Composição florística de um trecho da mata ciliar do Córrego dos Antunes município de Jaú - SP

A mata ciliar é de extrema importância para a boa qualidade da água assim como evita a erosão do solo das margens dos corpos d´água. No entanto, grande parte das matas ciliares estão em processo de degradação, sendo sua restauração ou recomposição uma emergência. Para isso torna-se necessário saber qual é a composição florística da mata ciliar a ser recuperada. O presente trabalho analisa a composição florística de um trecho da mata ciliar do córrego dos Antunes, situado no município de Jau/SP, a qual está muito degradada. Foram feitas coletas quinzenais entre os meses de abril a setembro de 2008, nas quais foram coletadas amostras (parte reprodutivas ou ramos com folhas) das espécies arbóreas com lenho e DAP igual ou superior a 5 cm. Foram encontradas espécies exóticas, de mata de brejo, xerófitas e espécies que de fato ocorrem em matas ciliares e entre essas ultimas espécies que não foram relatadas em matas ciliares da região.

Poesia visual e poética postal

Ce travail cherche montrer quelques caractéristiques de la Poésie Visuel, expresion artistique qui melange le langage verbal et le langage visuel à tel point qu´on ne peut pas afirmer une classification appuyée sur les genres traditionnels. Aprés une curte presentation des chemins et des points polémiques de cette esthétique, on analyse comme exemple deux compositions sorties de le grand réseau de communication de l´Art Postal qui est né les années soixante et survit aujourd´hui avec intensité. L´Art Postal a une structure fondé sur la simultanéité de l´information que ressamble à la forme de la poésie visuel. Cettes compositions contemporaines sont confrontées à la tradition du poème visuel qui commence peut-être à l´époque des premiers écrits de hiéroglyphe. Elles sont analysées, donc, dans son originalité. A partir des analyses realisées dans le but de révéler les significations, on arrive à la question proposé par Wilcon Joia Pereira : la nécessité de se comprendre d´une façon nouvelle les expériences esthétiques oú les mots deviennent des images

Atualidades no tratamento da laminite em equinos

Laminitis is still a major cause of lameness in horses, causing damage to many interested in it. It has been long studied, but there are several points that are not yet fully understood. Doubts about its pathogenesis end up extending at the treatments. Just as there are several theories that attempt to explain the mechanisms of its development, also appear treatments that are sometimes contradictory and inconsistent. Mostly times, laminitis is a consequence of another disease process that occurs systemically in the body. Among them are the main grain overload and processes that cause the animal to the table of endotoxemia, strangled colic, metritis with retained placenta and pleuropneumonia. The proposed treatments include the use of anti-inflammatory drugs, cryotherapy, use of vasodilators and correction of Starling forces, and other measures to support the frog. The stall should be bedded deeply with sand or other material that provides support to the frog

Avaliação dos efeitos dos inseticidas malation e fipronil sobre a viabilidade e regeneração de girardia tigrina (Platyhelminthe, tricladida)

In this study were carried out toxicity tests and the evaluation of sub lethal effects of the insecticides malathion and fipronil, over the test system of Girardia tigrina, using for these analyses a great variety of methods. For evaluation of the lethal concentrations of the products, adult planarians were exposed to several different concentrations. All the tests were carried out in duplicate, maintained on the shelter of the light, on a temperature 24-26ºC and they had the duration of 96h, with observations at each 24h. The results were statically valued by the tests U of Mann- Whitney, Spearman-Karber, ANOVA and Pearson correlation. The effects over the system-test, in the different tested concentrations, varied in accordance with the time of exposition. The EC50 given by the test of Spearman-Karber was of 12,5mg/L for malathion and 13,4mg/L for fipronil. The evaluation of sub lethal effects was composed by analyses of the potential of regeneration; histological, for tissue damage evaluation; d; and the “comet assay”, for DNA damage detection. The specimens split up and exposed to the insecticides demonstrated, between other effects, retardation in development of the regenerative blastema. The histological evaluation has shown that exposed planarians to lower concentrations of the insecticides cause more significant damage against the tissues and some specific cell types. Through the comet assay, significant damages were noticed in the DNA in all the treatments, when compared with the control group. Such damages may result in reproduction and immunity alterations, which reduce the competitive efficiency and, consequently, the survival chances of these organisms.

