Prediction of Lifespan of Railway Ballast Aggregate According to Mechanical Properties of it

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2017
As the railway lifespan is the main criterion for selection of the aggregate for ballast and for planning the maintenance of the railroad, it is important to define the relationship between the particle load resistant characteristics and a lifetime of ...

From products to smart solutions: A value‐creation approach

open access: yesEuropean Management Review, EarlyView.
Abstract Smart solutions comprise a synergy of products, services, software, connectivity, data, and intelligence. This study examines the evolution of a manufacturer into a smart solution provider, highlighting the role of value‐creation capabilities, activities, and practices. Through a longitudinal, in‐depth single‐case study of a leading technology

Resin recovery and the use of computed tomography for quantitative image analysis of railway ballast

open access: yes, 2014
Over its life cycle, railway ballast undergoes changes to its fabric structure due to train loading and maintenance (e.g. tamping). Understanding these changes and linking them quantitatively to the loading regime has the potential to inform improved ...

Adaptation to extreme environments: A review of Antarctic fish physiology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

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 ...

Reconstructing the major skull myology of the giant stem‐amphibian Mastodonsaurus: A case study for early tetrapods

open access: yesJournal of Anatomy, EarlyView.
We reconstruct the major cranial musculature of the giant stem amphibian Mastodonsaurus giganteus, revealing a differentiated jaw‐adductor system, a probable sesamoid pulley, and previously unrecognised muscles. This EPB‐based case study establishes an anatomical framework for modelling feeding in early tetrapods and supports interpretations of ...

Stress–Dilatancy For Crushed Latite Basalt

open access: yesStudia Geotechnica et Mechanica, 2018
In this article, the stress–dilatancy relationship for crushed latite basalt is analysed by using Frictional State Theory. The relationship is bilinear, and the parameters α and β determine these two straight lines.

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 ...

Gendered Harmony and Unsung Collections: Two Debussy Rabbit Holes

open access: yesMusic Analysis, EarlyView.
ABSTRACT This review article on Mark McFarland's The Musical Relationship between Claude Debussy and Igor Stravinsky (2024) offers a critical reading of this recent text and treats its content as a springboard for the exploration of two issues untapped in existing musicological discourse.
