Recombination events between human enteroviruses (HEV) are known to occur frequently and to participate in the evolution of these viruses. In a previous study, we reported the isolation of a panel of viruses belonging to the Human enterovirus species C (HEV-C) that had been cocirculating in a small geographic area of Madagascar in 2002. This panel included type 2 vaccine-derived polioviruses (P...
A 53-year-old man with a history of a bilateral lung transplantation (LT) at the age of 39 underwent electrophysiological testing of supraventricular tachycardia (SVT). At baseline, the SVT persisted, and exhibited positive P waves in the inferior leads and lead V1. The activation map in the left atrium (LA) revealed a centrifugal pattern from the right pulmonary vein (RPV) cuff ( F1 Panel A). ...
Photovoltaics (PV) are the most abundant, perennial, environment friendly and distributed source of energy all over the globe. In this paper, the method to increase PV extraction efficiency for 60W panel with improved DMPP (Distributed Maximum Power Point) even on changing temperature and irradiance have been mapped and discussed. In order to achieve this, the components and subsystems have bee...
The Janus kinase 2 mutation, JAK2617V>F, is myeloid neoplasm-specific; its presence excludes secondary polycythemia, thrombocytosis, or bone marrow fibrosis from other causes. Furthermore, JAK2617V>F or a JAK2 exon 12 mutation is present in virtually all patients with polycythemia vera (PV), whereas JAK2617V>F also occurs in approximately half of patients with essential thrombocythemia (ET) or ...
The most important energy source of the world is sun. Solar can be converted to electricity by using photovoltaic (PV) solar panels. It known that maximum electrical efficiency PV panels around 15%-20%. Therefore, it clear are not very efficient. This due some reasons. One these reasons increase in temperature panel. should cooled means any cooling methods. For this reason, study, effect on has...
In the recent years, the solar energy has become one of the most important alternative sources of electric energy, so it is important to operate Photovoltaic (PV) panel at the optimal point to obtain the possible maximum efficiency. This paper presents a new optimization approach in order to maximize the output electrical power of the PV module. The proposed optimization technique is based on a...
