In the article, the authors highlighted the process of balloon angioplasty, i.e. stenting, performed in patients with coronary heart disease.

OPTIMIZATION OF EPITAXIAL SILICON P-N JUNCTIONS TO IMPROVE THERMAL ENERGY CONVERSION EFFICIENCY

F. Arziqulov, Sh. Kuchkanov — Fri, 11 Oct 2024 00:00:00 +0000

Epitaxial silicon p-n junctions are attracting attention for their potential applications in thermal energy conversion technologies due to their manufacturing efficiency and scalability. This paper explores the optimization of epitaxial silicon p-n junctions to improve thermal energy conversion efficiency, focusing on material properties, device structure, and fabrication techniques. We analyze different doping profiles, the role of interface quality, and thermal transport mechanisms in silicon-based p-n junctions. In addition, this study discusses challenges and opportunities in improving thermoelectric efficiency through design and manufacturing process improvements. The findings show that optimization of junction interfaces and careful control of doping concentrations can significantly improve energy conversion efficiency in silicon-based thermoelectric devices.

THE ARAB GULF STATES IN BRITISH FOREIGN POLICY

Xusan Mirzabekov — Mon, 14 Oct 2024 00:00:00 +0000

This article analyzes the role of the Arab Gulf States in British foreign policy. Historically established relations between Great Britain and the Gulf States significantly impact the political, economic and military aspects of the interaction between these regions. The article examines the key stages and directions of British policy in the region, from the colonial period to the present day, focusing on the strategic interests of Great Britain, including security issues, energy resources and trade. It also analyzes the factors that make the Persian Gulf region attractive to Western countries, especially Great Britain. The region has long attracted attention due to its rich hydrocarbon reserves and strategic geographical location. Britain's geopolitical and geoeconomic interests in the Persian Gulf play a key role in its policy in the Middle East. It is important to note that many countries in the region were previously part of the British Empire. After losing control in the mid-20th century, Great Britain was forced to reconsider its relations with the Gulf States. The UK's perception of the Persian Gulf as a strategically important part of the Middle East has prompted it to develop a unified geopolitical strategy for the entire region. Although the United States plays a leading role in the region, the UK acts within its national interests, seeking to maintain its influence on the world stage. The Gulf states have demonstrated a tendency to strengthen cooperation with Western countries, offering unique opportunities to strengthen their positions in the Middle East. In this context, the UK and the US have developed a consistent strategy to strengthen their influence in the region.
