Preliminary results on dynamic analysis of a new test rig for wheel-rail contact studies

A new reduced–scale test rig is developed owing to significantly contribute to the applicability of the laboratory tests on rolling contact fatigue (RCF) in wheel-rail material. This paper introduces the dynamic analysis of the test rig, in order to assess the vibration behaviour of the system with respect to contact phenomenon. Finite element modelling (FEM) is used to simulate the mecha...

Breaking butterflies on a wheel.

W ell it’s that time of the year again. As the southern hemisphere slowly warms to a new spring, so the annual Ig Nobel awards reappear. I have written about these previously, but to the uninitiated these awards embody the pinnacle of human achievement and represent eccentric and unusual research as an alternative to the ‘‘real’’ Nobel awards, which although awarded at the same time tend to be ...

Hair Shafts

L. Rudnicka et al. (eds.), Atlas of Trichoscopy, DOI 10.1007/978-1-4471-4486-1_2, © Springer-Verlag London 2012 Most hairs viewed on trichoscopy are normal terminal hairs that are more than 55 m m wide and are uniform in thickness and color [ 1, 2 ] . Hair shaft thickness may be roughly estimated with a handheld dermoscope (thin, normal, thick). Many videodermoscopes include software allowing a...
