Abstract

A new type of automatic force‐displacement recording myograph has been developed to measure the contraction–relaxation characteristics of contractile systems. The device produces a polytonic (variable‐force) load and therefore provides a more realistic measurement than either isometric or isotonic apparatus. Measurements on collagen that was first well ground and then extruded into a reconstituted thin tape show contraction and relaxation behaviour that can be characterized by a slightly modified form of Hill's 1938 equation. The characteristic parameters of the Hill equation determined for the reconstituted collagen were remarkably similar to those of intact muscle tissue.

Using density functional theory DFT , the multiplicity of the ground state was determined for Fe S Cl 1y ions as well as the order of the excited spin states. A 6 6 6 method to determine the exchange integrals J of the Fe S 5q cluster is presented based on 6 6 these results and a spin-coupling alge
