The problem of ice destruction comes most frequently to our attention in engineering glaciology and ice engineering because it is essential in the solution of many problems in the polar regions of the Earth. Ice destruction (like the destruction of any other material, in principle) is a complex problem at the junction of solid-state physics, continuum mechanics, and materials science. Ice, particularly sea ice, is characterized by known anomalies that can be explained by the simultaneous occurrence of solid, liquid and gaseous phases. Even minor temperature fluctuations cause changes in the relationship of these phases and, as a consequence, change the physico-mechanical properties of ice. New hydraulic engineering tasks, associated with the destruction of such a complex material, demand continuous improvement of methods and techniques. The present authors have brought these together in a form which is convenient for a wide range of users. This book covers only local ice destruction, by means other than icebreakers, requiring comparatively low consumption of power in proportion to the volume and mass of destroyed ice. Problems of natural ice destruction under the influence of solar radiation, tidal, wind and wave factors are not dis cussed. Mechanical and thermal methods were the first of many to be used for ice destruction. Their application has involved a greater num ber of techniques, so the first two chapters are the longest.

Inhibition and Destruction of the Microbial Cell focuses on the effects of various classes of toxic chemical agents on microbial cell. This book is organized into 14 chapters that cover the topics from two points of view: the agent and the target (the microbial cell). The introductory chapters are devoted to the inhibitory effects of elevating temperature and to the lethal effect of environmental thermal energy supply restriction on growing bacteria. A chapter focuses on the effect of various classes of antibacterial compounds, such as 4-amino-quinaldinium and 8-hydroxyquinoline derivatives, chlorhexidine, amidines, halogens, dyes, and nitrofurans. The subsequent chapters examine the effects of other chemical agents on microorganisms, including toxic gases, solutes, ions, and radiations. The book goes on examining the inhibition and destruction of specific microorganisms, such as Pseudomonas aeruginosa, Enterobacteriaceae, Mycobacteria, Cocci, bacterial spores, molds, yeasts, and viruses. The last chapter discusses the effect of the cultural prehistory of microorganisms upon their response to inhibition and destruction. This book is an invaluable resource for graduate research workers and scientists in pure and applied microbiology. This will also be a good reference for undergraduates reading specialized courses at honors level in microbiology or applied courses in food science and agriculture. Furthermore, it will be of interest to the medical profession, especially those involved in public health and pathology, as well as to scientists in the pharmaceutical industry.

The social, political, and cultural consequences of attempts to cheat death by freezing life. As the planet warms and the polar ice caps melt, naturally occurring cold is a resource of growing scarcity. At the same time, energy-intensive cooling technologies are widely used as a means of preservation. Technologies of cryopreservation support global food chains, seed and blood banks, reproductive medicine, and even the preservation of cores of glacial ice used to study climate change. In many cases, these practices of freezing life are an attempt to cheat death. Cryopreservation has contributed to the transformation of markets, regimes of governance and ethics, and the very relationship between life and death. In Cryopolitics, experts from anthropology, history of science, environmental humanities, and indigenous studies make clear the political and cultural consequences of extending life and deferring death by technoscientific means. The contributors examine how and why low temperatures have been harnessed to defer individual death through freezing whole human bodies; to defer nonhuman species death by freezing tissue from endangered animals; to defer racial death by preserving biospecimens from indigenous people; and to defer large-scale human death through pandemic preparedness. The cryopolitical lens, emphasizing the roles of temperature and time, provokes new and important questions about living and dying in the twenty-first century.
