Permeable surfaces are increasingly rare in urban centers, but they have the utmost importance for stormwater infiltration. In this context, green spaces key to reducing problems caused by runoff. This work aimed evaluate physical characteristics of soil used agroecological gardening, comparison with parks, wasteland, and riparian forest Sorocaba, São Paulo, Brazil. During one-year data collect...

study of soil quality indicators were considered as a useful method in the land use management. changing the land use affect soil hydrological processes such as water infiltration process. spatial variation of water infiltration in soil plays a very important role in hydrologic processes. variability of this process is affected by the inherent and non-inherent characters of the lands. in order ...

Thioredoxin (TRX) is a multifunctional redox (reduction/oxidation)-active protein that scavenges reactive oxygen species by itself or together with TRX-dependent peroxiredoxin. TRX also has chemotaxis-modulating functions and suppresses leukocyte infiltration into sites of inflammation. Leukocyte infiltration and oxidative stress may be involved in the pathogenesis of several diseases, includin...

infiltration is a complex process that changed by initial moisture and water head on the soil surface. the main objective of this study was to estimate the coefficients of infiltration equations, kostiakov-lewis, philip and horton, and evaluate the sensitivity of these equations and their coefficients under various initial conditions (initial moisture soil) and boundary (water head on soil surf...

plant cover is one of the most important factors affecting infiltration rate of water into the soil and decreasing runoff. distribution of plants in arid and semi-arid areas is almost patchy and form different patterns. one of the fascinating patterns is ring-shaped growth pattern. ring patterns of varying size are formed by clonally reproducing grasses, sedges and even shrubs growing in resour...

A process is described which involves infiltration of aluminum nitrate into partially sintered (porous) zircon bodies. Infiltration kinetics were studied using infiltration curves with two distinct regions. The final infiltrated samples were sintered at 1600 °C for 2 h and yielded specimens containing the tetragonal zirconia.The experimental results show that in spite of the similar porosity of...

In this research, infiltration behavior of W-Ag composite compacts with Nickel and Cobalt as additives has been investigated. Nickel and Cobalt were added to Tungsten powder by two distinct methods: mixing elementally and reduction of salt solution. The coated Tungsten powders were compacted under controlled pressures to make porous skeleton with 32-37 vol. % porosity. Infiltration process was ...
