    Shakespeare, Sidney, and Spenser in an Early Continental Library

    Get PDF
    This article presents an account of a hitherto unpublished library list in the Bibliothàque nationale de France: MS fr. 4188. The list, preceded by an inventory of mathematical instruments, provides entries for a little under 1,000 books of poetry, theology, philosophy, history, antiquarianism, mathematics, and the trivial arts, published between 1474 and 1621. The entries are distinguished by a high degree of bibliographical detail, including information about the books’ bindings. Dominated by Latin imprints, the library also includes a number of titles in French (the probable nationality of the owner) and English, including works by Shakespeare, Spenser and Sidney. It constitutes very early—perhaps the earliest—evidence for continental ownership of Shakespeare's poems The Rape of Lucrece and Venus and Adonis. The English works are discussed in relation to the other learned interests of the owner, whose identity, profession and confession are speculated upon.This is the author accepted manuscript.

    Those Olden Golden Days

    [Verse 1] Most ev’ry body in the city Comes from some little town, They say They’re glad they left the village Glad cause they been around But deep in they’re hearts a mem’ry say of Good old Fashion Way’s. [Chpurs] Olden days, Golden days, Let me dream of old familiar ways, Church bells ring Choirs sing Same old lovers lane and Ev’rything Mother’s knee calling me Millions couldn’t buy that memory, More and more, I’m yearning for, Those Olden Golden days [Verse 2] When first we came down to the city Said goodbye to the farm, Bright lights and city folks around us Seem like a magic charm But after a while our mem’ry roams to Dear old Home sweet Home; [Chorus

    Inventions Utilizing Microfluidics and Colloidal Particles

    Several related inventions pertain to families of devices that utilize microfluidics and/or colloidal particles to obtain useful physical effects. The families of devices can be summarized as follows: (1) Microfluidic pumps and/or valves wherein colloidal-size particles driven by electrical, magnetic, or optical fields serve as the principal moving parts that propel and/or direct the affected flows. (2) Devices that are similar to the aforementioned pumps and/or valves except that they are used to manipulate light instead of fluids. The colloidal particles in these devices are substantially constrained to move in a plane and are driven to spatially order them into arrays that function, variously, as waveguides, filters, or switches for optical signals. (3) Devices wherein the ultra-laminar nature of microfluidic flows is exploited to effect separation, sorting, or filtering of colloidal particles or biological cells in suspension. (4) Devices wherein a combination of confinement and applied electrical and/or optical fields forces the colloidal particles to become arranged into three-dimensional crystal lattices. Control of the colloidal crystalline structures could be exploited to control diffraction of light. (5) Microfluidic devices, incorporating fluid waveguides, wherein switching of flows among different paths would be accompanied by switching of optical signals

    Evaluating invasion risk for freshwater fishes in South Africa

    South Africa, as a signatory of the Convention on Biological Diversity, has an obligation to identify, prioritise and manage invasive species and their introduction pathways. However, this requires knowledge of the introduction pathways, factors influencing establishment success, invasive potential, current distributions and ecological impacts. Objectives: To evaluate the Fish Invasiveness Screening Kit (FISK) to predict the invasion risk posed by fish species proposed for introduction into South Africa. Method: FISK assessments were compiled for species whose invasion status in South Africa was known. A Receiver operating characteristic (ROC) analysis was conducted to calibrate the FISK for South Africa. The calibrated FISK was used to evaluate the risk that three species recently proposed for importation for aquaculture could become invasive in South Africa. Results: A FISK score of 14 was identified as the threshold to delineate between species that could become invasive in South Africa and those that are unlikely to become invasive. Of the three species evaluated, Silurus glanis had a high risk of becoming invasive in South Africa, Lates calcarifer was likely to be invasive and Oncorhynchus tshawytscha was unlikely to be invasive in South Africa. Conclusion: FISK was demonstrated to be a useful risk assessment tool to evaluate the invasion risk posed by species proposed for use in aquaculture. For the large number of fish imported for the pet trade, a rapid screening assessment to flag potentially high risk species was recommended prior to a full FISK assessment for flagged species.EM201
