There is a vast amount of new medical information published on diabetes each year; the number of systematic reviews on diabetes is also increasing rapidly. It is therefore difficult for clinicians keep up to date with the new evidence. It is suggeste

Root-restricting soil layers reduce crop yields in the southeastern U.S. almost every year due to temporary periods of drought. Subsoiling beneath these layers is an annual practice for most farmers in this region as a method of removing this barrier

The nonlinear relation between supercurrent and superfluid velocity:js(vs)=Ρsvs (1-(vs/vc)2/3)provides a coupling mechanism between the sound and Helmholtz modes of a short cylindrical cavity closed by a superleak at the centre of one end. Appropria

After a historical introduction to the discovery of vortex mutual friction in He II, the equivalent modern experiment on superfluid 3He is described and its interpretation discussed.

We give a full account of our extensive measurements of vortex mutual friction in rotating superfluid 3He, in both the A- and B-phases. The B-phase results are in qualitative agreement with a theory based on the concept of "spectral flow"; the agreem

The Universe contains much more matter than antimatter, which is probably the result of processes in the early Universe in which baryon number was not conserved. These processes may have occurred during the electroweak phase transition, when elementa

We have measured the resistive and reactive mutual friction coefficients in rotating superfluid ${}^{3}\mathrm{H}\mathrm{e}\ensuremath{-}A$ at $29.3\mathrm{bars}$ pressure. The results agree with those predicted from the equation of orbital hydrodyna

Group V transition metal nitride foils were fabricated in an ultrahigh vacuum chamber and superconducting transition temperature ( T c ), lattice parameter ( a 0 ), and electron energy loss (EELS) measurements were performed on these samples. It is f

We have investigated transverse continuous wave NMR in a geometry where the modes are influenced by susceptibility anisotropy. The helium sample is separated by mylar foils into layers 12 μm thick perpendicular to the external dc magnetic field. In

The equations decribing the spin dynamics of 3 He-A have been generalised to allow for the effect of susceptibility anisotropy on the Leggett-Takagi damping. Analytical and numerical solutions have been obtained for the configuration where1 is locked
