Flexural Performance and Morphological Characterization of Graphene Nanoparticle‐Reinforced Polylactic Acid (PLA) Nanocomposites

open access: yesJournal of Polymer Science, EarlyView.
PLA/GNP filaments containing 0–1.6 wt% graphene are produced by melt compounding and fabricated into flexural specimens using FDM. Their mechanical response and fracture morphology are evaluated through ASTM D790 three‐point bending tests and SEM. Increasing graphene loading promotes agglomeration and interlayer defects, reducing strength, stiffness ...

The effects of degassing, grain refinement & Sr-addition on melt quality-hot tear sensitivity relationships in cast A380 aluminum alloy

open access: yes, 2018
Hot tearing tendency of A380 with various element additions (Sr, Sr + Ti, Ti, B and B + Sr) was investigated. Constrained rod casting (CRC) hot tearing test method was used to characterize the hot tearing sensitivity.

Managing Competency‐Based Resistance in Video‐Mediated L2 Peer Feedback Sessions

open access: yesTESOL Quarterly, EarlyView.
Abstract Though there is growing empirical evidence on managing advice resistance as an institutional work of higher status party with superior epistemic knowledge domain (e.g., trainer) across diverse settings (e.g., supervision meetings), there is still a lack of research on how second language (L2) learners handle peer resistance in real time once ...

The role of the Eastern Mediterranean in human evolution: recent results from Greece Le rôle du Bassin méditerranéen oriental dans l’évolution humaine : résultats récents en Grèce

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.

From Nominalisation to Passive in Old Tibetan: Reconstructing Grammatical Meaning in an Extinct Language1

open access: yesTransactions of the Philological Society, EarlyView.
Abstract Based on an analysis of the Old Literary Tibetan corpus—a corpus of the oldest documented Tibetic language—the present study provides evidence that literary Tibetan v3 verb stems (commonly termed ‘future’) initially encoded passive voice. New arguments put forward in this article range from Trans‐Himalayan nominal morphology to early Tibetan ...

Remoistering Of The Wood Before Planing - A Method For Improved Surface Quality?

open access: yes, 2015
It is beneficial if the machining of wooden products is done at a moisture content equal to the climate the product is meant to be used in. For indoor products in central heated houses such moisture content is about 5-10%. For planing this is often a too
