Chemistry and Technology of Silicones retains the nature of a monograph despite its expanded scope, giving the reader in condensed form not only a wide-ranging but also a thorough review of this rapidly growing field. In contrast to some other monographs on organosilicon compounds that have appeared in the interim, the silicones occupy in this edition the central position, and the technological part of the work is entirely devoted to them. This book comprises 12 chapters, and begins with a general discussion of the chemistry and molecular structure of the silicones. The following chapters then discuss preparation of silanes with nonfunctional organic substituents; monomeric organosilicon compounds RnSiX4-n; and organosilanes with organofunctional groups. Other chapters cover preparation of polyorganosiloxanes; the polymeric organosiloxanes; other organosilicon polymers; production of technical silicone products from polyorganosiloxanes; properties of technical products; applications of technical silicone products in various branches of industry; esters of silicic acid; and analytical methods. This book will be of interest to practitioners in the fields of molecular chemistry.
Astronomy and Astrophysics Abstracts. which appears in semi-annual volumes, is devoted to the re cording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 3 contains literature published in 1970 and received before August IS, 1970; some older lite rature which was received late and which is not recorded in earlier volumes is also included.
The question "Do black landscapes matter?" cuts deep to the core of American history. From the plantations of slavery to contemporary segregated cities, from freedman villages to northern migrations for freedom, the nation’s landscape bears the detritus of diverse origins. Black landscapes matter because they tell the truth. In this vital new collection, acclaimed landscape designer and public artist Walter Hood assembles a group of notable landscape architecture and planning professionals and scholars to probe how race, memory, and meaning intersect in the American landscape. Essayists examine a variety of U.S. places—ranging from New Orleans and Charlotte to Milwaukee and Detroit—exposing racism endemic in the built environment and acknowledging the widespread erasure of black geographies and cultural landscapes. Through a combination of case studies, critiques, and calls to action, contributors reveal the deficient, normative portrayals of landscape that affect communities of color and question how public design and preservation efforts can support people in these places. In a culture in which historical omissions and specious narratives routinely provoke disinvestment in minority communities, creative solutions by designers, planners, artists, and residents are necessary to activate them in novel ways. Black people have built and shaped the American landscape in ways that can never be fully known. Black Landscapes Matter is a timely and necessary reminder that without recognizing and reconciling these histories and spaces, America’s past and future cannot be understood.
Unlikely pig owners Steve and Derek got a whole lot more than they bargained for when the designer micro piglet they adopted turned out to be a full-sized 600-pound sow! This funny, inspirational story shows how families really do come in all shapes and sizes. In the summer of 2012, Steve Jenkins was contacted by an old friend about adopting a micro piglet. Though he knew his partner Derek wouldn't be enthusiastic, he agreed to take the adorable little pig anyway, thinking he could care for her himself. Little did he know, that decision would change his and Derek's lives forever. It turned out there was nothing "micro" about Esther, and Steve and Derek had actually signed on to raise a full-sized commercial pig. Within three years, Tiny Esther grew to a whopping 600 pounds. After some real growing pains and a lot of pig-sized messes, it became clear that Esther needed much more space, so Steve and Derek made another life-changing decision: they bought a farm and opened the Happily Ever Esther Farm Sanctuary, where they could care for Esther and other animals in need. Funny, heartwarming, and utterly charming, Esther the Wonder Pig follows Steve and Derek's adventure--from reluctant pig parents to farm-owning advocates for animals.

By 1760, with the alleviation of the French threat to the western frontier, colonial fur traders headed west to reap the bounty of trade with the local tribes. However, when dissatisfied French interests conspired to instigate a revolt, the resulting Pontiac Uprising would force the British to rethink colonial trade policy. The fur traders, who had considered the British government their ally in exploiting the west, now saw the British allying themselves with the French and local tribes to keep the colonists out of the region. The prominent merchants who suffered financially and received no compensation would soon come to oppose British rule. The fur trade and land speculation were two driving forces in the westward spread of merchant interests, but the promise of such riches would remain unfulfilled. Regulation of the trade would prove an enormous expense for the British; thus, to avoid the financial burden as well as to remove ill-treatment of the Native Americans as a cause for conflict, the Proclamation of 1763 prohibited settlement west of the mountains. The resulting dissatisfaction among the traders and speculators cost the British the support of colonial merchants. This book is an informative account of the interaction of economic, political, and social concerns on the western frontier.

This book has once again been updated to keep pace with recent developments and to maintain Koechner's position as "the bible" of the field. Written from an industrial perspective, it provides a detailed discussion of, and data for, solid-state lasers, their characteristics, design and construction.
This volume is the first comprehensive overview of North Carolina Presbyterians to appear in more than a hundred years. Drawing on congregational and administrative histories, personal memoirs, and recent scholarship—while paying close attention to the relevant social, political, and religious contexts of the state and region—Walter Conser and Robert Cain go beyond older approaches to denominational history by focusing on the identity and meaning of the Presbyterian experience in the Old North State from the seventeenth through the twentieth centuries. Conser and Cain explore issues as diverse as institutional development and worship experience; the patterns and influence of race, ethnicity, and gender; and involvement in education and social justice campaigns. In part 1 of the book, “Beginnings,” they trace the entrance of Presbyterians—who were legally considered dissenters throughout the colonial period—into the eastern, central, and western sections of the state. The authors show how the Piedmont became the nexus of Presbyterian organizational development and examine the ways in which political movements, including campaigns for American independence, deeply engaged Presbyterians, as did the incandescence of revivalism and agitation for reform, which extended into the antebellum period. The book’s second section, “Conflict, Renewal, and Reunion,” investigates the denominational tensions provoked by the slavery debate and the havoc of the Civil War, the soul searching that accompanied Confederate defeat, and the rebuilding efforts that came during the New South era. Such important factors as the changing roles of women in the church and the decline of Jim Crow helped pave the way for the eventual reunion of the northern and southern branches of mainline Presbyterianism. By the arrival of the new millennium, Presbyterians in North Carolina were prepared to meet future challenges with renewed confidence. A model for modern denominational history, this book is an astute and sensitive portrayal of a prominent Protestant denomination in a southern context. Walter H. Conser Jr. is professor of religion and professor of history at the University of North Carolina, Wilmington. His books include A Coat of Many Colors: Religion and Society along the Cape Fear River of North Carolina and God and the Natural World: Religion and Science in the Natural World. Before his retirement after thirty-two years of service, Robert J. Cain was head of the Colonial Records Branch at the North Carolina State Archives. He is the editor of The Colonial Records of North Carolina, second series.
