The present work include preparation and characterization of ethane dial bis [(5-methyl-1,3,4-oxadiazol-2-yl)hydrazine] as ligand ,the new complexes were prepared from the reaction of ligand with the transition metal salts (CuCl2.6H2O, NiCl2.6H2O, CoCl.6H2O, FeCl3.6H2O, CrCl.6H2O). The elemental analysis (C.H.N), Mass spectra, Infrared(IR) spectroscopy, Nuclear Magnetic Resonance Spectroscopy (1H-NMR), UV-Visible spectroscopy and molar conductivity techniques were used to characterize the structure formula of these ligand and their complexes. The complexes of [Cr(III),Fe(III),Co(III)] for ligand have shown octahedral configuration. Complexes of Ni(II) and Cu(II) have shown tetrahedral configuration, Semi-empirical method was used for calculating the Infrared spectra for the ligand and their complexes. A comparison with the experimental data has also been done. The Semi-empirical PM3 method was used in calculating the total energy (binding energy, complexation energy and the enthalpies of formation), bond length for the ligand and their metal complexes

In this work, we generalized the concepts of fuzzy ideal and r-fuzzy local function in fuzzy ideal topological space in view of the definition of S ̌ostak to fuzzy soft topological spaces. Also, we proved some results and connections among them

This study aimed to study chromosomal changes for people who eat frozen meat, the samples were collected from 30 people (males) aged 20-25 years from three different regions, they divided between , the city center and districts and rural areas in addition to control group who were 10 healthy people in the same sex and age and didnt eat frozen meat. Were prepared chromosomes from lymphoid peripheral blood cells, and then calculated changes in the chromosomes . The results of the study showed the presence of abnormalities in the chromosomes of people who lives in city center(third group) as compared to control where it reached 0.13 , but this different was not significant at the level (p <0.01) changes of chromosomal aberration in first and second groups were 0.11 , 0.09 , but did not constitute significant differences. The types of malformations observed in the chromosomes of the study samples included : chromatide breack, chromatide delete , acentric fragmentes showed no numerical changes in the studied groups

The electrochemical behavior was investigated of Lignin Resin by using the cyclic voltammetry technique. Such investigation mainly focuses on the expected properties of the doped resin with different doping ratios of Rhodamine B (0.01, 0.5, 0.1, 0.15, 0.2) %wt. This is indicated by the electron transfer between the dopant and resin, which clearly shows the appearance of oxidation – reduction peaks accompanied log increase in electrical current Ip as applied potential changes. The heights of Ip oscillate due to the change in scan rate . The results of linear of relationships between Ip with 1/2 indicated that the electron transfer was a process of one electron transfer

In the current study the authors aimed to investigate the effect of anti-venom of Echis carinatus on hematological and hormones parameters as well as explore its influence on liver enzymes of male rats. Mature adult rats were divided into three groups 6 animals for each group. IP injected method was used. First group (Control group) injected with normal saline (0.9%Nacl), Two group injected with (0.25ml/kg) of anti-venom for two times, and the third group injected with (0.5ml/kg) of antivenom for two times. Animals killed within 24 h.

In the present study, a numerical investigation has been made to predict the laminar flow and heat transfer through a rectangular channel with adiabatic, different configuration obstacles which are arranged alternately on the upper and lower walls of the channel. These walls are subjected to a constant heat flux 500 W/m2. The effect of obstacles number, and obstacles shape on the flow and heat transfer characteristics with different Reynolds number (100,200,300,400,500,600and 700) have been studied. The continuity, momentum, and energy governing equations are solved by the finite volume method. The results of this study reveal that the obstacles have an obvious effect on parameters of the flow and heat transfer enhancement. The heat transfer is improved more as the obstacle's number increase. Further that, using rectangular obstacle leads to increase heat transfer rate higher than the rest of shapes for all Reynolds number tested.

Abstract This aims of this research is to study the effect of all transportation activities through lean and green management perspective. AL-Kufa /Iraq Cement plant is considered as a case study to examine the effect of individual and overall results that may contribute in the lean-green integration. Life cycle assessment was used as an environmental key performance indicator for lean green integration. Relationship matrix, Pie, and Pareto charts were tools and techniques used to assess the present results. Results were generated using Minitab Version 17 and Edraw Max. Version 7 software. Results showed that the material transported throughout processing was crucial in effecting on lean green integration not the transportation media. Since the same transportation media could be, synergistic, or conflicting according to position of this media to the process and relative material type transported. Results also show that transportation activities, throughout grinding resulted particulate matters that causes winter smog environmental impact. Thus human health impairments (Hi) damage in this transportation activity resulted 42.94 %. Followed by kiln production and cooling by 25 %. The rest value was divided between packaging, and finish grinding processes.

