Author: Arboricultural Practices
Author: Lindsey PurcellPublisher: Waveland Press
ISBN: 1478653329
Category : Technology & Engineering
Languages : en
Pages : 378
Book Description
In our urban forests and designed landscapes, trees stand as the most important and resilient green elements. Arboricultural Practices by Lindsey Purcell is an essential guide for all green professionals—including arboricultural consultants, arborists, urban foresters, landscape architects, landscape contractors and tree owners and managers—offering comprehensive insights into aligning arboricultural practices with urban forestry initiatives and sustainability goals. Drawing from over 40 years of experience and an extensive body of work, Purcell shares practical knowledge and best practices for the industry, distilled from his career as a tree-care professional and educator. This textbook is especially tailored for instructors and students, covering a wide range of topics essential for the next generation of arborists and urban foresters. The book covers all aspects of arboriculture from the fundamentals of tree growth and development to essential management practices. It follows the tree from selection in the nursery to planting and aftercare through such routine practices as pruning, fertilization, support systems, and plant health care. Arboricultural Practices is a comprehensive resource for academic and professional applications.

Author: GrayAn Analytic Theory Of Multi-stream Electron Beams In Traveling Wave Tubes
Author: Alexander FigotinPublisher: World Scientific
ISBN: 9811209219
Category : Science
Languages : en
Pages : 499
Book Description
The Traveling Wave Tubes (TWT) is a powerful vacuum electronic device used to amplify radio-frequency (RF) signals as well as numerous applications such as radar, television and telephone satellite communications. This monograph is devoted to the author's original theoretical developments in the theory of a traveling wave tube (TWT).Most of the monograph is the author's original work on an analytical theory of TWTs. It is a constructive Lagrangian field theory of TWT in which the electron beam (e-beam) is represented by one-dimensional multi-stream electron flow and the guiding slow-wave structure is represented by possibly non-uniform multi-transmission line (MTL). The proposed analytic theory accounts for a number of electron plasma phenomena including space-charge effects such as electron-to-electron repulsion (debunching), convective instabilities, wave-particle interaction, amplifying waves and more. It allows, in particular, to (i) identify origins of the wave-particle interaction and the system convective instability (exponential growth); (ii) evaluate the energy transfer rate from the e-beam to the electromagnetic radiation; (iii) identify instability modal branches which under condition of sufficiently strong coupling between the e-beam and the MTL can cover ideally all frequencies.
