background surgical site infections (ssis) are the most common nosocomial infections in surgical patients. depending on the source of a traumatic wound, particular pathogens are expected to be present while their prevalence varies in different conditions. this study focused on determination of microorganisms in traumatic wound infection and the frequency of staphylococcus aureus and other organ...
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...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
b ackground: health care-associated infections are an important cause of morbidity and mortality in hospitals. reports have shown that nurses’ uniforms are sources of health care-associated infection transmission. the present study assessed the rate of bacterial contamination of healthcare worker’s white coats in two tertiary hospitals in mashhad, iran. methods: 300 healthcare workers participa...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
Real-time quantitative polymerase chain reaction (qPCR) and digital PCR (dPCR) methods have revolutionized environmental microbiology, yielding organism-specific data of nucleic acid targets in the environment. Such are essential for characterizing interactions processes microbial communities, assessing contaminants environment (water, air, fomites), developing interventions (water treatment, s...
n May 30th 1955 during the First Symposium on the Develpment of Microbiology in Brazil organized by Rio de Janeiro ranch of Society of Americas Bacteriologists (current Amercan Society for Microbiology) coordinated by Prof. Minton hiago de Mello, held in Rio de Janeiro, was formally suggested he creation of the Brazilian Society for Microbiology (SBM) nd a scientific journal under denomination ...
Slow equilibration of introduced chemicals through tortuous pore space limits uniform substrate distribution in soil biodegradation studies. The necessity of introducing poorly soluble xenobiotics via organic solvents, the volume of which is minimized to limit toxicity, likely also affects xenobiotic distribution. Our objective was to investigate relative effects of carrier solvent choice and v...
