In the years since the book of Lozanskii and Firsov "The Theory of Spark"  was published, a number of experimental and theoretical studies in the physics of electric breakdown in gases were conducted. As a result of these studies, the concept of a wavelike nature of breakdown initiated by single high-voltage electric pulses or by a constant electric field was confirmed. Theoretical models in which the concept of breakdown in a constant external field was developed were first exposed in the above-named book in the chapter "Development of a streamer regarded as an ionization wave," written by Rodin and Starostin. This book treats the initial stage of electric breakdown as a wave proÂ cess. The wavelike nature of the phenomena under consideration is preÂ sented for streamers and sliding discharges, for electric breakdown developÂ ment in long discharge tubes as well as in gas-filled gaps. Chapter 1 gives a qualitative consideration of phenomena determinÂ ing the electric breakdown of gases. The experimental data and theoretical results are exposed and discussed with application to streamers, plane ionÂ ization waves, breakdown waves in long tubes, and propagation of sliding discharges. The subject of this chapter may be considered as an area of applications of different theoretical models, formulas, and estimates that are presented in other chapters of the book.
An excellent training manual and professional reference, "Fundamentals of Oil and Gas Accounting, 5th Edition", is packed with examples, diagrams, and appendices. The scope of this text is simply unmatched. The book has been completely updated to reflect the current issues facing oil and gas producers operating in both U.S. and international locations. Inside you'll find: a new chapter on asset retirement obligations and asset impairment; an added section on project, analysis and investment decision making; updated coverage of asset exchanges and fair value reporting requirements; thorough discussion of oil and gas pricing and marketing arrangements; and, updated examples and homework problems.
Mama says she has the best daughters in the world. The two women live near their motherRosa with her husband and children, Blanca by herself. They both have flourishing gardens. Rosa and Blanca are so generous and kind and thoughtfulwell, everyone, including Mama, ends up with too much corn, tomatoes, and red hot chiles! It's crazy! It's also Joe Hayes at his finest, telling one of those stories young kids love, full of mishaps, surprise endings, and happy mommas! In fact, one seven-year oldafter hearing Joe tell "Don't Say a Word, Mama!"came home and told her mother, "I heard a story today that I think changed my life!" That's a pretty fantastic endorsement!2014 Honor Book, Patterson Prize for Books for Young PeopleJoe Hayes has been enchanting listeners and readers alike for over thirty years. His books have received many awards including two Land of Enchantment Children's Book Awards and an Aesop Accolade Award. His books have also been on the Texas Bluebonnet Award Master List three times. "Ghost Fever" won the Texas Bluebonnet Award for 20062007.Esau Andrade Valencia comes from a family of folk artists. He is increasingly being recognized as a master artist in the tradition of Diego Rivera and Rufino Tamayo. His paintings are included in the collection of the Museum of Latin American Art in Long Beach, California, as well as in the Downey Museum of Art in Downey, California."
