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.

This article studies the lexical-semantic properties of units expressing the mental state of a person in the Uzbek language. The semantic analysis of these units, their use in context and their role in the speech structure are studied. The methods of lexical-semantic analysis, component analysis, contextual analysis and comparison were used in the research. The results show that units expressing the mental state in the Uzbek language have their own semantic changes in different contexts, which play an important role in increasing the expressiveness of speech. The role of these units in modern speech and literary language is also considered.

Mazkur maqolada islom dinida tabiat va atrof-muhitga bo‘lgan munosabatning Qur’oni karim asosidagi tahlili yoritiladi. Qur’oni karim oyatlari asosida insonning tabiat oldidagi mas’uliyati, ekologik muvozanatni saqlash borasidagi ilohiy ko‘rsatmalar, isrofgarchilik va ifloslantirishdan tiyilish kabi tamoyillar ilmiy asosda yoritiladi.

Ushbu maqolada “Uz CLAAS Agro” MChJ faoliyati misolida aylanma mablag‘larni boshqarish jarayoni tahlil qilinadi va ularning samaradorligini oshirish bo‘yicha amaliy takliflar ishlab chiqiladi. Aylanma mablag‘lar korxonaning qisqa muddatli moliyaviy holatini belgilovchi muhim resurs bo‘lib, ularni oqilona boshqarish ishlab chiqarish barqarorligi, likvidlik va foyda ko‘rsatkichlariga bevosita ta’sir ko‘rsatadi. Maqolada korxonaning 2022–2024 yillardagi moliyaviy ko‘rsatkichlari asosida tahlil o‘tkazilib, debitor qarzdorlikni, ombor zaxiralarini optimallashtirish hamda raqamli boshqaruv tizimlarini joriy etish orqali aylanma mablag‘lar aylanishini tezlashtirish yo‘llari ko‘rib chiqiladi. Tadqiqot natijalari asosida korxonaga moliyaviy barqarorlikni ta’minlash va resurslardan samarali foydalanishga qaratilgan konkret takliflar berilgan.

Ushbu maqolada ta’lim tizimi jarayonidagi STEAM texnologiyasi dasturi haqida ma’lumotlar yoritilgan. Bundan tashqari, boshlang’ich sinflarda STEAM yondashuvi asosida integratsiyalashgan ta’limning afzalliklari va erishiladigan yutuqlari haqida mulohazalar yuritilgan. Shuningdek, zamonaviy ta’limda STEAM yondashuvi orqali o’quvchilarning amaliy bilim va ko’nikmalarini rivojlantirish, ta’limni hayot bilan bog’lash imkoniyatlari ochib beriladi.
