    Notizen: Abstract The influence of different methods of N fertilizer application-sub-surface placement (SS) and broadcast application (BC) as a single basal dose of 40 kg N ha−1 of urea (U) and ammonium sulphate (AS)-on fresh weight (FW) and acetylene reduction activity (ARA) ofAzolla pinnata (Bangkok) and yield of rice was studied for consecutive three seasons. The FW, ARA and N yield ofAzolla were significantly superior with SS placement than with BC application. Of the two N sources, AS was superior to U in recording higher FW, ARA and N yield of Azolla irrespective of methods of N application. Crop yield and crop N uptake were higher with SS application alone and in combination with Azolla as compared to that of surface application of N fertilizers. The combined use of AS and Azolla recorded significantly higher crop yield and crop N uptake than that of U combined with Azolla, irrespective of methods of application.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Cu(II)-komplexe von Acenaphthoquinonmono(4-methylquinolinyl)hydrazon (AMH) der allgemeinen Zusammensetzung [CULX2] (mitL= AMH;X=Cl, Br, I, OAc oder NO3) (beim Sulfatokomplex lautet die Zusammensetzung [CuLSO4]2) wurden hergestellt und mittels Elementaranalyse, Messungen des magnetischen Momentes, Konduktivitätsmessungen, IR-, Elektronen- und EPR-Spektroskopie sowie mittels Thermoanalyse beschrieben. Für alle Komplexe wurde eine planare Geometrie nachgewiesen. Die TG-Kurven zeigen eine Zersetzung in einem Schritt, an dessen Ende die Bildung von CU2O steht.
    Notizen: Abstract Cu(II) complexes of acenaphthaquinonemono(4-methylquinolinyl)hydrazone (AMH) of general composition [CuLX2] (whereL=AMH;X=Cl, Br, I, OAc or NO3) with the exception of sulphato complex, where the composition is found to be [CuLSO4]2 have been synthesized and characterized by elemental analyses, magnetic moment measurements, conductivity measurements, IR, electronic and EPR spectral techniques and by thermal analysis. A planar geometry is indicated for all the complexes. TG curves show one step decomposition of complexes and formation of CU2O at the end of the step.

    Rice yields as influenced by Azolla N2 fixation and urea N-fertilization (1989)

    Notizen: Abstract Application of 0, 30, 60, 90 and 120 kg N ha−1 of urea (U) in split doses with (and without)Azolla pinnata, R. Brown was studied for three consecutive seasons under planted field condition. Fresh weight (FW), acetylene reduction activity (ARA) and N yield of Azolla were found to be maximum 14 days after inoculation (DAI). Among the different treatments, maximum Azolla growth was recorded in no N control. The FW, ARA and N yield of Azolla were inhibited increasingly with the increase in N levels. Irrespective of season, FW and N yield of Azolla were inhibited only a small extent with 90 kg N ha−1 U, beyond which the inhibition was pronounced. ARA was inhibited only slightly up to 60 kg N ha−1 of U. Grain yield and crop N uptake of rice increased significantly up to 90 kg N ha−1 of U (alone or in combination with Azolla) in the dry seasons (variety IR 36) and up to 60 kg N ha−1 U in the wet season (variety CR 1018).

    Notizen: Abstract Reaction product cross sections have been measured for reactions of4He projectile with54,56Fe,58Ni and59Co targets in the bombarding energy range 14–27 MeV. The cross-section-weighted average charge $$\overline {\Delta Z}$$ and mass $$\overline {\Delta A}$$ removed from the compound system were deduced and compared with results reported for heavy-ion induced reactions. Variation of $$\overline {\Delta A}$$ with E CN * is independent of the initial angular momentum of compound nucleus in theA=60 mass region in contrary to the rare-earth region. This would suggest a strong angular momentum removal from the compound nucleus by evaporation of particles forA≈60 nuclei. The average evaporated charge $$\overline {\Delta Z}$$ depends on both the CN excitation energy E CN * and the compound nucleusN andZ numbers. The $$\overline {\Delta A}$$ and $$\overline {\Delta Z}$$ dependence on excitation energy and the projectile-target combination can be understood in terms of the statistical model calculations.
