Experimental investigation of cohesive soil erosion caused by translating submerged inclined water jets

Applied Ocean Research
Very limited research has been carried out to investigate sediment erosion caused by subaqueous inclined water jets, despite the fact that such water jets are used in subsea engineering (e.g., dredging, trenching, and deep sea mining).

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 ...

Effects of Sea‐Level Rise on Dredging and Dredged Estuary Morphology

Journal of Geophysical Research: Earth Surface, 2022
AbstractEstuaries and deltas worldwide are facing land loss and drowning due to sea‐level rise (SLR). Commonly home to ports, their channels are dredged and deepened for navigation. However, little is known about how such sediment management will interact with changing sediment transport patterns due to SLR. Using scale experiments, empirical relations

Ginsenoside Rg1 Ameliorates LPS‐Induced Sepsis‐Associated Lung Injury in Mice via VEGFC/D‐VEGFR3 Signaling‐Mediated Lymphangiogenesis and Lymphatic Remodeling

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Sepsis‐induced acute lung injury (ALI) remains challenging to treat, with conventional anti‐inflammatory therapies offering limited efficacy. The lymphatic system is crucial for removing edema and inflammatory mediators, and its impairment can exacerbate lung injury.

Cyclic Shear Responses of Saw-Tooth Artificial Rock Joints Under Constant Normal Load Conditions: Laboratory Investigation and Numerical Simulation

Geosciences
Understanding the movement behavior of upper blocks along rock joints or weak planes is crucial for the geological hazard forecast and prediction. This paper presents experimental and numerical investigations of a saw-tooth joint under shear and normal ...

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

Oikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Environmental monitoring of dredging at the Port of Angra dos Reis

Holos, 2019
Dredging activities in port areas are intended to expand the ports’ activities and maintain adequate depth in the access channels, berthing areas and basins of evolution. The environmental license granted for maintenance dredging in the port of Angra dos

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 ...
