The lithic flints from Die "Chanqueyras" (Drôme). Technological and petrographic characterization of a lithic industry prechasséenne drômoise

, 2002
L'étude de la série lithique taillée du site de Die "Chanqueyras" (26) a consisté à caractériser cette industrie pré-chasséenne à partir d'une approche technologique et pétrographique. Les principales composantes de cette industrie qui compte au total 117 silex sont une option pour une production d'éclats lamellaires et ou de produits laminaires, un ...

The Influence of Responsible Leadership on Corporate Social Responsibility: The Mediating Role of Affective Organizational Commitment and Organizational Identification

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Currently, organizations are facing unprecedented stakeholder expectations for corporate social responsibility (CSR). To face this challenge, responsible leadership is crucial. However, the mechanisms that explain how these leaders encourage CSR engagement are underexplored, emerging as a critical research priority.

Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil

Deep Underground Science and Engineering, EarlyView.
Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

A review on rockburst prediction and prevention to shape an ontology‐based framework for better decision‐making for underground excavations

Deep Underground Science and Engineering, EarlyView.
A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming

Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

Deep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Modeling and experimental validation of bolt–grout bond–slip behavior for deep underground excavation support

Deep Underground Science and Engineering, EarlyView.
A novel shear‐lag model, validated by pull‐out tests, incorporates a constant bond stress stage to predict the complete load–displacement response of grouted rock bolts, providing a new tool for optimizing anchorage length and material toughness in deep underground engineering. Abstract The stability of rock masses in deep underground excavations, such
