What drives animal responses to high severity fire? The role of functional traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

How Circular Innovation Is Learned: A Process Study of Modularity‐Based Initiatives in Industrial Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular innovation (CI) research has identified a wide range of circular strategies and design approaches, yet offers limited insight into how CI evolves as a learning process within firms and which governance mechanisms guide this progression. Drawing on organizational learning (OL), this study examines how exploration and exploitation shape

Research on Smoke Flow in a Tunnel Fire of Subway System [PDF]

open access: yes, 2014
A three-dimensional mathematical model of the smoke movement in tunnel fires was established. Finite volume method was used to discretize the governing equations and the SIMPLE algorithm was employed to solve the governing equations. A scaling model (1:8)

Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

open access: yesDeep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

Interaction of Segmental Tunnel Linings and Dip-Slip Faults—Tabriz Subway Tunnels

open access: yesApplied Sciences, 2023
In some subsurface urban development projects, bedrock faults intersecting with the tunnel path are inevitable. Due to the high costs of urban tunnel projects, it is necessary to study the behavior of such concrete structures under fault movement risks. Using an advanced 3D numerical finite difference code and a plastic hardening constitutive model for
