    Notes: Abstract The metal-responsivesmt operator/promoter region ofSynechococcus PCC7942 was fused to theluxCDABE genes ofVibrio fischeri. Plasmid DNA (pJLE23) carrying this fusion conferred metal ion-inducible luminescence to transformed cyanobacteria.Synechococcus PCC7942 (pJLE23) was sensitive to ZnCl2 concentrations within a range of 0.5–4 μM as demonstrated by induction of luminescence. Trace levels of CuSO4, and CdCl2 were also detected.

    Search Costs and Price Dispersion in a Localized, Homogeneous Product Market: Some Empirical Evidence (1997)
    Springer
    Review of industrial organization 12 (1997), S. 801-808 
    Details
    ISSN: 1573-7160
    Keywords: Information costs ; price dispersion ; search costs
    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract Convenience stores provide an opportunity to compare the price dispersion that occurs for gasoline, which is characterized by relatively low search and information costs to consumers, with that of in-store items, which are characterized by relatively high search and information costs to consumers. The results obtained from this study support the hypothesis that differences in search and information costs for consumers play a significant role in explaining the observed price dispersion that occurs for homogeneous items sold at convenience stores.
