1. Multi-stage dumping sequence - a feasible waste management alternative for open pit mining
Abstract Waste management and environmental aspects are progressively gathering attention in the mining industry. Mine planners must deal with increasingly complex tasks to balance between ore block schedules, waste disposal, operational cost and environmental reclamation. The mine incomes are generally related to mining and processing of the ore, thus most

2. Suficiência amostral para avaliação da fauna epiedáfica com o método Provid
Resumo O solo é habitado por milhares de organismos responsáveis por diversas funções e processos no ecossistema. Por apresentar uma grande sensibilidade às modificações do meio, a fauna do solo é considerada um bom bioindicador de qualidade do solo. Entretanto, uma amostragem inadequada pode inviabilizar sua utilização em estudos de impacto ambien

3. Technical contributions to territorial planning and the use of ecosystemic services in a hydrographic basin with a water deficit in the Atlantic Rainforest of Brazil
Resumo A bacia do rio Dois Rios (R2R) (3.159 km²) recolhe os efeitos climáticos e ambientais típicos de zonas situadas a sotavento de cadeias montanhosas. Tem balanço hídrico deficitário, havendo poucos e específicos locais úmidos. Este estudo identifica, espacializa, caracteriza e agrupa as planícies de inundação com maior habilidade em produzir

4. A methodological proposal for the recovery of palynomorphs from snow and ice samples
ABSTRACT The procedures for a set of techniques to recover grains of pollen 26 and spores from liquid samples are described. Liquefied samples of matrices, such as melting lakes, snow and ice, can provide a record of climatic and environmental events at different geographic and temporal scales. The need for standardization of techniques was demonstrated in r

5. Environmental severity promotes phylogenetic clustering in campo rupestre vegetation
The stress-dominance hypothesis postulates that the importance of competition in plant communities declines with increasing environmental stress while the importance of environmental filters increases. To test this hypothesis for campo rupestre vegetation, we analyzed phylogenetic diversity and community structure of angiosperm communities at two study sites

6. Caracterização da comunidade de mamíferos de médio e grande porte em paisagem agrícola fragmentada / Characterization of the mid and large bodied mammal community in a fragmented agricultural landscape
Agricultural expansion is a major cause of habitat fragmentation, leading to a reduction and isolation of natural areas. It is therefore important to understand the role of agricultural landscape structure and dynamics in maintaining local biodiversity. We aimed to describe how the structure and dynamics of an agricultural landscape influenced the community

7. Análise integrada do uso e aptidão agrícola dos solos na Amazônia Legal visando o desenvolvimento sustentável
Encroachment of the agricultural frontier over the Brazilian Amazon (Amazônia Legal) forest and savanna (cerrado) areas generates an array of negative environmental impacts, such as deforestation and fires. The conflict between the pressing agricultural front, mainly represented by cattle and soya productions, and the preservation of such forest and cerrado

8. Environmental and genetic variation of isoflavone content of soybean seeds grown in Brazil.
Abstract ? The objective of this work was to evaluate isoflavone concentrations in seeds of different Brazilian soybean cultivars grown in a range of locations and environmental conditions in Brazil. Seeds of 233 cultivars grown in Ponta Grossa, PR, Brazil, during the 2001/2002 soybean season, and of 22 cultivars sown in different locations of Brazilian Nort

9. A integração da sustentabilidade às práticas de controle gerencial das empresas no Brasil / The integration of sustainability into management control practices in Brazil
The study aims to map and analyse the integration of sustainability into the management control (MC) practices of companies in Brazil. Sustainability was represented by the economic, envinronmental and social dimensions of the triple bottom line approach (ELKINGTON, 1997), and management control was addressed by the levers of controlmanagement control model

10. Identificação e caracterização de genes codificantes de proteínas ricas em glicina ligantes de RNA em soja (Glycine max (L.) Merril)
Molecular information on plant developmental process, as well as detailed knowledge of the interaction between stress conditions and plant response to environmental factors are essential for understanding the adaptive response. Glycine-Rich Proteins (GRP) have the amino acid glycine well represented in their primary structure. The genes encoding GRPs are dev

11. Detecção do virus da diarréia bovina em carrapatos Rhipicephalus (boophilus) microplus alimentados em bovino persistentemente infectado
Background: Bovine viral diarrhea virus (BVDV) is one of the main agents that cause economical losses in cattle worldwide. Congenitally infected calves that are born persistently infected (PI) to BVDV are the main sources of infection to susceptible cattle. Direct contact is the most important form of transmission, but indirect contact can also spread BVDV,
