O presente estudo analisa teses e dissertações brasileiras relacionadas com o tema Educação e Relações Raciais defendidas entre os anos de 2004-2013, cujo objetivo é identificar o que dizem as produções acadêmicas em relação à educação e relações raciais neste período. Com este intuito, foi realizada uma pesquisa do tipo qualitativa por meio da modalidade estudo bibliográfico utilizando-se o procedimento de coleta on-line de dados efetivada a partir do acesso ao sítio da Biblioteca Digital Brasileira de Teses e Dissertações. Para o tratamento das informações recorreu-se à análise de conteúdo de Bardin (2011) como aporte metodológico e ao conceito de campo em Bourdieu (1974, 1976, 1983,1994, 1995,1998, 2003), enquanto aporte teórico. O resultado da investigação aponta para a acrescente abordagem sobre o tema relações como: movimentos sociais; identidades; racismo; formação de professores; propostas e práticas pedagógicas; memórias; ações afirmativas e políticas educacionais; currículos e programas; instrumentos pedagógicos; estado da arte, concepções teóricas, dentre outros, o que possibilita a visibilidade dos debates e favorece a criação de um campo em que disputas de força e sentidos podem mobilizar um poder simbólico capaz de impulsionar a superação da condição de exclusão social presente em diferentes esferas da sociedade.

INTRODUCTION: Anabolic androgenic steroids (AAS) are frequently used by people whose aim to increase muscle mass to obtain a better performance in sports or improve physical appearance. AAS are synthetic derivatives of testosterone, able to promote muscle fibers hypertrophy, increasing intracellular protein synthesis. L-carnitine is a food supplement used to increase energetic production by means of fat acids oxidation. Although there are several works about physiological properties of these drugs, there are few studies about their mutagenic potential. OBJECTIVES: This work evaluated the clastogenicity and genotoxicity of nandrolone decanoate, testosterone decanoate and L-carnitine, in different treatments through the micronucleus test in polychromatic erythrocytes of Wistar rats. METHODS: The animals were submitted to different concentrations and associations of AAS. The positive control received cyclophosphamide 50 mg/kg by intraperitoneal injection and negative control, one ml of saline solution by gavage. The rats were sacrificed after 36 hours of latest application, having the femurs removed and the bone marrow extracted. Material was homogenized and centrifuged. Button cell was pipetted and transferred to slides, which were stained by Giemsa. 1,000 polychromatic erythrocytes were counted per animal, noting the frequency of micronuclei. RESULTS: The Kruskal-Wallis test was performed, with a significance level of 5%, which demonstrated that nandrolone decanoate - three doses of 0,2 mg/kg and 0,6 mg/kg, eight doses of 7,5 mg/kg, L-carnitine - seven doses of 0,4 ml/250 g and 1,5 ml/250 g, testosterone decanoate - 28 doses of 0,075 mg/kg, nandrolone decanoate - eight doses of 7,5 mg/kg associated to L-carnitine and 1 mL and nandrolone decanoate - eight doses of 7,5 mg/kg associated to testosterone decanoate - eight doses of 7,5 mg/kg, showed mutagenic potential. CONCLUSION: The treatments proved to be clastogenic, not being indicated like ergogenic aid.

The interview has been a widely used procedure of research in humanities. Despite the frequent use, researches are not always supported in the literature on research methodology. The aim of this study was to analyze how the interview was used in dissertations and theses in a graduate Program in Education at a university in Sao Paulo state. This study examined 167 final papers developed in to period of five years. Variables focused were: justification for the use of interview, type of interview used, guide elaboration and adaptation, kind of analysis, among others. The results showed that it is still necessary to incorporate the contents of the research methodology underlying the use of the interview to achieve the scientific rigor for this procedure.

The Assistive Technology makes the lives of people without disabilities more practical, but for people with disabilities it can make things possible. For these individuals can provide the conditions, making their limitations are not obstacles to their social and personal empowerment, and may contribute to their effective participation in tasks that were previously impossible, such as remaining seated correctly. A segment on which the necessary assistive technology works, is the adaptation of furniture such as chairs, tables, chairs-to-wheels for individuals with disabilities, as well as cerebral palsy. The study aimed to conduct a survey and brief description of theses and dissertations produced in Brazil on furniture adapted for students with cerebral palsy. We made searching in databases of libraries of major universities and federal state national banks, theses and dissertations. Nine studies were selected for description. It was concluded that there is a considerable array of professionals, both in engineering as the field of rehabilitation, to contribute in the adaptation, creation and even the manufacture of furniture for children with cerebral palsy and that the securities most studied are the chairs and their components.
