True metabolizable energy of moist‐soil seeds among dabbling duck species

Wildlife Society Bulletin, EarlyView.
We quantified TMEN for moist‐soil plant seed species (Cyperus erythrorhizos, Cyperus iria, Panicum rigidulum, Polygonum hydropiperoides, Polygonum lapathifolium, Sesbania herbacea) among 3 species of dabbling duck (mallard [Anas platyrhynchos], northern pintail [A. acuta], and green‐winged teal [A. crecca]).

Optimizing sludge dewatering efficiency with ultrasonic Treatment: Insights into Parameters, Effects, and microstructural changes

Ultrasonics Sonochemistry
Sludge dewatering plays a critical role in the efficient and cost-effective management of wastewater treatment plants. Ultrasonic treatment has emerged as a promising technique for improving dewatering processes. This study aims to evaluate the impact of

Layered Radial Aquifer Model for Open‐Pit Mine Closure with Managed Aquifer Recharge

Groundwater, EarlyView.
A radially symmetric layered aquifer model (unconfined–aquitard–confined) coupled to a pit‐lake water balance is developed to screen managed aquifer recharge (MAR) after open‐pit mine closure. Dimensionless type curves quantify trade‐offs between pit recovery time, pumping/recycling, and unconfined mounding as functions of aquifer time scales, aquitard

Theoretical and experimental study on drawdown and foundation pit deformation under the influence of dewatering and excavation in unconfined aquifers

Results in Engineering
: This paper employs a combined approach of laboratory-scale experiments and theoretical calculations to analyze the influence of foundation pit dewatering on drawdown, lateral deformation of the diaphragm wall, and surface subsidence.

Macroinvertebrate community responses to a dewatering disturbance gradient in a restored stream [PDF]

Hydrology and Earth System Sciences, 2011
Dewatering disturbances are common in aquatic systems and represent a relatively untapped field of disturbance ecology, yet studying dewatering events along gradients in non-dichotomous (i.e. wet/dry) terms is often difficult.

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Dewatering Ultrafine Slurries [PDF]

, 2015
Dewatering has been a technical and economical barrier to the stabilization of coal tailings and the utilization of ultrafine coal particles from coal preparation. While substantial progress continues to be made in conventional dewatering technologies, a

Electro-dewatering (EDW) as Hybrid Dewatering Technology: Influence of Operating Parameters and Energy Efficiency

, 2023
Electro-dewatering (EDW) is a hybrid technology for separating liquids from solids in the wastewater sludge dewatering process. EDW has excellent prospects because it is able to remove water from sludge with high efficiency and low energy consumption ...
