This work was developed to evalute the physical and mechanical properties of a panel of three particle layers from the test specification of NBR 14810-3 (2006), using wood of Eucalyptus sp. and Eucalyptus saligna and Eucalyptus urograndis bark. The mechanical properties were evaluated to obtain the bending modulus of rupture (MOR) and modulus of elasticity (MOE) and Internal bond. The physical properties were obtained thickness sweeling, water absorption, moisture content and board density. Were evaluated four different compositions of panels containing 5, 10, 15 and 20% in the inner layer of bark. The results were compared with the Brazilian standard NBR 14810-2 (2006) and also with studies in the literature. The panels produced were adequate to all the optimal values suggested by the standard only in the composition with 5% skin in the inner layer. The other treatments showed satisfactory results in all tests except for moisture content

The style of life in the cities deprives the man of the contact with nature. As a way to escape from the turbulent reality of the urban system, the urban planning provides areas that allow the contact between man and nature like botanical gardens, parks, leafy squares, etc. These places, through specific analysis, are also called green areas. Thus, the main purpose of this research is to outline and analyze, through geoprocessing techniques, green areas of Americana, São Paulo considering them as indicators of urban environmental quality. This evaluation will be based on the methodology adapted by Bargos (2010) where products of remote sensing were used (aerial photos and satellite images) and it will be also based on field work and calculation of the amount of green areas. The software ESRI ArcGIS® will be used to create thematic maps connected with city’s green areas. Based on the results achieved in this study, it’s expected to contribute to the government of the city of Americana in order to provide benefits of analysis for decision makers in the context of urban planning aiming an improvement in the urban environmental quality, thus benefiting its entire population

Previous studies show that in areas contaminated by fuel spill (NAPL- non-aqueous phase liquids), from operational activities, transport and storage, it was possible to observe a significant decrease of ²²²Rn (radon) gas concentration in the soil, even a non-uniform distribution of this gas in top soil, even with a geological situation was practically homogeneous. These anomalies may be associated with the preference partitioning of radon in NAPLs. This work consists of applying ²²²Rn as an indicator for locating subsurface contamination by NAPLs in an area of the city of Rio Claro (SP) where, according to the “Survey of Contaminated and Rehabilitated Areas in the State of São Paulo (Environmental Sanitation and Technology Company - CETESB), there was, in the year 2007, groundwater contamination from leaks of liquid fuels. The challenges of this research are: Promulgate the use of a new tool with greater efficiency in obtaining results, in addition to generate less impact in half and have less expenditure; disseminate scientific culture promoting greater integration of C&T (culture & technology) between universities and businesses. The emanometric technique to estimate the location, number and interfacial area of NAPL in saturated and non-saturated zone, has the advantage of locating and determining plumes of free phase even when the amount of VOC's (Volatile Organic Compounds) that reaches the surface is low or non-existent. In addition, the measurement techniques ²²²Rn are quite developed. The results obtained show that, similar to the other studies, the 222Rn soil gas presents an anomalous behavior in the area bounded by NAPL plume, being possible to note a significant deficit in the concentration of the gas in spots where the saturation by NAPLs is still critical. Therefore it is concluded that this tool is really promising, but we must be careful to evaluate the initial conditions of the area, as well as the type of...

The aim of this work is to make a qualitatively and ecologically evaluation of a compact cogeneration system that operates with synthesis gas obtained from a gasifier. Using the Eucalyptus Biomass as fuel, that passes through a wood gasifier (Drowndraft type) and supply the internal combustion engine. The compact cogeneration system is composed of two heat exchangers, an energy generator connected to an internal combustion engine and an absorption refrigeration system. The complete system is installed in the laboratory from the Energy Department at the University of Guaratinguetá. By the analysis related to the First and Second Thermodynamic Laws applied in this system, was possible to identify the mass flows in each point, energetic efficiency, irreversibility and exergetic efficiency. The components that have the biggest irreversibilities are the gasifier, followed by the internal combustion engine, which should be focused in future improvements. The system efficiency in energetic basis is 51,84% and in exergetic basis is 22,78%. Using the ecologic efficiency methodology was possible to identify the emissions rates, the pollution indicator associated to the combustion of the synthesis gas in the internal combustion engine. The ecologic efficiency considering the energectic analysis is 91,73%, while considering the exergetic analysis, 83,65%. It is concluded that the use of the synthesis gas in a compact cogeneration system is viable from the technical and ecological point of view, making possible to generate energy for isolated communities and promoting the decentralized electricity generation

