1. MODELOS FOTOQUÍMICOS SIMPLES COMO FERRAMENTA PARA O GERENCIAMENTO DA QUALIDADE DO AR
Atmospheric processes in an urban scenario are very complex and depend on meteorological parameters, emission, transport and deposition processes and the chemical mechanism. Simple air quality models can be used to understand the main aspects of ozone formation and provide information to adopt pollution control strategies. In this work the detailed simulatio

2. Viscosities and viscosity deviations of binary mixtures of biodiesel + petrodiesel (or n-hexadecane) at different temperatures
Viscosities of four binaries mixtures [soybean biodiesel + diesel oil (or n-hexadecane) and coconut biodiesel + diesel oil (or n-hexadecane)] have been determined at T = (293.15, 313.15, 333.15, 353.15, 373.15) K and atmospheric pressure over the entire composition range. Experimental data were fitted to the Andrade equation and the adjustable parameters and

3. Estimativa de áreas queimadas com produtos modis como subsídio à estimativa de emissões de gases de efeito estufa pela queima de biomassa na Amazônia e Cerrado Brasileiros / Burned area estimation using MODIS fire products as a subsidy for greenhouse gases emissions estimation due biomass burning in the Brazilian Amazon and Cerrado.
At present, the estimates of parameters used in global emissions models are based on low and moderate spatial resolution satellite data, and even though those was an advanced since the rising of the first orbital platforms, it is still necessary to reduce the uncertainty of these estimates. This improvement depends basically, on the capacity of the scientifi

4. Modelling and measurements of illuminance for diverse atmospheric conditions in the northeast of Brazil / Medidas e modelagem da iluminÃncia para diversas condiÃÃes de cÃu no Nordeste do Brasil
In Brazil, and particularly in the Northeast region, illuminance measurements are not a part of the routine measurements in meteorological stations. Therefore, the availability of information on illuminance is rarer than the measurements carried out on solar irradiation. In this context, two stations for measuring illuminance and solar irradiation were insta

5. INVERSE PROBLEM IN ATMOSPHERIC PHISICS / PROBLEMAS INVERSOS EM FÍSICA DA ATMOSFERA
Techniques for estimating unknown terms - such as eddy diffusivity and counter-gradient - in atmospheric flow are presented in this study. The methos is also used to identify the source term in atmospheric pollution. The scheme adopted is based on inverse problem methodology. The inverse problem is formulated as a non-linear optimization problem, where the o

6. Oxidação umida catalitica da lignina em reatores trifasicos com produção de aldeidos aromaticos
The lignocellulosic material, representing the largest natural renewable resource, occurring in the plants under the cellulose form, hemicellulose, lignin and extractive, with the lignina corresponding about 30% of this total one. The routes of lignin chemical processing, with prominence for the oxidations processes, with the objective of vanilin production,

7. Estimativa de emissividade da superficie continental a partir de dados de satelite em microondas / Microwave land surface emissivities estimated from SSM/I observations
Microwave emissivities of land surface were estimated from the Special Sensor Microwave/Imager (SSM/I) observations using the 19 and 85 GHz channels, and surface skin temperature data derived from the Tiros Operacional Vertical Sounder (TOVS). The atmospheric contribution was calculated from simulations of the Atmospheric Transmission at Millimetric and subm
