A new method for the determination of the size distribution of magnetic carrier systems, as well as for the proof of successful immobilization of biomolecules to magnetic particles was developed and ...tested. The method is based on the Forced Rayleigh Scattering (FRS) experiment, in which a diffraction concentration grating is created in a thin sample of colloidal fluid due to the absorption of an optical interference field.
The structuralization of the colloidal particles concentration in illuminated magnetic fluids with negative Soret constant was investigated. A theoretical explanation of the phenomenon, based on the ...study of the thermodiffusion process in colloidal fluids, was made. The development of the structuralization after the intensity of the illumination reaches some critical value was both simulated and observed experimentally.

An overview of results from the CERN experiment NA49 is presented with emphasis on most recent measurements. NA49 has systematically studied the dependence of hadron production on energy and system ...size or centrality. At top-SPS energy the detailed investigation of hadron production, now also extending to elliptic flow of Λ-baryons and to identified particle yields at high
