Mechanism of Water Inrush Induced by Gob Water Under Repeated Mining and Control Technology Based on Roof Cutting Pressure Relief

To mitigate the threat posed by accumulated gob water to underlying coal seams during multi-seam mining, this study investigates the mechanism of water inrush induced by repeated mining and its control through roof cutting pressure relief.

Timely roof breaking and pressure relief technology by hard roof staged fracturing [PDF]

Hard roofs in longwall mining often generate large roof caving steps during initial weighting and form extended hanging roofs during periodic weighting. These phenomena can lead to sudden cave-ins, rock bursts, and mine seismicity.

Prediction of two-phase flow through a safety relief valve [PDF]

, 2013
Safety relief valves are necessary elements in any pressurised system. The flow inside the safety relief valve shows a number of interesting, yet complicated, features especially when a two-phase flow is involved.

Influence of Micro‐Scale Surface Texturing on Light Distribution From Luminescent Downshifting Layers for Next‐Generation Greenhouses

Global Challenges, Volume 10, Issue 9, September 2026.
This work investigates two different luminophores that convert ultraviolet to red light along with a wide range of microstructures to maximise outcoupling of the luminescence as well as the incoming solar radiation onto the greenhouse floor. Starting with small‐area (25 cm2) luminescent down‐shifting (LDS) layers, the best designs are then evaluated ...

Climate Change and Women's Mental Wellbeing in Ghana: Gendered Experiences of Displacement, Heat, Care, and Coping

Mental Health Science, Volume 4, Issue 3, September 2026.
ABSTRACT Climate change increasingly threatens mental wellbeing, yet its gendered psychological consequences remain insufficiently understood in Ghana. This qualitative multiple‐case study examined how place‐specific climate hazards shape women's distress, trauma, resilience, and coping in Salakope, a coastal community affected by sea encroachment and ...

Toward Peace With Nature: Protected Areas Effectively Mitigate Wild Ungulate‐Livestock Competition Despite Spatial Mismatch on the Qinghai‐Tibet Plateau

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Competition for forage between wild ungulates and grazing livestock poses a critical challenge for sustaining grassland ecosystems and pastoral livelihoods. Protected areas (PAs) may mitigate competition, but quantitative multi‐species assessments that simultaneously integrate habitat overlap, forage availability, and conservation ...

Framing Displacement, Forcing Perspective: Black Visual Geographies and the Crisis of Homelessness in Oakland

Antipode, Volume 58, Issue 5, September 2026.
ABSTRACT While Black and visual geographies have examined the image's racial and spatial power, more work is needed to analyze how racial frames of view become spatially embedded. This paper advances such a practice by analyzing news images of homelessness in Oakland.

Hidden Mould in the Air: A Practical Narrative Mini‐Review of Invasive Mould Infection Prevention for High‐Risk Patients and Clinicians

Mycoses, Volume 69, Issue 9, September 2026.
ABSTRACT Airborne mould spores, including those of the Aspergillus species, are ubiquitous both indoors and outdoors. While they are generally harmless, inhaled spores can cause severe infections, particularly invasive pulmonary aspergillosis, in patients with impaired immune defences.

The Painterly Materiality of Clouds in Antony and Cleopatra and Hamlet

Renaissance Studies, Volume 40, Issue 4, Page 589-608, September 2026.
Abstract This article examines the cloud‐gazing scenes in Antony and Cleopatra and Hamlet through the lens of early modern artistic theory and material practices, particularly the art of limning. Building upon existing philosophical and poetic interpretations of Shakespearean clouds as metaphors for ephemerality and memory, the essay argues that the ...
