Endovascular procedures have been proposed as minimally invasive alternative treatments, allowing safe and effective aortic aneurysm repair. Despite the potential benefits, endovascular stent grafting may elicit an unexpected systemic inflammatory response, called postimplantation syndrome (PIS). The main features of PIS include fever, elevated C-reactive protein levels, leukocytosis and/or coa...

A general overview of visible light photoinduced polymerization reactions is presented. Reaction mechanisms as well as practical efficiency in industrial applications are discussed. Several points are investigated in detail: photochemical reactivity of photoinitiating system (PIS), short overview of available photoinitiators (PIs) and photosensitizers (PSs), mechanisms involved in selected exam...

The capability of regulating power flow in Nigerian Grid System using UPFC is the main focus in this paper. Consequently, three control methods, namely, voltage control through shunt compensation, real power flow control through quadrature voltage injection and reactive power flow control through in-phase voltage injection for the UPFC were examined in order to improve the transient stability o...

Power quality problem causes a misoperation or failure of end user equipments. Distribution network, sensitive industrial loads and critical commercial operations suffer from outages and service interruptions which can cost financial losses to both utility and consumers. In India the use of electronic loads is increasing very fast and the gap between demand and the supply have made the reliabil...
