    Notes: Abstract Increased ambient pressure (excess hydrostatic pressure) was used to regulate cavitation in the aqueous media surrounding isolated red blood cells and aluminum foils used as targets in studies of the mechanisms of shock wave (SW) damage in shock wave lithotripsy (SWL). Foils or cells were placed in a cylindrical chamber (bronze-aluminum alloy) connected to a regulator and nitrogen source. The ends of the cylinder were capped with planar, plastic plates 12.7 mm thick. Tests performed with a PVDF membrane hydrophone showed that SW's passed through the plastic without significant loss of amplitude or change in waveform. Pitting of foils, a form of damage that can only be due to cavitation, was eliminated by very high (∼70 atm) added pressure. It took substantially greater added pressure to reduce damage to foils than has been reported to reduce damage to cells, suggesting differences in how cavitation is regulated in bulk fluid versus a solid surface. This report describes the design of the pressure chamber used in these studies and explains how SW exposures of isolated cells and foil targets were performed.

    Self-Efficacy as a Psychological Moderator of Chronic Fatigue Syndrome (1998)
    Springer

    Notes: Abstract Chronic fatigue syndrome (CFS) is characterized by debilitating fatigue and a variety of somatic symptoms. Few studies have examined psychological aspects of CFS. In the present study, self-efficacy is shown to be a significant predictor of CFS symptoms beyond the variance accounted for by demographic variables and distress. Further psychological CFS research is encouraged by (1)identifying dimensions that are salient in the experience and study of CFS, (2) providing preliminary psychometric data for measures of those dimensions, and (3)identifying psychological variables that serve as moderators of the experience of CFS.

    A fast solution method for three-dimensional many-particle problems of linear elasticity (1998)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 42 (1998), S. 1215-1229

    Notes: A boundary element method for solving three-dimensional linear elasticity problems that involve a large number of particles embedded in a binder is introduced. The proposed method relies on an iterative solution strategy in which matrix-vector multiplication is performed with the fast multipole method. As a result the method is capable of solving problems with N unknowns using only O(N) memory and O(N) operations. Results are given for problems with hundreds of particles in which N=O(105). © 1998 John Wiley & Sons, Ltd.
