The writings of Hegel’s youth have suffered a great influence of Kant’s Philosophy which he considered the philosophy of his time. Despite such feature that can be traced in young Hegel’s writings, many signs of a growing separation from Kant’s thinking can also be noticed. In this way this paper aims at indicating Hegel’s early criticisms of Kant. The chosen text deals with the official religion and the folk religion. For Hegel the dichotomic dualism reason – senses translated into the excluding distinction soul – body implies the impoverishment of religion poor as well as of its transforming role.

The Hegelian philosophy is presented as a progress in relation to other philosophies and it offers to take in itself all the other demonstrations. Thereby, Hegel intends to carry out his philosophical effort towards the establishment of a philosophical system. It is a comprehension recognized and exposed by Hegel in his doctoral thesis, i.e., that philosophy only becomes possible as a system. In this sense, the treatment dispensed to each one of his works necessarily evokes a relationship with all other. An work taken in isolation gets the feeling that something else should be presented, however, every work written by Hegel also contemplates a relation with his other works. In this sense, the objective here is to considerate Hegel’s Philosophy of Law in his philosophical system seeking to explicit its specific place, as well as its transit among the works of the thinker as a whole. The Philosophy of Law finds its particular moment in the ambit of the objective spirit or during the subjective spirit’s effectuation. However, it is assumed here the perspective that the Philosophy of Law represents, as the objective spirit does, a moment of mediation as well as a there-being whereby the absolute spirit’s effectuation would happen. Furthermore, Hegel’s Philosophy represents the presentation of what he considers as extremely important in philosophy, that is precisely, the need to sublate the separation between man and the world. It is not enough for Hegel, the affirmation of the being and the thinking in itself, but it is required to confirm them in their being other that will be evinced being itself. Thus, Philosophy is given as a reconstruction or as the factual knowledge as a science ceasing to be so only love of learning. This means in other words that philosophy deals with the world, in the world and for the world being much more than a speech to the world to be the talk of the world itself. If philosophy is the owl of Minerva who always arrives late, she does it for the reasons of the other to be recognized.

Among numerous studies about the selective collection of solid waste and cooperatives of recyclable materials, this research aims to contribute with the study of these problems from the geographic space. As the world population increases, the issue of solid waste becomes increasingly worrying, due to new consumption patterns that create larger amounts of waste, especially in the urban centers. The recycling appears to be the best solution for this problem since most materials that are currently sent to landfills would become raw material for new products. The Triage Centers performs an important role in this process because they are responsible for sorting, packing and selling the materials arising from the selective collect, so it is necessary to analyze the places where these steps are performed. This study intend to examine the location and distribution of these enterprises in the city of São Paulo in order to provide support for the mitigation of impacts, both environmental and social, from their location, as well as provide support for the expansion of selective collection program in the city. The choice for studying this area was due to the curiosity of investigating the inefficiency of the recycling program in the city of São Paulo, which currently recycles about 1% of all household solid waste collected. Therefore, from a historical survey of the city's recycling programs, technical visits, interviews with responsible agencies and also analysis of the Triage Center's frameworks based on the guidelines from the municipal legislation, it will be evaluated the problems faced by the program for its expansion

This paper aims to survey data to analyze the productive capacity of a machining process of rolling bearings by methods-time measurement, in order to identify its bottlenecks and propose improvements in the system. The production times at the company are not known, the method of separation of operations and identification of its activities and the timing of production times and setup become points of departure for this paper. The results from this method of analysis provide clarity in identifying system weaknesses and by them it was possible to carry out the proposals for improvement in some process steps. The implementation of the improvements was not performed, but with the goals of this work was made possible to raise relevant information of the analyzed system

