    Notes: Abstract Molecular characteristics, especially 18S rDNA sequences, may be of great value for the study of bivalve evolution and its numerous morphological convergencies once the reliability of these data can be evaluated. The analysis of 11 published complete molluscan sequences and two new ones,Arca noae andAtrina pectinata, reveals considerable differences in relative substitution rates. The gastropod and eulamellibranch species have the fastest and Atrina species have the slowest rates. Two methods are used to assess the information contents of the dataset in addition to bootstrap analysis, spectral analysis, and the “pattern of resolved nodes” technique. Tree reconstructions by parsimony, neighbor-joining, and maximum-likelihood differ in regard to the position of the eulamellibranch family Mactridae and ofCrassostrea. Although there is a signal for the monophyly of Bivalvia, Mactridae cluster with Gastropoda in most runs, rendering Bivalvia diphyletic. The position ofCrassostrea was extremely variable, probably due to the high substitution rate of this species.Atrina roots deeper thanArca in all trees, although a corresponding signal in spectral analysis is absent. Phylogenetic signals among the three pectinid species are low but sufficient to resolve the branching pattern. The tree inferred from the 18S rDNA and from morphological data has Bivalvia monophyletic with a basal polytomy of Mactridae,Crassostrea, and the remaining Pteriomorphia, whereArca branches off before Atrina and the Pectinidae.Argopecten is sister group to the other two pectinids; 18S sequence data will have great impact on our understanding of bivalve phylogeny, but only when more sequences of similar substitution rates are available.

    Notes: The objective of this paper is to assess the effect of the socio-economic status (SES) on long-term outcomes of a family-based obesity treatment intervention in prepubertal children. A total of 52 overweight and 26 normal weight children were investigated. Nutritional status, intake of fruit, vegetables and low fat foods, in-between meals, sports club membership, frequency of exercise and daily television viewing were measured before intervention (t0 and after a mean period of 1.3 years (t1. The result obtained indicate that a low SES may serve as abarrier against family-based intervention. The data provide evidence for the idea that there is need for social stratification of future measures of health promotion within families.

    Description / Table of Contents: Abstract In the Pleistocene sediments of the Mosel and some of their tributaries the investigation of the heavy minerals showed a high content of opaques. This fact and the small differences in the distribution of the transparent heavy minerals initiated our ore-mineralogical studies of the opaque heavy minerals. The findings resulted in an exact distinction of the sediments of the Mosel from those of their tributaries by typical Limonite oölites (50 grain % of the opaques) originating from the Minette-formation of Luxemburg. By using this technique it is possible to characterize sediments of the Mosel and to elucidate the origin of the widespread Pleistocene sediments of the Wittlicher Senke area. Aside from geomorphological arguments, the investigations of these sediments produced exact evidence that the Mosel took its course through the Wittlicher Senke (= Wittlicher Mosel-Valley) during the Pleistocene period until the interval of the Upper to Lower MT-times (= Obere und Untere Mittelterrasse). Therefore, the Mosel ran through two valleys (bifurcation) between Schweich and Mülheim/Lieser until the Upper MT-time which was postulated byGrebe (1881). In addition this method enabled us to verify the loess being river loess, blown out of the sediments of the Mosel.
    Abstract: Résumé En analysant les minéraux lourds des sédiments du pléistocène de la Moselle et de quelques autres de ses affluents, nous avons pu constater un très haut pourcentage de minéraux lourds opaques. A cause de ce fait et à cause des différences insignifiantes dans le spectre des minéraux lourds transparents, nous avons étudié les différentes phases des minéraux opaques. Voici le résultat: les minéraux lourds opaques des sédiments du pléistocène de la Moselle se distinguent clairement de ceux des affluents parce qu'ils contiennent — jusqu'à 50 grain % de la part opaque — des oolites de ferrite. (Origine: formation minette du Luxembourg). Il est ainsi possible de caractériser exactement les sédiments de la Moselle et d'éclairer l'origine des cailloux du pléistocène largement répandus dans la région de la Wittlicher Senke. En dehors de ces arguments géomorphologiques l'analyse de ces sédiments a fourni la preuve que — jusqu'à la période entre le niveau haut et le niveau bas de la terrasse moyenne — la Moselle a traversé la Wittlicher Senke et que, par conséquent, il y a eu deux bras entre Schweich et Mülheim/Lieser, ce qui confirme les idées deGrebe (1881). A l'aide de cette méthode on a pu prouver de plus que le loess répandu dans la Trierer et Wittlicher Talweite provient des sédiments de la Moselle, et a été emporté par le vent.
    Notes: Zusammenfassung In den pleistozänen Sedimenten der Mosel und einiger ihrer Nebenflüsse konnte bei der Untersuchung der Schwerminerale ein sehr hoher Opakanteil festgestellt werden. Aufgrund dieses Tatbestandes und der nur geringen Differenzierung im transparenten Schwermineralspektrum wurden Erzanschliffe hergestellt und die opaken Mineralphasen untersucht. Das Ergebnis war: der Anteil der opaken Schwerminerale der pleistozänen Moselsedimente (HöT-NT) läßt sich eindeutig von denen der Nebenflüsse unterscheiden, da bis zu 50 Korn% des Opakanteils der Moselsedimente Brauneisenooide (Herkunft: Luxemburgische Minetteformation) führen. Damit ist der Schlüssel zur eindeutigen Charakterisierung von Moselsedimenten und zur Lösung der Frage nach der Herkunft der weitverbreiteten Schotterfluren im Bereich der Wittlicher Senke gegeben. Die Untersuchung der Vorkommen lieferte neben den geomorphologischen Anhaltspunkten den Beweis, daß die Mosel bis in die Zeit zwischen OMT und UMT auch durch die Wittlicher Senke (= Wittlicher Talweite) geflossen ist und somit eine Stromspaltung der Mosel zwischen Schweich und Mülheim/Lieser bis zu dieser Zeit bestanden hat. Dadurch wird eine alte Vermutung vonGrebe (1881) bestätigt. Zusätzlich konnte mit dieser Methode nachgewiesen werden, daß der in der Wittlicher und Trierer Talweite verbreitete Löß aus den Moselsedimenten ausgeweht wurde.

