    Notes: [Auszug] The polymer is readily soluble in perfluoromethyl-c^/cfohexane, and the mean molecular weight is much greater than 7,000. Support for the constitution of the polymer is given by the fact that when heated in vacuo at 400 in absence of air, fche polymer yields equimolar amounts of ...

    The development of an attenuated foot-and-mouth disease virus vaccine by modification and cloning in tissue cultures of BHK 21 cells (1969)

    Notes: Summary An attenuated strain of foot-and-mouth disease virus, type SAT1, has been developed by serial passage in tissue cultures of BHK 21 cells and cloning by plaque isolation. Clones of attenuated virus were obtained after 48 passages in culture. Uncloned virus was still pathogenic at the 90th passage but was attenuated by the 150th passage. Tests of the immunising properties of a clone prepared after the 82nd passage of the strain in over 100 cattle and 36 sheep showed that approximately 80% of the cattle given a dose of 108.0MID50 and all of the sheep given 107.5MID50 were protected against challenge. The vaccine strain was not transmitted to in-contact control cattle. Advantages of this method of attenuation are: 1. Early separation of attenuated from pathogenic clones of virus makes possible the rapid development of an attenuated strain vaccine. 2. Screening large numbers of virus clones by inoculation of cattle tongues simplifies the selection of those which have the first necessary attribute of any live vaccine, viz. safety for the species to be immunised. 3. Attenuation of virus in BHK 21 cells results in strains capable of rapid growth to high titres. The same tissue culture systems provides a convenient method for the large scale manufacture of vaccine.

    Dune stabilization in Queensland, Australia, using vegetation and mulches (1976)
    Springer
    International journal of biometeorology 20 (1976), S. 1-8 
    Details

    Notes: Abstract Coastal dunes in Queensland are usually vegetated because climatic conditions favour the growth of dune plants. Occasionally extreme climatic conditions, e.g. gales, droughts, wave erosion, or man's activities, e.g. grazing, access, development, destroy dunal vegetation and onshore winds move sand inland, accelerating coastal erosion. Replacement of vegetation is indicated in severe cases. The paper described trials done on Stradbroke Island into methods of re-establishing vegetation on dunes using different surface mulch treatments, including organic materials (straw and brush), and spray-on emulsions (bitumen, P.V.A. mineral oil-synthetic latex). All treatments (except the oil-latex emulsion) allowed ready establishment of vegetation. The bitumen and P.V.A. treatments could be used to replace the traditional organic mulches, subject to certain conditions. Data is presented on climate, soil temperatures, resistance to wind erosion plant ground covers and densities.

    The use of interferon production as a marker in the development of a modified strain of foot-and-mouth disease virus (1968)
    Springer

    Notes: Summary A strain of foot-and-mouth disease was modified by passage in BHK21 cells and selection of clones. Development of innocuity for cattle of the passaged virus and of clones was correlated with increased interferon production and decreased cytopathogenicity for calf thyroid tissue culture infected with 104 PFU of virus. Immunogenicity of virus was correlated with the occurrence of viraemia in cattle and to a limited extent with ability to multiply in bovine tongue epithelial cultures. Although avirulent clones were obtained, the immune response of cattle was inadequate to confer protection.
