Bioavailability of Cu and Zn in raw and anaerobically digested pig slurry [PDF]

, 2009
The impact of anaerobic digestion on the bioavailability of copper and zinc from pig slurry was assessed. Both chemical and biological approaches were used independently on raw slurry (RS) and anaerobically digested pig slurry (DS).

Sludge solidification based on carbon dioxide foam cement slurry

Yantu gongcheng xuebao
River and lake dredging will produce a large amount of dredged sludge with high water content and compressibility. Using the carbon dioxide as the foam gas source to prepare carbon dioxide foam cement slurry and use it as the solidification material to ...

Batch Settling and Low-Pressure Consolidation Behaviors of Dredged Mud Slurry: Steady-State Evaluation and Mechanism Study

, 2023
Since the exploration of the characteristics of dredged mud slurry during batch settlement and low-pressure consolidation (less than 100 kPa) is still insufficient, the determination of the optimal time to start the vacuum preloading method (VPM) on ...

Nitrous oxide emissions from multiple combined applications of fertiliser and cattle slurry to grassland [PDF]

, 2008
Fertiliser and manure application are important sources of nitrous oxide (N2O) emissions from agricultural soils. The current default IPCC emission factor of 1.0% is independent of the type of fertiliser and manure, and application time, method and rate.

High and dry: the persistence of diverse coastal marsh communities depends on available upland area and connection to surrounding waters

Restoration Ecology, EarlyView.
Sea‐level‐rise and alterations to natural hydrology have contributed to coastal land loss. To combat coastal land loss and maintain the ecosystem services provided by marshes, marsh creation has been broadly implemented. Marsh creation projects can be performed in conjunction with the construction of elevated terrestrial ridges that seek to mimic ...

The Continental Shelf as a Site for Dredged Material Disposal, Northeast New Zealand [PDF]

, 2008
Disposal of dredged material has been an on-going problem in the Auckland Coastal Marine Area (CMA) since the early 1980s in New Zealand. Many disposal grounds have been established and used, but public concern over adverse effects resulted in their ...

Linking Abundance and Activity of Ammonia‐Oxidising Bacteria and Archaea in an Agriculturally Impacted First‐Order Stream

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Ammonia‐oxidising archaea (AOA) and bacteria (AOB) coexist in streambed sediments, but their contributions to nitrification remain unresolved. Using field sampling, sequencing, qPCR, microcosm incubations and modelling, we show that AOB dominated nitrification in streambed sediments despite lower abundance, emphasizing the importance of distinguishing ...

Experimental study on sedimentation and consolidation of soil particles in dredged slurry

KSCE Journal of Civil Engineering, 2017
Sedimentation and consolidation of dredged slurry is very complex in practice. A new Multilayer Extraction Sampling (MES) method was developed in this study to better understand the underlying law of sedimentation and consolidation of soil particles in slurries.

Effect of Turbulent Fluctuation on Settling Behavior of Dredged Slurry in Sheared Condition

KSCE Journal of Civil Engineering, 2021
For the land shortage problem upon the city development in coastal areas, it is of great importance to improve the overall understanding of the settlement behavior of dredged slurry and determine the required site water storage capacity as well as the mechanical properties of the newly formed dredged slurry.

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

Ibis, Volume 168, Issue 3, Page 876-889, July 2026.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.
