An integrated social and natural sciences case study for the reuse of organic wastes as soil amendments

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Reusing organic waste materials, such as animal manure, as soil amendments reduces water and fertiliser demand, contributing to achieving the Sustainable Development Goals. However, organic wastes may contain contaminants of emerging concern (CECs), posing potential ecosystem and human health risks. Despite the importance of this issue, there is a lack

Dam It, I’m Stranded: Evaluating Fish Stranding Downstream of Two Hydropeaking Dams in Northern Ontario

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.

Research advance and application exploration of sludge dewatering flocculants

open access: yesGongye shui chuli
Activated sludge process is one of the most widely used processes for wastewater biological treatment. As the main by-product of activated sludge process,sludge with the high moisture content easily results in various problems such as the difficult ...

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

open access: yesBoreas, EarlyView.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Laboratory Testing Methods for Centrifugal Sludge Dewatering Processes [PDF]

open access: yes, 2013
Sludge dewatering is an important part of the municipal and industrial wastewater treatment. The purpose of sludge dewatering is to reduce organic ingredients, as well as the volume and weight of the sludge.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

open access: yesBoreas, EarlyView.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

Hydro-Mechanical Coupling Analysis of Field Pumping Test in Granite Residual Soil Site

open access: yesBuildings
In addressing the challenge that the settlement behavior of granite residual soil in South China during foundation pit dewatering cannot be fully understood due to its unsaturated characteristics, this study proposes and validates an unsaturated fluid ...

Identifying the pre‐Odra river system with hydroacoustic and seismic reflection imagery offshore Rügen Island, southern Baltic Sea

open access: yesBoreas, EarlyView.
Understanding the course and dynamics of ancient river systems, such as the pre‐Odra, provides valuable insights into the post‐glacial evolution of landscapes and riverine processes. The northwest‐trending pre‐Odra was an important drainage system of the European mainland into the Baltic Basin during and after the Scandinavian Ice Sheet retreat ...

Novel method for optimizing the dewatering rate of a coal-bed methane well

open access: yesEnergy Exploration & Exploitation, 2020
The reasonable dewatering rate in the single-phase water flow plays an essential role in pressure propagation and coal-bed methane production. However, current fluid velocity sensitivity experiments cannot provide an optimum dewatering rate for field ...

Actively decaying or just poorly preserved? Can we tell when plant and invertebrate remains in urban archaeological deposits decayed? [PDF]

open access: yes, 2004
We have recendy argued that poorly preserved delicate macrofossil remains of plants and invertebrates in near-surface deposits in York are in active decay, rather than being preserved in stasis, part-way down the decay trajectory.
