    Description: Leg 49 of the International Phase of Ocean Drilling (IPOD) was designed with a wide spectrum of problems in mind. Topics investigated were (1) variation with time of mantle sources of spreading-center magmas, (2) aging of the volcanic layer, (3) degree of hydrothermal alteration and metamorphism of the volcanic layer, (4) lateral and vertical variation of the petrochemistry, magnetic properties, and structure of the volcanic layer, (5) north-south variability of spreading-center magmas through the North Atlantic, (6) initiation of glaciation during the late Pliocene, and (7) the influence of bottom currents originating at the Iceland-Faeroes Ridge on sediments of the ridge flank province of the western North Atlantic.

    Description / Table of Contents: Zusammenfassung Ein Vergleich im Frequenzbereich zeigt, daß bei der Berechnung der Verweilzeitverteilung mit dem Dispersionsmodell das endlich begrenzte System für Péclet-Zahlen Pe 〉 10 mit guter Näherung durch ein einseitig unbegrenztes System und für Pe 〉 50 durch ein beidseitig unbegrenztes System ersetzt werden kann.
    Notes: Abstract A comparison in the frequency domain shows that for the determination of the residence time distribution with the dispersion model the finitely restricted system may be substituted with good approximation for Peclet numbers Pe 〉 10 by a one-side unrestricted system and for Pe 〉 50 by a both-side unrestricted system.

    Notes: Summary At concentrations above 10−5 M myelin basic protein (MBP) induced a small inhibition of the uptake of H3-5HT and H3-NA into rat cortex slices. Release of 5HT, NA and Gaba was not affected by 10−5 M MBP.

    Notes: [Auszug] THE North American apparent polar wander (APW) curve for the mid Mesozoic is poorly understood and has been the subject of disagreement for some time. Data have been particularly inconsistent for the Jurassic Period1'2. With relatively few reliable Jurassic determinations it has commonly been ...

    Description / Table of Contents: Zusammenfassung 1. 28 marine Algen aus den Klassen der Chlorophyceen (5 Arten), Phaeophyceen (11) und Rhodophyceen (12) wurden auf das Vorkommen flüchtiger Amine untersucht. 2. Mit Hilfe papierchromatographischer und mikrokristallographischer Methoden konnten insgesamt 9 flüchtige Amine in Algen nachgewiesen werden: Methylamin (MA), Dimethylamin (DMA), Trimethylamin (TMA), Äthylamin (ÄA), Propylamin (PA), Isobutylamin (iBA), Isoamylamin (iAA), 2-Phenyläthylamin (PÄA) und das bisher aus der Natur nicht bekannte 2-Methylmercaptopropylamin (MMPA). 3. Weitverbreitet findet sich bei Algen Trimethylamin (in 23 von 28 untersuchten Arten), während Dimethylamin nur in 2 Arten sicher nachgewiesen werden konnte. Das natürliche Vorkommen von Methylamin ist nicht gesichert, da dieses Amin möglicherweise erst bei der Aufarbeitung aus instabilen Methylaminoverbindungen entsteht. 4. Primäre Amine kommen in Vertretern aller 3 Algenklassen vor, besonders verbreitet jedoch bei Rhodophyceen (7 von 12 Arten). Biogenetisch werden zumindest die primären Amine der Rhodophyceen, mit Ausnahme von Methylamin, durch enzymatische Decarboxylierung aus entsprechenden Aminosäuren gebildet.
    Notes: Summary Twenty-eight species of marine Chlorophyceae (5), Phaeophyceae (11), and Rhodophyceae (12) were examined for the occurence of simple volatile amines. The volatile alkaline constituents of the algal samples were extrated by alkaline steam destillation and separated and identified by paper chromatography and microcristallography. A total of 9 volatile amines were found to occur in the species so far examined: methylamine (MA), dimethylamine (DMA), trimethylamine (TMA), ethylamine (ÄA), propylamine (PA), isobutylamine (iBA), isoamylamine (iAA), 2-phenylethylamine (PÄA), and 2-methylmercaptopropylamine (MMPA). MMPA has not previously been reported to occur in any other plant. The occurence of TMA is widespread in marine algae (23 of 28 sp.) whereas an occurrence of DMA could be demonstrated only in two species. MA, which was found in all algal samples, might be formed from labile methylamino-compounds in the course of preparation. Its coccurrence as a natural constituent of algae remains doubtful. Primary amines could be identified in species of each of the three classes of algae, but an especially widespread occurrence was found in Rhodophyceae. With the exception of MA the primary volatile amines, at least those of Rhodophyceae, arise biosynthetically from the corresponding amino acids by enzymatic decarboxylation.
