Gold-Catalyzed Cycloisomerization Reactions Through Activation of Alkynes
by Antoine SimonneauAntoine Simonneau's thesis highlights the development of new cycloisomerization reactions through the activation of alkynes with gold complexes. First Simonneau describes 1,6-enynes and their direct conversion into allenes through 1,5-hydride or ester migration processes. The author and his team used appropriate propargylic functional groups to achieve this conversion. This study shows that O-tethered 1,6-enynes carrying a strained cycloalkane at the propargylic position could undergo a cyclopropanation/ring expansion cascade reaction. The author employed this rearrangement as the starting point in the design of a new macro cycle synthesis. The next part of the thesis focuses on the cycloisomerization of diynes involving as the first step of the process the rearrangement of one alkyne partner into an allene thanks to a gold-catalyzed 1,3-shift of a propargylic ester. The thesis discloses a new cycloisomerization pattern featuring a 1,5-carbonyl transfer, giving rise to unprecedented cross-conjugated diketones. In the final part of the research, Simmoneau investigates the gold-catalyzed cycloisomerization mechanism of 1,6-enynes and questions the intermediacy of gold acetylides. By the means of NMR and mass spectrometry analysis, theoretical treatment and solution experiments, it was possible to rule out the involvement of these species in the catalytic cycle. This thesis has led to a number of publications in high-impact journals.
Gold Clusters, Colloids and Nanoparticles II
by D. Michael P. MingosThe series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink. com

Gold Metal Waters: The Animas River and the Gold King Mine Spill
by Brad T. Clark Pete McCormickGold Metal Waters presents a uniquely inter- and transdisciplinary examination into the August 2015 Gold King Mine spill in Silverton, Colorado, when more than three million gallons of subterranean mine water, carrying 880,000 pounds of heavy metals, spilled into a tributary of the Animas River. The book illuminates the ongoing ecological, economic, political, social, and cultural significance of a regional event with far-reaching implications, showing how this natural and technical disaster has affected and continues to affect local and national communities, including Native American reservations, as well as agriculture and wildlife in the region. This singular event is surveyed and interpreted from multiple diverse perspectives—college professors, students, and scientists and activists from a range of academic and epistemological backgrounds—with each chapter reflecting unique professional and personal experiences. Contributors examine both the context for this event and responses to it, embedding this discussion within the broader context of the tens of thousands of mines leaking pollutants into waterways and soils throughout Colorado and the failure to adequately mitigate the larger ongoing crisis. The Gold King Mine spill was the catalyst that finally brought Superfund listing to the Silverton area; it was a truly sensational event in many respects. Gold Metal Waters will be of interest to students and scholars in all disciplines, but especially in environmental history, western history, mining history, politics, and communication, as well as general readers concerned with human relationships with the environment.

Gold Nanoparticles in Biomedical Applications
by Lev Dykman Nikolai KhlebtsovThis book discusses fabrication of functionalized gold nanoparticles (GNPs) and multifunctional nanocomposites, their optical properties, and applications in biological studies. This is the very first book of its kind to comprehensively discuss published data on in vitro and in vivo biodistribution, toxicity, and uptake of GNP by mammalian cells providing a systematization of data over the GNP types and parameters, their surface functionalization, animal and cell models. As distinct from other related books, Gold Nanoparticles in Biomedical Applications discusses the immunological properties of GNPs and summarizes their applications as an antigen carrier and adjuvant in immunization for the preparation of antibodies in vivo. Although the potential of GNPs in nanobiotechnology has been recognized for the past decade, new insights into the unique properties of multifunctional nanostructures have recently emerged. With these developments in mind, this book unites ground breaking experimental data with a discussion of hybrid nanoparticle systems that combine different nanomaterials to create multifunctional structures. These novel hybrids constitute the material basis of theranostics, bringing together the advanced properties of functionalized GNPs and composites into a single multifunctional nanostructure with simultaneous diagnostic and therapeutic functions. Such nanohybrids can be physically and chemically tailored for a particular organ, disease, and patient thus making personalized medicine available.

