Abstract

A rockfall dataset for Germany is analysed with the objective of identifying the meteorological and hydrological (pre-) conditions that change the probability for such events in Central Europe. The factors investigated in the analysis are precipitation amount and intensity, freeze-thawing cycles as well as sub-surface moisture. As there is no suitable observational dataset for all relevant sub-surface moisture types (e.g. water in rock pores and cleft water) available, simulated soil moisture and parameterised pore water are tested as substitutes. The potential triggering factors were analysed both for the day of the event as well as for the days leading up to the event. It is found that the most important factor influencing rockfall probability in the research area is precipitation amount at the day of the event but the water content of the ground on that day and freeze-thawing cycles in the days prior to the event also influence the hazard probability. Comparing results with simulated soil moisture and parameterised pore water revealed that precipitation minus potential evaporation evaluated for a weekly period performs well as a proxy for the relevant sub-surface moisture types. A logistic regression model was built, which considers individual potential triggering factors as well as their interactions. Using this model the effects of meteorological conditions on rockfall probability in the Central European low mountain ranges can be quantified. The model suggests that precipitation is most efficient, when the moisture content of the ground is high. An increase of daily precipitation from its local 50th percentile to its 90th percentile approximately doubles the probability for a rockfall event under median sub-surface moisture conditions. When the moisture content of the ground is at its 95th percentile the same increase in precipitation leads to a four-fold increase in rockfall probability. The occurrence of a freeze-thaw cycle in the preceding days can further increase the rockfall hazard. The most critical combination can be expected in the winter season after a freeze-thaw transition which is followed by a day with high precipitation amounts and takes place in a region preconditioned by a high level of sub-surface moisture.

Abstract

Introduction In spite of tremendous progress in the medical and surgical treatment of children with congenital heart disease and dilated cardiomyopathy achieved during the past few decades, for some children a heart transplant remains the only option. Clinically relevant benefits of intracoronary injection of autologous stem cells on cardiac function and remodelling have been demonstrated in adult patients with acute myocardial infarction. Experience with autologous stem cell therapy in children with severe congenital or acquired pump failure is limited to a small number of case reports. Method and results Between 2006 and 2010, nine severely ill children were treated with intracoronary infusion of autologous bone marrow-derived mononuclear cells as part of a compassionate therapy in our centre. No procedure-related unexpected adverse events occurred. There was one patient on extracorporeal membrane oxygenation who died of haemorrhage unrelated to the procedure; three patients proceeded to heart transplantation once a donor heart became available. The other five patients showed an improvement with respect to New York Heart Association classification (greater than or equal to 1), brain natriuretic peptide serum levels, and ejection fraction. Conclusion Similar to adults, intracoronary injection of autologous bone marrow cell is technically feasible and safe for children. On the basis of our data, we propose to perform a pilot study for children with congestive heart failure, to formally assess the efficacy of intracoronary autologous bone marrow cell therapy.

Abstract

In der vorliegenden Arbeit geht es um die Relativistische Schrödingertheorie (RST), welche eine neue Methode zur Behandlung relativistischer Mehrteilchensysteme darstellt. Die RST und die ihr zugrunde liegenden Konzepte, d.h. Eichtheorien und Faserbündel, werden kurz vorgestellt sowie der RST-Formalismus auf den 2-Teilchen Fall mit elektromagnetischer Wechselwirkung spezialisiert. Es wird bewiesen, daß die in der RST auftretenden Mischungs- und Austauscheffekte, welche die zwei Teilchen zusätzlich zur Eichwechselwirkung aneinander koppeln, keine physikalischen Auswirkungen haben, sofern sie nicht gemeinsam auftreten. Der Mischungseffekt läßt sich auf eine Gruppenstruktur, die sogenannte Mischungsgruppe, zurückführen. Zur Behandlung des Austauscheffektes werden neue Feldgrößen eingeführt, welche die RST-Dynamik stark vereinfachen und die Konstruktion einer Lagrange-Dichte für das 2-Teilchen-RST-Feldgleichungssystem ermöglichen. Die physikalischen Auswirkungen des gemeinsamen Auftretens von Mischungs- und Austauscheffekten werden durch die Berechnung der Bindungszustände des He-Atoms in erster Ordnung Störungstheorie und den Vergleich sowohl mit den experimentellen Werten als auch mit den Resultaten der konventionellen Quantentheorie verdeutlicht., The present work deals with Relativistic Schrödinger Theory (RST), which constitutes a new method for treating relativistic many-particle systems; the RST theory and the underlying concepts of gauge theories and fibre bundles are explained and the RST formalism is specialized to the case of 2-particle systems with electromagnetic interactions. It is shown that the RST mixture and exchange effects, which couple the two particles in addition to the gauge interactions, do only influence the physical content of the theory if they both occur simultaneously. The mixture effect is related to a group structure, the so-called mixing group. For the treatment of the exchange effect, new field variables are introduced which simplify the RST dynamics considerably, leading to a Lagrangian formulation of the RST field equations for two particles. The physical impact of the occurence of both mixture and exchange effects is exemplified by calculating the bound-state energy levels of the He-Atom in first order perturbation theory and by comparison with both experimental values and the results of conventional quantum theory.
