Machine Learning to Predict Workability and Compressive Strength of Low- and High-Calcium Fly Ash–Based Geopolymers

Crystals
The potential substitution of Portland cement–based concrete with low- and high-calcium fly ash–based geopolymers was investigated. However, predicting the workability and compressive strength of geopolymers with the desired physical and mechanical ...

Stabilising Routines in Complex Emergencies: How Basic Service Continuity Shapes Perceived Security

Public Administration and Development, EarlyView.
ABSTRACT This study examines how locally embedded actors describe the relationship between basic service continuity and perceived security in complex emergencies, with particular attention to the stabilisation of everyday routines. Using Proximity‐Predictability‐Attributability (PPA) as an analytic lens, we trace how interviewees relate access to water,

Mechanically robust biochar‐modified polystyrene foam with enhanced flame retardancy using halogen‐free additives

Polymer International, EarlyView.
Halogen‐free biocomposite polystyrene foams were fabricated via pilot‐scale supercritical CO2 extrusion using expandable graphite, melamine polyphosphate, biochar, and recycled polymer. The optimized formulation exhibited refined cellular morphology, enhanced flame retardancy (limiting oxygen index of 25%, rapid self‐extinguishing), and improved ...

Project Management Methodologies of International Development Agencies and the Concept of Sustainable Project Management

Sustainable Development, EarlyView.
ABSTRACT This research explores to what extent the ideas and notions of sustainable project management (SPM) are reflected in the project management methodologies of three selected international development agencies. A conceptual framework is developed, and a deductive content analysis is performed.
