A broad coverage of boron topics is provided. Structural elucidations and convenient routes to useful hydroboration reagents are presented as well as boron compounds used for medical purposes. Special attention is devoted to theoretical studies and calculations on small boron-hydrogen and boron-noble gas species including molecules like BH, which are rather favorite subjects of theoreticians for testing various methods of calculation.
The landscapes of North America, including eastern forests, have been shaped by humans for millennia, through fire, agriculture, hunting, and other means. But the arrival of Europeans on America’s eastern shores several centuries ago ushered in the rapid conversion of forests and woodlands to other land uses. By the twentieth century, it appeared that old-growth forests in the eastern United States were gone, replaced by cities, farms, transportation networks, and second-growth forests. Since that time, however, numerous remnants of eastern old growth have been discovered, meticulously mapped, and studied. Many of these ancient stands retain surprisingly robust complexity and vigor, and forest ecologists are eager to develop strategies for their restoration and for nurturing additional stands of old growth that will foster biological diversity, reduce impacts of climate change, and serve as benchmarks for how natural systems operate. Forest ecologists William Keeton and Andrew Barton bring together a volume that breaks new ground in our understanding of ecological systems and their importance for forest resilience in an age of rapid environmental change. This edited volume covers a broad geographic canvas, from eastern Canada and the Upper Great Lakes states to the deep South. It looks at a wide diversity of ecosystems, including spruce-fir, northern deciduous, southern Appalachian deciduous, southern swamp hardwoods, and longleaf pine. Chapters authored by leading old-growth experts examine topics of contemporary forest ecology including forest structure and dynamics, below-ground soil processes, biological diversity, differences between historical and modern forests, carbon and climate change mitigation, management of old growth, and more. This thoughtful treatise broadly communicates important new discoveries to scientists, land managers, and students and breathes fresh life into the hope for sensible, effective management of old-growth stands in eastern forests.
In 1864, amid headline-grabbing heresy trials, members of the British Association for the Advancement of Science were asked to sign a declaration affirming that science and scripture were in agreement. Many criticized the new test of orthodoxy; nine decided that collaborative action was required. The X Club tells their story. These six ambitious professionals and three wealthy amateurs—J. D. Hooker, T. H. Huxley, John Tyndall, John Lubbock, William Spottiswoode, Edward Frankland, George Busk, T. A. Hirst, and Herbert Spencer—wanted to guide the development of science and public opinion on issues where science impinged on daily life, religious belief, and politics. They formed a private dining club, which they named the X Club, to discuss and further their plans. As Ruth Barton shows, they had a clear objective: they wanted to promote “scientific habits of mind,” which they sought to do through lectures, journalism, and science education. They devoted enormous effort to the expansion of science education, with real, but mixed, success. For twenty years, the X Club was the most powerful network in Victorian science—the men succeeded each other in the presidency of the Royal Society for a dozen years. Barton’s group biography traces the roots of their success and the lasting effects of their championing of science against those who attempted to limit or control it, along the way shedding light on the social organization of science, the interactions of science and the state, and the places of science and scientific men in elite culture in the Victorian era.
The CRC Handbook of Solubility Parameters and Other Cohesion Parameters, Second Edition, which includes 17 new sections and 40 new data tables, incorporates information from a vast amount of material published over the last ten years. The volume is based on a bibliography of 2,900 reports, including 1,200 new citations. The detailed, careful construction of the handbook develops the concept of solubility parameters from empirical, thermodynamic, and molecular points of view and demonstrates their application to liquid, gas, solid, and polymer systems.
