    Notes: Environmental effects of feedlot location and related land disposal operations can be minimized if proper knowledge of hazardous conditions are known and appropriate protective steps taken. Common guidelines often do not apply because of differing physical characteristics of local areas.Analyses of various parameters within a soil profile beneath a feedlot revealed none of the chemical constituent present in high concentrations below the 23-foot depth. In areas where shallow ground water was less than 5 feet from the surface, the ground water was found to be affected by the feedlot. Other hazardous areas in feedlot location are flood-prone areas, areas of surface bedrock, and areas of excessive slope.For land disposal operations, loading rates and frequency of application of feedlot waste should be adjusted in accordance with soil permeability, depth to ground water, and irrigation practices to minimize detrimental effects on ground-water quality.

    Description / Table of Contents: Transition Metal Carbyne Complexes, XVPhenylcarbyne as well as Methoxyphenyl-, (Dimethylamino)phenyl-, and Aminophenylcarbene as Ligands in Cationic or Neutral Complexes of the Type π-ArCr(CO)2LComplexes of the type π-ArCr(CO)3 1a-d are converted into the carbene complexes π-ArCr(CO)2-[C(C6H5)OCH3] 2a-d by treatment with phenyllithium followed by alkylation. On treatment with boron trichloride 2a-d yield the cationic carbyne complexes of the general formula {π-ArCr(CO)2[C(C6H5]}⊕[BCl4]⊖ 3a, c, d Aminolysis with ammonia or dimethylamine leads to the aminocarbene complexes π-ArCr(CO)2[C6H5)NR2] 4 and 5 which are not obtainable by direct aminolysis of 2a-d. These diamagnetic complexes, some of which are very thermolabile, were characterized by i. r., H n. m. r., and 13C n. m. r. spectroscopy.
    Notes: Aus Tricarbonyl-Aromaten-chrom(0)-Komplexen π-ArCr(CO)3 1a-d lassen sich durch Umsetzung mit Phenyllithium und anschließende Alkylierung die Carbenkomplexe π-ArCr(CO)2-[C(C6H5)OCH3] 2a-d darstellen, deren Reaktion mit Bortrichlorid zu kationischen Carbinkomplexen der allgemeinen Formel {π-ArCr(CO)2[C(C6H5]}⊕[BCl4]⊖ 3a, c, d führt. Bei der Aminolyse der kationischen Komplexe mit Ammoniak oder Dimethylamin entstehen - durch Aminolyse von 2a-d nicht zugängliche - Aminocarbenkomplexe π-ArCr(CO)2[C6H5)NR2] 4 und 5. Die diamagnetischen, teilweise sehr thermolabilen Verbindungen werden durch IR-, 1 H-NMR-und 13C-NMR-Spektren charakterisiert.

    Description / Table of Contents: Comparative examinations on gold layers applied on silver. By electrolytical deposition, high vacuum evaporation and cladding gold layers of 10-20 μm thickness had been produced on silver. These layers had been examined in their initial state and after different heat treatments on air by a light microscope and a scanning electron microscope. The microhardness of these layers had also been determined and the diffusion between gold and silver had been studied with the electron microanalyzer. Besides the known features of surface structure and hardness certain differences in the tarnishing and diffusion behaviour had been detected. The cause of these differentiations is primarily due to typical processing features.
    Notes: Durch elektrolytische Abscheidung, Hochvakuumbedampfung und Walzplattierung wurden 10-20 μm dicke Goldschichten auf Silber hergestellt. Die Schichtwerkstoffe wurden licht- und rasterelektronenmikroskopisch im Ausgangszustand und nach verschiedenen Wärmebehandlungen an Luft untersucht. Daneben wurde die Mikrohärte der Schichten ermittelt und mit einer Elektronenstrahlmikrosonde die Diffusion zwischen Gold und Silber studiert. Es haben sich neben den bekannten Merkmalen der Oberflächenstruktur und der Härte gewisse Unterschiede im Anlauf- und Diffusionsverhalten gezeigt. Die Ursache dieser Differenzierungen ist in erster Linie auf typische Verfahrensmerkmale zurückzuführen.

    Notes: Katalytische Heterogen-Hydrierungen in Lösung werden mit elektrochemischen Hydrierungen an Kathoden mit hoher Wasserstoff-Überspannung verglichen. Die katalytische Hydrierung läuft nach einem radikalischen Mechanismus ab, wobei adsorbierte H-Atome als zentrales Zwischenprodukt auftreten. Sie sind im allgemeinen zugleich potentialbestimmend. Die Messung des Katalysator-Potentials erlaubt also Aussagen über die Aktivität aH. Bei der elektrochemischen Hydrierung werden aus dem Substrat bei negativen Potentialen primär Radikalanionen generiert, die nach einem ionischen Mechanismus zum Hydrierungsprodukt abreagieren. Sie ergänzt die katalytische Hydrierung, z. B. bei gewissen Partialhydrierungen und stereochemisch. Auch die beiden Fälle, bei denen die katalytische Hydrierung elektrochemisch an Katalysator-Elektroden bzw. die elektrochemische Hydrierung nach der katalytischen Methode durchgeführt wird, sind gut bekannt. Die Frage, ob Elektrolyse-Wasserstoff für Gasphasen-Hydrierungen wirtschaftlich sein kann, wird abschließend noch kurz diskutiert.
