1. Geological modeling of a stratified deposit with CAD-Based solid model automation
Abstract The planning stages of mining activities require many comprehensive and detailed analyses. Determining the correct orebody model is the first stage and one of the most important. Three-dimensional solid modeling is one of the significant methods that can examine the position and shape of the ore deposit. Although there are many different types of mi

4. Registros palinológicos inéditos nas formações Teresina e Rio do Rasto (Permiano, Grupo Passa Dois, Bacia do Paraná): implicações biocronoestratigráficas e paleoambientais
The Pennsylvanian-Permian interval of the Paraná Basin is relatively well-known on its palynological content. However, little has been published from the Permian Serra Alta, Teresina and lower Rio do Rasto formations (Passa Dois Group). A total of thirty seven core samples were collected along a vertical range of 600 meters of these units in two boreholes i

5. Investigação ambiental em posto de abastecimento de combustiveis no municipio de Seropedica - RJ / Environmental survey of a Seropedica city gas station, Rio de Janeiro State, Brazil
Gas stations create a recognized potential threat of contamination to soil, groundwater and air. Brazilian environmental laws regulate the technical standards regarding the installation, equipaments and operation of gas stations in addition to requiring environrnental licenses. Accidents may expose the population to toxic and flammable substances. In Seropé

8. Mechanical behavior of urban solid waste / Comportamento mecânico de resíduos sólidos urbanos
This thesis deals with the mechanical behavior of urban solid waste from Bandeirantes sanitary landfill (São Paulo, Brazil). Field and laboratory tests, as well as data from field instrumentation (settlement) were obtained and used in the analysis. Results of in situ tests such as standard penetration test (SPT), cone penetration test (CPT), infiltration te

12. Vertical and Horizontal Variations in the Physiological Diversity of the Aerobic Chemoheterotrophic Bacterial Microflora in Deep Southeast Coastal Plain Subsurface Sediments
Aerobic chemoheterotrophic bacteria were isolated from surface soils and coastal plain subsurface (including deep aquifer) sediments (depths to 265 m) at a study site near Aiken, S.C., by plating on concentrated and dilute media. Morphologically distinct colonies were purified, and their responses to 21 selected physiological tests were determined. These iso
