometric fractions) of the hourly diffuse radiation incident on inclined surfaces for the North to 12.85, 22.85 and 32.85°, the climate and geographical conditions of Botucatu, SP. The database was generated from April/1998 to December/2007, with measures in the three tilted surfaces in different periods, but concomitant to the horizontal plane. In the validation of the equations were used indicative statistics MBE (mean absolute error), RMSE (square root mean square error) and index adjustment (d) for three inclinations and conditions of sky coverage. The increased angle of inclination of the surface led to increased scattering of hourly values for the coefficient of atmospheric transmissivity of diffuse radiation for inclined and horizontal surfaces. Estimates of diffuse radiation on the basis of hourly tilted horizontal global radiation occur for quadratic polynomial models, which adjust K'Dβ maximum values of between 0.14 and 0.30 for winter and summer when KTH varies between 0.40 and 0.66, indicating that energy, the highest values of diffuse radiation occur in partly cloudy sky conditions and / or partially open. The increase in atmospheric transmissivity decreases the performance of annual and monthly equations at all inclinations.

O objetivo do trabalho é desenvolver um sistema informático de digitalização e processamento de actinogramas baseado em técnicas de Processamento de Imagens Digitais e comparar com o sistema tradicional de medidas. Os actinogramas foram fornecidos pela Estação Meteorológica de Botucatu (FCA/UNESP). As análises preliminares indicam um desempenho satisfatório do software proposto, gerando medidas na mesma ordem de grandeza do método de referência para partição diária. O software proposto pertence a um projeto que se encontra ainda em andamento, onde rotinas de técnicas diversas continuam sendo implementadas no reconhecimento da curva de interesse para melhorar a qualidade do processamento das informações gráficas dos actinogramas. Os actinogramas estão em fase de digitalização para que o software possa ser testado com uma base de dados mais consistente, onde poderão ser identificados tendências temporais dos dados resultantes da aplicação das técnicas de Processamento de Imagens Digitais no monitoramento da radiação solar por actinógrafos.

A interferência causada pelas plantas daninhas pode reduzir em até 80% a produtividade de grãos do feijão quando não manejadas de forma correta. Portanto, a decisão sobre o momento de controlá-las é um dos principais aspectos do manejo integrado. Nesse sentido, objetivou-se com este trabalho determinar o período anterior à interferência das plantas daninhas (PAI) em cultivares de feijão com diferentes tipos de hábitos de crescimento. Adotou-se o delineamento experimental de blocos casualizados com quatro repetições. Os tratamentos experimentais foram constituídos de dez períodos de convivência da cultura com as plantas daninhas: 0-7, 0-14, 0-21, 0-28, 0-35, 0-42, 0-49, 0-56, 0-97 (colheita) dias após a emergência (DAE) e mais uma testemunha sem convívio com as plantas daninhas. O PAI foi determinado por meio de distintas abordagens: o nível arbitrário de 5% de perda na produtividade, o nível de tolerância (NT) e o de dano no rendimento econômico (PADRE). O PAI obtido foi diferente em todas as abordagens, e os feijoeiros de crescimento indeterminado tipo II apresentaram os menores tempos de convivência.

OBJECTIVE: To estimate the prevalence of lead poisoning in children and to identify associated factors, as well as possible local sources of contamination. METHODS: A cross-sectional prevalence study conducted in 2006 with a random sample of 97 children age zero to five years from a neighborhood in Porto Alegre, Southern Brazil. Blood lead levels were measured and a questionnaire administered to collect information on sociodemographics, recycling and dwelling. A preliminary environmental evaluation was carried out with direct analysis of soil and indirect analysis of air pollution with bioindicators to identify possible sources of contamination. To analyze lead concentrations from the different collection sites, for each type of material studied, ANOVA was performed with a Brown-Forsythe adjustment for heteroscedasticity and with Dunnett's T3 procedure for multiple comparisons of unequal variances. RESULTS: Blood lead levels >= 10.0 mu g/dL was found in 16.5% of children. Recycling of waste at home, low father's education level, and increased age of children were associated with increase blood lead levels. High lead levels were found in soil, and there was little indication of lead air pollution. CONCLUSIONS: A high prevalence of lead poisoning was identified, and the potential sources of contamination in this community appear related to waste recylcing activities. Studies should be conducted with other populations of Brazilian children and evaluate potential sources of local and general contamination, to accurately characterize this issue in Brazil.
