Kaolin deposits, situated ~10 km north-west of Gonabad (eastern Iran), formed by the intrusion of hydrothermal fluids from a granite dyke in the western part of the study area, and the alteration of rhyolite, dacite and rhyodacite related to Eocene volcanism. There are four major kaolin quarries. The rocks in the investigated area are mainly slate, dacite, rhyolite, andesite-trachyandesite, and lithic...
ObjectiveUmbilical cord blood (UCB) has been a reasonable alternative to granulocyte colony‐stimulating factor‐mobilized peripheral blood or bone marrow, as a source of hematopoietic stem cells with a lower risk of graft‐versus‐host disease. In immunocompromised hosts after transplantation, the risk of viral infection in adults, especially with beta‐herpesviruses such as human herpesvirus‐7 (HHV‐7),...
The dual ex-vivo perfusion of human placental tissue is useful to study inflammatory pathways. We found significant TNF-α release in negative controls similar in concentration to lipopolysaccharide (LPS) stimulated placentas. The aim of the current study was to (i) identify sources driving TNF-α release and (ii) develop an approach to control for it.(i) To determine sources leading to TNF-α release,...
A programming disturb mechanism in the uniform channel program and erase (UCPE) flash FPGA cell is investigated. High junction leakage from the inhibit bits on the selected row and unselected columns introduce additional gate disturb failures in a high density Flash FPGA product. It is observed that the total substrate current from the inhibit bits can induce the turn-on of a parasitic bipolar transistor...
