Analysis of Impact Hammer Rebound to Estimate Rock Drillability

, 2000
In this paper, the piston rebound common to both the Schmidt Impact Hammer and downhole hammer drills has been analyzed and calculated by means of stress wave theory and the energy conservation law.

Freedom dreaming of migrant justice: Critical reflections on counterspaces and institutional violence in the university

American Journal of Community Psychology, EarlyView.
Abstract US universities are built on stolen land and sustained through hierarchies of power that produce what migrant justice scholars name as b/order regimes. As institutions that claim to be sites of learning and inclusion, universities are fraught with contradictions as simultaneously sites of dispossession, exclusion, and control.

How Can Community Music Enhance Place‐Based Efforts to Create Greater Social Equity? Insights From an Australian Cultural Mapping Exercise

Australian Journal of Social Issues, EarlyView.
ABSTRACT Social inequity is increasing in Australia, often manifesting in entrenched locational disadvantage that requires place‐based responses grounded in local strengths, knowledge and participation. While community music programmes have demonstrated a range of positive social outcomes, their potential contribution to place‐based efforts addressing ...

Research on the Rebound Hammer Testing of High-Strength Concrete’s Compressive Strength in the Xinjiang Region

Buildings, 2023
Enhancing the assessment of compressive strength and the efficiency of rebound hammers in non-destructive testing for high-strength concrete is an urgent issue in construction engineering. This study involved C50 to C90 high-strength concrete specimens, utilizing rebound hammers with nominal energies of 4.5 J and 5.5 J, along with a compression machine.

Morphological plasticity in the dentition of the lungfish Gnathorhiza from the Permian of Brazil: A population‐level geometric morphometric analysis

The Anatomical Record, EarlyView.
Abstract Dental plates are pivotal in the lungfish paleontological record, constituting highly mineralized structures resilient to diagenetic processes. This study provides a detailed description and quantitative shape analysis of 95 newly discovered Gnathorhiza sp. dental plates from the Middle–Late Permian Corumbataí Formation, Brazil.

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

Archaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

Powerful transformations: The experiences of higher education teaching staff who were first‐generation university students

British Educational Research Journal, EarlyView.
Abstract Historically, a university education has been seen primarily as a route for the middle classes to achieve professional qualifications while structural barriers have served to restrict entry to individuals from particular demographics. First‐generation students (FGS), often with low socio‐economic backgrounds, face multiple barriers to Higher ...

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

Biological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Eco‐Innovation, Economic Complexity, and Sustainability: A Bibliometric and Systematic Literature Review

Business Strategy and the Environment, EarlyView.
ABSTRACT This study systematizes the literature on eco‐innovation and economic complexity, aiming to understand how the sophistication of productive structures shapes countries' capacity to develop environmentally responsible innovations, and how eco‐innovation may, in turn, influence productive sophistication.
