37. Indicadores de qualidade do solo em ambientes de tabuleiros costeiros na região Norte Fluminense, RJ / Indicators of Quality of the soil in environment of Coastal tableland in the Fluminense North Area, RJ. Seropédica. UFRRJ, 2005 (Dissertation, Master in Environmental and Forest Sciences, Area of Conservation of the Nature).
Tabuleiros Costeiros é o termo utilizado para designar a feição geomorfológica ou forma de superfície do tipo tabular que pode ser observada ao longo de praticamente toda a faixa costeira do Brasil, desde o Rio de Janeiro até o Amapá. No RJ os solos de tabuleiro têm sua maior expressão na região Norte Fluminense. Este trabalho foi realizado no Muni

38. Biotechnology to improve health in developing countries: a review
The growing health disparities between the developing and the developed world call for urgent action from the scientific community. Science and technology have in the past played a vital role in improving public health. Today, with the tremendous potential of genomics and other advances in the life sciences, the contribution of science to improve public heal

39. Combinação de múltiplos classificadores para identificação de materiais em imagens ruidosas.
Material identification in images has been explored in multiple areas and very interesting applications are arising in this field. This work uses noisy multispectral images from a computerized tomograph scanner acquired with multiple energies for soil sciences applications and developes a recognition system to identify materials on the scanned body. Techniqu

40. "The Eucalyptus Planter: the Forest Preservation Matter in Brazil and the Documental Rescue of the Legacy of Edmundo Navarro de Andrade" / "O plantador de eucaliptos: a questão da preservação florestal no Brasil e o resgate documental do legado de Edmundo Navarro de Andrade"
This work aims to retrieve the historical, documental and scientific record of Edmundo Navarro de Andrade, a scientist employed in 1904 by the Companhia Paulista de Estradas de Ferro do Estado de São Paulo in order to determine which variety of tree could be better used for supplying coal to locomotives and wood for railroad ties. Navarro began his work in

41. Caracterização hidrológica de duas microbacias visando a identificação de indicadores hidrológicos para o monitoramento ambiental do manejo de florestas plantadas. / Hydrological characteristics of experimental catchments for the identification of hydrological indicators for the environmental monitoring of forest plantations.
The present work consisted of the hydrological characterization of two catchments aiming to identify hydrologic criteria and indicators that can contribute for the implementation of better management practices of Eucalyptus plantations, as well as the evaluation of possible impacts of these activities on catchment yield and quality. The experimental catchmen

42. Characterization of soils degraded by the agricultural activity and biological changes after reforestation with different species associations of the Atlantic Forest / Caracterização de solos degradados pela atividade agrícola e alterações biológicas após reflorestamentos com diferentes associações de espécies da Mata Atlântica
This study seeks to: a) characterize the degree of physical and chemical degradation of the soils used in agricultural cultivation for several decades, originally covered by the Atlantic Forest (Seasonal Semideciduous Forest) in Botucatu, SP; b) evaluate the biological changes of these soils along a 16-month post-reforestation with different models of specie

43. Refração Sísmica Profunda no Setor Sudeste da Província Tocantins / Deep Seismic Refraction on Southestearn Sector of the Tocantins Province
This work to fulfil the degree of Master of Sciences is inserted among the deep seismic refraction studies of the Thematic Project Geophysical Studies and Tectonic Model of the Tocantins Province Central and Southeast Sectors, Central Brazil . Three refraction lines, of around 300 km long each, were deployed, two of them in the Central sector and the other i

44. Lead poisoning.
Lead poisoning is the most common disease of environmental origin in the United States today. Adult lead poisoning results primarily from exposure by inhalation in the workplace. Pediatric lead poisoning results principally from the ingestion of lead from environmental media, including paint chips, dust, soil, drinking water, ceramics, and medications. Lead

45. Ice-Cap. A High-Throughput Method for Capturing Plant Tissue Samples for Genotype Analysis1
High-throughput genotype screening is rapidly becoming a standard research tool in the post-genomic era. A major bottleneck currently exists, however, that limits the utility of this approach in the plant sciences. The rate-limiting step in current high-throughput pipelines is that tissue samples from living plants must be collected manually, one plant at a
