    Notes: Summary The degree of genetic divergence using Mahalanobis's D2 statistic and the clustering pattern using canonical variate analysis between Sahiwal and its 39 Friesian grades were studied for 9 characters of economic importance. The records were adjusted for the significant effects due to farms, periods and seasons. Forty grades were grouped into 11 clusters. The results have shown that in cattle when two breeds of diverse origin, one of superior merit and the other relatively inferior, are crossed in a scheme of forward crossing, there is no linear increase in production level above 50% with the increase in genes of the superior parent. It can not be assumed that grading up to a total replacement of genes will lead to higher levels of production at least in cattle. In order to stabilize a breed type from such a crossbred population a breeding plan has been proposed.

    BERYLLIUM IN ENVIRONMENTAL AIR, WATER AND SOIL (1997)
    Springer
    Water, air & soil pollution 95 (1997), S. 133-146 
    Details
    ISSN: 1573-2932
    Keywords: beryllium ; environment ; air ; water ; soil
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract The study was specifically aimed to obtain concentration of beryllium in various environmental matrices such as air, water and soil in the vicinity of the Beryllium Metal Plant situated at Turbhe, New Bombay. Two analytical techniques – Morin fluorescence method and Atomic Absorption Spectrophotometry using graphite furnace were standardised for beryllium estimation. The beryllium concentration in the natural matrices studied – air, water and soil were in the range of 0.41–0.43 ng m-3, 0.01–0.02 ng mL-1 and 325–767 ng g-1 respectively.
