Tom Clancy's Op-Center: Dark Zone


Book Description

Former US Ambassador to the Ukraine Douglas Flannery meets with an old friend and former spy near New York’s South Street Seaport. She is seeking his help to thwart a Russian plan to overrun her native Ukraine, but those for whom she is working propose an infinitely more dangerous scheme, one that could draw in NATO forces and possibly ignite World War III. Moments later, as she jogs along the East River, her throat is slashed. Within hours, Op-Center learns of the killing and alarm bells go off. Director Chase Williams and his team have been following events as both Ukraine, her NATO allies, and Russia rapidly deploy forces in a dangerous game of brinksmanship. But the secret that Flannery has learned threatens to take the looming battle to a whole new and very lethal level. Using cutting edge techniques of cyber warfare and spycraft, Op-Center must respond to the rapidly unfolding crisis before the U.S. is forced to take sides in a conflict that could change history.

The Dark Zone


Book Description

Over the past twenty years in Gujarat, technological changes in agricultural and intensive use of groundwater have led to a spurt in water markets. The development of competitive markets, dependent on the sinking of tubewells, has been advocated on the basis of efficiency and accessibility to the resource. However, this has generally been done without unpacking nuances of unequal social relationships, ecological and historical functions that shape groundwater access and use. The Dark Zone aims to fill this gap. It focuses on the politics of groundwater markets and its interrelation with social differentiation and class-caste relations. Based on an intensive social anthropological study of a village in north Gujarat, the book investigates the factors that shaped unrestrained use of groundwater and the responses of various social groups to this process. Using a triadic framework of the theory of agrarian institutions, ecological variables in agrarian change and the influence of the state, Prakash locates the study in the larger political economy of Gujarat. Drawing upon rich empirical material, the book should interest anthropologists, sociologists, researchers, policy makers, NGOs and water resource specialists.




The Dark Zone


Book Description

When the tail of the comet Bhaktul flicks through the Earth's atmosphere, deadly particles are left in its wake, and mankind is confronted with a virus that devastates the adult population. A renowned scientist proposes a bold plan: to build a ship that will carry a crew of 251 teenagers to a home in a distant solar system. Two years later, Galahad and its crew is launched. If their mission fails, it will be the end of the human race... With the help of the mysterious alien force known as The Cassini, the teenage crew of Galahad has managed to navigate safely through the minefield of the Kuiper Belt. But just as they exit the belt, they are confronted by their next challenge: a group of incredibly fast and maneuverable organisms waiting in their path—like vultures. With no way of knowing if the organisms are friends or foes, Triana and her Council decide to push forward, setting into motion a chain of events that will lead to the opening of a wormhole (a shortcut across space and time), and the first death aboard Galahad....

Dark Tongues


Book Description

An exploration of secret languages, moving among hermetic artificial tongues as diverse as criminal jargons and divine speech. Dark Tongues constitutes a sustained exploration of a perplexing fact that has never received the attention it deserves. Wherever human beings share a language, they also strive to make from it something new: a cryptic idiom, built from the grammar that they know, which will allow them to communicate in secrecy. Such hidden languages come in many shapes. They may be playful or serious, children's games or adults' work. They may be as impenetrable as foreign tongues, or slightly different from the idioms from which they spring, or barely perceptible, their existence being the subject of uncertain, even unlikely, suppositions. The first recorded jargons date to the time of the Renaissance, when writers across Europe noted that obscure languages had suddenly come into use. A varied cast of characters--lawyers, grammarians, and theologians--denounced these new forms of speech, arguing that they were tools of crime, plotted in tongues that honest people could not understand. Before the emergence of these modern jargons, however, the artificial twisting of languages served a different purpose. In epochs and regions as diverse as archaic Greece and Rome and medieval Provence and Scandinavia, singers and scribes also invented opaque varieties of speech. They did so not to defraud, but to reveal and record a divine thing: the language of the gods, which poets and priests alone were said to master. Dark Tongues moves among these various artificial and hermetic tongues. From criminal jargons to sacred idioms, from Saussure's work on anagrams to Jakobson's theory of subliminal patterns in poetry, from the arcane arts of the Druids and Biblical copyists to the secret procedure that Tristan Tzara, founder of Dada, believed he had uncovered in Villon's songs and ballads, Dark Tongues explores the common crafts of rogues and riddlers, which play sound and sense against each other.

Sturdevant's Art and Science of Operative Dentistry


Book Description

This comprehensive text presents a detailed, heavily illustrated, step-by-step approach to restorative and preventive dentistry. It draws from both theory and practice, and is supported by extensive clinical and laboratory research. Based upon the principle that dental caries is a disease, not a lesion, the book provides both a thorough understanding of caries and an authoritative approach to its treatment and prevention. Now offering a companion Evolve website, this new edition has been updated to address the latest developments in an ever-changing field. Comprehensive coverage of operative dentistry includes fundamentals, diagnosis, instrumentation, preparation, restoration, and prevention, all within a single volume. Up-to-date information covers insurance, safety, and infection control, based on the latest reports and guidelines from organizations such as OSHA and ADA. A clear, consistent presentation describes each restorative process in a linear pattern: initial clinical procedures, tooth preparation, and then restorative technique. Procedural alternatives include multiple approaches to problems wherever applicable, teaching how to adapt a procedure or technique to answer individual patient needs. Pros and cons of restoration options include advantages, disadvantages, indications, and contraindications for restorations. A course-based presentation of topics follows that of many operative dentistry courses, making students' absorption of content stronger and more efficient. 2,550 illustrations include 700 high-quality half-tones and line drawings - more illustrations than any other operative dentistry text. Full-color clinical photos illustrate important concepts - such as coloration and shading on both natural teeth and prostheses. Computer assisted design and computer assisted machining (CAD/CAM) is incorporated into the practice of operative dentistry and related to techniques. Esthetic dentistry instruction is included for this increasingly popular area. Chapter outlines begin each chapter and highlight important topics. Extensive references direct readers to current resources available for additional research. A revised organization groups chapters into five sections, so that locating specific chapters or topics is easier and more efficient: 1. Fundamentals of Operative Dentistry 2. Instrumentation and Preparation 3. Composite Restorations 4. Amalgam Restorations 5. Metal Restorations Procedural Boxes offer step-by-step guides to important procedures, with each step accompanied by a corresponding image.
