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

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Commentary: Constructing Refugees in the Academic Discourse: The Hmong in America by Marc Dorpema [PDF]

Hmong Studies Journal, 2019
Produced in a historiographical spirit, this literature review traces trends in the depiction of Hmong Americansnot in popular representations such as newspapers or public perception, but in the American academic discourse itself.

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.

“From the Valley’s Embrace to the Land of 10,000 Lakes: Hmong Texts in the Diaspora” [PDF]

Hmong Studies Journal
Over the past five decades, the Hmong community in Minnesota has navigated displacement, adaptation, and culture preservation in various ways. One of the most profound aspects of this journey has been the role of language in shaping identity and ...

The Transition of Wat Tham Krabok Hmong Children to Saint Paul Public Schools: Perspectives of Teachers, Principals, and Hmong Parents [PDF]

Hmong Studies Journal, 2007
In 2004, with the closing of the last Hmong refugee camp, Wat Tham Krabok, the latest group of Hmong refugees resettled to the US. To facilitate the language transition of approximately 1,000 school-aged newcomer Hmong children, the Saint Paul Public ...

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Hmong Across Borders or Borders Across Hmong? Social and Political Influences Upon Hmong People: Keynote Speech by Dr. Prasit Leepreecha, at the Hmong Across Borders Conference [PDF]

Hmong Studies Journal, 2014
The Hmong are a transnational ethnic people, because of their dispersal from China into Southeast Asia in the early 19th century and from Southeast Asia to Western countries from 1975 onward.

Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

Deep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.
