Download or read book On Formulating a Simple D Region Model written by William Swider and published by . This book was released on 1987 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report focuses on a body of work that suggests that the effective recombination coefficients in the daytime D-Region are fairly invariant and thus lead to a rather simple solution for the electron concentrations. In addition, a quadratic expression is available for the estimation of electron concentrations at night. The ionization production rate q must be known and incorporated into the chemistry of the D region to determine electron concentrations (e) as a function of altitude. There is some D region research which supports a simple way to determine (e) once q is known. Thus, the daytime effective recombination coefficient, Psi, appears to be relatively insensitive to q and can provide for the determination of (e), (e) = sq rt(q/Psi) under steady-state conditions. For steady-state conditions at night, an equation exists which yields (e) with reasonable accuracy. Keywords: D Region; Ionosphere; Mesosphere. (JHD).

Available in PDF, EPUB and Kindle. Book excerpt: Positive ion composition measurements obtained with rocket-borne mass spectrometers in the lower ionosphere are presented. The current situation regarding the water cluster ions in the D region is considered. Evidence is given in favor of an ambient instead of a contamination origin for the water cluster ions, although the exact processes for the formation of these ions in the atmosphere are still not definitely established. A theory is discussed whereby water cluster ions may be created through the ionization of small water conglomerates, which are assumed both to be present in the mesosphere and to have very low ionization thresholds.

Available in PDF, EPUB and Kindle. Book excerpt: A computer program has been developed for the nighttime D-region under disturbed steady-state conditions. The program provides for the determination of the electron concentration, total negative ion concentration, and the individual positive ion concentrations as a function of altitude. Model results are computed and compared with nighttime data obtained by various experimentalists during the 2 to 5 November 1969 solar proton event.

This book was released on 1974 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: D-region ionization rates have been determined from satellite proton spectra as a function of altitude for forty-four instances during the period of 2 to 5 November 1969 Polar Cap Absorption Event. The ionization rates were calculated using least square fits to the satellite proton spectra in both energy and rigidity. The combined results provide ionization rates for the event as a function of universal time. (Author).
Download or read book Tourism Environment and Ecology in the Mediterranean Region written by Recep Efe and published by Cambridge Scholars Publishing. This book was released on 2014-09-26 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: As humans we have stewardship over the environment. Man’s dominion does not mean a license to abuse, spoil, squander or destroy. Future cultures will be able to reach their potential only if this generation remembers that sustainable land use is a combination of economics, ecology and social justice. Our ancestors survived due to an innate sense of “oneness” whereby they helped each other. For them everything was “holy”. Sustaining desired ecological, economic, and social conditions in the system is a big challenge, but not an impossible task. This book presents chapters by scientists from different disciplines from the Mediterranean Basin and its environs. It presents updated information and highlights the way forward for the fields of economy, environment and ecology, making this book a very useful source for people working in these different disciplines. Contributions have been prepared by experts in these respective fields. The book also brings to the fore important future tasks for these particular disciplines, and provides up-to-date references, tables and figures illustrating research findings. As such, this volume is a must-read for students, researchers and professionals in environmental sciences, ecology, forestry, geography and other related fields.

This book was released on 2000-11-11 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The present book is intended as a progress report on [the] synthetic approach to evolution as it applies to the plant kingdom." With this simple statement, G. Ledyard Stebbins formulated the objectives of Variation and Evolution in Plants, published in 1950, setting forth for plants what became known as the "synthetic theory of evolution" or "the modern synthesis." The pervading conceit of the book was the molding of Darwin's evolution by natural selection within the framework of rapidly advancing genetic knowledge. At the time, Variation and Evolution in Plants significantly extended the scope of the science of plants. Plants, with their unique genetic, physiological, and evolutionary features, had all but been left completely out of the synthesis until that point. Fifty years later, the National Academy of Sciences convened a colloquium to update the advances made by Stebbins. This collection of 17 papers marks the 50th anniversary of the publication of Stebbins' classic. Organized into five sections, the book covers: early evolution and the origin of cells, virus and bacterial models, protoctist models, population variation, and trends and patterns in plant evolution.
