This article presents the results of surgical treatment of purulent corneal ulcers in 17 patients by the method of autoconjunctival plasty in combination with tarsorraphy. The article describes in detail the technique of the operation and its main advantages. The authors have shown the effectiveness of the proposed method, which is expressed in the fact that in ease of purulent corneal ulcers, the proposed method allows you to preserve the anatomical integrity of the eyeball and improve the patient's rehabilitation process after surgery.

The paper studies the physicochemical properties of import-substituted and export-oriented nitrogen, amine and phosphorus new composite inhibitors for corrosion protection of steels as well as scaling obtained from local raw materials and industrial wastes. Inhibiting properties of corrosion and mineral salt deposit accumulation in acid and hydrogen sulfide environments have been determined. It was found that the efficiency of the inhibition process with the use of composite inhibitors in acidic and hydrogen sulfide environments obeys the Langmuir law. The values of activation energy of the adsorption process in these media and thermodynamic values (∆H, ∆S, ∆G).
Currently, the Republic of Uzbekistan deservedly pays attention to the introduction of inhibitors to protect equipment from corrosion and scaling in production. The use of inhibitors allows several times to increase the service life of expensive equipment. In this regard, the most effective inhibitors of neutral and slightly alkaline media are nitrogen, amine and oxygen-containing organic compounds [1-3] as well as zinc organophosphonic acids, which effectively prevent corrosion and deposits of mineral salts on the surface of equipment.
Мақолада турли жуфтлаш вариантларида қоракўл қўйларининг рангбарангликлар, гул типлари ва синфларининг наслга берилиши бўйича олиб борилган тадқиқот натижалари ёритилган.
In children’s tuberculosis inpatient departments of the PMCforPhandP and the Tashkent city tuberculosis hospital, 272 children and adolescents with various forms of tuberculosis were examined. Among children with various forms of tuberculosis, 28(10,3%) patients were diagnosed with complicated forms and 244 (89,7%)-uncomplicated forms of tuberculosis. When studying the risk factors for the disease, it was revealed that there were 225 (87,7%) children vaccinated with BCG, of which 58 (25,8%) children (76,8%), of whom anemia was found in 35 (12,9%) patients. In the structure of clinical forms in childrenand adolescents with tuberculosis, tuberculosis of the intrathoracic lymph nodes (57,0%) and primary tuberculosis complex (11,0%) predominate. Most of the children hada positivity to tuberculin (77,5±2,5%) and to the test for Diaskintest (69,5±2,7%).
Shaxsni tanib olish biometrik texnologiyalari kirish-chiqishni nazorat qilish, bank, ichki ishlar, ta’lim kabi sohalarda keng qo‘llanilmoqda. Amaliyotda esa barmoq izi, yuz tasviri, ko‘z qorachig‘i, kaft va qon tomirlariga asoslangan tanib olish tizimlari keng joriy etilgan. Ishonchli va arzon biometrik tizimlarga bo‘lgan talablar kun sayin ortib bormoqda. Biometrkani har bir yo‘nalishi qo‘llanish sohasiga ko‘ra o‘ziga xos yutuq va kamchiliklarga ega. Hozirgi kunda kaft tasviri asosida shaxsni identifikatsiyalash zamonaviy vositalar hisobiga tez rivojlanmoqda. Bunga undan foydalanish sodda va qulayligi, emotsional betarafligi, faqat kamerani talab qilishi kabilar sabab bo‘lmoqda.
Mazkur maqola kaft tasviri bo‘yicha shaxsni identifikatsiyalash vositalari tadqiqiga bag‘ishlangan bo‘lib, unda kaft tasvirini onlayn olish qurilmalari, ularni yutuq va kamchiliklari, qulayliklari keltirib o‘tilgan.
Maqolada sun’iy intellektdan ta'limni boshqarishda foydalanish afzalliklari ko’rib chiqilgan bo’lib, unda sun’iy intellektdan foydalanib talabalar faolligi, ularni bilim va ko’nikmalarini oshirish, ta’lim olishni individuallashtirish, iqtisodiy samaradorlikni oshirish va ta'lim boshqaruvini yaxshilash muammolari yechimlari bayon etilgan.
Artificial Intelligence in Education (AIED) is rapidly evolving, offering innovative possibilities to transform the way we approach learning and teaching. While AIED initially focused on automating traditional educational practices, its potential extends far beyond that. This review paper explores how AIED can offer more than mere automation and why it is crucial to consider its role in supporting collaborative learning, student forum monitoring, continuous assessment, AI learning companions, AI teaching assistants, and as a research tool to enhance the learning sciences. By examining these facets, we aim to shed light on the exciting opportunities that AIED can bring to education while acknowledging the complex challenges and ethical considerations involved.
Mazkur maqolada ochiq manbali nutqni tanib olish texnologiyalari tahlili keltirilib, unda ularning foydalanish imkoniyatlari baholangan va ushbu tadqiqot doirasidagi tahlillar nutqni aniqlash tizimlarining kelajagini shakllantirishda ochiq manbali tizimlar ta'siri yoritilgan.
Hozirgi vaqtda turli xil tasvirga olish qurilmalaridan olingan raqamli tasvirlar soni keskin oshib bormoqda. Ayrim hollarda ushbu tasvirlar tasvirga olish, qayta ishlash, siqish, saqlash, uzatish va ko’paytirish jarayonida turli shovqinlardan ta’sirlanib, sifatsiz holatga kelishi mumkin. Shovqin tasvirdagi ma’lumotlarning sifatini buzadigan tasodifiy o’zgarishlarni ifodalaydi va tasvirdan muhim ma’lumotlarni olishga to’sqinlik qiladi. Bu o’z navbatida, tasvirda uchraydigan asosiy shovqin turlarini o’rganish tasvirlash sohasida dolzarb ekanligini ko’rsatadi. Mazkur tadqiqot ishi Gauss, tuz va qalampir, uniform, Puasson, spekl, rayleigh va risian kabi shovqin turlarini o’rganishga bag’ishlangan.
