    Effect of bottlegourd seedcoating with antagonists on seedlings, quantum of the pathogen inside the seedlings and population of the soil againstFusarium oxysporum (1987)

    Notes: Abstract Bottlegourd seedlings raised from antagonists coated seeds did not show any wilting symptoms and remained completely healthy. The pathogen quantum inside the host tissue was found least. The pathogen propagules per gram of host tissue were restricted and the soil population of theFusarium oxysporum was reduced very much in antagonists introduced soil.

    Modeling of the heat-transfer process in a differential scanning calorimeter (1992)

    Notes: The model developed predicts a priori potential errors associated with the energy trace recorded by an isoperibol differential power scanning calorimeter in the measurement of heat of adsorption of H2 on Pt and Pd catalysts. The uptake of H2 by the catalyst sample was approximated by a diffusion-limited quasi-steady-state moving boundary model. This approximation is valid only if the parameter [(adsorption capacity of cat. sample)/(inlet conc. of H2)] is extremely large (∼ 24). The effect of flow rate, amount of H2 adsorbed, sink temperature, and the thermal conductivity of the adsorbate mixture was examined. Model predictions indicate that the error in the energy trace recorded by the DSC is appreciable: if a large difference exists between the thermal conductivity of the inert carrier, Ar (K = 0.017 J/m·K·s), and the adsorbate, H2 (k = 0.174 J/m·K·s); if the heat sink temperature is much lower (∼ 90 K) than the measurement temperature. However, these errors can be eliminated by matching the thermal conductivity of the inert carrier and adsorbate, such as He (k = 0.143 J/m·K·s) and H2 (k = 0.174 J/m·K·s). The results agree well with the experimental observations of Vannice et al. (1987) on high-purity Pt and Pd powder and supported Pt catalysts, if the H2 uptake by the catalyst sample in the calorimeter is small (≤2 μmol).

    Description / Table of Contents: Nitrosyl-Rhenium-Komplexe: Darstellung, Eigenschaften und Struktur von Acetylacetonato-DerivatenEinige neue Rhenium-Komplexe, wie [Re(NO)(acac)2(Cl)H2O] und Re(NO)(acac)3(acacH)(H2O)2 wurden durch Umsatz von Re(NO)Cl3 · H2O bzw. Re(NO)(OH)3 · H2O mit Acetylaceton dargestellt. Ferner wird die Darstellung von [Re(NO)(py)(acac)2(Cl) · H2O], [Re(NO)(acac)(OH)(Cl) · H2O], [Re2(NO)2(acacH)3(acac)2 · Cl4], [Re(NO)(acac)2(OH) · H2O] · 2 H2O angegeben.

    Notes: Some new complexes of rhenium containing monocoordinating acetylacetone viz. [Re(NO)(acac)2(Cl)H2O], Re(NO)(acac)3(acacH)(H2O)2 have been synthesized by reacting acetylacetone with either Re(NO)Cl3 · H2O or Re(NO)(OH)3 · H2O. The preparation of [Re(NO)(py)(acac)2(Cl) · H2O], [Re(NO)(acac)(OH)(Cl) · H2O], [Re2(NO)2(acacH)3(acac)2 · Cl4], [Re(NO)(acac)2(OH) · H2O] · 2 H2O have also been described. These complexes were characterized through their elemental analyses, u.v., vis, i.r., 1Hn.m.r., magnetic, and conductance data.

    Notes: 13C NMR data for 1,6-bis derivatives of hexa-2,4-diynes are reported. Introduction of a sulphone or sulphoxide moiety at C-1, C-6 in place of sulphide, ether or amino groups caused a 6-7 ppm upfield shift (β effect) for the C-2, C-5 carbons and a 3-4 ppm downfield shift (y effect) for the C-3, C-4 carbons.
