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...

The Cryogenic Dark Matter Search experiment uses germanium and silicon detectors cooled to cryogenic temperatures in a direct search for weakly-interacting massive particles in our Galaxy. The novel detectors allow a high degree of background rejection by discriminating between electron and nuclear recoils through the simultaneous measurement of the energy deposited in phonons (heat) and ioniza...

Twenty-six bicycle helmets and their associated visors were characterized for radiant heat transfer using a thermal manikin headform in a climate chamber to assess their ability to protect the wearer from heating by the sun. A single configuration for applied radiant flow of 9.3 W was used to assess the roles of the forward and upper vents and the visor. The helmets shielded 50-75% of the radia...

The paper investigates a predictive control algorithm to regulate the output petroleum temperature of the tubular heat exchanger. In the controller design, a Takagi–Sugeno fuzzy model is applied in combination with the model predictive control algorithm. The process model in form of the Takagi–Sugeno fuzzy model is obtained via subtractive clustering from the plant's data set. The neural networ...

Active thermal control of a reactor for YBa2Cu3O7-x chemical vapor deposition is studied using a nonlinear heat transfer model validated by preliminary component testing. LQR and LQE methods are applied to the linearized model for observer-based control. Convergence rates of the controller and observer are indicated by closed-loop eigenvalues and disturbance rejection is assessed with H2 and H∞...

Cellular events that execute life programs are ordered and reproducible, despite the noise and randomness underlying their biochemical reactions. The identification of the processes that ensure this robust operation is essential not only to uncover the salient design principles in organisms, but also to forward-engineer reliable genetic networks for biotechnological and therapeutic purposes. Th...

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...
