Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Structurally-driven magnetic state transition of biatomic Fe chains on Ir(001) [PDF]

open access: yes, 2009
Using first-principles calculations, we demonstrate that the magnetic exchange interaction and the magnetocrystalline anisotropy of biatomic Fe chains grown in the trenches of the 5x1 reconstructed Ir(001) surface depend sensitively on the atomic ...

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

open access: yesBoreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Exploring How Affordances of Play Materials Shape Chinese Parents' Interaction With Children: Media‐Elicited Focus Group Discussion

open access: yesChildren &Society, EarlyView.
ABSTRACT Existing literature on children's play materials predominantly reflects theoretical frameworks and empirical data generated in the Global North, where ideas of “developmental appropriateness” often overlook the socio‐cultural specificity of materials' affordances and parental expectations.

The Laser Scanner Technique: A Tool for Determining Shear Strength Parameters of Rock Mass Discontinuities

open access: yesApplied Sciences
When evaluating the shear strength of rock mass discontinuities, certain challenges arise due to the difficulty in quantifying the roughness characteristics of surfaces and the strength of asperities.

The spectral element method as an efficient tool for transient simulations of hydraulic systems

open access: yes, 2017
This paper presents transient numerical simulations of hydraulic systems in engineering applications using the spectral element method (SEM). Along with a detailed description of the underlying numerical method, it is shown that the SEM yields highly ...

Detection of nanoseismic events related to slope instabilities in the quarry district of Coreno Ausonio (Italy) [PDF]

open access: yes, 2016
Le cave per l’estrazione di materiale roccioso rappresentano contesti in cui possono aver luogo eventi di instabilità gravitativa causati dalle continue sollecitazioni cui sono soggette le pareti produttive, principalmente connesse alle vibrazioni dovute

Tillich's Schellingian Styles

open access: yesThe Heythrop Journal, EarlyView.
Abstract In this essay I contend that, whatever one might say about F.W.J. Schelling's historical and conceptual influence on Paul Tillich's doctrines, the overall style of Tillich's project can helpfully be dubbed Schellingian to the extent it mixes together discourses, genres, and vocabularies into an ever‐expanding whole. To the extent that anything

Bio-deterioration of stone and concrete by Melanopsis praemorsa in Gan-HaShlosha national park—A case study

open access: yesCase Studies in Construction Materials, 2020
Gan HaShlosha national park contain two ponds of running brackish water. Dams were built on the ponds in the 80 s. Some masonary from the dams, as well as other underwater structure, have deteriorated.
