Homocysteine toxicity in escherichia coli is caused by a perturbation of branched-chain amino acid biosynthesis
(American Society for Microbiology, 2005-06-20)In Escherichia coli the sulfur-containing amino acid homocysteine (Hcy) is the last intermediate on the methionine hiosynthetic pathway. Supplementation of a glucose-based minimal medium with Hcy at concentrations greater ... -
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
(2011)We reveal a correspondence between the homological torsion of the Bianchi groups and new geometric invariants, which are effectively computable thanks to their action on hyperbolic space. We use it to explicitly compute ... -
Homology of some artin and twisted artin groups
(Cambridge University Press (CUP), 2009-09-21)We begin the paper with a simple formula for the second integral homology of a range of Artin groups. The formula is derived from a polytopal classifying space. We then introduce the notion of a twisted Artin group and ... -
Homomorphisms between mapping class groups
(Mathematical Sciences Publishers, 2012-12-31)Suppose that X and Y are surfaces of finite topological type, where X has genus g >= 6 and Y has genus at most 2g - 1; in addition, suppose that Y is not closed if it has genus 2g - 1. Our main result asserts that ... -
Homotopical aspects of lie algebras
(Cambridge University Press (CUP), 1993-06-01)The Hurewicz theorem, Mayer-Vietoris sequence, and Whitehead's certain exact sequence are proved for simplicial Lie algebras. These results are applied, using crossed module techniques, to obtain information on the low ... -
Homotopy and normalization properties for admissible maps

Homotopy invariant results on complete gauge spaces
(Cambridge University Press (CUP), 2003-04-01)A fixed point theorem and two homotopy invariant results axe presented for generalised contractive maps defined on complete gauge spaces. -

Hooked on science
(EIROforum, 2017-03-27)In this article, Martin McHugh and Veronica McCauley present a modern and interesting way to get students more engaged during lessons. They describe a detailed procedure that can be followed by any teacher or adapted to ... -
Hooking up as a sexual script: How is consent to sexual activity communicated in an emerging adult university population when mediated by gender and alcohol in the context of societal and cultural norms?
(NUI Galway, 2022-04-25)This thesis presents a mixed-methods study to examine how consent to sexual activity is understood and communicated by Irish college men and women. Additionally, it seeks to examine how injunctive and descriptive norms ... -
Hopf algebra structure of continual virasoro algebra deformations
(IOP Publishing, 2013-01-28)The Hopf algebra structure of a few parametric deformations of the continual Virasoro algebra is proven. -

Horror, hurling, and Bertie: aspects of contemporary Irish horror cinema
(University of Waterloo, Department of Fine Arts (Film Studies), 2012)In Ireland, generic international cinematic forms have provided an important means through which filmmakers have attempted to tell Irish stories while engaging international audiences. However, in general Irish filmmakers ... -

Hospital tests and patient related factors influencing time-to-theatre in 1000 cases of suspected appendicitis: a cohort study
(Springer Nature, 2015-01-01)Background: Acute appendicitis is increasingly being managed in the setting of a dedicated emergency theatre. However understanding of hospital factors that influence time-to-theatre (TTT) is poor. Thus, the aim of this ...
