Relatórios de Pesquisa em Engenharia de Produ??o , 2009,
Abstract: No Brasil durante as últimas duas décadas medidas para melhorar a qualidade dofornecimento de energia elétrica oferecido pelas concessionárias tem sido tomadas eintensificadas pelo órg o regulador. Neste trabalho se realizará um estudo para avaliar aprodutividade das concessionárias distribuidoras de energia elétrica, baseado em doisindicadores de qualidade que medem a freqüência e a dura o das interrup es dofornecimento de energia (FEC e DEC). A técnica utilizada para esta análise será a Avalia oProbabilística de Produtividades, uma metodologia que se baseia em medi es deprobabilidades de atingir a fronteira de eficiência ou de pior desempenho. Este estudo seconcentrará em identificar as concessionárias menos eficientes. As distribui es Uniforme ePareto ser o utilizadas para efetuar os cálculos de produtividade e posteriormente seusresultados ser o comparados. Ao final será calculado o índice de Malmquist que irá buscaravaliar a evolu o do ano de 2006 para 2007 do desempenho de cada concessionária emrela o ao conjunto.

Abstract: Twenty eight dogs and 11 cats from S o Paulo State Municipalities (Araraquara, Cosmorama, Jaboticabal, Pontal, Sert ozinho and Taiuva cities) were submeeted to nechropsy. The animals, males and females, no defined race, with different ages and naturally infected by parasites were transported to the CPPAR – Centro de Pesquisas em Sanidade Animal – UNESP. After a five days period, in which the animals have recived water and ration “ ad libitum”, they were killed under normal ethic anesthetic scientific research procedures. A total of 1010 parasites were identified in the dogs, with the following occurrence and infection range: Toxocara canis (71,43% and 0 to 58%); Ancylostoma caninum (76,14% and 0 to 77), Ancylostoma braziliense (57,14% and 0 to 117); Dipylidium caninum (42,86% and 0 to 73) and Physaloptera praeputialis (3,57% and 0 to 1). Among the 750 helminths identified in the felidae the occurrence and infection range were: A.caninum (100% and 3 to 275), D. caninum (54,54% and 0 to 33), Hydatigera taeniformis (45,45% and 0 to 45), P. praeputialis (54,54% and 0 to 20) and Platynosomum fastosum (27,27% and 0 to 5). Foram submetidos à necropsia 28 c es e 11 gatos, provenientes dos canis municipais de Araraquara, Cosmorama, Jaboticabal, Pontal, Sert ozinho e Taiúva, Estado de S o Paulo. Os animais, machos ou fêmeas, sem ra a definida, de diferentes faixas etárias e naturalmente infectados por parasitos, foram alocados no “Setor de C es e Gatos” do CPPAR – Centro de Pesquisas em Sanidade Animal – UNESP, durante cinco dias (período de adapta o), recebendo água e ra o “ad libitum”. O sacrifício dos animais foi efetuado de acordo com os procedimentos anestésicos recomendados pelas normas éticas utilizadas na pesquisa científica. Nos c es, 1010 helmintos foram diagnosticados. A ocorrência e amplitude de infec o foram: Toxocara canis (71,43% e 0 – 58), Ancylostoma caninum (67,86% e 0 – 77), Ancylostoma braziliense (57,14% e 0 – 117), Dipylidium caninum (42,86% e 0 – 73) e Physaloptera praeputialis (3,57% e 0 – 1). Dos 750 helmintos diagnosticados nos felinos, a distribui o de acordo com a ocorrência e amplitude de infec o foi: A.caninum (100% e 3 – 275), D. caninum (54,54% e 0 – 33), Hydatigera taeniformis (45,45% e 0 – 45), P. praeputialis (54,54% e 0 – 20) e Platynosomum fastosum (27,27% e 0 – 5).

Costa Gustavo Carneiro da,Sim?es Alexandre Zirpoli,Gasparotto Gisele,Zaghette Maria Aparecida
Materials Research , 2003,
Abstract: Thin films of BBT were deposited on silicate and Pt/Ti /SiO2 (111) substrates by spin- coating from the polymeric precursor method (Pechini process). The obtained films were characterized by optical microscopy, X-ray diffraction and atomic force microscopy. The influence of viscosity on the morphology of BBT thin films as well as the influence of temperature on crystallization, morphology and properties of BBTare discussed. Surface roughness and crystallization of these films are strongly dependent on the annealing conditions.

Abstract: the application of silicon (si) is beneficial to plants. however, there are doubts about the efficiency of foliar application. the objective of this work was to evaluate the effect of foliar application of si, in the form of stabilized silicic acid (a newly developed source), on the nutrition and productivity of crops of soybean, common bean and peanut. the experimental design for each crop was of randomized blocks with fourteen replications. the treatments were foliar application of si at a dosage of 2l ha-1 of silamol ? (0.8% soluble si as a stabilised concentrate of silicic acid) and a control (without the application of si). the si was divided into four applications. foliar application increased the si content, providing an increase in the number of pods and a higher seed yield in all three crops. the increase was around 14; 15 and 9.6%, respectively, for the soybean, common bean and peanut.

Abstract: A aplica o de silício (Si) é benéfica às plantas. Porém, existem dúvidas sobre a eficiência do seu fornecimento via foliar. Objetivou-se com este trabalho avaliar o efeito da aplica o de Si via foliar, na forma de ácido silícico estabilizado (fonte recém-desenvolvida), na nutri o e na produtividade das culturas da soja, feij o e amendoim. O delineamento experimental para cada cultura foi em blocos casualizados, com quatorze repeti es. Os tratamentos foram: controle (sem aplica o de Si) e aplica o de Si via foliar, na dose de 2 L ha-1 do produto Silamol (0,8% de Si solúvel como um concentrado estabilizado de ácido silícico). A dose de Si foi parcelada em quatro aplica es. A aplica o via foliar elevou os teores de Si, proporcionando aumento do número de vagens e da produtividade de gr os das três culturas. O incremento foi da ordem de 14; 15 e 9,6%, respectivamente, para as culturas da soja, feij o e amendoim. The application of silicon (Si) is beneficial to plants.

Abstract: the objective of this work was to evaluate the influence of two organic cultivation systems on the growth, phenology, nutrition, and productivity of coffee cultivars, as well as on soil chemical characteristics. six coffee cultivars were evaluated under both a monoculture system under full sun, and an intercropped system with banana and erythrina verna plants for shading. the experimental design adopted was the randomized blocks with four replicates. the shading reduced the growth rate of cultivars only during the first 15 months of cultivation. after three years of cultivation, the shading reduced the plant diameter, the number of branches and the number of nodes; increased the leaf area and grain size; reduced soil k content and increased n and mg contents in coffee plant leaves. in the first harvesting (march 2004), the average yield of the cultivars was smaller in the shading system showing that this treatment delayed grain maturity. in the second harvesting (june 2004), there were differences among cultivars, but not between cropping systems. yield total average for the two harvestings was the same in the two systems. the cultivars tupi, icatu, and obat? are more promising in shading system.
