Infection of a susceptible bacterium by a virulent phage particle is followed, after a latent period, by cell lysis and liberation of newly formed phage particles. The infecting particle loses its infectivity shortly after adsorption to the host, a fact attributed to disociation of the particle into a-cell penetrating fraction, consting chiefly of nucleic acid, and an externally persisting frac...

The interannual relationship between the East Asian summer monsoon and the tropical Pacific SSTs is studied using rainfall data in the Yangtze River Valley and the NCEP reanalysis for 1951–96. The datasets are also partitioned into two periods, 1951–77 and 1978–96, to study the interdecadal variations of this relationship. A wet summer monsoon is preceded by a warm equatorial eastern Pacific in...
