Study of Mechanical Properties of (Al-Cu-Mg) Alloy Matrix Composite
...Show More Authors

The present research had dealt with preparing  bars  with the length of about  (13 cm) and  adiametar  of  (1.5 cm) of composite materials with metal  matrix  represented by (Al-Cu-Mg) alloy cast enforced by (ZrO2) particles with chosen weight  percentages (1.5, 2.5 ,3.5, 5.5 %). The base  cast and the composite  materials were prepared by casting method by uses vortex  Technique inorder to  fix up (ZrO2) particles in homogeneous way on  the  base cast. In addition to  that, two main groups of composite materials were prepared depending on the particles size of (ZrO2) , respectively.                  

     The study also contained the effect of insolution heat treatment at (505 0C) and the following forming process in addition to aging process at (185 0C) during different periods for all the prepared models. Also we caried on the study of the effect of reinforcement the base cast process with zerconia particles (ZrO2) on some of its mechanical properties. The optical microscopy test should that the microstructures of the composite materials having fine grains as comparet with large grains more of the base cast.  As for hardness test & tensile test results showed an increase in hardness & tensile strength in addition to the increase in (ZrO2) that was added to reach the highest values when the weighted percentage of 3.5% and the amount of(140H.V),(570MPa) respectively. It was noted that the ductile values are reduced

continuously with the   increase of the added (ZrO2) .                                                                                      

     The effect of particle size of (ZrO2) particles on the mechanical properties, it was noted that there was a little reduction in the values of hardness and tensile strength with an increase of the particle size of (ZrO2) bat remains higher than in the base cast and the amount of(110H.V),(210MPa) respectively. While there was an increase in the ductilevalues with increasing the particle size but they still less than in the base cast.

The State of the Practical Application by Students at Department of Information and Technology and Libraries/ Institute of Administration-Al-Rusafa: A Developmental Evaluative Study
...Show More Authors

Practical application is an effective tool for preparing qualified scientific and technical cadres if applied correctly and efficiently. In addition to being the complementary part of everything that has been studied in the years of study, it is a scientific linking tool between theory and application. Here lies the importance of this research in clarifying the central and important role that practical application plays in general in raising the scientific level of the student, and the extent of the suitability of the curriculum and means of practical application and the extent and needs of the students applying at the Institute of Administration - Rusafa - Department of Information Technology and Libraries. This research attempted to answe

...Show More Authors

Objectives: The study intends to identify the sources of work-related stress that might face the nurses working at
psychiatric wards in Baghdad psychiatric hospitals and to find out a relationship between the levels of stress and
some demographic characteristics.
Methodology: A descriptive study was achieved from the 10th of December, 2013 through the 10th of March, 2014.
Non-probability purposive samples of 94 nurses who work in psychiatric wards of Baghdad psychiatric hospitals
were recruited to meet the study objectives. Psychological Stress Inventory (PSI) the Arabic version, which was
modified by Abu Al-Hussein (2010) (20), was used. Data were analyzed by using the statistical analysis program of
