Back-bending

Lie on a large inflatable ball and do modified back bends. 

In severe forms of alcoholic liver disease, bed rest, either in strict or semistrict form, is called for. Once the disease has reached a phase in which muscular activity seems to be desirable, non-strenuous sport, gymnastics or swimming might be helpful. Physical exercises that can easily be carried out at home have proved successful in such cases (and also in latent HE) 2 or 3 times a day 10 to 15 slow knee-bends, 10 to 15 toe-stands, 10 to 15 arm-bends, and 10 to 15 back-bends, so that some 60% of the musculature are regularly used.

In a number of publications [12], classification of phase transitions in small systems has been presented. This scheme is based on the distribution of zeroes of the canonical partition function in the complex temperature plane. Among others. Gross has suggested a microcanonical treatment [13], where phase transitions of different order are distinguished by the curvature of the entropy 5 = In According to this scheme, a back-bending in the micro-... 

Indeed, f is found first to increase with t, but from a certain value on it decreases and would finally even become negative. Note that this would reverse the drift direction in electrophoresis measurements. While nonlinear and linearized PB theory coincide with the data and with each other for small Manning parameter, they completely fail to predict the back-bending, which already sets in at comparatively small values of t Hypemetted chain... 

Dendrimers are without doubt a unique case of 3D macromolecules. In this class, PPDs stand out because of the rigidity of the dendrons, which excludes back-bending. This leads to a pronounced rigidity of the shape, which can be further controlled by choice of the core and the branching points. 

The back-bending effect, i.e., the drastic change of the moment of inertia (at about I s 16h for some rare-earth nuclei) was first observed experimentally by Johnson et al. (1971). The explanation of the effect, on the basis of sudden nucleon angular momentum alignment, was given by Stephens and Simon (1972).
