An evolution of low-field strength MRI [PDF]

open access: yesMagnetic Resonance Materials in Physics, Biology and Medicine, 2023
AbstractThe paper describes the evolution of low-field MRI from the very early pioneering days in the late 70 s until today. It is not meant to give a comprehensive historical account of the development of MRI, but rather to highlight the different research environments then and now.

Acute and delayed effects of a resistance training session leading to muscular failure on mechanical, metabolic, and perceptual responses [PDF]

open access: yes, 2018
This study explored the acute and delayed (24 and 48 hours after exercise) effects of a resistance training session leading to muscular failure. Eleven resistance-trained men completed a training session consisting on 3 sets of repetitions to failure ...

Experimental studies of scale effects on shear strength, and deformation of rock joints [PDF]

open access: yes, 1980
The effect of scale on shear strength is studied by performing direct shear tests on different sized samples of large joints. A rubber moulding system is used to obtain impressions of the roughness from a variety of natural joint surfaces.

Homogenization methods and macro-strength of composites [PDF]

open access: yes, 2002
A multi-phase periodic composite subjected to inhomogeneous shrinkage or temperature deformation and prescribed mechanical loads is considered. The asymptotic homogenisation is applied for calculation of homogenized macrostresses. A non-local approximate

Constant field strengths on T2n [PDF]

open access: yesNuclear Physics B, 2000
We analyse field strength configurations in U(N) Yang-Mills theory on T^{2n} that are diagonal and constant, extending early work of Van Baal on T^4. The spectrum of fluctuations is determined and the eigenfunctions are given explicitly in terms of theta functions on tori. We show the relevance of the analysis to higher dimensional D-branes and discuss
