The estimation of nitrogen status, non-destructively, in oilseed rape was performed using spectral reflectance with visible and near infrared reflectance spectroscopy (Vis/NIRS), and SPAD values of the oilseed rape leaves of 30 plots were measured by a SPAD 502 chlorophyll meter, and the research was carried out at experiment field in the Zhejiang University during growing season from 2007 to 2...

Near Infrared Reflectance Spectroscopy (NIRS), coupled with fiber optic probes, has been shown to be a quick and reliable analytical tool for quality assurance and quality control in the pharmaceutical industry, both for verifications of raw materials and quantification of the active ingredients in final products. In this paper, a typical pharmaceutical product, hydrocortisone sodium succinate,...

Ethanol-soluble carbohydrates (ESCs) of cool-season grasses include mono- and disaccharides sometimes short-chain fructans, which may exacerbate the risk pasture-associated laminitis. A calibration for prediction ESC concentrations by near-infrared reflectance spectroscopy (NIRS) was developed from 323 samples four grass species (orchardgrass, Kentucky bluegrass, tall fescue, perennial ryegrass...
