O futebol nos dias de hoje representa algo muito maior do que um exercício físico ou uma atividade de descontração. Ele desempenha um papel dentro da sociedade que extrapola as perspectivas do jogo. Reduzir a análise sobre o futebol profissional apenas ao aspecto lúdico do esporte também diminui a concepção sobre o que ele realmente representa. Nos bastidores do espetáculo futebolístico existe um universo de atos políticos que abrangem diversas esferas do poder que por sua vez auxiliam na execução do esporte como um evento esportivo com milhões de espectadores. Uma das razões para que o âmbito político do esporte seja menos conhecido do que as táticas dos técnicos ou dribles dos jogadores é a cobertura feita pelos meios de comunicação. No decorrer de sua existência, o futebol se transformou em um evento globalizado que envolve em sua órbita muito mais do que apenas o aspecto esportivo. Com os anos, o esporte foi se firmando em diversos países como produto cultural e até mesmo ferramenta política. O que se vê contudo é a sobreposição midiática do jogo sobre a sua verdadeira estrutura. O entretenimento trazido pelo esporte ganha as páginas enquanto o jogo político que sustenta a realização do mesmo recebe uma atenção mais discreta das mídias. A proposta deste trabalho é analisar como foi feita a divulgação de notícias referentes à Copa do Mundo de 2014, que será realizada no Brasil, nos jornais Folha de S.Paulo e O Estado de S. Paulo durante o ano de 2012 através dos seus cadernos de esportes. O objetivo é compreender qual é o teor e a intensidade da cobertura sobre os fatos políticos que ajudam a dar forma ao evento mais importante do futebol. Acontecimentos desta proporção exigem preparação do país, o que implica em um trabalho em conjunto entre o Governo Federal e FIFA. Pretende-se analisar a contextualização feita pelos jornais em relação ao esporte ao seu aspecto esportivo, podendo...

The contemporary culture is based in a logic of acceleration and shortening of the relationships, a logic that disseminates and lodges in the subjectivity, so as to affect the most varied spheres of life. The purpose of the present work is to examine the conflicts that emerge in love relationships lived in such context. Seventy-four queries submitted by the users of two love-consultancy websites were taken as the object of our analysis. The complaints presented by the users were collated to the paradigms of relationship produced in the contemporary days. It was possible to observe that the modes of subjectification predominant nowadays can be apprehended in the love sphere of the human life and that from those modes derive most of the affective conflicts reported by people who seek advice in those websites. The sentimental hardship of these subjects denounces the ills of our days.

The purpose of this study was to evaluate the macroscopy and microstructure of a double setting alpha-tricalcium phosphate bone cement sphere provided with interconnection channels (alpha-TCP-i), as well as the integration of the implant with the rabbits' orbital tissue, through macroscopic analysis and histopathology. The external and internal surfaces of the alpha-TCP-i were evaluated macroscopically and by electron microscopy. Twelve New Zealand rabbits received 12mm implants of alpha-TCP-i following enucleation of the left eye. The clinical assessment was undertaken daily during the first 15 days, followed by fortnightly assessment until the end of the study period. For the morphological analysis, exenteration was performed in 3 animals per experimental period (15, 45, 90 and 180 days). The external and internal surfaces of the implant appeared solid, smooth and compact, with six channels which interconnected centrally. The micro-architecture was characterized by the formation of columns of hexagonal crystals. No signs of infection, exposure, dehiscence of sutures or extrusion of the implant were noted in any of the animals during the entire period of the study. The morphological evaluation demonstrated the presence of a thin capsule around the implant, from whence appeared fibro-vascular projections, which penetrated it through the interconnecting channels. In the first days after the insertion of the implant, an intense inflammatory reaction was noted. At 180 days, however, there were no signs of inflammation. The alpha-tricalcium phosphate cement implant was well tolerated in this rabbit model and appeared to be relatively inert with some fibrovascular ingrowth through the large channels.

