Background: ATR-FTIR spectroscopy is proved to be a simple, reliable, rapid and easy-to-use technique assess the groundnut seed quality. Groundnut seeds are highly sensitive deterioration mainly due their chemical composition moisture content. The high oil content fatty acids of reduces viability well in advance lipid peroxidation process, which most frequent cause ageing. As result, not only p...

The physical processes that govern meltwater flow through snow are complex and spatially variable. Remote sensing studies may be a cost-effective approach for studying these variations, and may help to scale the knowledge obtained from field-scale observations and experiments. This paper focuses on the analysis of spatial variability of reflectance obtained from infrared photographs of a snow s...

Attenuated total reflectance-Fourier transform infrared spectrometry and chemometrics model was used for determination of physicochemical properties (pH, redox potential, free acidity, electrical conductivity, moisture, total soluble solids (TSS), ash, and HMF) in honey samples. The reference values of 189 honey samples of different botanical origin were determined using Association Official An...

We present results of mid-infrared λ = 5.0 − 16.5 µm spectrophotometric imaging of the starburst galaxies M 82, NGC 253, and NGC 1808 from the ISOCAM instrument on board the Infrared Space Observatory. The mid-infrared spectra of the three galaxies are very similar in terms of features present. The λ > ∼ 11 µm continuum attributed to very small dust grains (VSGs) exhibits a large spread in inte...

Two members of the glass-frog family Centrolenidae (Centrolenella fleischmanni, C. prosoblepon) and the hylid subfamily Phyllomedusinae (Agalychnis moreletii, Pachymedusa dacnicolor) reflect near-infrared light (700 to 900 nanometers) when examined by infrared color photography. Infrared reflectance may confer adaptive advantage to these arboreal frogs both in thermoregulation and infrared cryp...

The young massive stellar object G35.20-0.74 was observed in the mid-infrared using T-ReCS on Gemini South. Previous observations have shown that the near infrared emission has a fan-like morphology that is consistent with emission from the northern lobe of a bipolar radio jet known to be associated with this source. Mid-infrared observations presented in this paper show a monopolar jet-like mo...

We obtain valuable information on the angular and seasonal variability of surface reflectance using a hand-held spectrometer from a light aircraft. The data is used to test a procedure that allows us to estimate visible surface reflectance from the longer wavelength 2.1 _tm channel (mid-IR). Estimating or avoiding surface reflectance in the visible is a vital first step in most algorithms that ...
