Milk urea analytical result reliability and its methodical possibilities in the Czech Republic

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013
Control of milk urea concentration (MUC) can be used in diagnosis of the energy–nitrogen metabolism of cows. There are more analytical methods for MUC estimation and there are also discussions about their result reliability.

Infrared photometry and spectrophotometry of Titan [PDF]

The wide variation in infrared brightness temperature of Titan is explained in terms of a greenhouse effect. Radiometric observations in the infrared and microwave frequencies indicate an alternate hot atmospheric model. Methane, ammonia, hydrogen atoms,

Molecular Signatures in the Near Infrared Dayside Spectrum of HD 189733b [PDF]

, 2008
We have measured the dayside spectrum of HD 189733b between 1.5 and 2.5 microns using the NICMOS instrument on the Hubble Space Telescope. The emergent spectrum contains significant modulation, which we attribute to the presence of molecular bands seen ...
