Department of Civil and Environmental Engineering) ; Bickmore, Barry R. (Brigham Young University. Department of Geological Sciences) ; Filz, George M. (Virginia Tech. Department of Civil and Environmental Engineering) ; Madden, Andrew S. (University of Oklahoma. School of Geology and Geophysics)
The coefficient of friction of clay minerals at the micro-scale has generally not been studied due to difficulties in obtaining measurements in a bulk-soil volume undergoing shear at such small scales. [...]

The transportac loss Q in a superconducting cylinder of radius a with a power-law current-voltage characteristicE=Ec∣J/Jc∣n as a function of current amplitude Im is numerically calculated for a set of given values of a,Jc, and frequency f at n=5, 10, 20, and 30. [...]

4 p, 260.7 KB ac susceptibility and critical-current densities in sintered YBa2Cu3O7−δ superconductors / Chen, Du-Xing (Institució Catalana de Recerca i Estudis Avançats) ; Sánchez Moreno, Álvaro (Universitat Autònoma de Barcelona. Departament de Física) ; Pardo Vivé, Enric (Universitat Autònoma de Barcelona. Departament de Física) ; Bartolomé Porcar, María Elena (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
The field-amplitude and frequency dependent complex ac susceptibility of a well sinteredYBa2Cu3O7−δ disk has been measured at 77K, which shows that its intra- and intergranular critical-current densities are determined by the collective flux creep inside the grains and the maximum Josephsoncurrents across the grain boundaries, respectively. [...]
