a prospective study during 1990-1995 was conducted to assess the risk of rejection and infection in kidney-transplant recipients, who's original kidney had vesico-ureteral reflux (ver). two groups of recipients with and without ver were followed for one month after transplant 24 and 250 cases respectively. the calculated relative risks for the effect of ver showed a moderate increased risk...

We have developed a miniature (1.2 cm2) beta-ray camera prototype to assist a surgeon in locating the margins of a resected tumor. With this technique, one directly detects betas emitted from exposed radio-labeled tissue. When imaging positron emitting radiopharmaceuticals, annihilation gamma ray interactions in the detector can mimic those of the betas. The extent of the background contaminati...

This study investigated the impact of two caustic and one acidic cleaning formulations (namely MC11, PC98, and MC3, respectively) on the properties and separation efficiency of three different nanofiltration (NF) membranes (namely NF270, NF90 and TFC-SR100). Overall, the impact of chemical cleaning on surface properties and rejection was membrane and cleaning reagent specific. It was driven mos...

Problem statement: This study addressed the user’s perceived quality of service requirements in content distribution and investigated the role of QoS. Aware Dominating set based Semantic Overlay Network (QADSON) in surrogate server selection to achieve the specified quality of service. Approach: At first, we constructed the QoS aware dominating set based semantic overlay network which was a vir...
