Introduction: One of the major causes of image non-uniformity in MRI is due to the existence of non-homogeneity in RF receive and transmit. This can be the most effective source of error in quantitative studies in MRI imaging. Part of this non-homogeneity demonstrates the characteristics of RF coil and part of it is due to the interaction of RF field with the material being imaged...
this paper presents a new method called vespiary regular hexagonal (vrh) model to calculate parasitic capacitance between conductor wire filaments of one turn of a coil and between conductor wires filament and liner and also total capacitance of n-turns having single-layers, multi-conductor wire filaments of the helix magneto cumulative generator (mcg) coil. the presented method is an analytica...
Computer modeling for the design of inductors for different applications in the induction heating process often seems to be necessary to save costs caused by the trial and error. In this paper, the effects of the number of loops in the induction heating process with the numerical solution of the Maxwell equations have been investigated using finite element method (FEM) and the COMSOL MULTIPHYSI...
This paper presents a new method called vespiary regular hexagonal (VRH) model in order to calculate parasitic capacitance between conductor wire filaments of one turn of coil (OTC) and between conductor wire filaments and liner and also total capacitance of one turn of the helix magneto flux cumulative generator (MCG) coil include single-layer conductor wire filaments in form of rectangular cr...
background: there is very little information about the mosquito fauna of qom province, central iran. by now only three species; anopheles claviger , an. multicolor , and an. superpictus have been reported in the province. to study mosquito fauna and providing a primary checklist, an investigation was carried out on a collection of mosquitoes in this province. methods: to study the mosquito (dip...
Informed by the theory of developmental origins health and disease, we conducted a survey among 66,854 mother–preschooler dyads in all kindergartens within Longhua District Shenzhen China for exploring combined effect prenatal mosquito coil smoke (MCS) exposure early postnatal nutritional status on obesity preschoolers. A self-administered questionnaire was completed mothers to collect parents’...
Objective: This study aimed to assess the current community’s perception status of dengue fever in (Yuhana Abad) slum area Lahore.
 Method: A quantitative cross-sectional was conducted Yuhana Abad, a suburb Lahore, Pakistan. It is largest majority Christian city with about 200,000 inhabitants. To determine people structured questionnaire used collect data and 384 households selected throug...
introduction: traumatic arteriovenous fistula (avf) called to an abnormal relationship between artery and vein which occurs in 10% of arterial traumas. if treatment of avf due to trauma delayed, different outcomes including heart failure, varices and varicose ulcers may accure. in case of chronic traumatic avf, open surgery may lead to remarkable outcomes, presence of many lateral veins and var...
