Understanding of current distributions in proton exchange membrane fuel cells (PEMFCs) is crucial for designing cell components such as the flow field plates and the membrane electrode assembly (MEA). In this study, the spatial current density distributions in a single PEMFC with three...

This paper examines the major driving forces behind the conversion of arable land to non-agricultural uses in china during the reform years (1978-1995). Both graphic techniques, based on a Geographic Information System (GIS), and an econometric modeling approach are employed. It is found that...

Malaria is an infectious disease that is caused by a group of parasites of the genus "Plasmodium". Characterizing the association between polymorphisms in the parasite genome and measured traits in an infected human host may provide insight into disease aetiology and ultimately inform new...

A nonmonotonic variation of the isothermal in-plane and out-of-plane MR with the field is observed. The out-of-plane MR is...</subscript></subscript></superscript></subscript><//subs></subscript></subscript></subscript>
