Background: Odontogenisis is a complex process controlled by dynamic and reciprocal interactions that regulated by various molecules. Thymosin β4 is a small bioactive peptide with wide spectrum biological effects on much cell types. The present study was designed to highlight the effect of synthetic exogenous Tβ4 on developing dental tissue of the upper central teeth of rats, by histological examination and immunohistochemical evaluation of TGFβ1. Materials and method: Thirty six Albino Wister pregnant rat 18control group received intraperitoneal injection of normal saline and the others are experimental group received 50µg/300µl of Tβ4 injection. The animals were sacrificed at periods 16th and 18th day I.U.L and one day p

An experiment was conducted to study how SAE 50 engine oil contaminated with diesel fuel affects engine performance. The engine oil was contaminated with diesel fuel at concentrations of 0%, 1%, and 3%. The following performance characteristics were studied: brake-specific fuel consumption, brake thermal efficiency, friction power, and exhaust gas temperature. Each treatment was tested three times. The three treatments (0%, 1%, and 3%) were analyzed statistically with a one-way ANOVA model at the 5% probability level to determine if the three treatments produced significant differences in engine performance. The statistical results showed that there were significant differences in engine performance metrics among the three treatments. The 3

  In this research study, I tried to trace the epic effect to learn how it was understood and how it was used. Following the descriptive and analytical approach in the research, the first chapter dealt with a presentation of the methodological framework of the problem, the goal, the limits of the research, the importance and the need for it and the definition of terms, as well as the theoretical framework which consisted of two topics, including the impact of the epic theater on the world theater and the second the effect of the epic theater on the Arab theater, This came by tracing the epic impact on the world stage of the Greeks, the Middle Ages, the Renaissance, and the Arab theater of the twentieth century.
As for the second

Today, the role of cloud computing in our day-to-day lives is very prominent. The cloud computing paradigm makes it possible to provide demand-based resources. Cloud computing has changed the way that organizations manage resources due to their robustness, low cost, and pervasive nature. Data security is usually realized using different methods such as encryption. However, the privacy of data is another important challenge that should be considered when transporting, storing, and analyzing data in the public cloud. In this paper, a new method is proposed to track malicious users who use their private key to decrypt data in a system, share it with others and cause system information leakage. Security policies are also considered to be int

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
