The influence of external field on the lubricity of mineral oil for railway transport
MATEC Web of Conferences, 2017 The use of mineral oil is associated with its gradual operational degradation caused by its natural aging and contamination with various impurities. As the concentration of impurities increases, the number of active surface molecules which determine the ...

Detection of high-speed railway subsidence and geometry irregularity using terrestrial laser scanning [PDF]
, 2014 Subsidence and geometry deformation monitoring are essential for safe transportation on a high-speed railway. Terrestrial laser scanning (TLS) is able to collect dense three-dimensional point data from the survey scene and achieve highly accurate ...

American Journal of Industrial Medicine, EarlyView.ABSTRACT Background Mining workers are exposed to a range of respiratory hazards, including respirable dust. While exposure to respirable crystalline silica in the mining industry has been found to be common, less is known about trends in measured levels of exposure to respirable dust overall.

The Insistence of Blackness and the Persistence of Antiblackness in Ireland
Australian Journal of Social Issues, EarlyView.ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

Biochemistry and Molecular Biology Education, EarlyView.ABSTRACT Gamification is characterized by the use of gaming elements in a non‐gaming context. This concept is commonly applied in teaching to create a more meaningful and activating learning environment. The major aim of this study was to compare possible effects of gamification on a traditional interactive teaching concept in a biochemistry course on ...
