The wear resistance research of the rail contact surface depending on the grinding process
Mechanics and Advanced Technologies, 2019 Background. Continuous mechanical loads on the rails during its contact with the wheel lead to an accumulation of residual stresses in the surface layers of the rails, resulting in fast-growing fatigue cracks.

steel research international, EarlyView.Strain‐induced NbC precipitation governs hot‐deformation resistance in CrNiMnMoB ultrahigh‐strength steel by suppressing dynamic recrystallization, increasing activation energy, and refining martensitic substructures. The precipitation response is controlled by temperature, supersaturation, and strain rate, with slow deformation promoting extensive NbC

“Tragic,” “Torment,” and “Torture”: Leadership as Fertile Ground for Women's Organizational Misogyny
Gender, Work &Organization, Volume 33, Issue 6, Page 2519-2543, November 2026.ABSTRACT This feminist study explores women's hostilities toward women in UK leadership as organizational misogyny. Organizations are mostly silent about misogyny, and gender studies have yet to empirically interrogate organizational misogyny and expose it as a critical method of women's oppression. Here, we explore women's organizational misogyny (WOM)

ANALYSIS OF PRESSURE FLUCTUATION BEHAVIOR DURING THE RAIL GRINDING PROCESS
Jixie qiangdu, 2016 There is some grinding pressure fluctuation on the rail grinding train operation,which affects the uneven surface of grinding rail. The dynamic model of rail grinding vehicle was established which gave full consideration to the grinding mechanism’s ...

‘There Has Been a Scandal’: Cultural Performers and the Strangers’ Churches of London
Renaissance Studies, Volume 40, Issue 5, Page 807-817, November 2026.ABSTRACT Despite what one might assume to have been a rigid line between London's refugee community—with its strict brand of Protestantism—and the city's performance cultures—often the target of strict Protestants' ire—historical records reveal a number of overlaps between those domains.

IMPROVING THE QUALITY OF MECHANICAL PROCESSING OF RAIL RAILS BY GRIND PROCESS
Collected scientific works of Ukrainian State University of Railway Transport, 2017 В статье рассмотрен процесс восстановления геометрии железнодорожного рельсового полотна посредством шлифования. Отмечено, что периодическая корректировка профиля головки рельса шлифованием позволяет обеспечить наилучший контакт колеса с рельсом и тем самым продлить его эксплуатационный ресурс до 20 %.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT A synergistic strategy combining a Ti interlayer and circular beam oscillation was proposed to improve the laser weldability of 6082‐T6 aluminum alloy. The Ti interlayer suppressed porosity, eliminated columnar grains, and significantly reduced grain size by 67.7% at the weld center. Mechanistically, fine L12‐Al3Ti precipitates clearly showing
