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 ...
Biological stability of drinking water refers to the concept of providing consumers with drinking water of same microbial quality at the tap as produced at the water treatment facility. However, uncontrolled growth of bacteria can occur during distribution in water mains and premise plumbing, and can lead to hygienic (e.g., development of opportunistic pathogens), aesthetic (e.g., deterioration...
Irrigated agriculture is dependent on an adequate water supply of usable quality. Water used for irrigation can vary greatly in quality depending upon type and quality of dissolved salts. Salts are present in irrigation water in relatively small but significant amounts. The problems that result very both and kind, degree and modified by soil, climate and crop. The aim this paper is to monitor t...
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 ...
Adequacy of water supply plays a vital role in maintaining lawn health. Water need to be dispersed intelligently to provide a sufficient amount of moisture to the soil. Conventional system was investigated and it is found that the system used excessive amount of water and the amount dispersed may not be suitable for the moisture level of the lawn since it does not consider soil moisture based o...
Measured inputs in control domains are often continuous. A discretization function is needed to map continuous inputs into multiple intervals or ranges of input values, so that they can be used as symbolic inputs to a rule-based system. The discretiza-tion parameters used to determine each interval play a critical role in the overall eeectiveness of a rule-based system. We propose a Hybrid Inte...
careful observer to detect this phenomenon. It remains for future research to characterize the relationships of flash brightness and shape with charge, momentum, and trajectory. THoMAs F.

An investigation of a childhood leukemia cluster by US Centers for Disease Control and Prevention revealed that residents of the Carson Desert, Nevada, are exposed to high levels of W and this prompted an investigation of W in aquifers used as drinking water sources. Tungsten concentrations in 100 ground water samples from all aquifers used as drinking water sources in the area ranged from 0.27...
