The use of rats in studies that seek to monitor the effects of physical exercise is fairly common, even in works that make use of overload. However, the correct determination of the training load is critical to success of studies. Thus, with the objective of verifying the correlation of total body mass of the rats with their respective strength, and the correlation of the 1RM test with test repetitions, 40 rats, 90 days old and weighing average 0,49 pounds underwent a program of adaptation to the water and then were subjected to tests to determine the maximal and submaximal loads. After measuring the total body mass and maximal and submaximal strenght, it was possible to observe directly proportional relationship between maximum strenght and total body mass of 0.97 (P ≤ 0.01), being the maximum muscle strength equivalent to 109% of the total body mass. Between muscle strength and mass submaximal muscle strength was also found direct correlation between the variables, allowing to conclude that the submaximal strength test and total body mass are effective tools in determining the training load of rats.

This study is to provide parameters from theoretical and exploratory research in the creation and institutionalization of information science to establish a link with Information Literacy. Approaches are presented in which contributions allow us to understand the relationships and kinds of science in general and their applicability to the population studied, since these theories have a big relationship with the deepening of the area and their social, cultural and economic relationships. We hope to contribute with selective reference to assist the understanding of the issues arising from information science and the knowledge generated by its researchers. This requires developing new skills of access and use of information, providing an interaction between information literacy and knowledge building in Information Science.

The mass media have a decisive function in formation of opinion and conduct of population. Among those, the television is a vehicle with great power of spread of information. The objective this study is to analyze the influence of media on occurrences regarding the aggressiveness some participants involved in event soccer, while spectators. The subject's attitude is determined by predominant factors, among them the influences of social and cultural way in that lives, as well as, of the education and sporting influences that it affects. The problem of violence in the sport, in the case of soccer, it cannot be addressed for total responsibility of media. However, collaboration is indispensable, for aspect positive and/or negative, depending on the interest in subject. The models of behavior in television could influence the spectator's behavior for a learning process, for example, the use of the language. Therefore, it is indispensable to rethink the roads of television, their ethical conducts and to discuss the philosophical sense of the crisis. Because, to reject the mass media is to deny the reality and social transformations. The extent of the Physical education, above all in the school, is a fundamental space for the teacher to intermediate the meaning of the sport, in this case, the soccer-spectacle, in social context and their relationships with the media, enlarging the process civilization, so much inside as out of field.

In spite of education it was not main element of Freud's work, in elapsing of work he considered it in chapter denominated “Education Interest of the psychoanalysis” (1913). The objective is to intend to the teacher to consider the importance of psychoanalytic focus in pedagogic extent, demonstrating her contribution for understanding of the students' formative processes. Consequently, to contemplate, starting from the Freudian work, on transfer concept in that relationship introducing intervention forms in the teaching process and learning. We adopted the revision of literature related to the psychoanalytic aspect that it approaches the education, in interface with school physical education. In other words, we specifically looked for aspects on the theme of transfer in the interface of psychoanalysis with pedagogy. Also, part of the Freudian work was used regarding the theme approached in analytical indexes. Since then, we detected that the observed authors affirm that between teachers and students relationship transferencial exists. Therefore, the selection of contents sends the educators to organize and systematize as it will be worked in curriculum and transmitted to the students, since it should go to the encounter of students’ expectations, doing with that school physical education has sense and meaning. Therefore, it is important the physical education teacher, in school, to analyze that when working with the human being there are just no effects of work on content or about the use of correct teaching methodology, but, also the actions transferenciais that are present in learning process.

Aluminum Alloys are widely used as structural materials in the aerospace industry due to low weight, high mechanical strength and enduring corrosion resistance. Their resistance to corrosion is attributed to the rapidly formed stable oxide film (Al2O3) which spontaneously forms itself on the surface of the material. However, in the presence of aggressive ions, such as halide, Aluminum Alloys are subject to a localized process of corrosion. The electrochemical behavior of 7081-T73511 and 7050-T7451 Aluminum Alloys employed in the aerospace industry was investigated using a 0.6 M NaCl solution under the conditions of a controlled mass transport employing a rotating disk electrode. The theoretical limiting current density was determined by the Kouteki-Levich equation. The results confirmed that the inter-metallic Al7Cu2Fe acts as preferential cathode generating the galvanic coupling and the dissolution of the Aluminummatrix around it.
