1. Grazing management under integrated crop-livestock system on physical soil attributes and grain yield soybean
ABSTRACT Integrated crop-livestock system (ICLS) can help improve the soil physical attributes, increasing the nutrients cycling and yield potential. We evaluated the effect of forage height management under ICLS on physical soil attributes and water infiltration. Field experiment was carried out for two consecutive years in a randomized complete block desig

3. Sediment production and soil water infiltration under different simulated rainfall characteristics
RESUMO O estudo foi realizado com objetivo de avaliar a produção de sedimentos, a infiltração da água e o escoamento superficial em um Argissolo Vermelho-Amarelo sob chuvas simuladas com erosividades semelhantes, mas com distintas combinações de intensidade de precipitação (Int) e duração (Dur). As chuvas foram aplicadas após o preparo do solo e

4. Path coefficient analysis, a different approach to identify soil quality indicators
RESUMO Os indicadores de qualidade do solo relacionados à redução da erosão hídrica podem auxiliar no correto manejo do solo. Com o auxílio da análise de trilha, objetivou-se com a pesquisa identificar algumas variáveis que possam ser utilizadas como indicadores de qualidade do solo relacionados à redução da erosão hídrica. A pesquisa foi realiz

5. Surface sealing and water erosion of soils with mulching in the semi-arid region of Brazil
RESUMO A avaliação do processo de selamento superficial em solos da região semiárida Brasileira é de grande relevância para compreensão do processo e tomada de medidas mitigatórias. Objetivou-se avaliar o selamento superficial e características físico-hídricas dos principais solos da Bacia Representativa do Alto Ipanema, Pesqueira-PE, sob influên

6. The recent similarity hypotheses to describe water infiltration into homogeneous soils
ABSTRACT A similarity hypothesis recently presented to describe horizontal infiltration into homogeneous soils, developed for coarse-textured soils like sieved marine sand, implies that the soil water retention function θ(h) is the mirror image of an extended Boltzmann transform function θ(λ2). A second hypothesis applicable to vertical infiltration sugge

7. Observations of the effects of different chemical blowing agents on the degradation of poly(lactic acid) foams in simulated soil
This work examined the influence of different chemical blowing agents (CBA), one endothermic and one exothermic, at the same concentration (2% by mass), on poly(acid lactic), PLA foams. The CBA was incorporated into the PLA in a single-screw extruder, and the foams were expanded by heating in an electric oven under free pressure conditions. Foam degradation

8. ATRIBUTOS DO SOLO E DESEMPENHO DA CULTURA DO MILHO SOB DIFERENTES ALTURAS DE MASSA DE FORRAGEM PÓSPASTEJO / SOIL ATTRIBUTES AND CORN DEVELOPMENT UNDER DIFFERENT HEIGHTS OF FORAGE POST-GRAZING
The Crop-Livestock System (ILP) refers to an association between two activities in the same area at different periods of the year, that involves annual crops and livestock. This study aimed to: (a) evaluate the dry matter yield and residual dry matter remaining of winter intercrop forage (oat, rye and vetch) under different heights of post-grazing residue, (

9. Nefropatia crônica por ciclosporina : papel do ácido úrico e do sistema renina angiotensina aldosterona como mediadores de disfunção endotelial, inflamação e vasculopatia / Cyclosporine nephropathy : effect of uric acid and the renin angiotensin aldosterone system as mediators of endothelial dysfunction, inflammation vasculopathy
Chronic allograft nephropathy is characterized by stripped tubular atrophy and interstitial fibrosis, in presence of arteriolar hyalinosis, resembling an ischemic pattern of chronic kidney disease. Chronic ischemia is associated with reduced glomerular filtration rate, and increase in serum uric acid levels. Cyclosporine per se also has a direct effect on tu

10. Comportamento hidrodinâmico e cinético dos reatores anaeróbios compartimentado (RAC) e manta de lodo (UASB) operados em série / The hydrodynamic and kinetic bahavior of the anaerobic baffled reactor (ABR) and upflow anaerobic Sludge blanket (UASB) operated in serie
The aim of this research was to determine the hidrodymanic and kinetics behavior of a pilot system plant, treating swine liquid effluent, installed in the Zootechnical Department of the Federal University of Lavras. The pilot system was composed by several units working in series, such as sand retention box (SRB), static sieve (SS), acidification and equaliz

11. Improvement of properties, and water and clay movement in vertisol-amended sand columns.
Clay amendments may improve agricultural productivity of sandy soils by increasing nutrient-and water-holding capacities. The objective of this research was to determine the effect of Vertisol amendments on infiltration rate, available water capacity, cation exchange capacity, and clay and carbon migration in sandy soil colums. Acid-washed quartz sand was pa

12. Procedimento para estimativa da intensidade de precipitação máxima admissível em pivô-central com base nas características do equipamento e do solo.
ABSTRACT: A procedure to estimate the center pivot maximum application rate, based on equipment and soil characteristic is presented. It was developed to minimize the surface runoff. To achieve this objective, the Green and Ampt (GA) infiltration equation was modified to include surface sealing and surface storage. The highest application rate is determined
