• The determination of total body water by measurements of the distribution A'olume of antipyrine was originally proposed by Soberman, Brodie, et al. The applicability of the method has been extended by the use of the more easily determined aeetylaminoantipyrine. It has also been suggested' that the iodinated derivative of antipyrine labeled with I might be a satisfactory substitute for the par...

A sequential injection system with dual analytical line was developed and applied in the comparison of two different detection systems viz; a conventional spectrophotometer with a commercial flow cell, and a multi-reflective flow cell coupled with a photometric detector under the same experimental conditions. The study was based on the spectrophotometric determination of phosphate using the mol...

Dense oceanic overflows mix with surrounding waters along the descent down the continental slope. The existing parameterizations for entrainment in dense currents account primarily for the shear-induced entrainment at the interface between the dense flow and the ambient fluid. However, the turbulence generated by roughness elements at the bottom boundary, which produces an enhanced drag, can be...

Nucleation rate measurements of water in the presence of nitrogen as a carrier gas are reported at total pressures near 10, 25, and 40 bar, and temperatures of 230 and 250 K. The results were obtained using our pulse-expansion wave tube, particularly suited for high pressure nucleation research. Enhanced fugacity of water vapor in the mixture, due to the presence of nitrogen, was quantitatively...

In 1921, Brunn showed that injection of neurohypophysial extracts causes a temporary increase in the body water content of Amphibia kept in water. Since then the existence of this water-balance effect has been confirmed by numerous workers, but its mechanism is by no means fully understood. The increase in body water following pituitrin injection might be due either to an increased rate of wate...

Water flooding plays an important role in recovering oil from depleted petroleum reservoirs. Exactly how the microbial communities of production wells are affected by microorganisms introduced with injected water has previously not been adequately studied. Using denaturing gradient gel electrophoresis (DGGE) approach and 16S rRNA gene clone library analysis, the comparison of microbial communit...

abstract this study was carried out to investigate the hepatoprotective effect of deuterium depleted water with satureja rechingeri essential oil on liver damage. for this purpose, the adult male rats were divided into 16 groups. the negative control group used tap water in 14 days following dmso i.p injection at day 15th. the treatment group with acetaminophen received tap water in 14 days fol...

OBJECTIVE Two experiments were conducted to evaluate vitamin D3 administration to nursery pigs by injection or in drinking water on serum 25-hydroxycholecalciferol (25-OHD3) concentrations. METHODS At weaning, 51 pigs (27 and 24 pigs in experiments 1 and 2, respectively) were allotted to vitamin D3 treatments. Treatments in experiment 1 were: i) control (CON), no vitamin administration beyond...

a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such...
