Thesen:
1. Jedes Genu valgum, selbst die hochgradigste Form, ist heilbar.
2. Die Brücke'sche Selbststeuerungstheorie des Herzens ist nicht haltbar, vielmehr erfolgt die Füllung der vasa coronaria cordis sowohl in der Systole als auch in der Diastole.
3. Bei allen psychischen Alterationen ist die Syphilis als ätiologisches Moment zu berücksichtigen.
4. Die Anwendung des Cranioc1asten ist der des Cephalotriptor vorzuziehen.
5. Zur Einleitung der künstlichen Frühgeburt empfiehlt sich am meisten die Krause'sche Methode.
Carbene transfer from aliphatic diazoalkanes upon coordinatively unsaturated metal centers is a general synthetic concept that provides straight-forward routes into organo-metallic hydrocarbon chemistry. A comparison focussing on several key reactions of general applicability demonstrates that mononuclear organometal substrates add carbenes that may act as bridging ligands (e.g., compound 6) if they arise from ω,ω'-bisdiazoalkanes. By way of contrast, metal-metal double bonds cleanly form dimetallacyclo-propane-type derivatives under very mild conditions (7-9). The broadest variety of structures is finally encountered with metal-metal triply bonded precursors such as the molybdenum compounds 3: here, the initial diazoalkane adducts are subject to further rearrangement processes commonly leading to metal-metal single bonds (11) or causing irreversible cleavage of the dinuclear metal systems (10).
The German postgraduate degree program in ecotoxicology (SETAC GLB and GDCh) : a success story
(2016)
This article gives a comprehensive overview on the strategy, the development and the progress of the German postgraduate degree program in ecotoxicology (SETAC GLB and GDCh). The program soon prompted positive results: more than 10 years now the courses had an average enrolment rate of 90 %, and employment-seeking graduates from the first courses mostly succeeded in quickly finding employment relevant to their training. With over 450 students enrolled to date, the degree program contributes significantly to the field of Environmental Chemistry and Ecotoxicology.
