This work deals with the study of the morphodynamics, history of development of landforms and the origin of the Ga’ara depression. The depression is a suboval erosional topographic feature extending in E-Wdirection and located about 50 km north of Rutba Town, at the Western Desert of Iraq. The area is characterized by fresh and clean surfaces, scarcity of vegetation, abundance of rills, intense drainage and immature soil. These clues indicate that the erosion in the study area is effective. Four types of erosion features are recognized in this area namely sheet, rill, badland and wind erosion. The extent of the wind erosion depends on its position in relation to the prevailing wind direction. Water, wind and gravity are the main agents of erosion although the former seems more effective. In general, the valleys are dense in the hard rocks which indicate intensive erosion. Two types of drainage pattern can be distinguished in the study area, a dendritic pattern, especially at the exposure area of the Mulussa dolostone, and a centripetal pattern at the central part of the depression at the confluence of the main wadis. The valleys are V-shaped in their upper reaches and gradually change to flat-bottom shallow valleys in their lower reaches. Two major types of mass wasting are recognized, namely, rock fall and slump. Rock fall is the most common process whereby most of the talus accumulates at the base of the cliff. Slump is frequent at the south and southwestern rims of the depression. The slope surfaces are generally composite of the type free-face concave pediment. The depression is asymmetrical having steeper slopes in the south and thewestwhereas the northern and eastern scarps are wider and gentler, respectively. History of landform development is investigated in the Ga’ara area. Seven episodes are distinguished according to emergence and paleoclimatic conditions. The landforms of the study area were formed and further developed during the emergence episodes. The history of the development of the Ga’ara depression is studied too.
Indicators of government debt is of extreme importanse in economic activity through knowledge of the economic impact of government debt, if the phenomenon is accepted or prepared to dangerous stage by stage, and there fore it can Through these indicators to measure the degree of indebtedness in relation to the economic activity of the Government on the one hand, the governments ability to repay the other hand.
Due to this it inferred that the degree of indebtedness in Iraq specificratio has exceed 60% during the period 1990 – 2002 ntejh lack of political and economic stability of the government, which led to the governments inability to repay the ma

Among the most dangerous of these emergent phenomena, the phenomenon of suicide among young people of both sex, which has grown and increased in an unprecedented manner, surpassing all known social norms in Iraqi society and the prevailing religious values. Suicide in Iraqi society has transformed from a simple case to a visible presence in all Iraqi provinces. Suicides cases have registered in all cities of Iraq and of bo

From the study of climate reality of the basin between 1990-

that the annual rate of rainfall is 253.02 mm, the relative humidity

Histologically, the liver of marsh harrier was found to contain numerous lobules which are not well defined by the connective tissue of the septa except that surrounded the portal triads. The parenchyma of liver composed of irregular branching cords of hepatocytes organized in double rows alternating with tortures path sinusoids which are lined with flattened endothelial cells and large, irregular outlined kupffer cells. Hepatic cords arranged in a radial pattern around the central vein of the liver lobule while in a subscapsular region they run parallel to the ca
