    Notizen: Abstract The band structures of121, 123I nuclei have been studied using a version of the particle-rotor-model in which the experimental excitation energies of the neighbouring (A-1) cores can be fed directly as input parameters. The calculations have been carried out with axially symmetric Nilsson potential with both prolate and oblate deformations. The parameters of the model have been chosen from earlier theoretical work and experimental odd-even mass differences. Only the Coriolis attenuation factor has been treated as adjustable parameter. The theoretical band structures are in very good agreement with the available experimental data.

    Notizen: Abstract The level structure of104Ag has been studied through the103Rh (α, 3nγ) reaction at Eα=40 and 45 MeV. The principal features of the proposed level scheme are in agreement with those obtained earlier through heavy ion reaction. Two quasiparttcle-plus-rotor model calculation has been performed, and the results are compared with experimental data.

    Utility of phyllosphere N2-fixing micro-organisms in the improvement of crop growth (1982)
    Springer
    Plant and soil 68 (1982), S. 55-67 
    Details
    ISSN: 1573-5036
    Schlagwort(e): Klebsiella ; Nitrogen fixation ; Oryza sativa ; Phyllosphere ; Rice

    Notizen: Summary The beneficial effect of spraying some highly active phyllosphere N2-fixing microorganisms on high and low yielding cultivars of rice plants as compared with that of urea applied at different doses are described. The dry weight, N-content, 1000 grain weight, and yield were remarkably increased in all cases with the application of phyllosphere microorganisms. The performance of two isolates KUP4 and KUPBR2 with IR-8 and IR-26 rice, was better than that of 52 kg urea-N per hectare. IR-579 rice leaves in association with some phyllosphere bacteria reduced acetylene at the rate of 664–816 nmoles/g leaf/h. In IR-26 rice the effect of application of bacterial suspension at three phases of plant growth corresponded very well with that of urea application in three split doses under identical conditions. Recommended fertilizer rates produced the same yield as the half dose plus bacterial spray in the cultivars Pankaj and Rupsail. Fertilizer application in Pankaj and Rupsail rice reduced nitrogenase activity and the beneficial effects of phyllosphere N2-fixation was reduced by 40–55%.

    Utility of some nitrogen-fixing microorganisms in the phyllosphere of crop plants (1981)

    Notizen: Summary The utility of spraying some known N2-fixing microorganisms on rice leaves grown both in N-less sand culture and under field conditions was examined. The effect was compared with that of spraying a phyllosphere N2-fixing isolate of Klebsiella, KUPBR2, and application of nitrogenous fertilizers. All the growth parameters studied including dry weight and N-content were enhanced. Under field conditions number of tillers was increased by 26% withKlebsiella pneumoniae M5al and by 65% with Aphanothece. The dry weight of the plants was enhanced by 61–119%. The yield per 10 m2 was almost doubled with Aphanothece, Beijerinckia 8007,Mycobacterium flavum, K. pneumoniae M5al and KUPBR2. The increases observed withStreptomyces sp. G12 though less spectacular was significant at 1% level with respect to several growth parameters.K. pneumoniae M5al,M. flavum andStreptomyces sp. G12 exhibited nitrogenase activity both in laboratory culture and in association with rice plants.

    Notizen: Summary Five highly active N2-fixing strains of Klebsiella isolated from the phyllosphere of tropical plants, KUPBR1, KUPBR2, KUPM, KUP4 and KUP6 along withAzotobacter vinelandii OP,A. chroococcum G40 andDerxia gumnosa were sprayed on the foliage of a high yielding wheat cultivar, Kalyansona. The strains of Klebsiella enhanced dry wt., chrorophyll and nitrogen content, and 1000 grain weight. Grain yield in inoculated plants varied between 19.9 and 25.09 quintals ha−1 against 24.34 quintals with urea. Best results were obtained with KUP4 which when applied at half dose was as effective as 52.5 kg Urea-N ha−1. Azotobacter and Derxia only slightly improved growth and nitrogen content of grain or straw.

    Notizen: The infrared spectra of alkaline jute stick have been discussed and compared to that of untreated and control sample. A higher shift in the O—H and lower shift in the C—H stretching frequencies were observed in alkaline sample. The presence of a strong band at 1440-1430 cm-1 may be due to the coupling of COO- frequency with CH2 deformation frequency. The C—O stretching mode at 1240 cm-1 disappears on alkaline treatment with the formation of new peaks at 1265 and 1225 cm-1. The β-glucosidic band at 895 cm-1 is shifted to 880 cm-1 with doubled intensity in alkaline jute stick.

    Notizen: Defatted jute stick was treated with sodium hydroxide solution (2% w/v) at ambient temperature (∼ 32∼C) and boiling water bath temperature (95-97°C). Infrared (IR) spectra of defatted jute stick and alkali-treated jute stick were studied. The IR spectra of the alkalitreated jute stick were conspicuous by the absence of the 1730 cm-1 band, as compared to that of jute stick. Another characteristic feature of the alkali treated jute sticks is the absence of the band at 1240 cm-1, which is replaced by the 1265 and 1225 cm-1 bands; other bands in the above samples also recorded significant changes.

    Notizen: Jute fiber was grafted by acrylonitrile and methylmethacrylate monomers in raw and bleached condition. It was also noted that optimum grafting takes place after about 4 h of grafting. It was also noted that in bleached jute fiber, the grafting percentage is higher at all stages of grafting but the tenacity value at the highest add-on is practically the same as that of raw fiber with much less add-on. The crystalline orientation of the grafted jute fiber was correlated with the fiber tenacity. The moisture regain (%) of the fiber after grafting showed a decreasing trend with an increase in grafting percentage. No structural change of the fiber occurred due to grafting. © 1995 John Wiley & Sons, Inc.

    Notizen: Jute stick was treated with white-rot fungus for incubation periods of 6 days (MBA) and 12 days (MBB). The infrared spectra of fungus treated samples (MBA and MBB) and control jute stick (MBC) were analyzed and compared. The bands attributed mainly to hemicellulose show an increase in absorbance intensity ratios (Aν/A2900) with increase of incubation time. Similarly the bands attributed to lignin show an increase in the absorbance intensity ratios with increase of incubation time. Increase in the intensity of 1635 cm-1 band with increase of incubation time was also observed.
