    Ideal technique and sites for intramuscular injection in infants and children (1989)
    Springer
    Pediatric surgery international 4 (1989), S. 140-142 
    Details
    ISSN: 1437-9813
    Keywords: Intramuscular injection ; Infants and children

    Topics: Medicine
    Notes: Abstract Complications following intramuscular (IM) injections in infants and children are quite frequent. Various studies have revealed that in most of the cases drugs were either injected into the subcutaneous tissue plane or into the muscle, where a disparity between the volume of injected material and the volume of muscle mass where it was injected was obvious. The consequences were either fat-necrotic abscess or muscle fibrosis leading to deformity of the nearby joint. On the basis of our studies and other observations, the ideal technique of IM injection and the best sites for injection in infants and children are suggested in order to prevent complications.

    Stabilization of a class of hybrid systems arising in flexible spacecraft (1986)
    Springer
    Journal of optimization theory and applications 50 (1986), S. 83-108 
    Details
    ISSN: 1573-2878
    Keywords: Flexible spacecraft ; dynamic modelling ; coupled systems of ordinary and partial differential equations ; system stabilization ; Lyapunov's functionals ; feedback control
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract We consider the problem of rigorous modelling of flexible spacecraft and their stabilization. It is shown that the dynamics of the flexible spacecraft can be described by a coupled system of ordinary differential equations and partial differential equations (hybrid system). Lyapunov's approach is used to prove the stabilizability of the system. Simple feedback controls are suggested for stabilization of flexible spacecraft.

    Hardness estimated from the indentation of a spherical body. Some implications for nanoindentation test results (1996)
    Springer
    Tribology letters 2 (1996), S. 381-391 
    Details
    ISSN: 1573-2711
    Keywords: nano-indentation ; surface roughness ; macroscopic modeling
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Spherical bodies made of copper were macro-indented by steel balls. The estimated hardness was found to increase with the specimen curvature and vary with the location of contact on the spherical surface. The implications of these results on the nanoindentation test results, especially when the indented surface is rough or displacement measurement is faulty, is discussed.