Efeito da prática do futebol no desempenho em agilidade, velocidade e coordenação de meninos na categoria dentinho ou sub 11 (10 e 11 anos de idade)

In Brazil, the practice of Soccer is encouraged very early. It is common remark that parents enroll their sons into soccer schools, promoting the involvement of these children in formal practice. However, there are not many studies that assess the effects of this practice in the physical capacities of children. Thus, the question that guides this study is: children who practice soccer systematically present better development of physical, especially agility, coordination and speed? The objective of this study was to compare the performance in velocity tests, agility and coordination of boys of 10 and 11 years, category dentinho or Sub-11, practitioners of soccer in schools and non practicing. The study included male children, born in 1997 and 1998, formed two groups: group of practitioners of soccer and group of non practicing. To belong to the group of practitioners, the child was regularly engaged for at least 1 year, with 1 hour daily and 2 to 3 times per week. The participants of the group of non practicing were not involved in regular practice of soccer and were paired in weight and stature with participants of the group of practitioners of soccer. Each participant was individually assessed in neutral environment and without foreign interference. For the assessment of the agility, was utilized the (shuttle run) test. The race test 30 meters stopped was employed for the assessment of the speed. The test of fiddling between the cones was employed to measure the coordination. The time spent to perform 1 attempt to each test was used for the comparison between groups. These data were treated, initially, by descriptive statistics (mean and standard deviation) and, subsequently, were compared by means of Anova, for independent samples. The significance level was maintained at 5%. Through analysis of the results the conclusion is that the regular practice ...(Complete abstract click electronic access below)

This study brings the definition of physical parameters used in the dosimetry of electron beam, describes the tests for quality control of linear accelerator with a electrons beam, as well the activities realized in the Radiotherapy Division, of Hospital de Clinicas, in the Universidade Estadual of Campinas, in the Clinac 2100C machine

Clínica psicomotora

A proposta de uma clínica psicomotora visa ser um espaço que busca criar condições para que a criança se desenvolva em todos os aspectos necessários ao seu bom desenvolvimento físico, motor, cognitivo, emocional e intelectual. A impossibilidade de ação corporal provocada pela ocorrência de uma dificuldade relacionada à psicomotricidade interfere negativamente no desenvolvimento infantil, impedindo a criança de vivenciar situações próprias do mundo infantil. O desenvolvimento de uma criança depende, de forma significativa, do movimento e da sua relação com o mundo externo, pois é através da expressão corporal, por meio de seus movimentos que o ser humano recebe e transmite informações e manifestações de seus vários sistemas biológicos.

Um estudo sobre a evolução recente da agroindústria em Cuba

Este trabalho visa a análise da evolução e desempenho da agroindústria cubana, com enfoque no setor canavieiro no passado recente. A cana foi responsável por formar as bases econômicas da ilha na época colonial, através de acordos com os Estados Unidos, que perduraram até os embargos econômicos sofridos por este país na década de 50. A partir destas sanções, é evidente que mudanças na estrura ecônomica do país viriam a ocorrer. Era preciso que os alimentos antes importados dos EUA continuassem a ser acessíveis à população bem como o açúcar continuasse a gerar dividendos para o país. Para isso Cuba em meio à Revolução Socialista e da aliança com a extinta URSS, que comprava o açúcar cubano à preços artificiais enquanto o país moldava mudanças estruturais na agroindústria canavieira para atender às necessidades básicas. A derrocada da URSS no final da década de 1980, fez com que a artificialidade do mercado de açúcar entrasse em colapso, ocasionando em um grande declínio na agroindústria, e na tentiva do Governo Socialista em reverter este cenário
