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.

Performance Evaluation of Composite CNT/PE-Modified Asphalt Concrete at Binder, Mixture, and Pavement Levels
...Show More Authors

Advancing the multi-scale performance of asphalt pavements requires innovative binder modifications that address limitations in rutting resistance, fatigue resistance, and durability across the binder, mixture, and structural levels. This study evaluates the performance of asphalt cement, mixtures, and pavement systems modified with a combination of polyethylene (PE) and carbon nanotubes (CNTs). The binder was modified using 4% PE and varying CNT contents (0.5%, 1%, 1.5%, and 2% by weight of the modified binder). Binder performance was assessed through conventional and rheological tests, including penetration, softening point, viscosity, performance grade (PG) evaluation, and master curve analysis. Mixture-level performance was eval

Electrosorption of cadmium ions from the aqueous solution by a MnO2/carbon fiber composite electrode
...Show More Authors

The nanostructured MnO2 /carbon fiber (CF) composite electrode was prepared using the anodic electrodeposition process. The crystal structure and morphology of MnO2 particles were determined with X-ray diffraction and field-emission scanning electron microscopy. The electrosorptive properties of the prepared electrode were investigated in the removal of cadmium ions from aqueous solution, and the effect of pH, cell voltage, and ionic strength was optimized and modeled using the response surface methodology combined with Box–Behnken design. The results confirm that the optimum conditions to remove Cd(II) ions were: pH of 6.03, a voltage of 2.77 V, and NaCl concentration of 3 g/L. The experimental results showed a good fit for the Freundli

The conversational imperative in Al Qiyam Al Fatimy speech
...Show More Authors

This study falls within the core of the deliberative theory, as this research seeks to highlight the concept of dialogical imputation that is present in all the discourses received by the recipient, and that this is not limited to dialogues, and that is why it is called (deliberative imperative). This is in agreement with the deliberative and functional approach that sees literary discourse as a dialogical and fulfilling necessity, due to its attachment to artistic connotations and submerged meanings in the saying. The allotted obligation and its impact on determining the purposes: The specific implication represented an important axis of pragmatic research, and a major concern in the work of discourse analysis. Because of its great importa

The causes of fear in the world An original Quranic study
...Show More Authors

The subject of fear is one of the most important tasks that one should seek to find out the reasons behind it, and push it up with all its sound mental concepts.
     The main reason for the lack of security and fear and disturbance in the world is to commit the legitimate violations that God warned us in his Holy Book as well as in the Sunnah of His Prophet (peace be upon him).
    The talk about the causes of fear in the Koran is not limited to the word (fear) Fakk but came in different and varied methods such as (horror) and (awe) and (shares) and (narrow).
