Exterior shading devices and outdoor units can be closely coupled since these two building components are commonly installed next to each other. This study uses a EnergyPlus-Fluent modeling approach examine how combination of exterior heat rejection from affect the ambient environment building, changes in influence cooling loads indoor PM2.5 exposure. Three were simulated, including horizontal ...

in this paper, the removal of phenol by using aqueous solution in a low pressure reverse osmosis membrane was investigated. the effect of feed pressure, feed concentration, feed flow rate and feed ph on phenol rejection was investigated. the results showed that feed ph is the most affective parameter on the phenol rejection. rejection of phenol increased with increasing ph from 2 to 10 under th...

We develop a new efficient simulation scheme for sampling two families of tilted stable distributions: exponential (ETS) and gamma (GTS) distributions. Our is based on two-dimensional single rejection. For the ETS family, its complexity uniformly bounded over all ranges parameters. This algorithm outperforms existing schemes. In particular, it more than well-known double rejection scheme, which...

purpose: to investigate the efficacy of topical cyclosporine a 2% in treating and preventing recurrent graft rejection episodes after penetrating keratoplasty (pkp) in patients with history of previous rejection episodes. methods: in this clinical trial, eligible pkp patients were randomly given topical cyclosporine a 2% or placebo in addition to a standard corticosteroid regimen for an episode...

This paper proposes an approach for improving the plant efficiency by reducing the heat rejection temperature of power cycle using Kalina Cycle System 11 (KCS11) which is integrated at the steam condenser of a 500 MWe SubC (subcritical) coal-fired power plant. It is modelled by using power plant simulation software ‘Cycle Tempo’ at different plant operating conditions. Results show t...

direct contact membrane distillation (dcmd) which emerges as an alternative separation technology can effectively perform a colloidal separation process under thermal driven force. dcmd is capable of extracting pure water from aqueous solutions containing non-volatile nanoparticles through the hydrophobic microporous membrane when a vapour pressure difference was established across the membrane...

the effect of membrane molecular weight cut off (mwco) at three levels (10, 20 & 50 kd) on dynamic behavior of permeate flux (jp), hydraulic resistances (total hydraulic resistance, rt; reversible fouling resistance, rrf; irreversible fouling resistance, rif and membrane hydraulic resistance, rm) and milk solutes rejection (protein, rp; fat, rf; lactose, rl; minerals, rm and total solids, r...

the effects of three levels of transmembrane pressure (1.0, 1.5 and 2.0 mpa) as well as three temperature  levels of: 30, 40 and 50°c on the efficiency of nanofiltration process of waste brine from the regeneration of ion exchange resins at sugar industry (to recover water and sodium chloride) were investigated throughout the current study. the polyamide tubular afc40 membrane manufactured by p...

Background: Correlations between bone marrow, heart, kidney, liver, skin and lung transplant rejection or survival with human cytokine gene polymorphisms have been described. There are also reports about the role of cytokines and Tumor Necrosis Factors-Alpha (TNF-α) on corneal transplant in animal models. Further studies are needed to clarify the role of cytokines in corneal allograft rejection...
