    Electrochemical behaviour of some transition metal oxides in molten dimethylsulphone at 150°C (1986)

    Notes: Abstract In view of the possible application in non-aqueous líthium cells operating at relatively high temperatures, molten dimethylsulphone (DMSO2) has been used as the electrolyte solvent in lithium cells at 150°C. The stability of lithium in molten DMSO2 has been found to be good as compared with that observed in organic solvents such as propylene carbonate, thus indicating that the Li+/Li system can be used as a suitable reference electrode in this medium. The electrochemical behaviour of some transition metal oxides has been investigated in LIClO4 solutions in molten DMSO2. The results obtained from voltammetric and chronopotentiometric measurements have shown a satisfactory behaviour for all the cathodic materials tested. Moreover, electrochemical insertion of Li+ ions into the crystal lattice of these oxides is a very fast process. Thus molten DMSO2 appears to be a very interesting organic solvent usable in high energy density non-aqueous lithium cells.

    New large offset far-infrared laser lines from CD3OH (1987)
    Springer
    Applied physics 44 (1987), S. 111-117 
    Details
    ISSN: 1432-0649
    Keywords: 42.55
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The CD3OH molecule has been investigated for new far-infrared laser lines by optically pumping with a cw waveguide CO2 laser. The increased tunability (300 MHz) with respect to a conventional CO2 laser permits to pump many new CD3OH lines. As a consequence 108 new laser lines have been discovered, ranging from 42.9 to 1155 μm in wavelength. On some lines the effect of an electric Stark field has been investigated demonstrating a laser frequency tuning. The total number of known FIR laser lines from CD3OH is increased to about 340 making this molecule the most prolific together with CH3OH.

    The Yarrowia lipolytica LEU2 gene (1987)

    Current genetics 11 (1987), S. 377-383

    ISSN: 1432-0983
    Keywords: Y. lipolytica ; LEU2 ; Yeast ; Leucine
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary A 2810 by DNA fragment containing the beta-isopropylmalate dehydrogenase gene of the dimorphic yeast Yarrowia lipolytica has been sequenced. The sequence contains an open reading frame of 405 codons, predicting a protein of 43,366 molecular weight. Protein sequence homology with the polypeptide encoded by the LEU2 gene of Saccharomyces cerevisiae is 64%, whereas DNA sequence homology is 61%. The 5′- and 3′-flanking regions of the Y. lipolytica LEU2 gene share only some general structural features common to genes of S. cereviside such as the presence and location of TATA boxes, CAAT boxes, CACACA repeats, the lack of G residues in the 5′-untranslated region and 3′-transcription terminators. Transcription of a 1.4 kb mRNA begins at a small cluster of sites approximately 40 base pairs before the initial ATG.

    Notes: Summary 4(5)-D-Arabinotetrahydroxybutylimidazoline-2-thione, THBIT, is proposed as a new reagent for the spectrophotometric determination of Pd(II). Pd(II) forms 1∶1, 1∶2 and 1∶4 complexes with THBIT. The system conforms to Beer's law up to 5μg/ml palladium concentration in aqueous medium (molar absorptivity, 1.99×104 l· mole−1·cm−1 at 338 nm). The most serious interference is from Hg(II), Os(VIII), Ru(IV), Cr(VI), V(V) and S2O3 2−. The method has been used successfully for the determination of palladium in catalysts and synthetic samples.

    Notes: Summary Derivatives of Imidazole as Spectrophotometric Analytical Reagents The synthesis, characteristics and metal-ion reactions of three imidazole derivatives, namely 4(5)-D-arabinotetrahydroxybutylimidazoline-2-thione (THBIT), and the oxime (IMALOX) and rhodanine (IMAR) of 4(5)-imidazolecarboxaldehyde, have been studied. IMALOX and IMAR exhibit three pK values in aqueous solution, but THBIT exhibits only one. All the reagents form stable complexes with only a small number of cations and some of them show promise as Spectrophotometric reagents.

    On kinematical minimum principles for rates and increments in plasticity (1986)

    Description / Table of Contents: Summary The optimization approach for elastoplastic analysis is discussed showing that some minimum principles related to numerical methods can be derived by means of duality and penalization procedures. Three minimum principles for velocity and plastic multiplier rate fields are presented in the framework of perfect plasticity. The first one is the classical Greenberg formulation. The second one, due to Capurso in rates and to Maier in finite terms, is developed here with different motivation, and modified by penalization of constraints so as to arrive at a third principle for rates. The counterparts of these optimization formulations in terms of discrete increments of displacements and plastic multipliers are discussed. The third one of these minimum principles for finite increments is recognized to be closely related to Maier's formulation of holonomic plasticity.
    Notes: Sommario Un approccio per ottimizzazione all'analisi elastoplastica è discusso mostrando che alcuni principi di minimo collegati a metodi numerici possono essere ricavati mediante dualità e tecniche di penalizzazione. Tra principi di minimo per campi di spostamenti incrementali e moltiplicatori plastici incrementali sono presentati nel contesto della plasticità perfetta. Il primo è la formulazione classica di Greenberg; il secondo, dovuto a Capurso in termini incrementali ed a Maier in termini finiti, è qui sviluppato con diversa motivazione e modificato con penalizzazione dei vincoli in modo da giungere ad un terzo principio incrementale. Si discutono le corrispondenti formulazioni di estremo in termini di incrementi finiti, di spostamenti e di moltiplicatori plastici. Si trova che il terzo di questi principi di minimo per incrementi finiti è strettamente connesso alla formulazione di Maier della plasticità olonoma.
