the ali-abad porphyry copper deposit is located in the central iranian magmatic belt. as a result of subduction magmatism, oligo-miocene leucogranitoid rocks have intruded into conglomerates of lower cretaceous age. due to contact metamorphism the following mineral assemblage has occurred in the altered conglomerate: garnet (andradite-grossular) + epidote+ quartz + calcite + pyrite skarnificati...

In this study, a computational model which simulates the growth of crystalline deposits from dripping salt solution is developed and validated. This problem is of interest to the nuclear industry where the morphology of deposited material impacts on its associated criticality risk. An existing model for simulating geological-stalagmite formations is adapted to the case of dripping salt-solution...

Deep drawing is an important process used for producing cups from sheet metal in large quantities. The process parameters and viscosity of fluid is maintained the major role in the hydro forming-deep drawing process. Hydraulic pressure can enhance the capabilities of the basic deep drawing process for making metal cups. Hydraulic pressure contributes positively in several ways to the deep drawi...

Wet Compression Moulding (WCM) provides large-scale production potential for continuously fibre-reinforced structural components due to simultaneous infiltration and draping during moulding. Due thickness-dominated of the laminate, comparatively low cavity pressures are sufficient - a considerable economical advantage. Similar other Liquid (LCM) processes, forming strongly interact process. How...

The pericardium is one of the serosal cavities of the mammals. It consists of two anatomical structures closely connected, an external sac of fibrous connective tissue, that is called fibrous pericardium and an internal that is called serous pericardium coating the internal surface of the fibrous pericardium (parietal layer) and the heart (visceral layer) forming the pericardial space. Between ...

The penetration of daptomycin, a new lipopeptide antibiotic, into inflamed meninges ranged between 4.37 and 7.53% (mean, 5.97%). Daptomycin was very efficacious in the treatment of experimental pneumococcal meningitis, producing a decrease of -1.20 +/- 0.32 Deltalog(10) CFU/ml. h in the bacterial titer of Streptococcus pneumoniae against a penicillin-resistant strain and of -0.97 +/- 0.32 Delta...

The effectiveness of gatifloxacin therapy (15 mg/kg every 5 h [q5h]) was compared with that of meropenem (75 mg/kg q5h) and cefotaxime (75 mg/kg q5h) therapy in experimental meningitis caused by a beta-lactamase-producing strain of Escherichia coli. Gatifloxacin therapy was more rapidly bactericidal than cefotaxime but similar to meropenem therapy (bacterial killing rates at 5 h, 0.83 +/- 0.26,...

Detection of group B streptococcus (GBS) antigen in urine by latex particle agglutination (LPA) may facilitate the rapid diagnosis of GBS sepsis. We sought to compare three commercial LPA assays with specimens that were spiked with type-specific antigen, group-specific antigen, or type III organisms. There were sensitivity differences between the assays, but the Bactigen assay performed best, d...

This study examined the penetration of aztreonam into the cerebrospinal fluid (CSF) and brain in noninfected rabbits and rabbits with experimental meningitis caused by Pseudomonas aeruginosa. Animals received either 600 or 1,200 mg of aztreonam administered intravenously over 6 h. Aztreonam did not readily enter the CSF in the absence of meningitis. In noninfected animals, mean concentrations i...
