Replacement Orthogonal Wavelengths Selection as a new method for multivariate calibration in spectroscopy
(Elsevier Science, 2019-03)
Wavelength selection is a critical step in multivariate calibration. Variable selection methods are used to find the most relevant variables, leading to improved prediction accuracy, while simplifying both the built models ...
Total anthocyanin content in intact açaí (euterpe oleracea mart.) and juçara (euterpe edulis mart.) fruit predicted by near infrared spectroscopy
(2015-01-01)
Açaı (Euterpe oleraceae Mart.) and jucxara (Euterpe edulis Mart.) palms are native to Brazil and these species are rich in anthocynanins. The methods applied to determine anthocyanins are time-consuming, generate chemical ...
Easy estimation of endoglucanase activity using a free software app for mobile devices
(2020-01-01)
This study describes the estimation of the enzymatic activity of endoglucanase based on the 3,5-dinitrosalicylic acid (DNS) method and carboxymethylcellulose (CMC) substrate using glucose as the analyte. As an alternative ...
