Modern electric distribution systems typically contain several feedback-controlled parallel inverters that together form a complex power system. Consequently, number of issues related to stability arise due interactions among multiple inverter subsystems. Recent studies have presented methods where the and other dynamic characteristics paralleled system can be effectively analyzed using impedan...

The employability of seafarers is directly linked to their competency level. Perhaps, this is the main reason why crew members from certain countries enjoy preference in the employment market. Therefore, the sea career prospects of Malaysian seafarers should be viewed from their competency which strongly related to the kind of training offered by Marine Education Training (MET) institutions. In...

While earlier therapeutic strategies for the treatment of hepatitis C virus (HCV) infection relied exclusively on interferon (IFN) and ribavirin (RBV), four direct-acting antiviral agents (DAAs) have now been approved, aiming for an interferon-free strategy with a short treatment duration and fewer side effects. To facilitate studies on the mechanism of action (MOA) and efficacy of DAAs, we est...

BACKGROUND AND PURPOSE Despite evidence that primary stroke center (PSC) certification is associated with improvements in care and outcome, only a minority of hospitals have achieved this certification. We sought to determine hospital-based factors associated with achievement of PSC certification. METHODS We used the 2011 American Hospital Association survey and the 2010 national census for p...

Blazars are among the most energetic and violent objects in the universe. By observing blazars at very high energies (VHE, E > 100 GeV) we can better understand blazar emission mechanisms, jet structure, black hole accretion and the extragalactic background light (EBL). VERITAS, an array of four 12-meter diameter imaging atmospheric-Cherenkov telescopes, performs VHE studies of blazars through ...

By virtue of geographical and historic factors, Ukraine has been playing an important role in oil natural gas deliveries to European energy markets. Such status is basically attributed the fact that West Central countries, while being rather big consumers hydrocarbons, have shortage their own resources.
 On other hand, major reserves are concentrated Russian Federation, Caspian region Gulf...
