    Notes: Summary At birth, hepatic ‘active’ and ‘dichloracetate-activated’ pyruvate dehydrogenase complex activities in the newborn of normal, mildly diabetic, and severely diabetic rats were similar. The ‘active’ and ‘dichloracetate-activated’ pyruvate dehydrogenase complex activities increased significantly during the first 2 and 6 postnatal h, respectively in the three groups of neonates (p〈0.05). The greatest increase in both ‘active’ and ‘dichloroacetate-activated’ pyruvate dehydrogenase complex activity was observed in the neonates of mildly diabetic rats. Administration of glucose or insulin at birth to the newborn of normal rats caused a significant increase in the percentage of ‘active’ pyruvate dehydrogenase complex activity within 1 h (p〈0.01). Similar treatment caused no significant increases in the newborn of severely diabetic rats. The transient increases in ‘active’ pyruvate dehydrogenase complex activity in the neonates of normal and diabetic rats were consistent with rapid disappearance of blood lactate during the first hours of postnatal life.

    Mottling phenomena and quality of grains of different genotypes of Durum wheat grown under limited irrigation conditions (1985)

    ISSN: 1573-5036
    Keywords: Biochemical composition ; Durum wheat ; Genotypes ; Irrigation ; Mottling of grain

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Field experiment was conducted to show the effect of one irrigation of 10 cm water applied to durum wheat (Triticum durum) at crown root initiation stage, active tillering stage, anthesis stage and compared them with non irrigated plot using A-206, A-28, A-1-8-8-42-1, G.W.-1 and A-23-10 genotypes under the conditions of salt affected areas having shallow saline aquifer, on quality, yield and mottling phenomena in wheat grain. Application of irrigation significantly increased the yield and decreased the per cent mottled grain and the maximum achievement was obtained when water was applied during the stage of anthesis. Non mottled grain contained higher protein than mottled grain and there were no considerable differences in other biochemical constituents. Genotype G.W.-1 stands first in its yield performance and low mottled grain.

    A theory for vortex shedding from the keels of marine vehicles (1985)
    Springer
    Journal of engineering mathematics 19 (1985), S. 265-295 
    Details
    ISSN: 1573-2703
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics , Technology
    Notes: Summary This paper presents a discrete vortex-shedding method for predicting the damping forces experienced by a floating marine vehicle responding at and around roll resonance. The method utilizes a Schwartz-Christoffel transformation, the temporal flow development being calculated to yield vortex positions, pressures and overall forces on the vessel hull. The effect of the velocity term in Bernoulli's equation on hull forces is calculated by integrating pressure and confirmed using the Blasius formula. A functional form of the vortex-induced moment amplitude is deduced from the theory and applied to a frequency-domain equation of roll motion for the vessel. Comparison of theory with test data indicates that the vortex-shedding theory does predict the effects of this phenomenon on the roll motions of a specific hull shape. An extensive review of previous work in this area is also presented.

    Description / Table of Contents: Poly-8-hydroxychinolin-furfural (8HQ-Fu) wurde durch Kondensation von 8-Hydroxychinolin mit Furfural in Gegenwart von wäßrigem K2CO3 und NaOH als Katalysatoren hergestellt. Dabei wurden die beiden Reaktanden in äquimolaren Verhältnissen eingesetzt. Die Polymerproben wurden durch Elementaranalysen, IR-Spektren und thermogravimetrische Analysen charakterisiert.

Grenzviskositäten aller Polymerproben wurden in DMF gemessen.Polymere Metallchelate von Cu2+, Fe3+, Co2+, Zn2+, Mn2+, Ni2+ mit 8HQ-Fu wurden hergestellt und charakterisiert.
    Notes: Poly(8-hydroxyquinoline-furfural) (8HQ-Fu) was prepared by condensing 8-hydroxyquinoline with furfural in the presence of aqueous K2CO3 and NaOH as catalysts using equimolar proportions of the two reactants. The polymer samples were characterized by elemental analysis, IR spectra, and thermogravimetric analysis. The number average molecular weight (Mn) was determined both by vapour pressure osmometry and by non-aqueous titration. Intrinsic viscosities of all the polymer samples were measured in DMF.Polymeric metal chelates of Cu2+, Fe3+, Co2+, Zn2+, Mn2+, Ni2+ with the 8HQ-Fu polymer were prepared and characterized.

