2. Enzyme complex supplementation in different nutrient levels diets on pigs feces excretion and anaerobic digestion
ABSTRACT This research aimed to evaluate enzyme supplementation in diets with different nutritional levels for pigs in their feces excretion and anaerobic digestion. Fifty four gilts were placed on diets formulated to achieve 100 or 95 or 90 % of a pig's nutrient requirements, with the addition of an enzyme complex containing amylase, β-glucanase, cellulase

6. Caracterização mineralógica e da matéria orgânica do solo por técnicas espectroscópicas e DRX
Organic matter is the main agent present in the soil due to some of its actions, for example: responsible by source of nutrient for the plants, avoid erosive process, improve the aggregates stability, and act as a drain to atmospheric CO2, among others. Therefore, there are same management practice to enforce an increase in the percentage of soil organic mat

7. tropical soils, bentonite, hydraulic conductivity, compatibility, barriers. / CONDUTIVIDADE HIDRÁULICA E COMPATIBILIDADE EM COMBINAÇÕES DE SOLO TROPICAL E BENTONITA PARA USO EM BARREIRAS
Barriers are key elements for the environmental protection in waste disposal sites. Additionally, compacted tropical soils have great potential to be used in these barriers, once some technical matters are correctly addressed, including low hydraulic conductivity and adequate compatibility to the disposed fluids. In this context, the bentonite addition in tr

8. The environment in the legal discourse of urban public policy in the state of Mato Grosso - Brazil / O ambiente no discurso juridico da politica publica urbana no estado de Mato Grosso
In this study, we aimed at understanding how the environment can mean in the discourse of public policies in the cities of Cuiabá, Cáceres, Pocone in Mato Grosso, Brazil. We believe that the fact of the city is being located in the Pantanal, which is considered the "National Heritage"; it is in a discursive position in which the environment is urging for t

9. História paleoambiental neopleistocena-holocena, do médio Vale do Rio Paraíba do Sul, Estado de São Paulo: com base na análise da palinoflora.
This paper is about palynological studies realized at Paraíba do Sul river floodplain, in São Paulo. The hole made by vibro-core reached 390 cm depth. The core showed two very similar sedimentation cycles represented by sand in the basis, followed by clay and peat on the top. Besides, the second sequence presents one clay layer on the peat. The first seque

10. Prácticas culturales para el manejo de la Sigatoka negra en bananos y plátanos
Black sigatoka (Mycosphaerella fijiensis) control consists in the continuous use of fungicide sprays and cultural practices. Cultural control reduces inoculum sources of the pathogen and favorable environmental conditions for its development, as well as it increases the vigor of the plants. In order to manage the disease it is necessary to know its behavior

11. Caracterização comparativa do esmalte de dentes decíduos e permanentes por Espectroscopia Raman
The aim of this study was the characterization of primary and permanent teeth enamel, producing comparison parameters to future studies. The Raman spectroscopy identifies the content of organic and inorganic matters through polarized change associated with molecule vibration modes. Third permanent (n=15) and second primary molars (n=15) were used. Samples we
