The study of history has begun to become increasingly important for those interested in the field of education in general, and physical education and sports sciences in particular. It is a recent study of the past and relying on it. Therefore, studying the history of sports for people with disabilities and their development is of great importance, as it is one of the means to measure the extent of development of societies and their culture in this field. Weightlifting is a sport for people with motor disabilities, and the way to play is for the contestant to lie on the bench (ping bar) and most often the legs are tied to the bench to ensure that the hip and legs do not contribute to the lifting process with the arms, when the player grabs the iron bar (bar) and pulls it to the chest and its stability on it, then push it up without the inclination of the barbell, and the attempt is considered a failure if the player is unable to push the barbell up, or the inclination of the barbell occurs during the push, or raise one side without the other. The study aimed to track the historical process of the participation of weightlifting players with a motor disability weighing 49 kg in the Iraq Clubs Championship for the period (2019-2022), and to identify the most important achievements for weightlifters with motor disabilities, and to analyze and criticize the most important reasons for the level development of weightlifting players from People with motor disabilities, and the two researchers relied in collecting data, information and results on the historical and analytical approach based on a number of references related to the problem of the study, as well as the documents of the Iraqi Paralympic Federation for weightlifting, and included the study community and appointed by weightlifting club players and participants in local tournaments for the period under study. In light of the obtained results, the two researchers came out with a number of conclusions: The participation of weightlifters with motor disabilities was at a good level, as there is an increase in the number of players participating in the tournament, and there is a noticeable increase in the level of lifts recorded for weightlifters with disabilities. Mobility handicap, first place holders. While the most important recommendations are: It is important to follow the historical course of the sports of people with motor disabilities by codifying and objective analysis of the participation and achievement of the players, because these groups represent constructive energies that reflect the development and advancement of Iraqi society, and the need to highlight the sports of people with disabilities by officials and specialists in all state institutions to provide all means of care and attention for them, as well as sports support by preparing all sports supplies and equipment that push them to achieve advanced achievement
Tin Selenide (SnSe) Nano crystalline thin films of thickness 400±20 nm were deposited on glass substrate by thermal evaporation technique at R.T under a vacuum of ∼ 2 × 10− 5 mbar to study the effect of annealing temperatures (as-deposited, 100, 150 and 200) °C on its structural, surface morphology and optical properties. The films structure was characterized using X-ray diffraction (XRD) which showed that all the films have polycrystalline in nature and orthorhombic structure, with the preferred orientation along the (111) plane. These films was synthesized of very fine crystallites size of (14.8-24.5) nm, the effect of annealing temperatures on the cell parameters, crystallite size and dislocation density were observed.
... Show MoreThe university course timetable problem (UCTP) is typically a combinatorial optimization problem. Manually achieving a useful timetable requires many days of effort, and the results are still unsatisfactory. unsatisfactory. Various states of art methods (heuristic, meta-heuristic) are used to satisfactorily solve UCTP. However, these approaches typically represent the instance-specific solutions. The hyper-heuristic framework adequately addresses this complex problem. This research proposed Particle Swarm Optimizer-based Hyper Heuristic (HH PSO) to solve UCTP efficiently. PSO is used as a higher-level method that selects low-level heuristics (LLH) sequence which further generates an optimal solution. The proposed a

There for; encourage, adapting,and imitating of friends and group consider as the main reasons behind starting of smoking among youngsters. Smoking habits in the family were found tobe acause of smoking pressure among adolescentas peer pressure. Smoking habit may be started before 18 years of age in most adult smokers.
Objectives: To study the effect of peer pressure and family smoking habiton the prevalence of smoking among secondary school students.

... Show MoreRemoving Congo red (CR) is critical in wastewater treatment. We introduce a combination of electrocoagulation (EC) and electro-oxidation (EO) to address the elimination of CR. We also discuss the deposition of triple oxides (Cu–Mn–Ni) simultaneously on both anodic and cathodic graphite electrodes at constant current density. These electrodes efficiently worked as anodes in the EC-EO system. The EC-CO combination eliminated around 98 % of the CR dye and about 95 % of the Chemical Oxygen demand (COD), and similar results were obtained with the absence of NaCl. Thus, EC-EO is a promising technique to remove CR in an environmentally friendly pathway.
