Transformações de Lorentz e seus invariantes

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

Aikido: via para ascese marcial

Aikido is a Japanese martial art developed in the 20th century by Morihei Ueshiba. This self defense art, as it is known, is trained around the world as a noncompetitive practice. This work aimed to investigate and circumscribe the history of this martial art presenting features of its singularity. Akido´s Cultural History was used as a theoretical approach to build the historical background. The work was divided in five chapters as respectively named and described: Japan´s historical contextualization - it seeks to show the changing processes that happened in Japan which were arising from the insertion of other cultures, and how that insertion led the country to modernize itself and turn into a great world power. The ancient art: Aiki Jujutsu Daitoryu - talks about this samurai martial art which ensured the Aikido to obtain as the source technique the aiki, and the Xintoist practice. The history of a master: Morihei Ueshiba - presents some defining facts and moments from the master Ueshiba´s history, which points both to the changes occurred in the country, and to the ones that led the master to justify and broadcast the martial art. Aikido: The Budo art - portraits the Aikido´s meaning and the way that it was built to present the Aikido as a Budo art. And to finalize, Martial asceticism - seeks to make the dialogue between the cultures, from the meaning of this chapter title words (martial asceticism), as well as to point facts from the contemporaneity which provoke reflections upon the present practice

Uma discussão sobre a base metafórica das figuras de linguagem

The aim of this work is the analysis of some figures of speech, which is based on the existence of a nature of metaphorical process. The research starts from the hypothesis that these figures form themselves by this process. The study is based on the reading of the chapter “Figuras de linguagem”, which is in the work Lições de gramática de usos do português (NEVES, in the press), in which are given lessons about figures of speech, using literary texts and suggesting a metaphorical base for the general sustenance of the analyses. From these lessons, that had already directed groupings and analyses in Seves (2009), a reanalysis was done according to a theoretical orientation which basis is cognitivist, what contribute to this idea about the origin of the figurative processes. The bases of the theoretical orientation, in this sense, are: the conceptual metaphor theory (LAKOFF; JOHNSON, 1980), which considers metaphor as a cognitive (mental) process; and the current of the systematic metaphor (CAMERON, 2005 apud SARDINHA, 2007) that defends the attention to the recurring use of metaphor in real language, before doing assertions about the mind’s functioning. The analyses indicated these conclusions: a) the theory of the conceptual metaphor can be considered efficient for the foundation of the analyses, what implies a minimization of the metonymic component in the exam of these figures; b) and in the basis of the majority of the founded figures it is evident the nature of a metaphorical process
