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.

Ushbu maqolada jinsiy sistema kasalliklarning yildan yilga yosh toifasini oʻzgarishi - ya'ni yosharishi haqida so‘z boradi. Masalan hozirgi kunda qiz bolalar va yosh qizchalarda ham jinsiy sistema kasalliklari kuzatiladi. Bu, hayz funksiyasining buzilishi va jinsiy aʼzolar rivojlanishidagi anomaliyalardir. Bunga, asosan, uning bolaligida boshidan kechirgan turli kasalliklari, noqulay turmush tarzi, hatto u ona qornidaligidayoq onasining birorbir jiddiy kasallik bilan ogʻriganligi sabab boʻlishi mumkin. Hayz funksiyasining buzilishi qizlarda hayzning kech yoki erta boshlanishi, nomuntazamligi, qon ketishi va hokazo lar bilan kechadi. Maqolaning mohiyatida jinsiy sistema kasalliklarning yildan yilga ko‘payishining oldini olish hamda ularni davolash chora tadbirlari to‘g‘risida fikr mulohaza yurutiladi.

Ma'lumki, nikohga va yaqin qarindoshlikka asoslangan axloqiy mas'uliyat, o’zaro qurmat, tushunish va mehr-muhabbat umumiyligi bilan bog`langan kichik ijtimoiy guruh oila deyiladi. Oila boshqa turdagi kichik guruhlardan o’zining bir qator jihatlari bilan ajralib turadi: birinchidan, oila ko’p muddatga, ya'ni bir necha o’n yillar va ko’p yillarga mavjud bo’ladi; ikkinchidan, oilada shaxslararo munosabatlarning bir necha turlari amalga oshadi, ya'ni milliy mafkuramizga oid ilk tushunchalar avvalo oila muhitida singadi va bu jarayon bobolar o’giti, ota ibrati, ona mehri orqali amalga oshadi. Bunda oilaviy munosabatlarda tarbiyaviy, psixologik, xissiy, moliyaviy, jinsiy va boshqa vazifalarning amalga oshirilishi kuzatiladi;
