Trajectories of charged particles in the static Ernst space-time

The authors study the trajectories of charged particles in Ernst's space-time representing a static black hole immersed in a magnetic field. They find bound orbits always exist for realistic magnetic field strengths. A similar investigation is carried out for the case of Melvin's magnetic universe and for a corresponding test field superposed on a flat space-time.

The German Military Entrepreneur Ernst von Mansfeld and His Conduct of Asymmetrical Warfare in the Thirty Years War

The dissertation examines aspects of asymmetrical warfare in the war-making of the German military entrepreneur Ernst von Mansfeld during his involvement in the Thirty Years War. Due to the nature of the inquiry, which combines history with military-political theory, the methodological approach of the dissertation is interdisciplinary. The theoretical framework used is that of asymmetrical warfare. The primary sources used in the dissertation are mostly political pamphlets and newsletters. Other sources include letters, documents, and contemporaneous chronicles. The secondary sources are divided into two categories, literature on the history of the Thirty Years War and textbooks covering the theory of asymmetrical warfare. The first category includes biographical works on Ernst von Mansfeld, as well as general histories of the Thirty Years War and seventeenth-century warfare. The second category combines military theory and political science. The structure of the dissertation consists of eight lead chapters, including an introduction and conclusion. The introduction covers the theoretical approach and aims of the dissertation, and provides a brief overlook of the sources and previous research on Ernst von Mansfeld and asymmetrical warfare in the Thirty Years War. The second chapter covers aspects of Mansfeld s asymmetrical warfare from the perspective of operational art. The third chapter investigates the illegal and immoral aspects of Mansfeld s war-making. The fourth chapter compares the differing methods by which Mansfeld and his enemies raised and financed their armies. The fifth chapter investigates Mansfeld s involvement in indirect warfare. The sixth chapter presents Mansfeld as an object and an agent of image and information war. The seventh chapter looks into the counter-reactions, which Mansfeld s asymmetrical warfare provoked from his enemies. The eighth chapter offers a conclusion of the findings. The dissertation argues that asymmetrical warfare presented itself in all the aforementioned areas of Mansfeld s conduct during the Thirty Years War. The operational asymmetry arose from the freedom of movement that Mansfeld enjoyed, while his enemies were constrained by the limits of positional warfare. As a non-state operator Mansfeld was also free to flout the rules of seventeenth-century warfare, which his enemies could not do with equal ease. The raising and financing of military forces was another source of asymmetry, because the nature of early seventeenth-century warfare favoured private military entrepreneurs rather than embryonic fiscal-military states. The dissertation also argues that other powers fought their own asymmetrical and indirect wars against the Habsburgs through Mansfeld s agency. Image and information were asymmetrical weapons, which were both aimed against Mansfeld and utilized by him. Finally, Mansfeld s asymmetrical threat forced the Habsburgs to adapt to his methods, which ultimately lead to the formation of a subcontracted Imperial Army under the management and leadership of Albrecht von Wallenstein. Therefore Mansfeld s asymmetrical warfare ultimately paved way for the kind of state-monopolized, organised, and symmetrical warfare that has prevailed from 1648 onwards. The conclusion is that Mansfeld s conduct in the Thirty Years War matched the criteria for asymmetrical warfare. While traditional historiography treated Mansfeld as an anomaly in the age of European state formation, his asymmetrical warfare has begun to bear resemblance to the contemporary conflicts, where nation states no longer hold the monopoly of violence.

J. B. S. Haldane, Ernst Mayr and the Beanbag Genetics Dispute

Starting from the early decades of the twentieth century, evolutionary biology began to acquire mathematical overtones. This took place via the development of a set of models in which the Darwinian picture of evolution was shown to be consistent with the laws of heredity discovered by Mendel. The models, which came to be elaborated over the years, define a field of study known as population genetics. Population genetics is generally looked upon as an essential component of modern evolutionary theory. This article deals with a famous dispute between J. B. S. Haldane, one of the founders of population genetics, and Ernst Mayr, a major contributor to the way we understand evolution. The philosophical undercurrents of the dispute remain relevant today. Mayr and Haldane agreed that genetics provided a broad explanatory framework for explaining how evolution took place but differed over the relevance of the mathematical models that sought to underpin that framework. The dispute began with a fundamental issue raised by Mayr in 1959: in terms of understanding evolution, did population genetics contribute anything beyond the obvious? Haldane's response came just before his death in 1964. It contained a spirited defense, not just of population genetics, but also of the motivations that lie behind mathematical modelling in biology. While the difference of opinion persisted and was not glossed over, the two continued to maintain cordial personal relations.

