    The mechanism of manganese electrodeposition (1974)
    Springer
    Journal of applied electrochemistry 4 (1974), S. 317-321 
    Details
    ISSN: 1572-8838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract The mechanism of manganese electrodeposition from a sulphate bath on to a stainless-steel substrate has been studied by using current efficiency data to resolve the totali-E curves. A simple, two-step electron transfer mechanism: $${\text{Mn}}^{{\text{ + + }}} + {\text{e}}\xrightarrow{{{\text{r}}{\text{.d}}{\text{.s}}}}{\text{Mn}}^{\text{ + }} $$ $${\text{Mn}}^{\text{ + }} + {\text{e}} \to {\text{Mn}}$$ is proposed to explain the following experimentally obtained parameters: cathodic and anodic transfer coefficients, reaction order and stoichiometric number. The mechanism also explains the effect of pH oni o,Mn and on the corrosion currents.

    Water involvement in diapause and the resumption of morphogenesis of the southwestern corn borer, Diatraea grandiosella (1973)
    Springer
    Entomologia experimentalis et applicata 16 (1973), S. 445-454

    Description / Table of Contents: Zusammenfassung Es wurde der Einfluss von Wasser auf Diapause und Wiederaufnahme der Morphogenesis bei Diatraea grandiosella untersucht. Reife Diapauselarven wurden aus Laborzuchten erhalten oder im Freiland in Südost-Missouri gesammelt. Sie wurden trocken gehalten oder hatten Zugang zu Wasser und zwar in verschiedenen Umgebungsbedingungen, bei denen bekanntermassen die Diapauseentwicklung mit verschiedener Geschwindigkeit erfolgt. Die Ergebnisse zeigten, dass die Diapauseentwicklung rascher ablief bei Larven, die trocken gehalten wurden als bei solchen mit dauerndem Kontaktwasser. Die Larven brauchen demnach keine exogene Wasserquelle zur vollständigen Diapauseentwicklung. Zwar begünstigt die Verfügbarkeit von Wasser nach der Diapause das Einsetzen der Verpuppungsphase; dennoch brauchten diejenigen Larven, deren Gewebswassergehalt bei über ca. 55% lag, überhaupt kein Kontaktwasser, um diese Phase, d.h. die Verpuppung, abzuschliessen. Der Wasserverlust von Diapauselarven bei trockenen und nassen Bedingungen wurde bestimmt und ebenso die aufgenommene Wassermenge nach Trockenperioden. Die physiologische Bedeutung der Ergebnisse in Beziehung zu anderen, ähnlichen Daten wird diskutiert.
    Notes: Abstract The effect of water on diapause and the resumption of morphogenesis of the southwestern corn borer was examined. Diapause larvae were held under dry conditions or with access to water in various environmental regimes known to permit different rates of diapause development. Results showed that diapause development occurred at a higher rate in larvae held dry than in those continuously supplied with contact water. Larvae did not, therefore, require an exogenous water source to complete diapause development. Although the availability of water promoted the post-diapause pupal moulting cycle of larvae which had completed diapause development, those which maintained a tissue water content 〉 ca. 55% did not require contact water to complete this cycle. The loss of water in diapause larvae held under dry conditions or with access to water along with the quantity imbibed following various periods of dehydration was estimated. The physiological significance of the results in relation to other similar data is discussed.

    Warping stresses in circular concrete slabs on hetényi foundation (1972)

    Description / Table of Contents: Übersicht Es werden dimensionslose Beiwerte für Verschiebung, Moment und Druck an kreisförmigen Betonplatten auf einem Hetényi-Grund abgeschätzt. Dabei wird angenommen, daß die Plattentemperatur mit der Plattentiefe entweder linear ansteigt oder linear abfällt. Die Ergebnisse werden mit denen von Leonards und Harr, sowie mit den an Streifenplatten auf Hetényi-Grund erhaltenen verglichen. Es zeigt sich, daß die Beanspruchung in der Plattenmitte im allgemeinen größer ist bei Lagerung auf einem Winkler-Grund, verglichen mit einem Hetényi-Grund.
    Notes: Summary Non-dimensional deflection, moment and pressure coefficients have been evaluated for circular concrete slabs on Hetényi foundation. The slab is subjected to temperature which either increases or decreases linearly with depth of slab. The results are compared with the results of Leonards and Harr, to study the effect of continuity. The results are also compared with the results for strip slabs on Hetényi foundation. The results indicate that stresses at the centre of slabs are, in general, higher for slabs on Winkler foundation when compared to those of the slabs on Hetényi foundation.