    Description / Table of Contents: Abstract Hydrocarbon exploration in the Molasse basin and the Alpine thrust belt has provided new information on the tectonic structure of the foreland margin of the overthrust belt. Two N-S cross-sections show the front of the Folded Molasse as a so-called Triangle Zone in the area north of the Hindelang 1 well (Bavaria) and the Sulzberg 1 well (Vorarlberg). The Triangle Zone was described and defined byJones (1982) for the Alberta Foothills in Canada. Oil and gas wells commonly encountered overpressured zones with pressure gradients up to 2.5 bar/10 m. The pressure profiles from the Sulzberg1, Hindelang1, Staffelsee1, Miesbach 1 and Bromberg 1 wells were analysed stratigraphically and lithologically with respect to the tectonics of the region. It can be concluded that the overpressures in the Foreland Molasse were caused by compaction, where those within the thrust belt were caused by tectonics.
    Abstract: Résumé Les travaux d'exploration entrepris par l'industrie du pétrole dans le bassin molassique et dans la bordure septentrionale des Alpes ont conduit à de nouveaux résultats en ce qui concerne les structures tectoniques de cette région. Dans deux profils nord — sud établis dans la région, respectivement au nord de Hindelang (Bavière) et au nord de Sulzberg (Vorarlberg), le front de la molasse plissée se présente comme une »zone triangulaire« du type défini parJones (1982) dans les Foothills d'Alberta au Canada. Des forages pétroliers profonds ont fréquemment recontré des pressions interstitielles hyperhydrostatiques avec des gradients pouvant atteindre 2,5 bars / 10 m. Les profils de pression relevés dans les sondages de Sulzberg 1, Hindelang 1, Staffelsee 1, Miesbach 1 et Bromberg 1 ont été analysés au point de vue stratigraphique et lithologique et placés dans le cadre tectonique de la région. Il en résulte que les surpressions dans la molasse d'avant-pays (Vorlandmolasse) sont dues à la compaction et que celles des formations recouvertes par les nappes sont d'origine tectonique.
    Notes: Zusammenfassung Die von der Erdöl- und Erdgasindustrie im Bereich des Alpennordrandes durchgeführten Untersuchungsarbeiten brachten neue Ergebnisse zum tektonischen Bau. So stellt sich in zwei N-S-Profilen nördlich von Hindelang (Bayern) und über die Tiefbohrung Sulzberg 1 (Vorarlberg) die Stirn der Faltenmolasse als Triangelzone dar, wie sie von Jones (1982) aus den Foothills der Rocky Mountains beschrieben wird. Tiefbohrungen auf Erdöl und Erdgas haben verbreitet überhydrostatische Porendrücke mit Gradienten bis 2,5 bar/10 m angetroffen. Es wurden Druckprofile aus den Bohrungen Sulzberg 1, Hindelang 1, Staffelsee 1, Miesbach 1 und Bromberg 1 nach stratigraphisch-lithologischen Gesichtspunkten analysiert, regionaltektonisch zugeordnet und interpretiert. Es zeigt sich, daß die Überdrücke in der Vorlandmolasse durch Kompaktion entstanden sind, während diejenigen unter den Decken tektonische Ursachen haben.
