one of the most dazzling events in the atmosphere is lightning. during updrafts in the life cycle of cumulus clouds, collision of graupels and ice crystals in the presence of liquid water results in vertical separation of electrical charges and lightning. there are four types of lightening depending on the location of discharge. the first type is cloud-to-ground lightning or fork lightning that...

Multidielectric polyethylene is a material that is generally employed as insulation for  the HVDC isolations. In this paper, the influence of temperature on space charge dynamics has been studied, low-density polyethylene (LDPE) and Fluorinated Ethylene Propylene (FEP) sandwiched between two electrodes were subjected to voltage application of 5kV (14.3 kV/mm) for extended duration of time ...

 Studies of phenomena such as charge, orbital and spin ordering in manganite has attracted much interest in recent years. These studies have been possible from an experimental point of view by the third generation synchrotron sources. X-ray with high flux density, tunable energy and polarization can be produced in synchrotron sources. Experiments have shown a resonant in peak intensity originat...

this paper examined the charge of circulating assets in common law jurisdiction. the aim was to know the way and basis that it is constituted and to find out its profits for creditors and also to find out its meaning and its impacts in market. the conclusion was that floating charge provides an appropriate security and benefits for the chargee and chargor, where chargee can achieve his benefits...

In this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. The electrochemical properties of the produced electrode are studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques in 3M NaCl, NaOH, and KOH electrolytes. Scanning electron microscopy (SEM) is used to characterize the mi...

In the present work, the transition matrix elements as well as differential and total scattering cross-sections for positronium formation in Positron-Hydrogen atom collision and hydrogen formation in Positronium-Hydrogen ion collision, through the charge transfer channel by Two-Centre Close-Coupling method up to a first order approximation have been calculated. The charge transfer collision is ...

  Background and Aim : The charge nurse role has received little attention in the nursing literature when compared with other nursing leadership positions. Although many hospitals have charge nurse position, there is a lack of clear guidelines concerning the role, competencies needed for optimum role performance, and criteria for evaluating performance. The aim of this study was to determine co...

In this paper, the penetration process of the follow warhead in anti structure tandem projectiles is investigated by numerical and experimental methods. These projectiles are usually shaped charge or EFP. In the follow projectile, geometry and material are considered as the two main parameters. Numerical modeling of the problem has been performed in AUTODYN code. The numerical results have ...
