Microbial contamination of fuel has been the cause of several problems in transportation and storage of these products. Due to the lack of previous studies related to these problems in Costa Rica, bacterial quality was evaluated biannually in automotive fuels stored in the four oil distribution facilities of the Costa Rican Petroleum Refinery (RECOPE). In 12 oil storage tanks, for a total of 96...

The Hanford Site in southeastern Washington State is the location of the largest nuclear waste storage area in the United States. Since plutonium production facilities at Hanford were shut down in 1987,cleaning up the leftover waste at the Hanford Site has become one of the largest environmental cleanup projects in history. Legal, political, technical, and social aspects of the cleanup contribu...

The study assessed the quality of water obtainable in six (6) storage tanks present male and female hostels on Federal University Dutse campus. Physicochemical analyses; temperature, pH, turbidity, electrical conductivity, nitrate, phosphate were conducted using standard methods. Presumptive, confirmed, completed tests employed to determine total fecal coliforms from samples most probable numbe...

In Thailand, water-storage jars, barrels, drums, pails, and tanks constitute vast developmental sites for Aedes aegypti in urban, semiurban, and rural areas. Earthen water jars, cement jars, and concrete tanks constitute the greatest proportion of artificial containers where Ae. aegypti breed. This species is a major vector of the causal agents of dengue and dengue hemorrhagic fever, and vector...

We characterized the physical/chemical conditions and the algal and bacterial assemblages in ballast water from 62 ballast tanks aboard 28 ships operated by the U.S. Military Sealift Command and the Maritime Administration, sampled at 9 ports on the U.S. West Coast and 4 ports on the U.S. East Coast. The ballast tank waters had been held for 2–176 days, and 90% of the tanks had undergone ballas...

PURPOSE The incidence of acanthamoeba keratitis (AK) in the UK is some 15 times that in the United States and seven times that in Holland. To investigate reasons for this higher frequency, a study of the role of domestic tap water as a potential source of AK was undertaken. METHODS Tap outlets from the homes of 27 patients with culture-proven AK were sampled and cultured for free-living amoeb...

the main objective of this article is evaluation of the simplified models which have been developed for analysis and design of liquid storage tanks. the empirical formulas of these models for predicting maximum sloshing wave height (mswh) are obtained from mass spring models (msm). a finite element modeling (fem) tool is used for investigating the behavior the some selected liquid storage tanks...

Water transport networks (WTN) are generally used to convey water from production plants or sources to storage tanks close to the consumptions areas. Tanks are usually built with enough elevation to guarantee the service pressure required for their associated consumption area. WTNs contain large water mains and control elements, such as pumping stations and valves, linking the sources to consum...
