VISCOSITY COEFFICIENTS OF THE A-PHASE OF SUPERFLUID He AT LOW TEMPERATURES

It has been shown that the Boltzmann equation for the viscosity of the A-phase of superfluid 3He at low temperatures has the same form as for a normal Ferrni liquid. The viscosity coefficients A, B, C, D and E are derived exactly. The h , parameter plays an important role in determining the temperature dependence of the viscosity coefficients

Patient Complaints Emphasize Non-Technical Aspects of Care at a Tertiary Referral Hospital

Background:Patient concerns represent opportunities for improvement in orthopaedic care. Thisstudy’s objectiveis to identify the nature and prevalence of unsolicited patient complaints regarding orthopaedic care ata tertiary referral hospital. The primary null hypothesis that there are no demographic factors associatedwith complaint types was tested. Secondarily we determined if the overall com...

The Hydration Products of a Refractory Calcium Aluminate Cement at Low Temperatures

Calcium aluminates (CA) are the most important hydraulically setting cements used for preparing refractory castables, because they develop high strength at very early ages after placements.  The anhydrous phases of this kind of cements are CA, CA2 and traces of C12A7 and alpha-alumina. The major hydraulic phase in all of the CA cements including ciment fondu...
