Dynamic effect on turnouts of cars having wheelsets with thin flanges

Вестник Научно-исследовательского института железнодорожного транспорта, 2020
Geometrical parameters of the “wheelset—rail track” system are mutually related. Currently, a very topical issue is the question of a possible adjustment of the regulatory framework in the “wheelset—rail track” system in order to take into account the ...

Guideway and turnout switch for the SupraTrans project

Journal of Physics: Conference Series, 2006
This paper will deliver insight into technology and physics of the levitation system for the SupraTrans project, a prototype of a superconducting transportation system. The technology used herein bases on the flux pinning in melt-textured bulk YBa2Cu3O7-X (YBCO) that stabilizes the lateral and the vertical position of the vehicle above the magnetic ...

Geometrical layouts of railroad switches applying single turnouts

Transportation Overview - Przeglad Komunikacyjny, 2017
In the article there were included issues of geometrical layouts of railroad switches “in design” by applying single turnouts which are components of technical research of turnouts. During rebuilding railroad switches it is required to project a new geometry by a correct selection of kinematic and geometrical parameters.

Dynamic Performance of Concrete Turnout Bearers and Sleepers in Railway Switches and Crossings [PDF]

Advances in Civil Engineering Materials, 2018
Abstract With constant changes of their geometry and alignment, wheel–rail forces, and track and operational parameters, railway infrastructures are exposed to nonlinear actions by nature. A detrimental type of loading condition that causes cracking in the railway concrete bearers in switches and crossings is the dynamic transient wheel ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Safety and Tolerability of Givinostat: Evidence From Real‐World and Clinical Practice

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The aim of our study was to establish the prevalence of adverse events in a real‐world setting in boys living with Duchenne muscular dystrophy (DMD) treated with givinostat as part of an Expanded Access Program (EAP) in Italy. Methods The cohort included 90 ambulant boys, with age when treatment started between 6 and 23 years (mean ...

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

Advanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
