Console and Keyboard Melodies Broadcast from the Bangor Sportsmen\u27s Show

Irving Hunter announces as Norm Lambert takes requests for songs to play on their show Console and Keyboard Melodies in a special, live broadcast from the Bangor Sportsmen\u27s Show at the Bangor Auditorium March 18, 1949. Hunter speaks briefly with several show attendees and organizers, including Carl Lowe of the Thomas Rod Company, Maine Fisheries Warden Lester Stubbs, Mrs. George Wilson of Newport, Chief Crazy Bull, and Show Manager Howard Bond. The original WLBZ station log indicated that this was the first use of the station\u27s new roving microphone at the Bangor Auditorium.https://digitalcommons.library.umaine.edu/wlbz_station_records/1063/thumbnail.jp

Global literary journalism: exploring the journalistic imagination

Global Literary Journalism: Exploring the Journalistic Imagination (Peter Lang, of New York) brings together the writings of 22 academics focusing on literary journalism in a wide range of countries and regions including Canada, Finland, India, Ireland, Poland, Sweden, Latin America, the UK, the United States and the Middle East. The University of Lincoln is well represented: Jane Chapman, Professor of Communications, focuses on the journalism of Arundhati Roy, Rupert Hildyard, Principal Lecturer in English, writes on John Lanchester, Nick Nuttall examines the gonzo writings of Hunter S. Thompson, PhD student Florian Zollmann delves into the John Pilger archives, while another PhD student, Anna Hoyles, explores the early journalism of Moa Martinson. Rod Whiting looks critically at Ernest Hemingway’s career as a journalist – while John Tulloch’s chapter on Gordon Burn is titled ‘Journalism as a Novel: The Novel as Journalism’ and Richard Keeble writes on the war reporting of the Independent’s award-winning Robert Fisk. The final chapter, by Susan Greenberg, of Roehampton University, and titled ‘Slow Journalism in the Digital Fast Lane’ examines literary journalism in the age of the internet

'Fire hardening' spear wood does slightly harden it, but makes it much weaker and more brittle

It is usually assumed that 'fire hardening' the tips of spears, as practised by hunter-gatherers and early Homo spp., makes them harder and better suited for hunting. This suggestion was tested by subjecting coppiced poles of hazel to a fire-hardening process and comparing their mechanical properties to those of naturally seasoned poles. A Shore D hardness test showed that fire treatment slightly increased the hardness of the wood, but flexural and impact tests showed that it reduced the strength and work of fracture by 30% and 36%, respectively. These results suggest that though potentially slightly sharper and more durable, fire-hardened tips would actually be more likely to break off when used, as may have been the case with the earliest known wooden tool, the Clacton spear. Fire might first have been used to help sharpen the tips of spears, and fire-hardening would have been a mostly negative side effect, not its primary purpose

Solitary waves on a ferrofluid jet

The propagation of axisymmetric solitary waves on the surface of an otherwise cylindrical ferrofluid jet subjected to a magnetic field is investigated. An azimuthal magnetic field is generated by an electric current flowing along a stationary metal rod which is mounted along the axis of the moving jet. A numerical method is used to compute fully-nonlinear travelling solitary waves and predictions of elevation waves and depression waves by Rannacher & Engel (2006) using a weakly-nonlinear theory are confirmed in the appropriate ranges of the magnetic Bond number. New nonlinear branches of solitary wave solutions are identified. As the Bond number is varied, the solitary wave profiles may approach a limiting configuration with a trapped toroidal-shaped bubble, or they may approach a static wave (i.e. one with zero phase speed). For a sufficiently large axial rod, the limiting profile may exhibit a cusp

Euler equations on homogeneous spaces and Virasoro orbits

We show that the following three systems related to various hydrodynamical approximations: the Korteweg--de Vries equation, the Camassa--Holm equation, and the Hunter--Saxton equation, have the same symmetry group and similar bihamiltonian structures. It turns out that their configuration space is the Virasoro group and all three dynamical systems can be regarded as equations of the geodesic flow associated to different right-invariant metrics on this group or on appropriate homogeneous spaces. In particular, we describe how Arnold's approach to the Euler equations as geodesic flows of one-sided invariant metrics extends from Lie groups to homogeneous spaces. We also show that the above three cases describe all generic bihamiltonian systems which are related to the Virasoro group and can be integrated by the translation argument principle: they correspond precisely to the three different types of generic Virasoro orbits.Comment: 26 pages, 4 figures, LaTeX.

Noninvasive imaging of the thirteen-lined ground squirrel photoreceptor mosaic.

Ground squirrels are an increasingly important model for studying visual processing, retinal circuitry, and cone photoreceptor function. Here, we demonstrate that the photoreceptor mosaic can be longitudinally imaged noninvasively in the 13-lined ground squirrel (Ictidomys tridecemlineatus) using confocal and nonconfocal split-detection adaptive optics scanning ophthalmoscopy using 790 nm light. Photoreceptor density, spacing, and Voronoi analysis are consistent with that of the human cone mosaic. The high imaging success rate and consistent image quality in this study reinforce the ground squirrel as a practical model to aid drug discovery and testing through longitudinal imaging on the cellular scale

Femtosecond x-ray diffraction from an aerosolized beam of protein nanocrystals

We demonstrate near-atomic-resolution Bragg diffraction from aerosolized single granulovirus crystals using an x-ray free-electron laser. The form of the aerosol injector is nearly identical to conventional liquid-microjet nozzles, but the x-ray-scattering background is reduced by several orders of magnitude by the use of helium carrier gas rather than liquid. This approach provides a route to study the weak diffuse or lattice-transform signal arising from small crystals. The high speed of the particles is particularly well suited to upcoming MHz-repetition-rate x-ray free-electron lasers
