Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to review all the fields of equatorial electrojet phenomena and their relevant theories in one volume. In certain relevant sections, the book discusses both the equatorial electrojet and the world-wide parts of the Sq current systems. Onwumwchili is an internationally known and highly respected expert in the equatorial electrojet field- a brand of geomagnetism.
Download or read book Spores of the Pteridophyta written by Alice F. Tryon and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book constitutes a unique, encyclopedic reference work that systematizes and categorizes for the first time in such comprehensive fashion all known fern spores. The dominant feature of the work are the over 350 plates of electron micrographs showing the morphological characteristics of typical representatives of each spore type. The purpose of the book is to provide a complete survey of the available data on the fine structure and composition, development, and evolu- tionary significance of different types of spore walls, which have proven resistant to fossilization throughout geological ages. The classification system developed by the authors as the result of many years of research will be a point of reference, if not "the" systematic basis, for all future publication on the subject. The book will be of great interest to all botanists and evolutionary biologists working with spores and/or ferns, but it will also be of major importance to paleobotanists, palynologists, stratigraphers, and exploration geologists, since the focus of this treatise is on spores as highly adapted and longlived reproductive forms.

Download or read book Following the Sun with Kepler s Model written by Glenn Meyers and published by Glenn Meyers. This book was released on 2024-02-28 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This short e-book is written for someone who knows a little math, and wants to understand how our Sun moves across the horizon throughout the year. It shows how to calculate the times of the sunrise, sunset and solar noon. It also explains the mathematics underlying the construction of sundials, and shows how to use a sundial to calculate the correct time as you see it on your watch. Starting with Kepler's first two laws of planetary motion, the e-book guides the reader step by step through the calculations described above. It assumes that the reader is comfortable with trigonometry, polar coordinates and introductory calculus.

Download or read book Numerical Model of the Equatorial Electrojet written by Arthur D. Richmond and published by . This book was released on 1972 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer program which calculates electron and ion densities, ionospheric conductivities, electric fields and currents, and magnetic variations in regions near the magnetic equator is described in detail. It is also explained how this numerical model can be used to deduce F-region vertical plasma drifts in the equatorial ionosphere from observed magnetic variations at ground level. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A joint United States - Brazil experiment was conducted near the geomagnetic equator to confirm the theoretically predicted strong dependence of the ionospheric reflection properties on the azimuthal direction of wave propagation. Skywave delays, reflection coefficients, and polarization ellipses were measured at different frequencies, ranges, and azimuths. The results were compared with full-wave computer calculations for several ionospheric models. A series of high resolution waveforms showing the sunrise transition from night- to daytime conditions is included.
