    Public poetry, memory, and the historical present: 1660-1745

    Public Poetry, Memory, and the Historical Present: 1660-1745 examines the role public poetry played in the fashioning of social memory during the so-called Augustan age of English literature; further, it traces in the rise and decline of public poetry during this period the emergence and subsequent estrangement of two distinctive modes of public memory: one highly emblematic and allusive in nature, fostering and indeed dependent upon a well-endowed collective sense of historical and literary tradition; the other far more literal and individualistic, fashioning social memory of the historical present--the present moment set against the backdrop of historical consciousness--by encouraging a personal awareness of the immediate, prosaic realities of the everyday world. Both modes of memory, the figurative and prosaic, were made broadly available to English society at large with the rise of public poetry in the years after the Restoration. They are generally united in the work of John Dryden, whose rise as a public figure coincides with the rise of public poetry itself in England, but it was the fate of Dryden\u27s greatest literary inheritor, Alexander Pope, to preside over--even accelerate--what one might call the divorce between the figurative and literal modes of public memory, the subsequent decline of the commercial appeal and cultural authority of formal verse, and the gradual eclipse of the figurative mode of public memory, which had tended to accommodate the habits of mind and memory inculcated by poetry. This divorce coincides with the gradual supplanting of occasional, journalistic poetry (broadsheet ballads as well as formal verse) by prose journalism and the novel, but also at work were the continuing shift from orality to literacy and an evolving sensibility--rationalist, individualist, and mercantilist in nature--in which the habit of emblematic allusion to a shared historical and literary tradition ceased to be relevant and viable. In tracing the broad cultural effects of an important poetic mode, therefore, I explore an important moment in the evolution of social consciousness, a moment that stands as the proximate origin of our own habits of memory

    Some Studies on Crystal and Molecular Structure

    The work which is described in this thesis is principally concerned with X-ray crystallography. Some other work, which Involved molecular orbital calculations, was also carried out and is described in Appendix I. Three compounds in all were studied by X-ray diffraction techniques, and the results of these investigations are summarised below. (1) Dimethylcertierocin: This compound, which has the formula CH3O.CO.(CH.CH)6.COOCH3, and which is the dimethyl ester of an acid isolated from a fungus, crystallises as yellow needles from chloroform. The crystals are triclinic, space goup C1 1 P 1 or C1 1 - P 1, and the unit cell dimensions are a = 9.06, b = 7.52, c = 6.07 A; alpha= 104.8, beta= 104.

    Deep level transient spectroscopy study for the development of ion-implanted silicon field-effect transistors for spin-dependent transport

    Full text link
    A deep level transient spectroscopy (DLTS) study of defects created by low-fluence, low-energy ion implantation for development of ion-implanted silicon field-effect transistors for spin-dependent transport experiments is presented. Standard annealing strategies are considered to activate the implanted dopants and repair the implantation damage in test metal-oxide-semiconductor (MOS) capacitors. Fixed oxide charge, interface trapped charge and the role of minority carriers in DLTS are investigated. A furnace anneal at 950 o\rm ^{o}C was found to activate the dopants but did not repair the implantation damage as efficiently as a 1000 o\rm ^{o}C rapid thermal anneal. No evidence of bulk traps was observed after either of these anneals. The ion- implanted spin-dependent transport device is shown to have expected characteristics using the processing strategy determined in this study.Comment: 4 pages, 6 figure

    Optical and electronic properties of sub-surface conducting layers in diamond created by MeV B-implantation at elevated temperatures

    Full text link
    Boron implantation with in-situ dynamic annealing is used to produce highly conductive sub-surface layers in type IIa (100) diamond plates for the search of a superconducting phase transition. Here we demonstrate that high-fluence MeV ion-implantation, at elevated temperatures avoids graphitization and can be used to achieve doping densities of 6 at.%. In order to quantify the diamond crystal damage associated with implantation Raman spectroscopy was performed, demonstrating high temperature annealing recovers the lattice. Additionally, low-temperature electronic transport measurements show evidence of charge carrier densities close to the metal-insulator-transition. After electronic characterization, secondary ion mass spectrometry was performed to map out the ion profile of the implanted plates. The analysis shows close agreement with the simulated ion-profile assuming scaling factors that take into account an average change in diamond density due to device fabrication. Finally, the data show that boron diffusion is negligible during the high temperature annealing process.Comment: 22 pages, 6 figures, submitted to JA

    The Scanopreg , an ultrasonic machine for diagnosing pregnancy in sheep, is effective as early as eight to nine weeks of pregnancy, and could therefore be a useful management tool

    Exploring the quality of the dying and death experience in the Emergency Department: An integrative literature review

    © 2018 Elsevier Ltd Aim: The aim of this integrative literature review was to explore the quality of the dying and death experience in the Emergency Department from the perspective of staff and carers. Background: Death in the Emergency Department is common. Understanding the quality of the death and dying experience of patients and their family members is crucial to building knowledge and improving care. Design: Systematic integrative literature review reported following the PRISMA guidelines. Data sources: Pubmed, Cumulative Index to Nursing and Allied Health Literature, Magonline (internurse), and the Cochrane library. Articles used were published in English during 1990- 2017. Review method: Appraisal and thematic analysis. Results: Sixteen articles are included. Eight themes emerged from the literature: care in the Emergency Department is about living not dying, staff perceive that death is a failure, staff feel underprepared to care for the dying patient and family in this environment, there is limited time for safe standards of care, staff stress and distress, staff use of distancing behaviours, the care of the dying role is devolved from medics to nurses at the end of life, and patients and staff perceive that the Emergency Department is not the preferred place of death Conclusion: There are areas of concern about end of life care in the Emergency Department. To improve practice and to ensure that a good death occurs, further research is needed. There is a need to understand more about the experience of caregivers when a relative or friend dies in the Emergency Department

    New results on heavy hadron spectroscopy with NRQCD

    We present results for the spectrum of b-bbar bound states in the quenched approximation for three different values of the lattice spacing. Results for spin-independent splittings are shown to have good scaling behaviour; spin-dependent splittings are more sensitive to discretisation effects. We discuss what needs to be done to match the experimental spectrum.Comment: 3 pages, contribution to Lattice'9
