Impact of wheel shape on the vertical damage of cast crossing panels in turnouts [PDF]

, 2015
Impact forces generated in the load transfer area of railway crossing panels lead to a range of degradation modes from wear and fatigue of the contacting materials, fatigue of supporting components to ballast/subgrade deterioration.

Challenges to Attaining the SDG 2 (Zero Hunger) and Future Projections: The Criticality of Types of Corruption, Human Rights, and Greenhouse Gas Emissions for Selected Asian Countries

Sustainable Development, EarlyView.
ABSTRACT By the mid‐21st century, the global economic system had not yet fully solved the problem of hunger. Therefore, achieving SDG 2 (Zero Hunger), one of the UN's Sustainable Development Goals (SDGs), is crucial. This study therefore aims to examine the factors that may lead to hunger in seven selected Asian countries (Afghanistan, Bangladesh ...

A Global Systematic Review and Meta‐Analysis of Landowners' Participation in Forest Carbon Markets

Sustainable Development, EarlyView.
ABSTRACT Forest carbon markets contribute to achieving Sustainable Development Goals and national mitigation plans. Identifying the factors associated with landowner participation in forest carbon projects is essential for effective project design. We conduct a systematic review and meta‐analysis to synthesise participation factors, determine mean ...

Forest and fire drive moose (deníe) detections near their northern range limit

Wildlife Biology, EarlyView.
One way to understand species range shifts in response to anthropogenic climate change is to study populations living at the limit of climate and resource suitability. Moose Alces alces (deníe in Dënesųłıné) generally require forest–wetland landscape complexes but are increasingly seen across the forest–tundra transition at their northern range limit ...

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

GHOSTLY ENCOUNTERS IN LAGOS: Virtual Reality between Urban Marketing and Media Activism

International Journal of Urban and Regional Research, EarlyView.
Abstract This article examines the role of virtual reality (VR) technologies in mediating and contesting dominant visions of urban futures in West Africa. Drawing on theoretical insights from a hybridization of the work of the German‐born Jewish critic Walter Benjamin and the Nigerian writer Amos Tutuola, I introduce the concept of phantasmagoria as a ...

Evolutionary Mechanisms of Coagulation Factors in Cetaceans During Aquatic Adaptation

Integrative Zoology, EarlyView.
Compared with Bos taurus, T. truncatus showed shorter prothrombin time and thrombin time but prolonged activated partial thromboplastin time, indicating pathway‐specific remodeling of coagulation. Evolutionary analyses identified 18 positively selected genes and accelerated F11 evolution, while functional assays revealed increased coagulation factor ...

Research on a Simplified Estimation Method for Wheel Rolling Resistance on Unpaved Runways

Applied Sciences
Aiming at the practical difficulties (e.g., high cost of full-scale tests) in testing the rolling resistance of aircraft wheels on unpaved runways, this study establishes a theoretical calculation formula for wheel rolling resistance based on the Bekker ...
