Geological Characteristics and a New Simplified Method to Estimate the Long-Term Settlement of Dredger Fill in Tianjin Nangang Region

Journal of Marine Science and Engineering
Long-term settlement of dredger fill presents substantial challenges to infrastructure stability, particularly in coastal areas such as Tianjin Nangang, where liquefied natural gas (LNG) pipelines are vulnerable to deformation caused by differential ...

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Geotechnical behavior of soft dredger fill and deep sea soft clay

IOP Conference Series: Earth and Environmental Science, 2020
Abstract A full understanding of the geotechnical properties of deep sea soil is necessary for ocean engineering construction, and the basis is the evaluation and testing of undisturbed deep sea soil. Therefore, to investigate the geotechnical properties of deep sea soil, a series of experimental tests were conducted in this study ...

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

The Non‐Professional Virtues of the Hospice Volunteer

Journal of Applied Philosophy, EarlyView.
ABSTRACT Volunteers have long played a significant role in hospice care. Much of the care volunteers provide consists of weekly hour‐long in‐home visits. Home‐visiting hospice volunteers are not professionals, nor are they strangers or intimates. Hospice volunteers will not typically face moral dilemmas, nor be called upon to make dramatic decisions ...

Drivers of individual plant species contributions to β‐diversity are scale‐dependent

Oikos, EarlyView.
Species introductions and local extinctions of native species are driving biotic homogenisation in plant communities by reducing β‐diversity. Individual species vary in their contributions to β‐diversity (species contribution to β‐diversity; species‐β), yet our understanding of how species characteristics shape these contributions remains limited ...

Development of ± 550 kV DC GIS Basin Insulator

High Voltage, EarlyView.
ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.
