    Notes: Infection by Sclerotinia narcissicola Greg, was observed in narcissus bulbs during autumn, in leaf initials colonized by bulb scale mites (Steneotarsonemus laticeps (Halb.)), and on lesions of varying extent on the corresponding tissue after emergence.Presence or absence of smoulder sclerotia on outer scales of bulbs was not related to the incidence of infection of shoots.There was no evidence that smoulder was reduced by treatment for control of bulb mites (Rhizoglyphus echinopus (Fum. & Rob.)).

    Rotavirus infection in lambs: Pathogenesis and pathology (1977)
    Springer
    Archives of virology 55 (1977), S. 263-274 
    Details
    ISSN: 1432-8798

    Topics: Medicine
    Notes: Summary Experimental lamb rotavirus infections were studied by immunofluorescence, histopathology and electron microscopy of tissues from infected gnotobiotic lambs killed at intervals from the incubation period to recovery. The rotavirus was demonstrated by immunofluorescence only in epithelial cells of villi in the small and large intestine, and virus antigen was most abundant during the incubation period. An increased enterocyte turnover rate was suggested by the rapid movement of virus-infected cells to the villus tip, and this increase may be one of the basic pathogenic mechanisms of rotavirus infection. Principal histopathological changes were shortening of villi and sloughing of epithelial cells. These were greatest in the middle and posterior small intestine at the onset of diarrhoea, but regeneration occurred within a few hours. Virus morphology in tissues was similar to that reported in other species, and virus presence correlated well with histopathological change.

    Detection and transmission of 30 nm virus particles (astroviruses) in faeces of lambs with diarrhoea (1977)
    Springer

    Notes: Summary An outbreak of diarrhoea in lambs was investigated, and electron microscopic examination revealed small round virus-like particles in the faeces from eight of seventeen lambs. A bacteria-free filtrate of faeces from one lamb was given orally to a gnotobiotic lamb, which subsequently excreted virus in faeces. Intestinal contents were collected from this lamb and a filtrate given orally to two further gnotobiotic lambs, which subsequently developed diarrhoea and excreted virus in faeces. The mean diameter of the virus particles was 29.7 nm, and 12 per cent of them showed their surface structure arranged in the form of a six-pointed or five-pointed star. They were similar to those particles previously observed in human infant faeces which were referred to as “astroviruses”. The passage through gnotobiotic lambs with development of diarrhoea showed that these particles were animal viruses which were probably pathogenic for lambs.

    Pathogenesis of diarrhoea caused by astrovirus infections in lambs (1979)
    Springer
    Archives of virology 60 (1979), S. 217-226 
    Details
    ISSN: 1432-8798

    Topics: Medicine
    Notes: Summary Experimental infection of 2-day-old gnotobiotic lambs with lamb astrovirus produced mild diarrhoea after an incubation period of about 48 hours. No other clinical symptoms developed. Infection was studied by immunofluorescent and histological examination of tissues from the lambs. Astroviruses infected only mature villus epithelial cells and subepithelial macrophages in the small intestine, where they produced partial villus atrophy. Infected enterocytes were replaced with cuboidal cells from the crypts, and the lesion gradually healed by 5 days after infection. No serological relationship was detected by immunofluorescence between lamb astrovirus antigen in gut sections and antisera to either calf or human astrovirus.

    Aggregations of synaptic vesicles on the exposed inner membrane of presynaptic mitochondria in brain (1979)
    Springer
    Journal of neurocytology 8 (1979), S. 675-685

    Notes: Summary Fragments of rat cerebral cortex have been incubated under various conditions. When divalent cations are present, patches of the external membrane of some mitochondria are disassembled leaving the inner mitochondrial membrane exposed to the cytoplasm. Sometimes the entire external membrane is missing. In presynaptic bulbs the synaptic vesicles are attracted and adhere to the exposed outer face of the inner mitochondrial membrane. The mode of attraction and adhesion of the vesicles is discussed. Possibly this could serve as a model for further investigation of the attraction of vesicles to the active zone of the presynaptic membrane.

    Scattering of a surface wave by a submerged sphere (1978)
    Springer
    Journal of engineering mathematics 12 (1978), S. 15-41

    Notes: Summary The problem of the scattering of a surface wave in a nonviscous, incompressible fluid of infinite depth by a fully submerged, rigid, stationary sphere has been reduced to the solution of an infinite set of linear algebraic equations for the expansion coefficients in spherical harmonics of the velocity potential. These equations are easily solved numerically, so long as the sphere is not too close to the surface. The approach has been to formulate the problem as an integral equation, expand the Green's function, the velocity potential of the incident wave, and the total velocity potential in spherical harmonics, impose the boundary condition at the surface of the sphere, and carry out the integrations. The scattering cross section has been evaluated numerically and is shown to peak for values of the product of radius and wave number somewhat less than unity. Also, the Born approximation to the cross section is obtained in closed form.
