    Nuclear particle detection using a track-recording solid

    Get PDF
    The design of the nuclear particle detector located in Purdue University's Get Away Special package which was flown aboard STS-7 is detailed. The experiment consisted of a stack of particle-detecting polymer sheets. The sheets show positive results of tracks throughout the block. A slide of each sheet was made for further analysis. Recommendations for similar experiments performed in the future are discussed

    Sustainable apple breedings needs sustainable marketing and management

    Apple breeding programmes are currently in the middle of transition in terms of ownership and management. Until now most of them were funded by the public. Breeding took place by traditional methods since decades in a very sustainable way to develop better apple varieties. Today, increasing loss of national boundaries and globalisation, less interest by national bodies and institutions and rising cost levels for high tech breeding methods entire programmes are nowadays urged to look for new sustainable co- or self-financing business models in order to continue their work. The paper explains through financial calculations how risk can be split by all partners and how the supply chain can be developed further into a value chain by using a collective royalty system on trees and fruit, to add value to all market participants and to support the breeding efforts and to become sustainable through profitability. A leading shift of mindset requires the involvement of variety managers and companies who are coaching the whole process of introduction

    Two-particle correlations and balance functions in p-Pb and Pb-Pb collisions at LHC energies with ALICE

    Recent measurements of two-particle correlations in high-multiplicity p-Pb collisions at sNN=5.02\sqrt{s_{NN}} = 5.02 TeV revealed a long-range structure (large separation in Δη\Delta\eta) at the near- (Δφ≃0\Delta\varphi\simeq0) and away-side (Δφ≃π\Delta\varphi\simeq\pi) of the trigger particle. At LHC energies, these ridge-like structures have not only been observed in Pb-Pb collisions, but also in high-multiplicity pp collisions. In the first case, this phenomenon is commonly related to collectivity in hadron production, i.e. hydrodynamic evolution, whereas in the latter, mechanisms like longitudinal color connections and multi-parton interactions might play an important role. To shed light on the particle production mechanisms in p-Pb and Pb-Pb collisions and answer the question about collectivity, we extend the two-particle correlation analysis for hadrons in two directions: identified particles, which should show a characteristic pattern in case of collective motion in a hydrodynamic medium, and charge-dependent correlations studied with the balance function, which are sensitive to charge-dependent effects like local charge conservation.Comment: 6 pages, 4 figures, EPS-HEP2013 proceeding

    The influence of the scene on linguistic expectations: Evidence from cross-model priming in visual worlds

    Get PDF
    - Numerous studies of utterance mediated gaze in visual scenes have demonstrated that sentence processing is not only incremental but also eager: During processing, listeners form expectations about upcoming arguments and make anticipatory eye movements to relevant displayed objects. - In particular, selectional information from verbs has been shown to guide visual attention to appropriate objects; upon hearing “the boy will eat”, listeners start looking at edible objects even before they are mentioned [1, 2]. - While these studies provide valuable insights into semantic processing, it is not clear whether anticipatory eye movements indeed reflect the purely linguistic activation of likely arguments or whether these anticipatory processes are influenced by the circumscribed visual context. - We present a German cross-modal priming experiment in which we examined listeners sensitivity to selectional restrictions between verbs and their object arguments
