13. Na beira do rio tem uma cidade: urbanidade e valorização dos corpos d água
Urban occupations along water bodies margins are the theme of this thesis. Waterside spaces carry dichotomic relations that are not hitherto considered to the degree of their complexity and importance to socio-environmental dynamics. The relevant environmental functions performed by these spaces justified their categorization as Permanent Preservation Areas/

14. Aplicação de dados hyperion EO-1 no estudo de plantação de euclalyptus spp / Application of hyperin EO-1 data in eucalyptus spp. plantations
A disponibilidade de dados hiperespectrais trouxe expectativas nos meios acadêmicos e empresariais quanto à potencialidade de sua aplicação no setor florestal. O objetivo deste trabalho foi avaliar o potencial e as limitações da aplicação de dados hiperespectrais do sensor Hyperion EO-1 no estudo de plantações de Eucalyptus spp. Para tanto, foram a

15. Estudos estruturais do domínio catalítico da proteína tirosina fosfatase eta de rato / Structural studies of the catalytic domain of the rat protein tyrosine phosphatase eta
The rat protein tyrosine phosphatase eta, rPTPeta, is a transmembrane RPTP, with an intracellular portion composed of a unique catalytic region. The rPTPeta and the human homolog DEP-1 are down-regulated in rat and human neoplastic cells, respectively. However, the malignant phenotype is reverted after exogenous reconstitution of rPTPeta, suggesting that its

16. Vieira river quality under Montes Claros/MG urban area influence / Qualidade da Ãgua do rio Vieira sob a influÃncia da Ãrea urbana de Montes Claros MG
The object of study in this research is the Vieira river flowing through Montes Claros, Minas Gerais. Montes Claros, a city of about 348.996 inhabitants (according to IBGE data from july/2006), occupies a reasonable portion of the river basin and, therefore, has great influence on the water quality. This master s degree thesis tried to understand the cause-e

17. Estratégias para prospecção e predição de peptídeos bioativos
Chapters one and two deal with the isolation and identification of bioactive peptides from the skin secretion of Phyllomedusa hypochondrialis. The first chapter demonstrates the use of protemic techniques, mainly mass spectrometry, for the study of bradykinin related peptides (BRPs) present in the amphibians secretion and freshly dissected skin fragments.

19. P-Band radar data classification by neural network for Amazonin land cover assessment / Uso de rede neural artificial não supervisionada na classificação de dados de radar na Banda-P para mapeamento de cobertura da terra em floresta tropical
The applicability of P-band radar data for land cover mapping using the unsupervised artificial neural network Fuzzy-ART (Adaptive Resonance Theory) is evaluated. The study area is located near Tapajós National Forest in the State of Para, Brazil. The radar data was acquired during an airborne mission conducted by AeroSensing RadarSystem GmbH in september 2

20. Desenvolvimento fenologico do trigo (cultivar IAC 24 - Tucurui), comportamento espectral e utilização de imagens NOAA-AVHRR
The agronomic development of wheat (Triticum aestivum L.) cultivar IAC-24 - Tucuruí and the seasonal evolution of its spectral characteristics were evaluated under field conditions. The study was carried out at an irrigated commercial farm, located in the municipality of Paranapanema, SP. Field experimental observations were collected during the 1995 growin

21. Estimativa de propriedades biofísicas de plantações de eucaliptos a partir de dados Landsat-TM / Biophysical properties estimation of eucalyptus plantations from TM/Landsat data
In this study we carried out a feasibility assessment of remote sensing techniques to estimate Leaf Area Index (LAI), Diameter at the Breast Height (DBH), Height and the Age of different \textit{Eucalyptus} genetic materials, from 12 to 78 months of age. The test-area is the Aracruz regional from Aracruz Celulose S.A., in the Espírito Santo State, Brazil. I

22. Índices de vegetação e valores de proporção na caracterização de floresta tropical primária e estádios sucessionais na área de influência da Floresta Nacional do Tapajós-Estado do Pará / Vegetation indices and fraction values to characterize primary rainforest and sucessional stages in the area of influence of Tapajos National forest - Para State
In May 1995, a field campaign was carried out in the innerside and proximities of Tapajós National Forest - Pará State, aiming to measure dendrometric variables and leaf area index (LAI) in vegetation communities of tropical rainforest and regrowth, represented by three stages, c1assified in function of age: less than 5 years; 5 to 10 years and more than 1

23. Modificações das propriedades anisotropicas e de resistencia a tração de tendões calcaneares de ratos submetidos ao exercicio fisico e a denervação
For the purpose of determ1n1ng the modifications of tensile strength and of the d1fferent levels of macromolecular or1entation in collagen bundles due to mechanical stimuli, rats were submitted to different experimental treatments, such as physical exercise and muscular denervation. After these treatments the Achilles tendons of animais were subm1tted to b
