Mazkur maqolada Yevropa va Rossiya ishlab chiqaruvchilariga mansub yog‘och qirindisi (DSP), yog‘och tolali (MDF) hamda ularning laminatlangan turlari (LDSP, L-MDF) ning fizik-mexanik xossalari eksperimental tadqiq etildi. Tadqiqotlar O‘zDSt 3478-2020, GOST 10632-2014 va GOST 32289-2013 standartlari asosida laboratoriya sharoitida amalga oshirildi. Sinov natijalariga ko‘ra, Yevropa ishlab chiqaruvchilarining mahsulotlari yuqori zichlik (715–830 kg/m³) va egilishdagi mustahkamlik (15,3–30,8 MPa) ko‘rsatkichlariga ega ekanligi aniqlandi. Shuningdek, laminatlash texnologiyasi materiallarning mustahkamligini oshirishi va suv ta’sirida shishish darajasini kamaytirishi tajriba asosida tasdiqlandi. Barcha namunalar normativ talablarga javob bergan bo‘lsa-da, Rossiya va boshqa ishlab chiqaruvchilar mahsulotlarida ayrim ko‘rsatkichlar pastroq qiymatlarni namoyon etdi. Tadqiqot natijalari yog‘och asosli plitalarning sifat ko‘rsatkichlari ishlab chiqarish texnologiyasi va xomashyo xususiyatlariga bog‘liqligini ko‘rsatadi hamda ularni takomillashtirish uchun ilmiy asos yaratadi.

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.

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.
