The experiment was conducted to evaluate and performance comparison for moldboard and disk plows in central of Iraq in 2011. Three factor were used in this study included Two types of plows included moldboard and disk plows which represented main plot , three forward speeds of the tillage was second factor included 1.85, 3.75 and 5.62 km / h which represented sup plot , and three levels of soil moisture was third factor included 21 , 18 and 14 % to determined data actual plow depth , Practical productivity, Volume of disturbed soil, Field efficiency , Slippage percentage in silt clay loam soil with depth 22 cm were studied in the experiment Split – split plot design under randomized complete block design with three replications using Least Significant Design was used . Mold board plough recorded best practical productivity was 0.3118 ha/hr , volume of disturbed soil was 629.77 m3/hr and field efficiency was 59.85 % , while disc plough recorded higher actual plow depth 21.02 cm and slippage percentage was9.71 % . Increasing forward speeds of the tillage from 1.85 to 3.75 then to 5.62 increasing slippage percentage from 6.39 to 8.26 then to 12.22 % , practical productivity from 0.1421 to 0.2845 then to o.4180 ha/hr and volume of disturbed soil from 299.89 to 592.38 then to 838.24 m3/hr , while decreased actual plow depth from 21.13 to 20.86 then to 20.08 cm and field efficiency from 58.98 to 58.21 then to 57.07 % . with decrease soil moisture from 21 to 18 % decrease actual plow depth from 20.92 to 20.70 cm and slippage percentage from 10.58 to 7.29 % , and increase practical productivity from 0.2712 to 0.2923 ha/hr, volume of disturbed soil from 562.01 to 598.98 m3/hr and field efficiency from 55.94 to 60.31 % . While continues decrease from 18 to 14 % decrease actual plow depth from 20.70 to 20.46 cm, practical productivity from 0.2923 to 0.2811, volume of disturbed soil from 598.98 to 569.52 m3/hr and field efficiency from 60.31 to 58.01 % , and increase slippage percentage from 7.29 to 9.00 % .
This research focuses on necessary state to develop and strong the financial sector in Iraq by consider that it is allow to achieve the financial flexibility and the enough currency to encourage the investment and economic growth , this picture will be coming by take and obligation the international criteria by general agreement on trade in services (GATS) that it is one of agreements of world trade organization (WTO). This mater doing to strong the legal and legislation environment founded international confidential , by it , the institutions and financial sector in Iraq will be more active.

In this paper, a relationship between the liquid limit and the coefficient of consolidation of Iraqi soils are studied. The samples of soil used in study are undisturbed silty clay. These samples are taken from different locations and depths of Middle and South of Iraq by cooperation with Consulting Engineering Bureau- University of Baghdad- College of Engineering. The depth reached about 20 meters. The experimental work is made to calculate the liquid limit and the coefficient of consolidation. From these sites, 280 points are obtained. The relationship between the liquid limit and the coefficient of consolidation is drawn as a curve. This curve is studied and compared with the curve that obtained from other studies. From these curves, it

Investment in human capital of renewable energy can be relied upon to get to achieve the goals of development is important for Iraq through the intellectual community cards creative able to innovate and develop what is so is study the effect of human investment on economic growth through the adoption of the index of national income as a function of variables independent ( human capital, physical capital) and this is built on the premise that the relationship direct correlation between economic growth and human investment, and it can measure the return on human investment, which is an incentive to increase human capital through education and the development of the economy in general have shown th

The Iraqi economy has suffered for a long period of inflation because of the Iraq war and the resolutions and the sanctions that were imposed on Iraq, this phenomenon overshadowed at various aspects of the economy including the tax revenue that the State seeks to optimize the total income for the budget, the research covers the years 1990-2010, these years have been divided according to the country's economic variables.
The research adopted on econometrics analysis that is based on the information and data available on topics and has been using statistical methods to test functions are formulated.
Research concluded that rates of inflation and GDP impact is limited to direct taxation and indirect in current prices a

The developing countries can be distinguished by spatial disparities and by this a wide gap between urban and rural settlements were produced as well as the appearance of primate cities. The effect of spatial development as a dynamic and continuous process can be perceived in the state of population distribution inside settlements inter and intra regions as well as the hierarchy of urban settlements according to time series. The research proved that the improvement judgment of the structure of the urban system using Gene factor is not accurate because it cannot be accounted for the internal components of the system which make a contrariety between the whole judgment (country) and partial components (Provinces including Sulaimaniy
