1. The Role of Terrestrial and Space Environments in Launch Vehicle Development
ABSTRACT: Natural (Terrestrial & Space) Environment (NE) phenomena play a significant role in the design and flight of aerospace vehicles and in the integrity of the associated aerospace systems and structures. Natural environmental design criteria guidelines described here are based on measurements and modeling of atmospheric and climatic phenomena relative

2. ANALYSIS OF THE PHENOLOGY DYNAMICS OF BRAZILIAN CAATINGA SPECIES WITH NDVI TIME SERIES
ABSTRACT In Brazil there are six well-defined biomes and the Caatinga represents 9.92% of the total area. This biome is exclusively Brazilian and very rich in biodiversity. Because it has low resistance to human interference is necessary to know the important factors in monitoring the biome. Vegetation coverage and climate are two of these factors, as they i

3. Modelagem estatística de extremos espaciais com base em processos max-stable aplicados a dados meteorológicos no estado do Paraná / Statistical modelling of spatial extremes based on max-stable processes applied to environmental data in the Parana State
The most mathematical models developed for rare events are based on probabilistic models for extremes. Although the tools for statistical modeling of univariate and multivariate extremes are well-developed, the extension of these tools to model spatial extremes data is currently a very active area of research. Modeling of maximum values under the spatial dom

4. Sensoriamento remoto aplicado à análise temporal da relação uso da terra/temperatura e albedo de superfície na bacia do Rio Vieira no Norte de Minas Gerais
This study aimed to analyze with the help of TM data - Landsat 5, the relationship between the changes in land use and the variation of temperature and surface albedo, during period winter in basin River Vieira for the years 1985, 1995 and 2010. The choice of river basin Vieira is justified because this area, located in the North of Minas Gerais, was the sce

5. Statistical Analysis of Spatial and Temporal Variability of Maximum Precipitation Events on the Rio Grande do Sul
Abstract: A statistical analysis of precipitation at Rio Grande do Sul State was presented in this article. The aim of this work was to identify spatial and temporal patterns of maximum precipitation, which was achieved by fitting a theoretical variogram in maximum annual rainfalls and its times of occurrence. In the literature, it was found that this patter

6. Prediction of the level of Paraguay river using neural networks.
Backpropagation neural networks are implemented for prediction of the level of Paraguay River at Ladario city, MS. Using 274 monthly mean values, the trained network predicts the levels of the four next months with relative errors smaller than 17%. For some special points, the prediction results also show that the neural network method seems to be useful to

7. Contextualização e Nterdisciplinaridade na Utilização da Matemática no Estudo de Fenômenos Climáticos e Meteorológicos. 2010. / Contextualization and Nterdisciplinaridade the Use of Mathematics in the Study of Climatic and Meteorological Phenomena. 2010
Esta pesquisa foi realizada no Instituto Federal do Norte de Minas Gerais Campus Salinas, com a participação de um grupo de alunos da 2 série do curso Técnico em Agropecuária, integrado ao ensino médio. Através de um estudo de dados climáticos e meteorológicos do município onde a escola está localizada, buscou-se mostrar para os alunos a aplicaç�

8. Eventos extremos de precipitação no leste da Amazônia. / Extreme events of rainfall in Eastern Amazon.
The aim of this study was to characterize the extreme events of rainfall in Eastern Amazon, to analyze on ocean-atmosphere conditions in global scale associated with intense occurrence periods of these events, to contribute for temporal variation comprehension of rainfall extreme events, as well as of determinant phenomena to its occurrence and to make furth

9. Mudanças paleoambientais quaternárias na região de Lagoa Santa, MG, Brasil: a palinologia como subsídio para o entendimento do padrão de ocupação humana.
The objective of this study is to determine the vegetational and climatic history of the Lagoa Santa, Minas Gerais, Brazil since the Last Glacial Maximum (LGM) and relate it with the pattern of human occupancy and to test the Arcaic Gap hypothesis, which suggests that human groups would have migrated to others areas of Brazil, due to dry climates, which woul

10. Atmospheric patterns associated with concentrations of tropospheric ozone in the metropolitan region of Sao Paulo / Padrões atmofésricos associados a concentrações de ozônio troposférico na região metropolitana de São Paulo
In the past few years, tropospheric ozone has been noticed to exceed the states environmental agency (CETESB) air quality standards more than any other air pollutant in the Sao Paulo Metropolitan Area (SPMA), Brazil. Its assumed that different atmospheric patterns are responsible for different impacts on ozone concentrations, due to already known phenomena c

11. Análise da relação entre a Lei n. 3135/2007 do Estado do Amazonas e o direito internacional à luz da doutrina antiformalista francesa
Since the 1970s, legal instruments aimed at environmental protection have been proliferating. International Environmental Law has been expanding as an answer to environmental challenges faced by mankind. Climatic changes caused by manmade greenhouse gases (GHG) emissions are probably, the greatest of such challenges, since it is directly related to the lifes

12. INFLUÊNCIA DAS TENSÕES DE ORIGEM TÉRMICA EM PROBLEMAS DE ESTABILIDADE DE BLOCOS ROCHOSOS / INFLUENCE OF THE STRESSES OF THERMAL ORIGIN IN PROBLEMS OF ROCK BLOCKS STABILITY
In 1999, the falls of rock blocks had represented about 8% of the different types of slides registered in Rio de Janeiro. The anthropic activity generates an increase of the risk areas due the building of vulnerable houses near to foot rock scarps, and an acceleration of these phenomena. Since 1993 the number of falls of rock blocks from slopes of disactivat
