Variability between readers in the evaluation of the radiographic appearances of pneumoconiosis has been investigated by several authors. To reduce inter and intrareader variability, standard reference films were introduced for epidemiological purposes. Improved films and methods of classification were published in subsequent years. The category of profusion of small opacities is determined by considering the profusion as a whole over the affected zones of the lung, and by comparing this with the standard radiographs. This requires a mental process of integrating profusion over the affected zones.
The purpose of the present study was to determine whether there would be any …
The Flute Duets Of W.F. Bach: Sources And Dating, Anita Breckbill
The Flute Duets Of W.F. Bach: Sources And Dating, Anita Breckbill
UNL Libraries: Faculty Publications
The six flute duets of Wilhelm Friedemann Bach (1710-1784) are among the finest examples of this genre from the eighteenth century. That they are still not as well known as they deserve to be may stem partly from the problems with the editions that have been available until recently. The question of when these duets were composed has never been completely answered, largely because the sources present a confusing picture. In his classic biography of Wilhelm Friedemann Bach (1913), Martin Falck remarked that Bach is known to have composed pieces for the flute in Berlin (or, in other words, during …
Differential Toxicity Of Enantiomers Of Maackiain And Pisatin To Phytopathogenic Fungi, Leslie M. Delserone, David E. Matthews, Hans D. Vanetten
Differential Toxicity Of Enantiomers Of Maackiain And Pisatin To Phytopathogenic Fungi, Leslie M. Delserone, David E. Matthews, Hans D. Vanetten

Enantiomers of the isoflavonoid phytoalexins maackiain and pisatin were tested for toxicity to 36 fungal isolates representing 19 species. Nine of these species were pathogens of red clover, which synthesizes (–)maackiain; seven species were reported to be pathogenic on garden pea, which synthesizes predominantly (+)pisatin and minor amounts of (–)maackiain. In general, non-host phytoalexins were more inhibitory than host phytoalexins to growth of these pathogens. In addition, the opposite enantiomer of the host phytoalexin was often more inhibitory to a pathogenic fungus than the normally-occurring enantiomer. There was little correlation between the tolerance of fungi to (+) versus (–)pisatin and …
