The influence of nuclear polarization on the bound-electron g factor in heavy hydrogenlike ions is investigated. Numerical calculations are performed for the K-and L-shell electrons taking into account the dominant virtual nuclear excitations. This determines the ultimate limit for tests of QED utilizing measurements of the bound-electron g factor in highly charged ions.

In the recent work [1] we developed a relativistic method for evaluation of charge-transfer and electron-excitation processes in low-energy ion-atom collisions. Here we report on a recent application of this method for the evaluation of K-shell-vacancy production and K-K-shell charge transfer probabilities versus the impact parameters in lowenergy collisions of H-like ions with neutral atoms. T...

In this article, stream flow effectivness is based on hydraulic network studied in the shell-side of a shell and tube heat exchange as a case study. For an appropriate heat exchangers rating design to meet a specified duty, it's better to consider each stream flow separately. Using the hydraulic network principals, a set of the correlations for calculating different stream flow rates in the cro...

This paper has constructed a linear quadratic Bézier-like curve with two shape parameters. The proposed work is to design the Arabic fonts by using Bezier-like curves. focus of this study new functions and look at their application in designing fonts. Our procedures involve combination polynomial basis functions. rational non-rational are used modified as desired simply altering values paramete...

Shared memory many-core processors such as GPUs have been extensively used in accelerating computation-intensive algorithms and applications. When porting existing algorithms from sequential or other parallel architecture models to shared memory many-core architectures, non-trivial modifications are often needed in order to match the execution patterns of the target algorithms with the characte...

Micrometer-sized, monodisperse polystyrene (PS)/poly(styrene-co-sodium styrene sulfonate) (P(S-NaSS))/poly(n-butyl methacrylate) (Pn-BMA) composite particles having a ‘golf ball-like’ shape were prepared by seeded dispersion polymerization of n-butyl methacrylate with PS-core/P(S-NaSS)-shell seed particles with various shell thicknesses in the presence of dodecane droplets in a methanol/water (...

In Helisoma duryi, the periostracum is the outermost organic layer of the shell and it is secreted by the mantle collar. Addition of porcine insulin (0.1 μg/ml) to the incubation medium increases the incorporation of labeled amino acids in the mantle collar in vitro. The immunoblotting technique revealed two immunoreactive insulin bands with a molecular weight of 16 and 7 kDa in the hemolymph. ...

We consider boson stars and black holes in scalar electrodynamics with a V-shaped scalar potential. The boson stars come in two types, having either ball-like or shell-like charge density. We analyze the properties of these solutions and determine their domains of existence. When mass and charge become equal, the space-times develop a throat. The shell-like solutions need not be globally regula...

A microscopic model of the electromagnetic form factor of the nucleon is developed in a hadronic framework, including pions, nucleons and the ∆-resonance explicitly. The space like on-shell form factors are reproduced and predictions for the half off-shell dependence are made. The impact of this off-shell dependence in the time like sector (q 2 < 1 GeV 2 , thus including the region of vector me...
