    An ultrastructural study of experimental high velocity penetrating head injury (1983)
    Springer
    Acta neuropathologica 59 (1983), S. 277-282 
    Details
    ISSN: 1432-0533
    Keywords: Trauma ; Missile head injury ; Astrocyte ; Blood brain barrier ; Ultrastructure

    Topics: Medicine
    Notes: Summary Experimental high velocity missile brain injury in the rhesus monkey produces widespread swelling of perivascular astrocytes within 30 min of injury. Possible mechanisms for this lesion include a direct effect of force, chemical mediation secondary to the extravasation of blood, alterations in the permeability of the blood brain barrier and ischaemia. The implications of this finding for the function of the blood brain barrier, for neurotransmission and for neuronal survival are discussed.

    Sensory-feedback system compatible with myoelectric control (1980)
    Springer
    Medical & biological engineering & computing 18 (1980), S. 65-69 
    Details
    ISSN: 1741-0444
    Keywords: Electrocutaneous stimulation ; Myoelectric control ; Prosthetics ; Sensory feedback
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract Progress in the development of a system to provide sensory feedback of the pinch force of an artificial hand is described. Design criteria relating to electrocutaneous stimulation and compatibility with myoelectric control are discussed. Details of a practical system, presently in use by two amputees prior to full-scale clinical evaluation, are presented.

    Error rate in five-state myoelectric control systems (1980)
    Springer
    Medical & biological engineering & computing 18 (1980), S. 287-290 
    Details
    ISSN: 1741-0444
    Keywords: Man-machine systems ; Multistate control ; Myoelectric control ; Prosthetics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract A myoelectric control system is one in which the operation of a device is controlled by the electric potential produced by voluntary contraction of a muscle. The utilisation of a single muscle site for the 3-state control of a myoelectric prosthesis has proven beneficial for certain amputees. It has been proposed that a single muscle site could be used for 5-state control, perhaps for an elbow and hand. This paper presents a preliminary study of the error probability for 5-state control.

    Rapid expansion of a cylindrical cavity in a rate-type soil (1984)
    New York, NY [u.a.] : Wiley-Blackwell
    International Journal for Numerical and Analytical Methods in Geomechanics 8 (1984), S. 125-140

    Keywords: Engineering ; Engineering General

    Topics: Architecture, Civil Engineering, Surveying , Geosciences
    Notes: An analytical solution for rapid (undrained) expansion of a long cylindrical cavity from initially zero radius is presented. A simple rate-type soil model possessing the salient features of the modified Cambridge critical state model is used. Application of the solution to determination of the stress field surrounding a pile immediately after driving is discussed.
