EFFECT OF POLYMERIC POWDER ON THE FRICTION AND WEAR OF SAND CONTAMINATED GREASED SURFACES [PDF]
Journal of the Egyptian Society of Tribology, 2010 The present work aims to develop the abrasion resistance of surfaces lubricated by contaminated greases. The intended development can be achieved by reducing the effect of abrasive action of sand particles on the wear of the friction surfaces.

British Educational Research Journal, EarlyView.Abstract This article examines how national education in Hong Kong functions as a contested arena in which state and non‐state actors struggle over the meaning of citizenship, identity and schooling. Using inductive frame analysis of 319 news articles (2020–2025) from five Chinese‐ and English‐language outlets, it identifies diagnostic, prognostic and ...

Flourishing through adventure learning: A (semi)cautionary tale
British Educational Research Journal, EarlyView.Abstract Studies suggest that adventure learning can develop children's cognitive skills and promote social and emotional learning. However, evidence is needed as to whether the design of adventure learning—school‐based or external/residential—plays a role in that development/promotion, and whether learning gains are maintained.

ELECTRIC STATIC CHARGE GENERATED FROM THE FRICTION OF TEXTILES [PDF]
Journal of the Egyptian Society of Tribology, 2013 The wide use of polymer fibres in textiles necessitates to study their electrification when they rubbing other surfaces. The electric static charge generated from the friction of different polymeric textiles sliding against cotton textiles, which used as

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, EarlyView.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.
