Numerous studies in physical education and music's area have been conducted to improve the quality of life and health of people, all of them under physiological, psychological and social fields. Thus, when properly analyzed, both Areas are connected, because the movement itself, main subject of physical education, has a close proximity to the rhythm, an essential element of music. That's why it is important to discover the benefits of this relationship, because, in many of its practices, physical education makes use of music, for example, in aerobic gymnastic and dance classes. As a consequence, this study aims to investigate, through literature, the influence of music in physical activities and its imprinting in the states of mind and body of practitioners, as well as clarify the criteria for choice of songs that are used in such practice. This research occurred under literary explore, done through theoretical analysis of the thematic. At first place, a contextualization of the auditory system and its relationship with the music and the perception of sound were made, then the main theme was explored. The music, even before generate and influence motor and psychic movements in the human body, is already moving in space, because it is formed through vibrations of molecules. It is decoded first as a movement from the ears, and then decoded as sound, when in the brain. It is important to worry about sounds at high intensities and also with those which are outside the hearing thresholds within physical activities involving music, because they may be harmful to health and also to states of mind. As far as music and movement is concerned, they are closely linked, and the human being has an instinctive sense of rhythm that can be seen when listening to music, because the motor cortex is also activated. Therefore, it is important to work the sound and body movement together, because in practice they are inseparable and they contribute greatly to...

Dental plaque is the principal etiological agent of periodontal disease, one of oral diseases more prevalent in the world. Due existence of relation between periodontal disease and oral hygiene, on the point of periodontal view, it was developed a growing interesting by experimental research and by clinical investigations. The knowledge of problem, its extension, severity, hypothetic cause is so valuable to establish prevention, control and treatment acts. In this form, the use of plaque index becomes more and more often, being valuable the determination of discriminatory power of them. The aim of this work was to describe and analyze principal forms to register of dental plaque aiming to subsidize the researcher and dental surgeon on adoption of most adequate method for their case. Data bases: Medline, Lilacs and BBO were consulted without limit to identify the format of register of each index described on literature. It was observed the use of Oral Hygiene Index on diverse ways like: clinical evaluation of dental plaque, in products evaluation works and dental Office; patients monitoring; instruction about hygiene and oral hygiene technique. It was noted that dental plaque indexes are useful and allows the register of different forms point out the importance of its use on clinical and researches practice.

The different kind of appliances for the treatment of posterior crossbite make that the orthodontist assess some criterions for their selection and success for the treatment. The aim of this paper was to compare two methods of treatment of the posterior crossbite by two case reports treated with Quad-helix and removable plate. Concluding that the Quad-helix is the appliance of first choice in relation of the removable plate for the short time of active treatment, the less visits and chair time, the fewer cost of treatment and the smaller cooperation of the patient.

A energia eólica é uma forma de energia que seu uso encontra-se em expansão, e junto a esse crescimento, tem-se também o aumento da quantidade de resíduos gerados na fabricação das pás eólicas. Uma forma correta de destinação e aproveitamento desses resíduos é a reciclagem. Porém, esses são constituídos de materiais compósitos, geralmente a resina epóxi e a fibra de vidro; e por possuírem um polímero termofixo (a resina epóxi) na sua composição, a reciclagem convencional via fusão não é possível. Desta forma, a reciclagem química via pirólise apresenta-se como uma alternativa para o aproveitamento desses resíduos, em especial da fibra de vidro que o contém. Após caracterização do resíduo de uma indústria de pás eólicas, verificou-se que se tratava de um material com mais de 70% de fibra de vidro e muito densas. Foram realizados ensaios de pirólise a seco e com óleo de babaçu, considerado o mais interessante perante vários possíveis e no qual o resíduo fica totalmente imerso, facilitando o inchamento e a troca de calor. Em um sistema de aquecimento com vácuo, foram obtidas mais de 97% de fibras em 30 minutos a 310 oC, justamente a temperatura em que uma análise termogravimétrica apontou ser a de início de altas taxas de degradação térmica.

The question related to recyclable material has been pointed by environmental researchers as one of the most serious urban problems today. Therefore, the importance of disclosure and clarification related to recycling techniques is highlighted, as well as a critical and extensive reflection related to the cultural values of society about current economic rationality that prioritizes a unlimited consumerism. We conducted a survey in the city of Bauru and asked how often people separated recyclable materials for selective collection. We found that 18% of these people have never performed this type of activity. Thus we emphasize the importance of art in creating alternative ways of dealing with the recyclable material, that involves social, economic and cultural needs of a population; contributing to preserve the environment such as the creation of a new rationality.

The recycling in Engineering can be used for reuse of material disposed remains into the environment. The recycling of construction residues comes from antique and was applied in the reconstruction of Europe after World War II. From the environmental point of view, the main problem with the residues that can be recycled, is related to its irregular deposition and the large volumes produced. In this article we aim to approach the recycling techniques through literature surveys and propose techno-artistic works that solve the problem of wasting residues in our planet.

A reciclagem é uma importante ferramenta para a gestão dos Resíduos Sólidos Domiciliares, como cita a Política Nacional dos Resíduos Sólidos. Assim esta pesquisa visa quantificar o impacto ambiental que um programa de reciclagem, com o objetivo de reciclar 20% dos resíduos passíveis de reciclagem, causaria na cidade de Cachoeira Paulista/SP. Para isso, foi utilizado o Waste Reduction Model para simular os dados e calcular a Emissão dos Gases de Efeito Estufa (MTCO2E e MTCE) e quantidade de Energia (Kwh). Um programa de reciclagem de 20% tem oportunidade de reduzir, em um ano e em relação a situação sem reciclagem, aproximadamente em 49% a quantidade de CO2 e C equivalentes, além de economizar em Kwh o equivalente ao gasto por um mês de energia elétrica de 9400 residências.

This paper has two main objective the study of the productive space circuit of fertilizers in Brazil. For this, we study the company's operations Vale Fertilizers SA More specifically, the production and consumption of fertilizers in Brazil. In the current globalization the Brazilian countryside know new ways of doing (SANTOS, 1994). This, with less roughness, adopts the Green Revolution package, and introduces inputs to the soil, such as seeders, combines, tractors, herbicides, fungicides and fertilizers (Santos & Silveira, 2001). The examination of the Brazilian case as the agricultural modernization reveals the great vulnerability of modern agricultural regions in the face of globalizing modernization (Santos, 2000: 92). The places that receive capital reproduction of imperatives gain a new medium, is the formation of informational scientific technical means, are the bright spots corresponding to other places (Santos, 1994). Thus, the productive circuits are no longer confined to the environment, but establish connections with distant places (Santos, 1986; Frederick & CASTILLO, 2004). What's more, the policy is now made in the market (Santos, 2000, p.67) and the adoption by the Brazilian government's neoliberal policies, the Brazilian state-owned companies related to fertilizer production circuit are privatized, thereby Brazil makes It is further more dependent on inputs used in the field, including fertilizers
