This study aimed the geological characterization at scale 1:50.000 of an area belonging to the southern sector of the Brasilia Belt, located in the western portion of the Passos Nappe, near the town of Cássia, MG. In this region, outcrops rock types belonging to Araxá Group, composed of metasediments associated with metavolcanics which form a tectonometamorphic terrain of great importance for understanding the geological evolution of southeast and midwest regions of Brazil. With the development of work was possible to group the rocks in 10 lithostratigraphic units and had been identified 3 different zones of metamorphism generated during the peak metamorphism. The structural pattern of the area shows that the main foliation has average dip 30 ° NW and mineral lineation parallel to the stretching direction with 290 °. Still, we can conf irm that this inverse gradient metamorphic rocks of the Passos Nappe, described by several authors. Also, were seen lithotypes of economic interest, some already in exploitation, such as clay and sand, and other mineral commodities, which are occurring and can be used: quartz, quartzite, garnet, kyanite, rutile and zircon.

The mining research is a complex activity, which should preferably involve the combination of direct and indirect techniques of geological research. The increasing demand for base metals in domestic and international markets provide the revaluation of mineral occurrences, which can be converted into deposits and mines. This paper presents the results of the application of geophysical methods of electric resistivity and induced polarization in main foliation parallel to the arrangement of the area, in a deposit of oxides and hydroxides in massive and disseminated ores, docked in gneisses and quartzites, located in the municipality of Itapira, in the North of the State of São Paulo in Brazil. Inversion models indicate the predominance of high cargabilidade that partially coincide with low resistivity values. Integration of geophysical data made possible the drafting of sections of electric walking with cross-checking distance x depth, for detailing your target. The integrated analysis of geophysical and geological structural data leads to the conclusion that the primary mining suffers structural control with the regional foliation in ores

This study has the objective of presenting a new suggestion to the public relations professional into the Brazilian fashion business, seeing that, besides promising and little explored, presents social-economic conditions that allow the profession actuation. For this, it has been deeply analyzed the social character of fashion history e its development parallel to the society historical and economic transformations, basing, then, the study of fashion history in Brazil. To understand contemporaneity and the relations which interlace on it, there were used two analyzes about nowadays social order, liquid pos-modernity, from Bauman; and the hypermodernity, from Lipovetsky. In this context, it‟s approached new ways of relating with marks and with products which, since their consumption, are prepared to posterior discard. In the accelerated scenario of marks and consumption, the human relations, more liquids and tenuous, create the urgent possibility of action from on communication professional, who knows to identify the consumers desires and foresee their needs, rendering the tenuous laces stronger and the relationships more solid. This is when the profession of public relations presents itself as a new proposal to create experiences and to tight the loose laces on the consumption era

The increase in the elderly population has been significant in recent years in Brazil, with the growth in the relative share of the population aged 65 or more, which was 4.8% in 1991 and reaching 7.4% in 2010, this occurred mainly due to the growth of the adult population, especially also for the increased participation of the elderly population (IBGE, 2010). This situation has challenges of political, social, economic and mainly related to the health of the elderly population. The practice of physical activity, especially gymnastics, are offered to the population as a means of improving the health and quality of life (BURINI, 2005; MATSUDO, 2002; MAZO, 2003). From this context, this course conclusion work aims to report gymnastics programs developed in Denmark for the elderly population and reflect on the differences and similarities with the Brazilian fitness programs for seniors presented in the literature. The method used to develop this work of completion will review the literature on physical activity programs for seniors and, in particular, gymnastics, developed in Brazil and published in national Physical Education, minimum classification B2 (CAPES, 2012 ). Parallel to this, the description of fitness programs directed to older people in Denmark, as an account of personal experience of five months in Folk High School Gymnastik og Idraetshojskolen Viborg / Denmark. In the results of the study, were founded eight projects of physical activity of elderly people in the articles. Compared with the Brazilian projects studied, and observed Danish, they differ primarily the goals of the programs, which directly influences the activities conducted training. The frequency is similar but the Danish culture of physical exercise, makes Denmark people want to practice more activities off-hours programs. Another equally important aspect that emerges...

