background central dialysate fluid delivery systems (cdds) are used by dialysis centers in japan, and although these systems are effective at delivering dialysate, they have a complex piping network with numerous sites where contamination can develop. in japan, cleaning disinfectants have been clinically evaluated based on endotoxin levels and bacterial counts, but there have been no published ...

An experimental apparatus has been developed to measure the CO 2 solubility in water, brines, polymer solutions, white oil and drilling fluids using sample analysis method. The results show that electrolytes can significantly reduce of water salting-out effect be enhanced by increasing molar concentration salt ions. influences different polymers are similar, which gas a certain extent. Furtherm...

in some instances, it is inevitable that large amounts of potentially hazardous chemicals like chlorine gas are stored and used in facilities in densely populated areas. in such cases, all safety issues must be carefully considered. to reach this goal, it is important to have accurate information concerning chlorine gas behaviors and how it is dispersed in dense urban areas. furthermore, mainta...

correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

INTRODUCTION Solubility of root filling materials is heavily influenced by the environment they are in contact with. This study compared the solubility of ProRoot MTA in deionized water and synthetic tissue fluid. MATERIALS AND METHODS Forty specimens of prepared MTA were immersed in deionized water and synthetic tissue fluid (20 samples each). The solubility was assessed after 7 and 28 days....

In their recent study, Pering et al. (2017) presented a novel method for measuring volcanic water vapor fluxes. Their method is based on imaging volcanic gas and aerosol plumes using a camera sensitive to the near-infrared (NIR) absorption of water vapor. The imaging data are empirically calibrated by comparison with in situ water measurements made within the plumes. Though the presented method...

in this research the mechanical behavior of an expansive soil (with different pore fluid) was investigated under the constant and variable temperature through experimental tests. the soil samples with different pore fluid (distilled water, nacl and cacl2 with concentration of 250 gr/lit) were prepared by static compaction method. experimental testes were conducted in two modified odometer under...

There is continuing concern over potential impacts of widespread application of nutrients and pesticides on ground- and surface-water quality. Transport and fate of nitrate and pesticides were investigated in a shallow aquifer and adjacent stream, Cow Castle Creek, in Orangeburg County, South Carolina. Pesticide and pesticide degradate concentrations were detected in ground water with greatest ...
