    Notes: Abstract. —The mechanism of Kaiser effect was studied with the aid of a damage model for rock. Recognizing that the AE counts are transient elastic waves due to local damage of the rock, the quantitative relation between AE counts and statistical distribution of the local strength of the rock has been established. Subsequently, according to Damage Theory, an expression for Kaiser Effect under uniaxial stress state was derived from the model. This is found to be in good agreement with the experimental results.

    Shoot regeneration from mesophyll protoplasts and leaf explants of Rehmannia glutinosa (1983)

    Notes: Abstract Mesophyll protoplasts obtained from leaves of shoot cultures of Rehmannia glutinosa were cultured in Murashige and Skoog (1962) liquid or liquid-over-agar medium containing 2.0 mg L−1 naphthaleneacetic acid and 0.5 mg L−1 benzylamino purine. An amino acid mixture of glutamine, arginine, glycine, and aspartic acid promoted sustained protoplast division, with an average plating efficiency of 27%. Protoplast-derived colonies formed callus which readily regenerated shoots on fransfer to Murashige and Skoog based agar medium with 2.0 mg L−1 indoleacetic acid and 1.0 mg L−1 benzylamino purine. Leaf explants also showed a marked capacity for shoot regeneration in culture.
