    Utility operational experience on the NASA/DOE MOD-0A 200-kW wind turbine

    Get PDF
    The Mod-0A 200 wind turbine was designed and fabricated as part of the Federal Wind Energy Program. Early wind turbine operation and performance data were obtained while gaining initial experience in the operation of large, horizontal axis wind turbines in typical utility environments. The Mod-0A wind turbine was turned over to the Town of Clayton Light and Water Plant, Clayton, NM, for utility operation and on December 31, 1978, the machine had completed ten months of utility operation. The machine is described and the recent operational experience at Clayton, NMis documented

    Imaging in-stent restenosis: an inexpensive, reliable, and rapid preclinical model.

    Preclinical models of restenosis are essential to unravel the pathophysiological processes that lead to in-stent restenosis and to optimize existing and future drug-eluting stents. A variety of antibodies and transgenic and knockout strains are available in rats. Consequently, a model for in-stent restenosis in the rat would be convenient for pathobiological and pathophysiological studies. In this video, we present the full procedure and pit-falls of a rat stent model suitable for high throughput stent research. We will show the surgical procedure of stent deployment, and the assessment of in-stent restenosis using the most elegant technique of OCT (Optical Coherence Tomography). This technique provides high accuracy in assessing plaque CSAs (cross section areas) and correlates well with histological sections, which require special and time consuming embedding and sectioning techniques. OCT imaging further allows longitudinal monitoring of the development of in-stent restenosis within the same animal compared to one-time snapshots using histology

    A Commentary on Althusser's 1963 Presentation of Bourdieu and Passeron

    The commentary provides contextual information about the seminar which Bourdieu and Passeron gave in the École Normale Supérieure on 6 December 1963. It appears that the intended series of seminars was curtailed, perhaps because the initial seminar of 6 December exposed the extent to which Althusser was formally managing the intentions of his guest speakers and resisting the implications of their ongoing research on students and their studies. The commentary argues that the conflict between Althusser and Bourdieu/Passeron was inter-generational in that Althusser’s attitudes had been shaped by his experience as a victim of Nazi oppression whereas those of Bourdieu/Passeron were defined, instead, by their unwilling participation in the French colonial oppression of indigenous Algerians. Althusser was intent on examining philosophically the validity of various contemporary versions of social science whereas Bourdieu and Passeron were engaged in educational research which was scrutinizing sociologically the validity of precisely this supposedly detached philosophical perspective. In short, the commentary is aligned with the Bourdieu/Passeron position in that it seeks to offer an historical sociology of the encounter of December 1963