The aim of this research was to evaluate, by preference tests, the ability of perception of broiler chicks in the recognition of objects and foods of different colors. The survey was conducted in Brazil and consisted in the conditioning of 60 sexed one-day-old chicks using 30 male chicks and 30 female chicks for three days with blue balls and red food colors chosen for having opposed chromaticities. After the conditioning phase, a preference test was performed, in which the animals were placed individually in the center of an arena test with four options: red food, blue food, red balls and blue balls. Each bird was measured for 10 minutes. Latency to the first peck and the number of pecks, the number of sequential pecks at each object type or food, the total time the bird in each occupied compartment and the first occupied slot were recorded. According to the results, female chicks are less inhibited when in contact with a new situation when compared with males. However, males were able to establish a standard environment in the conditioning phase and opted for the compartment which was closer to that situation, associating the blue color to the ball and red color to the food. Overall, among the types of object colors and between types of food colors, the birds took less time for the decision on the choice of blue food and blue ball, showing a greater attraction, at first, to this color. Between the two ball colors, shorter latency period, greater number of interactions as well as more time spent on site were related to the blue sphere, verifying greater preference for this object. When evaluating the types of food colors, it was observed that the highest averages related to the number of pecks, and sequential pecks occurred with red food. Therefore, it is concluded that the birds recognized the red and blue food object, with the blue color having greater attractiveness for broiler chicks when compared to red.

This article is the result of a narrative literature review. The objective is to show the development of an overview on the ideological debate on the design of state health policies. We argue that the role of the state in the development of health policy, even under the pressure of the global market, may create alternatives to promote and drive economic and social development, meaning they are not subject to economic constraints imposed by the liberal ideal of market. Here is a part of a theoretical discussion about the construction and presence of the State in Latin America, particularly in Brazil. We take the approaches of the Marxist tradition and liberal to the issue as reference. This discussion allows us to understand the historical role of the state in the maintenance of social policies, specifically health, is an alternative to public control eases the intense capital mobility promoted by economic globalization. In this sense, the theme makes the Brazilian health an important issue of social sciences, why is the historicity of the construction of the Brazilian health system, as a public policy that can mirror the actual reconstruction of the institutional framework of the Brazilian state with the establishment instances of negotiation between the various spheres of power that strengthen the state in this process of democratization of Brazilian society.

Brazilian southeastern region has soil and climate conditions suitable for the growing of rubber trees, and most part of national yield arises from São Paulo State. The aims proposed for this work were to determine the diversity, the richness and the seasonal occurrence of mites found in a rubber tree crop in a triennial survey with monthly samplings, as well as to estimate the populational density of the major phytophagous species. This study found 74,407 mites from 26 species belonging to 10 families. The phytophagous and predators represented 95.4% and 3.9% of the total abundance, respectively. Twelve species were rare, six accessories and eight constant. The families Phytoseiidae and Tydeidae had the greatest richness (five and four species, respectively). The most numerous species was Calacarus heveae Feres (50,573), with great abundance at the end of rainy season until the beginning of dry season. Among predators, the most abundant were Zetzellia quasagistemas Hernandes & Feres (1,345), Pronematus sp. (455), Zetzellia agistzellia Hernandes & Feres (409) and Euseius citrifolius Denmark & Muma (243). C. heveae had greatest densities on March and April 2003, and Lorryia formosa Cooreman and Tenuipalpus heveae Baker on March and May 2001, respectively. Many stigmaeids were observed in association with colonies of L. formosa preying their eggs and immatures.

In this work we present a didactic proposal to use song lyrics for Physics Teaching aimed to High School level. Based on the work proposed by Zanetic (1990) that Physics is also Culture, we understand that its influence extends beyond the scientific boundaries, reaching spheres of knowledge where its presence is less obvious, such as the arts, especially Music. Based on proposals for Ramos and Gomes (2013), activities were conducted in two groups of second year of high school in the city of Rio Claro, each with an approach. In one of the classes the students received as material the lyrics of the songs printed and the other students were given a table along with the lyrics. In these materials the students identified physical concepts present in the songs Nuclear Shelter of the São Paulo band Premeditando the Breque and Manhattan Project of the Canadian band Rush. We observed during activities an improvement in the participation of students in theoretical discussions, probably due to a more favorable context for students to express themselves assigned by us to the activities with the songs. After performing the activities we demonstrated that you can enter the Music in the classroom not only as entertainment but as an aid in research and understanding of physical concepts

The technique proposed aims at reducing the weight of individualized ample ocular prostheses using acrylic resins as well as simplifying laboratory procedure. For that, prefabricated hollow spheres made of plastic material, were inserted in the sclera. The average weights of the solid conventional sclera (5.30g) and those of the respective prefabricated plastic ones (3.91g) were compared. The weight reduction was significative with a confidence interval of 95% by the Student t test. ln addition, for illustration purpose, the technique was applied to patients in the ward of the Maxillofacial Prostheses Dicipline of the Dentistry School in the Campus of São José dos Campos - UNESP, having each patient received a solid prosthesis and a hollow prefabricated one made of plastic material. It has been concluded that the prostheses material spheres were inserted are lighter than the ones which received solid spheres; furthermore, thr technique is viable for ample anophtalmic cavities and requires few sessions
