Combination of dynamic and static light scattering experiments gives important information on structural and dynamic properties of polymer solutions and colloidal suspensions. However, the analysis of light scattering experiments in turbid media is highly complicated due to the presence of multiple scattering. Recently, a one-beam set-up has been proposed and it could be shown that the cross co...
Exclusive electroproduction of π + mesons was studied by scattering 27.6 GeV positrons or electrons off a gaseous hydrogen target. The spin-averaged cross section and the single-spin azimuthal asymmetry with respect to transverse target polarisation were measured as a function of the Man-delstam variable t, the Bjorken scaling variable x B , and the virtuality Q 2 of the exchanged photon. The r...
In this paper, we have discussed about the role of two emittance values suggested for Iranian Light Source Facility (ILSF) (3.278 and 0.476 nm.rad) on different radiation features of the synchrotron light sources (bending magnet, shaker and oscillator) such as spot size, divergence of the beam on light spot, brilliance and important quantities in beamline design such as photon cross-section, op...
This paper deals with the problem of non-uniform torsion in thin-walled elastic beams with asymmetric cross-section, removing the basic concept of a fixed center of twist, necessary in the Vlasov’s and Benscoter’s theories to obtain a warping stress field equivalent to zero. In this new torsion/flexure theory, despite of the classical ones, the warping function will punctually satisfy the first...
