    Taste Thresholds of Butter Volatiles in Deodorized Butteroil Medium (1969)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 34 (1969), S. 0

    Notes: —Taste thresholds of 31 volatile compounds found in butter were measured in deodorized butteroil and thresholds of seven volatiles were measured in fresh butter. Thresholds of mixtures of each of the major classes of volatile compounds (free fatty acids from C2 through C12, gamma-lactones from C7 through C11, even-numbered deltalactones from C8 through C14 and methyl ketones from C3 through C13 except C12 were determined as well as thresholds of single compounds of these classes. Butyric acid, diacetyl, delta-decalactone, 2-nonanone, gamma-undecalactone and n-hexanal, oftreported constituents of milk fat, had thresholds in butteroil of 0.66, 0.055, 1.4, 7.7, 0.95 and 0.19 ppm, respectively. The threshold of a mixture of free fatty acids from C2 through C12 was 0.55 ppm. Synergistic interactions among methyl ketones and free fatty acids were pronounced and interactions among aldehydes were weak, while interactions among lactones were not apparent.

    Cell Size, Macromolecule Composition, Nuclear Number, Oxygen Consumption and Cyst Formation During Two Growth Phases in Unagitated Cultures of Acanthamoeba castellanii (1969)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 16 (1969), S. 0

    Topics: Biology
    Notes: SYNOPSIS. The size, composition and physiology of average cells have been studied in cultures of Acanthamoeba castellanii during the phases of logarithmic growth and population growth deceleration (PGD). Most of the features examined were relatively constant during log phase, but had significant changes during PGD. Average cell volume increased about 60% and total dry mass about 15–20% during the latter period. Total protein content remained constant thruout both growth phases, but cytochrome oxidase doubled during PGD. DNA, RNA and glycogen levels began to change during late log phase. DNA decreased about 50% and RNA increased about 75%. Glycogen decreased 50% during the RNA build-up and then increased to a plateau above the log phase level. A final decrease in glycogen followed an increase in the relative numbers of cysts in late PGD.It was found that PGD begins when O2 becomes limiting and evidence that the subsequent changes in macromolecule composition are related to encystation is discussed.

    Anionic graft polymerization of lithiated poly(2,6-dimethyl-1,4-phenylene ether) (1969)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A-1: Polymer Chemistry 7 (1969), S. 2537-2545

    Topics: Chemistry and Pharmacology
    Notes: Lithiated poly(2,6-dimethyl-1,4-phenylene ether) has been used as an initiator for the graft polymerization of isoprene, methyl methacrylate, hexamethylcyclotrisiloxane, and phenyl isocyanate with the use of toluene and tetrahydrofuran as solvents. The products were examined by gel-permeation chromatography for evidence of homopolymerization and graft polymerization. The composition of the graft copolymers was determined by NMR, and for isoprene and hexamethylcyclotrisiloxane, termination by trialkylchlorosilanes enabled chain lengths to be determined by NMR. The use of toluene gave rise to some homopolymerization, but with tetrahydrofuran, only hexamethylcyclotrisiloxane gave homopolymer. In all cases, graft copolymers were formed. With isoprene and methyl methacrylate, soluble graft copolymers were formed in good yield. In the former case approximately 60% 3,4 and 40% 1,4 addition was found. In the latter case 1,1-diphenylethylene was used to reduce crosslinking, in its absence, methyl methacrylate gave only crosslinked gels in tetrahydrofuran. Hexamethylcyclotrisiloxane added only one molecule per lithium on the polymer, the remainder giving homopolymer. Phenyl isocyanate gave some soluble graft copolymer in toluene, but only crosslinked products were obtained when tetrahydrofuran was used as reaction solvent.

    Notes: The kinetics of the thermally and radiation initiated chain reaction between trichloroethylene and cyclopentane to produce 1,1-dichlorovinylcyclopentane and hydrogen chloride have been investigated in the temperature range 250-360°C at high pressure in the gas phase. The rate governing step in the chain is (k3 = 3.3 × 109 exp -(4800/RT) cc mole-1 sec -1). The rate of the unimolecular decomposition of trichloroethylene is 1.4 × 1014 exp -(61,200/RT) sec-1.

    Graft polymerization of styrene on lithiated poly(2,6-dimethyl-1,4-phenylene ether) (1969)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A-1: Polymer Chemistry 7 (1969), S. 1359-1369

    Topics: Chemistry and Pharmacology
    Notes: Styrene has been grafted onto poly(2,6-dimethyl-1,4-phenylene ether) (I) with the use of lithiated I as an initiator. In benzene solution, solvent metalation resulted in some polystyrene homopolymer. In tetrahydrofuran, however, only graft copolymer was formed. By forming a derivative with trimethylchlorosilane and examining by NMR, it was possible to establish the proportion of lithium scavenged by impurities, the amount of polymeric lithium which reacted with styrene, and the amount which did not. The chain length of the grafted polystyrene was also calculated. No crosslinking was found, except where a high ratio of lithium to styrene resulted in some unreacted ring-metalated polymer. In this case only, reaction with trimethylchlorosilane causes some crosslinking.

    Cucumber Green Mottle Mosaic Virus, its Effect on Yield and its Control in the Lea Valley, England (1969)
    Oxford, UK : Blackwell Publishing Ltd
    Plant pathology 18 (1969), S. 0

    Notes: Cucumber green mottle mosaic virus was very widespread in cucumber crops in the Lea Valley in 1964. Experiments on the effect of this virus on yield indicated that losses of approximately 15 per cent occurred with early infection. Later infection had little effect on yield.Dry heat treatment of infected cucumber seeds at 70°C for more than one day was sufficient to inactivate the virus and these results were also confirmed using virus-impregnated filter paper squares. Cucumber seeds were found to tolerate dry heat treatment at temperatures of 75°C and 80°C with little adverse effect but, at 80°C, germination was delayed and the cotyledon leaves were distorted.In a commercial trial, over 45,000 cucumber plants free from symptoms of the virus were raised from infected seeds which had previously been heat treated at 70°C for three days.
