This paper aims at exploring the potential of visible and near infrared (vis-NIR) spectroscopy for on-line measurement of soil pH, with the intention to produce variable rate lime recommendation maps. An on-line vis-NIR soil sensor set up to a frame was used in this study. Lime application maps, based on pH predicted by vis-NIR techniques, were compared with maps based on traditional lab-measur...

RATIONALE AND OBJECTIVES Near-infrared (NIR) diffuse optical spectroscopy and imaging may enhance existing technologies for breast cancer screening, diagnosis, and treatment. NIR techniques are based on sensitive, quantitative measurements of functional contrast between healthy and diseased tissue. In this study, the authors quantified the origins of this contrast in healthy breasts. MATERIAL...

A tetrasubstituted tetraferrocenylstannane is formed from 1-bromoferrocene-1'-carboxylic acid methyl ester and copper bronze. The molecular structure is almost perfectly tetrahedral with FeFe distances of around 6 A. In solution two sequential one-electron processes and one two-electron process are indicative of mixed-valent intermediates. Intermetallic interactions have been probed by preparat...

OBJECTIVE A method for rapid analysis of the refining process of honey was developed based on near-infrared (NIR) spectroscopy. METHODS Partial least square calibration models were built for the four components after the selection of the optimal spectral pretreatment method and latent factors. RESULTS The models covered the samples of different temperatures and time points, therefore the mo...

There are several methods in assessing the traits of rice including destructive and non-destructive method. The objective of this study is to evaluate the amylose content (AC) on seven types of rice grain in Malaysia market by using the Near-Infrared (NIR) Spectroscopy. AC is one of the main criteria to determine cooked rice quality. Total of samples are 210, there are including two types of br...

Blumea balsamifera (Ai-na-xiang) is used as an important plant source of natural borneol, which is widely used in the pharmaceutical industry. The aim of this study was to establish the methods based on near infrared (NIR) spectroscopy for determining the geographical origin of B. balsamifera, as well as developing a method for the quantitative rapid analysis of the active pharmaceutical ingred...
