studies have shown that patients who do not produce donor specific and / or panel reactive anti-hla antibodies have a longer graft survival. the purpose of this study was to evaluate the posttransplant humoral immune response towards hla-class i antigens and the measurement of the serum creatinine levels which are used in monitoring posttransplant function of kidney. serum samples from 132 rena...

Vetiver grass was harvested at 4, 6 and 8-week regrowth and were ensiled with cassava peels at ratio 60:40 and 100% without cassava peels. The quality and chemical composition of the silages were assessed. The silages along with fresh unensiled re-growths of vetiver grass were fed to WAD goats in a cafeteria method to determine the coefficient of preference of the diets. Results showed that ens...

Methods for the examination of the physico—chemical properties of synthetic membranes are discussed starting with the determination of membrane pore structure and organization. Subse— quently, the determination of equilibrium (e.g. water content, fixed charge concentration) and transport parameters of synthetic membranes is outlined. Using the phenomenological rela— tionships of the thermodynam...

Inductive-coupling scheme for microstrip bandpass filters with quarter-wavelength steppedimpedance resonators is proposed. This is realized by a short-end stub which behaves as a K-inverter. It is investigated that the coupling coefficient of the resonators can be easily controlled by the length of the short-end stub. The filter has a compact size and good stopband rejection by employing the qu...

Due to the difficulties arising in state estimation in Model Predictive Control (MPC) algorithms, Kalman filtering and dynamic matrix control (DMC) estimation approaches were combined in the current work. Then a weighting average of both estimated states was passed to the algorithm. To determine the weighting coefficient of the mentioned average, a fuzzy supervisor was designed to control the c...

This study proposes a patch antenna with an H-shaped slot direct matching and harmonic tuning (rejection) functions for microwave power transfer. enables integrated active in which the amplifier are directly connected without using circuit fundamental frequency rejection filter to improve efficiency of amplifier. The design also reduces total size antenna, allowing higher-density array antenna....

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...
