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.
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.
Pneumonia is a significant cause of morbidity and mortality in children with congenital hydrocephalus, posing unique challenges in diagnosis and treatment. This study aims to explore the specific features of pneumonia progression in children born with hydrocephalus, focusing on the interplay between neurological impairments and respiratory vulnerability. Hydrocephalus, a condition characterized by the abnormal accumulation of cerebrospinal fluid in the brain, can lead to various neurological deficits, which in turn increase the susceptibility to respiratory infections, including pneumonia. The study employs a retrospective analysis of clinical data from pediatric patients diagnosed with hydrocephalus who were also treated for pneumonia. Data were collected on the clinical presentation, diagnostic methods, treatment protocols, and outcomes of pneumonia in these patients. Key findings revealed that children with hydrocephalus often present with atypical pneumonia symptoms, including lethargy, irritability, and feeding difficulties, which complicates early diagnosis. Furthermore, respiratory defense mechanisms in these children are compromised due to poor neuromuscular control and swallowing dysfunction, leading to an increased risk of aspiration pneumonia.
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.
