13. Efeito da sazonalidade nos níveis de atividade física em adultos
There are no consistent findings about the effect of weather and season changes on the physical activity levels. We conducted a study to evaluate seasonal effects on physical activity levels among adults living in Porto Alegre and metropolitan region, Southern Brazil. The study design was longitudinal with a convenience sample of 120 adults, aged 20 to 69. V

14. Resposta da Plataforma Continental Sudeste a ventos sazonais e sinóticos de verão: estudos numéricos / Response of the South Brazil bight to summer seasonal and synoptic winds: numerical studie
In order to study the pertubations caused on the South Brazil Bigth (SBB) caused by the passage of a cold front during Summer, a mean basic state for currents was obtained using the POM (Princeton Ocean Model) through diagnostic simulation, followed by a short round prognostic. The mean currents modeled are in certain instancies similar to the currents measu

15. Estudo da variabilidade sazonal da profundidade óptica do aerossol em São Paulo a partir de radiômetros MFRSR / Study of the seasonal variability of the aerosol optical depth in São Paulo using MFRSR radiometers.
The evaluation of the aerosol effects to the local and global radiation budget, as well as the impact on human health, particularly in large urban centers, demands knowing accurately their concentration and spatial-temporal distribution. In this context, the accurate long term monitoring from ground based stations installed around the world has become a chal

16. Behavior of dissolved inorganic N in surface and sub-surface waters in a cultivated sugar cane area / Comportamento do N inorgânico dissolvido em águas superficiais e sub-superficiais em área com cultivo de cana-de-açúcar
The sugar cane is an important agricultural activity in Brazil and its productivity is related to several factors, such as the availability of suitable nutrients quantities, with emphasis on the nitrogen. However, the constant use of fertilizers increases the possibility of environmental contamination, mainly in water bodies. In this study were evaluated the

17. Ethanol storage tanks location in Brazil: a mixed integer program model application / Localização de tanques de armazenagem de álcool combustível no Brasil: aplicação de um modelo matemático de otimização
The main purpose of this research is to develop a mathematical model intended for strategic analysis of the optimal location and considering suitable volumes for storage ethanol (anhydrous and hydrous) tanks. The Mixed Integer Program - MIP model was based on Brazilian ethanol distribution system. The model considered market parameters as supply, demand, and

18. Formigas como carreadoras de microrganismos no Hospital Escola da Universidade Federal do Triângulo Mineiro.
Ants have not always been seen as harmful insects and their connection with the possible transport of microorganisms has turned them into an object of study. This study aimed at getting to know the fauna of ants present at Hospital Escola (HE), Universidade Federal do Triângulo Mineiro, Uberaba/MG, and on Campus I. It also focused on the species of microorg

20. Coastal Ocean Response to Alongshore Variations in Topography and Wind Forcing
The effects of alongshore variability in topography (banks and capes) and spatial variability in the wind forcing, including the wind-stress curl, on coastal ocean circulation are studied using a combination of observations and model simulations. Satellite sea surface temperature observations are used to describe the seasonal evolution of temperature fronts

21. Dinâmica Costeira dos Campos petrolíferos Macau/Serra, litoral setentrional do Estado do Rio Grande do Norte
This thesis describes the general behavior of the northern shore of the State of Rio Grande do Norte relating beach profile morphology with hydrodynamic and sedimentological parameters. The Macau and Serra Oil Field are inserted on this area and are under accelerated coastal erosion. At these oil fields are installed oil wells from PETROBRAS, nowadays locate

22. ESTUDO DO MATERIAL PARTICULADO ATMOSFÉRICO E METAIS ASSOCIADOS ÀS PARTÍCULAS TOTAIS EM SUSPENSÃO NA CIDADE DE OURO PRETO, MG
vii SUMMARY Airborne particles and the substances associated in them can cause damages to the human health, flora and fauna, to buildings and particularly monuments. Therefore, knowledge of the levels of these particles in the air is important for the establishment of preventive actions. This work had as an objective to study the particles carried by the air

24. Riscos e gestÃo ambiental no estuÃrio do Rio malcozinhado, Cascavel-CE
The Rio Malcozinhado lagoon-estuarine system is located in the Cascavel municipality, in the Cearà State Southeastern littoral 75km away from Fortaleza, Northeastern Brazil. Its 380 km2 hydrographic basin lies on basement rocks, Plio- Pleistocene Barreiras Formation sediments and Quaternary deposits. The urban expansion of the area in the last two decades w
