Weber ao pensar a questão da ação pedagógica e da pesquisa cientÃfica o faz de maneira que indica a especificidade da cultura moderna ocidental, onde a instauração do processo de racionalização tornou-se um elemento de importância significativa. Assim, o novo significado adquirido pelo professor quanto pela ciência, na modernidade, está assentado na idéia de que o conhecimento estaria destituÃdo da capacidade de instaurar uma ‘concepção de mundo’ com validade universal. Se aceitamos a idéia de que a ciência e a pedagogia deveria fornecer sentido ao nosso cotidiano, para o nosso bem viver, a descrição de Weber certamente nos contraria. O empreendimento cientÃfico e a ação pedagógica, com o objetivo de buscar a verdade e a compreensão dos fatos, estariam distante da possibilidade de instaurar um conhecimento com validade objetiva universal.

Neste estudo, padrões de tamanho do corpo de Phanocerus clavicornis Sharp, 1882 (Coleoptera: Elmidae: Larainae) foram investigados ao longo de um gradiente de variação de velocidade da corrente em córregos de baixa ordem da Mata Atlântica. Especificamente, buscou-se testar a hipótese de que a distribuição de larvas de P. clavicornis com diferentes tamanhos corpóreos respondem à s variações na velocidade da corrente em córregos. As coletas das larvas foram realizadas com um amostrador de Surber durante dois perÃodos amostrais, definidos pelo regime de chuvas: agosto - estação seca e fevereiro - estação chuvosa. PossÃveis diferenças nas medidas de tamanho do corpo foram testadas através de uma análise de variância (ANOVA). Os resultados daANOVAindicaram para todas as medidas das larvas coletadas nos córregos de primeira ordem (largura da cabeça, largura do protórax e comprimento total do corpo) encontramos diferenças significativas, indicando uma variação morfométrica com as mudanças das condições hidráulicas, onde as larvas menores foram associadas aos perÃodos de maior precipitação. No entanto, em córregos maiores (3a ordem), os eventos de chuva tiveram menor impacto no tamanho dos indivÃduos, com a ocorrência de larvas com diferentes tamanhos. Os resultados deste estudo sugerem que os espaços intersticiais são importantes para a proteção das larvas contra a velocidade da corrente e que as populações de P. clavicornis possuem alta plasticidade, sendo uma caracterÃstica fundamental para a ocupação desta espécie em ambientes instáveis. Esses resultados são importantes para a compreensão da história de vida e caracterÃsticas comportamentais da espécie, que permitem persistir em córregos ao longo de gradiente de perturbação do fluxo.

The objective of this study was to evaluate the possibility of reducing spray concentration and volume of Fluazifop-p-butyl applications on postemergence soybeans, while maintaining weed control and growth selectivity. The study was conducted in the experimental area of the Teaching and Research Farm of FCAV/Unesp - Jaboticabal Campus, during the agricultural season of 1998/99, carried out on a crop of soybean cultivar FT 2009. The experimental setup utilized was a randomized block design with 24 treatments, 20 following a factorial scheme 2 x 2 x 5 and 4 control treatments. The factors examined were: spray volume (100 and 200 L ha-1); reduced spray concentration - 75.2 and 112.8 g of fluazifop-p-butyl/ha (40 and 60% of the recommended concentration, respectively); and application schedule (5 A.M., 9 A.M., 1 P.M., 5 P.M. and 9 P.M.). The controls were applications at the recommended concentration (188.0 g fluazifop-p-butyl/ha), using volumes of 100 and 200 L ha-1, and treatments without weed control and weeds controlled with manual hoeing. The main species of weeds that emerged in the experimental area were: Cenchrus echinatus, comprising 60% of the infested sections; Digitaria horizontalis, 10%, and Eleusine indica, 30%. All fluazifop-p-butyl applications made up to 9 A.M. and from 5 P.M. effectively controlled the three species of weeds and provided a selective growth of soybeans. Therefore, the use of fluazifop-p-butyl can be optimized by reducing both the concentration and the volume of the spray for applications times providing favorable conditions for crop dusting.

Soybeans are an important food due to their functional and nutritional characteristics. However, consumption by western populations is limited by the astringent taste of soybeans and their derivatives which results from the action of lipoxygenase, an enzyme activated during product processing. The aim of this study was to evaluate the effect of gamma irradiation on the chemical composition and specific activity of lipoxygenase in different soybean cultivars. Soybeans were stored in plastic bags and irradiated with doses of 2.5, 5 and 10 kGy. The chemical composition (moisture, protein, lipids, ashes, crude fiber, and carbohydrates) and lipoxygenase specific activity were determined for each sample. Gamma irradiation induced a small increase of protein and lipid content in some soybean cultivars, which did not exceed the highest content of 5% and 26%, respectively, when compared to control. Lipoxygenase specific activity decreased in the three cultivars with increasing gamma irradiation dose. In conclusion, the gamma irradiation doses used are suitable to inactivate part of lipoxygenase while not causing expressive changes in the chemical composition of the cultivars studied.

