H2 generation and sulfide to sulfoxide oxidation in H2O using sunlight with a model photoelectrosynthesis cell
(Elsevier, 2014-10-28)A summary of the recent advances in homogeneous light-driven catalytic oxidation reactions is provided either using sacrificial agents or with complete functional cells. In this work, a photoelectrosynthesis model cell ... -
Halogenated flame retardants in Irish waste polymers: Concentrations, Legislative compliance, and preliminary assessment of temporal trends
(Elsevier, 2022-07-20)Halogenated flame retardants (HFRs) were measured in 470 waste plastic articles from Ireland between 2019 and 2020. We identified articles containing concentrations of polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane ... -
Head-to-nerve analysis of electromechanical impairments of diffuse axonal injury
(Springer, 2018-11-14)The aim was to investigate mechanical and functional failure of diffuse axonal injury (DAI) in nerve bundles following frontal head impacts, by finite element simulations. Anatomical changes following traumatic brain injury ... -
Heterogeneity of structure and stress in the Rotokawa Geothermal Field, New Zealand
(American Geophysical Union (AGU), 2015-02-12)Geometric characterization of a geothermal reservoir's structures, and their relation to stress field orientation, is vital for resource development. Subsurface structure and stress field orientations of the Rotokawa ... -
A hierarchical single-pulse shock tube pyrolysis study of C-2-C-6 1-alkenes
(Elsevier, 2020-06-27)A single-pulse shock tube study of the pyrolysis of 2% C-2 - C-6 1-alkenes is presented at 2 bar in the tem-perature range 900-1800 K in the current study. Reactant, intermediate and product species are obtained and ... -
Hierarchical study of the reactions of hydrogen atoms with alkenes: A theoretical study of the reactions of hydrogen atoms with C2–C4 alkenes
(American Chemical Society, 2021-06-08)The present study complements our previous studies of the reactions of hydrogen atoms with C5 alkene species including 1- and 2-pentene and the branched isomers (2-methyl-1-butene, 2-methyl-2-butene, and 3-methyl-1-butene), ... -
A high rate tension device for characterizing brain tissue
(SAGE Journals, 2012-03-08)The mechanical characterization of brain tissue at high loading velocities is vital for understanding and modeling traumatic brain injury. The most severe form of traumatic brain injury is diffuse axonal injury, which ... -
High Time Resolution Astrophysics in the Extremely Large Telescope Era : White Paper
(2010)High Time Resolution Astrophysics (HTRA) concerns itself with observations on short scales normally defined as being lower than the conventional read-out time of a CCD. As such it is concerned with condensed objects such ... -
A high-pressure rapid compression machine study of n-propylbenzene ignition
(Elsevier ScienceDirect, 2013-08-28)This study presents new ignition delay data measured in a rapid compression machine over a wide range temperature, pressure and fuel/air ratio. This data is an extension of that measured previously (D. Darcy, C.J. Tobin, ... -
High-resolution analysis of parent-of-origin allelic expression in the Arabidopsis endosperm.
(2011)Genomic imprinting is an epigenetic phenomenon leading to parent-of-origin specific differential expression of maternally and paternally inherited alleles. In plants, genomic imprinting has mainly been observed in the ... -
High-resolution, wide-field object reconstruction with synthetic aperture Fourier holographic optical microscopy
(Optica, 2009)We utilize synthetic-aperture Fourier holographic microscopy to resolve micrometer-scale microstructure over millimeter-scale fields of view. Multiple holograms are recorded, each registering a different, limited region ... -
A high-speed bi-polar outflow from the archetypical pulsating star Mira A
(2009)Optical images and high-dispersion spectra have been obtained of the ejected material surrounding the pulsating AGB star Mira A. The two streams of knots on either side of the star, found in far ultra-viollet (FUV) GALEX ... -
High-time Resolution Astrophysics and Pulsars
(2008)The discovery of pulsars in 1968 heralded an era where the temporal characteristics of detectors had to be reassessed. Up to this point detector integration times would normally be measured in minutes rather seconds and ... -
Higher torsion in the Abelianization of the full Bianchi groups
(Cambridge University Press (Cambridge Journals Online), 2013-09)Denote by Q(root-m), with m a square-free positive integer, an imaginary quadratic number field, and by O-m its ring of integers. The Bianchi groups are the groups SL2(O-m). In the literature, so far there have been no ... -
Highlight Talk: Recent Results from VERITAS
(2009)VERITAS is a state-of-the-art ground-based gamma-ray observatory that operates in the very high-energy (VHE) region of 100 GeV to 50 TeV. The observatory consists of an array of four 12m-diameter imaging atmospheric Cherenkov ... -
Hindered rotor benchmarks for the transition states of free radical additions to unsaturated hydrocarbons
(Royal Society of Chemistry, 2020-11-03)The hindered internal rotors of 32 transition states (TSs) formed through four free radicals, namely methyl, vinyl, ethyl, methoxy (CH3, C2H3, C2H5, CH3) additions to acetylene, ethylene, allene, propyne, and propene ... -

The homological torsion of PSL_2 of the imaginary quadratic integers
(2013)The Bianchi groups are the groups (P)SL2 over a ring of integers in an imaginary quadratic number field. We reveal a correspondence between the homological torsion of the Bianchi groups and new geometric invariants, which ... -
Homology and K-theory of the Bianchi groups
