AI‐Powered Virtual Patients in Health Professions Education: Learner Engagement and Knowledge Application

Journal of Dental Education, EarlyView.
ABSTRACT Purpose/Objectives Immersive educational technologies, including applications of artificial intelligence in education (AIED), are increasingly used to develop clinical skills in health professions education. This study evaluated the feasibility and perceived value of integrating an artificial intelligence (AI)‐enabled virtual patient platform ...

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

Journal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

Induced drilling strains in glass fibre reinforced epoxy composites [PDF]

, 2013
Residual strains induced by drilling of glass-fibre reinforced polymers (GFRP) were determined using a hybrid experimental-numerical methodology. Experimentally, a set of GFRP specimens were drilled under well-defined tensile (calibration) stresses ...

An Experimental Approach on Pearl Shell (Pinctada margaritifera) for a Microwear Study of Shell Artefacts From French Polynesia

Archaeometry, EarlyView.
ABSTRACT Pinctada margaritifera (black‐lipped pearl oyster) artefacts are ubiquitous in the archaeological record throughout the Pacific and particularly in Polynesia. Despite efforts towards the development of typologies, the lack of microwear and use‐wear studies has prevented the development of technological approaches. We used 20 pearl shell valves

Chironomid‐based summer temperature reconstruction of the Eemian–Weichselian transition at Lichtenberg, northern Germany

Boreas, EarlyView.
Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over

Rotary - percussion drilling method - historical review and current possibilities of application [PDF]

, 2015
'Faster, deeper, cheaper' -it is not just a slogan, it is a motto of every oil company. The first application of rotary--percussion drilling method in drilling oil wells took place in early 60's of the XX century in the United States.

A bifacial paradise—The site of Ochtmissen, Germany, and its lithic assemblage in the context of the last glacial (early MIS 4) in the north‐central European Lowland

Boreas, EarlyView.
The Palaeolithic site of Ochtmissen (Lower Saxony, Germany) was excavated in fluvial terrace deposits during the winter of 1993/1994. The current study presents, for the first time, a thorough analysis of the lithic assemblage, encompassing its primary technological and typological characteristics, as well as the type and age of the fluvial deposits ...

New drilling methods for the conductor casing operations [PDF]

Acta Montanistica Slovaca, 2006
The necessity to apply casing to wells drilled in loose rock strata have recently created conditions for the modernization of old solutions and the development of new drilling technologies. The newest World's design and technological solutions for rotary,
