Concentrating solar power plants with direct steam generation have the possibility to store generated energy in thermal form very easily. This is achieved by using two-phase accumulators which heat stored directly tanks filled water and a saturated state. The Llo plant, owned SUNCNIM France, has nine such connected parallel. During unloading of storage, withdrawn from operators observe oscillat...

Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...

The proper management of oily sludge from petroleum products storage tanks is necessary because inappropriate methods for dredging of tanks may result in high costs and increased environmental pollution. The purpose of the current study is to rank the strategies outlined by strengths, weaknesses, opportunities and threats analysis using data envelopment analysis model, which provides enriched i...

Recently, in most of the condensate tank production projects, two main activities of welding and painting are done in manual and automatic ways. The purpose of this study is "green supply chain management" of these activities in order to select the best production method. For this purpose, by literature reviews and using Delphi and DEMATEL techniques, the indicators and sub-indicators of green ...

Despite the reported health-related advantages of the use of warm water in bidets, there are health-related disadvantages associated with the use of these toilet seats, and the bacterial research is sparse. We conducted a survey on the hygienic conditions of 127 warm-water bidet toilet seats in restrooms on a university campus. The spray water from the toilet seats had less residual chlorine th...

Due to the importance of water variables conditions and available food in the development and survival of fish larvae, the current research evaluates the effects of two different food treatments (ration + zooplankton and only zooplankton) and water quality in tanks with Brycon orbignyanus larvae. Total water transparency (45 cm) has been mainly associated with short residence time, continuous w...

This paper is based on a series of measurements taken on WWII historic shipwrecks that resulted from the effects of Operation Hailstone in February 1944 on the Japanese merchant fleet which was assembled in Chuuk lagoon, Federated States of Micronesia. More than 65 shipwrecks and 250 aircraft were sunk during two main bombing raids. The vessels lost covered a wide range of underwater orientatio...

In the course of the investigation into the bacteriology and epidemiology of cholera, which we are at present conducting in the Asansol Mining vSettlement, we found that during the hot dry months of the year (February to June)?which also constitute the epidemic season in that area? vibrios were extremely numerous in the smaller village ground tanks much used by the inhabitants for bathing; the ...
