The Shifman-Vainshtein-Zakharov method of determining the eigenvalues and coupling strengths, from the operator product expansion, for the current correlation functions is studied in the nonrelativistic context, using the semiclassical expansion.
The relationship between the low-lying eigenvalues, and the leading corrections to the imaginary-time Green function is elucidated by comparing systems which have almost identical spectra. In the case of an anharmanic oscillator it is found that with the procedure stated in the paper, that inclusion of more terms to the asymptotic expansion does not show any simple trend towards convergence to the exact values. Generalization to higher partial waves is given. In particular for the P-level of the oscillator, the procedure gives poorer results than for the S-level, although the ratio of the two comes out much better.

Oscillator strengths for triplet-triplet transitions in fluid solution are reported. From these resuIts and from a comparison with previous work, experimental support is provided for the constancy of triplet-triplet oscillator strengths under various solvent and temperature conditions.
A method for determining the dissipation and coupling loss factors of a fully assembled machinery structure is presented in this paper. The method is based on the experimental measurements of the total loss factors and the energy ratios between the subsystems of the machine structure when fully asse
The dual multiple reciprocity method (MRM) has been employed by the authors' group [3] to solve the acoustic modes of a cavity with or without a thin partition. In this paper, we propose the singular-value decomposition technique to "lter our spurious eigenvalues and to determine the multiplicity of
## Abstract Verifying the duality of electric and magnetic fields using the nonstandard FDTD method is important for farβfield calculations using the equivalence principle and for the reduction of reflection from boundaries of different size lattices. In this paper, the duality of the fields using
Immobilized enzymes are widely used i n the clinical laboratory in the assay of several analytes and enzymes. The use of immobilized enzymes makes these reagents recoverable and re-usable, and in most cases increases their stability and catalytic activity. In conjunction with bioluminescent enzymes
