The present study aims to remove nickel ions from solution of the simulated wastewater using (Laminaria saccharina) algae as a biosorbent material. Effects of experimental parameters such as temperature at (20 - 40) C⁰, pH at (3 - 7) at time (10 - 120) min on the removal efficiency were studied.
Box-Wilson method was adopted to obtain a relationship between the above three experimental parameters and removal percentage of the nickel ions. The experimental data were fitted to second order polynomial model, and the optimum conditions for the removal process of nickel ions were obtained.
The highest removal percentage of nickel ions obtained was 98.8 %, at best operating conditions (Temperature 35 C⁰, pH 5 and Time 10 min).

Hartree-Fock calculations for even-even Tin isotopes using
Skyrme density dependent effective nucleon-nucleon interaction are
discussed systematically. Skyrme interaction and the general formula
for the mean energy of a spherical nucleus are described. The charge
and matter densities with their corresponding rms radii and the
nuclear skin for Sn isotopes are studied and compared with the
experimental data. The potential energy curves obtained with
inclusion of the pairing force between the like nucleons in Hartree-
Fock-Bogoliubov approach are also discussed.

This study was designed to compare the effect of two types of viral hepatitis A and E (HAV
and HEV) on liver functions in Iraqi individuals by the measurement of biochemical changes
associated with hepatitis.
The study performed on 58 HEV and 66 HAV infected patients compared with 28 healthy
subjects. The measured biochemical tests include total serum bilirubin, serum transminases (ALT
and AST) alkaline phosphatase (ALP) and gamma glutamyl transferase (GGT).
The study showed that adolescent and young adults (17-29) years, were mostly affected by
HEV while children (5-12) years were frequently affected by HAV. The severity of liver damage in
HEV patients was higher than HAV patients as a result of high serum transa

     This study was conducted on 30 birds (15 birds for each type) divided as 10 birds for each part of study. Anatomical part revealed that the small intestine in both birds kestrel (Falco tinniculus) and white eared bulbul (Picnonotic leucotis) formed from 3 segments; duodenum, jejunum and ileum with no clear demarcation line between them. In kestrel the Meckel's diverticulum appeared as small projection to separate between jejunum and ileum. Both ratio of intestinal length to body length and of intestinal weight to body weight was higher in bulbul than those in kestrel.  Histological study showed that the wall of all three parts of small intestine was composed of the same histological layers;

Amygdalin specifically represents the apricot (Prunus armeniaca) seed in the Rosacea family of plants. Except for cyanogenic glycoside, the seeds include a variety of substances, including trace minerals, vitamins, carbohydrates, organic acids, esters, phenols, and terpenoids. It is well known that bioregulators have the ability to control the activity of certain hormones and enzymes. The current study examined the effect of Iraqi apricot seed extract on physiological parameters in male rats, including blood parameters, hormone parameters, and antioxidant parameters, as well as histological studies of the spleen and testes. The study comprised four groups, each consisting of six animals. The animals in the control group received distille

Structural analysis is a branch of solid mechanics which utilizes straight forward models for solids. The main objective of Structural analysis is to find out the effect of loads on the physical structures and their components. A beam is a structure with a constant cross-section and is described by its significant length in comparison to its thickness and width. A cantilever, on the other hand, is a slender beam with a uniform cross-sectional shape that is fixed horizontally at one end and subjected to a load at the other end. Columns, which serve as vertical compression members in building frames, are susceptible to buckling and failure when subjected to relatively small axial loads. The analysis of loaded beams, cantilevers, and elo

        The sensor aspect is one of the most critical disciplines due to its wide application in life. This work has studied the performance of the Fe₃O₄ nanocomposite, which was prepared by the synthesis of Fe₃O₄ nanoparticles (NPs) by the co-precipitation method through its precursors, which are ferric chloride and ferrous chloride. On the other hand, graphene oxide was synthesized using the Hummers method. Chemical sensing is a process that converts a chemical or physical change of a specific analyte into a measurable signal whose magnitude is usually proportional to the concentration of the analyte. The chemical sensor is an analyzer that responds to a particular analyte and reflects

