Three representative cases are discussed: stationary cellular flow, stationary shear flow, and percolating flow. Production terms of Fisher-Kolmogorov-Petrovskii-Piskunov type and of Arrhenius type are considered under the assumption of no feedback of the concentration on the velocity. Numerical simulations of advection-reaction-diffusion equations have been performed by an algorithm based on discrete-time maps. The results show a generic enhancement of the speed of front propagation by the underlying flow. For small molecular diffusivity, the front speed Vf depends on the typical flow velocity U as a power law with an exponent depending on the topological properties of the flow, and on the ratio of reactive and advective time scales. For open-streamline flows we find always Vf~U, whereas for cellular flows we observe Vf~U1/4 for fast advection and Vf~U3/4 for slow advection.}, language = {en} } @book{Addison2001, author = {Addison, John T.}, title = {Principles of market-oriented labor market policies}, series = {Diskussionsbeitrag / Europ{\"a}isches Institut f{\"u}r internationale Wirtschaftsbeziehungen, Potsdam}, volume = {84}, journal = {Diskussionsbeitrag / Europ{\"a}isches Institut f{\"u}r internationale Wirtschaftsbeziehungen, Potsdam}, publisher = {Univ.}, address = {Potsdam}, issn = {1430-5445}, pages = {24 S.}, year = {2001}, language = {en} } @book{Adler2001, author = {Adler, Benno Benjamin}, title = {Esra : die Geschichte eines orthodox-j{\"u}dischen Jugendbundes zur Zeit der Weimarer Republik}, series = {J{\"u}dische Kultur}, volume = {8}, journal = {J{\"u}dische Kultur}, editor = {Voigts, Manfred}, publisher = {Harrassowitz}, address = {Wiesbaden}, isbn = {3-447-04433-0}, pages = {487 S.}, year = {2001}, abstract = {Darstellung der Geschichte eines jugendbewegten und daher antiautorit{\"a}ren Jugendbundes orthodoxer Jugendlicher 1918 - 1932 durch ein ehemaliges Mitglied, gest{\"u}tzt auf schriftliche Quellen und Interviews mit {\"U}berlebenden.}, language = {de} } @article{AfshaarvahidHeuerMenzeletal.2001, author = {Afshaarvahid, Shahraam and Heuer, Axel and Menzel, Ralf and Munch, Jesper}, title = {Temporal structure of stimulated-Brillouin-scattering reflectivity considering transversal-mode development}, year = {2001}, language = {en} } @article{AhlersZillmerPikovskij2001, author = {Ahlers, Volker and Zillmer, R{\"u}diger and Pikovskij, Arkadij}, title = {Lyapunov exponents in disordered chaotic systems : avoided crossing and level statistics}, year = {2001}, abstract = {The behavior of the Lyapunov exponents (LEs) of a disordered system consisting of mutually coupled chaotic maps with different parameters is studied. The LEs are demonstrated to exhibit avoided crossing and level repulsion, qualitatively similar to the behavior of energy levels in quantum chaos. Recent results for the coupling dependence of the LEs of two coupled chaotic systems are used to explain the phenomenon and to derive an approximate expression for the distribution functions of LE spacings. The depletion of the level spacing distribution is shown to be exponentially strong at small values. The results are interpreted in terms of the random matrix theory.}, language = {en} } @article{AlbrechtKochLodeetal.2001, author = {Albrecht, Tanja and Koch, Anke and Lode, Anja and Greve, Burkhard and Schneider-Mergener, Jens and Steup, Martin}, title = {Plastidic (Pho1-type) phosphorylase isoforms in potato (Solanum tuberosum L.) plants : expression analysis and immunochemical characterization}, year = {2001}, language = {en} } @article{AltenbergerOberhaensliSteinetal.2001, author = {Altenberger, Uwe and Oberh{\"a}nsli, Roland and Stein, Eckehard and Moghni, Mohsen}, title = {Geochemistry, tectonic setting and geodynamic position of late orogenic dikes in the Melibocus Massiv, Bergstraesser Odenwald}, year = {2001}, language = {en} } @article{AltmannFiehnKloska2001, author = {Altmann, Thomas and Fiehn, Oliver and Kloska, Sebastian}, title = {Integrated studies on plant biology using multiparallel techniques}, year = {2001}, language = {en} } @article{AltmannKossmann2001, author = {Altmann, Thomas and Koßmann, Jens}, title = {Photosynthesis and primary metabolism}, issn = {1360-1385}, year = {2001}, language = {en} } @article{AltmannMuessig2001, author = {Altmann, Thomas and M{\"u}ssig, Carsten}, title = {Brassinosteroid signaling in plants}, year = {2001}, language = {en} }
