Microbial metabolites of harman alkaloids.

Several microorganisms showed the ability to transform the harman alkaloids, harmaline (1), harmalol (2) and harman (5). Harmaline (1) and harmalol (2) were converted by Rhodotorula rubra ATCC 20129 into the tryptamines, 2-acetyl-3-(2-acetamidoethyl)-7-methoxyindole (3) and 2-acetyl-3-(2-acetamidoethyl)-7-hydroxyindole (4), respectively. Harman (5) was biotransformed by Cunninghamella echinulat...

Tom George lias an odd kind of picture gallery. All the houses in his street have lean-to pantries, with tiny windows, the upper half glass, the lower latticed wood. It is traditional to keep the family egg-cups on the ledge formed by the wooden bottom of the glass section. Every variety of egg-cup is here displayed?white, red, and blue china, and metal. Occasionally other small, gay articles a...

Spectral changes in the tom-tom related to striking force

This study has investigated the question how the radiated spectra of a tom-tom changes with striking force. Five tom-toms of different size were recorded at four dynamic levels (pp, mp, mf and ff) and their averaged spectra analysed. It was observed that the number of modes excited increase with playing strength, seen in the radiated spectra as a characteristic change in slope for higher freque...
