Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

Analysis of various parameters affecting weir design and fabrication of Weirs: An Overview

open access: yesMATEC Web of Conferences, 2018
Several geometric parameters influence weir discharge and it is explained in our present study. The PK weir is more efficient than rectangular labyrinth weir due to reduction in entrance losses of PK weir inlet key geometry.

Influences of sedimentation on overflow properties of sharp-crested weir

open access: yesInternational Journal of Sediment Research
A sharp-crested weir is the simplest type of weir and is mainly used for discharge measurement in open channels. The surface profile of an ogee weir also is designed based on the lower nappe profile of the free jet passing over a sharp-crested weir.

CEO Characteristics and CSR Governance Quality: Evidence From Europe

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Leveraging a sample of European listed firms, we investigate whether CEO duality, CEO tenure, and CEO membership in the CSR board committee are associated with the quality of corporate social responsibility (CSR) governance. Our findings indicate that CEO duality is negatively associated with CSR governance quality, whereas CEO membership on ...

Laboratory experiments and numerical model of local scour around submerged sharp crested weirs

open access: yesJournal of King Saud University: Engineering Sciences, 2020
The use of theoretical models, with multiphase flow (air, water, and sand), is lacking in prior research for the simulation and management of erosion around hydraulic structures. In this research, flume experiments and a Computational Fluid Dynamic (CFD)
