13. Transição agroecológica em Rondônia : a Associação dos Produtores Alternativos de Ouro Preto do Oeste
The colonization of the agricultural frontier in the Amazonian state of Rondônia was accelerated in the years 1960s and 1970s. This movement encouraged the consolidation of the modernization of agriculture, a process observed in south and southeast of Brazil. The agriculture practiced by thousands of migrants, consisted of cutting down and burning the fores

14. Avaliação do dano radioinduzido, capacidade de reparo e morte cecular em células humanas tumorais (T-47D e MCF-7) e não tumorais (MCF-10) de mama / Evaluation of the radioinduced damage, repair capacity and cell death on human tumorigenic (T-47D and MCF-7) and nontumorigenic (MCF-10) cell lines of breast
Breast cancer is one of the most common malignancies that account women, representing about one in three of all female neoplasm. Approximately, 90% of cases are considered sporadic, attributed to somatic events and about 10% have a family history and this only 4 - 5 % is decurrent of hereditary factors. In the clinic, ionizing radiation is a major tool utili

15. Mobile linear traffic simulator method to forecast behavior and performance of asphalt pavements. / Método de uso de simuladores de tráfego linear móvel de pista para a determinação de comportamento e previsão de desempenho de pavimentos asfálticos.
Full-scale accelerated pavement testing is defined as the controlled application of a wheel load in a pavement structure to determine the pavement system response and its performance under accelerated conditions of accumulated damage in a compressed time period (METCALF, 1996). Loads at or above the legal maximum allowed by highway agencies can be applied at

16. Geoprocessing in the analysis of the occupation and land use in areas of urban expansion : case study of the Ribeirão dos Pires sub-basin, district of Limeira (SP) / Geoprocessamento na analise da ocupação e uso da terra em areas de expansão urbana : estudo de caso da sub-bacia do Ribeirão dos Pires, municipio de Limeira (SP)
The socio-spatial transformations occurred in geographic space are becoming increasingly accelerated in modernity. Thus, it is necessary to the development of research to promote a critical understanding of the contradictions found in the production of space. The use of techniques of geoprocessing as subsidy to the analysis of the dynamics of occupation and

17. Multinational management - paths of Brazilian companies internationalization and subsidiaries management strategies. / Gestão de multinacionais: análise de trajetórias de internacionalização de empresas brasileiras e de estratégias de gestão de subsidiárias.
The changes in the competitive environment in mature consuming markets, the increase on the number of competing companies and the accelerated propagation of new knowledge and technologies have been producing alterations in company strategies and contributing for the enlargement of internationalization process. Brazil is inserted in this process, extending it

18. Modificação do Poli(hidroxibutirato) PHB com nucleantes e com o copolímero (etileno-co-acetato de vinila) - EVA
In this work, we sought to modify PHB, processing it in the melted state, and to evaluate the effect of the modifications on its mechanical properties and biodegradation characteristics. The following systems were therefore studied: a PHB/EVA blend, in a 90/10 ratio, with an ethylene-co-vinyl acetate copolymer containing 28% of VA; a PHB and PHB/EVA blend wi

19. Evolução temporal da cobertura vegetal do manguezal do Rio Tavares (Florianópolis - SC) empregando sensoriamento remoto e SIG
The Marine Extractive Reserve of Pirajubaé (REMP) is a pilot area located within the mosaic comprised of the coastal and marine units of Santa Catarina, and represents an ideal sample for the development of integrated actions in the biological, administrative and institutional fields. The aim of this study was to interpret the processes of colonization of t

20. An euclidean approach as a method to study the Unruh effect / Uma estratégia euclidiana para o estudo do efeito Unruh
This paper proposes a Euclidean strategy to understand the Unruh effect. On that ground we first study it for free massless scalar fields the way it is usually presented to pliysicists, which is closer to Unruhs original work [32]. Then we infer the effect from an algebraic perspective. We study the proprieties and definitions of KklS states in order to unde

21. Environmental factors influence evaluation on the structure, dynamics and optical properties of the aquatic humic substances form the "Rio Negro" - Amazonas / Avaliação da influência de fatores ambientais na estrutura, dinâmica e propriedades ópticas das substâncias húmicas aquáticas do Rio Negro
Nowadays, one of the major world concerning is focused in the increasing of the damaging ultraviolet (UV) radiation and its impact on the aquatic ecosystems. In addition, the Rio Negro, one of the principal tributaries of the Amazon Basin, is an appropriate site for studying the influence of the UV radiation in the dissolved organic matter (DOM) biogeochemis

22. Influência de antibióticos na morfogênese in vitro, transformação genética e isolamento de RNA de urucum (Bixa orellana L.) / Influence of antibiotics on in vitro morphogenesis, genetic transformation and RNA isolation of annatto (Bixa orellana L.)
The manipulation of genes involved in carotenoid biosynthesis in Bixa orellana has been attempted with the objective of generating plants producing high content of a natural natural colorant, bixin, and studying the biosynthetic pathway for the accumulation of this unique carotenoid in annatto seeds. The biotechnology, by means of plant tissue culture techni
