In this experimental study three cement samples were collected from different shops
and the samples were labeled as CMSX, CMSY, and CMSZ . A 527,554.8 and
505.29gm of cement samples were weighted and sealed in the same ...
The effects of particle shape on the polarizability, absorption coefficient, and absorption cross sections of randomly oriented particles as the function of distribution
function are studied in the Rayleigh limit. In ...
Probably, one of the earliest outstanding theoretical prediction of General Relativity is the existence of black holes resulted from stellar collapse on self gravitation.
However, more than a dozen of decades has passed ...

Irrespective of whether Active Galactic Nuclei (AGN) is cored with Supermassive Blackholes (SMBH)or not, there is a general consensus that observations indicate that the AGN
plays role in hosting galaxy evolution. The ...
This study attempts to apply ordinal logistic regression to identify the determinants of women
nutritional status using the data of data of Ethiopian Demographic and Health survey 2011.
Based on body mass index nutritional ...
The electronic and structural properties of Iron (Fe) were investigated using density functional theory (QUANTUM ESPRESSO). Iron is the main ingredient used to
make steel and the crystalline structure is body center cubic ...
Nickel is a metal which is widely distributed in nature; and it is found in animals,
plants, and soil. The density functional theory (DFT) simulation tools were employed
to investigate energies, magnetization and geometrical ...
The Schwarzschild solution is unique and its metric can be interpreted as the exterior
gravitational field of a spherically symmetric mass. Most of the experimental tests
of general relativity were based on the Schwarzschild ...
In this work the binding energy per nucleon of isotopes with nucleon number less or equal
to twenty, i.e for those isotopes which lie inside or near to the second closed shell has
been calculated. The objectives of the ...
The behavior of thermoluminescence glow curve properties of KY3F10 : H3+
o phosphor in view of second order kinetics was studied. Kinetic parameters of the glow
curves used to determine the activation energy (E) the ...
Density functional theory (DFT) has had a rapidly growing impact not only on fundamental but also industrial research. The local density approximation (LDA) and
the generalized gradient approximation (GGA) were used to ...
In this thesis,the thermoluminescence glow curves of zinc oxide has been investigate
theoretically in view of general order kinetics.The effects of various thermoluminescence kinetic parameters such as the activation ...
In this work, we have employed for the analysis of TL glow curves of KY3F10 : Ho+3
material. The continuous promotion in numerical methods has greatly helped to
solve the complex TL kinetic equations (rate equations) ...
In this thesis we analyze a nondegenerate three-level cascade laser with cavity mode
coupled to a two-mode squeezed vacuum reservoir with the aid of master equation, We obtain the stochastic differential equations associated ...
Currently, the science of astronomy for the study of origins and evolutions is advancing both theoretically and observationally. However, there are a number of works
for further developments. For example, the data extracted ...
An unsteady double diffusive mixed convection boundary layer flow over a vertically stretching sheet in the presence of suction/injection is investigated in this paper. The governing partial differential equations are ...
As stellar astrophysics has developed, attention has increasingly become focused on the details and re nements that make the current models of stars so quantitatively accurate. Despite the fact that, there is an overall ...
The present generation scienti c status in broad, generally or otherwise with speculation historically linked to the open sky observations and the physical interpretations of the phenomena, "Astronomy of the ancient people." ...
In this research analytical and numerical calculations have been made to identify
the dependence of third order nonlinear refractive index and absorption coefficient
on optical laser intensity and transition energy. ...
In this work, calculations of the excitation function of alpha particle induced reaction on zinc isotopes 64 Zn and 66 Zn below 46 MeV have been studied. The theoretical cross-section induced by alpha-particle on zinc ...
