This paper demonstrates how the evaluation of the electromagnetic scattering from 3D rough multilayers can be analytically conducted in the framework of the Volumetric Perturbative Reciprocal Theory (VPRT). The advantage of the proposed approach is twofold. Indeed, in this framework the pertinent closed-form (first-order) scattering solution is derived in a conceptually clean way and is directl...
We discuss effect of nuclear shadowing in neutrino deep-inelastic scattering in terms of non perturbative parton model. We found that for small Bjorken x and large Q2 the structure function F3 is shadowed in nuclei about two times as stronger as F2. The underlying reason and phenomenological aspects of this observation are discussed. Key-words: neutrino, deep inelastic scattering, nuclear effec...
In recent years, we constructed a microscopic optical potential (OP) for elastic nucleon-nucleus ($NA$) scattering using modern approaches based on chiral theories the nucleon-nucleon ($NN$) interaction. The OP was derived at first order of spectator expansion in Watson multiple theory and its final expression folding integral between $NN$ $t$ matrix nuclear density target. Two- three-body forc...
4, 10- Dinitro-2, 6, 8, 12- tetraoxa-4, 10- diazaisowurtzitane (TEX) is well known as an efficient Insensitive high explosive. It was usually prepared via nitration of 1, 4- diformyl- 2, 3, 5, 6- tetrahydroxy piperazine reaction using a mixture of fuming nitricacid and concentrated sulfuric acid. However, these traditional liquid acids are toxic, corrosive and produce hazardous waste. In additi...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Elliptic flow of hard partons (P > 5 GeV), squeeze-out of soft partons (P ≤ 5 GeV) and produced particles are predicted in the framework of the HIJING model. They are caused due to jet quenching and heterogeneity of the interaction region. Collective flows of produced particles and nuclear fragments in nucleus-nucleus interactions have been studied for the last 15 years (see the latest reviews ...
Most high energy collisions can be described by a single hard scattering. By studying the single scattering, we can extract the parton distribution functions and test the short-distance dynamics of strong interactions. The normal parton distributions have the interpretation of the probability distributions to find a parton within a hadron. On the other hand, in order to study quantum correlatio...
The paper addresses the effects of Soret on unsteady free convection flow of a viscous incompressible fluid through a porous medium with high porosity bounded by a vertical infinite moving plate under the influence of thermal radiation, chemical reaction, and heat source. The fluid is considered to be gray, absorbing, and emitting but non-scattering medium, and Rosseland approximation is consid...
