The Chemistry And Literature Of Beryllium - PDF
نویسندگان: خلاصه: All normal compounds of beryllium which are soluble in water are strongly acid in reaction to litmus, dissolve notable quantities of their own hydroxide which increases in amount with the concentration of the solution, set free carbon dioxide from carbonates and attack certain metals. In short, they act in many respects like the acids themselves would act from which they are derived. In spite of these facts they show less hydrolysis, and consequent smaller concentration of hydrogen ions, at least in the case of the chloride, nitrate and sulphate, (iveys, 1899; 10 and Brunner, 1900; 1) when treated by the well-known method of sugar inversion, than the corresponding salts of iron and aluminum. By the same method of determination, the hydrogen ions are thrown back into the undissociated condition when but a small fraction of the beryllium hydroxide has been dissolved which the normal salt is capable of holding in solution, (Parsons, 1904; 10). The reasons for these phenomena are not at present understood. The sulphate has been recently studied with a view to a solution of this problem, (1907; 10) and it has been shown that the addition of beryllium hydroxide to a solution of the sulphate, raises the freezing point and diminishes the conductivity; that no beryllium enters into the formation of a complex anion and that while the hydroxide can be partially removed by dialysis if dialyzed into pure water, there is little evidence of a colloid being present. It has been suggested that we may have here a new instance of solution, wherein the solid, when once dissolved, acts as a true solvent for its own oxide or hydroxide, and there are some analogies which point strongly to this view, (1907; n).
Urban Transportation Planning in the United States: History, Policy, and Practice (3rd Edition) - PDF
نویسندگان: خلاصه: The development of U.S. urban transportation policy over the past 50 years illustrates the changing relationships among federal, state, and local governments. This comprehensive text examines the evolution of urban transportation planning from early developments in highway planning in the 1930s to today’s concerns over sustainable development, security, and pollution control. Focusing on major national events, the book discusses the influence of legislation, regulations, conferences, federal programs, and advances in planning procedures and technology. The book focuses in-depth at the most significant event in transportation planning--the Federal-Aid Highway Act of 1962; creating a federal mandate for a comprehensive urban transportation planning process carried out cooperatively by states and local governments with federal funding, this act was crucial in the spread of urban transportation.
When Blood and Bones Cry Out: Journeys Through the Soundscape of Healing and Reconciliation - Original PDF
نویسندگان: خلاصه: Around the world communities that have suffered the trauma of unspeakable violence--in Liberia, Somalia, West Africa, Columbia, and elsewhere--are struggling to recover and reconcile, searching for ways not just to survive but to heal. In When Blood and Bones Cry Out, John Paul Lederach, a pioneer of peace-building, and his daughter, Angela Jill Lederach, show how communities can recover and reconnect through the power of making music, creating metaphors, and telling their extraordinary stories of suffering and survival. Instead of relying on more common linear explanations of healing and reconciliation, the Lederachs demonstrate how healing is circular, dynamic, and continuing, even in the midst of ongoing violence. They explore the concept of "social healing," a profoundly important intermediary step between active warfare and reconciliation. Social healing focuses on the lived experience of those who have suffered protracted violence and their need to give voice to that experience, both individually and collectively. Giving voice, speaking the unspeakable, in words and sounds that echo throughout traumatized communities, can have enormous healing power. Indeed, the Lederachs stress the remarkable effects of sound and vibration through tales of Tibetan singing bowls, Van Morrison's transcendent lyrics, the voices of mothers in West Africa, and their own personal journeys. And they include inspiring stories of transformation: a mass women's protest movement in Liberia that forces leaders to keep negotiating until a peace agreement is signed; elders in Somalia who walk between warring clans year after year to encourage dialogue; former child soldiers who run drum workshops and grow gardens in refugee camps; and rape victims in Sierra Leone who express their pain in poetry. With equal measures of insight and compassion, When Blood and Bones Cry Out offers a promising new approach to healing traumatized communities.
