PublicationArticle A Tertiary Trisomic in Barley (Hordeum vulgare L.)(1977) Ganesh PrasadTertiary trisomics which occur in the selfed progeny of interchange heterozygotes, have gained considerable importance in genetics and breeding of barley. Ramage and Tuleen (1964) proposed the use of ‘Balanced Tertiary Trisomics’ (BTT) for maintaining lines of lethal and sterile genes. The concept of ‘Hybrid Barley’ production through the use of BTT was given by Ramage (1963, 1965) and a hybrid barley variety was released in U.S.A. (Ramage and Wiebe 1969). The present paper reports a tertiary trisomic which was isolated from the progeny of a gamma-ray induced translocation T 2-6 in barley. © 1977, Japan Mendel Society, International Society of Cytology.

Srivastava[No abstract available]PublicationArticle Pulmonary embolism in rheumatic heart disease(1973) A.N. Rai; S.S. Singh; A.P. PandeyPulmonary embolism is a known complication of phlebothrombosis affecting venous system of legs, pelvis and abdomen. Smith et al. (1965) reported that the commonest site of thrombus formation is leg veins (46%), followed by right atrium (38%), inferior vena cava (19%), pelvic veins (16%) and right ventricle (4%), in the order of frequency. Though pulmonary embolism may occur in apparently healthy individuals (Homan, 1943 and Short, 1952), heart disease patients are more at risk (Carlotti et al., 1947, Short, 1952, Byrne, 1960, Sasahara et al., 1967). Sasahara et al. (1967) found that 69% of their cases of pulmonary embolism had cardiac disease, 21% of whom had rheumatic mitral disease. In an earlier study by Sasahara (1965), 50% of the cases of pulmonary embolism were found to have rheumatic heart disease. The present work was undertaken in order to study different aspects of pulmonary embolism in rheumatic heart disease.PublicationArticle Unilaterally regressing retinoblastoma with massive optic nerve involvement in a bilateral lesion(1974) K.S. Mehra; I.M. GuptaAn interesting case of a child having active stage of retinoblastoma in the right eye, with regressed tumor in the left eye but having active continued lesion in the optic nerve of the left eye is reported. The bone marrow biopsy showed presence of malignant cells (evidence of general metastasis) though clinically general metastasis was absent.PublicationArticle Synthesis and structural studies of some first row transition metal complexes of salicylaldehyde hydrazone(1979) R.C. Aggarwal; N.K. Singh; R.P. Singh[No abstract available]PublicationArticle Adrenal steroids and hypothalamo-pituitary-gonad axis(1978) A.K. Mukhopadhyay; F.A. Leidenberger[No abstract available]PublicationArticle On the role of grain-boundary migration during the creep of zinc(Kluwer Academic Publishers, 1973) Vakil Singh; P. Rama Rao; D.M.R. TaplinConstant engineering strain-rate tensile tests have been carried out in the temperature range 20 to 150‡C on high purity Zn, Zn-0.14 at. % Cu (alloy C) and Zn-0.16 at. % Al (alloy A) alloys. Measurements of angular distribution of orientations of grain boundaries have been used to study grain-boundary migration during deformation. Significant cavitation, with increasing propensity at higher test temperatures, occurred in the two alloys but not in pure Zn. A striking feature of the observations in pure Zn and alloy C, as the test temperature was raised, was the formation and subsequent decay of a diamond pattern of uncavitated grain boundaries, a majority of which were preferentially aligned at ∼ 45‡ to the stress axis. By comparison the changes in the angular distribution of grain boundaries was least marked in alloy A. Cavitation was observed in alloy C to maintain grain boundaries in the 45‡ orientation. At the test temperature of 150‡C alloy C, which was prone to the formation of diamond grain-boundary configuration, developed much larger volume fraction of cavities than alloy A. These results are discussed in terms of the different distribution coefficients of Cu and Al in Zn, the different rates of grain-boundary migration in pure Zn and the two alloys and the differences in the substructural features (cells) formed during high-temperature deformation. © 1973 Chapman and Hall Ltd.PublicationArticle Determination of atmospheric turbidity parameters over the north and central India(Springer-Verlag, 1971) Murari Lal; H.S. RathorThe method introduced by Ångström [1, 2] has been adopted for evaluating the atmospheric turbidity parameters, namely wavelength exponent α0 and turbidity coefficient β0 at a number of stations in the north and central India from the pyrheliometric measurements of direct solar radiation for entire spectrum and for specified spectral regions using Schott filters. The optical clarity of the atmosphere over India and the probable size distribution of the aerosols therein have been discussed here on the basis of the inference drawn from these parameters. The annual variations in α0 and β0 have been correlated with the size distribution and the concentration of the dust particles in the atmosphere and the onsets and withdrawls of monsoon. © 1971 Springer-Verlag.PublicationArticle Model pseudopotential and lattice dynamics of lead(1973) B. Prasad; R.S. SrivastavaA local model pseudopotential has been used to compute the phonon frequencies, specific heats and Debye temperature Theta of fcc lead. The computed results are compared with the experimental data. A satisfactory agreement has been found between theory and experiment. Kohn anomalies are seen in the calculated phonon dispersion curves.PublicationArticle Succession of fungi on decaying Setaria glauca Beauv.: A qualitative analysis of the mycoflora(Oxford University Press, 1973) P.D. SharmaThe mycoflora recorded on the decaying shoots of Setaria glauca, from their early senescence onwards, has been analysed qualitatively. On the basis of time of appearance and sporing and duration periods of fungi, three patterns of colonization have been recognized. The group I members, designated as primary colonists appear on shoots just after their senescence during August. This group includes six dematiaceous hyphomycetes and two sphaeropsidales. These are followed by group II members during the late rainy season, and group III members that appear only for a short period during winter. The dominant forms of group II are, 15 dematiaceous and 3 tuberculariaceous hyphomycetes, 2 sphaeropsidales, and 1 ascomycete, whereas those representing group III are, 27 dematiaceous, 2 moniliaceous and I tuberculariaceous hyphomycetes, 5 sphaeropsidales, 1 melanconiales, and 3 mycelia sterilia.These studies also showed that about 94 per cent of the total mycoflora is constituted by the deuteromycetes of which 12 are sphaeropsidales, 1 melanconiales, 78 moniliales, and 3 mycelia sterilia. The moniliales are represented by 3 species of moniliaceae, 69 of dematiaceae, and 6 of tuberculariaceae. The phycomycete stage was absent, the three mucorales being discovered only by inoculation at an advanced stage of decay. The deuteromycetes, particularly dematiaceous hyphomycetes, have been found to play the most important role in this phase of decomposition. © 1973 OXFORD UNIVERSITY PRESS.
