1. Long-term correlation of the electrocorticogram as a bioindicator of brain exposure to ionizing radiation
Understanding the effects of radiation and its possible influence on the nervous system are of great clinical interest. However, there have been few electrophysiological studies on brain activity after exposure to ionizing radiation (IR). A new methodological approach regarding the assessment of the possible effects of IR on brain activity is the use of line

2. Sistema de monção da América do Sul: início e fim da estação chuvosa e sua relação com a Zona de Convergência Intertropical do Atlântico / The south american monsoon system: onset and demise of the rainy season and its relationship with the Atlantic Intertropical Convergence Zone
Physical, dynamic and thermodynamic aspects related to the South American Monsoon System (SAMS) are investigated for the 1979-2006 period. A new methodology to determine the onset and demise dates of the rainy season (ONR and DER, respectively) related to the SAMS is developed using the field of antisymmetric outgoing longwave radiation in relation to the eq

3. 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

4. Seasonal characterization of the Net Radiation and energy balance on the Mundaú-Manguaba Estuary-Lagunar Complex (Alagoas). / Caracterização sazonal dos balanços de radiação e energia no Complexo Estuarino-Lagunar Mundaú-Manguaba (Alagoas).
The largest Brazilian area of mangroves is the second in the world and the first of th Americas. The knowledge of interaction this ecosystem with the atmosphere is important, because haven‟t a lots of meteorological papers about this subject, especially by the fact that environmental degradation modifies the ecosystem microclimate. Therefore, the study

5. O impacto da vegetação nos microclimas urbanos / The Impact of vegetation in urban microclimates
The main purpose of this research is the effects of vegetation in urban microclimate conditions, under the premise that the presence of vegetation influences the microclimate and its surroundings. Considering different forms of green space distribution and using native species, it could quantify the intensity and spatial distribution for the microclimate eff

6. Interdecadal variability of precipitation in the Western Brazilian Amazon / Variabilidade interdecadal da precipitação na Amazonia Ocidental brasileira.
The present work focused on the interdecadal variability of precipitation in the Western Brazilian Amazon in order to help improve this knowledge and, in addition, to analyze, study and evaluate the low-frequency variability of the hydrological cycle in this region. To this end, we used data collected from conventional rain gauge stations 5, available at the

7. Microclimate characterization of the protected environment cultivated with french-beans / Caracterização do microclima de ambiente protegido cultivado com feijão-vagem
The protected environment changes the meteorological elements in its interior related to the outward environment. The french-beans culture is considered a high risk one, being so sensitive to adverse meteorological conditions. The cultivation in protected environment may become viable the production in South Region under unfavorable year period. Due to the e

8. Impact of artificial lighting on the ecosystem / Influência da iluminação artificial sobre a vida silvestre: técnicas para minimizar os impactos, com especial enfoque sobre os insetos
The impact of light pollution on man and on the ecosystem is a rising concern among ecologists however, in the same time the human population is demanding more lighting for safety and comfort. In order to satisfy human lighting needs with a minimum impact on the ecosystem, manly on insects, we tested commercial equipments using different types of lights and

9. An analysis of surface fluxes and of the microclimate on cerrado, sugarcane and eucalyptus: implications for regional climate changes / Uma análise dos fluxos de superfície e do microclima sobre cerrado, cana-de-açúcar e eucalipto, com implicações para mudanças climáticas regionais
This work investigates potential regional scale temperature and precipitation changes in the São Paulo state, caused by land use changes. We analised micrometeorological measurements, in the period February 2005 to February 2006, over three different ecosystems (cerrado, sugar cane and eucalyptus plantation). The surface energy balances showed that over the

10. Modelagem do balanço de energia do dossel da cultura do pimentão em casa de vegetação. / Canopy energy balance modeling of sweet pepper cultivated in greenhouse.
In a greenhouse production system, the canopy of culture is the main element that modifies the internal microclimate. Its comprehension is very important to understand the energy exchange process. Due to the complexity interaction among several elements, the modeling represents an important tool for research in protected environments, but little used in Braz

11. Characterization of the rain station in the south and southeastern regions of Brazil associated with the atmospheric circulation / Caracterização da estação chuvosa nas regiões sul e sudeste do Brasil associado com a circulação atmosférica
Neste trabalho foi estudados o início e fim da estação chuvosa através de climatologia pêntadal para as Regiões Sul e Sudeste do Brasil, visando um melhor conhecimento do comportamento do clima e sua variabilidade. Para este estudo foram usados dados diários de precipitação referentes à estações meteorológicas da Agência Nacional de Energia El�

12. Estimativa dos componentes do balanço radiativo à superfície mediante satélites meteorológicos / Estimation of components the budget radiation surface by using meteorological satellites
The budget between incoming radiation surface and outgoing is called Budget Radiation Surface (BRS). Conventional methods of measure of this budget are prompt and therefore representative of small areas, while that the meteorological satellites allow to all have a regular covering of the globe. This thesis has as objective basic to analyze methods of estimat
