Download or read book Magmatic Systems written by Michael P. Ryan and published by Academic Press. This book was released on 1994-08-26 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: With its integrated and cohesive coverage of the current research, Magmatic Systems skillfully explores the physical processes, mechanics, and dynamics of volcanism. The text utilizes a synthesized perspective--theoretical, experimental, and observational--to address the powerful regulatory mechanisms controlling the movement of melts and cooling, with emphasis on mantle plumes, mid-ocean ridges, and intraplate magmatism. Further coverage of subduction zone magmatism includes:Fluid mechanics of mixed magma migrationInternal structure of active systemsGrain-scale melt flowRheology of partial meltsNumerical simulation of porous media melt migrationNonlinear (chaotic and fractal) processes in magma transportIn all, Magmatic Systems will prove invaluable reading to those in search of an interdisciplinary perspective on this active topic. Key Features* Fluid mechanics of magma migration from surface region to eruption site* Internal structure of active magmatic systems* Grain-scale melt flow in mantle plumes and beneath mid-ocean ridges* Physics of magmatic systems and magma dynamics

Download or read book Using Science to Improve the BLM Wild Horse and Burro Program written by National Research Council and published by National Academies Press. This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Available in PDF, EPUB and Kindle. Book excerpt: Documents how 12 people, as part of a top-secret U.S. government program, traveled to the planet Serpo and lived there for 13 years • Based on the debriefing of the Serpo team and the diary of the expedition’s commander • Explains how the aliens helped us reverse-engineer their antigravity spacecraft and develop technology to solve our planet-wide energy problems • Reveals how our government has an ongoing relationship with the Serpo aliens On July 16, 1965, a massive alien spacecraft from the Zeta Reticuli star system landed at the Nevada test site north of Las Vegas. Following a plan set in motion by President Kennedy in 1962, the alien visitors known as the Ebens welcomed 12 astronaut-trained military personnel aboard their craft for the 10-month journey to their home planet, Serpo, 39 light-years away. In November 2005, former and current members of the Defense Intelligence Agency--directed by Kennedy to organize the Serpo exchange program--came forward to reveal the operation, including details from the 3,000-page debriefing of the 7 members of the Serpo team who returned after 13 years on the planet. Working with the DIA originators of the Serpo project and the diary kept by the expedition’s commanding officer, Len Kasten chronicles the complete journey of these cosmic pioneers, including their remarkable stories of life on an alien planet, superluminal space travel, and advanced knowledge of alien technologies. He reveals how the Ebens presented the U.S. with “The Yellow Book”--a complete history of the universe recorded holographically, allowing the reader to view actual scenes from pre-history to the present. He explains how the Ebens helped us reverse-engineer their antigravity spacecraft and develop technology to solve our planet-wide energy problems--knowledge still classified. Exposing the truth of human-alien interaction and interplanetary travel, Kasten reveals not only that the Ebens have returned to Earth eight times but also that our government continues to have an ongoing relationship with them--a relationship with the potential to advance the human race into the future.

Book excerpt: This report discusses the findings of a nationwide study on the use of private prisons in the United States. The number of these prisons grew enormously between 1987 and 1998, with proponents suggesting that allowing facilities to be operated by the private sector could result in cost reductions of 20%. The study examined the historical factors that gave rise to the higher incarceration rates, fueling the privatization movement, and the role played by the private sector in the prison system. It outlines the arguments, both in support of and opposition to, privatized prisons, reviews current literature on the subject, and examines issues that will have an impact on future privatizations. The report concludes that, rather than the projected 20-percent savings, the average saving from privatization was only about 1 percent, and most of that was achieved through lower labor costs. Nevertheless, there were indications that the mere prospect of privatization had a positive effect on prison administration, making it more responsive to reform.

Available in PDF, EPUB and Kindle. Book excerpt: Cities in the arid West would not be what they are today without water and the technology needed to deliver it to users. The history of water development in Arizona goes hand in hand with the state's economic growth, and Arizona's future is inextricably tied to this scarce resource. Fuel for Growth describes and interprets the history of water resource development and its relationship to urban development in Arizona's three signature cities: Phoenix, Tucson, and Flagstaff. These three urban areas could hardly be more different: a growth-oriented metropolis, an environmentally conscious city with deep cultural roots, and an outdoor-friendly mountain town. Despite these differences, their community leaders and public officials have taken similar approaches to developing water resources with varying degrees of success and acceptance. Douglas Kupel has created a new vision of water history based on the Arizona experience. He challenges many of the traditional assumptions of environmental history by revealing that the West's aridity has had relatively little impact on the development of municipal water infrastructure in these cities. While urban growth in the West is often characterized as the product of an elite group of water leaders, the development of Arizona's cities is shown to reflect the broad aspirations of all their citizens. The book traces water development from the era of private water service to municipal ownership of water utilities and examines the impact of the post-World War II boom and subsequent expansion. Taking in the Salt River Project, the Central Arizona Project, and the Groundwater Management Act of 1980, Kupel explores the ongoing struggle between growth and environmentalism. He advocates public policy measures that can sustain a water future for the state. As the urban West enters a new century of water management, Arizona's progress will increasingly be tied to that of its ever-expanding cities. Fuel for Growth documents an earlier era of urban water use and provides important recommendations for the future path of water development in the West's key population centers.
