Effects of slag substitution on physical and mechanical properties of fly ash-based alkali activated binders (AABs)

Publication ID: pub.1114222784

Keywords: Alkali Activated Cement; Fly Ash; Granulated Blast-furnace Slag; Microstructure; Mixture Proportioning; UK

Neat fly ash-based alkali activated binders require high activator dosages and high temperature curing in order to develop satisfactory mechanical properties. Blending ground granulated blast furnace slag (GGBS) with fly ash can give medium to high strengths without the need for high temperature oven curing. An extensive investigation was carried out for understanding the effects […]

Evolution of the Toarcian (Early Jurassic) carbon-cycle and global climatic controls on local sedimentary processes (Cardigan Bay Basin, UK)

Publication ID: pub.1100248145

Keywords: Carbon-isotope Stratigraphy; Cardigan Bay Basin; Global Weathering Rates; Gravity-flow Deposits; Oceanic Anoxic Event (OAE); Siderite; Toarcian (Early Jurassic); UK; Wales

The late Early Jurassic Toarcian Stage represents the warmest interval of the Jurassic Period, with an abrupt rise in global temperatures of up to ∼7 °C in mid-latitudes at the onset of the early Toarcian Oceanic Anoxic Event (T-OAE; ∼183 Ma). The T-OAE, which has been extensively studied in marine and continental successions from both hemispheres, […]

Investigating the feasibility of supply chain-centric business models in 3D chocolate printing: A simulation study

Publication ID: pub.1037480023

Keywords: Business Model Innovation; Case Study; Simulation; Supply Chain Management; UK; 3D Chocolate Printing

3D chocolate printing provides the technology for manufacturing chocolates layer-by-layer, thus offering customers enhanced product value and personalized consumption experience. As business models in the chocolate industry are closely associated with the profitability of the supply chain constituents, it seems appropriate to investigate the financial viability of these supply-chain centric business models prior to their […]

Methods and approaches to modelling the Anthropocene

Publication ID: pub.1002951971

Keywords: Complex System Models; Emergence; Feedbacks; Global; Scenarios; Simulation; Socio-ecological Systems

The ‘Anthropocene’ concept provides a conceptual framework that encapsulates the current global situation in which society has an ever-greater dominating influence on Earth System functioning. Simulation models used to understand earth system dynamics provide early warning, scenario analysis and evaluation of environmental management and policies. This paper aims to assess the extent to which current […]

Life cycle assessment of energy consumption and environmental emissions for cornstalk-based ethyl levulinate

Publication ID: pub.1040917576

Keywords: China; Cornstalk; Energy Consumption; Environmental Emissions; Ethyl Levulinate; Henan Province; Life Cycle Assessment

This study analysed the sustainability of fuel-ethyl levulinate (EL) production along with furfural, as a by-product, from cornstalk in China. A life cycle assessment (LCA) was conducted using the SimaPro software to evaluate the energy consumption (EC), greenhouse gas (GHG) and criteria emissions, from cornstalk growth to EL utilisation. The total life cycle EC was […]

Benchmarking and developing numerical Finite Element models of volcanic deformation

Publication ID: pub.1030005737

Keywords: Bolivia; COMSOL Multiphysics; Finite Element Analysis; Uturuncu Volcano; Volcano Deformation; Volcano Geodesy

Volcanic deformation during an unrest episode can provide valuable insights into potential magmatic plumbing system dynamics. Paramount to this is a model linking the recorded ground movement to the causative source at depth. Most models employ analytical techniques due to their simplicity, but these are limited in their approach due to a number of necessary […]
