Dynamics of longitudinal and transverse fluctuations above TC in EuS
Using inelastic scattering of polarized neutrons near a finite Bragg reflection, the dynamics of longitudinal \ensuremath{\delta}S(q)\ensuremath{\parallel}q and transverse \ensuremath{\delta}S(q)\ensuremath{\perp}q spin fluctuations have been measured. The relaxation rates ${\mathrm{\ensuremath{\Gamma}}}_{\mathrm{\ensuremath{\alpha}}}$ follow rather precisely the dipolar dynamic-scaling function calculated recently by mode-coupling theory based on the Lorentzian approximation. The predicted longitudinal line shape near ${\mathit{T}}_{\mathit{C}}$ disagrees with our data.
Summary The objective of this investigation is to verify the deficiencies that incorporate both modelled and measured suspended sediment concentrations (SSC) data in a tidal dominated area. For this purpose a tidal channel, in the North Sea, was considered as the case study. The profiles of SSC from a model were compared with those from the field, in which some dissimilarity was observed. Intensive investigations were carried out to detect that the most discrepancies occur in shallow parts of the area and also during the low velocities. The origin of the shortcomings in regard with the modelling and measuring technique are discussed.
