Cities and Their Vital Systems


Book Description

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.










Physical Forces and the Mammalian Cell


Book Description

This book examines the physical forces - fluid shear, stretch, and gravity that play a role in the physiology of tissues and cellular functions. It gives special attention to the influences of the flow of blood and exercise on the growth of blood vessels and the flow of interstitial fluid on bone formation. Pathological conditions are also presented, such as the lack of mechanical loading on bone and osteoporosis. For biotechnologists, the problem of cell susceptibility to agitation-induced hydrodynamic forces in the scale-up of mammalian cell bioreactors is examined.
