during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
BACKGROUND There has been renewed call for the global expansion of highly active antiretroviral therapy (HAART) under the framework of HIV treatment as prevention (TasP). However, population-level sustainability of this strategy has not been characterized. METHODS We used population-level longitudinal data from province-wide registries including plasma viral load, CD4 count, drug resistance, ...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
BACKGROUND Disease management programs are expected (and usually contractually required) to reduce total costs in the diseases they manage. OBJECTIVES To discuss the appropriateness of using utilization indexes in lieu of cost and the importance of reviewing utilization trends to determine whether sufficient opportunity exists for a program to be financially effective; and to conduct an analy...
introduction: insertion or deletion of a guanine in -1607 at promoter region of matrix metalloproteinase-1 enzyme creates two allelic types for this gene in the population: 2g and 1g, respectively. 2g allele contains an extra binding site for ets transcription factors that this may increase the level of gene expression. therefore, aim of this study was investigation of the single guanine insert...
