Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality

Journal of Polymer Science, EarlyView.
Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...

Scour and Scour Protection around Dynamically Active Marine Structures

, 2018
The fast growing and proven offshore wind energy industry provides the motivation for this study, in particular the prediction and control of scour around foundations. This thesis is concerned with the impact of the dynamic behaviour of marine structures

On flow-altering countermeasures for scour at vertical-wall abutment

, 2012
Results are presented for clear-water scour experiments at a vertical-wall abutment where the obstacle was modified with slots or roughening elements as flow-altering countermeasures against the erosion process.

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Nutritional properties, traditional uses and potential new applications for the sotol plant (Asparagaceae, Convallarioideae): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Sotol (Dasylirion spp.) is a resilient desert plant that sustains ecosystems, cultures and livelihoods in Chihuahua Desert. Our review highlights its nutritional properties, traditional uses and potential new applications in food, pharmaceuticals, renewable energy and water remediation. By synthesizing evidence across disciplines, we show how sotol can

Synergistic transition from type‐I‐like to type‐II‐like symptomology in a pyrethroid mixture and its impact on knockdown–mortality relationships in Musca domestica L

Pest Management Science, EarlyView.
In the present study, relationship between knockdown and mortality of insecticides was examined against the adult female housefly, Musca domestica. Type‐I pyrethroid insecticides showed a weak linkage, as early knocked down flies did not always result in mortality, while type‐II pyrethroids and organophosphates exhibited strong correlation between the ...

Scour holes: A data-driven risk-based analysis for scour holes in the Rhine-Meuse Delta

, 2019
In the Rhine-Meuse Delta over 100 scour holes are located. Many of these scour holes have dynamic behaviour and are growing in size and depth. A scour hole can lead to an increased probability of flooding.

Evaluating anisotropy‐based Monin–Obukhov similarity theory over canopies and complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study shows that an anisotropy‐based generalization of Monin–Obukhov surface‐layer scaling (SC23) applies readily across a wide range of atmospheric conditions with variable terrain, canopies, and land‐cover complexity. This work focuses on the scaling of velocity variances for 7 years at the 47 sites in the National Ecological Observation Network

Studies on the scour from flows downstream of an outlet

Though the local scour take rise by change of sediment transported through each section, generally, it is so complex phenomenon that the change of flow character in scour hole is closely related to progress of scour, and the development of scour is ...

Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures

River Research and Applications, EarlyView.
ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...
