Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Lodge moraines: a common yet underreported end‐moraine type—a review

Boreas, EarlyView.
Lodge moraines are a distinct genetic type of end moraine formed by submarginal accretion of subglacial till; they are some of the largest end moraines in the world. Although underreported in the literature, they are of equal importance to push, dump and hummocky end moraines. End moraines are formed at glacier ice margins and show the extent of former

Clogmia albipunctata Larvae Influence the Odour Dynamics of Rotting Organic Matter

Entomologia Experimentalis et Applicata, EarlyView.
Drain flies live in organic waste. We investigated how drain fly larvae influence the unpleasant smells produced by sewage sludge and rotting nettle. Although the perception of these smells did not change significantly according to the public, chemical analyses showed that sewage sludge with drain fly larvae yielded a different composition of odors ...

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

Buildings
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 ...

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

Method for Studying Water Removal and Air Penetration during Through Air Drying of Tissue in Laboratory Scale

BioResources, 2023
Energy use, together with consumption of raw materials, machine clothing, and wet end chemicals, are some of the most critical aspects in successful tissue making today. This work was aimed at developing a laboratory-scale method of estimating dewatering

The Effect of Mine‐Related Groundwater Use and Management on Surface Water in the Middle Humboldt River Basin

Groundwater, EarlyView.
Abstract The Humboldt River, in Northern Nevada, USA, is a source of water for agricultural, municipal, and industrial uses. Mining has been active in Nevada since the 1800s. The recognition that groundwater withdrawal for many purposes—including mining—has the potential to deplete streamflow has prompted studies of the Humboldt River Basin.

Demonstration of a High‐Resolution Passive Profiler for Characterizing the Distribution of PFAS in Groundwater: A Comparison of Methods in the Field

Groundwater Monitoring &Remediation, EarlyView.
Abstract Characterizing the concentration and mass flux spatial distributions at sites with complex hydrogeologic conditions is critical to evaluate the fate and transport of contaminants, as well as to design effective remediation programs. PFAS (per‐ and polyfluoroalkyl substances)‐contaminated sites are even more complex due to the large number of ...
