1. Efeito indireto dos aerossóis: observações em nuvens amazônicas em atmosfera poluída e na transição para limpa segundo os dados dos programas LBA/SMOCC/ENFIM! E AERONET/NASA. / Indirect effect of aerosols: observations in the Amazon clouds in polluted air and clean transition to the second program data LBA / SMOCC / AT LAST! And AERONET / NASA.
In the Brazilian Amazon, fires occur seasonally. The pollution generated because changes in time weather and climate of the Amazon. Studies have shown that the emission of particulate matter alters the radiative balance via direct effect (Solar radiation scattering and reflection.) and indirect aerosol (Increased concentration droplet and the cloud content l

2. Avaliação de metodologias de caracterização atmosférica na conversão de dados radiométricos digitais em valores físicos
- The conversion of digital numbers (DN) of orbital images to physical quantities of the Earth surface is dependent on a good atmospheric characterization, which has been performed through the use of data collected by meteorological balloons or by sun photometers positioned at the surface. Recently some orbital sensors have generated useful data that can be

3. Estudo das derivas zonais das irregularidades de plasma ionosférico na região brasileira / Study of ionospheric zonal plasma irregularity drifts over brazilian region
A detailed study of the zonal drift velocities of the ionospheric bubbles is carried out using experimental airglow data registered at Cachoeira Paulista (22.50 S, 450 W, dip 300 S)during the period of October to March, between 1980-1994. This study is based upon 172 nights of zonal scanning photometer measurements of OI 630 nm airglow. The zonal velocity ma

4. Estudo das derivas zonais das irregularidades de plasma ionosférico na região brasileira / Study of ionospheric zonal plasma irregularity drifts over brazilian region
Esta dissertação apresenta um estudo detalhado do comportamento das velocidades de derivas zonais das bolhas ionosféricas detectadas em Cachoeira Paulista (22o 48 S, 45o 00 O, dip 30o S)nos meses de outubro à março entre 1980-1994. Tal estudo baseia-se em 172 noites de ocorrência das bolhas ionosféricas sobre aquela região, registradas por observaç�

5. Evaluation of two photometers used in enzyme-linked immunosorbent assays.
The performance of two commercially available high-speed photometers, designed for through-the-plate reading, was evaluated. Linearity of instrumental reading and reproducibility of same-day and 2-day measurements were assessed by least-squares analysis and analysis of variance, respectively. For both instruments, the photometric error was on the order of th
