    Decreased Gut-associated IgA Levels in Patients with Typhoid Fever (1980)
    Oxford, UK : Blackwell Publishing Ltd

    Notizen: Gut and serum immune responses were studied in twenty-two patients with bacteriologically proved typhoid fever at different stages of the illness and six volunteers after parenteral immunizations with heat-killed typhoid vaccine. Whereas the former group had some specific antibodies in their intestinal aspirates and significant specific antibody responses in their sera, the latter could only mount a serum antibody response. Moreover, the intestinal IgA levels in the patients remained significantly decreased throughout the whole course of the illness, but a rise of IgG and IgM was observed in their jejunal secretions. In contrast, the levels of all the three major classes of serum immunoglobulins IgG, IgM and IgA were raised in the patients, as opposed to the volunteers, in whom only IgG and IgM levels were increased. It was inferred that the subjects with deficit of intestinal IgA, and thus lacking protective mucosal barrier, are more prone to develop typhoid fever.

    Experimental ancylostomiasis in chickens: Effect of various dose of infectiveAncylostoma caninum larvae on their migration and distribution (1983)
    Springer
    Cellular and molecular life sciences 39 (1983), S. 905-906

    Notizen: Summary White leghorn chickens when infected with repeated doses ofAncylostoma caninum larvae, expel the larvae at a faster rate than when infected with a single dose. This suggests that the initial dose induces some resistance in the host. An initial dose of 1000 and 2000 larvae, followed by a 2nd dose of the same order, induces resistance in the alimentary tract causing the entire larval burden either to migrate to other tissues (organs) or to be expelled in 24 h.

    Relationship of serum guanase levels with economic characters in zebu purebred and temperate × zebu crossbred dairy cattle (1981)

    Notizen: Abstract Serum guanase levels of Indian Zebu (Hariana) cattle and its crosses with different exotic levels of temperate breeds of dairy cattle were estimated in 527 animals, and their associations with economic characters were determined. The overall mean value of serum guanase level was 13.46±0.45 IU/ml of serum. An inverse relationship between the concentration of the enzyme and the frequency of cattle falling within a definite range was observed, as over 75% of the animals possessed 1 to 20 IU/ml of serum guanase. An analysis of variance revealed significant differences (P〈0.01) in enzyme levels among different genetic groups under study. Hariana (Zebu) purebreds had significantly higher enzyme levels (19.60±1.85) than any of the crossbred groups, whose enzyme levels ranged from 8.99±1.41 in Red Dane F1 half-breds to 14.30±1.11 in Brown Swiss F1 half-breds. The correlation and regression coefficients were significantly positive for reproductive traits such as age at first service and age at first calving, and significantly negative for production traits such as lactation yield and lactation length. These results suggest that selection of dairy cattle based on low serum guanase levels might result in correlated improvements in dairy cattle productivity.

    Determination of structure parameters using sodar (1982)
    Springer
    Boundary layer meteorology 23 (1982), S. 105-114

    ISSN: 1573-1472
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Geologie und Paläontologie , Physik
    Notizen: Abstract The temperature structure parameter at Delhi has been determined from intensity information of sodar observations for a period of one year at a height of 200 m in the planetary boundary layer applying the moisture correction due to Wesely. It is found that mean monthly values of the temperature structure parameter for stable and unstable conditions are quite different during the monsoon months (July to October) but are rather similar during the other months. The refractive index structure parameter values have been calculated for the dry atmosphere (optical) as well as by applying the moisture correction (radio) due to the Sirkis and Ottersten et al. models. It is found that the dry atmospheric values of the parameter are generally lower than the humidity-corrected values. The sodar-measured values of the parameter under dry atmospheric conditions have been examined in relation to the Hufnagel and Tsvang models.

    The influence of the entrance channel mass asymmetry on the reaction mechanism (1980)
    Springer
    The European physical journal 296 (1980), S. 287-294 
    Details

    Thema: Physik
    Notizen: Abstract We have tried to investigate the influence of the entrance channel mass asymmetry on the reaction mechanisms associated with heavy ion collisions. Two systems, one very much asymmetric (O+Mo) and the other one almost symmetric (Cr+Fe), were studied in detail by measuring evaporation residues, deep inelastic collision products and fission fragments. An important fraction of the fragments observed in the Cr+Fe system exhibits all the characteristics of fission fragments. The analysis of these data seems to indicate that these fission like products are most likely emitted by a long lived composite system having not reached full statistical equilibrium for all the degrees of freedom. As a consequence, the fusion cross section for this symmetric system is too low as compared to predictions based on a critical distance approach for fusion, whereas the asymmetric system (O+Mo) is well understood in term of the same model.

    Life time of the intermediate complex in a deep inelastic collision depends on the mass asymmetry of the entrance channel (1980)
    Springer
    The European physical journal 297 (1980), S. 41-53

    Thema: Physik
    Notizen: Abstract The general trend of the multi differential cross section plots for the products obtained from the dissipation collisions of the three systems, forming almost the same composite systems but with different degrees of mass asymmetry in the entrance channel,52Cr (261 MeV)+56Fe,40Ca (182 MeV)+64Ni and16O (187 MeV)+92Mo, were analysed in the frame of the Diffusion Model, assuming that the intermediate system decays with a statistical life time. A fairly good agreement has been obtained between the calculated multi differential plots and the experimental ones. The half life time of the composite systems seem to depend on the mass asymmetry of the entrance channel.

    A possible mechanism in heavy ion induced reactions: “Fast fission process” (1981)

    Thema: Physik
    Notizen: Abstract The influence of the orbital angular momentuml on the mass distribution of fission fragments is studied, both on previously available data on heavy ion induced fission and in new specifically planned experiments: systems40Ar+165Ho and24Mg+181Ta at bombarding energies ranging from 180 up to 391 MeV and leading to the same fissioning nucleus205At with differentl distributions. Whenl values corresponding to a vanished fission barrier are reached, the mass distribution broadens. This suggest the existence of a specific process, “fast fission”, atl-values intermediate betweenl-values leading to compound nucleus formation and deep inelastic collisions, respectively. This process and its conditions of occurence are discussed; of special interest are the correlated differences between the limitations to the fusion cross-section and the fission mass distributions broadenings, respectively, for the Ar+Ho and Mg+Ta systems.
