Community dynamics of lignicolous lichens on standing deadwood in a 275‐year chronosequence
Oikos, Volume 2026, Issue 6, June 2026.Dead trees provide discrete habitat patches in which patch quality changes gradually due to wood decomposition. Although in most cases these patches persist for not more than a few decades, in some ecosystems deadwood decomposition and the consequent change in habitat patch quality can be a centuries‐long process, potentially leading to dynamics of ...

Wear impact on rolling contact fatigue crack growth in rails
, 2012 Wear and rolling contact fatigue of rails are major problems for the railway industry and it is of high value to develop models for prediction of rail life.In this paper, a 2D FE model is used to simulate crack growth of a single head check--like RCF ...

Past Carbon Emissions and Future Targets for the Olympic Games
The Geographical Journal, Volume 192, Issue 2, June 2026.Short Abstract The global visibility and political weight of the Olympic Games can inspire climate change action. Yet, at the same time, the Olympics are also significant carbon emitters. To date, however, there is a lack of a systematic assessment of past carbon emissions and extrapolation of future targets considering international agreements.

Field Theory and Colonialism: Indirect Colonial Situation as a Social Field in Egypt (1882–1922)
Sociology Lens, Volume 39, Issue 2, Page 180-189, June 2026.ABSTRACT This paper argues that Egypt under British rule (1882–1922) constituted a field of power in which the local state of Egypt and the British administration competed to dominate three key subfields to ensure control over a contested territory: the modern courts system, policing, and agricultural production.
