Thermal conductivity of high- T c superconductors

This paper reviews existing data on the thermal conductivity of high- T c superconductors. Included are discussions of pristine polycrystalline high- T c ceramics, single crystal specimens, and high- T c materials structurally modified by substitution or by radiation damage. The thermal conductivity of high- T c superconductors is compared with that of conventional superconductors, and dramatic differences are found between the two families. Mechanisms of thermal conductivity applicable to high- T c perovskites are discussed and implications for theories of high- T c superconductivity are noted.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45121/1/10948_2004_Article_BF00617463.pd

Prominent lobule correction in otoplasty: With step-by-step description of the “y to v setback” technique

One of the most common long-term complications of the operation is an unnatural “operated” look of the ear. Our current aim in otoplasty must be further refinement of the surgical technique in order to address finer details such as Stahl’s ear, prominent Darwin’s tubercle, and lobule prominence. Some surgeons prefer skin excisions and others suggest correction of cartilage framework for correction of the lobule deformity. The authors preferred technique is Y to V setback of the lobule. It may be used as the last step of a routine otoplasty operation or for correction of isolated or secondary prominent lobule deformities. The technique is described. © Springer-Verlag Berlin Heidelberg 2013
