Prima edizione
Pamphlet/Booklet. Condizione: Very good. Andrea Gaskey (Illustrator) and Gary Warren (Photo (illustratore). Presumed First Edition, First printing. 20 pages plus covers. Illustrations (color). Diagrams. Definitions. Cover has slight wear and soiling. The Dual-Axis Radiographic Hydrodynamic Test Facility (DARHT) is a facility at Los Alamos National Laboratory which is part of the Department of Energy's stockpile stewardship program. It uses two large X-ray machines to record three-dimensional interior images of materials. In most experiments, materials undergo hydrodynamic shock to simulate the implosion process in nuclear bombs and/or the effects of severe hydrodynamic stress. The tests are described as "full-scale mockups of the events that trigger the nuclear detonation". The powerful pulsed X-ray beams allow for an ultra-fast motion picture to be constructed showing the details of the process being studied in three dimensions. The tests are often compared with computer simulations to help improve the accuracy of the computer code. Such testing falls under the category of sub-critical testing. The project became an important priority after the United States stopped testing nuclear weapons in 1992. When completed in 1999, the first-axis accelerator could produce one short electron pulse lasting 60 ns with a current of 2 kA and an energy of 20 MeV. The beam could be focused to 2-millimeter diameter spot on the target. During a weapon's crucial triggering phase, explosive charges that surround the nuclear fuel are detonated at multiple points. The result is a shock wave that moves inward (implosion) at supersonic speeds, compressing the fuel to higher and higher density. Implosion ends when the fuel reaches a supercritical density, the density at which nuclear reactions in the fuel build up an uncontainable amount of energy, which is then released in a massive explosion. To make the mockup non-nuclear, a heavy metal surrogate (such as depleted uranium or lead) stands in for the nuclear fuel, but all other components can be exact replicas. Sub-critical masses of plutonium may also be used. Under such extreme implosion forces materials tend to behave like fluids, so this mock implosion is called a hydrodynamic test, or hydrotest. Standard practice is to take a single stop-action snapshot of the weapon mockup's interior as the molten components rush inward at thousands of meters per second. X-rays that can penetrate the heavy metal in a weapon mockup are made with an electron accelerator. An electron beam moving at near the speed of light is smashed into a tungsten target. The electrons are yanked off course by the strong electrostatic pull of the positively charged nuclei in the tungsten atoms, and their sudden change in direction causes them to give off energy in the form of high-energy x-rays. Scientists already knew how to use a short burst (pulse) of high-energy electrons (rather than a continuous beam) to make a short pulse of high-energy x-rays. The new challenge was for the accelerator to deliver a very large number of electrons in an extremely powerful pulse to generate an x-ray flash that can penetrate the mockup during the ultra-dense implosion. Specifications call for a pulse of 100 billionths of a second, about a million times shorter than exposures achieved with a high-end conventional camera. As with the hole in a pinhole camera, the smaller the beam spot, the more point-like the area producing x-rays, and the sharper the resulting image. Each electron accelerator consists of a long row of doughnut-shaped magnetic induction cells, each connected to a high-voltage generator. There are 74 in total in each accelerator but not all may be used. At the instant of firing, each generator discharges its power, creating a pulse of electric current through its induction cell, which in turn creates a large voltage difference across the gap separating that cell from its neighbor. The electron beam-pulse travels through the central bore of the cells, receiving a 200 keV energy kick each time it passes though a gap. One of the design problems was designing the new induction c.

Paperback. Condizione: new. Paperback. Culture and Customs of Guatemala proffers a well rounded portrait of the people of the land known for breathtaking highlands, brilliantly colored Mayan textiles, generations of ruthless dictators, and violence against the Mayas since the Spanish conquest. This Central American hotspot is the home to a majority of Mayas, their coexistence with Ladinosthe nonMayas, and the issue of land ownership provide the framework for understanding contemporary society. The blend of Mayan and Ladino cultural identities that shape Guatemala today permeates Shea's discussion of history, religion, social customs, media, literature, cinema, performing arts, and contemporary art. Students and other interested readers will come to understand how the traditions and reforms are shaping Guatemala in the 21-first century.After an overview of Guatemalan history, geography, and demographics, a chapter on religion reveals the prevalent mixture of Catholic/Spanish and indigenous influences. In the Social Customs chapter, customs and festivals, many related to Catholic saints' days, the importance of Mayan weaving, and Guatemalan cuisine are emphasized. The recent lessening of censorship is a factor in the discussions of the status of broadcasting and print media and a small but emerging film industry. In the Literature chapter, Shea portrays a rich centuries-old literary tradition influenced by pre and post conquest indigenous texts and contemporary experimental trends whose themes are saturated in the country's social conflicts. Coverage of performing arts and contemporary art is evocative of the vibrant mixtures of cultures in Guatemala, with notable artists introduced and a description of architecture and housing. A chronology and glossary enhance the text. The blend of Mayan and Ladino cultural identities that shape Guatemala today permeates Shea's discussion of history, religion, social customs, media, literature, cinema, performing arts, and contemporary art.
