Cement Lines are Stiffer and Harder than Bone but Exhibit Different Mineral–Mechanics Relationships due to Thicker and Shorter Mineral Particles

open access: yesSmall Structures, EarlyView.
Bone's complex hierarchical structure contains many internal interfaces, including the cement line (CL) around osteons. This article shows that the CL is stiffer and harder than surrounding bone but has different mineral–mechanics relationships. These findings challenge the view of the CL as a soft, protective interface and provide insights for ...

Assessment of the factor κk,max in classification of steel fiber‐reinforced concrete

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a general approach, and results employed in a study aimed at assessing the value of a coefficient, κk,max, introduced in Annex L in EN 1992‐1‐1:2023 (EC2). This coefficient defines an upper limit of the ratio between steel fiber reinforced concrete (SFRC) characteristic and mean values of the residual tensile strengths, fR1

Separate and synergistic anti‐herbivore effects of non‐glandular trichomes and leaf chemistry in a desert plant

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant defence phenotypes commonly integrate physical and chemical traits that may act synergistically against herbivores, but empirical evidence for synergy as a defence strategy remains limited.

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

open access: yesJournal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Managing Capabilities for Achieving Net Zero via a Circular Economy: A Multilevel Framework

open access: yesBritish Journal of Management, EarlyView.
Abstract Corporate management faces increasing pressure to achieve both net‐zero and circular economy (CE) goals. As organizations rarely manage this alone, they must develop novel capabilities within themselves and across their value chains and ecosystems. To explore capability development for achieveing net zero via circularity, we adopt a multilevel
