Research outputs 2022 to 2026

Background: Pleural effusions often cause disabling breathlessness, however the mechanism is unknown. Patients with pleural effusions are subjected to pleural fluid drainage on a ‘trial and error’ basis, as symptom relief varies. This population commonly complain of bendopnoea (breathlessness on bending forward) which has not been investigated. Our pilot data found bendopnoea was significantly associated with presence of pleural effusion. The PLEASE-3 study will evaluate bendopnoea as a screening test for effusion-related breathlessness, its predictive value of symptomatic benefits from fluid drainage and explore its underlying physiological mechanism. Methods: PLEASE-3 is a multi-centre prospective study. Eligible patients are assessed at …

Acclimation To Warming But Not Hypoxia Alters Thermal Tolerance And Metabolic Sensitivity In An Estuarine Crustacean, Rebecca Bridge, Manuela Truebano, Michael Collins

School of Biological and Marine Sciences

Coastal species are challenged by multiple anthropogenic stressors. Plasticity may buffer the effects of environmental change, but investigation has largely been restricted to single-stressor performance. Multistressor studies have often been short-term and relatively less is known about the consequences of plasticity under one stressor for performance under another. Here, we aimed to test for the effects of thermal or hypoxic acclimation on thermal tolerance in the amphipod Gammarus chevreuxi. Animals were chronically exposed to raised temperature or hypoxia prior to determination of upper thermal limits and routine metabolic rate (RMR). Warm acclimation increased all metrics of thermal tolerance, but hypoxic …

Two-Buoy And Single-Buoy Floating Wave Energy Converters: A Numerical Comparison, Demin Li, Xiaochen Dong, Alistair G.L. Borthwick, Sanjay Sharma, Tianyuan Wang, Heao Huang, Hongda Shi

School of Engineering, Computing and Mathematics

A numerical model of two-buoy and single-buoy floating wave energy converters (WECs) is developed based on a modified nonlinear version of WEC-Sim. The model is validated against experimental data from a 1:5 geometric scale model of a two-buoy floating WEC. Nonlinear behavior is primarily attributed to viscous damping and mechanical friction effects. It is found that a modified version of WEC-Sim obtained by correcting the phase of the wave excitation force in the source code provides an accurate representation of a two-buoy WEC operating in either linear or nonlinear mode. An equivalent single-buoy WEC is modeled by locking the two-buoys …

Experimental Investigation Of Mechanical Properties Of Ggbs-Fa-Sf Blended Geopolymer Concrete At Elevated Temperatures, Tan Wang, Min Yu, Hanjie Lin, Dawang Li, Long Yuan Li

Purkinje Cell Dysfunction Causes Disrupted Sleep In Ataxic Mice, Luis E Salazar Leon, Amanda M Brown, Heet Kaku, Roy V Sillitoe

Duncan NRI Faculty and Staff Publications

Purkinje cell dysfunction disrupts movement and causes disorders such as ataxia. Recent evidence suggests that Purkinje cell dysfunction may also alter sleep regulation. Here, we used an ataxic mouse model generated by silencing Purkinje cell neurotransmission (L7Cre;Vgatfx/fx) to better understand how cerebellar dysfunction impacts sleep physiology. We focused our analysis on sleep architecture and electrocorticography (ECoG) patterns based on their relevance to extracting physiological measurements during sleep. We found that circadian activity was unaltered in the mutant mice, although their sleep parameters and ECoG patterns were modified. The L7Cre;Vgatfx/fx mutant mice had decreased wakefulness and rapid eye movement (REM) sleep, …

The Effect Of Carbon Pricing On Firm Performance: Worldwide Evidence, Tinghua Duan, Frank Weikai Li, Hong Zhang

Research Collection Lee Kong Chian School Of Business

Economists recommend combating climate change with carbon pricing; however, a major block to pricing emissions is concerns about economic costs. This paper examines the impacts of carbon pricing initiatives on the operating performance and market value of publicly listed firms around the world. Using the staggered enactment of carbon pricing initiatives across jurisdictions and a triple difference approach, we find a significant reduction in the profitability and value of carbon-intensive firms relative to low-emission firms after the enactment of carbon pricing policies. The reduction in firm profits is driven by both a decrease in sales growth and an increase in …
