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.

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 study, using a sequential explanatory mixed design, comprehensively examined the prevalence, severity, and sources of English learning anxiety among Afghan male students learning English as a foreign language at Paktika Institute of Higher Education. In the quantitative part of the study, data were collected from 87 valid respondents using the Foreign Language Classroom Anxiety Scale (FLCAS). Descriptive analyses revealed that 69% of the students experienced moderate anxiety and 21.8% experienced high anxiety. Among the various factors, fear of negative evaluation and fear of communication were identified as the most prominent concerns and sources of anxiety. In the qualitative phase, data were collected through purposeful semi-structured interviews with 12 participants and analyzed using thematic analysis. The analysis revealed five main themes, which were: fear of negative evaluation, fear of communication, limitations in English exposure and practice, the influence of teacher and peer behavior, and anxiety related to tests and performance. Participants detailed how classroom dynamics, the lack of appropriate environments for using English outside the classroom, and high-risk and stressful assessments contributed to their increased anxiety levels. The findings of this study emphasize the multifaceted and context-dependent nature of language anxiety and show that language learning anxiety among Afghan learners is influenced by multiple cultural, environmental, and educational factors. They also highlight the urgent need to adopt supportive teaching approaches, provide more opportunities for language practice in real-world and informal settings, and train teachers to better manage students’ anxiety.
