[ 1 ] - Development and application of a new sensitive spectrophotometric-multivariate calibration method to the simultaneous determination of hydrazine and acetylhydrazine using silver nanoparticles
In this paper, multivariate calibration methods of partial least squares (PLS) and principle component regression (PCR) were investigated in simultaneously determination of hydrazine (HZ) and acetylhydrazine (AHZ). The aforementioned methods are based on formation of the silver nanoparticles (AgNPs) from the reaction of HZ and AHZ with Ag+ ions as oxidizing agent in the presence of citrate ions...
[ 2 ] - رابطه بین سطح سرمی کلسیم و قند خون نوزادان مبتلا به زردی غیرکونژوگه تغذیه کننده از شیر مادر با سطح سرمی بیلیروبین مستقیم و غیرمستقیم و مقایسه با جنسیت
Background: One of the most important bilirubin nervous receptors is N-Methyl-D-Aspartate (NMDA). Some parents believe that the aqueous solution of sugar reduces the bilirubin serum level in newborns. In this work, the relationship between newborns jaundice and the levels of serum calcium and blood sugar was investigated. Methods: This descriptive analytical study was performed on 102 icteri...
