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.
O‘ziga xos badiiy-estetik strukturaga ega yirik epik janr – roman strukturasida insonning shaxsiy hayotiga bog‘liq muammolargina emas, jamiyat hayoti, davlat boshqaruvi, siyosiy-mafkuraviy muammolar ham tasvirlanadi. Bular badiiy ijod namunasi matnidagi diskurs vositasida kitobxonga yetkaziladi. Ushbu maqolada Abdulla Qahhorning “Sarob” romani matnidagi qahramonlararo muloqot va ularning ichki monologi orqali ifodalangan diskurs tahlil qilindi.
Бухоро амирлигининг иқтисодий, сиёсий ва маданий ҳаётини акс эттирадиган ЎзР МДАнинг “Бухоро амирлиги Қўшбеги маҳкамаси” (Управление кушбеги эмира Бухарского) деб номланган И-126 фонди ҳам ўзига хос тарихга эга. Ёзма маълумотларга кўра, тарихчилар орасида Қўшбеги архиви деб ном олган ҳужжатлар тўплами ўтган асрнинг 30-йилларида Бухоро Аркидан топилган бўлиб, унинг Марказий Давлат Тарих архивига топширилиши, яъни марказ Тошкентга олиб келиниши ўша даврдаги мураккаб иқтисодий-сиёсий вазиятда амалга оширилган.
Ushbu maqolada arab tilshunosligining rivoji uchun katta hissa qo‘shgan yurtdoshimiz Mahmud Zamaxshariy, uning hayoti va ijodi asarlari asosan “Al- Mufassal” kitobi xususida yoritiladi. Asar qayerda yozilganligi qanday tartibda berilganligi ya’ni ketma-ketligi haqida fikr yuritiladi. Shuning حرف جر lar haqida ham qisqacha aytib o‘tilgan.
