Mercury - - Bog - Cambridge University Press - Plusbog.dk

Observations from the first spacecraft to orbit the planet Mercury have transformed our understanding of the origin and evolution of rocky planets. This volume is the definitive resource about Mercury for planetary scientists, from students to senior researchers. Topics treated in depth include Mercury''s chemical composition; the structure of its crust, lithosphere, mantle, and core; Mercury''s modern and ancient magnetic field; Mercury''s geology, including the planet''s major geological units and their surface chemistry and mineralogy, its spectral reflectance characteristics, its craters and cratering history, its tectonic features and deformational history, its volcanic features and magmatic history, its distinctive hollows, and the frozen ices in its polar deposits; Mercury''s exosphere and magnetosphere and the processes that govern their dynamics and their interaction with the solar wind and interplanetary magnetic field; the formation and large-scale evolution of the planet; and current plans and needed capabilities to explore Mercury further in the future.

Ecosystem Responses to Mercury Contamination - - Bog - Taylor & Francis Ltd - Plusbog.dk

Ecosystem Responses to Mercury Contamination - - Bog - Taylor & Francis Ltd - Plusbog.dk

As rising levels of mercury in the environment pose an increasing threat of toxicity to humans and wildlife, several laws already call for industries to reduce mercury emissions at the source. Ecosystem Responses to Mercury Contamination: Indicators of Change outlines the infrastructure and methods needed to measure, monitor, and regulate the concentration of mercury present in the environment. This book draws on the knowledge of forty international experts in the fields of atmospheric transport and deposition, mercury cycling in terrestrial and aquatic ecosystems, and mercury bioaccumulation in aquatic foodwebs and wildlife. The authors propose a set of indicators to use as a measure of changing mercury concentrations in the environment. Next, they recommend a monitoring strategy and offer guidance for determining systematic changes in concentration. Then the authors examine additional monitoring strategies to relate observed changes in concentration to regulatory controls on mercury emissions. The final chapter provides an integrated framework for establishing a national-scale program to monitor mercury concentrations in the environment. Ecosystem Responses to Mercury Contamination: Indicators of Change contains the information needed to design a large-scale monitoring program for mercury and to use the concentration data to create, enforce, and evaluate the progress of initiatives aimed at reducing mercury emissions.

Gemini and Mercury Remastered - Andy Saunders - Bog - Penguin Books Ltd - Plusbog.dk

Gemini and Mercury Remastered - Andy Saunders - Bog - Penguin Books Ltd - Plusbog.dk

Embark on a captivating photographic journey beyond Earth, from the dawn of human space exploration, through the untold story of the Mercury and Gemini missions ''Wickedly exciting'' Tom Hanks ''Experience the same incredible awe as we astronauts did on those very first voyages into space'' Jim Lovell, Gemini 7 & 12, Apollo 8 & 13 ''An unprecedented trip back in time… a vibrant, new, living record'' Gene Kranz, Flight Director Mercury, Gemini, Apollo When we think of the history of space exploration, we can’t help but think of the Apollo missions and Neil Armstrong’s one giant leap. But what about the small steps that enabled NASA to reach for the Moon? Astronauts working on the earliest space missions, from Project Mercury to the Gemini missions of the mid-1960s, answered fundamental questions about the possibilities of long-duration space travel, paving the way for the Apollo missions and, ultimately, the Moon landings. They also took the first, and still some of the finest, images of Earth ever captured on film. Now, the bestselling author of Apollo Remastered, Andy Saunders has restored images from these first missions to show them in unprecedented detail and tell their full story, filled with dramatic life or death moments, mischievous pranks and astonishing triumphs. This stunning visual odyssey brings to life the pivotal, intimate moments of early space travel, unveiling the raw beauty and profound challenges faced by the pioneering astronauts pushing the boundaries of human achievement. Gemini and Mercury Remastered is a striking tribute to the visionaries who dared to dream beyond our world and a testament to the enduring power of exploration.

Stability and Trim for the Ship’s Officer - William E. George - Bog - Schiffer Publishing Ltd - Plusbog.dk

Stability and Trim for the Ship’s Officer - William E. George - Bog - Schiffer Publishing Ltd - Plusbog.dk

Stability and Trim for the Ship’s Officer has been completely updated after twenty-two years. Aboard today’s vessels, technology and computers abound as ship’s gear. The once long and tedious calculations for stability, trim, and hull strength are now done in minutes. But no matter how much change the industry has undergone, the laws of physics are constant. The only way to verify that the computer is coming up with accurate figures is to read the ship’s drafts. Two new chapters have been included, “Prerequisites for Stability, Trim, and Hull Strength Calculations,” and “U.S. Coast Guard Questions on Stability, Trim, and Longitudinal Hull Strength.” The appendix has also been updated to include the Stability Data Reference Book—August 1989 Edition, which is the same supplied in the United States Coast Guard license examination room.

Quicksilver - Richard M. Swiderski - Bog - McFarland & Co Inc - Plusbog.dk

Quicksilver - Richard M. Swiderski - Bog - McFarland & Co Inc - Plusbog.dk

Though modern scientists recognize mercury as a harmful environmental pollutant and one of the world''s most dangerous elemental toxins, mercury was once considered a wondrous substance capable of eradicating internal disease, revolutionizing the paint and cosmetics industries and even entertaining the masses as part of amateur magic tricks and witch doctor scams. This work traces the history of mercury in popular culture, beginning in the early eighteenth century when Dr. Thomas Dover, nicknamed "Dr. Quicksilver," began prescribing doses of raw mercury to clear out intestinal blockages and rid the body of syphilis and other diseases. The author then details the role of mercury in several medical, industrial, and cultural applications. In the fields of dentistry and vaccination, mercury continues to be used as a preservative and amalgamative agent. In the cosmetics industry, mercury was once used as a popular "skin lightener" in soaps and skin creams. In the early development of obstetrics and gynecology, mercury was once used to stimulate conception and fetal abortion. Many more uses of mercury, along with many more, are outlined in the work, while several appendices provide translations of rare works which reference mercury.

Selecting the Mercury Seven - Colin Burgess - Bog - Springer-Verlag New York Inc. - Plusbog.dk

Selecting the Mercury Seven - Colin Burgess - Bog - Springer-Verlag New York Inc. - Plusbog.dk

The names of the seven Mercury astronauts were announced in April 1959 amid a flurry of publicity and patriotism. This work provides biographical details of all thirty-two finalists for the seven coveted places as America''s pioneering astronauts. All of the candidates were among the nation''s elite pilots involved in testing new supersonic aircraft capabilities. Most had served as wartime fighter and bomber pilots; some were test pilots on top secret and sophisticated aviation projects, while others were fleet admirals, prisoners of war, and proposed pilots for spaceflight programs such as the Dyna-Soar (X-20). The names of all 32 finalists have been kept secret until very recently. "Selecting the Mercury Seven" also relates the history and difficulties behind the initial choice of candidates. The lives, motivations, military careers, and achievements of the unsuccessful twenty-five finalists are explored first in fully authorized biographies. Test pilots for the U.S. Navy, Air Force, and Marine Corps, each man has a fascinating and very different story to tell. All thirty-two men had to endure meticulous, demeaning, and brutal week-long medical examinations at the Lovelace Clinic in New Mexico. This was followed by another torturous week at the Wright Aeromedical Laboratory in Ohio, where they were subjected to extreme fitness and physiological testing, the sole purpose of which was to sort out the Supermen from the near-supermen. The final part of the book examines the accomplishments and spaceflights of the seven successful candidates, bringing their amazing stories right up to date.
