Aims: In the present work we explore magnetic properties especially spin glass, antiferromagnetic and paramagnetic states of diluted magnetic semiconductors (A1-xMnxA' (A = Zn, Cd and A' = S, Te, Se)). Place: Department of physics, College of natural sciences, Addis Ababa Univers...
Nonequilibrium statistical operator (NSO) in the form suggested by Zubarev is represented as an averaging operation of the quasiequilibrium statistical operator over the distribution of the lifetime of the system. The form of the density function of the system lifetime affects al...
Corrosion in steel reinforced concrete structures has prompted researchers to work on alternative material to steel that are resistance to corrosion. This paper looked at the use of bamboo and rattan cane as alternative materials to steel in reinforced concrete struts. Fifteen (...
A theoretical investigation has been made of the roles of the degeneracy and the dynamics of electrons and ions on the DIA (dust ion-acoustic) Korteweg-de Vries (K-dV) and modified Kortewegde Vries (mK-dV) solitons that are found to exit in a dusty degenerate dense plasma contain...
In this paper, the modified double sub-equation method is proposed to construct complexiton solutions of nonlinear partial differential equations (PDEs). By means of this method, some new complexiton solutions to nonlinear PDEs are obtained, which are non-travelling wave and vari...
In this paper, electrical characteristics of Double Gate Metal Oxide Semiconductor Field Effect Transistor (DG MOSFET) and that of Gate All Around Silicon Nanowire Transistor (GAA SNWT) were investigated. In particular, the effect of channel length was studied. Full quantum mecha...
The phenomenon of thermal Spreading resistance takes places when two rough solids are brought into contact and heat flow is streamed across their asperities. The purpose of the present study is to investigate the heat conduction and thermal spreading resistance of Half-Spaces and...
The adsorption of 2,4-D (dichlorophenoxyacetic acid) in 4x10-4 and 10-3 mol/l aqueous solutions on carbonized chest nut shell (CCS) was studied at 25ºC. The effect of temperature was also studied at 25 and 35ºC for the concentration of 10-3 mol/l. The adsorption data was modelled...
Aim: The study assesses the qualities of contaminated soils of ten municipal waste dumpsites in Kaduna metropolis, Nigeria. Study Design: Physico-chemical parameters and heavy metals were analyzed in soils and plants of ten dumpsites across wet and dry season in Kaduna metropolis...
Prospective outdoor imaging depends on diurnal changes through the day and it needs an understanding of light and its effects on quality of the images. In this paper, investigations have been carried out to study the effect of diurnal changes on the quality of the images taken at...
The crystal structure of spiro[2.2"]acenaphthene-1"-onespiro[3.3']-5'-(naphthylmethylidine)-1'-methylpiperidin-4'-one-4-(naphthyl)octahydroindolizine has been elucidated by modern spectroscopic technique including, 1H and 13C NMR spectroscopy and unequivocally confirmed by singl...
In this paper, the modified simple equation (MSE) method is executed to find the traveling wave solutions for the (2+1)-dimensional modified KdV–Kadomtsev–Petviashvili (mKdV-KP) equation and the (2+1)-dimensional Painlevé integrable Burgers equation (PIB). The efficiency of this...
The conditions are identified under which the electrostatic image forces at an interface dielectrics result in spatial confinement of the large polarons. This paper presents the theoretical study of large polarons state near the interface of two insulators. Action of a combinatio...

During combustion of hydrocarbons with high viscosity there is a problem of their spraying. Traditional gasdynamic jets are not suitable for solving these problems. Therefore, the creation of new plasma-liquid systems that would allow effective spray hydrocarbons with high viscos...
Studying the influence of a nanoinclusion embedded in nanofiber reinforced composite alongside a nanofiber is the objective of the present investigation. The analysis is done based on 2D, linear elastic finite element through using finite element package ANSYS/Mechanical to explo...
