A critical edition of Derek Walcott's Omeros
No full textThe thesis is a Critical Edition of Derek Walcott’s Omeros, consisting of a Critical
Introduction and Annotations. The Critical Introduction analyses:
- Narrative
- Settings
- Metaphor and Paronomasia
- Symbolism
- Historiography
- Intertexts
- Dualism
- Autobiography
- Dialects
- Prosody.
The Annotations comment on more than 1000 references that may be obscure and on
specifics of narrative, language and prosody.
This study presents new conclusions about some aspects of Omeros:
- It challenges the prevailing view that the work is written substantially in a
variation of terza rima and shows that regular quatrains predominate.
- It demonstrates ways in which the metrics follow the sense of the narrative and
takes a more balanced position on the use of Caribbean as opposed to classical
metrics than that put forward previously.
- It identifies a paragraphic structure to the verse.
- It proposes a new prosodic structure for the significant Chapter XXX/iii.
- It extends Walcott’s recognised use of numerology into word counting the
names of characters.
- It develops the idea of Walcott’s dualism and his use of pairing and
contradiction as a dialectical method.
- It defines his wide use of paronomasia and shows that many of the puns have a
metaphorical aspect beyond mere word-play.
- It analyses some of Walcott’s symbolism.
- It identifies intertextual links to his earlier works and to some thirty other
writers, and suggests homage to Hemingway and possibly Heaney.
- It provides the first complete analysis of Walcott’s rhyme types in Omeros.
In its analysis of Omeros and in the Annotations it has included commentary from
across the critical literature, to provide some sense of other views on Walcott’s
writing, and has included as many as possible of Walcott’s own comments on Omeros
and on the writer’s task, as a background to understanding the poem
Yeast metabolism in fresh and frozen dough : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Food Technology at Massey University, Palmerston North, New Zealand
No full textAuthor also known as SM LovedayFresh bakery products have a very short shelf life, which limits the extent to which manufacturing can be centralised. Frozen doughs are relatively stable and can be manufactured in large volumes, distributed and baked on-demand at the point of sale or consumption. With appropriate formulation and processing a shelf life of several months can be achieved.Shelf life is limited by a decline in proofing rate after thawing, which is attributed to a) the dough losing its ability to retain gas and b) insufficient gas production, i.e. yeast activity. The loss of shelf life is accelerated by delays between mixing and freezing, which allow yeast cells the chance to ferment carbohydrates.This work examined the reasons for insufficient gas production after thawing frozen dough and the effect of pre-freezing fermentation on shelf life. Literature data on yeast metabolite dynamics in fermenting dough were incomplete. In particular there were few data on the accumulation of ethanol, a major fermentation end product which can be injurious to yeast.Doughs were prepared in a domestic breadmaker using compressed yeast from a local manufacturer and analysed for glucose, fructose, sucrose, maltose and ethanol. Gas production after thawing declined within 48 hours of frozen storage. This was accelerated by 30 or 90 minutes of fermentation at 30;C prior to freezing.Sucrose was rapidly hydrolysed and yeast consumed glucose in preference to fructose. Maltose was not consumed while other sugars remained. Ethanol, accumulated from consumption of glucose and fructose, was produced in approximately equal amounts to CO2, indicating that yeast cells metabolised reductively.Glucose uptake in fermenting dough followed simple hyperbolic kinetics and fructose uptake was competitively inhibited by glucose. Mathematical modelling indicated that diffusion of sugars and ethanol in dough occurred quickly enough to eliminate solute gradients brought about by yeast metabolism
