Salt caverns are an attractive solution to the growing energy demand in view of their large storage capacity, safety operation and long time. The designing process salt is still considered a complex issue despite progress geotechnical, construction exploration methods. Finding optimal shape dimensions cavern given geological conditions difficult engineering problem stability requirements. In th...

We study two reservation deposit policies for a service rm to increase its revenue through higher capacity utilization. First, under the no deposit policy, the rm requires no reservation deposit and imposes no no show penalty. Anticipating potential no shows, a rm may overbook; hence, there is no guarantee that the reserved service will be provided under the no deposit policy. On the contrary, ...

The results of osmotic membrane distillation carried out for 2.5 years were presented in this work. The influence of the process conditions, such as temperature and brine concentration on the permeate flux, was investigated. The saturated NaCl solutions and distilled water were used as a stripping solution and feed, respectively. A continuous regeneration of stripping solution was conducted usi...

The coenzyme content was followed throughout the purification by the assay method described in a preceding paper (2). Hog liver was found most suitable. Ten 50 pound batches of liver were used in this preparation. Since rapid autolysis of Co A occurred, the yield was largely dependent on the rapidity with which the livers were obtained. Livers from still warm hog bodies were cut into small port...

We describe an adaptation and modification of the enzyme-labeled immunosorbent assay (ELISA), which yields information on the quantity and distribution of surface antigens on erythrocytes. The distribution assay, named "ELADA" (for Enzyme-Linked Antigen Distribution Assay), involves use of an alkaline phosphatase-immunoglobulin conjugate with alpha-naphthol phosphate and a diazonium salt as sub...

The effects of shungite rocks (ShR) from Turastamozero (1, 5, 25, 100%), Nigozero 10, 100%) and Zazhogino deposits added to growing substrate on wheat ( Triticum aestivum L.) barley Hordeum vulgare plant growth development were studied. Silica sand was used as a control for growing.Plants grown in chambers at temperature 23°C or 15°C, PAR 200 µmol m -2 s -1 irrigated with complete 25% nutrient ...

The cleaning effect of heavy rain (the rainfall reaches 5 mm every day) on surface contamination of insulators is more effective than dew, fog, mist, and other light rain conditions which can initiate leakage currents and increase the likelihood of flashover. It is well understood that heavy rain can wash away contamination from the surface of high voltage (HV) insulators and thereby reduce the...

The goal of this paper is to improve our understanding of the costs and benefits of explicit deposit insurance. To this end, we compare the opportunity-cost value of deposit insurance services for a large sample of banks drawn from countries with or without explicit deposit insurance. After correcting for certain bankand country-specific factors, we find that the existence of explicit deposit i...
