Download or read book The Soil Resource written by Hans Jenny and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: change is simply described by the rate of income and rate of loss. Our home's energy budget, our firm's inventory, our nation's debt, and humanity's numbers all have accounts that change at rates that are equal to the inputs minus the outputs. Jenny's "system view" of the soil was carried into the fertile fields of Midwestern American prairies from the laboratories of Switzerland in the late 1920s. Jenny's rate equations provided the other paradigm or world view that, I recall, brought us to the threshold of systems ecology as it later evolved in the second half of the twentieth century. As if world renown in the specialties of pedology and soil chemistry were not enough for one lifetime, excerpts below remind us that Hans Jenny has also been a perceptive outdoor field ecologist since his early Alpine expeditions with Braun Blanquet in the mid 1920s. Jenny's ecosystem studies in the pygmy forest, a further classic example of a soil-plant system "run down" over hundreds of thousands of years since its origin, continue to occupy some of the vigorous retirement time near his farm in Mendocino County. But each specific, quantitative case study, and each research area conserved (with additional hard work) for further study by future generations, fits into Jenny's coherent world view. It is that view, and its legacies of discovery and of tangible landscape preserves, which we are privileged to share with their originator in this volume.
Download or read book The Encyclopedia of Aerodynamics written by Frank Hitchens and published by Andrews UK Limited. This book was released on 2015-11-25 with total page 877 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Aerodynamics was written for pilots at all levels from private pilot to airline pilot, military pilots and students of aerodynamics as a complete reference manual to aerodynamic terminology. General aerodynamic text books for pilots are relatively limited in their scope while aerodynamic text books for engineering students involve complex calculus. The references in this book, The Encyclopedia of Aerodynamics, are clearly described and only basic algebra is used in a few references but is completely devoid of any calculus - an advantage to many readers. Over 1400 references are included with alternative terms used where appropriate and cross-referenced throughout. The text is illustrated with 178 photographs and 96 diagrams. The Encyclopedia of Aerodynamics is an ideal aerodynamic reference manual for any pilot's bookshelf.
Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

Available in PDF, EPUB and Kindle. Book excerpt: In 2002 the 100th anniversary of the publication on "Culturversuche mit isolierten Pflanzenzellen" by Gottlieb Haberlandt was celebrated. Haberlandt ́s vision of the totipotency of plant cells represents the actual beginning of tissue culture. This book pays homage to a great Austrian scientist and the further development of his ideas. The first part of the book contains a facsimile of the original paper which is a true artistic masterpiece and its first translation into English from 1969. The second and third parts describe Haberlandt ́s life and work and early historical aspects of the development of plant tissue culture. The fourth part of the book contains an overview of important topics of plant tissue culture with the most promising areas of application to date and an outlook into the future. Areas range from micropropagation, production of pharmaceutically interesting compounds, plant breeding, genetic engineering of crop plants, including trees, and cryopreservation of valuable germplasm.

Download or read book Global Mission written by Henry Harley Arnold and published by Plunkett Lake Press. This book was released on 2023-07-06 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global Mission is General “Hap” Arnold’s personal story of his life and military career and a history of American military aviation with particular emphasis on World War II. “For twenty years prior to World War II General Arnold was a tireless and effective evangelist for American air power. No other foresaw more clearly than he the revolutionary impact of the airplane upon the methods and conduct of war. Hap Arnold performed still another public duty in recording for us the results and the conclusions of his lifetime experiences. Whatever he has to say about air power deserves the close attention of all his fellow citizens.” — General Dwight D. Eisenhower, US Army “The compellingly interesting autobiography of a great soldier-statesman and one of the finest presentations I have ever seen of the history of American military aviation.” — Lieutenant General James H. Doolittle, US Air Force “[T]his book is more than the chronicle of a flier’s life; it is in a sense a saga of United States air power, and particularly a top-level picture of the United States Army Air Force in World War II... Global Mission will take an important place in the growing library of war books... a delightful book; it brings out so strongly the lovable personality of “Hap” Arnold. It is an important book... these reminiscences are a monument to him.” — Hanson W. Baldwin, The New York Times “[An] interesting and important book” — Robert Gale Woolbert, Foreign Affairs “There are many groups of people who will profit by a careful reading of Global Mission. As General Bradley well said in a recent letter to me, ‘It is “must” reading for the young military men of today who will have to be the Marshalls and Arnolds and Kings in any future emergency.’ The thinking people of the United States will make wiser decisions in the selection of their leaders, both military and civil, if they have read Global Mission. They will understand more clearly the frightful errors which have been made in the past and their cost in blood and treasure... Any who are tempted to be pacifists or isolationists in the future had better read Global Mission to learn the implications which can flow from false doctrines. The historian who has the difficult job of painting the true picture of the Second World War needs to read Global Mission for background. Here alone will he find some of the missing pieces in his puzzle... by any yardstick, [Global Mission] is worthy reading for any American.” — Lieutenant General Ira C. Eaker, USAF (Ret.), Air University Quarterly Review “[General Arnold’s] book is a very important contribution to the history of the Second World War; one reads it with passionate interest from start to finish. It is written in a lively way and also with that frankness, that outspokenness, which always surprises French people from the pen of such a high authority. It is also extremely revealing about the American character.” — René Jouan, Revue d’histoire de la Deuxième Guerre mondiale “[This] book will be of enduring value.” — Ordnance
