Histological Structure of the Kidney in the Iraqi Weasel, Small Asian Mangoose, (Herpestes Javanicus ) (E.Geoffroy Saint.Hilaire,1818)
...Show More Authors

The present study aims to describe the histological structure of kidney of, (Herpestes javanicus ) that inhabits Iraqi lands. Transverse sections of kidney stained with hematoxylin and eosin showed two distinct regions, the outer thin darkly stained cortex and inner thick lightly stained medulla, which further subdivided into external and internal medullary zones linked with one conical renal papilla. The lateral margin of the outer medullary tissue forms a secondary renal pyramid with a specialized fornix. All the nephrons in the kidney start with the renal corpuscle [Malpighian], which is formed from two distinct parts, these are a centrally located glomerulus, which represented by a tuft of blood capillaries and an outer Bowman’s capsule which is distinguished by its cup structure that lined by a double thin epithelial layers of flattened squamous cells with urinary space separated between them. The epithelial cells of the Proximal and distal convoluted tubules have cuboidal shape but in the first tubules these cells are characterized by the presence of moderate to tall microvilli formed the brush border covering the luminal surface. Thin segment lined with flattened cells and found in large number in the medulla interna which indicate the presence of many nephrons with long loops of Henle. Well-developed vascular network was observed in the kidney tissue and a small to medium vascular bundles of vasa recta distributed in alternative fashion with uriniferous tubule bundles in the medulla externa. The terminal portion of papilla is lined externally by transitional epithelium which progressively towards the upper portion was changed first to simple cuboidal and then to flattened type.

Investigation of halo structure of neutron rich 14B, 15C, 19C and 22N nuclei in the two body model
...Show More Authors

The two body model of (Core+n) within the radial wave functions of the cosh potential has been used to investigate the ground state features such as the proton, neutron and matter densities, the root mean square (RMS) nuclear proton, neutron, charge and mass radii of unstable neutron-rich 14B, 15C, 19C and 22N nuclei. The calculated results show that the two body model with the radial wave functions of the cosh potential succeeds in reproducing neutron halo in these nuclei.

The Extent of the Practice of Iraqi Banks to Manage Profits Using the (LLp it) Model and Its Reflection on the Tax Base, A Case Study of A Sample of Iraqi Private Banks Listed in The Iraqi Stock Exchange
...Show More Authors

The research aims to identify the extent to which Iraqi private banks practice profit management motivated by reducing the taxable base by increasing the provision for loan losses by relying on the LLP it model, which consists of a main independent variable (net profit before tax) and independent sub-variables (bank size, total debts to total equity, loans granted to total obligations) under the name of the variables governing the banking business. (Colmgrove-Smirnov) was used to test the normal distribution of data for all banks during the period 2017-2020, and then find the correlation between the main independent variable sub and the dependent variable by means of the correlation coefficient person, and then using the multiple

Effects of Sandy Soil-structure Interaction on the Natural Period of RC Building Frames
...Show More Authors
Abstract<p>Building natural period, T, is a key character in building response for wind and seismic induced forces. In design practice, the period, T, is either estimated from empirical relations proposed by the design codes or determined from analytical or numerical models. The effect of the soil-structure interaction is usually neglected in the design practice and analysis models. This paper uses a sophisticated finite element simulation to investigate the effect of soil-structure modeling on the fundamental period of RC buildings subjected to wind and seismic induced forces. A typical interior building frame has been imitated using the frame element for beams and columns with constrains to mo</p> ... Show More

Investigation of the nuclear structure of 84-108Mo isotopes using Skyrme-Hartree-Fock method
...Show More Authors

Over the last few decades the mean field approach using selfconsistent
Haretree-Fock (HF) calculations with Skyrme effective
interactions have been found very satisfactory in reproducing
nuclear properties for both stable and unstable nuclei. They are
based on effective energy-density functional, often formulated in
terms of effective density-dependent nucleon–nucleon interactions.
In the present research, the SkM, SkM*, SI, SIII, SIV, T3, SLy4,
Skxs15, Skxs20 and Skxs25 Skyrme parameterizations have been
used within HF method to investigate some static and dynamic
nuclear ground state proprieties of 84-108Mo isotopes. In particular,
the binding energy, proton, neutron, mass and charge densities
