This event was interpreted as gravitational microlensing by Garnavich, Loeb \& Stanek and subsequently used to derive constraints on the structure of the GRB optical afterglow. In this paper, we use these structural parameters to calculate the probability of such a microlensing event in a realistic scenario, where all compact objects in the universe are associated with observable galaxies. For GRB000301C at a redshift of z=2.04, the a posteriori probability for a microlensing event with an amplitude of m>=0.95mag (as observed) is 0.7 per cent (2.7 per cent) for the most plausible scenario of a flat -dominated Friedmann- Robertson-Walker (FRW) universe with m=0.3 and a fraction f*=0.2 (1.0) of dark matter in the form of compact objects. If we lower the magnification threshold to m>=0.10mag, the probabilities for microlensing events of GRB afterglows increase to 17 per cent (57 per cent). We emphasize that this low probability for a microlensing signature of almost 1mag does not exclude that the observed event in the afterglow light curve of GRB000301C was caused by microlensing, especially in light of the fact that a galaxy was found within 2arcsec from the GRB. In that case, however, a more robust upper limit on the a posteriori probability of ~5 per cent is found. It does show, however, that it will not be easy to create a large sample of strong GRB afterglow microlensing events for statistical studies of their physical conditions on microarcsec scales.}, language = {en} } @article{WellsteinLangerBraun2001, author = {Wellstein, Stephan and Langer, Norbert and Braun, H.}, title = {Formation of contact in massive close binaries}, year = {2001}, language = {en} } @article{Peitsch2001, author = {Peitsch, Helmut}, title = {Zur Rezeption linker und marxistischer Literatur : anl{\"a}ßlich von Sven Hanuscheks "Heinar Kipphardts Bibliothek"}, year = {2001}, language = {de} } @article{Klein2001, author = {Klein, Eckart}, title = {M{\"o}glichkeiten und Grenzen der Genfer Fl{\"u}chtlingskonvention f{\"u}r die Arbeit im 21.

The study consisted of four test phases having a length of 9 days in each case, where 8 healthy free- living subjects were adjusted to individual energy requirements at maintenance level. Between the tests, wash-out phases of 4-5 months were inserted to avoid adaptation effects. By using a standard breakfast of constant composition, satiety was evaluated by applying the concept of categorical comparison, which was based on the common fact, that the perception between two meals is changed and usually a set of sensations can be discriminated. These were termed very full and full (just after finishing a meal), appetite and hungry (just before the next meal). These sensations were used as categories on a categorical scale. The evaluation of satiety was performed such that on each day of the four test phases the subjects had to select over a period of 4 h every 30 min one category out of the four, what corresponded to the individual sensation at that time. This procedure was followed by a mathematical treatment of data such that the individual judgements were transformed into a numerical system. As a result, the time course of satiety was available characterizing the time-dependent change of the interoception after consuming the test meal. Using this concept highly reliable results were obtained as demonstrated by the comparison of the four test series.}, language = {en} } @article{Brosch2001, author = {Brosch, Renate}, title = {Nackte Akte : Repr{\"a}sendation weiblicher K{\"o}rper und der b{\"o}se Blick des Begehrens}, year = {2001}, language = {de} } @book{OPUS4-18314, title = {Gemeinsam einsam : die Region Berlin-Brandenburg}, series = {Region - Nation - Europa}, volume = {8}, journal = {Region - Nation - Europa}, editor = {Kleger, Heinz}, publisher = {LIT}, address = {Hamburg}, isbn = {3-8258-5493-0}, pages = {270 S. : graph.

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{OPUS4-18312, title = {Physik : Kl. 7/8, Lehrerbd., Sekundarschule Sachsen-Anhalt}, editor = {Mikelskis, Helmut and Wilke, Hans-Joachim}, publisher = {Volk-und-Wissen-Verl.}, address = {Berlin}, isbn = {3-06-022271-1}, pages = {136 S.}, year = {2001}, language = {de} } @article{Rheinberg2001, author = {Rheinberg, Falko}, title = {Motivationstraining}, isbn = {3- 8017-1347-4}, year = {2001}, language = {de} } @article{LundRheinbergGladasch2001, author = {Lund, Brigitte and Rheinberg, Falko and Gladasch, Ulrike}, title = {Ein Elterntraining zum motivationsf{\"o}rderlichen Erziehungsverhalten in Leistungskontexten}, year = {2001}, language = {de} } @article{Rheinberg2001, author = {Rheinberg, Falko}, title = {Paradoxe Effekte von Lob und Tadel}, year = {2001}, language = {de} } @book{Liebers2001, author = {Liebers, Klaus}, title = {Physik : Kl. 7/8, [Hauptbd.], Sekundarschule Sachsen-Anhalt}, editor = {Mikelskis, Helmut and Wilke, Hans-Joachim}, publisher = {Volk-und-Wissen-Verl.}, address = {Berlin}, isbn = {3-06-020734-8}, pages = {192 S.}, year = {2001}, language = {de} }
