Phasing-out of legacy brominated flame retardants: The UNEP Stockholm Convention and other legislative action worldwide
(Elsevier, 2020-08-18)Due to their toxicity and persistence, several families of brominated flame retardants (BFRs) have been listed as persistent organic pollutants (POPs) in the Stockholm Convention, a multilateral treaty overseen by the ... -
Phosphate diester cleavage, DNA interaction and cytotoxic Activity of a bimetallic bis(1,4,7-triazacyclononane) zinc complex
(Wiley, 2014-06-24)The dinuclear zinc complex [Zn-2{bcmp(-H)}(mu-Cl)](ClO4)(2)center dot H2O {bcmp = 2,6-bis(1,4,7-triazacyclonon-1-ylmethyl)-4-methylphenol} has been synthesized and structurally characterized. The DNA binding affinity was ... -
A phosphate-targeted dinuclear Cu(II) complex combining major groove binding and oxidative DNA cleavage
(Oxford University Press, 2018-09-17)Free radical generation is an inevitable consequence of aerobic existence and is implicated in a wide variety of pathological conditions including cancer, cardiovascular disease, ageing and neurodegenerative disorder. Free ... -
Piezoacoustic wave spectra using improved surface impedance matrix: Application to high impedance-contrast layered plates
(2008)Starting from the general modal solutions for a homogeneous layer of arbitrary material and crystalline symmetry, a matrix formalism is developed to establish the semianalytical expressions of the surface impedance matrices ... -
Piezoelectric Love waves on rotated Y-cut mm2 substrates
(IEEE, 2006-11)Consider a layer consisting of a m3m dielectric crystal, with faces cut parallel to a symmetry plane. Then bond it onto a semi-infinite mm2 piezoelectric substrate. For an X- or Y-cut of the substrate, a Love wave can ... -
Pilot study to investigate indoor air quality (IAQ) in energy efficient homes in Ireland: Report prepared for EPA STRIVE and Sustainable Energy Authority of Ireland
(School of Physics, NUI Galway, 2010-09)Within this pilot study a number of Indoor air pollutants were measured in five energy efficient homes built to enhanced standards of air tightness of between 0.75 m3 /hr/m2 and 8.75 m3 /hr/m2 . The five homes were ... -
Planar [Ni-7] discs as double-bowl, pseudo metallacalix[6]arene host cavities
(RSC, 2010-09-19)We report three heptanuclear[Ni-7] complexes with planar disc-like cores, akin to double-bowl metallocalix[6]arenes, which form molecular H-bonded host cavities. -
A point-distribution index and its application to sensor-grouping in wireless sensor networks
(ACM, 2006)We propose [i], a novel index for evaluation of point-distribution. [i] is the minimum distance etween each pair of points normalized by the average distance between each pair of points. We find that a set of points that ... -
Pollination ecology of Desmodium setigerum (Fabaceae) in Uganda; do big bees do it better?
(2016-09)Explosive pollen release is documented in many plant families, including the Fabaceae. Desmodium setigerum E. Mey (Fabaceae) is a perennial herb with single trip explosive pollen release found in eastern Africa, and the ... -
Population‐based identity‐by‐descent mapping combined with exome sequencing to detect rare risk variants for schizophrenia
(Wiley, 2019-02-23)Genome‐wide association studies (GWASs) are highly effective at identifying common risk variants for schizophrenia. Rare risk variants are also important contributors to schizophrenia etiology but, with the exception of ... -
Portable X-ray fluorescence for the detection of POP-BFRs in waste plastics
(Elsevier, 2018-05-26)The purpose of this study was to establish the efficacy of portable X-ray fluorescence (XRF) instrumentation as a screening tool for a variety of end of life plastics which may contain excess amounts of brominated flame ... -
Post-buckling development in soft particulate composites
(Elsevier, 2023-07-26)In this paper, we investigate the post-buckling development of instability-induced patterns in soft particulate composites. Upon reaching the critical strain level, the composite experiences microstructural buckling. ... -
The Poynting effect
(American Association of Physics Teachers, 2020-11-19)Intuition suggests that twisting a cylinder will shorten it, but here it is shown that for a cylinder of an incompressible material, like rubber, twisting will always produce elongation. -
Poynting effect of brain matter in torsion
(Royal Society of Chemistry, 2019-06-13)We investigate experimentally and model theoretically the mechanical behaviour of brain matter in torsion. Using a strain-controlled rheometer, we perform torsion tests on fresh porcine brain samples. We quantify the torque ... -
Prediction of Cell Culture Media Performance Using Fluorescence Spectroscopy
(2010)Cell culture media used in industrial mammalian cell culture are complex aqueous solutions that are inherently difficult to analyze comprehensively. The analysis of media quality and variance is of utmost importance in ... -

Prediction of pK(a) values of nido-carboranes by density functional theory methods
(American Chemical Society, 2006-08-25)A great parallel exists between metal complexes of cyclopentadienyl and arene ligands on one side and metal complexes of the nido derivatives of the icosahedral o-carborane clusters. With few exceptions, the metal complexation ... -
Predictive random graph ranking on the web
(2006)The incomplete information about the Web structure causes inaccurate results of various ranking algorithms. In this paper, we propose a solution to this problem by formulating a new framework called, Predictive Random Graph ...
