    Malnutrition, poverty and the unsustainable exploitation of natural resources pose serious problems in sub-Saharan Africa (SSA). Overfishing and deforestation not only damage ecosystems, but also put livelihoods at risk ...
  • Holzmann, Helge (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    Web archives constitute valuable sources for researchers in various disciplines. However, their sheer size, the typically broad scope and their temporal dimension make them difficult to work with. We have identified three ...
  • Lanwer, Jens Philipp (Hannover : Gottfried Wilhelm Leibniz Universität, Seminar für deutsche Literatur und Sprache, 2019)
    Eine multimodale Perspektive auf soziale Interaktion verändert „zwangsläufig klassische Gegenstände und Fragestellungen der Konversationsanalyse“ (Schmitt 2005:24). Dies betrifft ganz sicher auch die konversationsanalytisch ...
  • Richardson, Logan Latham (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    Exploiting the quantum nature of atoms through the use of matter-wave interferometry has lead to the development of devices sensitive to, among other things, the local gravitational acceleration. Measurements of the ...
  • Leuteritz, Georg; Lippert, René Bastian; Lachmayer, Roland (Erlangen : Deutsche Gesellschaft für angewandte Optik, 2017-08-04)
    This work examines an approach for the optimization of the optical quality of additively manufactured reflectors. Therefore the parameters of a Selective Laser Melting process, which manipulate surface properties ...
  • Hild, S.; Grote, H.; Smith, J.R.; Hewitson, M. (Bristol : Institute of Physics Publishing, 2006)
    During the S4 LSC science run, the gravitational-wave detector GEO600, the first large scale dual recycled interferometer, took 30 days of continuous data. An instrumental duty cycle greater than 96% and a peak sensitivity ...
  • Mateos, I.; Lobo, A.; Ramos-Castro, J.; Sanjun, J.; Nofrarias, M. (Bristol : Institute of Physics Publishing, 2009)
    The current design, and material implementation of the magnetic field sensing in the LISA Technology Package (LTP) on board LISA Pathfinder (LPF), is based on a set of 4 high-precision 3-axis fluxgate magnetometers. In ...
  • Blume, C.; Ost, J.; Mühlenbruch, M.; Peterhänsel, C.; Laxa, M. (San Francisco, CA : Public Library of Science (PLoS), 2019)
    The non-proteinogenic amino acid ornithine links several stress response pathways. From a previous study we know that ornithine accumulates in response to low CO2. To investigate ornithine accumulation in plants, we shifted ...
  • Degallaix, J. (Bristol : Institute of Physics Publishing, 2010)
    Optical simulation softwares are essential tools for designing and commissioning laser interferometers. This article aims to introduce OSCAR, a Matlab based FFT code, to the experimentalist community. OSCAR (Optical ...
  • Willke, B.; Danzmann, K.; Fallnich, C.; Frede, M.; Heurs, M.; King, P.; Kracht, D.; Kwee, P.; Savage, R.; Seifert, F.; Wilhelm, R. (Bristol : Institute of Physics Publishing, 2006)
    Second generation gravitational wave detectors require high power lasers with several 100W of output power and with very low temporal and spatial fluctuations. In this paper we discuss possible setups to achieve high laser ...
  • Nofrarias, M.; García, Marín, A.F.; Heinzel, G.; Hewitson, M.; Lobo, A.; Sanjun, J.; Ramos-Castro, J.; Danzmann, K. (Bristol : Institute of Physics Publishing, 2009)
    The Diagnostic Subsytem in the LISA Technology Package (LTP) on board the LISA Pathfinder mission (LPF) will characterise those external disturbances with a potential impact on the performance of the experiment coming from ...
