Research background: Globally, many countries are dependent on natural resources, for this reason, their revenue management becomes an important aspect economies. It is necessary to understand the relations between institutional factors and resource from global point of view. means identify which aspects impact both positively negatively management.

In an ideal plasmonic surface sensor, the bioactive area, where analytes are recognized by specific biomolecules, is surrounded by an area that is generally composed of a different material. The latter, often the surface of the supporting chip, is generally hard to be selectively functionalized, with respect to the active area. As a result, cross talks between the active area and the surroundin...

Abstract. Eliminating the leakage current is one of the most important issues for transformerless inverters in grid-connected photovoltaic system applications, where the technical challenge is how to keep the system common-mode voltage constant to reduce the leakage current. A novel singlephase three-level topology for transformerless photovoltaic systems is presented in this paper. Compared wi...
