    Notes: Abstract Some of the measures suggested for amelioration of drought effects include application of N fertilizer and plant growth regulators (PGRs). Since N2-fixing bacteria produce plant growth substances (PGRs), the effect of foliar application of an active strain of Klebsiella sp. (KUPOS) on IR-50 rice was examined using three foliar sprays applied at 10-day intervals. Irrigation once every 3 days was essential for plant growth. Application of KUPOS and 40 kg N ha-1 improved grain yield of acutely water stressed plants from 330 kg ha-1 to more than 1300 kg ha-1 along with an improvement in several growth variables and yield determinants. Indole acetic acid, kinetin and GA3, in a mixture of 10-4 M of each, were less effective than KUPOS in alleviating stress effects. The adverse effects of water stress on respiration and photosynthesis as indicated by CO2 exchange were also alleviated by these treatments. While uptake of K, Mg, Ca, Fe and Mo was increased, Na content decreased, accompanied by an increase in proline content. The order of effectiveness of the treatments was 40 kg N ha-1 〉KUPOS〉PGRs.

    Notes: 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.

    Notes: 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.

    Description / Table of Contents: Es wird über Herstellung und Eigenschaften von NiII- und CuII-Komplexen mit der SCHIFFschen Base „BAPE“ aus Acetophenon und Äthylendiamin sowie über gemischte BAPE/Acetylaceton-Komplexe berichtet (Formeln I-V s. Abstract). BAPE wirkt dabei als zweizähniger Neutralligand. Die Komplexe wurden durch Elementaranalyse, Elektronenspektrum sowie durch magnetische und Leitfähigkeitsmessungen charakterisiert. Für MII(BAPE)Cl2 wird pseudotetraedrische, für [MII(BAPE)(acac)(H2O)2] ClO4 tetragonale Struktur abgeleitet (MII = Ni, Cu). Der Komplex [Ni(BAPE)(acac)]ClO4 erwies sich als quadratisch-planar.
    Notes: Preparation and properties of the following NiII and CuII complexes of the Schiff base derived from acetophenone and ethylenediamine (BAPE) and also of the mixed NiII and CuII chelates with BAPE and acetylacetone (acac-H) are described: In each case the Schiff base, BAPE, acts as a neutral bidentate ligand. The complexes are characterised by electronic spectra, magnetic susceptibilities, conductivities and elemental analyses. Pseudotetrahedral structure is proposed for M(BAPE)C12, while tetragonal structure for [M(BAPE)(acac)(H2O)2]ClO4 (M = Ni and Cu). The complex [Ni(BAPE) (acac)]ClO4 has been found to be square planar.
