Computations for Coxeter arrangements and Solomon's descent algebra III: Groups of rank seven and eight
(Elsevier, 2014-11-06)In this paper we extend the computations in parts I and II of this series of papers and complete the proof of a conjecture of Lehrer and Solomon expressing the character of a finite Coxeter group W acting on the p-th graded ... -
Computations for Coxeter arrangements and Solomon's descent algebra: Groups of rank three and four
(Elsevier, 2012-06-03)In recent papers we have refined a conjecture of Lehrer and Solomon expressing the characters of a finite Coxeter group W afforded by the homogeneous components of its Orlik-Solomon algebra as sums of characters induced ... -
Computing the table of marks of a cyclic extension
(American Mathematical Society, 2012-02-24)The subgroup pattern of a finite group C is the table of marks of G together with a list of representatives of the conjugacy classes of subgroups of G. In this article we present an algorithm for the computation of the ... -
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 ... -
Concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) in human milk from Ireland: temporal trends and implications for nursing infant exposure
(OAE Publishing Inc, 2021-11-19)Aim: The elucidation of temporal trends in human exposure to polychlorinated biphenyls (PCBs) and 17 polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) since the previous Irish human milk surveys and to evaluate the ... -
Conformations of myoglobin-derived peptides at the air-water interface
(NUI Galway, 2016-12-12)Simulation files, analysis scripts, and output data to accompany article: Cheung, David L. (2016). Conformations of Myoglobin-Derived Peptides at the Air–Water Interface. Langmuir, 32(18), 4405-4414. doi: 10.1021/acs.la ... -
Conformations of myoglobin-derived peptides at the air-water interface
(American Chemical Society, 2016-04-14)The conformational change exhibited by proteins at liquid interfaces, such as the air-water and oil-water interfaces, has long been of interest, both for understanding protein structure outside of native environments and ... -
A connection between star formation activity and cosmic rays in the starburst galaxy M 82
(2009)Although Galactic cosmic rays (protons and nuclei) are widely believed to be dominantly accelerated by the winds and supernovae of massive stars, definitive evidence of this origin remains elusive nearly a century after ... -
Continuous culture of Escherichia coli, under selective pressure by a novel antimicrobial complex, does not result in development of resistance
(Nature Research, 2019-02-20)We attempted to generate de novo resistance to a newly described biocidal complex, ITC (iodo-thiocyanate complex), and to levofloxacin (LVX) in Escherichia coli ATCC 25922, by means of selective chemostat culture. We ... -
Contrasting responses to nutrient enrichment of prokaryotic communities collected from deep sea sites in the Southern Ocean
(MDPI Open-Access Journals, 2013-09-13)Abstract: Deep water samples (ca. 4,200 m) were taken from two hydrologically-similar sites around the Crozet islands with highly contrasting surface water productivities. Site M5 was characteristic of high productivity ... -
Control of transfer and weak closure in fusion systems
(2010)We show that K¿ and K¿ control transfer in every fusion system on a finite p-group when p ¿ 5, and that they control weak closure of elements in every fusion system on a finite p-group when p ¿ 3. This generalizes resultsof ... -
Controlling the pirouetting motion in rotaxanes by counterion exchange
(American Chemical Society, 2014-07-25)A fine control of the pirouetting motion of rotaxanes was achieved by using a series of metallabisdicarbollides. The latter were used as anions in the protonated form of benzylic amide macrocycle-containing fumaramide ... -
A convenient synthetic route to useful monobranched polyethoxylated halogen terminated [3,3 -Co(1,2-C2B9H11)2]- synthons
(Royal Society of Chemistry, 2009-11-15)An atom efficient and environmentally friendly route has been developed to obtain a new range of reagents in metallacarborane chemistry having monobranched polyethoxylated cobaltabisdicarbollide synthons. -
Conversion of gel-forming crystal needles to easily processable more equant crystals Using high-shear ultralow attrition agitation: accelerated Ostwald ripening without crystal attrition
(American Chemical Society, 2019-02-01)We demonstrate the first examples of the transformation of gel-forming crystal needles into easily processable more equant crystals by accelerated Ostwald ripening without detectable crystal attrition. Using high solution ... -
