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.

Moliya bozori zamonaviy iqtisodiy tizimlarda investitsiya faoliyati, risklarni boshqarish va kapital resurslarini optimal taqsimlashda muhim rol o‘ynaydi. Ushbu maqolada moliya bozori tahlili asosida samarali moliyaviy qarorlar qabul qilishning nazariy va amaliy jihatlari chuqur o‘rganilgan. Tadqiqotning asosiy maqsadi — investorlar, kompaniyalar va moliyaviy institutlar uchun moliyaviy qaror qabul qilishda moliya bozorining turli segmentlari (fond bozori, obligatsiyalar bozori, valyuta bozori, derivativlar bozori) tahlilining samaradorligini aniqlashdir. Maqolada fundamental tahlil, texnik tahlil va kvantitativ modellashtirish usullarining afzalliklari, ularning qarorlar sifatiga ta’siri tahlil qilingan. Shuningdek, so’ngi yillar oralig‘ida O‘zbekiston moliya bozorining asosiy statistik ko‘rsatkichlari tahlil etilib, fond bozorida IPOlar sonining ortishi, valyuta kursining barqarorligi va moliyaviy xizmatlar sifati bo‘yicha o‘sishlar qayd etilgan. Ushbu tahlillar asosida investorlar va boshqaruv subyektlari uchun strategik qarorlar qanday shakllanishi mumkinligi ko‘rsatib berilgan. Maqola yakunida esa raqamli texnologiyalarning (AI, Big Data, Fintech) moliyaviy tahlil vositalariga ta’siri va ularning qaror qabul qilishda kelajakdagi roli yoritilgan.
