Liver samples of Oreochromis niloticus cultivated in floating net cages were fixed for histological and ultrastructural studies with the objective of describing the hepatic parenchymal structure and the intrahepatic exocrine pancreatic tissue. Anatomically, the liver showed only two hepatic lobes. Histological analysis demonstrated that the hepatocytes were spread out as anastomotic cords, arranged in two cellular layers and surrounded by sinusoids. The intrahepatic exocrine pancreatic tissue exhibited an acinar arrangement and was diffused in the hepatic parenchyma. Structural analysis showed that the hepatocytes had a rounded nucleus and a rough endoplasmic reticulum with a parallel disposition to the nuclear membrane. The exocrine pancreatic cells showed secretion granules at the apical portion and the rough endoplasmic reticulum was concentrically distributed

Se evidenciaron sólo 2 lóbubos hepáticos. El análisis histológico demostró que los hepatocitos se encontraban organizados en forma de cordones anastomosados, dispuestos en dos capas celulares y cercados por sinusoides. El tejido pancreático exocrino intrahepático se encontró difuso en el parénquima hepático y se destacó por su organización acinar. El análisis ultraestructural demostró que los hepatocitos presentaban núcleos redondos y el retículo endoplasmático rugoso estaba dispuesto paralelamente a la membrana nuclear. Las células pancreáticas exocrinas presentaban gránulos de secreción localizados en la porción apical y el retículo endoplasmático rugoso estaba organizado de manera concéntrica

Modelos são representações da realidade que têm se revelado úteis para o avanço do conhecimento em inúmeras áreas. Este artigo busca apresentar um modelo de inovação tecnológica em que esse fenômeno seja concebido como sendo: a) sistêmico; b) multinível; c) organizacional, d) multideterminado; e) passível de mensuração; f) de intervenção. A literatura sobre modelos de inovação apresenta propostas em que dois elementos estão sempre presentes: a) o processo de P&D, em suas diversas etapas; b) determinantes dessas etapas, ou fatores originados nos contextos macro, meso ou micro do processo de inovação. A literatura sobre gestão tecnológica apresenta modelos de gestão, enfatizando variáveis relativas à gestão de portfólio e gestão de pesquisa em rede, como as mais relevantes para os modelos de gestão de última geração. A proposta apresentada neste trabalho integra essas duas literaturas, procurando enfatizar a relevância de variáveis de gestão tecnológica como determinantes importantes, ao longo do processo de inovação tecnológica. O artigo conclui com uma discussão de áreas beneficiadas com a utilização do modelo. Made available in DSpace on 2011-04-09T12:31:10Z (GMT).

O desempenho de uma válvula reguladora de pressão, fabricada pela Fabrimar, Modelo Exact-20-Ref. RP-3-20-3/4"FF, utilizada em pivô central, foi avaliado em laboratório, conforme as normas ISO (1993). Este trabalho foi desenvolvido no Laboratório de Irrigação do Departamento de Engenharia Rural, ESALQ/USP, utilizando-se reguladores de pressão novos e com diferentes tempos de emprego no campo. As curvas de desempenho das válvulas novas satisfizeram as condições exigidas pela norma, caracterizando o regulador como do tipo A, para as velocidades de referência de 0,5 m s-1 (vazão de 0,57 m³ h-1) até 4,0 m s-1 (vazão de 4,50 m³ h-1) e várias pressões de entrada, sendo também elaborado um modelo estatístico para a pressão de saída do regulador novo, com uma vazão e uma pressão de entrada. Foram coletadas, de diversos sistemas tipo pivô central e de diferentes vãos, válvulas reguladoras de pressão do mesmo modelo, que possuíam tempos de uso de 2000, 2500, 6000, 8500, 9000 e 10000 h e, também, com diferentes qualidades de água utilizadas. Os ensaios seguiram os mesmos padrões dos novos, realizando-se uma análise estatística dos dados. Apesar dos desgastes provocados pela água de má qualidade e dos vazamentos apresentados, o desempenho hidráulico das válvulas com tempo de uso até 6000 h, não diferiu do desempenho das novas, para pressões de entrada até 826,3 kPa e velocidades de referência até 2,5 m s-1. O desempenho dos reguladores de pressão com tempos de uso iguais ou superiores a 8500 h, não se manteve semelhante ao do regulador novo, especialmente para pressões de entrada superiores a 481,7 kPa.

