Flow Regime Transition in Countercurrent Packed Column Monitored by ECT [PDF]

, 2021
Vertical packed columns are widely used in absorption, stripping and distillation processes. Flooding will occur in the vertical packed columns as a result of excessive liquid accumulation, which reduces mass transfer efficiency and causes a large ...

Application of dynamic modelling and model‐based predictive control to enhance a cooling tower

The Canadian Journal of Chemical Engineering, EarlyView.
Model predictive control (MPC) applied to improve the operation of cooling towers. Abstract Model predictive control (MPC) differs from traditional feedback control by making predictions within a time horizon, providing better control actions for the process.

Population Changes and Emerging Challenges to Global Primary Education Provision

Population and Development Review, EarlyView.
Abstract Global demographic changes in recent decades have sharply altered the contexts in which governments provide education. Focusing on primary education, we demonstrate, first, that recent demographic trends have been highly polarizing for education systems worldwide. Persistent expansionary pressures burden some of the least‐resourced educational

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, Volume 309, Issue 7, Page 1797-1820, July 2026.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of
