    PROMIS series. Volume 8: Midlatitude ground magnetograms

    Get PDF
    This is the eighth in a series of volumes pertaining to the Polar Region Outer Magnetosphere International Study (PROMIS). This volume contains 24 hour stack plots of 1-minute average, H and D component, ground magnetograms for the period March 10 through June 16, 1986. Nine midlatitude ground stations were selected from the UCLA magnetogram data base that was constructed from all available digitized magnetogram stations. The primary purpose of this publication is to allow users to define universal times and onset longitudes of magnetospheric substorms

    The American Dime Museum: Bodily Spectacle and Social Midways in Turn-of-the-Century American Literature and Culture

    The freak played a significant role in late-nineteenth- and early-twentieth-century entertainment, but its significance extended beyond such venues as sideshows and minstrel shows. This dissertation examines the freak as an avatar emblematic of several issues, such as class and race, traditionally focused on in studies of Turn-of-the Century American literature and culture. Disability and freakishness are explored as central to late-nineteenth- and early twentieth- century Americans’ identity. Freakishness is applied to a series of ways in which Americans in this period constructed their identity, including race, gender, and socioeconomic class, showing the dual role that the freak played for many white, able-bodied, upper-class American men. Freaks threatened such men’s sense of their own disability, triggering such complexes as Wounded Southernness or white masculinity. But contrasting themselves with freaks also solidified their visions of themselves as models of American normalcy. Besides freak shows, they encountered freakishness in a variety of arenas, including lynchings, slums, and early horror films. The late nineteenth and early twentieth century’s fascination with freakishness is situated as an outgrowth of that period’s eugenics movement, showing how the entwined concepts of eugenics and normalcy traversed ground that went much further than studies of physical aberration and chronic illness. This extended notion of the freak is discussed by analyzing various literary texts, especially the novels of William Dean Howells and Jack London. The autobiographies of Booker T. Washington and Helen Keller exemplify how double consciousness can serve as a means of enfreakment. Further, all these texts are situated culturally by medicalizing a series of historical events, including specific lynchings, as well as laws that reconfigured urban landscapes. The final chapter focuses on early horror film, arguing that film became the new American sideshow and in the process changed the definition of freak to something far more monstrous. In short, this dissertation demonstrates how the freak show pervaded America at the turn of the twentieth century and turned the country into one large dime museum

    Multiple crossings of a very thin plasma sheet in the Earth's magnetotail

    Get PDF
    High resolution magnetic field, plasma and energetic particle data from the IMP-8 spacecraft were studied for multiple crossings of the Earth's magnetotail plasma sheet when it becomes thin during magnetospheric substorms. Traversals recur on a time scale of several minutes and they are associated with high velocity plasma flows that are usually directed tailward but are occasionally directed earthward for brief intervals. Observations are explained by rapid oscillations of a plasma sheet that is only a few thousand km thick, a dimension comparable to the gyroradius of energetic protons. Differences in the angular distributions of the two energies indicate that the higher energy protons are preferentially located on field lines deeper in the tail lobe. A neutral line acceleration model is supported tailward streaming energetic electrons which are occasionally present at the lobe plasma sheet interface

    A putative fifth heterothallic species in Neurospora

    Get PDF
    Among Neurospora cultures sent to us by Daniel Le Pierres and Assienan Bernard from the vicinity of Abidjan, Ivory Coast, were two mixed cultures that made 8-spored asci when inoculated to synthetic crossing medium of Westergaard and Mitchell (1947) with filter paper as the only carbon source. Pure cultures of each mating type were obtained from conidial platings and were found to be sterile with all of the previously known species but highly fertile with some other Ivory Coast cultures (21 in addition to the first four). For all of these strains there has not been any mating reaction observed with N. sitophila or N. discreta, but it is barely possible to assign mating type from spot crosses on a lawn of N. crassa fl, and under optimum conditions there is sometimes formation of barren, unbeaked perithecia with N. intermedia. The new strains do not act as female parents on medium to which sucrose has been added

    Substitution of paper for sucrose can reverse apparent male sterility in Neurospora

    For many years we ascertained the species of newly collected Neurospora cultures by using them to fertilize standard species testers which had grown for five days on crossing medium with sucrose as the carbon source

    Neurospora strains incorporating fluffy, and their use as testers.

    We have used fluffy (fl) strains extensively as female parents in mating-type tests and for a variety of other applications where high fertility and absence of conidia are advantageous

    On the multispacecraft determination of periodic surface wave phase speeds and wavelengths

    Get PDF
    Observations of surface waves on the magnetopause indicate a wide range of phase velocities and wavelengths. Their multispacecraft analysis allows a more precise determination of wave characteristics than ever before and reveal shortcomings of approximations to the phase speed that take a predetermined fraction of the magnetosheath speed or the average flow velocity in the boundary layer. We show that time lags between two or more spacecraft can give a qualitative upper estimate, and we confirm the unreliability of flow approximations often used by analyzing a few cases. Using two‐point distant magnetic field observations and spectral analysis of the tailward magnetic field component, we propose an alternative method to estimate the wavelength and phase speed at a single spacecraft from a statistical fit to the data at the other site
