Experiments were conducted to evaluate the performance of a high grade low heat rejection (LHR) diesel engine with air gap insulated piston, air gap insulated liner and ceramic coated cylinder head [ceramic coating of thickness 500 microns was done on inside portion of cylinder head] with different operating conditions [normal temperature and pre-heated temperature] of crude pongamia oil (CPO) ...

Nitrile butadiene rubber (NBR) latex/graphene oxide (GO) membranes were fabricated through a latex compounding and curing method which is relatively new to produce for wastewater treatment. Hence, the steps in production of membrane this approach need be evaluated optimize performance membrane. In paper, effect sulfur loading range 0.5 1.5 parts per hundred (phr) on morphology, crosslink densit...

   In this study, linearized transport pore model (LTPM) is applied for modeling nanofiltration (NF) membrane separation process. This modeling approach is based on the modified extended Nernst-Planck equation enhanced by Debye-Huckel theory to take into account the variations of activity coefficient especially at high salt concentrations. Rejection of single-salt (NaCl) electrolyte is inve...

background: the innate immunity plays an important role in the host response to transplantation by toll-like receptors and results in development of acute allograft rejection. the aim of this study was to evaluate the association of tlr2 and cd14 (co-receptor) gene polymorphisms with acute rejection in kidney transplant recipients.   methods : the study was conducted in a population of 239 subj...

background: human cornea expresses functional fas-ligand capable of killing fas+ activated lymphocytes. fas expression is partly regulated by -670 a/g polymorphism in the promoter region of fas gene. objective: the aim of the present study is to determine the association between fas-670a/g polymorphism and survival of corneal transplantation. methods: in 276 graft recipients who mainly underwen...

The main objectives of this study were to remove surface-active agents and to predict the adsorption rejection models.  The effects of surfactant concentration and PAC amount on the adsorption were determined. For both surfactants, It was found that the adsorption values also increased when PAC amount increased. It was observed that the rejection values are different for the adsorption of C...

for monitoring of renal transplant function, serum b2m was evaluated in 23 recipients. according to clinical diagnosis the patients were in four groups: 1) successful renal transplant the mean concentration of sb2m pretransplantation was 73.1±26.1 mg/l but decreased to nearly normal level (4.43±1.17 mg/l) within 24-48h and then reached to 3.1 mg/l duting 20 days after transplantation. 2) renal ...

introduction: acute rejection of renal transplant is a serious and common systemic inflammatory disorder which leads to decreasing half-life of transplant organ. current diagnoses method is an invasive biopsy procedure on allogtraft kidney. therefore, applying a novel and noninvasive diagnostic method such as granzym b level in acute renal transplantation could help patients and improves surviv...
