the potential of near infrared reflectance spectroscopy (nirs) as a fast method to predict the crude protein (cp) and moisture (m) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on partial least squares (pls) was evaluated. the coefficient of determination in calibration (r2c) and standard error of calibration (sec) were 0.95 and 1...

near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...

The potential of Near Infrared Reflectance Spectroscopy (NIRS) as a fast method to predict the Crude Protein (CP) and Moisture (M) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on Partial Least Squares (PLS) was evaluated. The coefficient of determination in calibration (R2C) and Standard Error of Calibra...

Near infrared reflectance spectroscopy (NIRS) was used to predict six biological properties of soil and earthworm casts including extracellular soil enzymes, microbial carbon, potential nitrification

Chemical assessments of forage clearly determine the forage quality; however, traditional methods of analysis are somehow time consuming, costly, and technically demanding. Near Infrared Reflectance Spectroscopy (NIRS) has been reported as a method for evaluating chemical composition of agriculture products, food, and forage and has several advantages over chemical analyses such as conducting c...

Determination of forage quality of available species is one of the fundamentalfactors for the management of rangelands. Near-Infrared Reflectance Spectroscopy (NIRS)was used to analysis the Nitrogen (N), Acid Detergent Fiber (ADF), Dry MatterDigestibility (DMD) and Metabolizable Energy (ME) content of three phenological stages(vegetative, flowering and seeding) of Bromus tomentellus samples in ...

Rapid and nondestructive methods such as diffuse reflectance infrared spectroscopy provide potentially useful alternatives to time-consuming chemical methods of soil metal analysis. To assess the utility of near-infrared reflectance spectroscopy (NIRS) and diffuse mid-infrared reflectance spectroscopy (DRIFTS) for soil metal determination, 70 soil samples from the metal mining region of Tarnows...