Tilting at Windmills : BLDSC and the UK Higher Education Community
No full textPurpose - To provide an overview of, the relationship between the British Library and higher education libraries in the 1990s, with particular relation to document supply. It also goes on to explore current developments in scholarly communication. Design/methodology/approach - The author played a role in several of the events described and uses the available literature to enlarge on a personal view of that decade. Findings - The paper shows that the relationship was a strained one caused in part by a mismatch of resources, but is in any case dwarfed by the larger external forces and changing opportunities and technologies for scholarly communication. Originality/value - Provides a record of the period
A functional characterization of CGI-58
No full textMutations in the gene CGI-58/ABHD5 cause Chanarin-Dorfman Syndrome, a Neutral Lipid Storage Disorder (NLSD) where many cells and tissues, including human skin fibroblasts, store excessive triacylglycerol (TAG). The protein, CGI‐58, has been characterized in vitro as both a co‐activator of adipose triglyceride lipase (ATGL) and a lysophosphatidic acid acyltransferase (LPAAT). We hypothesized that CGI‐58 LPAAT activity is not necessary for co-activation of ATGL. This hypothesis was investigated through 3 specific aims: 1) to identify LPAAT active site residues, 2) to demonstrate that CGI‐58 lacking LPAAT activity can co-activate ATGL, and 3) to analyze the lipid composition of cultured NLSD fibroblasts relative to normal human skin fibroblasts. A molecular model of CGI‐58 was created to identify potential active site residues. In the model, the putative LPAAT active site residues H329 and D334 were not in close proximity, suggesting that they may not be active site residues. Recombinant H329A and D334A CGI‐58 variants, when purified from BL21(DE3) E. coli, showed higher levels of LPAAT activity than purified wild-type CGI‐58. LPAAT activity was linked to a protein contaminant, likely plsC, the endogenous E. coli LPAAT. The purification of recombinant CGI‐58 was optimized to reduce contaminant proteins. These new preparations lacked LPAAT activity, yet retained the ability to co‐activate ATGL. Additionally, extracts of Bl21(DE3) cells expressing GST-tagged CGI‐58 lacked LPAAT activity when plsC was removed by centrifugation. The previously observed LPAAT activity was due to a protein contaminant; thus, CGI‐58 lacks LPAAT activity and LPAAT activity is not necessary for the co-activation of ATGL. Additionally, using a protein‐lipid overlay, CGI‐58 bound to phosphatidylinositol 3-phosphate [PI(3)P] and phosphatidylinositol 5-phosphate [PI(5)P] but not lysophosphatidic acid [LPA], the LPAAT substrate. CGI‐58 binding of PI(3)P or PI(5)P does not alter co-activation of ATGL. Finally, CGI-58 variant H84R, found in humans with NLSDi, was expressed in cultured NLSD cells and studied in vitro. H84R CGI-58 failed to reduce accumulated TAG of NLSD fibroblasts, unlike unmodified CGI-58 or the H84A variant. Both H84 variants lacked the ability to co-activate ATGL in vitro. Thus, H84R CGI‐58 contributes to the NLSD phenotype by failing to co-activate ATGL.Ph. D.Includes bibliographical referencesby Derek B. McMaho
A review of the fundamentals of the finite element simulation of metal cutting
