Equilibrium scour pattern around tandem piers at an intermediate below-critical inflow velocity

Journal of Hydrology and Hydromechanics
Scouring around bridge piers is one of the major reasons for bridge failure. A total of 20 experiments of scour around tandem piers were conducted in an open channel, at a subcritical inflow velocity (U/Uc=0.67) by placing an equal or smaller diameter ...

The plasticisation model of dye diffusion: Part 6

Coloration Technology, EarlyView.
Abstract Previously published data reported for the temperature dependency of the exhaustion of a mordant dye and acid dye, as well as both the exhaustion and fixation of a reactive dye and adsorption of a direct dye, on three different types of wool substrate, over a diverse range of dyeing temperatures and conditions, were re‐evaluated using the ...

Amidase‐Catalyzed Desorption of CO2 Captured in Aqueous Monoethanolamine (MEA) Solutions

Angewandte Chemie, Volume 138, Issue 33, 10 August 2026.
CO2 is captured in aqueous monoethanolamine (MEA) sorbents as carbamate and bicarbonate/carbonate. The subsequent desorption for storage or utilization is energy‐intensive, and this is a major impediment to industrial carbon dioxide removal (CDR) processes. The desorption process can be promoted by enzymes that catalyze the dissociation of distinct CO2‐

Effect of trapezoidal collars as a scour countermeasure around wing-wall abutments

Water Science and Engineering, 2018
Local scour around bridge abutments is a widespread problem that can result in structural failure. Collars can be used as a countermeasure to reduce the scour depth.

Numerical simulation on local scouring around a spur dike using equilibrium and non-equilibrium sediment transport models

PROCEEDINGS OF HYDRAULIC ENGINEERING, 2007
Around a spur dike, local scouring is occurred and it is necessary to estimate the maximum scour depth and the bed elevations around the dike. In this paper local scouring around the dike is simulated using the equilibrium and non-equilibrium sediment transport models.

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Coupling Effects of Flow Regimes and Pulsation Frequencies on the Spatio-Temporal Evolution of Monopile Scour Through Experimental Study

Journal of Marine Science and Engineering
Scour around monopile foundations is a pivotal challenge in nearshore engineering, as it undermines sediment support and threatens structural stability.

Field‐based evaluation of glass cullet as a supplementary sediment source for coastal restoration

Restoration Ecology, EarlyView.
There is an ever‐increasing demand for sand to support projects like beach nourishment and dune restoration, but dredging and mining sand causes environmental damage. Demonstrating the environmental and ecological compatibility of crushed and ground glass known as cullet to support coastal restoration projects could simultaneously divert waste from ...

A Natural History of ‘Annoyances’: Knowing Weeds and Weeding Knowledge in the Early Royal Society and its ‘Georgicall Committee’

Renaissance Studies, EarlyView.
ABSTRACT Seventeenth‐century virtuosi often figured themselves as epistemic weeders, grubbing up rank thickets of accumulated error. In this article, I argue that these metaphors were unnerved by the shifting status of weeds—ostensibly unwanted plants from the margins of cultivated space, unploughed land or the disturbed soils between growing crops—in ...

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...
