The Clitoria ternatea, Solanum nigrum and Aloe vera leaves were extracted serially by the solvents of increasing polarity (petroleum ether, chloroform and ethanol) were tested for their free radical scavenging activity against DPPH. The petroleum ether extracts of Clitoria ternatea, Solanum nigrum and Aloe vera leaves were the most effective scavenging of DPPH. These plant extracts were also an...

Using a sample from January 1988 to December 2005 for exports of five Japanese major ports to six destination countries, we examine the effect of market share (with respect to competitors from the same country) on exchange rate pass-through (henceforth, ERPT). Our dataset is unique, allowing us to control for market shares among competing exporters with the same nationality. A close examination...

Our understanding of the processes underlying the formation of heavy oil has been transformed in the last decade. The process was once thought to be driven by oxygen delivered to deep petroleum reservoirs by meteoric water. This paradigm has been replaced by a view that the process is anaerobic and frequently associated with methanogenic hydrocarbon degradation. The thermal history of a reservo...
