Mazkur maqolada o‘zbek mumtoz adabiyotida balog‘at san’atlarining ifodalanishi va uslubiy xususiyatlari tahlil qilinadi. Tadqiqotda badiiy san’atlarning mumtoz matndagi vazifasi, ularning ma’no hosil qilishdagi o‘rni hamda uslubiy-estetik ta’siri yoritiladi. Asosiy e’tibor tashbeh, isti’ora, kinoya, tazod, talmeh va lafziy san’atlarning o‘zbek mumtoz poetikasidagi funksional tabiatiga qaratiladi. Taroziy, Husayniy, Navoiy va Boburga oid nazariy hamda badiiy manbalar asosida balog‘at san’atlarining obraz yaratish, ruhiy holatni ifodalash, ramziy qatlamni kuchaytirish va matnning musiqiyligini ta’minlashdagi roli ochib beriladi. Natijada o‘zbek mumtoz adabiyotida balog‘at san’atlari tashqi bezak emas, balki poetik tafakkurning ichki qonuniyatini yuzaga chiqaruvchi faol badiiy mexanizm ekani asoslanadi.

Ushbu maqolada raqamli muhitning yoshlar psixologik salomatligiga ko‘rsatadigan ta’siri ilmiy-nazariy jihatdan tahlil qilinadi. Axborot-kommunikatsiya texnologiyalarining jadal rivojlanishi natijasida internet, ijtimoiy tarmoqlar, mobil ilovalar va turli onlayn platformalar yoshlar hayotining ajralmas qismiga aylanib bormoqda. Raqamli muhit ta’lim olish, axborot almashish, muloqot qilish va shaxsiy rivojlanish uchun keng imkoniyatlar yaratishi bilan bir qatorda, yoshlarning ruhiy holatiga ma’lum darajada salbiy ta’sir ko‘rsatishi ham mumkin. Maqolada ijtimoiy tarmoqlardan me’yoridan ortiq foydalanish oqibatida yuzaga keladigan internet qaramligi, stress, xavotir, depressiv holatlar, uyqu buzilishlari, emotsional zo‘riqish va ijtimoiy izolyatsiya kabi muammolar yoritilgan. Shuningdek, virtual muloqotning real ijtimoiy munosabatlarga ta’siri, ijtimoiy taqqoslash jarayoni natijasida o‘zini past baholash holatlari hamda “like” va obunachilar soniga bog‘liq psixologik bosim masalalari tahlil qilingan. Yoshlarning psixologik salomatligini saqlash va mustahkamlashda raqamli gigiyena, media savodxonlik, vaqtni samarali boshqarish hamda sog‘lom turmush tarzining ahamiyati asoslab berilgan. Maqola yakunida raqamli muhitdan ongli, xavfsiz va me’yorida foydalanish orqali yoshlarning psixologik barqarorligini ta’minlash bo‘yicha amaliy tavsiyalar ishlab chiqilgan.

This article studies the targeted synthesis of nitro derivatives of polycyclic aromatic hydrocarbons, in particular, the process of obtaining 9-nitroanthracene, which is an important intermediate in organic electronics and medicinal chemistry. Analysis of classical literature data shows that the formation of by-products such as polynitro derivatives and anthracene-9,10-dione (anthraquinone) in direct nitration reactions of the anthracene nucleus, as well as the low yield of the target product, are fundamental problems. In order to eliminate the shortcomings noted in this study and increase the efficiency of the process, an optimal preparative method for the synthesis of 9-nitroanthracene derivatives with high regioselectivity was developed and its kinetic laws were studied. The molecular and electronic structure of the synthesized subject was analyzed in depth using a set of modern physicochemical methods. Infrared (IR) spectroscopy revealed asymmetric (1520 ) and symmetric (1340 ) stretching vibrations of the nitro group and absorption bands of the bond, while ultraviolet (UV) spectra revealed bathochromic shifts due to π→π* and n→π* electronic transitions of the anthracene nucleus and the nature of the conjugated system. The results obtained are of significant practical importance in the field of molecular optoelectronics, sensors, and the synthesis of luminophores, and provide a basis for obtaining biologically active amino derivatives.

Ushbu maqolada Mirzacho‘l vohasida shakllangan an’anaviy etnointegratsion jarayonlar, turli etnik guruhlarning o‘zaro munosabatlari, madaniy aloqalari va integratsiya omillari tahlil qilingan. Shuningdek, migratsiya, xo‘jalik faoliyati, oilaviy munosabatlar va mahalla institutining etnomadaniy uyg‘unlashuvdagi o‘rni yoritilgan.

Mazkur maqolada yosh sportchilarning mashg‘ulot jarayonida psixologik chidamkorligini rivojlantirishning nazariy va amaliy asoslari tahlil qilingan. Psixologik chidamkorlikning sport natijalariga ta’siri, uning shakllanishiga ta’sir etuvchi omillar hamda mashg‘ulotlar davomida qo‘llaniladigan zamonaviy psixologik usullar yoritilgan. Tadqiqot davomida yosh sportchilarning psixologik holatini baholash natijalari tahlil qilinib, psixologik tayyorgarlikni takomillashtirish bo‘yicha tavsiyalar ishlab chiqilgan. Olingan natijalar sportchilarni musobaqalarga tayyorlash jarayonida psixologik omillarning muhim ahamiyat kasb etishini ko‘rsatdi.