No full textMetal cutting is one of the most widely-used manufacturing processes. Finite element simulation of this process has matured enough to give valuable insight of this process and, sometimes, good agreement with experiment. However, due to the complex nature of the metal cutting process, finite element simulation of metal cutting is not straightforward. This paper reviews the fundamentals of the finite element simulation of metal cutting. It also includes some significant advancements and applications reported recently. Conclusions and comments on future research are also presented. This paper contributes by helping to establish comprehensive knowledge about the finite element simulation of metal cutting and the state-of-the-art knowledge in this field
The Significance of Socio-genetic Understanding: Response to Fowler
No full textThe following article is a published response to a review of On Bourdieu, Education and Society (Fowler, B (2006) ‘Clashing Interpretations of Bourdieu's Theory of Practice: Derek Robbins, On Bourdieu, Education and Society. Oxford: Bardwell Press, 2006. ISBN 0_9548_6836_6’ Journal of Classical Sociology 2007; 7 (3) 367) by Derek Robbins, the original author. In this response Robbins criticises the tendency amongst social scientists to advocate the exploitation of biographical material without challenging the detached superiority of scientific professional. He reasserts the need to develop a sociology of ‘life-world interaction’ but accepts that it must not concentrate on the interpersonal to the neglect of an objective perspective especially concerning conditions of disadvantage and inequality
Positron-annihilation study of equilibrium defects in Al-Cu-Fe face-centered-icosahedral quasicrystals
No full textIn situ Doppler-broadening temperature scans and room temperature positron-lifetime measurements are reported for Al63CU25Fe12, Al62.5CU25Fe12.5, Al62CU25.5Fe12.5, and Al62Cu22.8Fe15.2 face-centered-icosahedral (FCI) quasicrystalline samples. Quenched-in disorder has been observed and found to anneal out of the samples above 200 degrees C. A quasicrystal-to-microcrystal phase transition has been observed in two of the samples (Al63Cu25Fe12 and Al62Cu22.8Fe15.2), indicating an instability of the FCI phase at low temperatures. No such transition is observed in the other two samples (Al62.5CU25Fe12.5 and Al62Cu25.5Fe12.5). It is shown that intrinsic structural vacancies, possessing only Al-atom nearest neighbors, exist in both the microcrystal and FCI phases and act as saturation traps for the positrons. At similar to 200 degrees C, thermal activation of dynamic Al-atom phasons in the FCI phase results in distortions of the intrinsic structural vacancies as the nearest neighbor Al atoms begin to hop within double-well potentials. At higher temperatures (525-750 degrees C depending upon the sample stoichiometry) dynamic Cu-atom phasons are activated and observed to coincide with the onset of plasticity in the FCI phase.PT: J; CR: AUDIER M, 1986, PHILOS MAG B, V54, L105 AUDIER M, 1991, PHILOS MAG B, V63, P1375 AUDIER M, 1993, J NON-CRYST SOLIDS, V153, P591 BELIN E, 1993, J NONCRYST SOLIDS, V153, P298 BELLISSENT R, 1993, J NON-CRYST SOLIDS, V153, P1 BESSIERE M, 1991, J PHYS I, V1, P1823 BRESSON L, 1993, J NONCRYST SOLIDS, V153, P468 BURKOV SE, 1992, J PHYS-CONDENS MAT, V4, P9447 CALVAYRAC Y, 1990, J PHYS-PARIS, V51, P417 CHIDAMBARAM R, 1990, B AM PHYS SOC, V35, P331 CHIDAMBARAM R, 1990, J PHYS-CONDENS MAT, V2, P251 CHIDAMBARAM R, 1990, J PHYS-CONDENS MAT, V2, P9941 CHIDAMBARAM R, 1993, PHYS REV B, V48, P3030 CODDENS G, 1991, EUROPHYS LETT, V16, P271 CODDENS G, 1993, EUROPHYS LETT, V154, P557 CODDENS G, 1993, EUROPHYS LETT, V23, P33 CORNIERQUIQUAND.M, 1993, J NONCRYST SOLIDS, V154, P10 DENOYER F, 1990, J