ENHANCING THE MECHANICAL PERFORMANCE OF MINING DRILL BITS USING HIGH-ENTROPY ALLOYS
type: item
description: This study explores the role and future prospects of high-entropy alloys (HEAs) in the mining and metallurgical industries. Due to their exceptional microstructural stability, high mechanical strength, wear resistance and heat tolerance, HEAs represent a promising alternative to conventional metallic materials used in drilling tools, cutting elements and components operating under extreme loading conditions. In this research, an AlCoCrNi-based HEA was synthesized, its phase composition was analyzed, and the effects of heat treatment on microstructural evolution and mechanical performance were investigated. Experimental field trials demonstrated that HEA-based drilling elements exhibited enhanced durability and operational stability compared with conventional alloys. The findings indicate that HEAs offer significant advantages in extending equipment lifetime, improving reliability and reducing maintenance costs within the mining industry. The obtained results provide scientific and practical foundations for further optimization and industrial implementation of HEA-based materials.

ПОВЫШЕНИЕ ЭФФЕКТИВНОСТИ СИСТЕМЫ АВТОМАТИЧЕСКОГО УПРАВЛЕНИЯ ИНДУКЦИОННОГО АГРЕГАТА
type: item
description: В работе рассматриваются принципы повышения эффективности системы автоматического управления индукционного агрегата и особенности тепловых процессов в индукционной тигельной печи. Проанализировано влияние уровня заполнения тигля, электромагнитных сил, тепловых потерь и формы расплава на общие энергетические характеристики установки. Показано, что традиционные методы регулирования температуры, основанные на переключении ступеней напряжения или изменении частоты, обладают высокой инерционностью и недостаточной адаптивностью, что приводит к перерасходу электроэнергии и снижению стабильности теплового режима. Представлен комплекс методов повышения эффективности САУ: совершенствование алгоритмов управления, внедрение адаптивных, предиктивных и интеллектуальных регуляторов, повышение точности измерительных систем, модернизация силовой электроники, оптимизация электромагнитных режимов и применение цифровых двойников. Рассмотрен пример расчёта энергетической эффективности, показывающий снижение годового энергопотребления на 24192 кВт·ч после модернизации САУ. Показано, что использование косвенных электрических параметров для оценки температуры расплава и применение математической тепловой модели позволяют существенно повысить точность управления и стабильность технологического процесса. Сделан вывод о необходимости перехода к интеллектуальным системам автоматического управления, основанным на комплексной оценке теплового состояния агрегата.

O‘ZBEKISTONDA QISHLOQ XO‘JALIGI VA QAYTA TIKLANUVCHI ENERGETIKANING BARQAROR RIVOJLANISHIDA AGROVOLTAIKANING ROLI
type: item
description: Maqolada qayta tiklanuvchi energiya manbalarining (QTM) global rivojlanishi, xususan, quyosh energetikasiga e’tibor qaratilib, uning aholining o‘sishi, oziq-ovqat xavfsizligi va suv resurslari muammolarini hal etishdagi ta’siri tahlil qilinadi. Alohida e’tibor agrovoltaikaga – quyosh panellari ostida bir vaqtning o‘zida elektr energiyasi va qishloq xo‘jaligi mahsulotlari ishlab chiqarish texnologiyasiga qaratiladi. BMT, FAO va O‘zbekiston Energetika vazirligi ma’lumotlariga asoslanib quyidagi chaqiriqlar ko‘rib chiqiladi: aholining 2050 yilga borib 9,7 milliardgacha o‘sishi, Markaziy Osiyoda suv tanqisligi (sug‘orishda 50% gacha yo‘qotishlar) va tuproq unumdorligining sho‘rlanish hamda eroziya tufayli kamayishi. O‘zbekistondagi muvaffaqiyatli pilot loyihalar muhokama qilinadi: Toshkent viloyatidagi 10 kVt stansiya (suv iste’molini 10–15% ga kamaytirish), Farg‘ona viloyatida uzumzorlar uchun 5 MVt quvvatli loyiha va Sirdaryo viloyatida malina yetishtirish uchun yarim shaffof panellardan foydalanilgan 60 kVt quvvatli loyiha. Global agrovoltaika bozori 14 GVt o‘rnatilgan quvvatga baholanib, 2032 yilgacha 11,14 milliard dollargacha o‘sishi prognoz qilinmoqda. Texnologiya yer resurslaridan ikki yoqlama foydalanishga, hosilni jaziramadan himoya qilishga va samaradorlikni 10–20% ga oshirishga yordam beradi. Bu O‘zbekiston uchun 2025 yilgacha 7 GVt QTMga erishish kontekstida dolzarbdir.

