The Effect of Shear on the Properties of Rigid PVC
...Show More Authors

The rheological and fusion behavior of polyvinyl chloride (PVC) compounds plays a dominant role in
the processing operations and in the development of physical properties in the processed material. A
comprehensive study was made in this work to evaluate the effect of shear and thermal history on stability, mechanical and rheological properties of rigid PVC compounds. Different samples of Rigid Poly vinyl chloride including dry blend powder, granules, and bottles molded from both were examined. A study was also made on recycled RPVC where 25% of reclaimed material was continuously blended with fresh dry blend and processed for 15 cycles. Results showed that compaction of the PVC material took place in the brabender plastograph at constant temperature and shear stress. Correlations were given to explain results concerning residual stability and rheological behavior. Furthermore, it was seen that elongation and tensile impact are dependent on shear history.

The Effect of Clare's Plan on Female Students' Achievement in the History Subject in the Institute of Teachers' Preparation
...Show More Authors

Teaching through the system of personal learning, known as (Clare's plan) is amongst the most prominent plans which depend on self-education, as it received worldwide recognition. The plan lets the learner achieve learning by depending on himself after being familiar with the educational goals given to him, then he starts to solve the exercises and the drills accompanying the unit. After that, he checks his achievement by answering the self-evaluation tests. This method offers more opportunities for personal interaction than do the traditional systems, and individual leaning is a methodical expression aims at taking care of the learner and making him the locus of the processes of teaching and learning.

A careful study of the effect of the infectious diseases and refuge on the dynamical behavior of prey-scavenger modeling
...Show More Authors

In this paper, the dynamics of scavenger species predation of both susceptible and infected prey at different rates with prey refuge is mathematically proposed and studied. It is supposed that the disease was spread by direct contact between susceptible prey with infected prey described by Holling type-II infection function. The existence, uniqueness, and boundedness of the solution are investigated. The stability constraints of all equilibrium points are determined. In addition to establishing some sufficient conditions for global stability of them by using suitable Lyapunov functions. Finally, these theoretical results are shown and verified with numerical simulations.

The Effect of The LEAD Strategy on Teamwork Skills Among Second-Year Middle School Students
...Show More Authors

The current research aims to investigate the impact of the LEAD strategy on teamwork skills among second-year intermediate school students in government day schools. Umm Al-Mu'minin School, affiliated with the First Education Directorate of Al-Koura/Qom Abi Urayb, was intentionally selected as the research site for the academic year (2026- 2025). The researcher selected one of two classes as the experimental group, which studies according to the LEAD strategy, and the other as the control group, which studies according to the traditional method. The two research groups were compared in a number of variables, including (chronological age in months, intelligence test, prior knowledge, and a teamwork skills scale). The results showed that the

The Effect of Adding High-Density Polyethylene Polymer on the Engineering Characteristics for Sandy Soil
...Show More Authors

The loose sand is subject to large settlement when it is exposed to high stresses. This settlement is due to the nature of the high drainage of sand, which displays foundations and constructions to a large danger. The densification of loose sandy soils is required to provide sufficient bearing capacity for the structures. Thus soil stabilization is used to avoid failure in the facilities. Traditional methods of stabilized sandy soil such as fly ash, bituminous, and cement often require an extended curing period. The use of polymers to stabilize sandy soils is more extensive nowadays because it does not require a long curing time in addition to being chemically stable. In this study, the effect of adding different percent
