    Notes: Abstract Camellia leaves were most effective for recoveringPhytophthora cinnamomi from soils followed by azalea leaves and cedar needles. A total of 131 isolates ofP. cinnamomi was obtained from soils and roots collected in Shanghai. Among them 125 were A1 and 6 were A2 type. There was little variation in morphological and physiological characteristics among 82 isolates tested. It is suggested that the fungus may have been a recent settler in Shanghai.

    Quantization from motion equations (1993)
    Springer
    International journal of theoretical physics 32 (1993), S. 1409-1422 
    Details
    ISSN: 1572-9575
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract All existing quantization methods require a Lagrangian (or Hamiltonian) formulation for classical systems, while many classical systems do not possess Lagrangian descriptions (Helmholtz condition) and cannot be quantized by existing quantization methods. To make more classical systems quantizable, a new quantization procedure is proposed that skips the intermediate steps of Lagrangian description and starts directly from classical motion equations.
