Development of the porcelain tiles by the partial substitution of feldspar with fly ash [PDF]
, 2020 Fly ash properties are unusual among engineering materials. Typically used for embankment construction, fly ash is well known in the production of cement, concrete and brick. Fly ash is one of the palm oil waste products from the combustion of palm fiber

Children &Society, EarlyView.ABSTRACT Developmental psychology continues to shape how adults engage with children about death and dying. This influences whether children are included in rituals surrounding human and other‐than‐human bodies. Figurations of the innocent, immature and vulnerable child still dominate adult imaginaries of young children's understandings of mortality ...

Low Cost Fly Ash - Sand Stabilization Roadway, Construction Report, HR-259, 1986 [PDF]
, 1986 Fly ash, a by-product of coal-fired electricity generating plants, has for years been promoted as a material suitable for highway construction. Disposal of the large quantities of fly ash produced is expensive and creates environmental concerns.

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)
Fisheries Oceanography, EarlyView.ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

‘This Is Not Europe’: Investigating the Commission's Anti‐Populist Articulation of ‘European Values’
JCMS: Journal of Common Market Studies, EarlyView.Abstract Whilst ‘populism’ is often considered antithetical to ‘European values’, how this contrast shapes the very meaning of such ‘values’ remains underexplored. This article investigates the European Commission's anti‐populist articulation of ‘European values’, which constructs ‘populism’ as their constitutive outside.

Effective Removal of Fe and Ca From Coal Fly Ash for High-Purity and High-Surface-Area Zeolite X Synthesis: A Comparative Study of Acid Refluxing and Acid Roasting Methods. [PDF]
ChemistryOpenCoal fly ash (CFA) is an abundant industrial waste rich in silica and alumina and represents a viable feedstock for zeolite synthesis; however, high levels of calcium and iron limit zeolite purity and crystallisation. This study evaluates acid refluxing and acid roasting as pre‐treatment strategies for the simultaneous removal of Ca and Fe from high ...
