1. Estoque e perda de necromassa da vegetação lenhosa em um gradiente fitofisionômico na transição Amazônia-Cerrado
Resumo A necromassa é um importante componente da decomposição e ciclagem de nutrientes nos ecossistemas naturais. Nosso objetivo foi avaliar o estoque e perda de necromassa da comunidade e das espécies em um gradiente fitofisionômico de cerrado típico, cerradão e floresta estacional semidecidual, na transição Amazônia-Cerrado. Calculamos, para cad

2. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

3. Beneficial Effects of Ethyl-Cyanoacrylate Coating Against Candida Albicans Biofilm Formation
Resumo O objetivo deste estudo foi verificar se as modificações feitas com o adesivo etil cianoacrilato, ECA (Super Bonder ®, Loctite, Itapevi, SP, Brasil) sobre as resinas acrílicas para reembasamento, poderiam inibir ou reduzir a formação de biofilmes de C.albicans sobre sua superfície quando comparado com um selante de superfície comercial (BisCov

4. Heterogeneous Microtubules of Self-assembled Silver and Gold Nanoparticles Using Alive Biotemplates
Microtubules were constructed by covering the fungus Aspergillus aculeatus sequentially with silver and gold nanoparticles, resulting in a stable hybrid mesostructured material that presented three distinct regions containing different combinations of silver and gold nanoparticles. These heterogeneities were determined by the hyphal growth since the impossib

5. Avaliacao de modelos para previsao da infiltracao de agua em solos sob cerrado.
Os objetivos deste trabalho foram testar sob condicoes de solo nu e com cobertura vegetal morta o modelo de GAML,e apresentar a ideia de velocidade de infiltracao basica variavel em funcao da energia cinetica das chuvas, a ser aplicada no modelo original de Green-Ampt no caso de solo nu. Usaram-se dez infiltrometros e um simulador de chuvas, instalados em La

6. Efeitos dos sistemas de pastejo isolado, simultâneo e alternado de ovinos com bovinos sobre as características da forragem, desempenho, consumo e características de carcaça dos ovinos / Effect of isolated; simultaneous and alternated pasture of sheep and cattle on pasture quality; performance; intake and carcass traits of sheep
The aim of this study was to evaluate the effects of three types of rotational pasture: isolated (I); simultaneous (S); and alternated (A) with sheep and cattle on structural and chemical traits of grass, voluntary dry matter intake, animal performance and carcass traits of sheep. The experimental period lasted 99 days. A experimental area of Panicum maximum

7. Distribuição espacial de ferro, cobre e chumbo em sedimentos de manguezal em um gradiente de degradação na Baía de Guanabara (Estado do Rio de Janeiro)
Iron, copper and lead distribution was evaluated in sediment cores from a disturbed mangrove area in Guanabara Bay: a core from a seaward site where mangrove vegetation was removed ~20 yr before sampling (MD); a core from an intermediate site with dead vegetation, apparently due to insect attack (MP), and a core from a landward site with living vegetation (M

8. Variabilidade espacial de propriedades físicas e químicas de um neossolo flúvico cultivado com cenoura irrigada com água moderamente salina
An experiment has been performed aiming to evaluate the spatial-time variation patterns of soil humidity in an irrigated area in Pesqueira PE. The experiment has been carried out in an irrigated plot with carrot, with duration of 96 days. Two irrigated sectors (1 and 2) with 900 m2 each (30 m x 30 m) have been monitored in the experiment, using microsprinkle

9. As dinâmicas de Schefflera angustissima (March.) Frodin (Araliaceae) e de Andira anthelmia (Vell.) March. (Fabaceae) na reserva de Morro Grande, São Paulo. / The dynamics of Schefflera angustissima (March.) Frodin (Araliaceae) and Andira anthelmia (Vell.) March. (Fabaceae) in the Morro Grande reserve, São Paulo.
Population dynamics deals with variation in time and space in the density and abundance of populations. The studies about the dynamics of tropical rain forest tree species, in particular, have become popular only about 1970, when the extinction risks for species of economic interest became pressing. Because the Brazilian biomes are being destroyed progressiv

10. Cosmologia e praticas rituais Kaingang
This thesis aims at understanding Kaingang cosmology by studing three rituais: the Kuiâ (shaman) Celebration, the Kikikoi Festival, and the Widowed Person s Purification Ritual. These three rituais symbolize different times which I called the three times o, the world, taking in to account the fact that the Kaingang cosmology rests on cycles of earth conflag

11. In Vitro Phagocytosis and Intracellular Fate of Variously Encapsulated Strains of Cryptococcus neoformans
Five isolates of Cryptococcus neoformans type A with stable capsular thicknesses were used. Three of the isolates had capsules of medium size, one had a minimal capsule, and the other, a large capsule. Peritoneal exudate cells from Lewis rats were cultured on cover slips in Leighton tubes containing medium 199 and 20% fresh, isologous normal rat serum. Yeast
