    A review is given of the test program of a 17 meter Vertical Axis Wind Turbine VAWT. Performance test results are discussed including difficulties encountered during the VAWT operation along with ways of solving these problems

    The Lowest Order Hadronic Contribution to the Muon g−2g-2 Value with Systematic Error Correlations

    We have performed a new evaluation of the hadronic contribution to aμ=(g−2)/2a_{\mu}=(g-2)/2 of the muon with explicit correlations of systematic errors among the experimental data on σ(e+e−→hadrons)\sigma( e^+e^- \to hadrons ). Our result for the lowest order hadronic vacuum polarization contribution is aμhad=702.6(7.8)(14.0)×10−10 a_{\mu}^{had} = 702.6(7.8)(14.0) \times 10^{-10} where the the first error is statistical and the second is systematic. The total systematic error contributions from below and above s=1.4\sqrt{s} = 1.4 GeV are (13.1)×10−10(13.1) \times 10^{-10} and (5.1)×10−10(5.1) \times 10^{-10} respectively, and are hence dominated by the low energy region. Therefore, new measurements on σ(e+e−→hadrons)\sigma( e^+e^- \to hadrons ) below 1.4 GeV can significantly reduce the total error on aμhada_{\mu}^{had}. In particular, the effect on the total errors of new hypothetical data with 3 \% statistical and 0.5 - 1.0 \% systematic errors is presented.Comment: LaTeX with REVTeX style and options: multicol,aps,psfig. 18 pages, postscript figures included after text.

    SEARCH FOR SLOWLY MOVING MAGNETIC MONOPOLES WITH THE MACRO DETECTOR

    A search for slowly moving magnetic monopoles in the cosmic radiation was conducted from October 1989 to November 1991 using the large liquid scintillator detector subsystem of the first supermodule of the MACRO detector at the Gran Sasso underground laboratory. The absence of candidates established an upper limit on the monopole flux of 5.6 x 10(-15) cm-2 sr-1 s-1 at 90% confidence level in the velocity range of 10(-4) less than or similar to beta < 4 x 10(-3). This result places a new constraint on the abundance of monopoles trapped in our solar system

    Annotated record of the detailed examination of Mn deposits from DSDP Leg 44 (Holes 389, 390, 390A, 392 and 392A)

    The western part of the North Atlantic Ocean holds clues to some of the most intriguing questions in marine geology. But because the geologic problems are many and varied, the sites of Leg 44 were multipurpose in nature. In particular, some of the targets were : 1) the Blake Nose, a spur of the Blake Plateau, to determine the nature, age, and origin of reef-like structures recognized on seismic profiles and 2) the Blake Outer Ridge, a long low ridge of sediments that forms the eastern boundary of the Blake-Bahama Basin, where we hoped to study the stratigraphy and sample supposed clathrates
