Basic quantities for symmetry adaptation are discussed in connection with molecular and solid state physics. This gives rise to a formalism whose central elements are operator equivalents adapted to a point group. Such symmetry adapted operator equivalents are defined in terms of Schwinger operators so...

The present work studies the characteristics of the ternary LiNO 3 + NaNO 3 + H 2 O system and of the associated binary solutions LiNO 3 + H 2 O and NaNO 3 + H 2 O, in the concentration range 1, 5-3 molal. The change of ion-ion and ion-solvant type interactions in ternary ...
The intensity of the Raman Effect is affected by the refractive index of the medium, thus the true intensity has to be corrected for 1 an optical effect 2 an internal field effect. The internal field effect correction is necessary when the scattering coefficient is obtained by means of the ...
For every cases, we rely on a procedural approach based on progressive deformation, and eventually, on-the-fly refinement of the geometry just before the rendering stage.doi:10.1016/j.respe.2011.03.029Rivera DíazRoberto Carlogrenoble

An important issue in autoimmune diseases mediated by T cells, such as experimental allergic encephalomyelitis (EAE), is the affinity of the disease-inducing determinants for MHC class II proteins. Tolerance, either due to clonal deletion or anergy induction, is thought to require high-affinity ...
Methods The study was performed in a cohort of rheumatologists who usually prescribe bone mineral density assessment according to HAS criteria (one or more criteria) for bone mineral density (BMD) measurement as defined by: (a): vertebral fracture; (b): non traumatic non vertebral fracture; (...
The activation energies for the addition of hydrogen chloride to conjugated double bonds of cis-2-, trans-4-hexadiene in ethanol or dichloroethane have been determined by rapid Raman spectroscopy as 71.1 ± 10.4 kJ mol1 and 36.8 ± 5.0 kJ mol1 respectively from plots of the intensity ratio I...
