Olfaction may play an important role in regulating bird behavior, and has been suggested to be involved in feather-pecking. We investigated possible differences in the body odors of red junglefowl females by using an automated olfactometer which assessed the ability of trained mice to discriminate between the odors of uropygial gland secretions (the main carrier of potential individual odors in...
The implementation of light-driven catalytic processes in biocatalysis opens a golden window opportunities. We hereby report the merging photocatalytic C?C bond formation with enzymatic asymmetric reduction for direct conversion simple aldehydes and acrylates or unsaturated carboxylic acids into chiral ?-lactones. Tetrabutylammonium decatungstate (TBADT) is employed as photocatalyst to trigger ...
Mn(II) salen complex immobilized on nano silicagel was prepared by incorporating Mn(II) salen complex into a nanosilica matrix and characterized by TGA, XRD, atomic absorption spectroscopy and was successfully applied as catalyst for the oxidation of alcohols. Oxidation of a series of alcohols in acetonitrile over immobilized Mn(II) salen complex using tetrabutylammonium peroxymonosulfate (TBAO...
A consideration of dissociation of aliphatic carboxylic acids and corrosion inhibition for aluminum.
An alternative method for the synthesis of acetamidobenzimidazoles (3-6) has been developed, including reacylation methylbenzimidazol-2-ylcarbamate (carbendazim, MBC, 1) under action aliphatic and aromatic carboxylic acids. It was shown that with an increase in size alkyl group reaction temperature (in case butyric acid), due to decomposition resulting product, yield target acyl products sharpl...
Organic acids from w heat ( Triticum aestivum), rye (Secale cereale), and barley (Hordeum vulgare, var. “G erbel” and “ Igri” ) were analysed by gas c h ro m a to g ra p h y -m ass spectrom etry. Two carboxylic acid fractions were obtained by chrom atography on Sephadex LH 20: frac tion A contained m ainly aliphatic acids, fraction B contained m ainly arom atic acids. The identified com pounds...
[1] Submicron atmospheric aerosol samples were collected during the International Consortium for Atmospheric Research on Transport and Transformation (ICARTT) 2004 campaign on four platforms: Chebogue Point (Nova Scotia, Canada), Appledore Island (Maine), the CIRPAS Twin Otter over Ohio, and the NOAA R/V Ronald H. Brown in the Gulf of Maine. Saturated aliphatic C-C-H, unsaturated aliphatic C=C ...