Gold Rush in the Jungle: The Race to Discover and Defend the Rarest Animals of Vietnam's "Lost World"
by Dan DrolletteAn engrossing, adventure-filled account of the rush to discover and save Vietnam's most extraordinary animals Deep in the jungle where the borders of Vietnam meet those of Laos and Cambodia is a region known as "the lost world." Large mammals never seen before by Western science have popped up frequently in these mountains in the last decade, including a half-goat/half-ox, a deer that barks, and a close relative of the nearly extinct Javan rhino. In an age when scientists are excited by discovering a new kind of tube worm, the thought of finding and naming a new large terrestrial mammal is astonishing, and wildlife biologists from all over the world are flocking to this dangerous region. The result is a race between preservation and destruction. Containing research gathered from famous biologists, conservationists, indigenous peoples, former POWs, ex-Viet Cong, and the first U.S. ambassador to Vietnam since the war's end, Gold Rush in the Jungle goes deep into the valleys, hills, and hollows of Vietnam to explore the research, the international trade in endangered species, the lingering effects of Agent Orange, and the effort of a handful of biologists to save the world's rarest animals.
The Golden and Ghoulish Age of the Gibbet in Britain (Palgrave Historical Studies in the Criminal Corpse and its Afterlife)
by Sarah TarlowThis book is open access under a CC BY 4.0 licence. This book is the first academic study of the post-mortem practice of gibbeting (‘hanging in chains’), since the nineteenth century. Gibbeting involved placing the executed body of a malefactor in an iron cage and suspending it from a tall post. A body might remain in the gibbet for many decades, while it gradually fell to pieces. Hanging in chains was a very different sort of post-mortem punishment from anatomical dissection, although the two were equal alternatives in the eyes of the law. Where dissection obliterated and de-individualised the body, hanging in chains made it monumental and rooted it in the landscape, adding to personal notoriety. Focusing particularly on the period 1752-1832, this book provides a summary of the historical evidence, the factual history of gibbetting which explores the locations of gibbets, the material technologies involved in hanging in chains, and the actual process from erection to eventual collapse. It also considers the meanings, effects and legacy of this gruesome practice.
Golden Lads: Sir Francis Bacon, Anthony Bacon, and Their Friends
by Daphne Du Maurier"Daphne du Maurier has no equal." --Sunday TelegraphPrior to the publication of Golden Lads, Anthony Bacon was viewed as a footnote in the history of his younger brother, Francis. A fascinating historical figure in his own right, Anthony Bacon was a contemporary of the brilliant band of gallants who gathered around the court of Elizabeth I, was closely connected to the Earl of Essex, and worked in France as a spy for Sir Francis Walsingham. While living in France he became acquainted with Henri IV and the essayist Michel de Montaigne, and it was there that Daphne du Maurier discovered a secret that, if disclosed during Bacon's lifetime, could have put an end to his political career. Du Maurier did much to uncover the truth behind matters that had long puzzled Elizabethan historians, while telling a strange and fascinating tale.

