Diese Vorlesung wurde seit dem Sommersemester 1985 an der FH-Aachen, Abt. Jülich, mit 2 Wochenstunden unter dem Titel „Einführung ind solare Energietechnik" in ständig erweiterter Form gelesen. [...]

The present report contains a summary of the results of Phase I of the German Norwegian geoscientific co-operation. This joint research program entitled "BASIN ANALYSIS AND RESERVOIR STUDIES" was initiated by H.I. [...]

The positron emitter carbon-11 (T$_{1/2}$ =20.3 min) is an ideal radio nuclide for tracers in positron emission tomography (PET). In this study catalytic methods for the synthesis of [$^{11}$C]alcohols have been investigated. [...]

In dieser Arbeit werden Magnetooptische Effekte im Weichröntgenbereich vorgestellt. Der Weichröntgenbereich umfaßt die Photonenenergien von etwa 50 bis 1000 eV, und damit den für das Studium des Magnetismus wichtigen Bereich der 2p $\rightarrow$ 3d Anregungen in den Übergangsmetallen. [...]

The past year was marked by a sequence of milestones reached in advancing the accelerator performance as well as in the preparation and start up of the physics program. These accomplishments were augmented and supported by the theoretical group of our institute [...]

Particle accelerators require that the orbit of the charged particles in the vacuum chamber is controlled to fulfil narrow limits. This is done by magnetic deflectionsystems and exactly adjusted rf-acceleration. [...]

Das Experiment JETSET untersucht die Reaktion $\overline{p}$p $\rightarrow$ $\phi \phi$ mit einem internen Target am LEAR (CERN), wobei die $\phi$-Mesonen jeweils in ihrem Zerfall in zwei geladene Kaonen nachgewiesen werden. Das Thema dieser Arbeit war die Entwicklung einer Auswertekette zur Rekonstruktion von Ereignissen des Typs $\overline{p}$p $\rightarrow$ $K^{+}K^{-}K^{+}K^{-}$ sowie der Extraktion eines Signals der resonanten Produktion $\overline{p}$p $\rightarrow$ $\phi \phi \rightarrow K^{+}K^{-}K^{+}K^{-}$ [...]

Membranes and strings are non-crossing manifolds, which can, under suitable conditions and if interacting via sufficiently attractive potentials, undergo adhesiontransitions. At low temperatures or strong attraction, the manifolds are tightly bound together; at high temperatures or weak attraction, they are completely separated. [...]

Gram-positive Bakterien wsrden in der lndustrle vieifach zur Hersteliung extrazellularer Enzyme eingesetzt. Über den Mechanismus der Proteintranslokation ist bei diesen Bakterien jedoch im Vergieich zum Gram-negativen Bakteriurn Escherichia coli nur wenig bekannt. [...]

In this work, the evolution of inert gas bubble microstructures in metals by migration and coalescence has been studied by a simulation approach for two typicalexperimental conditions: (A) Coarsening at constant gas content during annealing after low temperature implantation and (B) bubble evolution under continuous gasproduction at elevated temperatures. For the latter case also experiments in which Helium was implanted into Nickel were performed with particular emphasis on thetemperature and production rate dependence of bubble size and density.
