Measurement of pseudorapidity distributions of charged particles in proton-proton collisions at root s=8 TeV by the CMS and TOTEM experiments Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2014-10-01) Pseudorapidity (eta) distributions of charged particles produced in proton-proton collisions at a centre-of-mass energy of 8 TeV are measured in the ranges vertical bar eta vertical bar < 2.2 and 5.3 < vertical bar eta vertical bar < 6.4 covered by the CMS and TOTEM detectors, respectively. The data correspond to an integrated luminosity of L = 45 mu b(-1). Measurements are presented for three event categories. The most inclusive category is sensitive to 91-96 % of the total inelastic proton-proton cross se...
Seasonal variability of the Caspian Sea three-dimensional circulation, sea level and air-sea interaction Ibrayev, R. A; Ozsoy, E; Schrum, C.; Sur, H. I. (Copernicus GmbH, 2010-3-3) <jats:p>Abstract. A three-dimensional primitive equation model including sea ice thermodynamics and air-sea interaction is used to study seasonal circulation and water mass variability in the Caspian Sea under the influence of realistic mass, momentum and heat fluxes. River discharges, precipitation, radiation and wind stress are seasonally specified in the model, based on available data sets. The evaporation rate, sensible and latent heat fluxes at the sea surface are computed interactively through an atmo...
Reliability and validity of the modified conconi test on concept II rowing ergometers Celik, O; Kosar, SN; Korkusuz, Feza; Bozkurt, M (Ovid Technologies (Wolters Kluwer Health), 2005-11-01) Celik, O., S.N. Kosar, F. Korkusuz, and M. Bozkurt. Reliability and validity of the modified Conconi test on Concept II rowing ergometers. J. Strength Cond. Res. 19(4):871-877. 2005.-The purpose of this study was to assess the reliability and validity of the modified Conconi test on Concept II rowing ergometers. Twenty-eight oarsmen conducted 3 performance tests on separate days. Reliability was assessed using the break point in heart rate (HR) linearity called the Conconi test (CT) and Conconi retest (CRT)...
Providing Cheap Land for Social Housing: Breaching the State Aid Regulations of the Single European Market? Tasan-Kok, Tuna; Groetelaers, Danielle A.; Haffner, Marietta E. A.; van der Heijden, Harry M. H.; Altes, Willem K. Korthals (Informa UK Limited, 2013-04-01) Tasan-Kok T., Groetelaers D. A., Haffner M. E. A., van der Heijden H. M. H. and Korthals Altes W. K. Providing cheap land for social housing: breaching the state aid regulations of the single European Market?, Regional Studies. European Union member states are not permitted to provide aid that will distort competition by favouring certain undertakings or the production of certain goods which may then undermine trading in the European market. This prohibition also affects government authorities that are will...
Modeling dissolved oxygen dynamics and hypoxia Peña, M. A.; Katsev, S.; Oguz, T.; Gilbert, D. (Copernicus GmbH, 2010-3-9) <jats:p>Abstract. Hypoxia conditions are increasing throughout the world, influencing biogeochemical cycles of elements and marine life. Hypoxia results from complex interactions between physical and biogeochemical processes, which can not be understood by observations alone. Models are invaluable tools at studying system dynamics, generalizing discrete observations and predicting future states. They are also useful as management tools for evaluating site-specific responses to management scenarios. Here we ...
