Thermal decomposition of two coal samples obtained from Top Seam Sibi (TSS) and Sore Range Quetta (SRQ) coal fields in their raw and acid washed forms were carried out in an open type tubular pyrolyzer coupled to a gas chromatograph with FID. Elemental analyses were carried out with Scanning Electron Microscope-Energy Dispersive X-rays (SEM-EDX) analyzer. Effect of inherent mineral contents...

The mechanisms of resistance of Pseudomonas aeruginosa to benzalkonium chloride (BC) were studied. The effluence of cell components was observed in susceptible P. aeruginosa by electron microscopy, but resistant P. aeruginosa seemed to be undamaged. No marked changes in cell surface potential between Escherichia coli NIHJC-2 and a spheroplast strain were found. The contents of phospholipids (PL...

background and objectives:hormozgan province is located in the south of iran, bordering waters of the persian gulf and oman sea. due to the antioxidant potential of plants which might be responsible for their medicinal properties, the antioxidant properties of four medicinal plants of the region were evaluated. methods: the antioxidant properties of chrozophora obliqua, daphne mucronata, salvia...

The processing and analysis of the Mizar library has been performed using the infrastructure of the University of Bialystok High Performance Computing Center. In the current Mizar language, direct linking to statements formulated as compound conditions is prohibited. This particular language feature has often been considered by the users as an unnecessary disruption of the natural course of pro...

Following several recent approaches, working memory is argued to consist of a subset of representations that are within the scope of active processing and a larger set of recently activated, but non-attended representations. A response-signal speed-accuracy tradeoff (SAT) and complementary reaction time variant of a probe recognition task were used to measure the retrieval of categorized materi...

At 24 hours after administration of a single dose of 3-4 mg. of l-hydroxy-2-acetylaminofluorene-1-C14 (1-hydroxy-AAF-l-C14) intraperitoneally to rats, 75 per cent of the dose had been excreted in the urine and feces. About 5 per cent of the injected radioactivity was present in the gastrointestinal contents, and only 1-2 per cent re mained in the tissues of the rat. Radioactivity equivalent to ...
