Bugungi kundа Аfgʻоnistоn zаminidа dаvоm еtаyоtgаn nоtinсh vаziyаt nаtijаsidа jаfоkаsh аfgʻоn xаlqi аzоb-uqubаtlаrni bоshidаn kесhirmоqdа. Аfgʻоnistоndа yuz bеrаyоtgаn nоtinсh vаziyаtni hаl еtishdаn mаnfааtdоr bоʻlgаn tоmоnlаr yоki аksinсhа bundаy vаziyаtni dаvоm еtishidаn mаnfааtdоr bоʻlgаn kuсhlаr hаm mаvjud. Buning аsоsiy sаbаblаridаn biri sifаtidа, Аfgʻоnistоnning gеоgrаfik jоylаshuvigа kоʻrа hаm Mаrkаziy Оsiyо mintаqаsining xаvfsizlik vа rivоjlаnish istiqbоlidа shuningdеk, ikki mintаqаning bir-biri bilаn bоgʻlаnishidа kоʻprik vаzifаsini оʻtаshi bilаn muhim аhаmiyаt kаsb еtаdi.

This article examines modern observation methods used in educational settings to assess student activity and engagement during the learning process. Through a comprehensive analysis of contemporary pedagogical literature, the study investigates various systematic observation techniques, their theoretical foundations, and practical applications in classroom environments. The analysis reveals that structured observation protocols, when combined with technological innovations and culturally sensitive assessment frameworks, significantly enhance the accuracy and reliability of student activity evaluation.

This article investigates the use of CAD/CAE systems in additive manufacturing within Uzbekistan’s mechanical engineering industry. Based on international examples, it explores how digital design and simulation tools can be integrated with modern 3D printing technologies. The research highlights practical benefits such as improved efficiency, reduced costs, and higher product quality, supported by examples from global practice. The study also considers the potential impact of adopting these technologies in Uzbekistan, including opportunities for innovation, increased competitiveness, and sustainable industrial development. The findings provide recommendations for local enterprises and policymakers on how to effectively implement advanced manufacturing technologies while addressing local challenges.

Ushbu ilmiy maqolada inson asab tizimining murakkab neyroanatomik tuzilishi chuqur va tizimli yondashuv asosida tahlil qilinadi. Asab tizimi organizmning barcha hayotiy jarayonlarini boshqaruvchi, muvofiqlashtiruvchi va tashqi hamda ichki muhit o‘zgarishlariga moslashuvni ta’minlovchi yagona integrativ tizim sifatida qaraladi. Maqolada markaziy va periferik asab tizimlarining strukturaviy xususiyatlari, ularning o‘zaro bog‘liqligi, neyronlarning mikroskopik tuzilishi, biofizik xususiyatlari hamda funksional ahamiyati keng yoritilgan. Shuningdek, bosh miya va orqa miyaning anatomik tuzilishi, ularning segmentar va regional tashkil etilishi, reflektor faoliyatning morfologik asoslari va nerv tizimining yuqori darajadagi integrativ xususiyatlari ilmiy dalillar asosida izohlangan. Maqola zamonaviy neyrobiologiya, anatomiya va fiziologiya fanlari yutuqlariga asoslangan bo‘lib, tibbiyot talabalari, magistrantlar, rezidentlar hamda ilmiy tadqiqotchilar uchun muhim nazariy manba sifatida xizmat qiladi.

Ushbu ilmiy maqolada inson organizmidagi to‘qimalarning fiziologik va reparativ regeneratsiyasi, ularning yangilanish mexanizmlari hamda to‘qimalar o‘zgaruvchanligining biologik chegaralari ilmiy jihatdan tahlil qilinadi. Regeneratsiya organizmning muhim biologik xususiyatlaridan biri bo‘lib, u to‘qimalarning shikastlanishdan keyin tiklanishi va normal faoliyatni saqlashida muhim rol o‘ynaydi. Maqolada turli to‘qima turlarining regeneratsiya qobiliyati, hujayra proliferatsiyasi, differensiallanish jarayonlari va ularni boshqaruvchi molekulyar mexanizmlar yoritilgan. Shuningdek, fiziologik regeneratsiya bilan reparativ regeneratsiya o‘rtasidagi farqlar, regeneratsiya tezligi va samaradorligiga ta’sir etuvchi omillar ham ilmiy asosda ko‘rib chiqiladi. To‘qimalar o‘zgaruvchanligi chegaralari, ya’ni hujayralarning morfologik va funksional o‘zgarish imkoniyatlari ham tahlil qilinadi. Ushbu masala zamonaviy tibbiyot, histologiya va regenerativ biologiya uchun muhim ahamiyatga ega.
