How do Astronaut Candidate Profiles differ from Airline Pilot Profile
No full text Sixteen years after the second Europe-wide astronaut selection campaign, the European Space Agency started the third campaign by putting out a call for new astronauts in 2008. Due to extreme environmental conditions, expensive scientific experiments, and high public interest, not only are the psychological requirements on a high level, but they are also wide in variety: Besides cognitive and psychomotor requirements, greater importance than in comparable campaigns was put on personality and behavioral aspects, especially regarding interpersonal aspects. The psychological selection was conducted in two steps: Phase 1 concentrated mainly on performance tests and Phase 2 focused on personality and interpersonal behavior. Out of the 902 tested candidates, 46 fulfilled the psychological requirements. Significant differences were found between the astronaut candidates and the general population as well as airline pilot candidates. </jats:p
A Maschke type theorem for relative Hom-Hopf modules
No full textsummary:Let be a monoidal Hom-Hopf algebra and a right -Hom-comodule algebra. We first introduce the notion of a relative Hom-Hopf module and prove that the functor from the category of relative Hom-Hopf modules to the category of right -Hom-modules has a right adjoint. Furthermore, we prove a Maschke type theorem for the category of relative Hom-Hopf modules. In fact, we give necessary and sufficient conditions for the functor that forgets the -coaction to be separable. This leads to a generalized notion of integrals

Jahrbuch für Fremdenverkehr. 48th ed. 2007: 134-154.Der vorliegende Beitrag beschäftigt sich mit der zunehmenden Bedeutung von Schwellenländern für die deutsche Tourismusindustrie. Auf Basis einer länderübergreifenden Imagestudie werden Unterschiede und Gemeinsamkeiten verschiedener europäischer Sommerurlaubsländer in der Wahrnehmung potenzieller Besucher herausgearbeitet. Diese werden dann am Beispiel von Bulgarien in eine touristische Positionierungsstrategie für Schwellenländer überführt
Impaired trigeminal nociceptive processing in patients with trigeminal neuralgia
No full textBackground: Trigeminal neuralgia (TN) usually leads to paroxysms of short lasting but very severe pain. Between the attacks the patient is usually asymptomatic, but a constant dull background pain may persist in some cases. The mechanisms associated with the development of this chronic pain are not well understood. Objective: To determine trigeminal nociceptive fiber impairment in patients with TN comparing symptomatic and nonsymptomatic sides using the nociceptive blink reflex (nBR) and pain-related evoked potentials (PREP) and to identify possible central mechanisms of pain chronicity. Methods: We investigated 24 patients with TN without and 18 patients with TN with concomitant chronic facial pain. PREP and nBR were investigated following nociception specific electrical stimulation on both sides of the face and in each division of the trigeminal nerve (V1, V2, and V3). Results: We found prolonged PREP and nBR latencies and reduced amplitudes comparing symptomatic and nonsymptomatic sides in all patients with TN. In patients with chronic facial pain, however, PREP amplitudes were larger and latencies shorter compared to patients with TN without facial pain, while nBR results were similar across groups. Conclusion: The data suggest an impairment of the trigeminal nociceptive system due to demyelination and/or axonal dysfunction on the symptomatic side and locate this defect close to the root entry zone in the brainstem. Moreover, central facilitation of trigeminal nociceptive processing was observed in patients with trigeminal neuralgia with concomitant chronic facial pain indicating overactivation of central sensory transmission. This may represent a possible adaptive mechanism for the development of chronic pai

Conservation laws and open systems on higher-dimensional networks
No full textWe discuss a framework for defining physical open systems on higher-dimensional complexes. We start with the formalization of the dynamics of open electrical circuits and the Kirchhoff behavior of the underlying open graph or 1-complex. It is discussed how the graph can be closed to an ordinary graph, and how this defines a Dirac structure on the extended graph. Then it is shown how this formalism can be extended to arbitrary k-complexes, which is illustrated by a discrete formulation of heat transfer on a two-dimensional spatial domain.
