Improved handoff stability using an enhanced vertical handoff decision algorithm

  The next generation wireless networks generally called 4G networks will most likely be actualized by the integration of present day available heterogeneous wireless networks. Integration of these networks will largely depend on the process of Vertical Handoff (VHO). VHO occurs when an active communication session is transferred between different heterogeneous radio access technologies. Several...

Chemical constituents and biological activities of saponin from the seed of Camellia oleifera

    Camellia oleifera Abel (Theaceae) is a woody plant that is native to China. It is an important source of edible oil and is used in traditional medicine. It contains a triterpenoid saponin with high medical value that can be obtained from the seed cake residue (marc) after oil extraction. This saponin has prospects for wide applications. In this review, we summarize...

Degradation of polycyclic aromatic hydrocarbons: Role of plasmids

    Polycyclic aromatic compounds are a group of highly recalcitrant organic pollutants. The initial steps in the degradation of polycyclic aromatic hydrocarbon (PAHs) involve the dihydroxylation of the aromatic ring, a step catalysed by dioxygenase enzymes. The degradation of many xenobiotic and hydrocarbon compounds is known to be mediated by plasmid encoded enzymes. In this...
