Selenium-based methods in synthetic chemistry have developed rapidly over the past years and are now offering highly useful tools for organic synthesis. Filling the gap for a comprehensive handbook and ready reference, this book covers all modern developments within the field, including biochemical aspects. The chemistry chapters are organized according to the different reactivities of various selenium compounds and reagents, with each chapter dealing with a special reaction type. Also includes a table with 77Se NMR shifts to aid in practical problems. From the Contents: * Electrophilic and Nucleophilic Selenium * Selenium Compounds in Radical Reactions * Selenium-Stabilized Carbanions * Selenium Compounds with Valency Higher than Two * Selenocarbonyls * Selenoxide Elimination and [2,3]-Sigmatropic Rearrangement * Selenium Compounds as Ligands and Catalysts * Biological and Biochemical Aspects of Selenium Compounds

At the height of the Vietnam War, thousands of Americans wrote moving letters to Dr. Benjamin Spock, America’s pediatrician and a high-profile opponent of the war. Personal and heartfelt, thoughtful and volatile, these missives from Middle America provide an intriguing glimpse into the conflicts that took place over the dinner table as people wrestled with this divisive war and with their consciences.Providing one of the first clear views of the home front during the war, Dear Dr. Spock collects the best of these letters and offers a window into the minds of ordinary Americans. They wrote to Spock because he was familiar, trustworthy, and controversial. His book Baby and Child Care was on the shelves of most homes, second only to the Bible in the number of copies sold. Starting in the 1960s, his activism in the antinuclear and antiwar movements drew mixed reactions from Americans—some puzzled, some supportive, some angry, and some desperate.Most of the letters come from what Richard Nixon called the “silent majority”—white, middleclass, law-abiding citizens who the president thought supported the war to contain Communism. In fact, the letters reveal a complexity of reasoning and feeling that moves far beyond the opinion polls at the time. One mother of young children struggles to imagine how Vietnamese women could endure after their village was napalmed, while another chastises Spock for the “dark shadow” he had cast on the country and pledges to instill love of country in her sons.What emerges is a portrait of articulate Americans struggling mightily to understand government policies in Vietnam and how those policies did or did not reflect their own sense of themselves and their country.

This is a true story where the main characters are feline. There are some humans too. It is a story of cat love and loss. It is also a story of two humans finding each other and of human love and bonding. My name is Don Weiser. I had three cats: Jones (who is all black with green eyes and is going on 21 years of age), Spock (who is an Abyssinian and is presently lost), and Sam (who is a huge orange tabby who was a stray). I lived in Albany, NY for 17 years and worked for the Department of Social Services. My wife Beth lives in North Carolina and had three cats: Smokey (who is a lovely lion like gray tabby with the largest head I have ever seen), Maggie (who was a solid black cat with gold eyes), and Rosy (who is also a solid black cat with gold eyes and who is Maggie&#39;s daughter). Beth and I are now married (8/90) and live in North Carolina with our six cats. Maggie is dead, Spock is lost, and Junior (the youngster cat who is a tabby) now lives with us. These are the main characters and the story is about how we all came to live together in North Carolina. I hope you find it interesting. It may make you cry, I hope it makes you laugh too.<br><br>My book is meant to help anyone whose pet is lost.
