Valorization of saline dredged sludge by low-carbon geopolymer production: Salt content impact, mechanisms, and carbon emissions

Results in Engineering
This study demonstrates a green and low-carbon approach for valorizing saline dredged sludge (DS) by producing geopolymers from DS combined with fly ash (FA) and ground granulated blast furnace slag (GGBS), activated by an alkaline activator ...

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.

Impact of operational parameters on turbidity generation in cutter suction dredging: Insights from a numerical model and sensitivity analysis

Applied Ocean Research
The cutter suction dredger (CSD) is one of the main vessels utilized in the dredging industry. The dynamic actions related to its rotating cutter head are the main trigger for sediment release and turbidity generation by this vessel.

Climate‐driven intraspecific shifts in seed germination phenology: Consequences for native temperate woodland restoration and regeneration

PLANTS, PEOPLE, PLANET, EarlyView.
As climate change alters seasonal patterns, temperate tree populations face a growing risk of phenological mismatch, where seed dispersal and germination no longer align with favourable conditions for survival. This study predicted how warming by the end of the century will affect seed dormancy breaking and germination in populations of three UK tree ...

Experimental and numerical flow field study of submerged translating impinging inclined water jets

Flow
This study investigates the influence of multiple jet parameters on the flow field of translating impinging inclined water jets. We conducted full-scale stereoscopic particle image velocimetry and pressure measurements and three-dimensional computational
