Groundwater recharge is one of the basic parameters required in water resources potential calculations. There are several methods applied to estimate groundwater recharge, however, every method has its own advantages and disadvantages, due fact that theory infiltration vadose zone hydrology highly complex. Search for a based on less complex theory, which requires readily available representativ...

In our current study, a newer amine functionalized guar gum derivative was studied for its efficacy in colonic drug delivery. Glycyrrhizic acid mono-ammonium salt was used as the model drug. Drug-loaded microparticles were formulated by ionic crosslinking using sodium tripolyphosphate. The Scanning Electron Microscopic study revealed spherical particles of sizes from 4.9 ± 3.8 μm to 6.9 ± 3.9 μ...

soil hydrau-physical data are important for many hydrological modelings. they are the main variables controllingthe key processes such as water and chemicals movement and transport in the soil profiles. this study was conductedin order to analyze the spatial distribution of selected soil hydrau-physcial characteristics including infiltration rate(ir), saturated hydraulic conductivity (ks), bulk...

the aim of this research was to study the wear behavior of 42crmo4 steel/zro2 composite with 10 and 30 ppi performed ceramic and compare it with the un-reinforced steel under different applied loads. the composite specimens were obtained by pressureless infiltration of the melt into a preformed ceramic of zirconium oxide. the effect of applied load on the specimens wear behavior was studied by ...

the purpose of this work was to test the efficiency of the treatment of wastewater by infiltrationunder laboratory conditions, to remove bacterial and organic load and to convert it to available nutrient for crop plants. in order to achieve this objective, polyvinyl chloride (pvc) columns of 133 cm of height were used. the columns were filled with sand and/or pozzolana and loaded with municipal...

Despite its wide application across arid land types, furrow irrigation is often associated with numerous environmental problems related to deep percolation, runoff, and soil erosion. In this study, a straightforward approach was proposed achieve higher uniformity reduce Here, the impacts that moveable “plug” has on behavior of water in were simulated using FLOW-3D HYDRUS-2D, where three plug he...

Many different equations have been proposed to describe quantitatively one-dimensional soil water infiltration. The unknown coefficients of these characterize hydraulic properties and may be estimated from a n record, { t ∼ i , I } = 1 $\{ {\tilde t_i},{\tilde I_i}\} _{i 1}^n$ cumulative infiltration measurements using curve fitting techniques. two-term equation, ( ) S + c K s $I(t) S\sqrt c{K_...