TECHNOLOGY FOR MANUFACTURING LIGHTWEIGHT SPINDLES OF COTTON-PICKING MACHINES
type: item
description: Nowadays, a wide variety of cotton harvesting machines are manufactured in different countries to collect the cotton crop. Among them, vertical spindle cotton harvesters occupy a unique position in the development of the cotton industry and harvesting machinery, despite their slightly lower harvesting efficiency compared to some other types. Throughout their evolutionary development, vertical spindle cotton harvesters have undergone numerous structural and technological modifications. However, the main working element—the spindle system—still presents significant challenges. Extensive experimental studies have been conducted by numerous researchers to improve spindle performance. Although several spindle designs have been proposed, none have yet fully resolved all existing issues. One of the most pressing problems is the relatively heavy mass of the spindle, which places excessive mechanical load on the driving mechanisms. As a result, these mechanisms often suffer from reduced operational reliability and tend to fail prematurely, before the end of their intended service life. This article presents a step-by-step analysis of the design and production technology of a lightweight spindle structure developed in accordance with modern engineering requirements. The proposed technological solution aims to enhance the overall efficiency of vertical spindle systems, improve operational performance, and extend the service life of the cotton harvester’s core components.

NEW NAMES IN THE KARAKALPAK ANTHROPONOMICAL SYSTEM
type: item
description: This article deals with the analysis of personal names that have appeared in the Karakalpak anthroponomical system in recent times. A review of the material shows that the modern anthroponomical system is undergoing a renewal process through the introduction of new units from other languages, the use of traditional anthroponomical formants, and the integration of borrowed elements within a single anthroponym. A partial return to the historical anthroponomical system is also evident.

KEY CONCEPTS AND PRINCIPLES OF THE ANTHROPOCENTRIC PARADIGM IN LINGUISTICS
type: item
description: This article explores the foundational concepts and principles of the anthropocentric paradigm in linguistics. By analyzing its development, philosophical underpinnings, and major linguistic directions, the study highlights the shift from object-centered to human-centered linguistic inquiry. The anthropocentric paradigm's influence is traced through cognitive linguistics, linguoculturology, and paremiology. The article also examines the implications of anthropocentrism for lexicography and phraseography. The findings demonstrate the paradigm's pivotal role in shaping contemporary linguistic methodologies and reinforce its enduring significance across diverse schools of thought.

THEORETICAL FOUNDATIONS OF THE CONCEPT OF LACUNA IN LINGUOCULTURAL AND TRANSLATION STUDIES
type: item
description: The article discusses the concept of lacuna, its classification, its manifestations in intercultural communication, and its role in translation studies. It also emphasizes the issue of achieving balance in translation with the example of English-Uzbek and Uzbek-English comparisons. Approaching the term “lacuna” from the linguocultural point of view is highly supportedin the article. It is proved that the study of lacuna in the linguocultural aspect has a number of advantages. This approach can help to understand the lacuna in integrity, in all its beauty, to see deeper foundations of the lacuna, and to open up new perspectives and opportunities for understanding intercultural communication. In particular, we stand for the use of linguocultural analyses in Uzbek-English translation fiction, the languages, which are distant from each other, because in prose works there are many lexical units with a clear linguocultural component, and in most cases they are given the decisive roles as expressing the literary value and idea of the work. Deep background knowledge is required to properly understand and translate these lexical units. Insufficient understanding and incorrect translation can lead to misunderstandings and cultural errors in communication. In this context, this paper aims to show the benefits of a deeper and combined study of the lacuna in linguistic and cultural aspects. It is also stated in the article, that due to the complex and multifaceted nature of the lacuna, classifying them into a single principle becomes a very difficult task. It is only natural that a lacuna may be associated with a classification system based on a specific aspect of the lacuna, since one lacuna may belong to more than one classification system at a time. Contrary to a number of scholars, we emphasize the need for both lacuna studies to be conducted both synchronously and diagonally.
