Enhanced photostability of a Ruthenium(II) Polypyridyl Complex under highly oxidizing aqueous conditions by its partial inclusion into a cyclodextrin
(Wiley, 2016-01-08)The complex [Ru(bpy)2L]2+, where bpy=2,2′-bipyridine, L=4-(phenylethynyl)-2,2′-bipyridine, was prepared in its racemic and resolved forms (Δ and Λ). The phenylethynyl unit on the bipyridine for the complex acts as a binding ... -
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 ... -
Estimating average attributable fractions with confidence intervals for cohort and case control studies
(SAGE Publications, 2016-06-24)Chronic diseases tend to depend on a large number of risk factors, both environmental and genetic. Average attributable fractions were introduced by Eide and Gefeller as a way of partitioning overall disease burden into ... -
Evaluating the interaction of human serum albumin (HSA) and 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) liposomes in different aqueous environments using anisotropy resolved multi-dimensional emission spectroscopy (ARMES)
(Elsevier, 2022-01-07)Studying the interaction between plasma proteins and liposomes is critical, particularly for their use as drug delivery systems. Here, the efficacy of anisotropy resolved multidimensional emission spectroscopy (ARMES) for ... -
Evaluation of acridine in Nafion as a fluorescence-lifetime-based pH sensor
(2003)We report a novel fluorescence-lifetime-based pH sensing method that utilizes acridine incorporated into Nation (AcNaf) as the fluorescent indicator. The AcNaf sensor is excited using a 380 nm light emitting diode (LED) ... -
Evaluation of hand-held XRF for screening waste articles for exceedances of limit values for brominated flame retardants
(Environmental Protection Agency, 2019-03)Recent research has demonstrated the presence of restricted persistent organic pollutant (POP) brominated flame retardants (BFRs) in items such as children s toys and food contact articles. As the presence of these ... -
Evaluation of non-ideal piston stopping effects on the “adiabatic core” and ignition delay time simulation in rapid compression machines
(Elsevier, 2020-05-30)Piston creep and rebound are two non-ideal piston stopping behaviors in the rapid compression machine. Compared to nominal piston stopping, piston rebound/creep will result in a smaller/bigger 'adiabatic' core zone volume ... -
Evidence for long-term Gamma-ray and X-ray variability from the unidentified TeV source HESS J0632+057
(2009)HESS J0632+057 is one of only two unidentified very-high-energy gamma-ray sources which appear to be point-like within experimental resolution. It is possibly associated with the massive Be star MWC 148 and has been suggested ... -
Evolution and diversity of plant cell walls: from algae to flowering plants
(Annual Reviews, 2011-02-22)All photosynthetic multicellular Eukaryotes, including land plants and algae, have cells that are surrounded by a dynamic, complex, carbohydrate-rich cell wall. The cell wall exerts considerable biological and biomechanical ... -
Examination of oestrus-dependent alterations of bovine cervico-vaginal mucus glycosylation for potential as optimum fertilisation indicators
(Royal Society of Chemistry, 2021-03-09)Oestrus is the period in the sexual cycle of female mammals during which ovulation occurs, where they become most receptive to mating and are most fertile. Efficient detection of oestrus is a key component in successful ... -
Exceptional Vertex Operator Algebras and the Virasoro Algebra
(2008)We consider exceptional vertex operator algebras for which particular Casimir vectors constructed from the primary vectors of lowest conformal weight are Virasoro descendants of the vacuum. We discuss constraints on these ... -
Exceptionally bright TEV flares from the binary LS I+61 degrees 303
(IOP Publishing, 2016-01-20)The TeV binary system LS I +61 degrees 303 is known for its regular, non-thermal emission pattern that traces the orbital period of the compact object in its 26.5 day orbit around its B0 Ve star companion. The system ... -
Excess of rare novel loss-of-function variants in synaptic genes in schizophrenia and autism spectrum disorders
(Springer Nature, 2013-10-15)Schizophrenia (SZ) and autism spectrum disorders (ASDs) are complex neurodevelopmental disorders that may share an underlying pathology suggested by shared genetic risk variants. We sequenced the exonic regions of 215 genes ... -
An excitation emission fluorescence lifetime spectrometer using a frequency doubled supercontinuum laser source
(IOP Publishing, 2018-09-03)The accurate fluorescence analysis of complex, multi-fluorophore containing proteins requires the use of multi-dimensional measurement techniques. For the measurement of intrinsic fluorescence from tyrosine (Tyr) and ... -
Expansions of CAG·CTG repeats in immortalized human astrocytes.
(Oxford University Press, 2007)Expansions of trinucleotide repeats (TNRs) are the genetic cause for a number of neurodegenerative disorders. In some of these diseases, ongoing somatic expansions in the brain are thought to contribute to disease progression. ... -
An experimental and chemical kinetic modeling study of 1,3-butadiene combustion: Ignition delay time and laminar flame speed measurements
