The world is keeping pace with evolution in all its fields as a result of scientists' pursuit of continuous scientific and technological development. This evolution included the sports field, which had a large space in the aspect of development and for all disciplines, Therefore, it's reflected today in what we see of records and advanced achievements in sporting events and activities. The development in the field of sports was the result of scientific research (Hussein and Jawad., 2022), where the interest in the training process has become one of the most important pillars of the development of achievement (Neamah and Altay., 2020). The shooting sport has also witnessed a remarkable development due to the diversity and development of its teaching and training methods, in which the means of learning and training had to develop also in the stages of the shooting process. Thus, it became necessary to find new educational means to ensure the acceleration of shooter learning on the one hand. In addition to helping the trainee to reach the planned level, to facilitate the process of teaching the performance of the stages of the shooting process on the other hand. The development at the level requires the trainers to use applied sciences (Drwysh and Farida, 2017). Dry training for shooters is one of the appropriate educational methods for mastering all the technical, sensory, and motor elements of the shooters performance as it is an essential part of the learning and training process in shooting with air weapons without the use of ammunition. Dry training is one of the educational and training methods at the same time to master all the technical and sensory elements of the shooters' performance. This technique is not a substitute for direct training or direct throwing, it is an essential part of the air weapons training process in general and the air gun weapon in particular. That is, developing an ideal image of different positions of pistol or gun throwing and developing a mental image of the performance attitudes of the accuracy of correction. Accordingly, it is considered one of the training methods for learning the skills of shooting with air weapons, where the aids have an effective impact on the learning and training process. As well as its fundamental role in developing the skill side of the shooters. According to this modern trend, educational devices and aids are manufactured from raw materials available in the local environment at a low cost in order to develop the accuracy of correction in the air pistol for young female shooters. Accuracy is one of the main requirements in shooting (Khalid., 2019), as Researchers use many methods to find out the most important errors that occur when shooting with an air pistol. These errors included the most suitable for the shooting skill, which is the radial, constant, and variable error measures because most of the skills deal with accuracy mainly. The error measures are also adopted at present in order to be clear to the shooter and the coach in order to know the causes of the committed errors that result in poor performance. Hence the research's importance lies in developing a training program for dry training using aids to know the errors that occur at an accuracy of correction with an air gun and the extent of the shot deviation from the center of the target by means of error measures. The researchers aimed to reduce and treat performance errors and weaknesses as much as possible in order to raise the skill capabilities of the accuracy of correction with an air pistol.

In order to evaluate the effect of seed size, plant growth regulators and some chemical materials on seed vigour and seedling growth of rice (Oryza sativa L.) an experiment was conducted in 2015 at Laboratories of Agriculture and Marshes College, University of Thi-Qar. Factorial experiment in CRD was used with four replications in two factors. The first factor included three seed sizes (4.6-5.1, 5.2-5.7 and 5.8-6.3 mm). The second factor was seeds soaking treatments (KNO3 6 gl-1, CaCl2 20 gl-1, salicylic acid 20 mg l-1, cytokinin 40 mg l-1, gibberllic acid 400 mg l-1, ascorbic acid 40 mg l-1 and seeds soaked in distilled water). The results showed that the largest seed size influenced significantly and gave the higher averages of germinatio

The electronic and vibrational properties of MgxZn7-xO7 wurtzoids, were investigated, including energy gaps, bond lengths, spectral properties, such like infrared spectra and Raman. IR and Raman spectra were compared with experimental longitudinal optical modes frequency results. The theoretical results agree well with experiments and previous data. It has been found that the energy gap is increasing with the increased Mg concentration, and that the longitudinal optical position exposes a UV shift movement with an increase in the concentration.

Chlorine disinfection is a globally used method to ensure the safety of drinking water. However, it has not always been successful against viruses and, therefore, it is important to find new methods to disinfect water. Seventeen different coliphages were isolated from the treated municipal wastewater. These coliphages and MS2 were treated with different dosages of chlorine in drinking water, and a combined chlorine/ultraviolet irradiation treatment for the chlorine-resistant coliphages. Chlorine disinfection with 0.3–0.5 mg/L total chlorine (free Cl-dosage 0.12–0.21 mg/L) for 10 min achieved 2.5–5.7 Log10-reductions for 11 sensitive coliphages. The six most resistant coliphages showed no reduction with these chlorine concentra

ABSTRACT Background: According to Branemark’s protocol, the waiting period between tooth extraction and implant placement is 6–8 months; this is the late placement technique. Achieving and maintaining implant stability are prerequisites for a dental implant to be successful. Resonance Frequency Analysis (RFA) is a noninvasive diagnostic method that measures implant stability. The aim of this study was to investigate the influence of treatment protocol and implant dimensions on primary implant stability utilizing RFA. Materials and methods: This study included 63 Iraqi patients (37 male, 26 female; ranging 22-66 years). According to treatment protocol, the sample was divided into 2 groups; A (delayed) & B (immediate). Dental im

Background: Obesity increases the host’s susceptibility by modulating the immune and inflammatory systems in a manner that predisposes to inflammatory tissue destruction and leaves an individual at greater risk of periodontitis. Melatonin is a pineal secretory product involved in numerous actions, such as regulation of internal biological clocks and energy metabolism, and it functions as an antioxidant and anti-inflammatory agent. There exists a substantial amount of evidence supporting the beneficial effect of melatonin supplementation on obesity and its complications. Aim of the study: To investigate the effects of systemic melatonin intake on periodontal health status and lipid profiles in obese periodontitis patients. Subjects and met

Methotrexate (MTX) was used for treatment of malignancies and now is widely used in treatment of rheumatoid arthritis. In this research the evaluation of the effects of MTX on some liver enzymes and lipid profile was studied. Twenty four adult female mice divided into three groups (8 mice each). The first two groups were treated with MTX while the third group was used as a control. MTX was intraperitoneally given at 50 µg/ml and 75 µg/ml to the first and second groups respectively for 35 days ,whereas the control group was intraperitoneally injected with normal saline. The results showed a significant (p<0.05) increase in serum levels of glutamic oxaloacetate transaminase (GOT) , glutamic pyruric transaminase (GPT), Alkaline pho
