We show from one-loop quantum gravity and statistical thermodynamics that the thermodynamics of quantum foam in flat space-time and Schwarzschild space-time is exactly the same as that of Hawking-Unruh radiation in thermal equilibrium. This means we show unambiguously that Hawking-Unruh thermal radiation should contain thermal gravitons or the contribution of quantum space-time foam. As a by-pr...

A generalized version of the TROSY experiment allows the spin-state selective editing of the four multiplet components of N–H cross peaks of amide groups in proteins into four different subspectra, with no penalty in sensitivity. An improvement by Î2 in sensitivity results, if only two of the four multiplet components are selected. Use of the experiment for the measurement of JHN coupling const...

Introduction. In the present paper a new invariant quadratic differential form Û is geometrically defined for a general pair of surfaces S> S' whose corresponding points x, x' determine the metric normal to S a t x. The ratio of the form Q to the first fundamental form ds of 5, in which Î2 and ds are defined for a common arc element of S at x, is found to be independent of the direction of the ...

Introduction Advancements in medicine demand less invasive therapies and faster recovery times for large-area skin damage caused by burns, large ulcers and tumours. To cover the wound and aid in the recovery process platelet-rich plasma is often used as adjuvant for skin grafting. Platelet-rich plasma is a growth factor–enriched with platelet concentrate–and is obtained from whole autologous bl...