O presente estudo, que foi desenvolvido considerando os dados de quatro municípios do Estado de São Paulo (São Carlos, Araraquara, Matão e Gavião Peixoto), teve como propósito definir um Indicador de Desenvolvimento Regional e teve os seguintes itens pesquisados: consumo energia elétrica residencial e industrial, população, valor adicionado total e o número de empregos gerados. Desses itens foram utilizados o valor adicionado e o número de empregos gerados para definir um indicador de desenvolvimento regional a fim de detectar o desenvolvimento dos municípios estudados, utilização de mão de obra qualificada e a geração de riquezas obtidas e distribuída entre esses municípios. A construção desse Indicador teve como base os dados dos municípios paulistas do período de 2001 a 2007. Após a mensuração do indicador de desenvolvimento regional foram extraídos e analisados os seguintes dados: análise do crescimento desses indicadores que levam ao desenvolvimento dos municípios vizinhos e a formação de um agrupamento produtivo local (cluster). Esses dados também foram utilizados numa análise estatística de regressão para estimar previsão de crescimento desses municípios em função do setor aeronáutico que está se instalando na região estudada. Foi observado também que no período estudado houve um crescimento de consumo de energia elétrica industrial e residencial, propiciando aos seus habitantes uma melhor qualidade de vida, com melhores salários e benefícios comuns. Esse indicador é altamente favorável, pois evidencia que a tendência de agrupamento de empresas no mesmo setor, contribui para o desenvolvimento da sociedade onde está inserida, incentiva o crescimento dos municípios e fomentando as atividades. No período de 2001 a 2005, os municípios de Araraquara, Gavião Peixoto e São Carlos tiveram um crescimento no indicador, de maneira estável... (Resumo completo, clicar acesso eletrônico abaixo)

O joelho, por suas características anatômicas e freqüente instabilidade e exposição as lesões tem o quadríceps como importante músculo a ser desenvolvido quanto ao seu trofismo e força. Composto de quatro porções distintas estas podem gerar diferentes vetores de força que podem ter relações diretas com o recrutamento de unidades motoras. O posicionamento articular, a conseqüente modificação do comprimento muscular e a intensidade da contração podem influenciar o desenvolvimento da força do quadríceps. Dentre as contrações relacionadas ao maior recrutamento de unidades motoras com o intuito do desenvolvimento de força está a contração isométrica. Dentre as contrações musculares, as isométricas têm sido frequentemente indicadas para aumentar a força e estabilidade articular em sessões de treinamento e reabilitação. Pelo exposto, o objetivo do estudo foi analisar os músculos vasto medial (VM) e vasto lateral (VL) por meio da eletromiografia de superfície durante 15s de contração isométrica a 20%, 30%, 40% e 50% da contração isométrica voluntária máxima – CIVM com o joelho a 90 graus. Foram utilizados eletrodos de superfície bipolar de Ag/AgCl, posicionados nos músculos VM e VL, um módulo de aquisição de sinais biológicos (Lynx) calibrado com ganho de 1000vezes, filtro de passa alta de 20Hz e de passa baixa de 500Hz. Uma célula de carga foi acoplada perpendicularmente à cadeira de teste especialmente desenvolvida para o estudo e utilizado uma indicador digital para retorno visual. Na análise estatística utilizou-se teste de Friedman e teste de Wilcoxon, e adotou-se nível de significância de p<0,05. Verificou-se que os músculos VM e VL foram semelhantes entre si, e entre as cargas, houve diferença significante entre as cargas de 20% e 40%, 20% e 50%, e 30% e 50% para ambos os músculos, com maior atividade nas cargas de 40% e 50% CVM...
