Ushbu maqolada Abu Tohirxo'janing "Samariya" asarida keltirilgan gidronimlar lingvistik va etimologik jihatdan tahlil qilingan. Asarda keltirilgan sakkizta asosiy suv obyekti nomlari tarixiy va zamonaviy manbalarga tayanib o'rganilgan. Tadqiqot natijasida gidronimlarning kelib chiqishi, ma'no xususiyatlari va hozirgi kundagi ahamiyati aniqlangan.

Ushbu maqola g‘arb pedagogikasining umumisoniy qadriyatlarini o‘rganishga bag‘ishlangan hamda ularning boshqa xalqlar umuminsoniy pedagogikasining rivojlanishida tutgan o‘rni, G‘arb ta’lim tizimida shakllangan asosiy tamoyillar, erkinlik, tenglik, inson huquqlari ijtimoiy adolat va demokratiya kabi qadriyatlar tahlil qilinadi.

Ushbu maqolada o‘zbek xalqining qadimiy san’at turi bo‘lgan baxshichilikning ta’limiy, tarbiyaviy va pedagogik imkoniyatlari chuqur tahlil qilinadi. An’anaviy musiqaning yosh avlodning ma’naviy kamolotiga ta’siri, estetik tarbiyada tutgan o‘rni, pedagogik jarayondagi samaradorlik jihatidan o‘rganiladi. Musiqa va xalq ijodiyotining integratsiyasi asosida zamonaviy ta’lim metodikasini boyitish imkoniyatlari yoritiladi.

Ушбу мақолада Туркистон ўлкаси тарихини тадқиқ этишда Россия империяси томонидан ўлка бошқаруви учун қабул қилинган меъёрий-ҳуқуқий ҳужжатлар ва қонунларнинг аҳамияти очиб берилади.

This article explores the fundamental principles of thermal power generation, focusing on core components and functions in thermal power plants. It covers thermodynamics, the Rankine cycle, and heat transmission rules, with detailed examination of Rankine cycles and heat transfer mechanisms in plant components. It also discusses internal combustion engines, particularly diesel engines, and Advanced Exergy-Based Analyses in system analysis. These analyses aim to identify preventable exergy destruction sources and costs within components, with ongoing development addressing issues like validating exergy dissipation divisions. Synthesis methodologies include superstructure-based and superstructure-free approaches. The former uses a steam network to create a steam-cycle superstructure, integrating with a heat exchanger network for comprehensive flowsheets. The latter employs SYNTHSEP and ECH-based methods, with the ECH-based method excelling in comprehensive flowsheet synthesis and offering easy expansion with precise models. Both methods use bi-level decomposition techniques combining evolutionary algorithms and mathematical programming.