A poética do sublime na teoria da tragédia de Friedrich Schiller

Em sua breve carreira filosófica, o poeta e dramaturgo alemão Friedrich Schiller (1759-1805) se apropriou do conceito kantiano do sublime, identificando-o ao trágico e à tragédia, manifestação artística que seria genuinamente regulada por princípios estéticos daquela ordem. Deste modo, buscamos neste trabalho relacionar o caráter subjetivo da experiência do sublime com as suas implicações de ordem prática para a arquitetura da tragédia, em especial as que dizem respeito à estrutura ideal do drama, intimamente vinculada à sua finalidade, que é a efetivação do efeito estético que lhe cabe por definição. Se, por uma via, o pensamento de Schiller caminha em direção ao desenvolvimento de uma concepção do trágico a partir de um dos conceitos fundamentais da estética moderna, por outra ele permanece atrelado à tradição aristotélica quando se concentra no estudo da tragédia enquanto gênero literário e busca por meio deste estudo estabelecer regras para a citação dramatúrgica. Assim, Schiller constrói uma poética do sublime, um programa de arte que inaugura um debate importante sobre o fenômeno do trágico na filosofia alemã. Mas, como pretendemos defender, é justamente a concepção do trágico forjada a partir de uma interpretação acentuadamente moral do sublime que torna o conteúdo de sua teoria da tragédia problemático, embora tal teoria seja a resposta encontrada por Schiller para perguntas ainda pertinentes. Afinal, por que nos entretêm assuntos trágicos?

Escritor-personagem / personagem-escritor: Daniel Galera e o projeto Amores Expressos

Diante da recorrência da criação de personagens-escritores nas obras brasileiras de ficção publicadas a partir dos anos 1990, foi escolhida a produção de Daniel Galera como estudo de caso. O personagem-escritor foi observado como estratégia para discutir questões relativas à cena literária contemporânea. Foi delimitado como corpus dessa pesquisa o blog criado durante a estada de Daniel Galera em Buenos Aires, ao participar do projeto Amores Expressos, e o romance Cordilheira (2008), escrito como fruto dessa experiência. Tendo em vista a trajetória de sua carreira em constante relação com a internet, foi analisada a construção do escritor-personagem no blog hospedado no site do projeto, em contraponto à figura do personagem-escritor no romance. Para tanto, foram utilizados textos sobre a autoficção, a performance e a autoria. Na comparação dos textos de ambos os suportes, foram evidenciadas semelhanças e diferenças nas problematizações a respeito da formação do autor. Foi investigada a inserção de trechos do blog no romance como estratégia que oferece complexidade nos espelhamentos das imagens e enriquece os efeitos de leitura do romance

Camarāo de profundidade: relatório dos cruzeiros realizados com o n/i "Ernst Haeckel" em Agosto-Setembro 1980, Novembro-Dezembro 1980, Janeiro-Fevereiro 1981, Janeiro-Fevereiro 1982

Reports of cruises carried out off Mozambique between parallels 21 degree 00 and 26 degree 20'S and at depths of 400 and 800 meters including abundance indices, catch composition, geographic and bathymetric distributions of shrimp catches are presented. The main species found were Hymenopenaeus triarthrus and Aristeomorpha foliacea which represent 64 to 72% of total catches.

A report on a survey with the r/v "Ernst Haeckel" in July-August 1980: shallow-water shrimp and by-catch, oceanography

A survey of the Sofala Bank (Mozambique) was conducted to: estimate the abundance of shallow-water shrimp in the area between 16 degree 20'S and 20 degree 20'S, from 5 to 100 meters; estimate the shallow-water shrimp species composition and distribution pattern of main species. Collect biological data of the main species, Penaeus indicus and Metapenaeus monoceros; study the shrimp by-catch, species composition and biological data collection of the most abundant species of commercial value; and collect environmental data to clarify the shelf circulation on the Sofala Bank and the main oceanic features in the regions 15 degree S to 18 degree S and south of 22 degree S.
