Maxwellian-Averaged Neutron Capture Cross-Sections and Thermonuclear Reaction Rates for 56,57,58Fe, 59Co, And 60Ni Isotopes at Astrophysical Energies
...Show More Authors
Abstract<p>Initially-produced isotopes during the course of the <italic>s</italic>-process have a significant impact on the continuity and branching network of this process. Such isotopes can undergo various neutron capture mechanisms, of which (n, <italic>γ</italic>) is important. In this research, the direct, thermal, and Maxwellian-averaged cross section (MACS), as well as the astrophysical reaction rates of the radiative neutron-capture reactions, were calculated for <sup>56,57,58</sup>Fe, <sup>59</sup>Co, and <sup>60</sup>Ni isotopes. At kinetic energies between kT = 0.037 and 482.3 keV, corresponding to astrophysical temperature in the range of 0.01 to 1GK. E1 transitions of <italic>s</italic>-wave were considered with the approximations of direct non-resonant components. The obtained MACSs and hence reaction rates were based on the data from the major measured and evaluated nuclear libraries and tables and they showed very well agreements with the most recommended database and compilations. Moreover, the effect of the direct, thermal, and negative resonance cross sections on the MACS was found to be very small and exhibit a 1/v behavior overall temperatures, with a maximum at <italic>T</italic> = 0.01GK, while the main contribution attributed to the positive resonance term, that found to dominate overall temperature range.</p>

The use of IT infrastructure and its impact on the performance of human resources in public universities: A field study at the University of Diyala
...Show More Authors

This study aims to identify the impact of using the infrastructure of the Information Technology (IT) on the performance of human resources in the public universities. This process is done by doing research in the size, quality, and efficiency of the performance, also speed of achievement and simplification of procedures. Diyala University was chosen for the diagnosis through the opinions and attitudes of its employees.  Consequently, suggestions that contribute to improve the performance of the employees and thus its overall performance are obtained. Another objective of this study is identifying the human resources which are currently used in academic institutions and educational services systems because the significant role of th

Analytical Study of Touch Areas and Preparatory Movements Leading to The Touch in Epee Fencing in The Men's Team Final at The Paris 2024 Paralympics
...Show More Authors

In sports where technical performance is crucial, quantitative analysis methods have evolved to track skill performance using modern training methods and technology. This helps trainers evaluate training methods and detect performance issues. Coaches and athletes know that preliminary movements improve attack accuracy, but the association between motions (strikes, presses, crushes) and target regions (torso, armed arm, head) has not been thoroughly investigated. Lack of studies on Paralympic fencing's targeted contact regions and ambiguity around the most common preliminary actions highlight the research problem. The study examined epee fencers' successful movement sequences in the Paris 2024 Paralympic Games' final bouts and touch success

The goal of this research is to find the effects of both the studying students groupwhich has various educational levels and the integration of the fragmented information through or during the study of history subjects for the female students of the fifth secondary literary section.
To achieve this study or case the researcher has chosen an experimental design or test by studying three groups: two are as mentioned above and the third is just ordinary team. In addition to that, there is a test after the experiment. The researcher chose on purpose female students of the literal section from two different secondary school Al Asil and Wahran both are secondary school for girls, and both are from directorate of education- Al Karkh 2nd dist

Analysis of Impoliteness Strategies Used in Putin's Speech at Annexation Ceremony
...Show More Authors

This study aims to investigate the types of impoliteness strategies used in Putin's speech at the annexation ceremony. All of Putin's speeches were intentionally delivered to cause damage to the hearers' negative and positive faces. Culpeper's (2011) classifications of impoliteness, which consist of five strategies that are the opposite of politeness, were adopted. The data were collected from the President of Russia, providing a rich source for analysis. Qualitative and quantitative analyses were employed to achieve the study objectives. Qualitative analysis allowed for a detailed examination of the impoliteness strategies employed, while quantitative analysis provided a broader understanding of their frequency and distribution. Putin most
