Analysis of Influence of Ultra-High Pressure Water Jet Cutting Pressure Sequence on Pressure Relief and Reflection Improvement of Coal Seam

open access: yes, 2023
In order to explore the pressure relief effect of the two combined pressure relief and antireflection technologies of ultra-high pressure water jet cutting before pressure and pressure before cutting, theoretical analysis, numerical simulation, and field

Two phase discharge flow prediction in safety valves [PDF]

open access: yes, 2013
Safety Relief Valves (SRV) are necessary elements in the protection of any pressurised system and the prediction of the expected discharge flows is an important consideration for the valve sizing to ensure that rupture pressures do not occur.

That sinkin’ feeling: Environmentally induced distress on a disappearing island

open access: yesMedical Anthropology Quarterly, EarlyView.
Abstract Residents of Tangier Island, Virginia, a subsiding island in the Chesapeake Bay, embody psychosocial dimensions of environmental change. Analysis of ethnographic data shows islanders’ experiences and articulations of anxiety, panic, and despair as “that sinkin’ feeling,” resulting from the stress of living with the long‐term threat of imminent

Principle and practice of hydraulic softening top-cutting and pressure relief technology in weakly cemented strata

open access: yesFrontiers in Earth Science
Extremely thick and hard roofs are difficult to break in the mining of a working face, and the large area of the suspended roof easily induces a strong ground pressure or dynamic impact disasters.

AI Public Value Creation: Data Encoding, Aggregation, and Algorithmic Computation

open access: yesPublic Administration, EarlyView.
ABSTRACT AI systems in public administration challenge the premise that value creation arises from managers' strategic mediation among the vertices of Moore's strategic triangle: Public value, legitimacy, and operational capacity. AI imposes new logics that reshape vertices and their interaction dynamics.

The technology of gob-side entry retaining supported by flexible formwork wall with roof cutting and pressure relief for composite roof in deep mine

open access: yesGong-kuang zidonghua, 2021
In Lianghuai area of China, due to the influence of the large buried depth of the mine and the complicated roof conditions, when gob-side entry is retained, the roof deformation of the gob-side entry retaining is large, the coal side is easily extruded and the floor heave is serious.

When insurers retreat: The governance of wildfire disasters and how FAIR plans allocate climate risk

open access: yesRisk Management and Insurance Review, EarlyView.
Abstract As wildfire risk accelerates private insurer retreat, state‐governed FAIR Plans increasingly serve as the primary coverage available in hazard‐prone areas. This paper analyzes these residual markets as instruments of disaster governance, arguing that their design reflects distributive political choices regarding risk allocation.

Refining Transit‐Oriented Development Assessment: Ecological Conditions as a Critical Supplement

open access: yesTijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract Existing transit‐oriented development (TOD) assessments rarely examine whether station environments also support everyday ecological functions, including recreation access, thermal moderation, restoration and biodiversity. We developed a Node–Place–Design–Eco (NPDE) diagnosis for 92 Hong Kong railway station areas, combining conventional TOD ...
