1. Prototypes and modulation functions of classical and novel configurations of optical chopper wheels
Optical choppers with rotating wheels are some of the most used macroscopic optomechatronic devices for the controlled modulation, attenuation or obscuration of light in a wide area of applications. We discuss and compare the modulation functions produced by two types of chopper wheels: the classical device, with windows with linear edges, and the eclipse ch

2. Desenvolvimento de metodologia em SIG para zoneamento ecológico: estudo de caso da Bacia Ribeirão do Gama-DF.
ABSTRACT: The permanent preservation areas were created to protect the environment, decreasing processes as erosion often caused by anthropic interferences. The Brazilian Forest Law stablished criteria to the delimitation of these areas. An area zoning presents special areas where permanent preservation areas are inclued. This way, in the present paper was p

3. VALORAÇÃO AMBIENTAL DA EROSÃO MARGINAL DO PERÍMETRO IRRIGADO COTINGUIBA / PINDOBA NO BAIXO SÃO FRANCISCO SERGIPANO. / ENVIRONMENTAL VALUATION OF EROSION OF MARGINAL PERIMETER IRRIGATED COTINGUIBA / PINDOBA DOWN IN SAN FRANCISCO SERGIPE.
A acelerada erosão das margens no Baixo curso do rio São Francisco é fruto das ações antrópicas e das políticas de desenvolvimento voltadas para construção e operação de barragens e geração de energia. Este trabalho teve como objetivo a aplicação do método custo de oportunidade para mostrar que o investimento em recuperação ambiental é eco

4. A planície aluvial do médio rio araguaia: processos geomorfológicos e suas implicações ambientais / The alluvial plain of the middle Araguaia River: geomorphological processes and their environmental implications
The Araguaia River is the most important fluvial system of South America. With an area of 380.000Km, its includes two phytogeography regions that have a good part of planet biodiversity: Cerrado, in the south, and Amazonia Forest, in the north of Brazil. The high level of Cerrado ecosystem destruction and changes in the land using, after 1965, promoted an in

5. Growing fractures of the skull.
Tne cases of growing fractures seen in the last 10 years are presented. Six of the patients sustained their injury within the first six months of life. The defects formed rapidly, several within two or three months after injury. There was enlargement of the defect in only one case after the date of discovery. Although the defects involved the parietal bone m
