    Notes: SUMMARY— Organoleptic and chemical deterioration of freshwater whitefish muscle frozen at −10°C for periods up to 16 weeks was assessed. As frozen storage of muscle progressed, the toughness and rancidity of baked muscle increased. The solubility of the myofibrillar protein fraction, “actomyosin,” dropped from about 72 to 22% over the 16 week storage period of whitefish muscle. No change in the solubility of sarcoplasmic protein in frozen stored muscle was observed. However, with polyacrylamide disc electrophoresis, two new sarcoplasmic protein bands were detected after 16 weeks of storage. With storage of frozen muscle, water-binding capacity diminished. Although the total lipid and cholesterol contents of muscle remained constant throughout frozen storage, the phospholipid content decreased as the free fatty acid content increased. Oxidative deterioration of lipid in frozen muscle was estimated.

    Chemical Deterioration of Frozen Bovine Muscle at −4° C (1968)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 33 (1968), S. 0

    Notes: SUMMARY— During an 8-week storage period of bovine muscle at −4°C, the total extractable protein content dropped from 91 to 51%. This decline, accompanied by a decrease in water-binding capacity of muscle, was primarily caused by the insolubilization of both sarcoplasmic proteins and actomyosin. The increase in the free fatty acid content from about 1.6 to 9.1% over the 8-week period may be attributed to phospholipid hydrolysis. The TBA number rose progressively throughout the entire storage period while the peroxide value increased to a maximum in 2 weeks of storage and then decreased to a constant value of 7.

    Electroplating of antimony and antimony-tin alloys (1987)

    Notes: Abstract The electroplating of antimony from KSb(OH)6 and antimony-tin alloys from mixtures of KSb(OH)6 and Na2Sn(OH)6 onto steel substrates has been investigated under variable plating conditions. The influence of added tartaric acid, current density and temperature on cathodic potentials, cathodic current efficiencies, appearance of the deposits and chemical composition of the alloys has been studied. X-ray diffraction analysis has showed that amorphous or hexagonal antimony deposits are produced from solutions free from or containing tartaric acid. The alloy deposit (56% antimony) was produced in rhombohedral crystal structure. Fine-grained, highly adherent and dark-greyish deposits of antimony and antimony-tin alloys were plated in most cases.

    Description / Table of Contents: Zusammenfassung Auf zwei verschiedene Arten hergestellte Molybdäntrioxidkatalysatoren wurden für selektive Oxidationen untersucht. Die Ergebnisse der Dampfphasenoxidation von Methanol werden auf Basis der sauren Eigenschaften, der oxidierenden Funktionen und der kristallographischen Struktur der Katalysatoren diskutiert. Es wurde festgestellt, daß die sauren Eigenschaften zur Erklärung der entscheidenden Wirksamkeit der Katalysatoren nicht alleine verantwortlich sind. Elektrische Leitfähigkeitsmessungen zeigten, daß molekularer Sauerstoff im zugeleiteten Gas zur Erhaltung der katalytischen Aktivität notwendig ist. Die Unterschiede in der Katalysatoraktivität und der Selektivität sind aus der Struktur der Katalysatoren zu erklären. Es wird ein adäquater Redox-Mechanismus diskutiert.
    Notes: Summary As catalysts for selective oxidation, molybdenum trioxide catalysts—prepared by two different methods—have been investigated. The results of vapor-phase oxidation of methanol are discussed on the basis of the acidic property, oxidizing functions, and the crystallographic structure of the catalysts. It was found that the acidic property is not the sole factor deciding the catalytic activity. Electrical conductivity measurements proved that molecular oxygen in the gas feed is necessary for maintaining the catalysts active. The difference in the catalytic activity and selectivity were reasonably interpreted in view of the structure sensitivity of those catalysts. A redox mechanism is also discussed in this paper.

    Description / Table of Contents: Zusammenfassung Es wurden die sauren Eigenschaften und die katalytische Aktivität von 12-Molybdänphosphaten (M x/n n+ H3-x PMo12O40;M = Cu2+, Bi3+, Cr3+ andX=1−3) untersucht. Die Ergebnisse werden bezüglich der Partialladung am Sauerstoffatom diskutiert, wobei gezeigt wird, daß die Sauerstoff—Wasserstoff-Bindung mit negativerem Sauerstoff schwächer wird, während die katalytische Dampfphasen-Dehydrierungsaktivität an 2-Propanol mit der Reaktionszone der pseudoflüssigen Struktur der Heteropolyverbindungen in Zusammenhang gebracht werden kann. Die Redox-Eigenschaften der Katalysatoren beim prozentuellen Umsatz der Reaktion von 2-Propanol sind direkt mit der fraktionellen Ladung am Molybdänatom zu korrelieren.
    Notes: Abstract The acidic properties and the catalytic activity of 12-molybdophosphates (M x/n n+ H3-x PMo12O40;M = Cu2+, Bi3+, Cr3+ andX=1−3) have been studied. The results are discussed as the effect of these catalyst components on the partial charge on oxygen atom which is in a relation with the acidity. It is shown that the oxygen-hydrogen bond is weakened as the value of partial charge on oxygen (− δ0) becomes more negative, while the vapor-phase dehydration activity of 2-propanol was explained on the basis of the reacting zone wideness taking into account the pseudo liquid phase nature of the heteropoly compounds. A correlation of the percentage conversion of 2-propanol with the fractional charge on the molybdenum atom was successful to interpret the effect of the redox properties of these catalysts on their catalytic activity.

    Notes: Summary The sensitivity of TE98 (carryingw +R andrst +) to X-rays does not differ significantly from the mutability ofcurled andkarmoisin loci. In addition no spontaneous mutants of TE98 were recovered, indicating its extreme stability. On the effect of EMS nowhite mutants were found supporting the view that thew + gene of TE98 is duplicated.
