    Notes: A miniaturization of the enrichment serology method for the detection of Salmonella was improved in order to make the technique more reliable, cheaper, and faster. the miniaturized method (“Micromethod”) was compared to the Sperber and Deibel's method (“Macromethod”) and with a classical isolation method; 1062 samples including 700 rearing farms environment samples, 247 poultry meat samples, and 115 nonfat dry milk samples were analyzed. Specificity of both enrichment serology methods was about 92–99.4%. Sensitivity of Micromethod was better than that of the Macromethod for the environmental samples (86.8 and 74.1%, respectively) and the poultry meat samples (87.5 and 77.5%, respectively) but was the same for the nonfat dry milk samples (82.5%). the costs of both methods were respectively 0.43 US $ for the Macromethod and 0.20 US $ for the Micromethod. This “Micromethod” could be proposed for the screening of Salmonella positive batches in the food industries.

    GRAIN SIZE OF TURBIDITE RIPPLES (1969)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 13 (1969), S. 0 
    Details

    Notes: Many, but not all, current ripples show log-normal grain-size distribution and good sorting (P. D. Trask). A range in medians was measured from fifty to several hundred microns. Turbidite ripples are log-normal, very well-sorted and are restricted to medians of very fine sand to silt (〈 130 μ) because the particles have been supplied in suspension at rippling velocity. Experimental suspension current ripples formed at about 50–60 cm/sec are similar in composition and structure to turbidite ripples. The continuous supply results in climbing ripples. The restricted grain size and the internal structure of turbidite ripples both form strong evidence against the action of normal currents. The number of grain-size analyses is still rather small.
