13. COMUNICAÇÃO POPULAR-ALTERNATIVA DESENVOLVIDA POR JOVENS INDÍGENAS DAS ALDEIAS DO JAGUAPIRU E BORORÓ EM DOURADOS / MS
This work approaches the alternative communication that has been developed by the AJI (Ação dos Jovens Indígenas / Teen-Indians Action), in Dourados City (MS-Brazil), at Jaguapiru and Bororó Villages, through a case study. The teenagers who produce audiovisuals, photographs, blog, photoblog, and a printed journal have found out on communication an altern

14. Geopolitics on the northern border of Brazil: the role of the armed forces in the socio-spatial transformations of Roraima / Geopolítica na fronteira norte do Brasil: o papel das forças armadas nas transformações sócio-espaciais do estado de Roraima
This research analyses recent processes of political feature that are happening in the Brazilian Amazon, with emphasis to the role of the Armed Forces in border areas of this region. Our argumentation focused on the performance of the Border Special Platoons, in the socio-economic and political context of Roraima, since the foundation of the Federal Territor

15. Estudo de proteases degradadoras de cutícula produzidas por Beauveria bassiana
The entomopathogenic fungus Beauveria bassiana is considered a promising agent of microbial control of insects considered pests of agriculture, such as, the grasshopper Rhammatocerus schistocercoides. This grasshopper attacks economically important plantations in the center-west Brazil. B. bassiana is capable to penetrate through cuticle of the host by apres

16. Epidemiological studies in the information and genomics era: experience of the Clinical Genome of Cancer Project in São Paulo, Brazil
Genomics is expanding the horizons of epidemiology, providing a new dimension for classical epidemiological studies and inspiring the development of large-scale multicenter studies with the statistical power necessary for the assessment of gene-gene and gene-environment interactions in cancer etiology and prognosis. This paper describes the methodology of th

17. MEMORY OF THE RESENTMENTS: THE ARMED REVOLT THROUGH THE BRAZILIAN CINEMA OF THE 80 S AND 90 S / MEMÓRIA DOS RESSENTIMENTOS: A LUTA ARMADA ATRAVÉS DO CINEMA BRASILEIRO DOS ANOS 1980 E 1990
The civilian-military dictatorship and the armed revolt that had an outbreak in Brazil from the year of 1964 on, worked as theme and scenery for a meaningful cinematographic production in the period of a political post-opening marking in an expressive way the culture of the 80 s and 90 s. Through videos produced throughout these years, the memory of the arme

18. Estudos da formação, estabilidade e ordenamento da fase gamma FeSi 2 produzida pela técnica de implantação iônica
In the present work we implanted Fe ions into Si samples that are subsequently recrystallized by Ion Beam Induced Epitaxial Crystallization (IBIEC) technique. Four analysis techniques (RBS, Channeling, Mõssbauer and TEM) were used in order to study the following aspects: a) phases obtained by IBIEC as a function of Fe implanted concentration; b) thermal sta

19. Método de seleção de composições coloridas TM/Landsat para análise de classes de uso da terra / Method of selection of TM/Landsat color composition for analysis of land use classes
The objective of this research is to determine the colour composites generated using digital processing (feature selection and radiometric enhancement) that enhance visual interpretation and improve the separability of land use classes in Conchal, São Paulo State. The procedure used is based on a comparison among thematic classes, taking into consideration

20. Estudo conformacional de proteínas por espectroscopia Raman laser e de absorção no infravermelho: toxina γ de tityus serrulatus e fosfolipases A2 de crotalus durissus terrificus e de pâncreas de porco e seu zimogênio / Conformational study of proteins by Raman laser and infrared absorption spectroscopies: gamma-toxin from Tityus serrulatus and phospholipases A2 from Crotalus durissus terrificus and from pig pancreas and its zymogen
Raman and infrared spectroscopies were used to investigate conformational features of some proteins of biological interest, in what concerns structural aspects of their polypeptide backbones and microenvironments of certains amino acid residue side-chains. The work has been divided in two groups as related to the systems studied: a) Toxin γ from the ven

21. Sobre a teoria das ondas de spin / On the theory of Spin waves
The mathematical formalismo f the spin wave theory is analysed. The thermodynamical equivalence between the Dyson-Malleev and Holstein-Primakoff transformations is proved. The problems involving the kinematical interaction are also discussed in detail. A new splitting of the Heisenberg Hamiltonian, perfomed in configuration space, is used to study the spin w

22. DNA-Induced Transformation in Drosophila: Evidence for Transmission without Integration*
A key feature of the exosome model of transformation in Drosophila melanogaster is that the DNA segments responsible for the phenomenon are not integrated into the linear structure of the chromosomes. This feature is confirmed by the failure to find whole-body transformants in a series of large-scale experiments, and by the absence of evidence for integratio

23. The Extreme Carboxyl Terminus of v-Abl Is Required for Lymphoid Cell Transformation by Abelson Virus
The v-Abl protein tyrosine kinase encoded by Abelson murine leukemia virus (Ab-MLV) induces transformation of pre-B cells in vivo and in vitro and can transform immortalized fibroblast cell lines in vitro. Although the kinase activity of the protein is required for these events, most previously studied mutants encoding truncated v-Abl proteins that lack the

24. The Insert Region of RhoA Is Essential for Rho Kinase Activation and Cellular Transformation
RhoA is involved in multiple cellular processes, including cytoskeletal organization, gene expression, and transformation. These processes are mediated by a variety of downstream effector proteins. However, which effectors are involved in cellular transformation and how these proteins are activated following interaction with Rho remains to be established. A
