ADAPTIVE PRE-EMPTIVE CONTROL OF VACUUM DEWATERING IN PAPER MANUFACTURING
IFAC Proceedings Volumes, 2002 Abstract Paper manufacturing involves the sequential removal of water from pulp by means of gravity, vacuum dewatering, mechanical pressing and thermal drying. This research proposes a new control topology for moisture content using surrogate measurements to infer in-process moisture content, and the pressure settings in the vacuum dewatering section

CLEAN – Soil, Air, Water, Volume 54, Issue 7, July 2026.This study demonstrates that stoichiometric Mg2+:PO43− excess (1.1:1) and slow 10‐min dosing are critical for maintaining low supersaturation, yielding large crystals (>0.84 mm) and rapid settling (5.5–10.1 cm/min). This strategy optimizes nutrient recovery (≥80%) and solid–liquid separation without flocculants, proving viable for complex industrial ...

Groundwater, Volume 64, Issue 4, Page 441-456, July/August 2026.Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure
Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1213-1242, July 2026.Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.

Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 2842-2861, June 2026.Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 506-538, June 2026.The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...
