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.

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.

Mazkur maqolada bokschilarni bir yillik o‘quv-mashg‘ulot sikli davomida tayyorlash metodikasi, mashg‘ulot yuklamalarini rejalashtirish tamoyillari hamda sport natijalarini oshirishga qaratilgan uslublar tahlil qilingan. Tadqiqotda tayyorgarlik davri, musobaqa davri va o‘tish davrlarining o‘zaro bog‘liqligi, jismoniy, texnik-taktik hamda psixologik tayyorgarlikning yillik sikldagi o‘rni yoritilgan. Shuningdek, mashg‘ulot jarayonini ilmiy asosda tashkil etishning samaradorligi statistik ma’lumotlar va tahlillar orqali ko‘rsatib berilgan.

Mazkur maqolada Jamoliddin Ibn Hojibning “Al-Kofiya” hamda Abdurahmon Jomiyning “Al-Favaidu ad-diyaviyyatu” asarlarida sintaktik talqinlarning qiyosiy tahlili amalga oshiriladi. Tadqiqotda ikki asarning metodologik yondashuvlari, grammatik ta’riflari va nahviy masalalarga munosabati o‘rganilgan. Xususan, foil, tavobi’, taqdim va ta’xir hamda tanozu’ kabi sintaktik hodisalarning talqinidagi o‘xshash va farqli jihatlar yoritilgan. Tahlillar natijasida Ibn Hojib grammatik qoidalarni ixcham va me’yoriy shaklda bayon etgani, Jomiy esa ularni mantiqiy-semantik jihatdan keng sharhlab bergani aniqlandi.
