We propose a method based on Open MPI and BLCR checkpoints to allow executing MPI applications over non-dedicated and failure-prone computing infrastructures. To this end, the method allows automatic detection and recovery of MPI applications in case of failures while generating minimum overhead to the overall execution process. The method was tested by(More)
This study assessed the treatment of domestic wastewater to find the optimum vertical flow-constructed wetland (VFCW) configuration under tropical conditions. Eight pilot-scale configurations units were studied to compare between fine sand and medium gravel used as substrate, two feeding frequencies (20 pulses d-1 and 10 pulses d-1), and the presence or(More)
The Helicobacter pylori CagA protein was the first bacterial oncoprotein to be identified as important in the development of human malignancies such as gastric cancer. It is not clear how it is able to deregulate a set of cell control mechanisms to induce carcinogenesis following translocation into human gastric epithelial cells. It is likely, however, that(More)
Pyruvate carboxylation was stimulated by 2 gastric secretagogues, histamine and dibutyryl cyclic AMP, and by butyrate. Thiocyanate, an inhibitor of acid secretion, produced a slight decrease. Avidin significantly reduced acid secretion and this effect was overcome by biotin and oxalacetate. The results suggest that carboxylation of pyruvate is one of the(More)
