Truncated drumlins and their implication for past sea level reconstructions

open access: yesBoreas, EarlyView.
Coastal erosion of glacigenic sediments, particularly in the form of retreating drumlin bluffs, is a key process in paraglacial landscape evolution during periods of relative sea‐level (RSL) rise. As marine transgression reworks formerly subaerial glacial terrains, drumlins act as discrete sediment sources generating characteristic erosional and ...

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Complexity Navigation and Dual Enablement: Business Model Innovation at the Intersection of AI and the Circular Economy

open access: yesJournal of Product Innovation Management, EarlyView.
ABSTRACT The circular economy (CE) has emerged as a promising paradigm to address environmental challenges through resource efficiency, product life cycle transformation, and business model innovation. Yet, implementing circular business models remains challenging due to the complexity of coordinating stakeholders and managing large volumes of data ...

Bionic Structure on Complex Surface with Belt Grinding for Electron Beam Welding Seam of Titanium Alloy

open access: yesApplied Sciences, 2020
Electron beam welding (EBW) is widely used to weld titanium alloy parts such as aero-engine casing and blades. The surface quality after EBW has a significant influence on the aero-engine performance of those parts.

Disturbance legacies in arid environments shape recovery of former agricultural land

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Increasingly, arid agricultural land is being permanently taken out of irrigated production due to more frequent drought, higher temperatures, and the overconsumption of groundwater, with important ramifications for ecological recovery.

Single-grain cutting based modeling of abrasive belt wear in cylindrical grinding

open access: yesFriction, 2019
A systematic wear model of the cylindrical grinding process with an alumina abrasive belt from the perspective of single grain sliding wear was established in this study. The model consists of three parts: a single cutting force model derived by applying

Titian's Falconer: From Zorzone to Girolamo Cornaro

open access: yesRenaissance Studies, EarlyView.
ABSTRACT The identity of the sitter in Titian's Falconer and the issue of its dating have been subject to a false, yet very influential assumption: that The Falconer should be dated to a point as late as 1537 in order to connect it to the identity of Zorzone Cornaro (1517–1571), son of Girolamo (1485–1551).
