Storage moduli, loss moduli and damping factor of GaAs and Ga1-xMnxAs thin films using DMA 2980

The spin injector part of spintronic FET and diodes suffers from fatigue due to rising heat on the depletion layer. In this study the stiffness of Ga1-xMnxAs spin injector in terms of storage modulus with respect to a varying temperature, 45 degrees C <= T <= 70 degrees C was determined. It was observed that the storage modulus for MDLs (Manganese Doping Levels) of 0%, 1% and 10% decreased with increase in temperature while that with MDLs of 20% and 50% increase with increase in temperature. MDLs of 20% and 50% appear not to allow for damping but MDLs <= 20% allow damping at temperature range of 45 degrees C <= T <= 70 degrees C. The magnitude of storage moduli of GaAs is smaller than that for ferromagnetic Ga1-xMnxAs systems. The loss moduli for GaAs were found to reduce with increase in temperature. Its magnitude of reducing gradient is smaller than Ga1-xMnxAs systems. The two temperature extremes show a general reduction in loss moduli for different MDLs at the study temperature range. From damping factor analysis, damping factors for ferromagnetic Ga1-xMnxAs was found to increase with decrease in MDLs contrary to GaAs which recorded the largest damping factor at 45 degrees C <= T <= 70 degrees C Hence, MDL of 20% shows little damping followed by 50% while MDL of 0% has the most damping in an increasing trend with temperature.

El gobierno de las megalópolis, el caso de Brasil, São Paulo: gestión metropolitana, descentralización y participación como desafíos simultáneos

The government of a megalopolis, such as São Paulo, shows singular challenges that do not exist in less complex urban contexts. Being a city of a country with a recent industrialized economy, with an income (functional and geographical) highly concentrated, that has resumed the democracy for only one quarter of a century, this megacity lives with its own political and organizational assignments, due to the contradictory character of the political behavior of its habitants/ voters and of the traditionalist nature of populism and patronage in the relationship between the rulers and the ruled and between the Executive and Legislative powers at the local level. In such context, the difficulties to prosecute the assignments of the metropolitan organization, the decentralization and the institutionalization of citizen participatory channels in the governance and administrative activities are huge. The centrifuge forces (of the decentralization of the local government, through subprefectures), the centripetal forces ( of the metropolitan organization process) and the diffuse forces (of the claiming popular participation) act simultaneously over the deciding processes, in São Paulo, receiving, still, state and national political influences, since the city is a very significant historically producer of political and electoral capital. The analysis of the recent experience of the creation of the subprefectures and the representative counsels (fixed in the Municipality Organic Law of 1990) and the attempt to implement the participatory budgeting, in two occasions (1989-1992 and 2001-2004), reveal some of the social and political reasons that make difficult the establishment of a solidly democratic governance and of a more efficient public administration in the metropolitan area of São Paulo.

Artes orientais de movimentos: alternativas às terapias do campo da saúde. uma possibilidade de investigação para a psicologia do esporte. um exemplo de pesquisa fenomenológica

This research analyzes the discourse of teachers of ancient oriental arts, namely: Yoga, Tai Chi Chuan, Kung Fu, Lian Gong, Qwan Ki Do, reveals the meaning that subjects have about what are the benefits to health of those already considered practical alternatives conventional treatment of health. The research uses the phenomenological method specifically the method of the phenomenon. The method first provides a pre-reflection on the oriental arts, exposing not systematically, some curiosities changing between aspects of oriental arts: historical, main teaching methods, styles, the character of struggle, why are linked to health, the benefits of their practices, movements, philosophy, concepts, ways of acting, the roots, the basics. In this article the pre-reflection does not appear to meet the standards of Congress page limit. Rather concentrate on the next step of the research and present the phenomenon situated in the experience of those who have experienced it in the case of the five arts teachers mentioned above. The method performs individual analysis or ideographic analysis of the five discourses of teachers from each oriental art and then conducts the general or nomothetic. The result is presented an analysis of generalities, convergence, divergence and individuality of meanings expressed by the subject, to finally develop a discussion of these data and weave a synthesis. The analyzes reveal that Eastern practices currently as some of these five analyzed here, those involving aspects of struggle and concentration are excellent allied health development and well-being. Understanding the philosophical aspect is inherent in the practice of the movements, although the character of the struggle, which they transmit through knowledge of their origins and roots is the current thinking routine that generates a life philosophy of selfhelp, self-enabling and tranquility preparation to overcome the tensions, disputes, everyday challenges. The speeches also reveal that the psychophysical aspects of diseases are real, because the practices of movements and the physical drilling of these oriental arts have enabled visible improvements in health by working the mental and the physical in an integrated manner. Masters must have all the knowledge to better meet today's society, preserving these cultures, passing them through the generations.

Meios de comunicação social de massa e a agressividade do espectador de futebol

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.

O jogo sob uma investigação psicanalítica

To Freud the group of the psychic activity has for purpose the search of pleasure and escape to the displeasure, and of that drift that the aspects associated to memories of unpleasant experiences have for tendency the removal of level of conscience. The unconscious repeats in subject, in way of being and through where he sees the world. That repetition also shows in practice of game. This study leaned on in analysis of Freudian work to play. Because, independent of sphere in that it is acting, the activity of the game is accomplished, predominantly, under an atmosphere predominantly pleased. The game can propitiate situation so that it happens the sublimation of drive forces, making possible occurrence, in an acceptable way socially, contributing to accomplishment of satisfaction. Like this, this study had as objective contemplates, starting from the reading of passages of Freudian work, on desire and the pleasure to play. For the elaboration of that text pertinent bibliographical revision was accomplished to the game, in relationship with psychoanalysis starting from Freud and other authors.
