The paper presents data on the chemical composition of Late Pleistocene-Holocene sediments in the Gakkel Ridge according to data on sediment core PS 70/306-3, offers a hypothetical litho-stratigraphic model, and provides data on chemo-stratigraphic horizons distinguished based on the distribution of carbonates, organic carbon, metals (Fe, Mn, Cu, Zn, Co, Ni, V, Pb), As, and P in the core. Chemical transformations of sediments at the redox barrier are discussed, along with relations between the composition of the sediments and the facies sedimentation conditions.

Populus nigra L. is a pioneer tree species of riparian ecosystems that is threatened with extinction because of the loss of its natural habitat. To evaluate the existing genetic diversity of P. nigra within ex-situ collections, we analyzed 675 P. nigra L. accessions from nine European gene banks with three amplified fragment length polymorphism (AFLP) and five microsatellite [or simple sequence repeat (SSR)] primer combinations, and 11 isozyme systems. With isozyme analysis, hybrids could be detected, and only 3% were found in the gene bank collection. AFLP and SSR analyses revealed effectively that 26% of the accessions were duplicated and that the level of clonal duplication varied from 0% in the French gene bank collection up to 78% in the Belgian gene bank collection. SSR analysis was preferred because AFLP was technically more demanding and more prone to scoring errors. To assess the genetic diversity, we grouped material from the gene banks according to topography of the location from which the accessions were originally collected (river system or regions separated by mountains). Genetic diversity was expressed in terms of the following parameters: percentage of polymorphic loci, observed and effective number of alleles, and Nei’s expected heterozygosity or gene diversity (for AFLP). Genetic diversity varied from region to region and depended, to some extent, on the marker system used. The most unique alleles were identified in the Danube region (Austria), the Rhône region (France), Italy, the Rijn region (The Netherlands), and the Ebro region (Spain). In general, the diversity was largest in the material collected from the regions in Southern Europe. Dendrograms and principal component analysis resulted in a clustering according to topography. Material from the same river systems, but from different countries, clustered together. The genetic differentiation among the regions (Fst/Gst) was moderate. [ABSTRACT FROM AUTHOR]

The analyzing power for elastic n-d scattering was measured at E=13 MeV. The result is in good agreement with experimental data at E=12 MeV and E=14.1 MeV. At backward angles the data are well above the predictions of a rigorous Faddeev calculation using the Paris potential. [ABSTRACT FROM AUTHOR]

Die Nachbehandlung der Knochenbrüche richtet sich nach dem Reizbedürfnis und den DurchströmungsverhÄltnissen. Am Beispiele des Speichenbruches wird gezeigt, da\ kritikloses Anwenden von Hei\luft, Massieren, Bewegen und Zander technik nur Verschlimmerung bringt. Die NebenschÄdigungen beim Speichenbruch (Bandschaden, Ganglien, Meniskussperre, traumatisches ödem, arterielle ErnÄhrungsstörung) verlangen Sonderma\nahmen. [ABSTRACT FROM AUTHOR]
