background : airborne particulate matter is one of the most important atmospheric pollutants. tile sources of particulate matter in the atmosphere are divided into two groups; 1) natural sources and 2) anthropogenic sources. the important components of airborne particulate matter and invarying concentrations are the ubiquitous components of the lower atmosphere. heavy metals are mainly emitted ...

Bovine mitochondrial elongation factor Ts (EF-Tsmt) stimulates the activity of Escherichia coli elongation factor Tu (EF-Tu). In contrast, E. coli EF-Ts is unable to stimulate mitochondrial EF-Tu. EF-Tsmt forms a tight complex with E. coli EF-Tu governed by an association constant of 8.6 x 10(10). This value is 100-fold stronger than the binding constant for the formation of the E. coli EF-Tu.T...

The electro-Fenton (EF) process is a powerful electrochemical advanced oxidation process. Its development has progressed over the past three decades as clean and effective technique for wastewater treatment. Even though conventional EF been shown to be efficient degradation/mineralization of toxic and/or persistent organic pollutants; it still suffers from some downsides industrial-scale develo...
