Background: CT (computed tomography) is one of the first noninvasive imaging techniques in diagnosis of intra-axial posterior fossa tumors because it can accurately demonstrate, localize and characterize brain tumors, and can provide important information about the anatomic location, size, shape of the lesions and their mass effect on adjacent structures.
Objectives: To evaluate multi detectors CT characteristics of intra axial posterior fossa tumors and correlation of the CT characteristics of intra- axial posterior fossa tumors with the histopathological findings.
Patients & Methods: This is a cross sectional study including 26 patients with intra-axial posterior fossa tumors,15 males &11 females ,three cases were excluded from the study because no definite histological diagnosis was done so the final included number was 23 cases .The cases were referred from the Department of Neurosurgery in Ghazi Al-Hariri specialized surgical hospital in Medical city complex at the period between January 2012 to January 2013.
Results: The most common intra- axial posterior fossa tumors were astrocytoma, and medulloblastoma (26.1%) for both equally. These tumors are more common in pediatric age group (60.9%) than adult (39.1%). Medulloblastoma was the most common childhood tumors. Hemangioblastoma and metastasis were the most common adulthood tumors. The gender distribution of the total number of patients showed male predominance by a factor 1.5, (60.9%) were males, and (39.1%) were females.
CT scan was sensitive in detection of tumors but it was not specific to give the definite histopathalogical tumors type.
Conclusion: Medulloblastoma and astrocytoma were the most common intra axial posterior fossa tumos. The gender distribution showed male predominance. CT scan was sensitive in detection of tumors but it was not specific to give the definite histopathalogical tumors type. The confidence interval of CT in diagnosis of histopathlogical types is 65.2 % but it is still useful in the detection, localization and characterization of tumors.
Abstract The aim of this study is to identify the role played by the university in reinforcing the culture of voluntary work in college students and sequencing these roles according to their priority. To achieve this aim, the researcher used the descriptive approach. After being informed of the literature background and of the previous studies related to the core aim of this recent study, the researcher has built up a questionnaire of (20) items investigating the role of university in reinforcing the culture of voluntary work in the college students. The standardized features of the questionnaire have been checked for the purpose of the questionnaire validity (virtual and constructive validity) and stability (reconstruction and Cronbach's A

This is one of the goals of 21 Century announced during universal summit conference in 2000. The goals are : teaching children, reducing the average of the dead, in addition to the main goal which is reducing the poor level in 2015.
The increasing number of countries that adopt democratic policies, economic freedom and openness lead to heighten and develop the role of women in different ways. As a result, many feminism journals have appeared. Since journals help people to make decisions about public issues as well as acquiring new knowledge, it stimulates women to make decisions.
Feminism journalism takes a new trend. It has become specia
Fluid-structure interaction method is performed to predict the dynamic characteristics of axial fan system. A fluid-structure interface physical environment method (monolithic method) is used to couple the fluid flow solver with the structural solver. The integration of the three-dimensional Navier-Stokes equations is performed in the time Doman, simultaneously to the integration of the three dimensional structural model. The aerodynamic loads are transfer from the flow to structure and the coupling step is repeated within each time step, until the flow solution and the structural solution have converged to yield a coupled solution of the aeroelastic set of equations. Finite element method is applied to solve numerically

Patients and methods: We took 20 patients from the retrospecture data before the use of Navigator in our country compared with the 20 patients managed after the use of navigator in our hospital (specialized surgical hospital) in the neuro-surgical. Unit since 2002 till now. From 1/8/2002 till 31/12/2007 the study included the type of tumor & surgery & the result of surgery & time & complications ((morbidity & mortality)).
Results: There was a significant increase of the safety of surgery by using the navigator

Federal Board of supreme audit Office is one of the most important regulators in Iraq. The problem of the research was the fundamental question of the extent to which the Federal Financial Supervisory Office was committed to implementing and exercising environmental control over the audited ones. The refore, the research was based on the main objective of questioning the role of the Federal Financial Supervisory Office in the exercise of environmental control and the compliance of those under its control, by identifying the antosai standards for environmental control, particularly the stand
