    Loss of Stages after Continuous Passage of Toxoplasma gondii and Besnoitia jellisoni (1976)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 23 (1976), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Toxoplasma gondii, passed from mouse to mouse in the tachyzoite stage for 30–35 generations, developed cysts, which, when fed to cats, failed to produce oocysts. Besnoitia jellisoni, passed similarly for 20 generations, lost the capacity to form cysts. These phenomena are explained by a loss of genomes or gene products during the rapid passage selecting for tachyzoites.

    The absorption of water into a porous solid consisting of two dissimilar layers (1997)
    Oxford, UK : Blackwell Publishing Ltd
    European journal of soil science 48 (1997), S. 0

    Notes: Analytical modelling of the movement of water through porous solids consisting of more than one homogeneous layer is a problem in soil science and in construction engineering. In this paper equations based on the Green and Ampt model describe the absorption of water into a two-layer composite bar for the cases of absorption through a material of large sorptivity into one of smaller sorptivity and vice versa. These predictions are compared with experimental results. There is broad agreement between theory and experiment at all times. We conclude that the absorption of water into a two-layer composite is ultimately controlled by the second material in the absorbing sequence irrespective of whether this material has the larger or the smaller sorptivity.

    Little Hope for Markets in the USSR (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Economic affairs 3 (1983), S. 0 
    Details
    ISSN: 1468-0270
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Economics
    Notes: In the last JEA Arthur Seldon argued that increasing corruption in the USSR signalled the irrepressible emergence of markets. Ole-Jacob Hoff disagrees: since neither the people of Russian nor her rulers are acquainted with any framework for capitalist exchange, they are more likely to opt for the devil they know.

    Food Volatiles: Gas Chromatographic Determination of Partition Coefficients in Water-Lipid Systems (1968)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 33 (1968), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: SUMMARY– The distribution of volatile solutes between two immiscible solvents can be determined by a study of the vapor pressures in the corresponding single solvent systems, since the partition coefficient is related to the Henry's constants: Kp= k2k12. Application of this principle makes possible the gas chromatographic determination of partition coefficients involving nonvolatile solvents. The method was applied to a solvent pair consisting of paraffin oil and aqueous sodium sulfate. An approximate semilogarithmic relationship exists between the partition coefficient and number of carbon atoms within each homologous series of aldehydes, ketones, alcohols and esters. Saturation with sodium sulfate increased the partial pressure of volatiles from 12 to 20 times. The partial heat of vaporization of volatiles in paraffin oil decreased with increasing temperature and was appreciably smaller than that of the pure compound at its boiling point. These observations may be utilized in quantifying food volatiles in operations involving extraction and gas stripping prior to analysis.

    Tomato Volatiles: Effect of Variety, Processing and Storage Time (1969)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 34 (1969), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: SUMMARY— Volatile components of three varieties of tomatoes processed in plain tin and enamel can linings at 0, 1, 4 and 8 months storage time were determined. A recently developed extraction method was used for separation and collection of volatiles free of moisture. This method allowed the study of small quantities of materials in a reasonable time. Multiple sampling of the vapor aliquots permitted qualitative and quantitative analysis.The greatest qualitative and quantitative differences in volatile composition were noted between the raw and heat processed samples. Methyl sulfide which was absent in the fresh fruit was formed during the heat process. The concentrations of acetaldehyde, acetone, methanol, and hexanal were significantly altered by processing. Differences between varieties were due to varying quantities of individual constituents but quantitative differences between can lining were less apparent.

    Time-Temperature Effects on the Bacteriological Quality of Stored Shellfish. (1967)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 32 (1967), S. 0

    Notes: -The effects of storage at 10, 20, and 27.5°C on the bacteriological quality and pH of living oyster and clam shellstock was studied. Bacteriological indices used were coliform MPN, fecal coliform MPN, and 35°C plate counts. Twelve lots of each oyster species and eleven lots of each clam species were studied. No distinct seasonal patterns in bacteriological changes were found. The 35°C plate count showed the most consistent response, the rate of increase being more rapid at the higher temperatures. Coliform MPN changes were less consistent in their response to temperature, and patterns of change were observed in different species. The fecal coliform MPN showed the greatest stability, with increases occurring only at 27.5°C. The pH changed little at any of the three temperatures.

    Notes: —The effect of storage in crushed ice and at 3 and 10°C on the bacteriological quality of shucked Pacific osyters and Olympia osyters was determined. The indices used were the 35°C plate count, coliform MPN, fecal coliform MPN, and pH. Fifteen lots of Pacific oysters and 12 lots of Olympia oysters, collected at various seasons, were examined. The 35°C plate count showed the best correlation with time and temperature OF storage. Fecal coliform MPN's showed the greatest stability under all storage conditions. Coliform MPN's increased at all three temperatures, but the patterns of change were less uniform than those of the 35°C plate count. The pH changes generally showed poor correlation with bacteriological changes.

    Characteristics of Rice Cultivars with Implications for Crawfish Double Cropping (1988)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the World Aquaculture Society 19 (1988), S. 0 
    Details
    ISSN: 1749-7345
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Twenty-five domestic rice (Oryza sativa L.) cultivars were evaluated in a simulated rice/crawfish double cropping system in southwest Louisiana during 1983 and 1984. Wide variation was observed among cultivars in parameters believed to be important for maximizing productivity in such a system. Mean maturity ranged from 99 (Labelle) to 118 days (Starbonnet), while height ranged from 76 (Bellemont) to 130 cm (Della, Nato). Significant differences in grain yield response were observed, with yields ranging from 4,101 (Bluebelle) to 6,665 kg/hectare (Newbonnet). Straw dry matter production varied greatly, from 3,831 (Bellemont) to 9,170 kg/hectare (Della), and was positively correlated with plant height (r = 0.64; P = 0.0001). Ratoon biomass production was negatively correlated with both grain yield (r = -0.39; P = 0.0001) and maturity group (r = -0.69; P = 0.0001). Plant senescence at grain maturity also varied greatly and appears to be a factor in post-harvest ratoon capability. Early or very early maturing cultivars with both proven grain production and good ratooning capability appear best suited. Cultivar selection should be based upon individual farm situations and currently employed agronomic practices.