Golden Shadows, Flying Hooves: With A New Afterword
by George B. SchallerGeorge Schaller here shares with his reader the fascinating personal story behind his scientific discoveries that have so notably advanced our knowledge of the great African predators. In his new books, he allows us to participate moment by moment in his work and his experience on the Tanzanian plains as for three years he made his extraordinary of the habits, the hunting methods, the social systems, and the behavior—the lives from birth to death—of the lion, the wild dog, the cheetah, the leopard, and the hyena. We follow him afoot and in a Land-Rover, through the thickets, plains, and wooded grasslands of this wild, harsh landscape as he tranquilizes and then tags the great predators, as he gets to know their individual characteristics, as he investigates the vast array of species they depend upon for survival. We feel Schaller’s exaltation in the pure sensual motions of a lion stalking its prey, watch with him as a small furry mouse defends itself valiantly against a pack of wild dogs, as an Egyptian vulture breaks an ostrich eggs with a stone . . . We come to know the various postures of the animals in the hunt, what their territorial range is, how they behave with one another, how they raise their young . . . We are there as Schaller hangs a tiny radio transmitter around the neck of an old lion—the beeps will enable him to track the animal by night as well as day. We observe the businesslike gatherings of wild dogs, the blinding speed and elegant graces of a coursing cheetah, the soft-footed stalk of the hunting leopard, the tension that ripples though a herd id gazelle when they sense an approaching predator. We go back in times, through two million years, while Schaller and his colleagues attempt to simulate the hunting behavior of that pre-human, the hominid Australopithecus, scrabbling and scavenging for food, developing, in the process of their experiment, an incredible sensitivity to the sounds of zebra, giraffe, hyena, and the low, purposeful flight of a vulture—any sign of a possible meal, shelter, enemy. And, throughout, we feel Schaller’s commitment, his strong emotional kinship with the animals he studies and with the wild landscape where he and his family created a full life for themselves far from the accouterments of modern civilizations. With the gift of expressive narrative that distinguished his famous international bestseller, The Year of the Gorilla, Schaller makes us know close-up not only the teeming life of the plains and the great human adventure he lived but also the inspired improvisation, the tirelessness, the flights of imaginations that, as much as meticulous fact-finding, are an organic part of the original scientific investigation.
The Golden Spruce: A True Story of Myth, Madness and Greed
by John VaillantNATIONAL BESTSELLER • WINNER OF THE GOVERNOR GENERAL'S LITERARY AWARD FOR NON-FICTION • WINNER OF THE WRITERS&’ TRUST NON-FICTION PRIZE&“Absolutely spellbinding.&” —The New York TimesThe environmental true-crime story of a glorious natural wonder, the man who destroyed it, and the fascinating, troubling context in which this act took place. FEATURING A NEW AFTERWORD BY THE AUTHOROn a winter night in 1997, a British Columbia timber scout named Grant Hadwin committed an act of shocking violence in the mythic Queen Charlotte Islands. His victim was legendary: a unique 300-year-old Sitka spruce tree, fifty metres tall and covered with luminous golden needles. In a bizarre environmental protest, Hadwin attacked the tree with a chainsaw. Two days later, it fell, horrifying an entire community. Not only was the golden spruce a scientific marvel and a tourist attraction, it was sacred to the Haida people and beloved by local loggers. Shortly after confessing to the crime, Hadwin disappeared under suspicious circumstances and is missing to this day. As John Vaillant deftly braids together the strands of this thrilling mystery, he brings to life the ancient beauty of the coastal wilderness, the historical collision of Europeans and the Haida, and the harrowing world of logging—the most dangerous land-based job in North America.
Golden-winged Warbler Ecology, Conservation, and Habitat Management (Studies in Avian Biology)
by Henry M. Streby, David E. Andersen and David A. BuehlerGolden-winged Warblers (Vermivora chrysoptera) are migratory songbirds that breed in temperate North America, primarily in the Great Lakes region with remnant populations throughout the Appalachian Mountains, and winter in Central and northern South America. Their breeding range has contracted dramatically in the Appalachian Mountains and many populations have dramatically declined, likely due to habitat loss, competition and interbreeding with Blue-winged Warblers (Vermivora pinus), andglobal climate change.. As a result of population declines in much of the eastern portion of their breeding range, Golden-winged Warblers are listed as endangered or threatened in 10 U.S. states and in Canada and have been petitioned for protection under the U.S. Endangered Species Act. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series compiles extensive, current research on Golden-winged Warblers and summarizes what is known and identifies many remaining unknowns, providing a wealth of peer-reviewed science on which future research and listing decisions can be based.
Golden Years of Australian Radio Astronomy: An Illustrated History (Historical & Cultural Astronomy)
by Wayne Orchiston Peter Robertson Woodruff T. Sullivan IIIThe evolution of Australian radio astronomy from 1945 to 1960 has been studied in detail by numerous historians of science in recent years. This Open Access book is the first to present an overview of this remarkable chapter in Australian science. The book begins in the post-war period, as the Radiophysics Laboratory in Sydney switched from secret wartime research on radar to peacetime applications of this new technology. Next follows the detection of radio waves from space and the ensuing transformation of this fledgling science into the dominant research program at the Radiophysics Lab. Drawing from this history, the book shows how by 1960 the Radiophysics Lab had become the largest and most successful radio astronomy group in the world. The final chapter presents an overview of Australian radio astronomy from 1960 to the present day, as Australia prepares to co-host the multi-national, multi-billion-dollar Square Kilometre Array.Nearly 300 high-quality images complement the text, drawn from a wide range of sources including the extensive collection held by the CSIRO Radio Astronomy Image Archive. The book will be an essential reference for readers interested in the scientific and cultural development of radio astronomy.This book is published open access under a CC BY 4.0 license.
Goldfish and Other Carp (World Book's Animals of the World)
by Al SmuskiewiczIntroduces the common goldfish, offers a history, discusses related species of fish, and explains how to care for a goldfish.
Goldfish Development and Evolution
by Kinya G. OtaThis book explains how the beautiful goldfish body develops from a single fertilized egg and how this developmental process was changed during the process of domestication. The contents can be categorized as follows: i) numerous high-quality live photo images of embryonic and larval stage goldfish, ii) detailed descriptions of skeletogenesis with fluorescent microscopic and histological images, iii) the most advanced interpretation of the relationship between artificial selection and developmental processes, iv) future perspectives of the application of the genome editing techniques for the ornamental goldfish breeding, and v) methodological descriptions for goldfish developmental biology. Goldfish is a popular ornamental domesticated fish species, and its highly diverged morphological features and color variations attract fanciers. The goldfish has been spread all over the world by breeders, and this fish has also been employed as an experimental organism by researchers in the field of life science. However, so far, no available scientific books provide a detailed description of the embryogenesis and morphogenesis of this animal. Compared with the number of published fancier books, the number of books on goldfish biology is very few. This publication will be useful not only for the research community particularly in the fields of developmental biology, evolutionary biology, zoology, aquaculture, fishery science, and related areas but also for enthusiastic goldfish fanciers and breeders.

The Goldilocks Enigma: Why Is the Universe Just Right for Life?
by Paul DaviesPeople have long gazed in wonder at the universe and asked, Why are we here? Until recently, the answer has been the province of priests and philosophers, but now scientists are starting to weigh in with ideas that are both surprising and deeply controversial. In his new book, physicist Paul Davies shows how recent scientific discoveries point to a perplexing fact: many basic features of the physical universe-- from the speed of light to the most humble carbon atom-- seem tailor-made to produce life. A radical new theory says it's because our universe is just one of an infinite number of universes, each one slightly different. Our universe is bio-friendly by accident; we just happened to win the cosmic jackpot. While this multiverse theory is compelling, it has bizarre implications, from infinite copies of each of us to Matrix-like simulated universes. Davies believes there's a more satisfying solution to the question of existence: the observations we make today could help shape the nature of reality in the remote past. If this is true, then life and, ultimately, consciousness aren't just incidental byproducts of nature, but central players in the formation of the universe.
