The Effects of Soil Moisture Content on Reflectance Spectra of Soils Using UV-VIS-NIR Spectroscopy
This study was conducted to investigate the effects of soil moisture content on reflectance spectra of sandy soils with different phosphorus (P) concentrations using UV-VIS-NIR reflectance spectroscopy. Sandy soils with average particle size of 250 μm were used. Investigations were conducted at 0, 12.5, 62.5, 175, 375, 750, and 1000 mg/kg phosphorus application rates. Three soil moisture conten...
متن کاملQuantitative assessment of skin layers absorption and skin reflectance spectra simulation in the visible and near-infrared spectral regions.
We have simulated diffuse reflectance spectra of skin by assuming a wavelength-independent scattering coefficient for the different skin tissues and using the known wavelength dependence of the absorption coefficient of oxy- and deoxyhaemoglobin and water. A stochastic Monte Carlo method is used to convert the wavelength-dependent absorption coefficient and wavelength-independent scattering coe...
متن کاملAnalysis of visible reflectance spectra of stored, cooked and diseased chicken meats.
Visible spectra of cold stored, cooked, and diseased chicken meats were collected. Changes in ratios of R(1)=A(485 nm)/A(560 nm) and R(2)=A(635 nm)/A(560 nm,) which are related to absorbances of the bands at 485 (metmyoglobin), 560 (oxymyoglobin), and 635 nm (sulfmyoglobin), were observed to be useful for studying the variation of meat color under the conditions of cold storage and cooking proc...
متن کاملLaboratory simulations of reflectance spectra
Reflectance spectra from the surface of Mars collected by instruments such as the imaging spectrometer (ISM) onboard the 1988 Soviet Phobos 2 spacecraft exhibit strong 3/•rn absorption features that have long been attributed to hydrated materials on the Martian surface. This interpretation is consistent with a series of chemical weathering models suggesting an abundance of palagonites, clays, a...
متن کاملQuantitative spot-test analysis of metformin in pharmaceutical preparations using ultraviolet-visible diffuse reflectance spectroscopy.
A quantitative spot-test for the determination of metformin in pharmaceutical preparations using diffuse UV-visible reflectance is reported. The procedure is quite simple, involving in the formation of a metformin-nickel(II) complex on a glass filter membrane with a later measurement of the reflectance in the spectrophotometer using an integration sphere. The analytical results obtained with co...
