    Notes: [Auszug] The Ooty array (for details, see refs 3 and 5), normally operated with 18 mirrors, was split up and operated at two sites, site A and site B, 11 km apart. At site A, eight large mirrors, with a diameter of 1.5m, were used and at site B, 10 small mirrors, with a diameter 0.9 m were used. For some of ...

    Notes: [Auszug] BATSE7 on the Compton Observatory has been in operation since 21 April 1991. Here we report on a burst that occurred on 11 July 1991 at 9.53 UT with features not seen previously. The location of this burst derived from relative rates from the triggered detectors is right ascension a = 14 h 30 min ...

    Notes: [Auszug] The apparatus consists of four 20-cm deep liquid scintillation detectors, each 1 m2 in area located at the corners of a square of side 11m. Each scintillator is viewed by a RCA 8575 photo-multiplier with the associated electronics set at a threshold of 0.33 of the average pulse height for a ...

    Genetic divergence in various Sahiwal x Holstein crossbred grades (1979)
    Springer
    Theoretical and applied genetics 54 (1979), S. 69-74 
    Details
    ISSN: 1432-2242
    Keywords: Divergence ; Grades ; Forward crossing ; Canonical root
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    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.

    Polymorphism of mitochondrial DNA (mtDNA) in cattle and buffaloes (1990)
    Springer
    Biochemical genetics 28 (1990), S. 311-318 
    Details
    ISSN: 1573-4927
    Keywords: Bos indicus ; buffalo mitochondrial DNA ; restriction endonuclease
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Mitochondrial DNA (mtDNA) from two breeds of cattle, viz., [Hariana (Bos indicus), Holstein (Bos taurus)] and Indian water buffalo (Bubalis bubalus), was analyzed using 13 restriction endonucleases which recognized an average of about 40 six-base sites. Polymorphism among cattle was detected with six of these enzymes. The two Holstein differed at six sites, whereas the Hariana breed (Bos indicus) did not show any site polymorphism. Surprisingly, the Hariana type differed by only one site from one of the Holstein types. The total size of buffalo mtDNA was estimated to be 16.4 kb. Polymorphism within the Murrah buffalo breed was observed with respect to aBglI site. Scarcely any of the restriction fragments of buffalo mtDNA matched those of cattle mtDNA.

    LEACHABILITY AND IMMOBILISATION OF BERYLLIUM FROM SOLID WASTE (RED-MUD) GENERATED IN PROCESSING BERYL (1997)
    Springer
    Water, air & soil pollution 94 (1997), S. 297-306 
    Details
    ISSN: 1573-2932
    Keywords: Beryllium ; solid waste ; red mud leachability ; immobilisation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract In view of the toxic nature of Beryllium and its compounds the disposal of waste materials containing beryllium needs prior evaluation. The present study was undertaken to obtain information on the leachability and immobilisation of beryllium from solid waste red-mud generated in processing Beryl at the Beryllium Metal Plant at Vashi, New Bombay. The studies showed that 62% of the total beryllium in red-mud can be extracted by water by repeated leaching over a period of 445 d. The mixing of the waste material with cement and casting into cement blocks reduced the leachability of beryllium to 0.11% which got further reduced to 0.02% by thermal curing of cement blocks.

    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.