In this paper, we investigated the Bayesian estimation of the unknown parameter of the Inverse Rayleigh Distribution (IRD) under different priors, represented by the inverse gamma distribution, the inverse chi-squared distribution, and the standard Levy distribution as priors. We obtained the posterior distributions for the unknown parameter of IRD under the different priors based on the general entropy loss function (GELF). We assumed different values for the shape parameter of GELF. Also, the maximum likelihood estimator (MLE) is used to estimate the scale parameter of IRD. Then, a study is conducted to obtain the results, based on the different parameters of Inverse Rayleigh distribution and sample sizes. We found tha

This work has been done to prepare a series of new alkene compounds derived from 4-thiozolidinones by substituting different aldehydes, P-acetamido-phenol, and 2-mercapto-benzoimidazole, which were used as starting materials to form ester [I]_a,b and then make hydrazides [II]_a,b, which were used to prepare 1, 3, and 4-oxadiazoles [III]_a,b, which were then used for prepared Schiff bases [IV]_a-f, The next step was the synthesis of 4-thiazoldinone derivatives [V]_a-f  from Schiff bases. The final step was the synthesis of alkenes [VII]_a-f, the prepared derivatives were identified with spectral methods (FT-IR, ¹H-NMR, mass, and CHNS). The antibacterial activity of th

  The novel (La-PAA) of the ligand 8-[3-(pyrazoyl)azo]Adenine (PAA) was synthesized with the molar ratio (1:3), which was appointed by using the mole ratio method. The C.H.N.S elemental analysis, magnetic measurement, thermal analysis, and spectral methods (UV-Vis, FTIR, and HNMR) were employed to support the mode of binding and geometrical structure for ligand (PAA) and (La-PAA) complex. The FTIR and 1H N.M.R. spectral results showed that the (PAA) acts as neutral N, N-bidentate with La (III), as well as the absorption results in specific octahedral structures for (La-PAA) complex. The thermal decomposition of the (PAA) ligand and its (La-PAA) complex performed many steps, and the (La-PAA) complex is more thermal stable than the free l

The current study was conducted on six adult males of the Iraqi pin-tailed sandgrouse, Pterocles alchata, to determine the histological structure of the kidneys. The results showed that each kidney consists of three lobes: cranial, middle, and caudal. Histological results showed that the kidneys consist of the cortex and the medullary, and the cortex forms the majority of the kidney, which consists of large and small renal corpuscles. Each renal corpuscle consists of the Bowman capsule, glomerulus, the proximal convoluted tubule, which is  lined with simple cuboidal epithelium tissue with a brush border, the distal convoluted tubules, and the collecting tubules, which are lined with simple cuboidal epithelium tissue. The medull

        The surface disintegration of metals and alloys in a particular surrounding environment is known as corrosion, in addition to its chemical qualities, corrosion processes change the physical and mechanical properties of a metal alloy. A new approach based on a unique material has been employed to prevent rusting. Conducting polymer-composites are material types that show promise for anticorrosion by electrochemical synthesis of polylimonene/metals oxide nanocomposite (ZnO,TiO₂) on Stainless Steel 304L, which plays as the working electrode by using the electropolymerization technique. The synthesized coating polymer was characterized by Fourier transform-infrared spectroscopy and atomic force microscopy checkups.

      A new class of silicone polymers was synthesized based on dichlorodi(methyl)silane (DCDMS) with some organic compounds [M1-M6] containing terminal hydroxyl groups previously synthesized by different chemical reactions, and their nanocomposites were synthesized using silver nanoparticles (Ag-NPs). All polymers were synthesized using condensation polymerization and characterized by FTIR and ¹HNMR spectra. The biological activity of silicone polymer P5 was evaluated using different weights of silver nanoparticles (1%, 3%, 5%, and 7%) against Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive). The results showed that the higher the percentage of silver nanoparticles, up to 7%, t

Media studies have focused mostly on the issue of the mental image because the image that is formed in the mind has become not only a photo of a human being and having kept for himself. This image has an outside influence which may sometimes up to the formation of the fate of others and it sometimes includes individuals and groups together.
This study comes in the context of identifying the image of Iraqi political parties among Iraqi university students and the nature of the view that students have in their minds about these parties.
Chapter one includes the problem of the research, the importance of the study, the goals and method used. Chapter two is divided into two sections: section one deals with the concept of the mental i
