    Notes: Summary A four-variable, a five-variable and a six-variable vector autoregression (VAR) is used in the study to test empirically the linkages among changes in money, outstanding public bonds, interest rates, output, real asset prices, and real investment expenditures in West Germany. After estimating Sims-type and Hsiao-type vector autoregressions the VAR models are the converted to their moving-average representations and the innovation accounting technique is used to examine the impact of changes in asset prices and output on investment behaviour.

    Notes: Abstract Reflection electron energy loss measurements of CuInSe2 single crystals are reported and when possible, the losses are compared with former results by Kazmerski and Jamjoum et al. Their identification of the transitions is confirmed and refined by spectrum simulations with total and partial densities of states from band structure calculations of Jaffe, Bendt, Zunger, and Bullett. New conduction-band maxima at energies not covered by the available calculations, are proposed and their consistency with the experimental loss energies is shown by another simulation with Lorentzian density peaks.

    Description / Table of Contents: Zusammenfassung In zwölf verschiedenen Sorten von Nußnougat-Creme wurde die Fettsäurezusammensetzung einschließlich der trans-Fettsäuren mittels Kapillargaschromatographie untersucht. Die Cremes bestanden hauptsächlich aus Zucker und teilweise gehärteten Pflanzenfetten. In den verschiedenen Sorten betrug der gravimetrisch ermittelte Fettgehalt zwischen 30 und 38,2%. Die verschiedenen Cremes wiesen deutliche Unterschiede in ihrer Fettsäurekomposition auf. Der Gehalt an Linolsäure, der wichtigsten mehrfach ungesättigten Fettsäure, schwankte zwischen 12 und 39%. Der Anteil an Palmitinsäure (16∶0), die den Hauptanteil an den gesättigten Fettsäuren ausmachte, variierte zwischen 9 und 27%. Der Gesamtgehalt an trans-Fettsäuren lag zwischen 0,9 und 12,3%, nur zwei Cremes enthielten weniger als 1 %. 18∶1t stellte den größten Anteil an allen trans-Fettsäuren, während 14∶1t und 16∶1t nur in Spuren gefunden wurden. Drei Proben enthielten die Linolsäure-Isomere 18∶2tt, 18∶2ct und 18∶2tc, jeweils in einem Bereich zwischen 0,7 und 1,06% der Gesamtfettsäuren; in den restlichen Cremes wurden davon nur Spuren nachgewiesen. Unsere Untersuchungen wiesen trans-Fettsäuren in jeder Form von Nußnougat-Creme nach. Da mögliche Zusammenhänge zwischen der Aufnahme von trans-Fettsäuren und der Entstehung von Tumorerkrankungen und Arteriosklerose ungeklärt sind, sollten andere Herstellungsverfahren verwendet werden, um die trans-Fettsäuren aus den genannten Produkten zu eliminieren, zumal diese bevorzugt von Kindern als Brotaufstrich verzehrt werden.
    Notes: Summary The fatty acid composition including trans fatty acids of 12 brands of nut-nougat creams were analyzed by capillary gas chromatography. The creams consisted mainly of sugar and partially hydrogenated vegetable oil. The lipid content, which was quantified gravimetrically, amounted to between 30 and 38.2 % in the different brands. The fatty acid composition varied considerably between the different creams. Linoleic acid, the major polyunsaturated fatty acid (PUFA), ranged from 12 to 39%. Palmitic acid (16∶0), which was the main fatty acid, varied from 9 to 27 %. The total trans fatty acid content of the 12 creams ranged from 0.9 to 12.3 %. Only two of the creams contained less than 1% of trans fatty acids; 18∶1t was the trans fatty acid found in the greatest amounts, whereas 16∶1t and 14∶1t were only found in trace amounts. Three samples had amounts of 18∶2tt, 18∶2ct, and 18∶2tc between 0.7 and 1.06%; only small amounts of linoleate isomers were detected in the other creams. Our results show that trans fatty acids are present in every brand of chocolate cream tested. Since the potential risk of arteriosclerosis and cancer resulting from the consumption of trans fatty acids is not yet clear, different ways of production should be used in order to eliminate them from the creams that are a preferred bread spread of infants and children.
