It has been shown that mental rotation of objects and human body parts is processed differently in the human brain. But what about body parts belonging to other primates? Does our brain process this information like any other object or does it instead maximize the structural similarities with our homologous body parts? We tried to answer this question by measuring the manual reaction time (MRT) of human participants discriminating the handedness of drawings representing the hands of four anthropoid primates (orangutan, chimpanzee, gorilla, and human). Twenty-four right-handed volunteers (13 males and 11 females) were instructed to judge the handedness of a hand drawing in palm view by pressing a left/right key. The orientation of hand drawings varied from 0º (fingers upwards) to 90º lateral (fingers pointing away from the midline), 180º (fingers downwards) and 90º medial (finger towards the midline). The results showed an effect of rotation angle (F(3, 69) = 19.57, P < 0.001), but not of hand identity, on MRTs. Moreover, for all hand drawings, a medial rotation elicited shorter MRTs than a lateral rotation (960 and 1169 ms, respectively, P < 0.05). This result has been previously observed for drawings of the human hand and related to biomechanical constraints of movement performance. Our findings indicate that anthropoid hands are essentially equivalent stimuli for handedness recognition. Since the task involves mentally simulating the posture and rotation of the hands, we wondered if "mirror neurons" could be involved in establishing the motor equivalence between the stimuli and the participants' own hands.

Optics consists in the study of interaction of light with physical systems. The human vision is a product of the interaction of light with the eye (a very peculiar physical system). Here we present a basic study of the relationship between the optics and human vision, including: - The fundaments and physicals properties who characterize the light and the colors and the characteristics of the incidence mediums. - The basics laws of geometrical optics, based in the rectilinear propagation of light in the form of a light ray, in the independence of light rays and in the principle of reversibility of the light beams. This principle is present in the process of image formations in lenses and mirrors and applied in the study of image formation in the human eye. - The refraction and reflection laws and types of lenses, who permits the construction of optics devices for the study of physical universe, and the appliances to correct vision diseases. - Presents the human vision process as consisting in the reception of light (electromagnetic radiation in the zone of wavelength visible to us) through the eye and the sending of information obtained by the retina to the brain where it is interpreted. The vision involves a biophysical relation between the light and the biological structure of the eye who is constituted by cornea, iris, crystalline and retina. Analyzes is made of how some parts of the eye performs a function in the reception and sending of information of the images to the brain

O contexto esportivo tem sido marcado por um numero crescente de torcedores, sendo esses algumas vezes apaixonados por esporte, ou meros curiosos que acompanham matérias jornalísticas, os mesmos torcedores que vibram nos momentos de vitória e vaiam nos momentos de derrota. Podemos dizer que essa torcida poderá desequilibrar o atleta a ponto de interferir em seu desempenho e levá-lo a uma ansiedade capaz de gerar outras fortes tensões, perdendo totalmente o controle da situação pela qual está passando. As equipes desportivas devem dar uma importância maior para a preparação psicológica dos atletas em função do modo como os fatores psicológicos, os agentes causadores de estresse e a baixa alto-estima causam interferência no cotidiano de um atleta. E essa preparação é sempre colocada em segundo plano quando comparada a preparação física, técnica e tática. Este estudo tem como objetivo analisar qualitativamente qual a influência que a torcida pode exercer sobre o desempenho de atletas de voleibol durante uma partida, seja ela disputada com a torcida incentivando ou tentando atrapalhar os jogadores. Em pesquisa documental (uma entrevista feita em 1997), cujos dados encontram-se armazenados no LEPESPE, Laboratório de Estudos e Pesquisas em Psicologia do Esporte, IB/UNESP, sob código DEF/UNESP/MCZ/97, coletados em campeonatos esportivos, no estado de São Paulo, incluindo jogos oficiais da Secretaria de Esportes e Campeonatos Esportivos Universitários por equipe de pesquisadores do laboratório, percebeu-se que tanto em turmas de treinamento, como em jogos entre classes ou entre escolas é que uma primeira preocupação fica mesmo por conta do jogar para ganhar, seguida da intenção de se fazer um bom papel, uma bela figura. Os depoimentos citados mostram que os alunos são breves espelhos de seus professores, quando são bem motivados com...(Resumo completo, clicar acesso eletrônico abaixo)

This paper discusses aspects of Budapest, by Chico Buarque, published in 2003. In the novel, a contingency takes the protagonist, a Brazilian, to Hungary. There, involved within a culture quite distinct from his, he has experiences in a strange language, which “even the devil respects”, and with an interesting woman, who teaches him the language. Both, language and woman, turns into mirrors that refract and put his subjective experience, as babelic as the Hungarian, up side down. Considering contingency as a category from the Real (Lacan) and translation as mechanism of subjective search of a blot origin (Derrida), at the same time transcreation (Haroldo de Campos), we will pinpoint some ways to the novel reading.

Although the popularization of astronomy in the last decade and the International Year of Astronomy, celebrated in 2009, there's a great lack in respect of quality instruments for astronomical disclosure. Thinking in this research about it, we intend to recuperate and elucidate a technique long forgotten: the metal mirror amateur telescope, once was done in the first reflecting telescopes. However, with the resources available today and given the high purity of the materials, our results were better than that obtained by the pioneers. We developed and built a large aperture telescope (250 mm diameter) and very bright (focal ratio = 4.0), versatile and portable. In our study was described step by step the process to fabricate the telescope. Through its first images captured of the Moon, we can illustrate its versatility both for use in outreach events and for use in amateur astronomy, because it is a primary focus capture system and can run registration of various astronomical events
