Ushbu maqola bedanalar ratsioniga gidroponik usulda yetishtirilgan ozuqalarni qo'shish orqali parrandachilik sohasida erishiladigan afzalliklarni o'rganadi. Tadqiqotda gidroponik yem-xashak yetishtirish texnologiyalari, ularning ozuqaviy qiymati va bedanalar ratsionida qo'llanilishi, shuningdek, ushbu usulning iqtisodiy va ekologik jihatlari tahlil qilinadi. Natijalar gidroponik ozuqalarning bedanalar salomatligi, mahsuldorligi va mahsulot sifatiga ijobiy ta'sirini ko'rsatadi hamda an'anaviy ozuqalarga nisbatan bir qator ustunliklarini aniqlaydi.

Mazkur maqolada OIV infeksiyasiga chalingan bemorlarga retrovirusga qarshi terapiya jarayonida hamshiralar tomonidan ko‘rsatiladigan tibbiy va psixologik yordamning ahamiyati yoritiladi. Hamshiralar bemorlarning dori vositalarini to‘g‘ri qabul qilishini ta’minlash, ularning salomatligini kuzatish, muqobil tibbiy yordam ko‘rsatish va psixologik qo‘llab-quvvatlashda muhim rol o‘ynaydi. Shuningdek, maqolada hamshiralarning kasallik profilaktikasi, infeksiyaning tarqalishini oldini olish va bemorlarning hayot sifatini yaxshilashdagi o‘rni tahlil qilinadi. Tadqiqot natijalari sog‘liqni saqlash tizimidagi hamshiralar faoliyatini takomillashtirish hamda OIV bilan kasallangan bemorlarni parvarish qilish bo‘yicha samarali strategiyalarni ishlab chiqishga qaratilgan tavsiyalarni o‘z ichiga oladi.

The importance of studying and analyzing the management field, especially the organizational-economic, social, cultural-educational significance of management in the field of management, has been studied and methodologically studied.

Ushbu maqolada azot to'plovchi bakteriya shtammlarining soya (Glycine max L.) o'simligi bilan simbiotik munosabatlari tadqiq etilgan. Turli bakterial shtammlarning soya o'simligida azot fiksatsiyasi samaradorligi, simbiotik munosabatlar shakllanish mexanizmlari, atrof-muhit omillarining ta'siri, shuningdek, biotexnologik yondashuvlar tahlil qilingan. Tadqiqot natijalariga ko'ra, samarali simbiotik munosabatlar hosildorlikni 20-30% ga oshirishi, tuproq unumdorligini yaxshilashi va mineral o'g'itlar sarfini kamaytirishi aniqlangan.

The determination of metal ions such as Cu²⁺ and Zn²⁺ in various samples is crucial for environmental monitoring, industrial quality control, and biomedical applications. This study explores the quantitative analysis of Cu²⁺ and Zn²⁺ ions using UV/Vis spectrophotometry, a rapid and reliable technique based on the absorption of light by metal-ligand complexes. Optimal conditions for the detection, including wavelength selection, reagent concentration, and pH, were investigated to enhance sensitivity and accuracy. Calibration curves were constructed to determine the linearity and detection limits for each ion. The method was applied to real samples, and results were validated against standard techniques. The findings demonstrate that UV/Vis spectrophotometry provides a cost-effective and efficient approach for Cu²⁺ and Zn²⁺ determination in various matrices.