Forty specimens of house shrew Suncus murinus were collected from several localities in center of Nassiriyah city, Thi-qar Province for the period from February to July 2008. The animals were examined for helminth parasites. 23(57.5 %) to be infected with three species of helminths, two cestodes Staphylocystis furcata, S. multihamata and one nematode Pseudophysaloptera petaloidi. The measurements of the isolated parasites were taken and compared with previous studies carried out in the world. All these helminths were recorded in the present study for the first time in Iraq.

This research is aimed at investigating the hepatotoxic effect of hydrogen peroxide and effects of Curcuma longa and zingiber officinale on this hepatotoxicity. In present study we administration hydrogen peroxide to animals rat for induced high cholesterol in blood and caused liver damage . These were carried out via estimation of liver function tests and histochange in the liver. Fourteen adult Westar rats Rattus norvegicus were used for the experimental investigations. They were grouped into four groups:. Animals in group one served as the control group. Group two consists of rats administered with hydrogen peroxide (1% body weight) .Group three consists of rats administered with hydrogen peroxide and Curcuma longa (200 mg/ kg body weight).Group four administered with hydrogen peroxide and zingiber officinale(200 mg/ kg body weight). All animals administration orally, the experimental period lasted for 30 days. The rats were sacrificed on the thirteen day. The blood samples collected by cardiac puncture and placed in appropriately labeled bottles for the various assays. And section of liver isolated. There was a decrease in the aspartate aminotransaminase level, alanine aminotransferase level are significantly lower (P<0.05) in the rats of the control group than both the rats treated with hydrogen peroxide only and the ones treated peroxide with Curcuma longa and peroxide with zingiber officinale These were lower in the rats treated with Curcuma longa and zingiber officinale than the rats treated with hydrogen peroxide alone. These reduction is however not statistically significant and it presents that these could be dosage related. The histological change in the section of liver showed as clusters of inflammatory cells surrounding portal area or within the parenchyma was seen. Vacuation within hepatocytes and congestion in centeral vien were observed and was generally necrosis hepatocytes compare compared with animals treatment in extracts a decreasing in degenerative changes was noticed in proxide + curcuma extract, there was a moderate decreasing of hepatocellular damage and portal tract fibrosis, inflammatory infiltration compared to peroxide group .But in the fourth group zingiber +hydrogen peroxide no hepatocellular damage,. It was noticed that this group has the same histological appearance as the control group. These results indicate that hydrogen peroxide is induce to increase the cholestrole and caused hepatotoxic but that Curcuma longa and zingiber officinale may be a protective effect on this hepatotoxicity.

The current study was conducted for the period from September 2015 until August 2016 in college of Education for Pure Sciences - University of Thi- Qar, this study aimed to fallow the changes on the External morphology features at different Embryonic Developmental stages when the pregnant mice treated with different doses of Dexamethasone (Dex). Use In the current study, sixty pregnant mice were randomly divided into four groups and each group of 15 pregnant mice. Given the members of each group specific dose of Dex and at different time periods, while the control group injected with a solution of Normal Saline 0.9%, all animals received doses used by tail intravenous injection until the end of the time periods specified. The treatment of animals under the same conditions were determined dose based on body weight, according to what is stated in the pharmaceutical constitutions. The results of statistical analysis at the level of probability (p<0.05) to different doses Dexamethasone show there is an negative effects on mice embryo's body weights and the lengths increase with increasing of number and doses concentrations. using of different doses of Dex showed various changes on general external morphological features and congenital malformation in embryos of treated mothers included: Death of embryos , Letter C Shape Embryos , Head hemorrhage , placenta damage , Neural Tube Defect, Trunk Torsion, curved head , Brain hypertrophy , Liver Hypertrophy , swelling , Short nostril and limbs, Convoluted Tail, Oedema ,Wrinkled skin, absent fingers and eyelids, Crooked pave, Short toes, Seal legs appearance , Tail congestion , Bulging eyes.

Two identical of double slope solar stills with same specifications were designed to study and improve their productivity to produce fresh water (drinking water) from salty water especially in the regions where the fresh water is low or unavailable such as south of IRAQ.
One of the two solar stills was subjected to modifications in order to increase the productivity of drinking water and to compare with non-modified solar still. Covering the basin of solar still with black piece of cloth increase the productivity up to( 22.35 percent). By adding charcoal powder on top of black piece of cloth the productivity was increased( 34.21 percent). However, the productivity was increased to (16.69 percent) when two reflections mirror was used.
Also, thermal efficiency of solar still was calculated. The highest value of( 34.13 percent) was achieved when modifications applied.
In this project, the chemical and physical properties of the water before and after distillation were analyzed. The double slope solar still produced fresh and drinkable water
