The critical-current density of grain boundaries in high-T/sub c/ superconductors was enhanced to values exceeding the previously known limits both at 4.2 K and at 77 K. Noting the importance of space-charge layers and of the d(x/sup 2/-y/sup 2/)-wav

The superconducting and normal-conducting transport properties of interfaces play an important role for numerous applications of high-Tc superconductors. For basic reasons, the physics of interfaces in high-Tc superconductors is considerably richer a

With the discovery of high-temperature superconductivity1, it seemed that the vision of superconducting power cables operating at the boiling point of liquid nitrogen (77 K) was close to realization. But it was soon found that the critical current de

The effects of stand establishment and nitrogen fertilizer on yield and yield stability of winter oil-seed rape (Brassica napus L.) were investigated in two field experiments in north eastern Germany (Mecklenburg-Vorpommern). During six years of test
