    Abdominal expansion using a polytetrafluoroethylene prosthesis in the treatment of Pepper syndrome (2000)
    Springer
    Pediatric surgery international 16 (2000), S. 219-221

    Notes: Abstract The authors report three cases of stage IV-S neuroblastoma in infants aged 4, 6, and 8 weeks, who despite chemo- and radiotherapy required surgical intervention to urgently relieve major thoracoabdominal compression secondary to massive hepatomegaly. The results were successful, with abdominal expansion being achieved by the introduction of a polytetrafluoroethylene prosthesis, which was removed during the 2nd, 3rd and 7th postoperative month, respectively, after tumor regression. Two children were in complete remission 32 and 38 months later, the 3rd died after 16 months of tumor progression.

    A system of insect neurons sensitive to horizontal and vertical image motion connects the medulla and midbrain (1991)
    Springer
    Journal of comparative physiology 169 (1991), S. 355-367 
    Details
    ISSN: 1432-1351
    Keywords: Motion-sensitive neurons ; Direction-selective neurons ; Insect medulla ; Contrast frequency ; Motion detection

    Topics: Biology , Medicine
    Notes: Summary The response properties and gross morphologies of neurons that connect the medulla and midbrain in the butterfly Papilio aegeus are described. The neurons presented give direction-selective responses, i.e. they are excited by motion in the preferred direction and the background activity of the cells is inhibited by motion in the opposite, null, direction. The neurons are either maximally sensitive to horizontal motion or to slightly off-axis vertical upward or vertical downward motion, when tested in the frontal visual field. The responses of the cells are dependent on the contrast frequency of the stimulus with peak values at 5–10 Hz. The receptive fields of the medulla neurons are large and are most sensitive in the frontal visual field. Examination of the local and global properties of the receptive fields of the medulla neurons indicates that (1) they are fed by local elementary motion-detectors consistent with the correlation model and (2) there is a non-linear spatial integration mechanism in operation.

    Physical modelling fire performance of wall-covering materials (1993)
    New York, NY [u.a.] : Wiley-Blackwell
    Fire and Materials 17 (1993), S. 293-303

    Notes: A small-scale enclosure was constructed for characterizing the contribution of interior finish wall-lining materials to fire growth in compartments. The enclosure was based upon refinements to a design devised by scientists at the National Institute for Standards and Technology for quarter-scale modelling of room fire tests on interior-finish materials. A large volume of evidence is presented demonstrating how this small-scale enclosure could provide the information about surface flammability, heat release, smoke generation and contribution to fire growth that is required for a reasonable assessment of the fire performance of interior wall-finish materials.

    Notes: The mass spectra of 3,8-dichloro-11H-dibenzo[c,f] [1,2]diazepine, the corresponding diazepin-11-01 and diazepin-11-one and their dihydro and N-oxide derivatives have been recorded. The most important fragmentation of the molecular ions of all diazepines studied was an initial loss of m/e 28, with further fragmentation depending on the 11-substituent. No general pathway was observed for the corresponding N-oxides and dihydro compounds.