Alguns vegetais, como a soja (Glycine max L. Merr), despertam interesse, pois fornecem, entre outras substâncias, as isoflavonas, que apresentam importantes propriedades estrogênicas e, também, atuam como antioxidantes, antifúngicos e anticancerÃgenos. A menopausa, causada pela deficiência hormonal, é acompanhada de vários transtornos metabólicos, como perda de massa óssea, fenômenos vasomotores, dislipidemia, resistência insulÃnica, ganho de peso, depressão e aceleração do envelhecimento cutâneo. A terapia de reposição hormonal (TRH) é eficaz, embora possa causar efeitos secundários, como câncer de mama. Nestes casos, a fitoterapia com fitormônios por via cutânea é uma alternativa importante. Dentre as preparações de uso tópico, sistemas emulsionados e géis são muito utilizados, pois favorecem a solubilidade e a estabilidade de fármacos. Para avaliar a estabilidade das formulações, foram consideradas as caracterÃsticas organolépticas (aspecto, cor, odor) e as caracterÃsticas fÃsico-quÃmicas (valor de pH, viscosidade e densidade, etc.), separação de fases e/ou coalescência. Algumas formulações apresentam-se com caracterÃsticas desejáveis e adequadas para a veiculação de isoflavonas presentes em extrato de soja, podendo-se sugeri-las como sistemas adequados e estáveis para sua veiculação pela via dérmica

This essay intends to point to a possible dialogue between Mário de Andrade and Max Jacob, starting from the books of poems Paulicéia desvairada (1922) and O losango cáqui (1926), Le cornet à dés (1916) and Le laboratoire central (1921). Divided into three parts, it investigates the figuration in the two poets of the harlequin’s image, through which both would operate several displacements. One of them, the resumption of a romantic mythology of the artist, as in Baudelaire, and the conscience of his staging character. Other, through the opposition between reason and madness, legitimating a lyrical state as a way to a different perception of the reality. Lastly, through the proposition of an artistic sincerity, moral of work with deep impact over the literary language.

This essay aims at presenting the book Le Cabinet noir of Max Jacob, a book of fictional letters with comments, taking into consideration the moral judgment: right conduct, principles that govern modes of action. This strategy demonstrates the ambiguity of Max Jacob’s project: divided into a certain Catholicism, which he practiced, and avant-garde literature. On the other hand, this study points to the various contradictions such as a certain morality towards the family preservation or friendship, virtues or Christian attitudes and bourgeois conveniences. Finally, it establishes the dimension of desire in face of René Girard’s questionings in the essay Mensonge romantique et vérité romanesque.

This article has a theoretical character and presents some of Weber's ideas, with emphasis on those that can supply elements to reflect on the current state of education, more particularly based on his understanding of modernity. Disenchantment of the world is the key concept in his sociology, and is taken as the basis for a reflection about the meaning that science and the teacher can have today. A classic author, Weber's interpretation of the modern world brings to our consideration a variety of themes that influence markedly the thinking and practice of contemporary culture by its concern with understanding human actions and values. By studying the Western process of rationalization, he initiates debates in science, in ethics and, correspondingly, in education, allowing us to expand our comprehension of the meaning, significance, and role of our actions towards knowledge and teaching. The main object of education is to offer students contents that stimulate the freedom of thought. For that, the teacher needs to adopt a non-partisan ethics in the classroom, presenting contents unbiased by her/his political opinions and, if failing to do so, having the honesty to explain what she/he is doing. It is therefore of the utmost importance that the teacher should keep a neutral position, so that in and out of the classroom the students may reflect and question what they see, experiment and decide upon. Only then the conduct of the teacher will be consistent with the process of rationalization of our culture.

Based on the lack of information regarding the morphology of marsh deer, this work aims to describe some morphological aspects of the gastric chamber in this species, collaborating with future investigations, mainly related to rational handling in this cervid. This work aimed to describe the morphology of the gastric chamber of the marsh deer, characterizing the external and internal macroscopical details and the microscopical architecture of these structures by light microscopy. Macroscopically, the marsh deer stomach is formed by the rumen, reticulum, omasum and abomasum similar to the domestic ruminants. Microscopically, rumen and abomasum are similar to the domestic ruminants. The reticulum and the omasum, however, present specific characteristics such as keratin on the top of the reticulum, small epithelial projections and omasum folds covered with discrete papillae.
