The Effect Of Cryogenic Machining Of S2 Glass Fibre Composite On The Hole Form And Dimensional Tolerances, Ugur Koklu, Sezer Morkavuk, Carol Featherston, Malik Haddad, David Sanders, Muhammad Aamir, Danil Yu Pimenov, Khaled Giasin

Research outputs 2014 to 2021

S2 glass fibre reinforced epoxy composites are widely used in aeronautical applications owing to their excellent strength to weight ratio. Drilling glass fibres can be cumbersome due to their abrasive nature and poor thermal conductivity. Moreover, the use of conventional coolants is not desirable due to contamination and additional costs for cleaning the machine part. An alternative is to use environmentally friendly coolants such as liquid nitrogen (LN2) which have been previously employed in machining metals and composites. The current study investigates the effect of drilling S2 glass fibre composite in a bath of LN2. The study aims to evaluate …

Gregory Haff, Shawn M. Arent, Nicholas Ripley, John J. Mcmahon, Martin Evans, Paul Comfort

Research outputs 2014 to 2021

Background: In-season competition and tournaments for team sports can be both long and congested, with some sports competing up to three times per week. During these periods of time, athletes need to prepare technically, tactically and physically for the next fixture and the short duration between fixtures means that, in some cases, physical preparation ceases, or training focus moves to recovery as opposed to progressing adaptations. Objective: The aim of this review was to investigate the effect of training frequency on muscular strength to determine if a potential method to accommodate in-season resistance training, during busy training schedules, could be …

Mixed Methods Study Into Social Impacts Of Work-Related Heat Stress On Ghanaian Mining Workers: A Pragmatic Research Approach, Victor Fannam Nunfam

Research outputs 2014 to 2021

Although mixed methods research proves significant in understanding complex social phenomenon, inadequate research has explored its utility in heat exposure studies. The convergent mixed methods analysis comprising 320 surveys and two focus group interviews were used to evaluate the social impacts of occupational heat stress on Ghanaian mineworkers to enlighten policy choices for the purpose of complementarity. The study contributes to mixed methods study by affirming the practical use of between-method triangulation and complementarity. The merged quantitative and qualitative results also showed adequate corroboration and complementarity between both data, to illustrate the social impacts of work-related heat stress on mining …

Weather Bodies: Experimenting With Dance Improvisation In Environmental Education In The Early Years, Jo Pollitt, Mindy Blaise, Tonya Rooney

Research outputs 2014 to 2021

This paper reports on insights gained from incorporating dance improvisation into a broader early years environmental education ethnographic research project. Findings are reported from a two-day workshop where a dancer was invited to work with young children to attune to the weather through their bodies. In these workshops, the practice of dance improvisation was used as a deliberate interference to disrupt the disconnected and disembodied ways in which weather is often taught to young children. The paper argues that when children attune with weather through the embodied and relational practice of dance improvisation, this challenges the common practice of learning …

Research outputs 2014 to 2021

Human induced pluripotent stem cells (hiPSCs) can generate a multiplicity of organoids, yet no compelling evidence currently exists as to whether or not these contain tissue-specific, holoclone-forming stem cells. Here, we show that a subpopulation of cells in a hiPSC-derived corneal epithelial cell sheet is positive for ABCB5 (ATP-binding cassette, sub-family B, member 5), a functional marker of adult corneal epithelial stem cells. These cells possess remarkable holoclone-forming capabilities, which can be suppressed by an antibody-mediated ABCB5 blockade. The cell sheets are generated from ABCB5+ hiPSCs that first emerge in 2D eye-like organoids around six weeks of differentiation and display …

Cantilever-Based Sensor Utilizing A Diffractive Optical Element With High Sensitivity To Relative Humidity, Catherine M. Grogan, Faolan Radford Mcgovern, Rory Staines, George Amarandei, Izabela Naydenova

Articles

High-sensitivity and simple, low-cost readout are desirable features for sensors independent of the application area. Micro-cantilever sensors use the deflection induced by the analyte presence to achieve high-sensitivity but possess complex electronic readouts. Current holographic sensors probe the analyte presence by measuring changes in their optical properties, have a simpler low-cost readout, but their sensitivity can be further improved. Here, the two working principles were combined to obtain a new hybrid sensor with enhanced sensitivity. The diffractive element, a holographically patterned thin photopolymer layer, was placed on a polymer (polydimethylsiloxane) layer forming a bi-layer macro-cantilever. The different responses of the …

Monitoring Stem Cell Differentiation Using Raman Microspectroscopy: Chondrogenic Differentiation, Towards Cartilage Formation, Francesca Ravera, Esen Efeoglu, Hugh Byrne

Articles

Mesenchymal Stem Cells (MSCs) have the ability to differentiate into chondrocytes, the only cellular components of cartilage and are therefore ideal candidates for cartilage and tissue repair technologies. Chondrocytes are surrounded by cartilage-like extracellular matrix (ECM), a complex network rich in glycosaminoglycans, proteoglycans, and collagen, which, together with a multitude of intracellular signalling molecules, trigger the chondrogenesis and allow the chondroprogenitor to acquire the spherical morphology of the chondrocytes. However, although the mechanisms of the differentiation of MSCs have been extensively explored, it has been difficult to provide a holistic picture of the process, in situ. Raman Micro Spectroscopy (RMS) …
