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 ...
BACKGROUND Silver has a long history of use in medicine as an antimicrobial and anti-inflammatory agent. Silver nanoparticles (NAg) offer the possibility to control the formation oral biofilms through the use of nanoparticles with biocidal, anti-adhesive, and delivery abilities. This study aims to evaluate the antibacterial effect of resin luting cements with and without NAg, and their influenc...
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 ...
IT lhas long been known that acetone is present in the urine of patients who have been anaesthetized. Becker, for instance, states' that acetone follows anaesthesia in at least two-thirds of the cases, irrespective of the nature of the anaesthetic or the daration of the anaesthesia, "and that if it be already present it is increased thereby." This has been confirmed by Abram2 in. a series of ca...
Glycerol-induced hyperhydration (GIH) prior to endurance exercise is a strategy that is increasingly used by athletes. Compared with water-induced hyperhydration (WIH), GIH has been shown to reduce diuresis, thereby increasing total body water (TBW). It has never been demonstrated that WIH proved to be more efficient than GIH for increasing TBW. Therefore, we report the case of a trained triath...
Rate and ionic composition of sweat fluid losses and partitioning of evaporative heat loss into respiratory and cutaneous components were determined in six horses during three 15-km phases of exercise at approximately 40% of maximal O2 uptake. Pattern of change in sweat rate (SR) and composition was similar during each phase. SR increased rapidly for the first 20 min of exercise but remained at...
The interpretation of fluctuations in body weight and changes in the state of hydration requires a knowledge of the total amount of water in the organism. This investigation has been directed towards the perfection of a method for measurement of the total body water in the human subject. The increasing availability and lowered cost of both stable and radioactive isotopes has made possible study...
The pharmacokinetics of ceftazidime after a 1-g bolus dose were studied in six elderly volunteers and 12 young subjects. Serum and urine samples were collected in serial order for 24 h and assayed by high-pressure liquid chromatography. The ceftazidime renal clearance was reduced in elderly subjects, a symptom related to normal aging of the kidneys. The decrease in volume of distribution in the...
