    Notes: Abstract  Monosomic chromosome addition lines of Brassica oxyrrhina in the background of alloplasmic B. campestris carrying B. oxyrrhina cytoplasm were generated and characterised through morphology, cytology and molecular (RAPD) analysis. Four successive backcrosses of the synthetic alloploid B. oxycamp with B. campestris yielded 24 monosomic addition plants that were grouped into seven different synteny groups based on morphological similarity and RAPD patterns. Each synteny group exhibited morphological features diagnostic for the presence of individual B. oxyrrhina chromosomes including some novel phenotypes. Meiotic studies of the addition lines revealed the homoeology of four B. oxyrrhina chromosomes (synteny groups 1, 3, 5 and 6 ) with B. campestris chromosomes as indicated by trivalent associations, with the highest homoeology (44.23%) in synteny group 1 and the lowest (6.1%) in synteny group 3. Seed fertility of the addition lines ranged from 94.85% (synteny group 1) to 56.98% (synteny group 5). All of the addition lines were male-sterile except synteny group 6 which had 12–16% stainable pollen. Ovule transmission of the B. oxyrrhina chromosomes added to the progenies of addition lines ranged from 23.52% (synteny group 6) to 14% (synteny group 7). RAPD analysis confirmed the validity of synteny grouping based on morphological observations. Approximately 45% of the primers studied were informative, giving B. oxyrrhina-specific RAPD bands unique for each synteny group, except group 6.

    Capillary-Constant Correlations for Some New Refrigerants (1998)
    Springer
    International journal of thermophysics 19 (1998), S. 1473-1484 
    Details
    ISSN: 1572-9567
    Keywords: capillary constant ; refrigerants ; surface tension

    Topics: Physics
    Notes: Abstract This paper presents a method of evaluating the capillary constant of some new refrigerants, namely HFCs 32, 125, 134, 134a, 143a, and 152a; HCFCs 123, 123a, 124, 141b, and 142b in the liquid-vapor coexistence regions except within 2K from the critical point. The correlation is of the form a 2 =a 0 2 (1-Tr)0.92 where a 0 2 is obtained through the saturated-liquid density data. The calculated results show that the correlation is able to predict experimental data within 4% with a maximum absolute deviation less than 9%. A procedure to calculate the surface tension without the saturated vapor density data is also presented.
