    Notes: Abstract Some subsidiary conditions for determining the superiority of the periodic control to the steady control are derived. The necessary condition for the optimality of period is established by adding a new condition to the well-known condition which can yield merely the stationary value of the objective function. Some considerations are also given for a system having a single state variable and a single control variable and for the linear control problem, which very often appears in many practical cases.

    Notes: Summary Genetic loci for 16S ribosomal RNA (rRNA) on the Escherichia coli chromosome were determined using the K-sequence, a characteristic oligonucleotide of strain K12, as a genetic marker. Oligonucleotide analyses of 16S rRNA from various recombinants between strain K12 and strain B(H) showed that the loci for 16S rRNA containing the K-sequence were near the metB locus which was at 77 min. on the chromosome map.
