In this study, generation of elliptical gears with different teeth profiles of crowned involute, double circular arc (DCA), and combined (crowned involute with DCA) has been developed. The resulting mathematical equations have been computerized and feed to CNC end mill machine to manufacture elliptical gear models with different profiles. These models are investigated in plane polariscope to show the resulting stresses under certain load. Comparison of photo-elastic stress results shows that combined elliptical gears with DCA side as a loaded side have a minimum resulting contact stress with a reduction percentage of 40% compare with contact stresses in counterpart elliptical gear of involute profile (which is commonly u

This study's objective is to assess how well UV spectrophotometry can be used in conjunction with multivariate calibration based on partial least squares (PLS) regression for concurrent quantitative analysis of antibacterial mixture (Levofloxacin (LIV), Metronidazole (MET), Rifampicin (RIF) and Sulfamethoxazole (SUL)) in their artificial mixtures and pharmaceutical formulations. The experimental calibration and validation matrixes were created using 42 and 39 samples, respectively. The concentration range taken into account was 0-17 μg/mL for all components. The calibration standards' absorbance measurements were made between 210 and 350 nm, with intervals of 0.2 nm. The associated parameters were examined in order to develop the optimal c

This study presents determination of the paleostress magnitudes and orientation of Bekhme Structure in Shaqlawa area northeastern Iraq. Paleostress Analysis of slip-fault measurements is performed using Right dihedral, Lisle diagram and Mohr Circles methods. Depending on Mohr Circles, Bott law and vertical thickness, the magnitudes of the paleostress at the time of the tectonic activity were determined. Firstly, Georient Software was used to estimate the orientation of the paleostresses (σ1, σ2 and σ3). Secondly, using the rupture –friction law, taking into account depth of the overburden and the vertical stress (σv) was calculated to determine the magnitude of the paleostresses (σ1=4500 bars, σ2=1

ABSTRACT

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 1980_s. 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

  That it is essential to be for us to recognize is that the phenomenon of poverty are addressed most of the doors of Arab countries in general and Iraq in particular, with the contrast between Qatar and another, and that the deteriorating situation of developing countries it is clear that poor people are victims of exploitation and inequality.
  That dealing with the phenomenon of poverty should be more present in mind, especially since the Arab world that enters the era of so-called globalization, as more people poor, and the increase of the utilization of materials Arab interests abroad under the competition is unequal and the impoverishment of deliberate environmental and resource Arab
