    Poulton, Christopher John (University of St Andrews, 2008) - Thesis
    In this thesis, images of a debris disc are used to examine the evidence for the presence of a Neptune-like planet around ε Eridani and detections of protoplanetary discs are used to investigate the evidence for star and ...
  • EnzML : multi-label prediction of enzyme classes using InterPro signatures 

    De Ferrari, Luna; Aitken, Stuart; van Hemert, Jano; Goryanin, Igor (2012-04) - Journal article
    Background: Manual annotation of enzymatic functions cannot keep up with automatic genome sequencing. In this work we explore the capacity of InterPro sequence signatures to automatically predict enzymatic function. Results: ...

  • Enzyme immobilisation and catalysis in ordered mesoporous silica 

    Smith, Graham Murray (University of St Andrews, 2008-06-25) - Thesis
    A range of mesoporous materials based on SBA-15 have been prepared and characterised. The materials were templated by neutral block copolymer P123, and typically have a hexagonal (p6mm) pore structure, with high surface ...
  • Enzyme mechanism prediction : a template matching problem on InterPro signature subspaces 

    Mussa, Hamse Yussuf; De Ferrari, Luna; Mitchell, John B. O. (2015-12-03) - Journal article
    We recently reported that one may be able to predict with high accuracy the chemical mechanism of an enzyme by employing a simple pattern recognition approach: a k Nearest Neighbour rule with k=1 (k1NN) and 321 InterPro ...
  • Ephedrine requirements are reduced during spinal anaesthesia for caesarean section in preeclampsia 

    Clark, V. A.; Sharwood-Smith, Geoffrey H.; Stewart, A. V. G. (Elsevier Ltd., 2005-01) - Journal article
    Background: Despite controversy over the haemodynamically safest blockade for caesarean section in women with severe preeclampsia, an increasing number of anaesthetists now opt for spinal anaesthesia. In a previous study ...
  • Epiclesis: a way of life 

    Hamilton, Roddy (St Mary's College, University of St Andrews, 2008-12-01) - Journal article
    The epiclesis is that part of the prayer of consecration of the Eucharistic elements by which the Holy Spirit is invoked. Roddy Hamilton's essay raises some very thought-provoking questions about what is going on at this ...
  • Epidemic events : state-formation, class struggle and biopolitics in three epidemic crises of modern China 

    Lynteris, Christos (University of St Andrews, 2010-06-25) - Thesis
    Based on extended research on Chinese medical and epidemiological archival material dating back to the beginning of the 20th century, and on six months of internship in epidemiology in Beijing’s Medical School and in Haidian ...
  • The epidemiology of Phytophthora ramorum and P. kernoviae at two outbreak sites in Scotland 

    Elliot, Matthew (University of St Andrews, 2013-09-18) - Thesis
    This PhD examined the epidemiology of two potentially devastating plant pathogens, Phytophthora ramorum and P. kernoviae, at Benmore Botanic Garden in Argyll & Bute and Brodick Castle Garden in Arran. Spore traps, river ...
  • Epidermal growth factor signalling controls Myosin II planar polarity to orchestrate convergent extension movements during Drosophila tubulogenesis 

    Saxena, Aditya; Denholm, Barry; Bunt, Stephanie; Bischoff, Marcus; VijayRaghavan, Krishnaswamy; Skaer, Helen (2014-12-02) - Journal article
    Most epithelial tubes arise as small buds and elongate by regulated morphogenetic processes including oriented cell division, cell rearrangements, and changes in cell shape. Through live analysis of Drosophila renal tubule ...
  • The epistemic province of photography 

    De Asis, Ines Nicole Echevarria (University of St Andrews, 2016-06-23) - Thesis
    This thesis argues that photographs enhance the repertoire of seeing the way eyeglasses, microscopes and telescopes do. This kinship is based on these devices sharing a feature called transparency. Transparent devices ...
  • Epistemic theories of democracy, constitutionalism and the procedural legitimacy of fundamental rights 

    Allard-Tremblay, Yann (University of St Andrews, 2012-11-30) - Thesis
    The overall aim of this thesis is to assess the legitimacy of constitutional laws and bills of rights within the framework of procedural epistemic democracy. The thesis is divided into three sections. In the first section, ...
