    The Commonwealth Court of Pennsylvania has held that a state-wide high school athletic association by-law which prohibited females from competing and practicing against males violated on its face the equal rights amendment to the Constitution of Pennsylvania. Commonwealth v. Pennsylvania Interscholastic Athletic Association, 18 Pa. Commw. 45, 334 A.2d 839 (1975)

    Design and test of a magnetic thrust bearing

    Get PDF
    A magnetic thrust bearing can be employed to take thrust loads in rotating machinery. The design and construction of a prototype magnetic thrust bearing for a high load per weight application is described. The theory for the bearing is developed. Fixtures were designed and the bearing was tested for load capacity using a universal testing machine. Various shims were employed to have known gap thicknesses. A comparison of the theory and measured results is presented

    The development of a high temperature air heating unit based on the external combustion for integrated gasification combined cycle

    The use of heat exchangers in which the working fluid before it enters the gas turbine is warmed up due to the combustion of fuel or other external energy source still is of interest due to the method advantages: the cleanliness of the working fluid; the ability of using cheap low-grade fuels, solar or nuclear energy; the possibility of usage of the closed gas turbine cycle with gases as a working medium, that having favorable thermodynamic properties in comparison with air (helium, CO2, etc.). However, the desired gas turbine inlet temperature - up to 1,700°C currently not possible to provide even with the use of ceramic heat exchangers. Therefore, this technology is now being considered for solid-fuel micro gas turbines operating at temperatures 900-1100°C, or for reducing the need for fuel gas of integrated gasification combined cycle (IGCC) by the means of preheating of cyclic air as well as it is considered for solar gas turbines and gas turbines on the basis of high temperature gas cooled reactors. The authors have developed a metal recuperative air heater based on external combustion of coal for 500 MW IGCC power plant, the development of IGCC is determined by the Energy strategy of Russia for the period up to 2030. In the article the thermal characteristics of the heating of pressurized air, the possible options for the configuration of the heater, heat-resistant materials suitable for its production and the results of the feasibility calculations are considered. In conclusion the design that allows to significantly reduce the specific capital and operating costs for the heater compared to the classic one is proposed. © Published under licence by IOP Publishing Ltd.This work was carried out at the Ural Federal University and financially supported by the Russian Science Foundation (project number 14-19-00524).Comsol;GazEcos;Interenergo;Russian Foundation for Basic Researc

    Historical re-enactment: narrativity, affect and the sublime

    The Karelian Evacuation Trail is an annual reenactment event which commemorates the uprooting of the Finno-Karelian population from their homeland in present-day Russia, and their resettlement in residual Finland in the aftermath of World War II. Initiated in 2006 by the Society of Children Displaced by the War, the Trail has since been held annually, each time in a different municipality in Southern Finland. In the Evacuation Trail, plot lines derived from family traditions and national literature act as a Gestalt, within which the empirical phenomena gained via sensorial stimuli are perceived. The embodied experience generates a sublime effect and a grounding sense of community among the participants. Based on my case study, I argue that inter-subjective co-creation through embodied performance provides a more inclusive alternative to the institution of 'branded authorship' prevalent in modernist historiography. It is particularly well suited for representing postmodern collectivities, traumatised by major displacements and destabilised by social change and the far-reaching 'dispersal' and 'disembodiment' of contemporary media

    Overview of the Millimeter-Wave Thermal Launch System (MTLS) Project

    In 2012, DARPA challenged the authors to launch a small thermal rocket into the air using millimeter waves. The resulting 2-year program, the Millimeter-Wave Thermal Launch System (MTLS), has been executed by NASA Ames Research Center and involves partnerships with General Atomics DIII-D Tokamak, the Air Force Research Laboratory, and the Army High Energy Laser Systems Test Facility (HELSTF). We define the MTLS program, describe its challenges, and outline its achievement

    An Investigation of the Longitudinal Proximity Effect in Superconducting and Normal Metal TES

    Get PDF
    As the TES volume and (effective) Tc become very small - for volume > the TES Tc, connected at opposite ends of TES approaches zero, superconductivity is induced parallel to the current flow, or longitudinally, and results in a much higher effective TES Te. Here we present effective Te measurements of Mo/Au TES bounded by Nb leads as a function of L which ranges between 4 and 36 micrometer. We observe that the effective Te is suppressed for current density of order 10(exp -6) A/sq micrometers. We also explore the possibility of using a normal metal TES
