    An analysis was made of the cryogenic axial groove methane and axial groove nitrogen heat pipes. Data cover the establishment of reliable start-up and operational data for the cryogenic pipe and its reference control pipes, and requirements for and the applicability of cryogenic heat pipes to NASA coolers

    ERTS-C (Landsat 3) cryogenic heat pipe experiment definition

    A flight experiment designed to demonstrate current cryogenic heat pipe technology was defined and evaluated. The experiment package developed is specifically configured for flight aboard an ERTS type spacecraft. Two types of heat pipes were included as part of the experiment package: a transporter heat pipe and a thermal diode heat pipe. Each was tested in various operating modes. Performance data obtained from the experiment are applicable to the design of cryogenic systems for detector cooling, including applications where periodic high cooler temperatures are experienced as a result of cyclic energy inputs

    Measuring the Impacts of Improving Research Capacity: The Case of Training in Wheat Disease Resistance

    Get PDF
    It is notoriously difficult to assess the economic value of research aimed at improving research capacity, particularly in enhancing human capital. In this paper, a framework is developed and an analysis is undertaken of the value of training for scientists in wheat rust resistance in India. The value of the training is assessed through marginal analysis of the improvement in the level of disease resistence flowing from the increased capacity. On that basis, the value of programs to build human capacity through training or further education can be estimated. While such estimates need to be highly qualified, they provide a basis for quantifying the value of R&D capacity building.capacity building, training, economic, rust, wheat, Research Methods/ Statistical Methods,

    Towards the measurement of the impacts of improving research capacity: an economic evaluation of training in wheat disease resistance

    It is notoriously difficult to assess the economic value of research aimed at improving research capacity, particularly for the human capital component of research capacity. In this paper, a framework is developed and an analysis is undertaken of the value of training for scientists in wheat rust resistance. The value of improving human capital is assessed through a framework based on marginal analysis of the improvement in productivity outcomes flowing from the increased capacity. On that basis, the value of programs to build human capacity through training or further education can be estimated. Although such estimates are necessarily qualified, they provide a basis for quantifying the value of building research and development capacity.capacity building, economic, rust, training, wheat, Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies,

    Beyond and beneath the hierarchical market economy: global production and working-class conflict in Argentina's automobile industry

    Get PDF
    This paper argues that the hierarchical market economy (HME) category does not provide an adequate starting point for addressing capitalist diversity in Latin America. Building from a critical perspective on the global commodity chain (GCC) and global production network (GPN) approaches, it instead considers the impact of firms’ transnational relations and the often neglected role of working-class struggles. It will argue that capitalist diversity can only be understood at the nexus of these ostensibly global and local phenomena; and by specifying the strategic decisions taken by firms in Argentina’s automobile industry, it will account for the failure of that sector. Finally, it examines the role of working-class struggles in the industry in Córdoba, Argentina, arguing that these were vital in shaping the specific and unstable form of capitalist diversity in Argentina, as well as potential alternatives to it
