Concentrations of perfluoroalkyl substances in human milk from Ireland: Implications for adult and nursing infant exposure
(Elsevier, 2019-12-20)Concentrations of 10 perfluoroalkyl substances (PFASs) were measured in 16 pools of human milk from Ireland. Only four PFASs were detected (PFOA, PFNA, PFHxS and PFOS), with concentrations dominated by PFOA which was ... -
VERITAS detection of LS 5039 and HESS J1825-137
(Elsevier, 2019-11-07)With 8 h of observations, VERITAS confirms the detection of two very high energy gamma-ray sources. The gamma-ray binary LS 5039 is detected with a statistical significance of 8.8σ. The measured flux above 1 TeV is near ... -
Ultra-sensitive label free imaging below the resolution limit
(SPIE (Society of Photo-optical Instrumentation Engineers) Digital Library, 2019-02-02)Almost all known nanoscopy methods rely upon the contrast created by fluorescent labels attached to the object of interest. This causes limitations on their applicability to in vivo imaging. A new label-free spectral ... -
Experimental assessment of clinical MRI-induced global SAR distributions in head phantoms
(Elsevier, 2019-10-05)Accurate estimation of SAR is critical to safeguarding vulnerable patients who require an MRI procedure. The increased static field strength and RF duty cycle capabilities in modern MRI scanners mean that systems can easily ... -
Label free ultra-sensitive imaging with sub-diffraction spatial resolution
(IEEE, 2019-07-09)In this paper, we show a new way to break the resolution limit and dramatically improve sensitivity to structural changes. To realize it we developed a novel label free contrast mechanism, based on the spectral encoding ... -
Spatial frequency domain correlation mapping optical coherence tomography for nanoscale structural characterization
(AIP Publishing, 2019-09-16)Most of the fundamental pathological processes in living tissues exhibit changes at the nanoscale. Noninvasive, label-free detection of structural changes in biological samples pose a significant challenge to both researchers ... -
Occupational exposures in an equestrian centre to respirable dust and respirable crystalline silica
(MDPI, 2019-09-03)Abstract: Sand-based products are regularly used as footing material on indoor equestrian arenas, creating a potential occupational exposure risk for respirable crystalline silica (RCS) for equestrian workers training and ... -
Using the Agile software development lifecycle to develop a standalone application for generating colour magnitude diagrams
(Elsevier, 2019-05-11)Virtual observatories allow the means by which an astronomer is able to discover, access, and process data seamlessly, regardless of its physical location. However, steep learning curves are often required to become ... -
1064 nm acoustic resolution photoacoustic microscopy
(Wiley, 2018-12-03)Photoacoustic imaging is a noninvasive imaging technique having the advantages of high-optical contrast and good acoustic resolution at improved imaging depths. Light transport in biological tissues is mainly characterized ... -
Experimental assessment of MRI-induced temperature change and SAR distributions in phantoms
(NUI Galway, 2017-11-14)During an MR procedure, most of the transmitted RF power is transformed into heat within the patients’ tissue resulting from resistive losses, referred to as the specific energy absorption rate(SAR) (2). The EU standardisation ... -
Entertaining physics education: using an astronomy board game to enhance student learning and motivation
(GIREP-MPTL 2018, 2018-07-09)This study examines the effects of a novel Astronomy Board Game on students science performance, their attitudes towards learning Science through games and their perception of scientists. Post-primary students in Ireland ... -
Asteroid Day: a vehicle for raising public awareness of astronomy and space exploration among primary students in Ireland
(NUI Galway, 2018-03-24)Asteroid Day is a global awareness campaign which takes place annually to learn about asteroids, their impact and to increase awareness on how we can protect the Earth from future asteroid impacts. At the event students ... -
Game-based learning to engage students with physics and astronomy using a board game
(IGI Global, 2019)In this research article, the authors developed a novel astronomy board game and examined how this approach could facilitate the learning and teaching of astronomy topics covered in the new Irish Science Syllabus. A total ... -
Characterising glyphosate exposures among amenity horticulturists using multiple spot urine samples
(Elsevier, 2018-07-08)Background Glyphosate has recently received much public attention following its Group 2A probably carcinogenic to humans classification from the International Agency for Research on Cancer. Despite the widespread ... -
Performance review of multiple reference versus time domain optical coherence tomography
(IEEE, 2018-04-19)We present a detailed characterization of noise sources in multiple reference optical coherence tomography (MR-OCT) compared to time-domain OCT (TD-OCT). The noise characteristics were modeled based on the TD-OCT noise ... -
