This work has as its theme the multiculturalism, cultural diversity and their reflections in school everyday, more specifically on the interactions between the various subjects and social groups that make up a school and the teacher as mediator of the relationship between these guys. The theme Multiculturalism refers in the first instance, to the theoretical movement beginning in the mid-20th century in the United States and that spreads in the Western world as a way of tackling the conflicts generated depending on the economic issues, policies, and, in particular, cultural-ethnic, in an attempt to combat discrimination and prejudice, given the difficulties of individuals and groups to welcome and socialize with the plurality and cultural differences (SILVA; BRANDIM, 2008).At the same time, multiculturalism refers to cultural studies, through the Centre for Contemporary cultural studies, founded by em1964 Hoggart, and connected to the English language Department of the University of Birmingham in England.In contemporary times, due to the phenomenon of globalization and public policy to challenge prejudice and discrimination the subjects and social groups, regardless of color, creed, ethnicity, sexual orientation and nationality, this theme has been recurring in order to recognize plural identities and ensure and directly affects the school as a place of cultural diversity and conflicts generated by the very diversity.The present work aims to analyze and understand how the issue of multiculturalism and cultural diversity in school films. Our study will be based theoretically in Cultural Studies authors and uses the qualitative approach, working with movie content analysis of school, seeking to seize on the same relations of coexistence, conflicts and the mediations of teachers

Using the sol-gel process, organic-inorganic hybrid coatings were synthesized by incorporation of different concentrations of functionalized carbon nanotubes, to improve their mechanical strength and thermal resistance without changing its passivation character. The siloxane-PMMA hybrids were prepared by radical polymerization of methyl methacrylate (MMA) with 3-methacryloxipropiltrimethoxisilane (MPTS) using the thermal initiator benzoyl peroxide (BPO), followed by acid catalyzed hydrolysis and condensation of tetraethoxysilane (TEOS). The analysis of pristine and functionalized carbon nanotubes was carried out using Scanning Electron Microscopy, X-ray Photoelectron Spectroscopy and Raman Spectroscopy. Structural analysis of hybrids was performed by Nuclear Magnetic Resonance, Atomic Force Microscopy and Raman Spectroscopy. For analysis of mechanical strength and thermal stability were performed mechanical compression tests and thermogravimetric analysis, respectively. Electrochemical Impedance Spectroscopy was used to evaluate the corrosion resistance in saline environment. The results showed an effective functionalization of carbon nanotubes with carboxyl groups and conservation of its structure. The hybrids showed high siloxane network connectivity and roughness of approximately 0.3 nm. The incorporation of carbon nanotubes in the hybrid matrix did not change significantly their thermal stability. Samples containing carbon nanotubes exhibit good corrosion resistance (on the order of MΩ in saline environment), but the lack of complete dispersion of carbon nanotubes in the hybrid, resulted in a loss of mechanical and corrosion resistance compared to hybrid matrix.

Although they are no longer manufactured, the applicators of 90Sr +90Y acquired in the decades of 1990 are still in use, by having half-life of 28.5 years. These applicators have calibration certificate given by their manufacturers, where few have been recalibrated. Thus it becomes necessary to accomplish thorough dosimetry of these applicators. This paper presents a dosimetric analysis distribution radial dose profiles for emitted by an 90Sr+90Y betatherapy applicator, using the MCNP-4C code to simulate the distribution radial dose profiles and radiochromium films to get them experimentally . The results with the simulated values were compared with the results of experimental measurements, where both curves show similar behavior, which may validate the use of MCNP-4C and radiochromium films for this type of dosimetry

Várias resoluções e leis visam minimizar e/ou adequar os resíduos gerados, dentre outros aspectos. Nesse sentido, a Disciplina de Radiologia, funcionários que trabalham no setor e docentes ligados a biossegurança e sustentabilidade ambiental estudaram as referidas normas e leis, além de artigos científicos relacionados ao descarte dos resíduos gerados em radiologia para realizar o descarte correto desses materiais e para orientar e conscientizar os acadêmicos sobre o assunto. Verificou-se que os resíduos gerados com a radiografia convencional são considerados resíduos químicos (tipo B) e devem ser descartado separadamente dos resíduos tipo A (infectantes), C (radioativos), D (comum) e dos E (perfuro-cortantes), visto que podem ser reutilizados, recuperados ou reciclados, e em última instância, podem ser dispostos em aterro de resíduos perigosos Classe I.

The article entitled Cultural Practices in Teaching Portuguese for Foreigners aims to disseminate teaching practices facing the language teaching to students from Guinea Bissau or whom the Portuguese of Portugal is the official language. We seek to problematize the course given to those students with the purpose of appropriating the " resources of expression" for approval in subjects who were enrolled in Brazil in the first half of undergraduate Letras course in a higher education institution.

Investimentos em Pesquisa, Desenvolvimento e Inovação são as formas mais eficazes para se tirar e manter países fora da recessão [1]. Nesse artigo, vamos avaliar o impacto da crise de 2007/2008 sobre os investimentos diretos estrangeiros1 na América Latina em Pesquisa e Desenvolvimento, procurando entender porque os investimentos em alta tecnologia são tão baixos na região, uma vez que seriam uma forma bastante eficaz para o desenvolvimento regional.
