Many studies have found effective oral influenza virus inhibitors based on an aryl benzoyl hydrazide scaffold and antiviral. This study aims to prepare a new series of derivatives containing succinohydrazide as a precursor. In the first step, after synthesis of their precursor, it has been prepared di benzoyl succinohydrazide using a two-step process that involved reacting (o,m,p)-chloro benzoic acid with thionyl chloride to obtain freshly prepared substituted benzoyl chloride derivatives that were then reacted with succinohydrazide, or by a second method, directly reacting substituted benzoyl chloride with succinohydrazide to give benzoylsuccinohydrazide derivatives. After that, different derivatives were prepared involving the

This study presents a Particle Swarm Optimization (PSO)-based scheme for optimal targeted load shedding and contingency severity assessment in the electric power grid (EPG). The IEEE 14 EPG was used as a testbed. The study identified critical branches and quantitatively evaluated the operational performance of an EPG under base case, outage without and with targeted load shedding schemes, utilizing convergence characteristics, voltage magnitudes and angles, and branch load flows as diagnostic metrics. The base case demonstrated excellent numerical stability, with convergence achieved in fewer than 5 iterations, and all bus voltages maintained within the IEEE standard range. A critical outage scenario caused severe diffic

Scabies mites penetrate the stratum corneum epidermis of the skin at the onset of infection (2, 16). The current study involved the collection of blood samples from a patient group infected with scabies disease, comprising sixty individuals, and a control group of sixty individuals who were in good health. The tests showed that there were no statistically significant differences between the scabies patients and the control group for Hb (12.86± 0.31, 12.88± 0.20), PCV (34.40±0.94, 40.35±0.59), and platelets (244.80±9.58, 237.23±8.97), Respectively.

By applying the Fuchs-Sondheier and Mayadas Shatzkces models, the study establishes a linear relationship between thickness and grain boundary scattering. The M.S. model is crucial in calculating the size impact, accounting for all types of scattering affecting grain boundaries. On the other hand, the F.S. model focuses on explaining conduction electron scattering on material surfaces, particularly on tiny grains. The study's equation, derived from these two models, considers surface scattering and metal resistance to determine an experimental thickness that depends on metal resistivity. The Boltzmann Equation can be ut

Henrik Ibsen is considered one of the greatest writers on society and its problems in the modern era, as his works deal with society in all its forms in a realistic way, in which he presents the motives and consequences of social problems and their impact on society to study these problems through them to and propose solutions through theatre. Most of his writings were very serious about addressing these social issues. The method of collecting information in the study came through reviewing a group of sources related to realistic theater and social theory, then reading the plays covered in a critical and analytical reading.
