The interaction between railway vehicle dynamics and track lateral alignment [PDF]

open access: yes, 2016
Track geometry deteriorates with traffic flow, thus it needs to be regularly restored using tamping or other method. As the deterioration is mainly in the vertical direction this aspect has been widely studied and models for its analysis developed ...

Forage Plant Host and Early Feeding Choices Affect Spodoptera litura Feeding, Development and Egg‐Laying

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We assessed Spodoptera litura (Lepidoptera: Noctuidae) performance on five common pasture plant species. Larvae consumed more dock, plantain and chicory per day than red or white clover, but with lower conversion efficiencies. Feeding on red clover reduced weights and egg laying, and lengthened development times compared with plantain.

Discrete elements method to model ballast behaviour under railway turnouts

open access: yesCogent Engineering
Ballast behaviour has a profound impact on global track performance and durability, particularly for turnouts where dynamic forces are substantial. As ballast is a discontinuous material, this paper proposes the application of a Discrete Element Method ...

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

open access: yesMarine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

A Critical Response to the UK's ‘Sullivan Review’ Into Sex and Gender in Research and Data

open access: yesTransactions of the Institute of British Geographers, EarlyView.
ABSTRACT This intervention argues that the UK Government‐commissioned independent review of data, statistics and research on sex and gender (the ‘Sullivan Review’) implicitly promotes the erasure of trans and gender diverse people from research and data collection protocols and carries worrying implications for the inclusion of trans people within UK ...