As formigas cortadeiras, pertencentes aos gêneros Atta e Acromyrmex, possuem esse nome pelo hábito que têm de cortar as folhas das plantas. Por este motivo, elas causam danos econômicos, principalmente em áreas de cultura agrícola. Para realizar o controle dessas pragas, existem inúmeros métodos; porém, os únicos que apresentam resultados satisfatórios são os que utilizam inseticidas tradicionais. O controle químico pode gerar efeitos maléficos ao ambiente, à fauna e à população humana. É por isso que há uma grande procura por métodos alternativos, utilizando produtos que tenham grande especificidade e sejam passíveis de rápida degradação, sendo, portanto, menos danosos ao ambiente. Uma destas alternativas é a utilização de produtos naturais presentes nos vegetais superiores, que podem constituir novas fontes de material com ação tóxica para estes insetos praga. Este trabalho teve por objetivo avaliar a toxicidade das plantas Magonia pubescens e Duguetia lanceolata para operárias de Atta sexdens rubropilosa. Para os testes, as formigas foram divididas em lotes de 50 operárias, distribuídas em 5 placas para cada tratamento e mantidas em B.O.D. durante os 25 dias do experimento. Nos bioensaios de ingestão, os extratos provenientes das plantas foram incorporados em dieta artificial e testados durante 25 dias. No bioensaio tópico, as substâncias eram colocadas no pronoto das formigas e era oferecida dieta pura em todos os dias do experimento. Após os testes, os dados foram transferidos para o software Prisma 3.0, para a confecção de curvas de sobrevivência e para a realização das análises estatísticas. Apesar de Magonia pubescens apresentar um bom resultado, não foi possível continuar com os testes, pois a alta polaridade dos extratos impossibilitava a separação das substâncias...

O gênero Astronium, pertencente à família Anacardiaceae, é composto por cerca de 35 espécies, sendo típico das regiões norte e nordeste do Brasil. De acordo com a literatura, apenas a espécie Astronium urundeuva foi investigada sob o ponto de vista farmacológico, sendo detectada atividades antiulcerogênica , antiinflamatória e efeitos no trânsito gastrintestinal . Nas espécies A. graveolens e A. fraxinifolium foram avaliados somente os óleos essenciais, sendo que em A. graveolens um desses compostos voláteis mostrou atividade repelente a insetos. Desta forma, percebe-se que a investigação desse importante gênero vegetal ainda é incipiente. Estudos preliminares com o extrato em acetato de etila das folhas de A. graveolens mostraram grande concentração de compostos fenólicos, como derivados de ácido gálico e flavonoides, os quais estão descritos na literatura em geral como substâncias antioxidantes em potencial. As propriedades antioxidantes de diversas substâncias são alvo de interesse nos dias de hoje principalmente por estarem relacionadas à terapêutica de doenças degenerativas. Com o objetivo de dar continuidade aos estudos das espécies citadas, foram utilizadas neste trabalho técnicas de cromatografia como análise por cromatografia líquida de alta eficiência para o estudo do perfil químico de Astronium graveolens, separação e identificação de metabólitos secundários. Baseado na literatura e na comparação com padrões, os espectros de ultravioleta observados, indicaram que os extratos em acetato de etila da espécie em estudo são compostos por substâncias derivadas do ácido gálico, derivadas do ácido cafeoilquínico e também por flavonóides. A substância Ag1 foi identificada a partir de experimentos de comparação por CLAE usando banco de padrões, após verificação de similaridade entre tempo de retenção e máximo de absorção...

Dogs are becoming more and more a part of family life, but the relationship between man and dog is not always healthy. Many dogs are abandoned and illtreated due to their behavioral problems. Among the main behavioral disturbances reported in dogs, there are the separation anxiety, compulsive disorder, aggression and fear. Despite the necessity, there is a paucity of skilled professionals in this field and a difficulty in finding articles on the subject. This paper describes the ways to assess the behavioral problems and address in an objective way some of the major behavioral problems presented by dogs, its etiology and treatment

The tanning wastes are characterized to be significant sources of pollution in the hydrosphere when non adjusted or disposed adequated form. That happens because this industry type uses the chromium to tan hides, and this element is present in discharges concentrations in final wastes, characterizing this waste type as dangerous, according to the Associação Brasileira de Normas Técnicas, através da Norma Brasileira 10.004 de 2004. Due to this, the research proposes a form to reduction chromium of the tanning wastes through the process of adsorption. For that were used mining-wastes of Corumbataí Formation clays, material commonly used in the production of ceramic products in Rio Claro (SP). They were accomplished laboratory essays that involved the preparation of different clays pulps and subsequent mixture of these with the tanning wastes, maintaining them under different mixing times and adsorption contacts. After the separation of the mixtures, the leached were chemically analyzed and it was seen the efficiency of chromium reduction and your relationship with the variation of different times of contact clays/wastes and different grain sizes used in the pulps preparation.
