The aim of this work is concerned with detailed study of transfer of ozone into water.. Since ozone cannot be stored or conveniently purchased by the gram, pound, gallon or ton, it must be produced on site as needed, (where needed and when needed). The process will carried out with two important assumptions; first that ozone is the only active species that physically dissolves in water. And second that there is no chemical reaction .the process carried out in a perforated sieve tray column with 1 m long and 33 cm diameter. The effects of process variables such as (Water flow rate, pH and air flow rate which is refer to the concentration of free ozone in the gas phase in the absorption column). The result show that the absorption rate inc

Constant source and doublet singularities with Drichlet boundary condition are used on the body surfaces. Distance and setting angle changes of the tail are studied to predict the air flow characteristics. Since the flow is incompressible non-viscous (potential flow), the results obtained contain a large physical evidence and may give a good design tool for aircraft stability consideration. A FORTRAN program was built to calculate the flow characteristics and then validated with published data. Highly acceptable results are obtained as compared with these data, so that; the program can be used for discussing the des

Melatonin has been implicated in some pharmacological effects including sedative/hypnotic, anticonvulsant activity and others. The aim of this study was to investigate the antinociceptive effect of different doses of melatonin administered i.p. to mice, and then, to find the dose- response line of melatonin in mice as analgesic agent.
Methods: The dose response effect of melatonin (10, 50, and 100mg/kg) were assessed against control using tail flick test in mice as a model of nociceptive pain. In this model, all doses of melatonin were given intraperitoneally
The study aims to discuss the relation between imported inflation and international trade of Iraqi economy for the period (1990-2015) by using annual data. To achieve the study aim, statistical and Econometrics methods are used through NARDL model to explain non-linear relation because it’s a model assigned to measure non-linear relations and as we know most economic relations are non-linear, beside explaining positive and negative effects of imported inflation, and to reach the research aim deductive approach was adopted through using descriptive method to describe and determine phenomenon.

The Iraqi Government had used all Possible methods of financing the fiscal deficit according to the economic and Political Circumstances at the time. It had borrowed from abroad during the 1980s. Those methods of borrowing led to negative impacts on the Iraqi economy such as increased external dept burden, higher inflation rate, negative interest rate and accumulation of domestic debt.
The "Financial Management and Public Debt" law no 95/ 2004 made a great change in those methods of Financing fiscal deficit in Iraq. Before 2004, the deficit was financed by issuing Treasury Bills and selling them to the Central Bank of Iraq with a prefixed interest rate. Thus, i

Different operating parameters such as the degree of bentonite activation, activated bentonite loading, and operating time was investigated on the effect of heavy metal removal efficiency. Experimental results of adsorption test show that Langmuir isotherm predicts well the experimental data and the maximum bentonite uptake of vanadium was 30 mg/g. The bentonite activated with 50 wt% H2SO4 shows a (75%) removal for both Ni and V. Results indicated that within approximately 5 hrs, the vanadium removal efficiencies were 33, 45, and 60% at vanadium loadings of 1

A current mode control at a constant switching frequency is used as a control strategy for PFC converter. The PFC converter is a single-stage singleswitch boost converter that uses a current shaping technique to reshape the non-sinusoidal input current drawn by the bulky capacitor in the conventional rectifier. This technique should provide an input current with almost free-harmonics, comply with the IEC61000-3-2 limits, and a system operates with near unity power factor. The other function of the boost converter that should be
