Further Investigation of Solvent Synergists for Improved Performance of Poly(N-vinylcaprolactam)-Based Kinetic Hydrate Inhibitors
(Peer reviewed; Journal article, 2021)Poly(N-vinylcaprolactam) (PVCap) and related copolymers have been used as kinetic hydrate inhibitors (KHIs) to combat gas hydrate formation in oil and gas field production flow lines. It is known that the addition of certain ... -
Prioritising topics for developing e-learning resources in healthcare curricula: A comparison between students and educators using a modified Delphi survey
(Peer reviewed; Journal article, 2021)Background Engaging students in the e-learning development process enhances the effective implementation of e-learning, however, students’ priority on the topics for e-learning may differ from that of the educators. This ... -
N‑Oxide Polyethers as Kinetic Hydrate Inhibitors: Side Chain Ring Size Makes the Difference
(Peer reviewed; Journal article, 2021)The formation of gas hydrates in flow lines is one of the most severe problems for flow assurance in the gas and oil industry. Developing effective kinetic hydrate inhibitors (KHIs) to avoid the problem of gas hydrate ... -
Fosfomycin and Its Derivatives: New Scale Inhibitors for Oilfield Applications
(Peer reviewed; Journal article, 2022)Aminomethylenephosphonate-based scale inhibitors (SIs) have been widely studied and recognized for several decades to mitigate various oilfield scales. However, most of these compounds afforded several drawbacks, such as ... -
Welding procedure qualification record (WPQR) for welds fabricated at proximity
(Peer reviewed; Journal article, 2022)Maintaining the minimum allowable distance between proximity welds has always been considered a subject of debate among design engineers, welding engineers/inspectors and fabricators/engineering contractors. The scattered ... -
National Implementation of In Situ Simulation-Based Training in Helicopter Emergency Medical Services: A Multicenter Study
(Peer reviewed; Journal article, 2021)Objective Medical simulation is used in helicopter emergency services as a tool for training the crew. Using in situ simulation, we aimed to evaluate the degree of implementation, the barriers to completing simulation ... -
Home Security and Emergency Response: The Convenience vs Security Trade-off
(Peer reviewed; Journal article, 2021)The world is increasingly becoming more digitalised as advanced technologies become more affordable and easier to use. Growing digitalisation conjures up many questions about if the “rewards” and added convenience of ... -
Invasive cancerous area detection in non-muscle invasive bladder cancer whole slide images
(Chapter, 2022)Bladder cancer patients’ stratification into risk groups relies on grade, stage and clinical factors. For non-muscle invasive bladder cancer, T1 tumours that invade the subepithelial tissue are high-risk lesions with a ... -
