Considering that alcohol has been identified, in the literature, as an evident risk factor for osteoporosis development, inducing loss of bone mass, the aim of this study was to evaluate the effect of the alcohol on the femur of male and female rats. For this purpose, 35 male and 35 female rats, divided into seven groups of five animals per genera were included. The groups were: control group that received food and water as much as they wished; alcohol group in the concentrations of 10, 20 and 30% and the isocalorie: groups corresponding to the concentration of alcohol. After 8 weeks, the animals were sacrificed and evaluated regarding to the body weight and nutritional conditions. Unilateral femurs were removed and analyzed in relation to the length, width, and thickness of the bone cortical, trabeculae percentage and optical density. Data obtained were analyzed by ANOVA (Tukey; p<0.05). Regarding to the weight, loss of weight was observed in the animals of the group alcohol 20% among females and 30% among the males. In relation to the nutritional conditions, the females with the dosages of 10, 20 and 30% of alcohol swallowed a mean of 25, 39 and 53% of Kcall and the males 22, 36 and 45 Kcal Jday coming from the alcohol. Alcohol reduced the length of the femur only in the group MG6. Mesio-distal width was higher in the group FG6 although the antero-posterior width was not modified. The cortical thickness among males and females was not altered however the percentage of trabeculae bone was reduced among females alcohol 30% and among males with the three alcoholic concentrations. Optical density was reduced in the concentration of 30% among the males and females. Under the experimental conditions, it could be concluded that the effect of alcohol was more evident among the males and in the trabeculae bone, and that the alcoholic concentration of 30% was the most harmful for the bone tissue, ....

The German philosopher G.W.F. Hegel (1770-1831) had as one of his thesis in the doctorate the affirmation that philosophy can only be properly taken as a system. He intends with that to point out the identity between thinking and being. This is, for Hegel, the task of philosophy, i. e., to bring together all that was set apart. This position can be recognized in all his works and it is tried here to exemplify it in The Philosophy of Right and in special in the section dedicated to the abstract right. This one is the first moment of the text in question that begins with the statement of the dignity of the person confirmed in the property. The following moments make evident that the formal ones are also results. It becomes clear in this way that the all the moments create together an ongoing organization, disorganization and reorganization. This process reveals the relation as a constitutive element of thinking and being exemplified in the abstract right. Each moment overcomes the preceding one and comes out as a much more complex one. In the case of the abstract right what appears is the realization of a free subject in all that he does as the making of himself.

This article presents elements that make up the quality of education in the age group of zero to five years, offered by institutions of Early Childhood Education in Brazil, based on research results disseminated in theses and dissertations that focus on this theme. It was used as the methodological procedure outlined mapping Brazilian literature of academic research related to the Post-Graduate Education, which focus on the issue in the period between 1996 and 2012. The results of the study provide insights on funding, teacher training, family, quality of care in the school systems, institutional assessment, perceptions of quality and educational practices that allow discuss the quality of early childhood education offered in Brazilian institutions. Moreover, considering that not convenient to take the concept of quality of early childhood education as universal as this is linked to the context, the conceptions about children and their education.
