Curriculum guidelines for the development of student agency in secondary education: A systematic review

The Curriculum Journal, EarlyView.
Abstract To prepare students for lifelong learning, and their role in society, student agency has been foregrounded as an important aim of secondary education. In general, student agency is seen as the will and skill to intentionally transform one's functioning or circumstances.

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

The Depositional Record, EarlyView.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...

Study on the diffusion and migration law of CO2 sequestrated in abandoned coal mine goaf

Deep Underground Science and Engineering, EarlyView.
The goaf of an abandoned coal mine, endowed with expansive fracture spaces and an abundance of residual coal, can be capable of sequestrating substantial quantities of CO2. The residual coal is the principal medium for the sequestration of CO2 in the form of adsorption and the amount of sequestration is considerable.

Strain‐based modeling and analysis for rock blasting and geomechanics applications

Deep Underground Science and Engineering, EarlyView.
This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.

Tri‐axial compressive behavior of high‐water material for deep underground spaces

Deep Underground Science and Engineering, EarlyView.
The relationship between the mechanical behavior and microstructures of the laterally confined high‐water material associated with water bleeding was established. Abstract Attributed to its superior water‐to‐solid ratio and quick setting time, the high‐water material is widely adopted in underground spaces as a cost‐effective and environmentally ...

Study on the Mining Pressure Law of Tunneling Roadway in Coal Pillar of Lower Coal Seam in the Mining Hollow Area

Energy Science &Engineering, EarlyView.
ABSTRACT In the downward mining, the goaf of the upper coal seam and the remaining coal pillars will have a negative impact on the stability of the lower coal seam roadway. If the roadway is excavated in the lower coal seam coal pillar, it is more likely to produce mutual superposition effects, which greatly increases the difficulty of roadway ...

Research on Grouted Steel Pipe Supports Roof Cutting and Gob‐Side Entry Retaining Support Technology for Fully‐Mechanized Caving Face

Energy Science &Engineering, EarlyView.
ABSTRACT Aiming at the roof control challenges of gob‐side entry retaining in fully mechanized top‐coal caving faces, traditional concrete‐filled steel tube (CFST) support technology exhibits limitations such as slow strength development and complex construction equipment.

Decentralized Wind Energy Systems as Catalysts for Urban Resilience: A Design Framework

Energy Science &Engineering, EarlyView.
ABSTRACT Confronting the escalating extreme weather events (EWEs) and intensifying winds, this study proposes an active response to these issues by exploring decentralized wind energy production for Peng Chau Island, Hong Kong. It integrates theoretical perspectives on energy democracy—empowering local communities through energy autonomy—and urban ...
