[ 1 ] - Determination of Protein and Moisture in Fishmeal by Near-Infrared Reflectance Spectroscopy and Multivariate Regression Based on Partial Least Squares
The potential of Near Infrared Reflectance Spectroscopy (NIRS) as a fast method to predict the Crude Protein (CP) and Moisture (M) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on Partial Least Squares (PLS) was evaluated. The coefficient of determination in calibration (R2C) and Standard Error of Calibra...
[ 2 ] - Photoluminescence quantitative analysis of Gallic acid and Caffeine in green tea using multi-way chemometric approaches
Green tea is considered as a dietary source of antioxidant nutrients, which acts upon human health. Green tea leaves contain three main components in the form of simple hydroxy benzoic acids such as gallic acid, propyl gallate and xanthic bases (caffeine), have been reported to prevent or delay a number of degenerative diseases and act mainly upon the central nervous system and stimulating wake...
[ 3 ] - An application of geometrical isometries in non-planar molecules
In this paper we introduce a novel methodology to transmit the origin to the center of a polygon in a molecule structure such that the special axis be perpendicular to the plane containing the polygon. The mathematical calculation are described completely and the algorithm will be showed as a computer program.
[ 4 ] - شناسایی ترکیبات با خواص ضداکسیدانی موثر در عصاره‌ی برگ گیاه گردو با استفاده از کروماتوگرافی مایع – طیف‌سنجی جرمی و روشهای کالیبراسیون چندمتغیره خطی
برگ گیاه گردو به دلیل اثرات گوناگون در دارو درمانی و طب سنتی شناخته شده است. این گیاه دارای خواص ضداکسیدانی و ضدمیکروبی خوبی می‌باشد. در این مطالعه، عصاره‌ی برگ گیاه گردو از مناطق مختلف ایران به‌وسیله‌ی دستگاه کروماتوگرافی مایع با عملکرد بالا-طیف‌سنجی جرمی مورد تجزیه قرار گرفت. نمونه‌ها از نظر فعالیت بازداری رادیکال آزاد، به‌وسیله‌ی سنجش 2، 2-دی فنیل 1- پیکریل هیدرازیل (DPPH) مورد آزمایش قرار ...
