    The baryon octet magnetic moments to all orders in flavor breaking; an application to the problem of the strangeness in the nucleon

    Using the general QCD parametrization (GP) we display the magnetic moments of the octet baryons including all flavor breaking terms to any order. The hierarchy of the GP parameters allows to estimate a parameter g0g_{0} related to the quark loops contribution of the proton magnetic moment; its order of magnitude is predicted to be inside a comparatively small interval including the value given recently by Leinweber et al. by a lattice QCD calculationComment: (13 pages- version accepted for publication Phys.Rev.D.

    Theory of water and charged liquid bridges

    Full text link
    The phenomena of liquid bridge formation due to an applied electric field is investigated. A new solution for the charged catenary is presented which allows to determine the static and dynamical stability conditions where charged liquid bridges are possible. The creeping height, the bridge radius and length as well as the shape of the bridge is calculated showing an asymmetric profile in agreement with observations. The flow profile is calculated from the Navier Stokes equation leading to a mean velocity which combines charge transport with neutral mass flow and which describes recent experiments on water bridges.Comment: 10 pages 12 figures, misprints corrected, assumptions more transparen

    The characteristics of the TIROS, GOES, DMSP and LANDSAT systems of satellites are described. The data listed for each system are altitude of orbit, inclination/position, orbit type, orbits per day, expected operational lifetime and the sensor systems. The sensor systems are described as to wavelength of each channel, resolution, field of view and other pertinent information. Data information such as availability rate, collection method, primary use/application and how to obtain additional information is also given

    Analysis and testing of two-dimensional vented Coanda ejectors with asymmetric variable area mixing sections

    Get PDF
    The analysis of asymmetric, curved (Coanda) ejector flow has been completed using a finite difference technique and a quasi-orthogonal streamline coordinate system. The boundary layer type jet mixing analysis accounts for the effect of streamline curvature in pressure gradients normal to the streamlines and on eddy viscosities. The analysis assured perfect gases, free of pressure discontinuities and flow separation and treated three compound flows of supersonic and subsonic streams. Flow parameters and ejector performance were measured in a vented Coanda flow geometry for the verification of the computer analysis. A primary converging nozzle with a discharge geometry of 0.003175 m x 0.2032 m was supplied with 0.283 cu m/sec of air at about 241.3 KPa absolute stagnation pressure and 82 C stagnation temperature. One mixing section geometry was used with a 0.127 m constant radius Coanda surface. Eight tests were run at spacing between the Coanda surface and primary nozzle 0.01915 m and 0.318 m and at three angles of Coanda turning: 22.5 deg, 45.0 deg, and 75.0 deg. The wall static pressures, the loci of maximum stagnation pressures, and the stagnation pressure profiles agree well between analytical and experimental results

    Sport Mega-Events and Public Opposition: A Sociological Study of the London 2012 Olympics

    Get PDF
    This article examines the diverse forms of public opposition, protest, criticism, and complaint in the United Kingdom on the staging of the 2012 Olympic and Paralympic Games in London. Our discussion draws heavily on empirical research, primarily fieldwork and interviews in East London with local residents, opposition groups, business people, politicians, and other stakeholders. The article is separated into three main parts. First, we explore the setting and political?economic context for London 2012. The main Olympic setting?the London Borough of Newham?features very high levels of poverty and ethnic diversity. We argue that London 2012 represented a form of ?festival capitalism? that was part of a broader set of ?New Right two-step? policies in poor urban areas, involving initial Keynesian investment, followed by a deeper and far-reaching array of neo-liberal measures. Second, in the main part of the article, we identify and examine, in turn, six forms of public conflict, criticism, and complaint that centered on the Games, specifically national criticisms (e.g., on distribution of Olympic resources), local criticisms (e.g., on lack of jobs and business benefits), issue-specific campaigns (e.g., on the environment), ?glocal? protests against specific nations and sponsors (e.g., campaigns against BP, Dow, and Rio Tinto), neo-tribal transgressions and situationist spectacles (e.g., mass cycle rides near Olympic venues), and anti-Olympic forums and demonstrations (e.g., critical web sites, multi-group marches). Third, we set out briefly the importance of conducting research into critics and opponents of sport mega-events, and discuss different arguments on how the social impact of protest movements might have been intensified at London 2012. The findings in this article may be extended to examine critical public responses to the hosting of other mega-events in different settings
