13. A influência do sistema Faxinal no Estado Ambiental da Bacia Hidrográfica do Rio Sete Saltos - PR
The Hydrographical Basin provides among its many potential natural features, such as, being a unit of management natural resource for easy definition. However, to diagnose the interaction between the physical and biotic aspects it is necessary to use techniques that allow this task. In this research it was used the Physical-Conservationist Diagnostic methodo

14. Geomorphometric analysis of SRTM data applied to the study of soil relief relations / Análise geomorfométrica de dados SRTM aplicada ao estudo das relações solo-relevo
Este trabalho visou levantar conhecimento sobre as relações solo-relevo pela avaliação conjunta de dados geomorfométricos e mapas publicados de solos. Para tal, foram utilizados dados de altitude da missão SRTM (Shuttle Radar Topography Mission), variáveis geomorfométricas locais do banco de dados topográficos TOPODATA e variáveis geomorfométricas

15. Gênese, classificação e mapeamento de solos desenvolvidos de rochas pelíticas em áreas cultivadas com eucalipto em Minas Gerais / Genesis, classification and mapping of soils developed from pellitic rocks in areas cultivated with eucalyptus in Minas Gerais
Because the demand for arable areas has turned very intense in the last years, soils then considered as not appropriate to agricultural use are now being revalued and studied in order to use them for forest plantings, to example of Cambisols developed from pellitic rocks of Bambui Group. In reason of the expressiveness of these soils, usually associated Lato

16. Water Balance Model in a watershed micro basin covered by eucalypt culture / Modelagem do balanço hídrico em microbacia hidrográfica com plantio eucalipto
Every production tasks such as the raw material woods - growth using homogeneous reforestation and species that show quickly grow has caused environmental impact. The homogeneous reforestation, showing quick growth, has been considered in many studies because of its environmental impact and water consumption. This works purpose is to improve the water balanc

17. Sensoriamento remoto e geoprocessamento na caracterização e avaliação pontual e espacial de solos e seus atributos / Remote sensing and geoprocessing on punctual and spatial characterization and evaluation of soils and their attributes
The necessity of new techniques to obtain information about soil and its attributes, in a faster and cheaper form, turns remote sensing and geoprocessing into important options. These techniques allow the analysis of a great amount of data at the same time and associate spectral information with other environmental variables such as geology and relief. The o

18. VariÃveis ambientais e a distribuiÃÃo de espÃcies arbÃreas em uma floresta estacional decidual no TriÃngulo Mineiro / Environmental variables and distribution of trees in a dry deciduous forest of a TriÃngulo Mineiro
The objective of the present study was to characterize the phytossociological structure of trees in a dry deciduous forest and to correlate the distribution of the most abundant species in the forest with environmental factors (soil and topography). For the phytossociological survey fifty 10m x 20m plots were laid out, totaling 1 ha, where all the trees with

19. Variáveis ambientais e a distribuição de espécies arbóreas em uma floresta estacional decidual no Triângulo Mineiro / Environmental variables and distribution of trees in a dry deciduous forest of a Triângulo Mineiro
O objetivo do presente estudo foi de caracterizar a estrutura fitossociológica do estrato arbóreo de uma floresta estacional decidual e relacionar a distribuição das espécies mais abundantes da floresta com fatores ambientais (solo e topografia). Para o levantamento fitossociológico foram utilizadas 50 parcelas de 10m x 20m, totalizando 1 ha, onde todo

20. Caracterização e classificação de solos da Ilha de Fernando de Noronha (PE)
In the main island of Fernando de Noronha Archipelago, the dry tropical climate with oceanic influence and the recent parent material of volcanic origin, are responsible for the small weathering of soils with high scientific importance for the development of the Brazilian System of Soil Classification (SiBCS). Seven representative soil profiles, involving tw

21. Estudo do comportamento termodinÃmico das Ãreas centrais de negÃcios de BrasÃlia e de Taguatinga, Distrito Federal
The study of the climate is part of the urban environmental dimension and has been contributed towards the matters of the environment of the cities. The understanding of the urban climate as an important component in the constitution of the environment is one of the greatest issues of the modern world. This essay gets methodological reference from the thermo

22. Soil fertility and 137Cs redistribution as related to land use, landscape and texture in a watershed of ParaÃba state / Fertilidade do solo e redistribuiÃÃo de 137Cs em funÃÃo da cobertura vegetal, relevo e classes texturais, em uma microbacia hidrogrÃfica do estado da ParaÃba
Intensive land use and growing deforestation of the natural vegetation in Northeastern Brazil have contributed to the degradation of resources, particularly the decrease of soil fertility. As a result, biodiversity and ecosystem capacity to restore its resources after disturbances have been diminished. The decrease in soil fertility is more substantial in ar

23. Soil carbon sequestration - Evaluation of its potential in pastures on sandy soils, Anhembi - Piracicaba/SP / Seqüestro de carbono nos solos - Avaliação das potencialidades dos solos arenosos sob pastagens, Anhembi - Piracicaba - SP"
The project studied the potential for soil carbon sequestration in pastures growing on sandy soils in the Cerrado region and for the application of remote sensing techniques for estimating carbon sequestration levels. The main focus was deducing how many tons per hectare could be sequestered if better pasture management techniques were adopted. Four pastures

24. ANÁLISIS DE PROBLEMAS GEOTÉCNICOS A TRAVÉS DE REDES NEURALES / ANALYSIS OF GEOTECHNICAL PROBLEMS WITH NEURAL NETWORKS / ANÁLISE DE PROBLEMAS GEOTÉCNICOS ATRAVÉS DE REDES NEURAIS
During the last years, neural networks applications have been disseminated in many knowledge areas, including civil engineering. In the middle 90`s, a research work had been started in Brazil, in order to investigate the efficiency of neural networks in the analysis of soil behavior and problems involving geotechnical engineering. This thesis is the result o
