Excited states of the N = Z = 33 nucleus As-66 have been populated in a fusion-evaporation reaction and studied using gamma-ray spectroscopic techniques. Special emphasis was put into the search for candidates for the T = 1 states. A new 3(+) isomer has been observed with a lifetime of 1.1(3) ns. This is believed to be the predicted oblate shape isomer. The excited levels are discussed in terms of the shell model and of the complex excited Vampir approaches. Coulomb energy differences are determined from the comparison of the T = 1 states with their analog partners. The unusual behavior of the Coulomb energy differences in the A = 70 mass region is explained through different shape components (oblate and prolate) within the members of the same isospin multiplets. This breaking of the isospin symmetry is attributed to the correlations induced by the Coulomb interaction.

Um den Zusammenhang zwischen Hexerei und Ethnizität zu verdeutlichen, werden in diesem Artikel verschiedene theoretischer Ansätze zu Hexerei am Beispiel der Jãana und ihrer Nachbarn im Südwesten von Burkina Faso diskutiert. Dadurch werden sowohl die Parallelen – insbesondere zur Arbeit von Peter Geschiere – als auch die Besonderheiten zu anderen Studien deutlich. Der von mir verfolgte multiethnische Ansatz zeigt, dass Hexerei nicht nur innerhalb einer ethnischen Gruppe für das Zusammenleben relevant ist, sondern auch über ethnische Grenzen hinweg. Die Berücksichtigung der Selbst- und Fremdwahrnehmungen sowie der Interaktion zwischen Angehörigen verschiedener Ethnien (Jãana, Phuo und Lobi) schuf die Voraussetzung, ein differenziertes Bild von Hexerei und Ethnizität im bäuerlichen Alltag zu erhalten. Eine wichtige Erkenntnis ist dabei, dass manche Akteure ihr Hexer-Image bzw. die ihnen zugeschriebene okkulten Kräfte nicht nur als Mittel im Machtkampf mit anderen benutzen, sondern auch als Teil ihrer ethnischen Identität und Andersartigkeit ansehen.

We examined 66 cats with salinomycin intoxication. Salinomycin caused different LMN signs of varying degrees of severity in all cases. Changes in blood work were unspecific, with the most frequent being increased serum creatine kinase activity, leukocytosis, and increased liver enzymes. Pathological electrodiagnostic findings: fibrillation potentials and positive sharp waves were detected in 10 cases, motor nerve conductance velocity was mildly decreased in 8/12 cats, and sensory nerve conductance velocity and repetitive nerve stimulation were normal in all examined cases. In five cases the peripheral neuropathy was confirmed by pathohistology. Fluid therapy and supportive care were used as therapy and 52 cats recovered completely. The probability for complete remission was significantly different between mildly and severely affected cases. It seems that the severity of clinical signs and prognosis correlate well with the amount of toxin ingested. We conclude that early recognition and decontamination combined with supportive care results in complete recovery.

The study of a 66 year old woman's medical chart revealed many discordant elements, leading to the diagnosis of Munchausen's syndrome. The patient had been treated over a period of 20 years at the Medical polyclinic for a variety of symptoms concerning virtually all organs. Her son's chart similarly contains discordant elements, rising the suspicion of a Munchausen Syndrome "by proxy". With this case report, historical aspects and the therapeutic challenge of this syndrome are outlined.

Foot-and-mouth disease (FMD) is a highly contagious disease that caused several large outbreaks in Europe in the last century. The last important outbreak in Switzerland took place in 1965/66 and affected more than 900 premises and more than 50,000 animals were slaughtered. Large-scale emergency vaccination of the cattle and pig population has been applied to control the epidemic. In recent years, many studies have used infectious disease models to assess the impact of different disease control measures, including models developed for diseases exotic for the specific region of interest. Often, the absence of real outbreak data makes a validation of such models impossible. This study aimed to evaluate whether a spatial, stochastic simulation model (the Davis Animal Disease Simulation model) can predict the course of a Swiss FMD epidemic based on the available historic input data on population structure, contact rates, epidemiology of the virus, and quality of the vaccine. In addition, the potential outcome of the 1965/66 FMD epidemic without application of vaccination was investigated. Comparing the model outcomes to reality, only the largest 10% of the simulated outbreaks approximated the number of animals being culled. However, the simulation model highly overestimated the number of culled premises. While the outbreak duration could not be well reproduced by the model compared to the 1965/66 epidemic, it was able to accurately estimate the size of the area infected. Without application of vaccination, the model predicted a much higher mean number of culled animals than with vaccination, demonstrating that vaccination was likely crucial in disease control for the Swiss FMD outbreak in 1965/66. The study demonstrated the feasibility to analyze historical outbreak data with modern analytical tools. However, it also confirmed that predicted epidemics from a most carefully parameterized model cannot integrate all eventualities of a real epidemic. Therefore, decision makers need to be aware that infectious disease models are useful tools to support the decision-making process but their results are not equal valuable as real observations and should always be interpreted with caution.
