1. Imaginario de estudantes de Biologia sobre as interações entre ciencia, tecnologia, sociedade e ambiente no contexto de uma disciplina de Geologia / The imaginaries of Biology students on the interactions between science, technology, society and the environment in a Geology class
This work seeks to understand how Biology licentiate students of a Brazilian public university produced meanings about on the interactions between science, technology, society and the environment in the context of a Geology class, as well as which ideas were developed and in which terms field activities carried out might be considered approximations to a STS

2. Evolução tectono-estratigráfica e paleoclimática da formação maricá (Escudo Sul-Rio-Grandense, Brasil) : um exercício de geologia histórica e análise integrada de uma bacia sedimentar neoproterozóica
Significant improvement in the knowledge concerning the Neoproterozoic Maricá Formation of the Sul-riograndense Shield, southern Brazil, was obtained in the latest years. This contribution synthesizes recent data obtained though an integrated analysis of the lowermost unit of the “Camaquã Basin”. Stratigraphic and paleocurrent analyses, petrography, Sr

4. Estudo da variabilidade da piezometria dos aqüíferos freáticos na bacia do alto Rio Jardim - Distrito Federal
The objective of the present work is to increase the knowledge about the variability of the water table in porous shallow aquifer systems. The study area was the Rio Jardim watershed, situated in the southeast portion of the Federal District (Brazil) and characterized by intense agriculture use. The development of the research was based on monitoring wells w

5. Avaliação de impactos ambientais nos tributários do lago Paranoá, Brasília - DF
The high level of urbanization in Distrito Federal in Brazil is contributing to modify the environment particularly the quality of surface water resources. The historical of environment aggression to the Paranoá Lake through urban expansion, land use and land occupation, is studied as environmental changes. In this work, physical-chemistry conditions and ge

6. Cerrado assemblages of reptiles and amphibians along the drainage of Rio Tocantins and the impact of hydroelectric power plants on their conservation / Assembléias de répteis e anfíbios do Cerrado ao longo da bacia do rio Tocantins e o impacto do aproveitamento hidrelétrico da região na sua conservação
The Cerrado herpetofauna was studied along the basin of the Tocantins river using three distinct and complementary approaches. First, a fast sampling scheme, covering all the studied area, was conducted in 11 sites between the Central Plateau, in the state of Goiás, and the northern portion of the Tocantins depression, at the border of the states of Tocanti

7. INTEGRATED STUDY OF THE ALTO DA BOA VISTA VILLAGE, IN THE NOVA SANTA MARTA AREA, SANTA MARIA CITY/RS SECTOR OF THE SUB-BASIN DRAINED BY AN AFLUENT ON THE RIGHT MARGIN OF THE CADENA STREAM / ESTUDO INTEGRADO DA VILA ALTO DA BOA VISTA NA ÁREA DA NOVA SANTA MARTA, MUNICÍPIO DE SANTA MARIA/RS SETOR DA SUB-BACIA DRENADO POR UM AFLUENTE DA MARGEM DIREITA DO ARROIO CADENA
The present research work is based on the systemic perspective, which understands the environment as a group of interconnected elements exchanging energy and material. Thus, the study area is a sector of the sub-basin drained by an tributary on the right margin of the Cadena stream. Its populations historical, social, economical and cultural aspects were con

8. Una cuestión de escala: sociedad, ambiente, tiempo y territorio
As disciplinary limits become blurred and knowledge fields so distant as history and ecology come closer (paradoxically together with a strong specialization within each of them), the tensions generated when we try to harmonize each field's approach on its object of study are more and more clear. We might summarize those approaches around the subject of scal

9. Praticas de campo em geologia introdutoria : papel das atividades de campo no ensino de fundamentos de geologia do curso de geografia, Universidade Federal de Minas Gerais (UFMG)
Geological field activities are essential tools in the learning process of Geology, specially when teaching is limited to just one geological discipline whose characteristic is to be simultaneously introductory and conclusive (Introductory Geology). The influence that field activities play in the Introductory Geology discipline learning of the IGC-UFMG Geogr

10. O desvendar do grande livro da natureza : as praticas geocientificas no Brasil colonial por meio de um estudo da obra mineralogica e geologica do cientista brasileiro José Vieira Couto, 1798-1805
ln the 80 s there was a movement of renovation in the Latin American science historiography. Since then the science has been seen not as an abstract and universal entity but as a practical activity which takes place in a concrete space and time. Through this new vision Latin American historians started making an inventory of the scientific activities in Lati

12. Complexity, contingency, and criticality.
Complexity originates from the tendency of large dynamical systems to organize themselves into a critical state, with avalanches or "punctuations" of all sizes. In the critical state, events which would otherwise be uncoupled become correlated. The apparent, historical contingency in many sciences, including geology, biology, and economics, finds a natural i
