Partial shadowing has been identified as a main cause for reducing energy yield of grid-connected photovoltaic systems. The impact of the applied system configuration on the energy yield of partially shadowed arrays has been widely discussed. Nevertheless, there is still much confusion especially regarding the optimal grade of modularity for such systems. A 5-kWp photovoltaic system was install...

www.aafp.org/afp Volume 87, Number 10 ◆ May 15, 2013 Among adults with atrial fibrillation, the annual rate of stroke ranges from 1 to 20 percent, depending on comorbidities and the patient’s history of cerebrovascular events. Because of the risk of bleeding associated with antithrombotics such as warfarin (Coumadin) that are used to reduce the incidence of atrial fibrillation–related stroke, i...

A novel condensed polynomial neural network using particle swarm optimization (PSO) technique is proposed for the task of classification in this paper. In solving classification task classical algorithms such as polynomial neural network (PNN) and its variants need more computational time as the partial descriptions (PDs) grow over the training period layer-by-layer and make the network very co...

For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...

this survey has been conducted to indicate the positive effects of implementing neonates continuous care patterns on their physical health as well as early diagnosis and decrease of complications in 6 weeks after delivery. this quasi-experimental study has been conducted on 118 mothers and their neonates in one maternity hospital in iran. neonates were assigned in control and experimental group...

in postpartum departments the skills and experience of doctors and midwives will overlap together but it is not sufficiently recognized . little importance to the ability of midwives will reduce the scope of their responsibilities and decision-making power will be taken from them , also this will result in demoralization and decreasing job satisfaction. in this situation work load of new physic...

objective: early discharge of newborns is essential because of social, economic an medical reasons in our area, but it increases readmission rates especially for hyperbilirubinemia. hence, predicting the high risk neonates for subsequent hyperbilirubinemia is required. this study was designed to investigate which level of total serum bilirubin (tsb) at the first day could be used to predict hyp...

BACKGROUND Factors associated with the development of atrial fibrillation (AF) in general population have been described, but it is still unknown whether the same risk factors apply to heart failure (HF) patients. The aim of this study was to identify clinical factors related to various forms of AF in HF patients. METHODS The clinical and echocardiographic characteristics were assessed in 155...
