Magnetohydrodynamic properties of incompressible Meissner fluids
We consider a superconducting material that exists in the liquid state, more
precisely, in which the Meissner-Ochsenfeld effect persists in the liquid
state. First, we investigate how the shape of such a hypothetical Meissner
liquid will adapt to accomodate for an applied external field. In particular,
we analyse the case of a droplet of Meissner fluid, and compute the elongation
of the droplet and its quadrupole frequency as a function of the applied field.
Next, the influence of an applied field on the flow of the liquid is studied
for the case of a surface wave. We derive the dispersion relation for surface
waves on an incompressible Meissner fluid. We discuss some candidate
realizations of the Meissner fluids and for the case of a superconducting
colloid discuss which regime of wave lengths would be most affected by the
Meissner effect.Comment: 12 pages, 3 figure
Effect of preoperative single-dose corticosteroid administration on postoperative morbidity following esophagectomy.
Eight clinical trials involving the administration of preoperative i.v. methylprednisolone have been undertaken in order to decrease the considerable inflammatory response to esophageal resection, in an effort to decrease the supposedly associated morbidity and mortalityComparative StudyJournal ArticleMeta-AnalysisReviewSCOPUS: ar.jinfo:eu-repo/semantics/publishe
