The article presents the results of studying the chemical-mineralogical and physical-mechanical characteristics of Angren secondary kaolin and kaolinite clay and their suitability for obtaining aluminosilicate proppants. It was found that the melting point of Angren secondary kaolin is 1540 ° C and the compressive strength in the fired at a temperature of 1400 ℃ reaches up to 105 MPa, and for kaolinite clay these indicators showed 1505 ℃ and 109 MPa, respectively. The obtained indicators suggest that these clay materials can be used as the main component for obtaining aluminosilicate proppants.

The performance of health care systems is a critical factor influencing public health outcomes, and mortality indices serve as key indicators in evaluating this performance. This study aims to conduct an international comparison of health care systems by analyzing mortality indices across different countries. Utilizing a comprehensive dataset that includes various mortality rates—such as infant mortality, life expectancy, and age-adjusted mortality—the study provides a comparative assessment of health care effectiveness and system efficiency.

We employed statistical methods to analyze mortality data from multiple countries, examining correlations between mortality indices and health care system attributes such as access to care, quality of services, and health expenditures. The analysis reveals significant variations in health care system performance, highlighting differences in mortality outcomes and identifying best practices among high-performing systems.

Key findings include variations in mortality rates attributable to differences in health care policies, resource allocation, and preventive care measures. Countries with higher investment in health care infrastructure and preventive services generally demonstrated better mortality outcomes. The study also identifies areas where improvements can be made, particularly in systems with less favorable mortality indices. This comparative analysis provides valuable insights for policymakers and health care administrators seeking to enhance system performance and improve health outcomes. By understanding the factors that contribute to successful health care systems, countries can adopt effective strategies to reduce mortality rates and achieve better overall public health.

Laser-plasma interactions are fundamental to a range of applications, from inertial confinement fusion to advanced material processing. Understanding the linear absorption mechanisms within these interactions is crucial for optimizing performance and predicting outcomes. This study investigates the linear absorption processes that occur when intense laser fields interact with plasmas. Through a combination of theoretical modeling and experimental analysis, we explore how factors such as laser intensity, plasma density, and wavelength influence the absorption characteristics. Our findings reveal key insights into the absorption efficiency and its dependence on plasma parameters, providing a deeper understanding of energy deposition and plasma behavior. The results have significant implications for enhancing the precision of laser-driven systems and improving the efficacy of plasma-based technologies.
