Download or read book The Law of Outer Space written by Tanja L. Masson-Zwaan and published by BRILL. This book was released on 2010-09-10 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a remarkable achievement to write a book that almost four decades after its publication has lost virtually none of its relevance. Manfred Lachs’ famous treatise on the Law of Outer Space was originally published in 1972, yet it is still a classic and must-read text for space law students today, even though copies can nowadays be rarely found. The reissue of this remarkable work is therefore timely indeed. Its aim is to make the brilliance, foresight and clarity of Lachs’ thinking once more easily accessible to a new generation of scholars. Issued on the occasion of the 50th anniversary of the International Institute of Space Law, of which Lachs was President, this volume reproduces the original text of Lachs' work in full, with a new preface, introduction and index supplied by the editors.

This book was released on 1996-01-22 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key to opening the use of space to private enterprise and to broader public uses lies in reducing the cost of the transportation to space. More routine, affordable access to space will entail aircraft-like quick turnaround and reliable operations. Currently, the space Shuttle is the only reusable launch vehicle, and even parts of it are expendable while other parts require frequent and extensive refurbishment. NASA's highest priority new activity, the Reusable Launch Vehicle program, is directed toward developing technologies to enable a new generation of space launchers, perhaps but not necessarily with single stage to orbit capability. This book assesses whether the technology development, test and analysis programs in propulsion and materials-related technologies are properly constituted to provide the information required to support a December 1996 decision to build the X-33, a technology demonstrator vehicle; and suggest, as appropriate, necessary changes in these programs to ensure that they will support vehicle feasibility goals.

Book excerpt: A mommy blogger gone bad… Jess McAdams dotes on her four children and gives advice and suggestions to parents all around the world. No one would ever question her love and devotion to her children, let alone suspect her of murdering one. But Alex Mercer does. Alex has plenty of experience investigating crimes involving missing kids. So when he senses something is wrong, he trusts his instincts. He receives a tip that Jess has suddenly stopped posting about one of her children. It’s almost as if he never existed, except her old blog posts show otherwise. The deeper Alex digs, the more twisted and sinister things look... His only chance at finding the proof he needs is by using resources he's been denied. But Alex will stop at nothing until he finds the mommy blogger and saves the children he knows are in danger—even at the risk of losing his dream job—because he knows he's right. And with young lives on the line, there's a lot more at stake than his career. ★★★★★ "What a rollercoaster ride!" ★★★★★ "Riveting thriller!" ★★★★★ "One heck of a read..."

Download or read book Animals and Inequality in the Ancient World written by Benjamin S. Arbuckle and published by University Press of Colorado. This book was released on 2014-12-19 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animals and Inequality in the Ancient World explores the current trends in the social archaeology of human-animal relationships, focusing on the ways in which animals are used to structure, create, support, and even deconstruct social inequalities. The authors provide a global range of case studies from both New and Old World archaeology—a royal Aztec dog burial, the monumental horse tombs of Central Asia, and the ceremonial macaw cages of ancient Mexico among them. They explore the complex relationships between people and animals in social, economic, political, and ritual contexts, incorporating animal remains from archaeological sites with artifacts, texts, and iconography to develop their interpretations. Animals and Inequality in the Ancient World presents new data and interpretations that reveal the role of animals, their products, and their symbolism in structuring social inequalities in the ancient world. The volume will be of interest to archaeologists, especially zooarchaeologists, and classical scholars of pre-modern civilizations and societies.

Download or read book Bound Lives written by Rachel Sarah O'Toole and published by University of Pittsburgh Pre. This book was released on 2012-04-15 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bound Lives chronicles the lived experience of race relations in northern coastal Peru during the colonial era. Rachel Sarah O'Toole examines how Andeans and Africans negotiated and employed casta, and in doing so, constructed these racial categories. Royal and viceregal authorities separated "Indians" from "blacks" by defining each to specific labor demands. Casta categories did the work of race, yet, not all casta categories did the same type of work since Andeans, Africans, and their descendants were bound by their locations within colonialism and slavery. The secular colonial legal system clearly favored indigenous populations. Andeans were afforded greater protections as "threatened" native vassals. Despite this, in the 1640s during the rise of sugar production, Andeans were driven from their assigned colonial towns and communal property by a land privatization program. Andeans did not disappear, however; they worked as artisans, muleteers, and laborers for hire. By the late seventeenth and early eighteenth centuries, Andeans employed their legal status as Indians to defend their prerogatives to political representation that included the policing of Africans. As rural slaves, Africans often found themselves outside the bounds of secular law and subject to the judgments of local slaveholding authorities. Africans therefore developed a rhetoric of valuation within the market and claimed new kinships to protect themselves in disputes with their captors and in slave-trading negotiations. Africans countered slaveholders' claims on their time, overt supervision of their labor, and control of their rest moments by invoking customary practices. Bound Lives offers an entirely new perspective on racial identities in colonial Peru. It highlights the tenuous interactions of colonial authorities, indigenous communities, and enslaved populations and shows how the interplay between colonial law and daily practice shaped the nature of colonialism and slavery.

This book was released on 2018-12-31 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A research and development project on the experimental study of a 1.5-5 kW thermal arcjet thruster was started in 1992 at the IRS. Two radiation cooled thrusters were designed, constructed, and adapted to the test facilities, one at each end of the intended power range. These thrusters are currently subjected to an intensive test program with main emphasis on the exploration of thruster performance and thruster behavior at high specific enthalpy and thus high specific impulse. Propelled by simulated hydrazine and ammonia, the thruster's electrode configuration such as constrictor diameter and cathode gap was varied in order to investigate their influence and to optimize these parameters. In addition, test runs with pure hydrogen were performed for both thrusters. Riehle, M. and Glocker, B. and Auweter-Kurtz, M. and Kurtz, H. NASA-CR-193133, NAS 1.26:193133, IRS-93-P7 NAGW-1736...

This book was released on 2018-07-25 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal objective of this two phase program is to conduct the development research required to make the low power arcjet a flight ready technology. Many important results were obtained during Phase 1 to move closer to this objective. Fundamental analyses were performed of the arcjet nozzle, the gas kinetic reaction effects, the thermal environment, and the arc stabilizing vortex. These aided the conceptual understanding of the arcjet and guided design work. A hydrazine (N2H4) arcjet was designed that combined a flight qualified catalyst bed with a modular arcjet. Extensive testing was performed which demonstrated the feasibility of using this propellant in an arcjet for the first time. Startup techniques were developed, stability maintained, material compatibility tests conducted, and performance mapping tests performed. Specific impulse values from 400 to 730 seconds were produced with a non-optimized design. These levels are higher than were originally thought possible and proved that extremely high enthalpy values can be obtained with constricted arc technology. Erosion rate data are promising for lifetime extensions to meet flight application requirements. Power control unit (PCU) development was started with the design and fabrication of a laboratory high switching frequency supply. Valuable data were obtained on PCU operation and on the interaction with the dynamic arc. Phase 2 efforts presently underway are resolving key issues for multi-hundred hour lifetimes, are continuing to investigate arcjet/PCU interactions, and will demonstrate duty cycle N2H4 arcjet/PCU operation in a simulated flight mode for lifetimes consistent with initial applications.
