Scale formation and well plugging due to the incompatibility of injected waters is a critical field problem in oil recovery. A water injection process was successfully performed when the identification of the source of water, water quality considerations, and laboratory compatibility tests were considered. When different waters are mixed, it is necessary to evaluate their compatibility prior to...

Mineral scale deposition in near wellbore regions of injection wells is one of the main challengeable issues during the water injection process, which magnifies the importance of robust models in predicting the amount of mineral scale deposition such as calcium sulfate. One of the main challenges of CaSO4 scale is in carbonated reservoirs, in which sensitive behavior is observed in related to t...

background: today with population growing, surface water is one of the most important water resources used for domestic and industrial consumptions. in order to purify the surface water, coagulants materials are used. the purpose of this study was to assess the possibility of using poly aluminum chloride (pacl) in water refinery number 1 in city of orumieh and investigating its health effects. ...

We determined the effect of performing antimicrobial susceptibility tests in five different anaerobic incubation systems: GasPak jar, large GasPak jar, evacuated-gassed anaerobic jar, anaerobic chamber, and Bio-Bag. Growth of the anaerobes was equivalent in all five incubation systems. The results of testing 38 anaerobes against 11 antimicrobial agents were comparable for the anaerobic jars and...

If depicted objects visually remain where they are, but are linguistically described as moving to new locations (‘onto the table’), subsequent reference to them directs attention to their new locations. But, do these attentional shifts depend on updated spatial screen coordinates, or new object associations? We investigated situations wherein depicted containers moved between spatial locations ...

An anaerobic glove box designed for moderate-sized hospitals or research laboratories is described. The compact vinyl and metal enclosure becomes anaerobic rapidly after inflation, requires no vacuum pump, and provides incubator space equivalent to 15 standard anaerobic jars.

Mate choice copying has been documented extensively in the laboratory with almost no supporting data available from studies in the wild. We investigated male and female mate choice copying in a wild population of the sailfin molly, a species that shows copying in the laboratory. We set up two upside-down plastic tanks in a river, with two jars of water on each tank. In male mate choice trials w...

In Thailand, ceramic jars (135-200 liters) covered by aluminum lids commonly are used to store water for household use. In laboratory cages, gravid female Aedes aegypti (L.) were able to enter and oviposit in a covered water jar. Although the aluminum lid was not a complete barrier to gravid females, it reduced the number of eggs oviposited by 77%. A vertically oriented foam rubber ring which w...

in a preliminary study carried out in a simple field laboratory in bandar-abbas, southern iran, five isolates of p. falciparum collected from the patients was cultured in rpmi 1640 medium with human serum in the tightly closed screw capped vials without any devised system for adjustment of co2 and o2 mixture. the same isolates were also cultured, simultaneously, in petri-dishes using jensen-tra...
