    A technique for modelling the performance of birefringent wave plates (1999)
    Springer
    Optical and quantum electronics 31 (1999), S. 645-653 
    Details
    ISSN: 1572-817X

    Thema: Elektrotechnik, Elektronik, Nachrichtentechnik , Physik
    Notizen: Abstract By considering the phase delay introduced by a birefringent wave plate to each frequency component of a finite bandwidth light source we establish the polarisation state of the transmitted light. Realisable designs of achromatic, zero-order and high-order quarter wave and half wave plates are analysed for use with a variety of light sources with different bandwidths.

    Spontaneous Chronic and Subacute Subdural Haematoma in Young Adults (2000)
    Springer
    Acta neurochirurgica 142 (2000), S. 1307-1310 
    Details
    ISSN: 0942-0940
    Schlagwort(e): Keywords: Spontaneous subdural haematoma; chronic subdural haematoma; subacute subdural haematoma; non-acute subdural haematoma.

    Notizen: Summary  Spontaneous subacute and chronic haematoma in young adults is rare. It has not been previously reported in this age group.  We present three cases of chronic and subacute subdural haematoma in young adults, in one of whom the diagnosis was certainly delayed.  All three patients underwent burrhole evacuation and made a full neurological recovery. A cause for the haematoma was never established. The literature on the subject, which is scanty, is reviewed and the condition is briefly discussed. The aetiology remains obscure.

    The toxicological properties of impurities in malathion (1978)
    Springer
    Archives of toxicology 42 (1978), S. 95-106 
    Details
    ISSN: 1432-0738
    Schlagwort(e): Malathion ; Isomalathion ; Trimethyl phosphorothioates ; Acetylcholinesterase ; Carboxylesterase ; Potentiation of toxicity

    Notizen: Abstract During a malaria eradication programme in Pakistan in 1976, out of 7,500 spraymen, 2,800 became poisoned and 5 died. The major determinant of this poisoning has been identified as isomalathion present as an impurity in the malathion. It seems almost certain that the isomalathion was produced during storage of the formulated malathion. The quantitative correlation found between isomalathion content and toxicity of many field samples of malathion has been confirmed by an examination of mixtures of pure compounds. Addition of known amounts of isomalathion to technical malathion indicates that other active substances are present. These impurities have been identified (trimethyl phosphorothioates) and have been shown to behave like isomalathion in potentiating the toxicity of malathion. Some preliminary work on their toxicological properties is reported. The mechanisms involved in the potentiation of the toxicity of malathion are discussed.

    Mid-infrared imaging of ultracompact H II regions (1994)
    Springer
    Experimental astronomy 3 (1994), S. 159-160 
    Details
    ISSN: 1572-9508
    Schlagwort(e): H II regions
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract We discuss preliminary results of an 11.7 μm imaging survey of ultracompact H II regions from the Wood and Churchwell radio survey. We find that that the morphologies of ionized gas and warm dust are often significantly different, indicating that an H II region classification scheme should be based on more than radio data.
