Kurzfassung. Die Klassifikation als eine Grundlage des operativen Vorgehens nach instabilen Beckenringfrakturen stellt sich als ausgesprochen schwierig dar. Insbesondere ligamentäre Begleitverletzungen können nur ungenügend diagnostiziert und damit berücksichtigt werden. Um die funktionellen Auswirkungen einer solchen ligamentären Begleitverletzung zu konkretisieren, wurde ein biomechanisches F...

This study examined photoperiodic regulation of affective behaviours in collared lemmings (Dicrostonyx groenlandicus). Male and female lemmings were housed in either long (LD 22:2), intermediate (LD 16:8), or short days (LD 8:16) for 9 weeks. Exposure to short days induced moult to a winter pelage and gonadal regression in male, but not female, lemmings. Lemmings housed in long days reduced anx...

2014 The role of interplanar fluctuations associated with « parallel » vortex loops is considered in the two coupled problems of XY magnetism and superconductivity of the second kind, in a quasitwodimensional situation. Using an admittedly simplified criterion, it is argued that, for weak interplanar couplings, the critical 3d temperature is related to the multiplication of such loops ; it shou...

The belief that Homo sapiens is absolutely dimorphic with the respect to sex chromosome composition, gonadal structure, hormone levels, and the structure of the internal genital duct systems and external genitalia, derives from the platonic ideal that for each sex there is a single, universally correct developmental pathway and outcome. We surveyed the medical literature from 1955 to the presen...
