The research aimed to identify and build two specialized scales for cognitive load and mental stress and to identify the level of each of them among 110-meter steeplechase runners among youth, and to prepare a psychological counseling approach to reduce the level of cognitive load and mental stress among 110-meter steeplechase runners among youth, so that the two research hypotheses are that there are differences. There are statistically significant differences between the results of the pre- and post-tests of the experimental group in measuring cognitive load. There are statistically significant differences between the results of the pre- and post-tests of the experimental group in measuring mental stress. The experimental method was adopted by designing a single experimental group with a pre- and post-test. On a sample of (8) runners who ran a distance of (100) meters from the youth category, was chosen intentionally after wiping the scales to represent (42.105%) of their society represented by the two times that ran (110) meters of contraindications from the youth number of (19) runners in The Sports Army Club for the Sports Decree (2023/2024), as was chosen from a similar society from other Baghdad clubs for the same event (5) runners for the exploratory experience, and (105) runners -up for the building sample, and two specialties were built for this category of runners and in a manner that is appropriate for the specificity of the current research By adopting several steps, and then preparing the psychological counseling approach based on the reduction of both the two phenomena, which are speaking to the adoption of the diagnostic measurement, and it was applied with the research experience that started with the application of the two phenomena -speaking phenomena in the tribal tests on Sunday (3/3/2024), and then applying the program The psychological counseling of the ran (110) meters of contraindications for the period from (4/3/2024) until (10/4/2024), and for Monday of each week, and the experimentation of experimenting with dimensional tests on Thursday (11/4/2024), To be processed by data (SPSS) So that the conclusions and applications are that the two measures of cognitive-cognitive play and mental stress are suitable for young (100) meter steeplechase runners, they are suitable for what they were prepared for to measure these two phenomena, and each of them has the scientific conditions for the foundations and parameters for accepting the measures in sports psychology, and the practical applications of the psychological counseling approach based on To reduce the level of cognitive load and mental stress, it is suitable for young 100-meter steeplechase runners. It is necessary to pay attention to diagnostic psychological measurement and its applications to young 100-meter steeplechase runners to monitor their psychological state and avoid or reduce psychological problems before their level increases. It is necessary to take into account The specificity of the training and competitive environment, hostile (100) meters, obstacles and concepts of specialized sports psychology in preparing the appropriate psychological counseling curriculum for this category of youth.
The specific activity of 29 soil samples collected from Fuel
Fabrication Facility FFF at AL-Tuwaitha site, 20 km south of
Baghdad were determined using HPGe detector in a low background
configuration, it's relative efficiency of 40%, and resolution of 2keV
for the 1332 keV gamma ray emission of 60Co. The range of activity
concentrations of 226Ra, 232Th and 40K were between (12.56-31.96),
(10.2-18.4) and (47.47-402.1) Bq/kg respectively. In order to assess
any radiological hazard to human health, the absorbed gamma dose
rate D in air at 1m above the ground surface was calculated in the
range (18.87 to 36.46) nGy/h; the outdoor annual effective dose
equivalent AEDE was evaluated to vary from 0.0039 to 0.0076
Sewage sludge samples were collected from Al-rasafa and Al-karkh refinement stations which represent the main stations of Baghdad city. Samples were collected from all treatment stages: before, after, and during refinement processes. The High Purity Germanium Coaxial Detector system with energy resolution 1.8 keV for energy line 1333 keV of Co – 60 radioactive sources was used to measure radioactivity from both natural and artificial sources. GENIE – 2000 analysis the results statistically and qualitatively. The results showed that all sewage sludge samples exhibited natural radioactive level and sometimes less than the international regular standards, but Al–Karkh station showed increment in radioactive levels than Al– Rasa

This paper addresses the issue of cleaning the surface of the samples with different spot sizes (50, 100 and 200) (industrial ytterbium fiber laser) to prepared it to be welded. Angular laser cleaning with incident angles (5, 10, 15, 20, 25, 30) ° with different powers (3, 5, 7, 10) W and hatch distance 0.001 was use for implemented.
The present investigation aims to study the effect of heat treatment by quenching in different quenching media (salt water, water and oil) following by tempering on wear resistance of EN25 steel. EN25 steel is an alloy of medium carbon low alloy steel which is used for many applications requiring high tensile strength and wear resistance such as connecting rods, adapters and in power sectors extensively. The specimens are machined to 20 mm in length and 10 mm in diameter. This study is done by two stages: The first stage is done by austenitizing EN25 steel to 850 for 1 hr by quenching the specimens in three different quenching media and then tempered at 300 in air. While the second stage is performed by wear
... Show MoreNormal concrete is weak against tensile strength, has low ductility, and also insignificant resistance to cracking. The addition of diverse types of fibers at specific proportions can enhance the mechanical properties as well as the durability of concrete. Discrete fiber commonly used, has many disadvantages such as balling the fiber, randomly distribution, and limitation of the Vf ratio used. Based on this vision, a new technic was discovered enhancing concrete by textile-fiber to avoid all the problems mentioned above. The main idea of this paper is the investigation of the mechanical properties of SCC, and SCM that cast with 3D AR-glass fabric having two different thicknesses (6, 10 mm), and different layers (1,2 laye
... Show MoreIn this study the simple pullout concrete cylinder specimen reinforced by a single steel bar was analyzed for bond-slip behavior. Three-dimension nonlinear finite element model using ANSYS program was employed to study the behavior of bond between concrete and plain steel reinforcement. The ANSYS model includes eight-noded isoperimetric brick element (SOLID65) to model the concrete cylinder while the steel reinforcing bar was modeled as a truss member (LINK8). Interface element (CONTAC52) was used in this analysis to model the bond between concrete and steel bar. Material nonlinearity due to cracking and/or crushing of concrete, and yielding of the steel reinforcing bar were taken into consideration during the analysis. The accuracy of t
