The experiment was conducted in twodifferentsplaces, one of this experiment in the field was not under salt stress and the other experiment field was under salt stress.Those experiments were conducted in college of AgricultureDiyalaUniversity atautmyseason (2015 - 2016)to study the salt stress by usingseeds soaking with Hydrogen Peroxide and foliar application in different concentrations ofAbscisic acid.The experiment statistical design as RCBD was with three replicates.Soaking the seeds withHydrogen Peroxidetreatments 0 , 10 , 15 , 20 mmol.L-1. Three Abscisic acid levels0 , 15 , 30 mg.L1.α -Tocopherol, Catalase Enzyme, Membrane Stability Index,proline content, leaves area andpercentage of Electrolyte Leakage of Wheat, were measured. Results drawn from these were as follows: The α -Tocopherol concentrations, Catalase Enzyme,Proline content and percentage of Electrolyte Leakageincrease withsalt stress for soil,comparing with soil not under salt stress. The results showed that fourth level of Hydrogen Peroxide Soaking(20)superior on the levels (0)of α-Tocopherol concentrations, Catalase Enzyme,Membrane Stability Index, proline acid concentration and leaves areaincreased in values(78.88%, 135.54%, 17.47%, 34.04% ,16.36%) respectively with soil under Salt Stress.The results show increase in α-Tocopherol concentrations, Catalase Enzyme and percentageof Electrolyte Leakagewith low amount of Abscisic acid sprayingABA0(0 mg.L¹)comparing with the ABA1(15 mg.L-¹)and ABA2(30 mg.L-¹),but the treatment of spraying abscisic acid outperformedsignificantly increasedin the Membrane Stability Index anproline acid concentrationin leaveswith increase at the level ofABA2(30 mg. L-1)compareing with the other levels ofin the soil under salt stress. Theα-Tocopherol concentrations and Catalase Enzyme wereincreasedsignificantlyby interaction between(20mmol.L-1H2O2 +0 mg ABA. L1) comparing with the other levels in the soil that was under salt stress. . The Catalase Enzyme increase in the level(20 mmol.L-1H2O2 + 0 mg ABA .L-1) in the soil that was not under salt stress.Interference between (20 mmol.L-1H2O2+30mgABA.L-1) showedinsignificant effect on the Membrane Stability Indexandproline acid concentrationsin leavesat the soil that was under salt tension and proline acid concentrationsat leaves in the soil which was not under salt stress.Also most of characters in plant were significantly influenced by Hydrogen Peroxide under salt stress.
General survey for wheat rust diseases in Iraqi fields was done during the seasons of 2010, 2011 and 2012. The survey covered different fields in southern, middle and northern regions. Results of the first season indicated that most of Iraqi cultivars such as Tmmoze2, IPA 99 and Mexipak showed different types of susceptibility to both yellow and leaf rust infection. Disease severity increased when the conditions were favorable for infections with using susceptible cultivars. The severity of leaf rust was less in the north region comparing with the middle and south regions. Most of the introduced cultivars such as Sham6 and Cimmyto showed susceptible reaction to yellow and leaf rust. Yellow rust was in epiphytotic form at the Iraqi-Syrian-Tu

The percent work was designed to determine the effect of ginger plant aqueous extract on function and histological structure of kidney in mice treated with carbon tetrachloride (CCl4). Ginger plant caused a protective effect against CCl4 induced kidney damage and improved the kidney weight and biochemical parameters including urea, uric acid and creatinine. The ginger plant has a protective effect against injury in the kidney of mice treated with CCL4, because the ginger plant protects the tissues of kidney from toxic effect of CCL4. The kidney of CCL4 treated mice showed many histological alterations in the kidney included: atrophy, vascular degeneration and hemorrhage, death cell, degeneration of epithelial cells, destruction of basement

The successful insertion of a biocompatible material into living tissue with little to no evidence of rejection has revolutionized medicine and dentistry. An increase in bone response was observed with local administration of growth hormone around dental implants. Growth hormone may act as a bone stimulant in the placement of endosseous dental implants and enhances osseointegration. The aim of the study was to evaluate immunohistochemically the effect of the topical application of growth hormone on the osseointegration of cpTi implant. Materials and Methods: Eighty titanium screw implants were inserted in the tibia of the forty adult rabbits.

In addition, the production and marketing of Iraqi oil continued since 1934 and until the present time. Over the past eight decades, the range of economic benefit of the financial Iraq’s oil resources varied according to the applicable forms of investments in the oil sector in Iraq.

A computational investigation is carried out in the field of charged –particle optics with the aid of numerical analysis method using the personal computer. The work is concerned with the design of electron gun with space-charge effect. The Finite element method (FEM) used in the solution of Poison's equation for determine the axial potential distribution of the two-electrode immersion lens operated under zero magnification condition , and from the solution of the paraxial ray equation the optical properties such as the focal length , spherical and chromatic aberration coefficients are determined, also a calculation of the brightness and perveance for the lens. The electrodes geometry was determined in two and three dimensi
