Magnesium Deficiency in Forest Ecosystems
ISBN: 9789401062725 / Angielski / Miękka / 2012 / 362 str. Termin realizacji zamówienia: ok. 20 dni roboczych. R. F. HUTTL AND W. SCHAAF Brandenburg Technical University Cottbus, Chair of Soil Protection and Recultivation, P.O. Box 10 13 44, 03013 Cottbus, Germany The health status of forest trees and stands is determined by numerous site factors such as chemical, physical, and biological soil factors, water supply, climate, weather conditions, management history as well as atmospheric deposition impacts. In this context, the nutrient supply is an important evaluation parameter. Forest trees well supplied with nutrients are more resistant to stresses that affect the forest ecosystem than other trees....

Introduction to the Theory of Toeplitz Operators with Infinite Index
ISBN: 9783764367282 / Angielski / Twarda / 2002 / 300 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This book is devoted to Toeplitz and singular integral operators with symbols that have discontinuities of the oscillating type. Criteria for the normal solvability of such operators are established and several methods for describing the kernel and image spaces of the operators are presented. The approach is based on the idea of modelling discontinuities with an "infinite index" by appropriate inner functions, especially by infinite Blaschke products. The corresponding techniques have been elaborated by the authors during the last two decades, and they are applicable to both symbols with...

Magnesium Deficiency in Forest Ecosystems
ISBN: 9780792342205 / Angielski / Twarda / 1997 / 362 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The importance of magnesium in the element cycling of forest ecosystems has only been fully recognized since the widespread symptoms of forest magnesium deficiency were identified to be a major component in the damage phenomena. The intensive research during the last 15 years revealed not only details on the role of magnesium as a nutrient in forest ecosystems, but led also to a more comprehensive understanding of these ecosystems themselves and their functioning.
