Symmetric self-shrinkers for the fractional mean curvature flow [PDF]

, 2019
We show existence of homothetically shrinking solutions of the fractional mean curvature flow, whose boundary consists in a prescribed numbers of concentric spheres.

Concentric Black Rings

, 2004
We present new supersymmetric solutions of five-dimensional minimal supergravity that describe concentric black rings with an optional black hole at the common centre. Configurations of two black rings are found which have the same conserved charges as a

Effects of increasing isokinetic angular velocity on concentric and eccentric strength [PDF]

Journal of Men's Health
There is an inverse relationship between the ability to generate force during concentric muscle movements and the velocity of contraction. However, this relationship is not the same in eccentric muscle movements due to differences in mechanism ...

The relationship between functional capacity, muscle size and strength in chronic ACL deficient and ACL reconstructed individuals

South African Journal of Physiotherapy, 2000
Aim: The aim of this study was to assess the relationship between the quadriceps muscle atrophy and strength deficits caused by chronic ACL deficiency, and to ascertain whether these deficits were rectified in subjects who had undergone ACL ...

General Concentric Black Rings

, 2004
Supersymmetric black ring solutions of five dimensional supergravity coupled to an arbitrary number of vector multiplets are constructed. The solutions are asymptotically flat and describe configurations of concentric black rings which have regular ...

Baló’s concentric sclerosis

Journal of the Belgian Society of Radiology, 2014
Background: A 46-year-old woman was admitted with right-sided weakness, vertigo and nausea. Clinical examination revealed ataxia of the right limbs, diplopia and a counter-clockwise rotatory nystagmus. MRI of the brain was performed.

Mechanical thermal motor [PDF]

, 1976
An apparatus is described for converting thermal energy such as solar energy into mechanical motion for driving fluid pumps and similar equipment. The thermal motor comprises an inner concentric cylinder carried by a stationary core member.
