Objective(s): Drug-induced atrial fibrillation (AF) is considered an adverse effect of chemotherapeutic drugs. AF is a crucial risk factor for stroke, heart failure, myocardial infarction, and mortality. Pulmonary veins (PVs) are considered triggers inducing AF, and the sinoatrial node (SAN) may modulate PV activity and participate in AF genesis. AF was associated with...

Background Pharmacovigilance (PV) data are crucial for ensuring safety and effectiveness of medicines after drugs have been granted marketing approval. This paper describes the PV systems of India, Uganda and South Africa based on literature and Key Informant (KI) interviews and compares them with the World Health Organization’s (WHO’s) minimum PV requirements for a Functional National PV Syste...

The solar photovoltaic (PV) systems are facing serious problems due to unavoidable losses in their system, leads to more devation of output power from the input power level. This effect is known as a mismatch effect and is available in PV systems. Many losses are encountered in PV system and it is difficult to minimize such losses. In this paper, the influence of thermal effect on the solar PV ...

Background & Aims of the Study: The quality of the edible oils is made with chemical compositions and percentage of  the degree of unsaturation fatty acids. The peroxide value (PV) always measures the extent of primary oxidation (rancidification) of oils. Oils Rancidity can produce potentially toxic compounds associated with health effects such as heart and neurological disorde...

Background: Pemphigus vulgaris (PV) is a rare autoimmune blistering disease of the skin and mucous membranes. Because vitamin D deficiency is associated with many immune disorders, we compared the levels of vitamin D between PV patients and healthy controls. Methods: Vitamin D level of 20 patients with PV was compared with 20 healthy individuals matched for age, gender, hours spent in the sun, ...

Background: Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are 2 inflammatory indicators that increase in many pathologic and physiologic conditions. Pemphigus vulgaris (PV) is an autoimmune skin disease in which autoantibodies against desmogleins cause acantholysis. In this study we have measured ESR and CRP levels in patients with PV to evaluate the relationship between an ...

Nowadays, Distributed Generation (DG), especially PV systems as a new source of power absorbed a high percentage of investment. Fault Detection and analysis in solar photovoltaic (PV) arrays are important issues to increase reliability, efficiency and safety in PV arrays. Due to PV’s non-linear characteristics, current-limiting nature, high fault impedances, low irradiance condi...

High-resolution two and three-dimensional numerical experiments are used to study the manner in which advection of potential vorticity (PV) by frontal instabilities growing out of an initially symmetrically unstable flow or forced by destabilizing wind-forcing constrains the extreme minima in the PV to values near zero. The instabilities act as a PV pump, upwelling high PV water from the pycnoc...

Maximum power point tracking controller is essential to obtain the maximum power from a solar array in the photovoltaic systems as the PV power module varies with the temperature and solar irradiation. In this paper, several methods for the MPPT of the PV systems are discussed and it can to be used as a Helpful reference for the upcoming MPPT user in the PV applications.
