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 ...
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 ...
Do the helminth parasites of wood mice interact?
(
Blackwell Science Ltd
, 2005 , Article)
Two published data sets of helminths of the wood mouse Apodemus sylvaticus (L.) were analysed to test the hypothesis that the structure of these component communities is influenced by interactions between species. A range ...
