Abstract The spawning activities of cod were described in the Arkona Sea from 2009 to 2012 and were compared with estimates of the period 1992 – 1999. Cod spawned mainly from beginning of June till the middle of July every year. In the same period spawning was observed in the Bornholm Sea. The spawning activities in July were limited by water temperature above the critical limits. Spawning activities in spring which were observed in the 90 ties were of lower importance between 2009 and 2012. Higher proportions of spent cod were observed in the Arkona Sea in August and autumn between 2009 and 2012 compared to the earlier period, indicating immigration of cod from the Bornholm Sea after spawning. The study showed that higher proportion of cod with developing sex products were observed in the Arkona Sea between 2009 and 2012 compared to the 90 ties. Kurzfassung Die Laichaktivitäten der Dorsche in der Arkonasee werden für den Zeitraum 2009 – 2012 dargestellt und im Vergleich mit dem Zeitraum 1992 – 1999 diskutiert. Die Hauptlaichaktivitäten haben im Untersuchungszeitraum von Anfang Juni bis Mitte Juli stattgefunden und lagen damit in ihrem jahreszeitlichen Verlauf innerhalb der Zeitperiode der Laichaktivitäten in der angrenzenden Bornholmsee. In der Arkonasee wurden jeweils im Juli diese Ereignisse durch ansteigende Wassertemperaturenbegrenzt. Die, noch in den 90-er Jahren beobachteten, Laichaktivitäten im Frühjahr haben aktuell an Bedeutung verloren. Im Spätsommer und Herbst war ein, im Vergleich zu den 90-er Jahren, höherer Anteil an abgelaichten Tieren in der Arkonasee zu beobachten, der als Indiz für eine Zuwanderung von abgelaichten Dorschen aus der Bornholmsee gewertet wird. Insgesamt hat der Anteil an Tieren mit sich entwickelnden Geschlechtsprodukten (aktive Laicher) im Untersuchungszeitraum, im Vergleich zu den 90-er Jahren, zugenommen.

O presente trabalho tem por objetivo analisar a construção da identidade nos discursos literários de José de Alencar e Mário de Andrade em que o recurso à literatura oral aparece como elemento central. O foco da análise são os textos críticos e teóricos desses autores, tomando-se especialmente em consideração questões da teoria de Johann Gottfried Herder sobre a poesia popular enquanto poesia natural, que deveria servir de matéria prima para a literatura erudita

This paper discusses the Klein–Gordon–Zakharov system with different-degree nonlinearities in two and three space dimensions. Firstly, we prove the existence of standing wave with ground state by applying an intricate variational argument. Next, by introducing an auxiliary functional and an equivalent minimization problem, we obtain two invariant manifolds under the solution flow generated by the Cauchy problem to the aforementioned Klein–Gordon–Zakharov system. Furthermore, by constructing a type of constrained variational problem, utilizing the above two invariant manifolds as well as applying potential well argument and concavity method, we derive a sharp threshold for global existence and blowup. Then, combining the above results, we obtain two conclusions of how small the initial data are for the solution to exist globally by using dilation transformation. Finally, we prove a modified instability of standing wave to the system under study.

We extend the recently proposed Kerr/CFT correspondence to examine the dual conformal field theory of four-dimensional Kaluza-Klein black hole in Einstein-Maxwell-Dilaton theory. For the extremal Kaluza-Klein black hole, the central charge and temperature of the dual conformal field are calculated following the approach of Guica, Hartman, Song and Strominger. Meanwhile, we show that the microscopic entropy given by the Cardy formula agrees with Bekenstein-Hawking entropy of extremal Kaluza-Klein black hole. For the non-extremal case, by studying the near-region wave equation of a neutral massless scalar field, we investigate the hidden conformal symmetry of Kaluza-Klein black hole, and find the left and right temperatures of the dual conformal field theory. Furthermore, we find that the entropy of non-extremal Kaluza-Klein black hole is reproduced by Cardy formula. (C) 2010 Elsevier B.V. All rights reserved.
