Near Infrared Reflectance Spectroscopy (NIRS) Determination of Isoflavone Contents for Selected Soybean Accessions [PDF]

open access: yes, 2012
Soybean isoflavones are of considerable interest in relation to their possible health effects in human diets. The rapid and economical determination of soybean isoflavone concentrations is essential for the investigation and development of soybean health

Application of Near Infrared Reflectance Spectroscopy to Predict Fecal Composition and Its Use for Digestibility Estimation [PDF]

open access: yes, 1996
Two experiments were carried out to investigate the applicability of near infrared reflectance spectroscopy (NIRS) to predict the chemical composition of feces. and thereby to estimate digestibility based on a lignin indicator method.

Rapid measurement of polycyclic aromatic hydrocarbon contamination in soils by visible and near-infrared spectroscopy [PDF]

open access: yes, 2013
Polycyclic aromatic hydrocarbons (PAHs) are widely distributed organic pollutants. At petroleum contaminated sites, PAHs are often the key risk drivers because of their carcinogenicity. Assessing the risk of PAH at contaminated sites by conventional soil

Assessing the amount of the anatase and rutile phases of TiO2 by optical reflectance measurements

open access: yesResults in Physics, 2021
The anatase (A) and rutile (R) phases of a series of titanium dioxide (TiO2) samples were investigated by optical diffuse reflectance spectroscopy. The samples consisted of commercial A and R high-purity TiO2 powders mixed together according to the Rmass/

Selection Models for the Internal Quality of Fruit, based on Time Domain Laser Reflectance Spectroscopy [PDF]

open access: yes, 2004
Time domain laser reflectance spectroscopy (TRS) was applied for the first time to evaluate internal fruit quality. This technique, known in medicine-related knowledge areas, has not been used before in agricultural or food research.

Prediction of Feed Digestibility Using Differences in NIRS Spectra between Feeds and Feces at a Determined Region of Wavelength [PDF]

open access: yes, 1998
A total of seventy-two pairs of feed and fecal samples collected from the digestion trials of dairy catlle were used in the study to predict dry matter digestibility (OMO).

Analysis of petroleum-contaminated soils by diffuse reflectance spectroscopy and sequential ultrasonic solvent extraction-gas chromatography [PDF]

open access: yes, 2014
In this study, we demonstrate that partial least-squares regression analysis with full cross-validation of spectral reflectance data estimates the amount of polycyclic aromatic hydrocarbons in petroleumcontaminated tropical rainforest soils.