In this paper, we will show the types of Lorentz transformations, from the most described in books, special Lorentz transformation that relates two inertial systems whose relative velocities are directed along an axis of the respective bases systems. However, we will see a peculiarity that goes unnoticed in this transformation, although they have reported in many books a parallel between the transformation inertial systems, due to the fact that the speed is parallel to an axis, it is actually a semi-parallel processing. The next transformation that we will see is one in which a system moves with a relative speed that has arbitrary direction with respect to a given system, we will show that this transformation may be appointed as non-rotational Lorentz transformation. Before obtain, the later type of transformation, the rotational Lorentz transformation, which is the interface between Special Relativity and General Relativity, we will describe the systems to be rotated, not just inertial systems, show what the characteristics are that define the non-rotational and rotational transformations. The in last topic of this chapter we will also show how the idea of Thoma’s theorythat uses this transformation to create what he defines as the proper coordinate axes of the particleused to obtain the factor 1/2 electron spin. In the last chapter we show how the Lorentz invariants are obtained, quantities measures that are also in different Lorentz reference, with the focus on mass that has erroneously been described in many books, that varies according to the agreement reference system

The process of sanding wood is little known and industries use it in a practical way without having studied their best conditions before. There are few studies involving this type of machining. On this basis, this paper studied the effects of varying moisture content of the wood surface quality after the sanding process. It was used a sanding machine with flat horizontal cut parallel to the fibers, using: 02 different species (Pinus elliottii and Corymbia citriodora); 01 sanding abrasive (aluminum oxide) and 03 different particle size abrasives ( P80 , P100 and P120 ) . Initially, the pieces were acclimatized ( 2 ± 7% , 12% and 17% ± 2 ± 2 ) and subsequently passed by the sanding process, and therefore, the surface roughness was analyzed. For each condition, were performed 06 repetitions totaling 54 trials for each species. We analyzed the effects of wood moisture by capturing the power sanding, rougheness, acoustic emission and maximum temperature during the sanding process. The variation of moisture content produced changes in the surface quality of the finished parts, and these changes were more marked in Pinus than Corymbia. During the sanding process of the specimens with 7 % and 12 % humidity, there was a lower noise emission, power consumption and heating surface. When checking the roughness of these parts after this process, it was observed that the surface quality of them were superior in the parts sanded containing 17 % moisture

The difficulties related to physics teaching are related to methodology, that hinder learning, because some physical concepts beyond the common sense of most students. Just as poor training of some physics instructors in teaching is pedagogical difficulties. And also factors of infrastructure, heterogeneity in students' previous training etc.. It is proposed aim of this work to use reflection of teaching practice as a methodology. Practiced in a private school, mostly state and, in high school in Rio Claro. The method consists of preparing a daily pedagogical practice in parallel to the development of teaching, for analysis and identification of factors that result in improving the teaching of physics and physics teacher qualification

The concept of physical education emerged in the XIX century through the European gymnastic methods, initially for the purpose of asserting the sovereignty of the nationality of countries, by means of exaltation of patriotism of the masses and the physical preparation for military wars. Nowadays, the cult of the ideal body has changed, becoming the unceasing desire within each society, according to its characteristics of established standards, most of the time denying the genetic determinations of each ethnicity. This social phenomenon has generated openness and encouragement to the fitness market on the rise, eager in supporting the aspirations of the cult of the body”, representing the huge seek of the idea of a healthy body and an aesthetic appearance acceptable in today's society. Parallel to this, the Body Awareness Gymnastics, also known as Technical or Complementary Practices, were introduced in Brazil in the 70s, presenting as main themes the body awareness, the mind-body relationship, and against the ideals of body training. According to authors, the pioneering technique of the movements of alternative practices in Brazil was Antiginástica of Thérèse Bertherat. Therefore, this study aims to harmonize the complementary body practices of the physical education area through literature review of published works by the author Thérèse Bertherat, entitled The body has its reasons, The body communication system, Stations of the body, The Tiger´s Den and When the body is consent. The work also includes the contribution of a particular reading of the researcher, from the experiences of the practices carried out in order to enrich the reporting work through their records, the results obtained from the experiential process

By the early 20th century, the blood vessels could only be seen by anatomical studies. Shortly after the discovery of X-rays by Conrad Roentgen in 1895, the first experiments with radiographic imaging were performed with blood vessels. In 1905, the first experiment involving catheterization of arterial and venous system in dogs was performed and only in 1914 performed on living human patients. Parallel to these landmarks, there were advances in diagnostic imaging devices and the evolution of contrast substances was of utmost importance to the current angiography occupy a prominent role not only in terms of diagnosis, but also in the treatment of various disorders. The main objective of this review is to weave historical considerations and comparisons between the different methodologies used in angiography, because its importance; that may be in future, a veterinary diagnostic decisive test