O planejamento institucional, na sua dimensão mais ampla, é a ferramenta mais poderosa disponível aos administradores, para aumentar a preponderância dos fatores objetivos na gestão. É aplicado nas suas dimensões estratégica, tática ou operativa e usa o conhecimento, baseado em informação sistematizada, para administrar com maior peso em fatores objetivos uma instituição. Sistematizar informação é organizá-la de forma coerente, sistêmica e racional, para que flua nos diversos escalões gerenciais de uma instituição, apoiando o processo de tomada de decisão. Isto implica, em estruturar sistemas de informação. Como a informação pode cobrir uma imensa gama de atividades, uma forma de delimitar tais sistemas de informação é vinculá-los à atividade de planejamento, e estruturá-los como sistemas de informação gerencial. A Embrapa desenvolveu o seu Sistema de Informação Gerencial, o SIGER, com o propósito de integrar, em um único sistema, o seu planejamento de P&D. Este trabalho apresenta o desenho conceitual do sistema. São discutidas e descritas as relações conceituais do SIGER com as funções de planejamento, acompanhamento e avaliação da empresa, as etapas metodológicas para seu desenho e suas características e atributos principais e a validação do SIGER, a metodologia adotada e os principais resultados obtidos, os quais foram utilizados para a finalização do sistema Made available in DSpace on 2018-03-28T00:30:51Z (GMT).

O uso de plantas medicinais tem aumentado bastante na população mundial. O objetivo desta pesquisa é avaliar os efeitos do extrato aquoso das folhas da Hyptis pectinata, popularmente conhecida como "sambacaitá" ou "canudinho", sobre a regeneração hepática após hepatectomia parcial de 70%. Foram utilizados 24 ratos, divididos em 4 grupos: grupo OS, em que se realizou operação simulada e aplicação oral de água destilada por 4 dias; grupo OSD200, também submetido à laparotomia com manipulação do fígado e aplicação de 200 mg de extrato/Kg de animal durante o mesmo período; grupo HP, hepatectomizado a 70% após 4 dias de aplicação por via oral de água destilada; e grupo HPD200, hepatectomizado a 70% após 4 dias de administração de 200 mg extrato/Kg de animal. Foram dosadas fosfatase alcalina, bilirrubina total e as aminotransferases e estudou-se o estado III da função mitocondrial. O grupo OSD200, quando comparado ao OS, apresentou redução significativa da fosfatase alcalina. O grupo HPD200, em comparação ao HP, teve redução estatisticamente significativa no nível da AST e do estado III da função mitocondrial. The use of medicinal plants has strongly increased by the world population. The objetive of this study is to assess the effects of the aqueous extract of Hyptis pectinata leaves, popularly known as "sambacaitá" or "canudinho", on liver regeneration after 70% partial hepatectomy. Twenty four rats were divided into 4 groups: group OS, submitted to sham operation and oral administration of distilled water during 4 days; group OSD200, also submitted to sham operation and ingestion of 200 mg of extract/Kg of animal for the same period of time; group HP, which underwent 70% hepatectomy after 4 days of distilled water administration; and group HPD200, which underwent 70% hepatectomy after 4 days of oral administration of 200 mg of extract/Kg of animal. Alkaline phosphatase, total bilirubin and the serum level of aminotransferases were measured and state III of mitochondrial respiratory activity was assessed. Group OSD200, when compared to OS, presented significant decrease of alcaline fosfatase. Group HPD200, when compared to HP, showed statistically significant decrease of AST level and state III respiratory process.

For the 1493 animals involved in this experiment (657 males and 836 females) biometrical data were obtained (weight, length and tympanum diameter) and developmental stages of gonads were determined. Female sizes at first maturation were 10,33 cm and 109,78 g and for males it was around 8,09 cm; all males above 45 g were already in the maturation process. The relationship between tympanum diameter and body length (RTC) was considered a good index for male maturation. UNESP, Botucatu, SP, Brazil UNESP, Botucatu, SP, Brazil
