Structured Programming (A.P.I.C. studies in data processing, no. 8)

This book is the classic text in the art of computer programming. The first section represents an initial outstanding contribution to the understanding of the design of programs and the use of structured programming. The second part describes how similar principles can be applied in the design of data structures. The final section provides a synthesis of the previous two and expounds the close theoretical and practical connections between the design of data and the design of programs. This book is designed to critically review experimental findings on ionic polymers and colloidal particles and to prove a theoretical framework based on the Poisson-Boltzmann approach. Structure formation in ionic polymer solutions has attracted attention since the days of H. Staudinger and J. D. Bernal. An independent study on ionic colloidal dispersions with microscopy provided a compelling evidence of structure formation. Recent technical developments have made it possible to accumulate relevant information for both ionic polymers and colloidal particles in dilute systems. The outstanding phenomenon experimentally found is microscopic inhomogeneity in the solute distribution in macroscopically homogeneous systems.To account for the observation, the present authors have invoked the existence of the counterion-mediated attraction between similarly charged solute species, in addition to the widely accepted electrostatic repulsion.
