    The Nimbus 4 IRLS meteorological experiment

    The Nimbus 4 interrogation, recording, and location system is designed to locate and collect measurement data of upper atmospheric parameters through the tracking of free floating, constant level balloons flying at altitudes of 20.5 and 24.1 km and carrying specially designed interrogation packages. The basic elements of the system include a ground acquisition and command station, the Nimbus satellite, and the remote sensing platforms. Addresses of platforms as they come into view are programmed into the satellite on an orbit by orbit basis from the central ground station. Sensory data are transmitted to the satellite for storage and readout from balloon interrogation units

    The advantages of a technique in which data collection platforms randomly transmit signal to a polar orbiting satellite, thus eliminating satellite interrogation are demonstrated in investigations of the atmosphere; oceanographic parameters; Arctic regions and ice conditions; navigation and position location; and data buoy development

    Satellite and ground radiotracking of elk

    Get PDF
    Radiotracking and monitoring of free-living animals in natural environments is providing an effective new technique for acquiring information on biological processes, including animal orientation and navigation. To test the practicability of extending the technique by using satellite systems for tracking animals, a female elk was instrumented with an electronic collar. It contained both the Interrogation Recording Location System (IRLS) transponder and a Craighead-Varney ground-tracking transmitter. The elk was successfully tracked and monitored by satellite during month of April 1970. This was the first time an animal had been tracked by satellite on the surface of the earth

    Changing the Core: Redefining Gaming Culture from a Female-Centered Perspective.

    Full text link
    In the mid-2000s, the spread of casual, social, and mobile games led researchers, journalists, and players to believe that video gaming was opening up to previously marginalized audiences, especially women. At the same time, game culture has seen a significant increase in incidents of sexism and misogyny. This dissertation uses a critical exploration of industry texts and practices, as well as interviews with thirty-seven female gamers, to explain how these conflicting narratives can co-exist and how women navigate their contradictions. The dissertation posits that industrial changes and the broadening of gaming audiences have motivated a Gramscian crisis of authority, where previously hegemonic male gamers fear losing their privileged position in this space. As a protective measure, they have reacted with both overtly and implicitly sexist forces, such as gender-based harassment, that marginalize non-male gamers, barring them from cultural power. This works to maintain what this project describes as a “core” of gaming culture that is exclusionary and misogynistic. At the same time, women and other marginalized audiences express deep pleasure in gaming and have developed nuanced strategies for managing their exclusion, pursuing positive gaming experiences, and competing with men on their own turf. In doing so, they put themselves in a complicated position, often simultaneously enjoying their identity as gamers while being told they should not possess that identity. By embodying their conflicting identities in diverse and negotiated ways, however, they work to break down the idea of “women” as an essentialized group and instead outline new ways of being female. This performs feminist action not only by diversifying ideas of who women can be, but also in demonstrating how they are already deeply connected to technologies like games despite their historic masculinization. Women are barred from gaming identity in many ways, but they are also still already part of its “core”. In addition, their management of conflicted identities illustrates pathways along which players could build networks of affinity across gendered lines, encouraging the development of a more equitable power structure in gaming, and perhaps in other masculinized and sexist spaces as well.PhDCommunication StudiesUniversity of Michigan, Horace H.

    Collective Excitations, NMR, and Phase Transitions in Skyrme Crystals

    Full text link
    At Landau level filling factors near nu =1, quantum Hall ferromagnets form a Skyrme crystal state with quasi-long-range translational and non-collinear magnetic order. We develop an effective low energy theory which explains the presence in these systems of magnetic excitations at low energies below the Larmor gap (Delta) and which predicts a dramatic enhancement of the nuclear spin relaxation rate by a factor of 1000. The effective theory predicts a rich set of quantum and classical phase transitions. Based in part on accurate time-dependent Hartree-Fock calculations of the ordered state collective excitation spectrum, we discuss aspects of the T-nu-Delta crystal phase diagram.Comment: 4 pages REVTEX file and 3 postscript figure

    EuroSpine Task Force on Research: support for spine researchers

    Get PDF
    In recognition of the value of research to the practice of spine care, Federico Balagué and Ferran Pellisé, at the time President and Secretary for EuroSpine, asked Margareta Nordin to set up a Task Force on Research (TFR) for EuroSpine during summer 2011. The concept was to stimulate and facilitate a research community within the society, through two main functions: (1) distribution of EuroSpine funds to researchers; (2) develop and deliver research training/education courses. What has the EuroSpine TFR accomplished since its inception
