The development of thin-film composite membranes has gained more importance as they exhibit higher permeability, solute rejection and improved antifouling behavior. incorporation hydrophilic nanomaterials within the thin film reported to effectively increase hydrophilicity improve membrane performance. In this study novel nanofiltration were prepared by interfacial polymerization trimesoyl chlo...

BACKGROUND Preeclampsia has been associated with several risk factors and events. However, it still deserves further investigation, considering the multitude of related factors that affect different populations. OBJECTIVE To evaluate the maternal factors and adverse perinatal outcomes in a cohort of pregnant women with preeclampsia receiving care in the public health network of the city of Ma...

The deterioration of soil physical properties had led to a decrease in soil–water availability facility agriculture. Thus, an experiment was set up with five treatments 0% (CK, No additives), 3% biochar (BA3, Mass ratio), earthworm manure (QA3), 5% (BA5), and (QA5) investigate the effects on hydraulic characteristics under greenhouse conditions. including bulk density (BD) total porosity (TP) w...

OBJECTIVES We compared the hemodynamic effects of dobutamine and enoximone administration before and after long-term beta-blocker therapy with metoprolol or carvedilol in patients with chronic heart failure (HF). BACKGROUND Patients with HF on beta-blocker therapy may need hemodynamic support with inotropic agents, and the hemodynamic response may be influenced by both the inotropic agent and t...

In order to achieve a better software quality, it is an interesting aspect to verify the correctness of a program at the source code level with respect to a given specification. We are currently developing an interactive verification system called Jive [7] which operates on a Java subset using a Hoare-style programming logic. It is very tedious to verify each and every line of the code to be ex...

We propose a priority-pricing scheme for zonal access to the electric power grid that is uniform across all buses in a zone. The Independent System Operator (ISO) charges bulk power traders a per unit ex ante transmission access fee. The zonal access fee serves as an access insurance premium that entitles a bulk power trader to either physical injection of one unit of energy or a compensation p...

Abstract The stability of slopes is greatly influenced by seasonal variations in pore water pressures (pwp) induced rainfall infiltration and evapotranspiration processes. Despite that, the prediction hydrological effects long-stem planting often simplified or neglected because it challenging to address. Its computation requires a proper definition plant root uptake spatial distribution, which ...

Knowledge of spatial variation of soil properties is important in precision farming and environmental modelling. Spatial distribution of water content at field capacity (FC) and permanent wilting point (PWP) at different zones of a farm governs the available water for plant growth. These two soil hydraulic parameters play key roles in crop selection for different blocks of a farm, and in schedu...
