Pigment identification of prehispanic ceramics during Inka occupation (Catamarca, Argentina) using non-invasive spectroscopy (Infrared-Raman)
(Elsevier Science, 2021-11)
The Hualfin Valley presents a long occupation period from the first agropastoralist societies (BC 200) to the Inka occupation (AD 1400). Ceramic production has played a fundamental role, being an important indicator of ...
Determination of oleic acid in sunflower seeds by infrared spectroscopy and multivariate calibration method
(Elsevier Science, 2009-12)
A method for the determination of oleic acid in sunflower seeds is proposed. One hundred samples of sunflower seeds were analyzed by near-infrared diffuse reflectance spectroscopy (NIRDRS). The direct measures were realized ...
A Novel approach to measure the total antioxidant power of wines through near infrared spectroscopy and its relevance in human nutrition
(David Publishing Company, 2019-06)
Abstract: Wine is the product of the alcoholic fermentation of the grape (Vitis vinifera). As such, it is a hydroalcoholic solution with a variable content of nutritional and functional (polyphenols) molecules, the latter ...
Molecular view by Fourier transform infrared spectroscopy of the relationship between lactocin 705 and membranes: Speculations on antimicrobial mechanism
(American Society for Microbiology, 2007-01-20)
Lactocin 705 is a bacteriocin whose activity depends upon the complementation of two peptides, termed Lac705α and Lac705β. Neither Lac705α nor Lac705β displayed bacteriocin activity by itself when the growth of sensitive ...

Influence of steroids on hydrogen bonds in membranes assessed by near infrared spectroscopy
(Elsevier Science, 2021-04-01)
The covalent O[sbnd]H bonds of water vibrate and absorb radiation in the near infrared (NIR) region at wavelengths that vary according to the strength of the bonds which, at the same time, are sensitive to the number and/or ...
A new and efficient variable selection algorithm based on ant colony optimization. Applications to near infrared spectroscopy/partial least-squares analysis
(Elsevier Science, 2011-08)
A new variable selection algorithm is described, based on ant colony optimization (ACO). The algorithm aim is to choose, from a large number of available spectral wavelengths, those relevant to the estimation of analyte ...
