Solar energy plays an important role in the global energy framework for future. Comparing with conventional generation systems using fossil fuels, the cost structure of photovoltaic (PV) systems is different: the capital cost is higher while the operation cost is negligible. Reliabilities of the PV system can also influence the cost for producing electricity. Investors, planners and regulators ...

In this issue of the Journal. Ernst et al.1 report three cases of total pulmonary vein (PV) occlusion in 239 patients who underwent an ablation procedure for atrial fibrillation (AF). Patients initially were evaluated by internists and pulmonologists and underwent extensive evaluation before the diagnosis was finally made. Despite treatment with thrombolytics, glycoprotein IIb/IIIa inhibitors a...

This project proposes a voltage stability for an interline photovoltaic (I-PV) system. In an I-PV system, the inverters in a PV plant are reconfigured in such a way that two or more distribution networks / feeder are interconnected. The I-PV system is operated as a flexible ac transmission system (FACTS) device STATCOM to regulate the point of common coupling voltage on either feeder. One of th...

Lysobacter antibioticus 13-6, isolated from the roots of Chinese cabbage, effectively controls the pathogens Plasmodiophora brassicae, Xanthomonas oryzae pv. oryzicola, X. oryzae pv. oryzae, Xanthomonas axonopodis pv. dieffenbachiae, and Pseudomonas syringae pv. tabaci. We report the first draft genome sequence of the L. antibioticus species in China.

Poliovirus (PV) is the causal agent of paralytic poliomyelitis, a disease that involves the destruction of motor neurons associated with PV replication. In PV-infected mice, motor neurons die through an apoptotic process. However, mechanisms by which PV induces cell death in neuronal cells remain unclear. Here, we demonstrate that PV infection of neuronal IMR5 cells induces cytochrome c release...

Poliovirus (PV) is easily transferred to humans orally; however, no rodent model for oral infections has been developed because of the alimentary tract's low sensitivity to the virus. Here we showed that PV is inactivated by the low pH of the gastric contents in mice. The addition of 3% NaHCO3 to the viral inoculum increased the titer of virus reaching the small intestine through the stomach af...

PURPOSE To investigate the efficacy of total prostate-specific antigen (tPSA) and free prostate-specific antigen (fPSA) for the estimation of prostate volume (PV) in pathologically-proven benign prostatic hyperplasia (BPH) patients. METHODS From January 2010 to March 2013, 165 Korean men with a PSA less than 10 ng/mL who were diagnosed without prostate cancer by prostate biopsy were enrolled....

Hybrid power system can be used to reduce energy storage requirements. The influence of the Deficiency of Power Supply Probability (DPSP), Relative Excess Power Generated (REPG), Energy to Load Ratio (ELR), fraction of PV and wind energy, and coverage of PV and wind energy against the system size and performance were analyzed. The technical feasibility of PV-wind hybrid system in given range of...

LETAS, Department of Physics, Faculty of Science, University Mohamed the First, Oujda 60000, Morocco. ___________________________________________________________________________________ Abstract: In this paper, we analyze the design and the realization of a photovoltaic system (PV system) provided with a digital MPPT regulator and a dysfunction detection circuit of the PV system (DDCS). The rol...

Installing sustainable and renewable energy systems is a promising way of relieving Hong Kong’s dependence on imported fossil fuels. Solar photovoltaic (PV) technology is a perfect solution for Hong Kong as it fits the economic and geographic situation. Through a review of the PV development history of five leading PV countries, Germany, Japan, Italy, Mainland China, and the USA, this paper ser...