    Description / Table of Contents: Mit Polyacrylnitril gepfropfte Stärke wurde aus Stärkegranulat von herkömmlicher Hirse (Penicum Miliaceum, L) hergestellt, und seine Verarbeitungsmöglichkeiten unter Verwendung des Brabender Plasticorders wurden untersucht. Glycerin als bekannter Weichmacher für Stärke ist als Weichmacher für dieses Polymere nicht geeignet. Eine Mischung von 1:1 Stärke : Stärkepfropfpolyacrylnitril und 25% Glycerin kann verarbeitet und zu einem Film extrudiert werden. Die Festigkeit des Films war geringer als die der reinen Stärke. Der Film, der aus dem Pfropfcopolymeren und mit Polymethylmethacrylat gepfropfter Stärke hergestellt war, hatte eine hohe Zugfestigkeit. Über die Daten der Fließaktivierungsenergie, die mit einem Torsionsrheometer erhalten wurden, wird ebenfalls berichtet.
    Notes: Starch-graft-polyacrylonitrile (S-g-PAN) has been prepared from granular starch of common millet (Penicum miliaceum, L) and its processibility has been examined using the Brabender Plasticorder. Glycerine, a known plasticizer for starch does not work as plasticizer for S-g-PAN. A mixture of 1 : 1 starch : S-g-PAN and 25% glycerine can be processed and a film can be extruded. The strength of the film was less than that of pure starch. The film prepared from the mixed graft copolymer of S-g-PAN and S-g-PMA had high tensile strength. The data on flow activation energy obtained from the torque-rheometer are also reported.

    Description / Table of Contents: Die vorliegenden Untersuchungen sollen einen Beitrag zur Strukturaufklärung von amorphen Polymeren mit starren Polymerketten darstellen. Zu diesem Zweck wurden Celluloseacetate (CA) mit verschiedenen Substitutionsgraden (DS) hergestellt. Die Proben wurden durch IR-Spektroskopie, Differential-Scanning-Calorimetry (DSC) und dynamisch-mechanische Analyse (DMA) charakterisiert. Rasterelektronenmikroskopische Aufnahmen von gefriergebrochenen Oberflächen dieser Polymeren zeigten, daß außer lamellaren Strukturen auch kugelige Strukturen beobachtbar waren.
    Notes: In the present investigation an attempt has been made to throw light on the structure of stiff chain amorphous polymers. For this purpose cellulose acetates (CA) having different degrees of substitution (DS) were prepared. The samples were characterised by IR-spectroscopy, Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Analysis (DMA). Scanning electron micrographs of the cryogenically fractured surfaces of these polymers showed that along with lamellar structures, nodular structures were also observable.

    An evaluation of eight discretization schemes for two-dimensional convection-diffusion equations (1986)

    Notes: A comparative study of eight discretization schemes for the equations describing convection-diffusion transport phenomena is presented. The (differencing) schemes considered are the conventional central, upwind and hybrid difference schemes,1,2 together with the quadratic upstream,3,4 quadratic upstream extended4 and quadratic upstream extended revised difference4 schemes. Also tested are the so called locally exact difference scheme5 and the power difference scheme.6 In multi-dimensional problems errors arise from ‘false diffusion’ and function approximations. It is asserted that false diffusion is essentially a multi-dimensional source of error. Hence errors associated with false diffusion may be investigated only via two- and three-dimensional problems. The above schemes have been tested for both one- and two-dimensional flows with sources, to distinguish between ‘discretization’ errors and ‘false diffusion’ errors.7 The one-dimensional study is reported in Reference 7. For 2D flows, the quadratic upstream difference schemes are shown to be superior in accuracy to the others at all Peclet numbers, for the test cases considered. The stability of the schemes and their CPU time requirements are also discussed.
