This research aims to study the relationship between sports anxiety and accuracy of aiming when jumping high in handball, considering that anxiety is one of the most important psychological factors affecting the skill performance of athletes, especially in precise and complex tasks. The study relied on the descriptive associative approach, where data were collected from a sample of fourth-stage students at the Faculty of physical education and sports sciences at the University of Baghdad for the academic year (2024-2025), numbering (16) students, and anxiety levels were measured using standardized scales, in addition to evaluating the accuracy of aiming when jumping high according to specific technical standards. The results showed that the average anxiety level of the players was (45.31 ± 5.86), while the average accuracy of aiming was (12.19 ± 2.93). The results also revealed a statistically significant negative correlation between sports anxiety and aiming accuracy (r = -0.58), a value that exceeds the tabular value (0.497), indicating that increased anxiety is associated with a decrease in performance accuracy. This result was explained by the fact that anxiety consumes attentional resources and distracts concentration, also increases muscle tension and affects visual–motor coordination, which impairs the ability to accurately execute the aiming skill when jumping. She recommended that psychological training programs such as relaxation exercises, mindfulness, and simulating stress situations should be integrated into the players' physical and skill preparation plans.

This study was aimed to evaluate the effect of spraying nano chitosan loaded with NPK fertilizer and nettle leaf and green tea extracts on the growth and productivity of potato for the spring and fall seasons of 2021.It was conducted at private farm in Wasit Governorate, Iraq, as a factorial experiment (5 × 5) within randomized complete block design using three replicates. The first factor included spraying with four concentrations of chitosan nanoparticles loaded with NPK fertilizer 0, 10. 15 and 20% in addition to chemical fertilization treatment, the second factor was spraying nettle leaf extract 25 and 35 gL-1 and green tea extract with 2 and 4 g.L-1, in addition to the control treatment, spraying with distilled water only.

Unconfined Compressive Strength is considered the most important parameter of rock strength properties affecting the rock failure criteria. Various research have developed rock strength for specific lithology to estimate high-accuracy value without a core. Previous analyses did not account for the formation's numerous lithologies and interbedded layers. The main aim of the present study is to select the suitable correlation to predict the UCS for hole depth of formation without separating the lithology. Furthermore, the second aim is to detect an adequate input parameter among set wireline to determine the UCS by using data of three wells along ten formations (Tanuma, Khasib, Mishrif, Rumaila, Ahmady, Maudud, Nahr Um

The adsorption ability of Iraqi initiated calcined granulated montmorillonite to adsorb Symmetrical Schiff Base Ligand 4,4’-[hydrazine-1, 2-diylidenebis (methan-1-yl-1-ylidene)) bis (2-methoxyphenol)] derived from condensation reaction of hydrazine hydrate and 4-hydroxy-3-methoxybenzaldehyde, from aqueous solutions has been investigated through columnar method.The ligand (H2L) adsorption found to be dependent on adsorbent dosage, initial concentration and contact time.All columnar experiments were carried out at three different pH values (5.5, 7and 8) using buffer solutions at flow rate of (3 drops/ min.),at room temperature (25±2)°C. The experimental isotherm data were analyzed using Langmuir, Freundlich and Temkin equations. The monol
