    The U.N. Convention on the Recognition and Enforcement of Foreign Arbitral Awards and Issue Preclusion: A Traditional Collateral Estoppel Determination

    Although the United Nations Convention on the Recognition and Enforcement of Foreign Arbitral Awards provides for the “recognition” and “enforcement” of non-domestic arbitral awards in commercial disputes,1 this article will show that in order for an issue resolved through arbitration to be granted preclusive effect in subsequent litigation in the United States, the proponent must also satisfy the traditional requirements of collateral estoppel. In this way, the Convention’s reach is not quite as expansive as a party might expect, for the ensuing judicial analysis often involves complex questions of law and fact while maintaining respect for the favored status of international commercial arbitration. The result is far from per se preclusivity

    Abrupt Longitudinal Magnetic Field Changes and Ultraviolet Emissions Accompanying Solar Flares

    Get PDF
    We have used Transition Region and Coronal Explorer (TRACE) 1600 \AA images and Global Oscillation Network Group (GONG) magnetograms to compare ultraviolet (UV) emissions from the chromosphere to longitudinal magnetic field changes in the photosphere during four X-class solar flares. An abrupt, significant, and persistent change in the magnetic field occurred across more than ten pixels in the GONG magnetograms for each flare. These magnetic changes lagged the GOES flare start times in all cases, showing that they were consequences and not causes of the flares. Ultraviolet emissions were spatially coincident with the field changes. The UV emissions tended to lag the GOES start times for the flares, and led the changes in the magnetic field in all pixels except one. The UV emissions led the photospheric field changes by 4 minutes on average with the longest lead being 9 minutes, however, the UV emissions continued for tens of minutes, and more than an hour in some cases, after the field changes were complete. The observations are consistent with the picture in which an Alfv\'{e}n wave from the field reconnection site in the corona propagates field changes outward in all directions near the onset of the impulsive phase, including downwards through the chromosphere and into the photosphere, causing the photospheric field changes, whereas the chromosphere emits in the UV in the form of flare kernels, ribbons and sequential chromospheric brightenings during all phases of the flare

    Psychological Pathology and Aging in Cervantes’s Don Quixote de La Mancha

    Get PDF
    Miguel de Cervantes wrote his most famous work, Don Quixote de La Mancha, in a prison cell after a life of great misfortune. The work he created, however, changed his fate, and to this day lives on as one of the most-read pieces of all time. Unique to Cervantes’s literary creation is the applicability of its themes across history. Though the setting is 16th-Century Spain, the topics of the work include aspects of psychopathology, personality, and aging. This synthesis of psychology, philosophy, and human character outlines concepts that would benefit clinicians in their understanding of geriatric patients, which is among one of many underserved populations in the medical field. This thesis advocates for the merge of literature with clinical study in order to gain insight into the factors that influence an aging person’s psychological state and quality of life before death. A deep analysis of psychological disorders and dysfunctional behaviors will be presented for protagonist Alonso Quijano (Don Quixote)

    Messung der e+e- -Paarproduktion in 2AGeV-C-C-Kollisionen mit HADES

    The search for a modification of hadron properties inside nuclear matter at normal and/or high temperature and density is one of the more interesting issues of modern nuclear physics. Dilepton experiments, by providing interesting results, give insight into the properties of strong interaction and the nature of hadron mass generation. One of these research tools is the HADES spectrometer. HADES is a high acceptance dilepton spectrometer installed at the heavy-ion synchrotron (SIS) at GSI, Darmstadt. The main physics motivation of HADES is the measurement of e+e- pairs in the invariant-mass range up to 1 GeV/c2 in pion- and proton-induced reactions, as well as in heavy-ion collisions. The goal is to investigate the properties of the vector mesons rho, omega and of other hadrons reconstructed from e+e- decay pairs. Dileptons are penetrating probes allowing to study the in-medium properties of hadrons. However, the measurement of such dilepton pairs is difficult because of a very large background from other processes in which leptons are created. This thesis presents the analysis of the data provided by the first physic run done with the HADES spectrometer. For the first time e+e- pairs produced in C+C collisions at an incident energy of 2 GeV per nucleon have been collected with sufficient statistics. This experiment is of particular importance since it allows to address the puzzling pair excess measured by the former DLS experiment at 1.04 AGeV. The thesis consists of five chapters. The first chapter presents the physics case which is addressed in the work. In the second chapter the HADES spectrometer is introduced with the characteristic of specific detectors which are part of the spectrometer. Chapter three focusses on the issue of charged-particle identification. The fourth chapter discusses the reconstruction of the di-electron spectra in C+C collisions. In this part of the thesis a comparison with theoretical models is included as well. The conclusion and final remarks are given in chapter five.Eines der Hauptziele der modernen Kernphysik ist die Untersuchung der Modifikation von Eigenschaften von Hadronen bei normaler und hoher Temperatur und Dichte. Dileptonen-Experimente liefern interessante Ergebnisse und geben einen Einblick in die Eigenschaften der starken Wechselwirkung und in die Natur der Massenerzeugung von Hadronen. Eines dieser Forschungswerkzeuge ist das HADES Spektrometer. HADES ist ein Dileptonen Spektrometer mit hoher Akzeptanz am Schwerionensynchroton der GSI in Darmstadt. Die wesentliche physikalische Motivation des Experiments ist, e+e- -Paare im invarianten Massenbereich bis GeV/c2, sowohl in pion- und protoninduzierten Reaktionen, als auch in Schwerionenkollisionen zu messen. Das Ziel ist die Untersuchung der Eigenschaften der Vektormesonen rho, omega und anderer Hadronen, welche aus e+e- -Paare rekonstruiert werden. Da Dileptonen nicht durch die starke Wechselwirkung beeinflusst werden, machen sie das Studium der Eigenschaften von Hadronen in Kernmaterie möglich. Allerdings ist die Messung dieser Dileptonenpaare schwierig, da Leptonen, die in anderen Prozessen erzeugt werden, einen grossen Untergrund erzeugen. In dieser Arbeit werden die Analyse von Daten, die mit dem HADES Spektrometer aufgenommen wurden, so wie Resultate derselben, diskutiert. Zum ersten Mal wurden mit ausreichender Statistik e+e- -Paare aufgezeichnet, die in der Kollision C+C bei einer Projektilenergie von 2 GeV per Nukleon erzeugt wurden. Dieses erste Experiment der HADES Kollaboration, da es ermöglicht, den von der DLS Kollaboration bei 1.04 AGeV gemessenen Paar-Überschuss zu verifizieren. Diese Arbeit besteht aus fĂŒnf Kapiteln. Das erste Kapitel beschreibt die dieser Arbeit zugrunde liegende Physik. Im zweiten Kapitel wird das HADES Spektrometer mit den typischen Eigenschaften der einzelnen Komponenten vorgestellt. Kapitel 3 fokussiert das Thema der Identifikation von geladenen Teilchen. Das 4. Kapitel prĂ€sentiert die Rekonstruktion von Dielektronen-Spektren in C+C Kollisionen. In diesem Teil der Arbeit wird auch der Vergleich mit theoretischen Modellen berĂŒcksichtigt. Die Schlussfolgerungen befinden sich im Kapitel 5