PHYS-PARIS, V51, P651 DENOYER F, 1993, J NON-CRYST SOLIDS, V153, P595 DIVINCENZO DP, 1993, J NONCRYST SOL, V153, P145 DUNLAP RA, 1987, J PHYS F MET PHYS, V17, L39 ELSER V, 1985, PHYS REV LETT, V55, P2883 HABERKERN R, 1993, J NON-CRYST SOLIDS, V153, P303 HAUTOJARVI P, 1977, PHILOS MAG, V35, P973 HOWELL RH, 1992, MATER SCI FORUM, V105, P651 ISHIMASA T, 1990, PHIL MAG LETT, V62, P357 JANOT C, 1991, EUROPHYS LETT, V14, P355 KAN XB, 1993, J NON-CRYST SOLIDS, V153, P33 KANAZAWA I, 1990, J NON-CRYST SOLIDS, V117, P793 KANAZAWA I, 1992, MATER SCI FORUM, V105, P1093 KANG SS, 1992, PHILOS MAG A, V66, P151 KATZ A, 1991, PHYS REV B, V44, P2071 KIRKEGAARD P, 1974, COMPUT PHYS COMMUN, V7, P401 KIZUKA T, 1989, PHYS REV B, V40, P796 KLEIN T, 1991, PHYS REV LETT, V66, P2907 KLEIN T, 1993, J NON-CRYST SOLIDS, V153, P312 KLEIN T, 1993, J NON-CRYST SOLIDS, V153, P562 KOSTER U, 1993, J NONCRYST SOLIDS, V153, P446 KRISTIAKOVA K, 1992, MATER SCI FORUM, V105, P1113 LAWTHER DW, 1990, J PHYS-CONDENS MAT, V2, P6239 LAWTHER DW, 1993, J NONCRYST SOLIDS, V154, P611 LAWTHER DW, 1993, KEY ENG MATER, V81, P95 LINDQVIST P, 1993, PHYS REV B, V48, P630 MOTSCH T, 1992, J PHYS I, V2, P861 NIEMINEN RM, 1983, POSITRON SOLID STATE, P359 OHATA T, 1990, PHYS REV B, V42, P6730 PAULING L, 1938, PHYS REV, V54, P899 PIERCE FS, 1993, PHYS REV B, V47, P5670 POON SJ, 1992, ADV PHYS, V41, P303 QUILICHINI M, 1993, J NONCRYST SOLIDS, V153, P568 QUIVY A, 1993, J NONCRYST SOLIDS, V153, P482 SADOC A, 1993, J NONCRYST SOLIDS, V153, P338 SAHNOUNE A, 1993, J NONCRYST SOLIDS, V153, P343 SANYAL MK, 1989, J PHYS-CONDENS MATT, V1, P3733 SEEGER A, 1987, PHYS STATUS SOLIDI A, V102, P171 SEEGER A, 1989, POSITRON ANNIHILATIO, P275 SHASTRI A, 1993, J NON-CRYST SOLIDS, V153, P347 SHI D, 1992, MATER SCI FORUM, V110, P829 SHIELD JE, 1992, PHYSICS CHEM FINITE, V1, P125 STEPHENS PW, 1986, PHYS REV LETT, V56, P1168 TSAI AP, 1987, J MATER SCI LETT, V6, P1403 TSAI AP, 1990, PHIL MAG LETT, V61, P9 WANG K, 1993, J NONCRYST SOLIDS, V153, P357 WASEDA A, 1993, J NON-CRYST SOLIDS, V153, P635; NR: 64; TC: 17; J9: PHYS REV B; PG: 7; GA: MW349Source type: Electronic(1

Traduciendo la historia : Omeros, de Derek Walcott
No full textResumen: Omeros, extensa obra en verso en inglés publicada en 1990, fue escrita por Derek Walcott, nacido en la isla de Santa Lucía. Poco después la obra literaria de Walcott fue reconocida con el Nobel de Literatura (1992). Los versos de Omeros constituyen para diversos estudiosos una amplia meditación sobre la historia —que involucra a América, Europa, África y Asia—; sin embargo, desde el punto de vista de los estudios de traducción, podríamos afirmar que este poema épico es un intento del poeta por «traducir-se» en esta propuesta de (re)construcción de la historia y la memoria de un pueblo y, a la vez, de sí. El autor, con destreza, toma los elementos dispares de un entorno social para dotar de una voz singular, formada por voces entremezcladas, a la re-visión de la construcción del Nuevo Mundo.Abstract: Omeros, a long poem published in 1990 in English, was written by St. Lucian-born writer Derek Walcott. Shortly after this book appeared, the Nobel Prize for Literature recognized his contributions (1992). For some authors, the verses that make up Omeros constitute a long meditation on history, a history that involves America, Europe, Africa and Asia. However, translation studies may see this epic poem as an attempt on the part of the poet to translate himself in the lines, a proposal for re-constructing the history and memory of a people and, in turn, of himself. The author has skillfully managed to intertwine different elements of his social milieu to provide readers with a re-vision of the New World uttered in a unique voice, made up of a chorus
