The article discusses the principles of assessing the magnitude of irrigation impact on the territory of South-Western Uzbekistan, and methods for compiling engineering-geological maps. Methodological foundations for medium-scale engineering-geological mapping have been developed based on formational and lithological-genetic analysis of the structure of the territory, taking into account epigenesis and hypergenesis. Certain questions about the principles and methods of engineering geological mapping of both irrigated and rain-fed zones are considered, the composition and content of various spe

In this paper determined the Lie’s symmetries of wave equation on torus. Symmetry algebras are found by using Lie’s classical method. We use different symmetries to obtain similarity reductions of wave equation by exploiting these symmetries, we perform similarity transformations, a powerful reduction for obtaining two new solutions of wave equation on torus. We investigated the new solutions of wave equation on a specific geometry surface torus.

The rapid evolution of digital technologies has profoundly impacted the healthcare sector, making digital competencies essential for health informatics professionals. As healthcare increasingly integrates digital tools, the demand for professionals proficient in these skills has grown significantly. This study explores the digital competencies of final-semester students in the Health Informatics program at the University of Hail. The aim of this study is to assess the digital competencies of final-semester health informatics students, identify gaps in the current curriculum, and provide recomm

Regenerative braking in the braking system adds value to the total efficiency of the vehicle, especially an electric car. Driving style also determines the effectiveness of the regenerative braking system. In panic braking conditions, the antilock braking system (ABS) provides stability in the braking process. This study varies the ABS piston frequency from 10 to 50 Hz to obtain an effective braking process and high-power output. The flywheel was installed as a medium to harvest energy during the braking process. The results obtained ABS piston frequency of 10 Hz provides the highest braking s

The study seeks to demonstrate the influence of transactional, transformational, and laissez- faire leadership styles on personnel performance. The study was based on a quantitative, cross-sectional approach, with explanatory-correlational scope and non-experimental design. A sample of 177 individuals belonging to the Third Cavalry Brigade of Tacna (Peru) was chosen. The obtained results were evaluated using structural equations applying partial least squares. It was evidenced that there is a 79% influence of transformational leadership on performance, a 32% influence of transactional leadersh
