INTRODUCTION The results of a 2001-2005 polycythemia vera (PV) investigation in Eastern Pennsylvania revealed a disease cluster plus underreporting and false reporting to the Pennsylvania Cancer Registry (PCR). PURPOSE The objectives of this study were 1) to assess PV reporting to the PCR in 2006-2009, 2) to determine whether a cancer cluster persisted, and 3) to determine whether other myelo...

Energy is essential component for improving the living condition of the civilization. One of the major concerns in the power sector is that day to day increasing power demand has forced to use the fossil fuels in extreme causing the increasing serious environmental problems thus it is essential to use renewable energies which are characterized by their negligible pollution level and environment...

PURPOSE Plasmalemmal vesicle associated protein-1 (PV-1) is up-regulated in the endothelium of human glioblastoma. We sought to further characterize the expression pattern of PV-1 in human brain tumors and interrogate its role in brain tumor angiogenesis. EXPERIMENTAL DESIGN Quantitative reverse transcription-PCR and in situ hybridization were used to measure PV-1 expression in a panel of 46 ...

Maximization of power from a solar photovoltaic (PV) module is of special interest as the efficiency of the solar PV system is very low. A maximum power point tracker (MPPT) is needed to operate the PV array at its maximum power point. The present work describes the design and implementation of a MPPT for the solar PV array connected to a resistive load. The design consists of a dc-dc boost con...

Photovoltaic (PV) technology is one of two modes of energy generation which utilize solar energy as its source. The rooftops of buildings can be utilized for solar power generation using this technology, and are considered to be highly promising sites for urban PV installations due to land space limitations. However, to properly plan such installations decision makers would need to have detaile...

Abstract: NMOS-based Integrated Modular Bypass for Use in Solar systems (NIMBUS) is designed as a replacement for the traditional bypass diode, used in common solar panels. Because of the series connection between the individual solar cells, the power output of a photovoltaic (PV) panel will drop disproportionally under partial shading. Currently, this is solved by dividing the PV panel into su...

Power from solar panel is affected by insolation and temperature variation which can be minimized by MPPT system. In this paper to extract maximum power from solar system, perturb and observe technique of MPPT is used. A PV system require proper battery charge controller to balance the power flow from PV system to battery and load such that photovoltaic power is utilized effectively. In this bu...

Electricity generation purposes renewable energy brings a important role especially Photovoltaic (PV) panels that can be covered our basic energy (electricity) needs. This photovoltaic panels cover a domestic level (solar power for home), commercially (solar power for commercial applications) or at the community level. Here used this photovoltaic panel as an input of PV-transformer-less inverte...
