Simeon Cairns

Associate Professor Simeon Cairns
School of Sport and Recreation

Simeon’s main research area involves studying physiological mechanisms underpinning skeletal muscle fatigue. Of considerable interest has been the role of various electrolytes (K+, Na+, Ca2+, Cl-, H+ and lactate-) in impairing muscle cell function. The effect of such electrolytes has been investigated on membrane potential, action potentials, sarcolemmal excitability, and contractile function in isolated fast-twitch and slow-twitch muscle preparations. The importance of these electrolytes in a model of disuse (reduced physical activity) is being investigated. Another main topic of interest involves determining the ability of adrenaline and β-adrenergic agonists to influence skeletal muscle performance and understanding the mechanisms involved.

Nargis Afroj Chowdhury

Nargis Afroj Chowdhury
Research Officer

Nargis has been working on developing cellulose based electro-conductive composites for actuation and drug delivery. She has investigated the bending behaviour of regenerated cellulose-based ionic electro-active composites for the fabrication of soft actuators with improved actuation force and durability. She also focuses on the externally induced (electrically and magnetically) matrices de-swelling and other responses, which affect the release of drug from the matrices. The matrices can be used as transdermal implants. In addition, they have potential application as transdermal patches. The matrices showed fast release of drug i.e. more than 60% of the loaded drug was released within 1h, which is required for the treatment of illness in an emergency care. Nargis has published four papers, two are from the Scientific Academic Publishers, one from the Hindawi Publishing Corporation and one from the Royal Society of Chemistry.

Obstructive sleep apnoea (OSA) is a common upper airway respiratory system sleep disorder, and is considered one of the threatening diseases to the quality of life worldwide. It is characterized by repeated collapse and/or obstruction of the pharyngeal airway during sleep. It may result in many health implications such as hypertension, cardiovascular disease, stroke, low sexual drive in men and increased rate of sudden death.  For many years, continuous positive airway pressure (CPAP) has been proven to be the golden and the first line treatment for patients diagnosed with moderate to severe OSA, due to its non-invasive nature.  Unfortunately few side effects have been reported when using the CPAP such as headaches, ear pressure, nasal congestion and dry mouth. Also stroke symptoms were recorded for cardiovascular disease patients due to the high operating pressure. In order to make the CPAP more comfortable and reduce patients’ rejection, the objective of Sherif’s project was to determine the upper airway characteristics of OSA patients before and after using the CPAP and investigate how these characteristics differ from those of healthy subjects.


Dr Thomas Vuong

Dr Thomas Vuong
Honorary Research Fellow

Thomas’ research investigates the flow path in CPAP device, which consists of inlet & outlet ducts, a centrifugal fan, a humidifier and a mask.  It is a very complicated system due to restrictions of space and size, and this complication leads to the internal noise generation which not only comes from the centrifugal fan but also from other components. In this research, numerical simulations such as Computational Aero-acoustics (CAA) with hybrid approach and Fluid-solid Interaction (FSI) method are used to investigate the flow-induced noise and vibration in CPAP device. Numerical simulations were conducted and analysed and the numerical results are verified by experimental results. From the simulated results, we identified several locations that potentially relate to the noise sources. Based on the findings, several modifications have been made in order to reduce the noise sources at interested locations. The character of aerodynamic sound generation of the internal flow inside the CPAP device has been identified using numerical simulation which is based on the computational aero-acoustic (CAA) with hybrid approach. Secondly, the influence of turbulent flow on the structure vibration was studied and analysed using finite element method (FEM). Finally, some of improvements were made based on several case studies.
