The research included the introduction to the research and its importance as knee joint is an important joint in the human body that is prone to injury. One such injury is knee roughness injury that occurs as a result of the stress of the knee joint and age. The importance of examining the need for the use of rehabilitation exercises, especially in the watercourse system, is highlighted by the fact that the aquatic environment is one of the most important factors helping to alleviate pain and rehabilitate the knee joint and thereby improve the mobility of those with knee roughness. The problem of research is that rehabilitation exercises have been developed in the watercourse system on the basis of scientific bases with a repetitive and systematic persistence in improving the motor potentials of patients with knee roughness, knowing the extent to which the rehabilitation of the watercourse system physically affects each infected person and identifying the impact of rehabilitation exercises on those with knee roughness. There are statistically significant differences between tribal and remote test results in some of the motor abilities of former footballers aged 40-45. The objectives of preparing qualifying exercises in the watercourse for knee manhandles were for former football players aged 40-45 years. Recognize the impact of hydromassage rehabilitation exercises on some knee-rough mobility of former football players aged 40-45 years. Findings were: Qualifying exercises used by members of the research sample were positively affected in the motor range of the knee joint and in all directions. The qualifying exercises used by members of the research sample were positively affected by the motor balance of the knee joint. The following rehabilitation exercises used by the members of the research sample were positively affected by the agility of the joint - as well as the development of improved motor range balance and agility as a result of the use of rehabilitation exercises with the aquatic running system prepared in the rehabilitation curriculum, effectively affected the alleviation of the pain resulting from the injury. Recommendations: Use of the rehabilitation programme prepared by the researcher for knee manhandles in treatment centres: change of the environment and use of the aquatic environment as a psychological factor contributing to the broken boredom of the infected in addition to its effective role in treatment. Watercourse exercises and intra-water resistance are important in developing and improving the mobility of those with knee rough knee. and conducting research similar to different samples. Finally the use of a hydropower treats those with knee roughness.
An experimental study was carried out to improve the surface roughness quality of the stainless steel 420 using magnetic abrasive finishing method (MAF). Four independent operation parameters were studied (working gap, coil current, feed rate, and table stroke), and their effects on the MAF process were introduced. A rotating coil electromagnet was designed and implemented to use with plane surfaces. The magnetic abrasive powder used was formed from 33%Fe and 67% Quartz of (250µm mesh size). The lubricant type SAE 20W was used as a binder for the powder contents. Taguchi method was used for designing the experiments and the optimal values of the selected parameters were found. An empirical equation representing the r

This change can help in controlling erosions and sedimentations along the mainstream of the channel. Roughness elements can be large stone or concrete blocks placed at the channel's bed to impose more resistance in the bed. The geometry of the roughness elements, numbers used, and configuration are parameters that can affect the flow's hydraulic characteristics. In this paper, velocity distribution along the flume was theoretically investigated using a series of tests of T-shape roughness elements, fixed height, arranged in three different configurations, differ in the number of lines of roughness element

Electro-chemical Machining is significant process to remove metal with using anodic dissolution. Electro-chemical machining use to removed metal workpiece from (7025) aluminum alloy using Potassium chloride (KCl) solution .The tool used was made from copper. In this present the optimize processes input parameter use are( current, gap and electrolyte concentration) and surface roughness (Ra) as output .The experiments on electro-chemical machining with use current (30, 50, 70)A, gap (1.00, 1.25, 1.50) mm and electrolyte concentration (100, 200, 300) (g/L). The method (ANOVA) was used to limited the large influence factors affected on surface roughness and found the current was the large influence f

There is no statistically significant difference at the significance level (0.05) between the average differences in the posttest scores of the experimental group taught according to Daniel's model and the control group taught according to the traditional method in the measure of critical thinking. 2. There is no statistically significant difference at the significance level (0.05) between the average differences in the preand post-tests scores of the experimental group taught according to Daniel's model in the measure of critical thinking.

Cinnamon is a herbal substance, which has many applications in medicine. AIM: The aim of the study was to study the effect of cinnamon on patients with chronic pelvic pain syndrome. METHODS: Sixty patients with documented CP/CPPS randomized into two groups during 2018 and 2019 in Baghdad. The first group received 60 capsules each contained 1 g of cinnamon. The other group received 60 capsules each contained 1 g of sugar powder (placebo). All the patients instructed to take one capsule twice daily for 1 month. National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) was reported for bot
