, 2005 , Article)
يهدف البحث إلى التعرف على وقع صناعة المياه المِعبأة في دولة قطر وتجارتها وكذلك جودتها مقارنة مع مياه الشبكة العامة. وًمن بين الأهداف أيضا درًاسة سلوك مستهلكيها وتبني خطة لتطوير صناعتها. وقد اعتمد الباحثان على مصادر بيانات ...
Bordetella pertussis risA, but not risS, is required for maximal expression of Bvg-repressed genes
(
American Society for Microbiology
, 2005 , Article)
Expression of virulence determinants by Bordetella pertussis, the primary etiological agent of whooping cough, is regulated by the BvgAS two-component regulatory system. The role of a second two-component regulatory system, ...
Concentration of sucrose solutions via vacuum membrane distillation
(
Elsevier B.V.
, 2005 , Article)
The potential use of vacuum membrane distillation (VMD) process for the concentration of sucrose solution was examined. The effect of several parameters, including feed temperature, flow rate, and initial sucrose concentration ...
Photodegradation of methylene blue dye by the UV/H2O2 and UV/acetone oxidation processes
(
Elsevier B.V.
, 2005 , Article)
The photodegradation of methylene blue (MB) dye in aqueous solutions was investigated using a laboratory-scale UV lamp in the presence of hydrogen peroxide (H2O2). Different initial concentrations of dyes (10, 20, 30, 40 ...
Theoretical study of laser light generation and color image formation: FA1:Cs+ and FA2:Li+ centers at the low coordination (100) and (110) surfaces of AgCl and AgBr
