White poplar (Populus alba) is a widespread species of the northern hemisphere. Introgressed populations or hybrid zones with the related species of the European aspen (Populus tremula) have been suggested as potential venues for the identification of functionally important variation for germplasm conservation, restoration efforts and tree breeding. Data on the genetic diversity and structure of...

Viele diagnostische Verfahren in der Klinischen Psychologie und Psychiatrie stützen sich auf retrospektive Selbstberichte. Solche retrospektiven Selbstberichte sind häufig beeinträchtig durch Erinnerungsfehler und eignen sich kaum, um kurzfristige Veränderungen des Verhaltens über die Zeit oder verschiedene Situationen hinweg abzubilden. Ambulantes Assessment bezeichnet diagnostische...

Two related flower-expressed gene copies belonging to the SF21 (sunflower-21) gene family have been isolated from Senecio squalidus (Oxford Ragwort, Asteraceae). These gene copies are differentially expressed in pollen and pistil tissues; ORSF21B (Oxford Ragwort SF21B) is expressed exclusively in mature pollen, whereas ORSF21A (Oxford Ragwort...

The enemy release hypothesis posits that the initial success of invasive species depends on the scarcity and poor adaptation of native natural enemies such as predators and parasitoids. As for parasitoids, invading hosts are first attacked at low rates by a species-poor complex of mainly generalist species. Over the years, however, parasitoid richness may increase either because the invading host...

The primary products, i.e., the radical cations and radicals obtained on oxidation of the glucobrassicin metabolites (and dietary supplements), indole-3-carbinol (I3C) and diindolylmethane (DIM), and those from parent indole (I) are characterized in an ionic liquid and in Ar matrices. The radical cations of I and I3C are stable toward (photo)deprotonation under these conditions, but the resulting...

The magnetic induction in superlattices comprising thin layers of the high-Tc superconductor YBa2Cu3O7 (YBCO) and the ferromagnet La2/3Ca1/3MnO3 (LCMO) has been investigated by polarised neutron reflectometry measurements. The data provide evidence for a surprisingly strong mutual interaction of the superconducting and the ferromagnetic order parameters. In the region of the interfaces a...

Contexte théorique En Suisse, comme dans la plupart des pays industrialisés, on estime que 20% des adolescents souffre de problèmes psychiques et un grand nombre d’entre eux ne bénéficient pas de traitement. De plus, la plupart des recherches longitudinales sont en accord pour affirmer que les problèmes psychiques graves qui surgissent pendant l’enfance ou l’adolescence et qui ne sont...

The thermal conductivity of concentrated colloids in fluid, glass, and gel states was analyzed. SiO₂ colloids at 10−31 vol % and Al₂O₃ colloids at 4.8 vol % in the fluid, the gel, and the glassy states were studied by dynamic light scattering, rheology, and transmission electron microscopy. Thermal conductivity of the three states was measured as a function of volume fraction. For the...

Self-diffusion NMR is used to investigate monodispersed oil in water emulsions and the subsequent gel formed by removing the water through evaporation. The radius of the oil droplets in the emulsions is measured using a number of diffusion methods based on the measurement of the mean squared displacement of the oil, water, and tracer molecules. The results are consistent with the known size of...
