Ushbu maqolada bioparchalanuvchi polimerlarga qo‘yiladigan xalqaro standartlar, ularning asosiy tamoyillari va ekologik baholash mezonlari tahlil qilinadi. Polimer materiallarning biologik parchalanish qobiliyatini baholashda qo‘llaniladigan eng muhim standartlar – ASTM D6400, EN 13432, ISO 17088 va boshqalar yoritiladi. Maqolada, shuningdek, ushbu standartlarning global amaliyotdagi o‘rni va ularni joriy etishdagi muammolar ko‘rib chiqilgan.

In recent decades, the prevalence of allergic respiratory diseases, such as asthma and allergic rhinitis, in children has been rising at an alarming rate. One of the key contributors to this trend is climate change, which has altered environmental conditions, exacerbating the frequency and intensity of allergens such as pollen, mold, and air pollutants. This paper examines the dynamics of the increasing incidence of allergic respiratory diseases in children under the conditions of climate change. It explores the key environmental factors-such as rising temperatures, longer pollen seasons, and worsening air quality-that contribute to this growing health concern. The paper also delves into the vulnerability of children, whose developing immune and respiratory systems make them more susceptible to environmental stressors. In addition, it emphasizes the importance of preventive measures, including environmental regulation, early detection, allergen avoidance strategies, and public health policies aimed at reducing exposure to harmful environmental factors.

Yashil kimyo zamonaviy kimyoviy sintezga innovatsion yondashuvni ifodalaydi va atrof-muhitga minimal zarar yetkazuvchi texnologiyalarni ishlab chiqishga qaratilgan. Ushbu maqolada ekologik jihatdan xavfsiz sintez usullarini qo‘llash samaradorligi tahlil qilinib, atom iqtisodiyoti, hal qiluvchi (solvent) ishlatilmaydigan reaksiyalar va katalitik tizimlardan foydalanish orqali chiqindilar hosil bo‘lishining oldini olish imkoniyatlari ko‘rib chiqiladi. Biokataliz, mikroto‘lqinli nurlanish yordamida sintez va superkritik suyuqliklar kabi muqobil reaksiya usullari ekologik va iqtisodiy samaradorlik nuqtayi nazaridan baholanadi. Sanoat va ilmiy tadqiqot muhitida yashil kimyo tamoyillarini integratsiyalash natijasida energiya samaradorligi, resurslardan oqilona foydalanish va xavfli moddalarning kamayishi kabi muhim yutuqlarga erishilmoqda. Shuningdek, turli sintez yo‘llarining ekologik ta’sirini miqdoriy baholash maqsadida hayotiy sikl tahlili usullari qo‘llaniladi. Tadqiqot davomida zararli reagentlar o‘rniga barqaror muqobillar qo‘llangan muvaffaqiyatli yashil sintez strategiyalarining amaliy misollari tahlil qilinadi.

Ushbu maqolada namanganlik shoir Mulla Yo‘ldoshxo‘ja Otaxo‘ja o‘g‘li Dog‘iyning lirik merosi haqida ma’lumot berilgan. Shoir she’rlarida mumtoz adabiyot an’analariga sodiqlik yaqqol ko‘zga tashlanib turadi. Buning misoli sifatida Dog‘iyning hamd va na’tlari tahlil ostiga olindi.
