This book presents a summary of the application and instrumentation of cell electrophoresis. The method of making cell purification and characterization possible according to the cellular negative surface charge density is discussed, and ideas for future developments are explained. The negative electrostatic forces at cell surfaces provide information about cell-cell interaction, blood vessel sealing, cytokine actions, cell transformation, ion transport phenomena, and other biological phenomena. Recalculations of the physical principles of cell electrophoresis reveal possibilities for removing disruptive factors caused by electrical current, heat, and sedimentation. The introduction of computer technology, the performance of simultaneous two-parameter measurements, and the application of cell-friendly but current-inert buffer systems render the method more reliable and efficient.

Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
