Infrared Absorption Spectra of Steroids (an Atlas)
comments (p. 82), "Apr's de publications initiales optimistes, ont succede des rapports negatifs." In the introduction, it becomes clear that French laboratory methods are much like ours. The Lee-White method and the Quick test are standard procedures. On the other hand, the Continental workers seem to place more emphasis than we do on the in vitro heparin tolerance. Later portions of the book ...
متن کاملThe Effects of Erythema on Near-Infrared Absorption Spectra
The accute effets of sun-bathing on the near-infrared absorption spectra of skin was studied by exposuring the shoulders of a male volunteer to bright Finnish midsummer midday sun and measuring the spectra before and after the exposure and on several days after the exposure. Several spectra processing and classification methods were applied on the data set to find the differences caused by the ...
متن کاملInfrared absorption spectra of vinyl radicals isolated in solid Ne.
Irradiation of samples of solid Ne near 3.0 K containing ethene (C(2)H(4)) with vacuum ultraviolet radiation at 120 nm from synchrotron yielded new spectral lines at 3141.0, 2953.6, 2911.5, 1357.4, 677.1, 895.3, and 857.0 cm(-1). These features are assigned to alpha-CH stretching (nu(1)), CH(2) antisymmetric stretching (nu(2)), CH(2) symmetric stretching (nu(3)), CH(2)-bending (nu(5)), HCCH cis...
متن کاملNear-Infrared Absorption and Scattering Spectra of Tissues in Vivo
Tissue inhomogeneity is often neglected in the analysis of the spectral data collected in tissues. We have measured the absorption and reduced scattering spectra of the human forearm in the wavelength range 633-841 nm, and in the range of source-detector separations 0.7-3.3 cm. We found that the layered tissue structure due to the skin and adipose layers may have a significant effect not only o...
متن کاملSoft Soil Seismic Design Spectra Including Soil-structure Interaction
Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...
