Potential of Saudi Arabian bauxite to produce low-carbon cement
CementTo produce calcium aluminate cement (CAC), bauxites are usually fused with lime/limestone at high temperature (1600 °C). At this temperature, the bauxite´s hydrates of alumina break down - dehydroxylation - and combine with calcium forming monocalcium ...

A Generalized Predictive Model for Displacement Washing of Partially Reslurried Filter Cakes
Chemical Engineering &Technology, Volume 49, Issue 8, August 2026.During displacement washing, partial reslurrying of the filter cake surface frequently occurs as an undesired side effect of wash liquid application, causing premature contamination of the wash liquid through mixing with cake impurities. This contamination can limit both washing efficiency and the achievable washing result.

Ecology and Evolution, Volume 16, Issue 8, August 2026.We used long‐term GPS tracking to quantify home‐range size and habitat selection of the endangered Red Goshawk across tropical savannas of northern Australia. Red Goshawks occupied extensive overall home ranges, with well‐defined core ranges centred on nest sites.

Nordgren PINNs to VQE: Advancing Hydraulic Fracturing Simulations in Shale Reservoirs
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 12, Page 4863-4878, 25 August 2026.ABSTRACT This study advances hydraulic fracturing simulations in shale reservoirs using two computational paradigms, Physics‐Informed Neural Networks (PINNs) and the Variational Quantum Eigensolver (VQE). PINNs were employed to solve Nordgren's equation, which governs fracture width evolution, by embedding physical laws into the neural network ...
