Book Description
Bright gamma-ray flares observed from sources far beyond our Milky Way Galaxy are best explained if enormous amounts of energy are liberated by black holes. The highest- energy particles in nature--the ultra-high-energy cosmic rays--cannot be confined by the Milky Way's magnetic field, and must originate from sources outside our Galaxy. Understanding these energetic radiations requires an extensive theoretical framework involving the radiation physics and strong-field gravity of black holes. In High Energy Radiation from Black Holes, Charles Dermer and Govind Menon present a systematic exposition of black-hole astrophysics and general relativity in order to understand how gamma rays, cosmic rays, and neutrinos are produced by black holes. Beginning with Einstein's special and general theories of relativity, the authors give a detailed mathematical description of fundamental astrophysical radiation processes, including Compton scattering of electrons and photons, synchrotron radiation of particles in magnetic fields, photohadronic interactions of cosmic rays with photons, gamma-ray attenuation, Fermi acceleration, and the Blandford-Znajek mechanism for energy extraction from rotating black holes. The book provides a basis for graduate students and researchers in the field to interpret the latest results from high-energy observatories, and helps resolve whether energy released by rotating black holes powers the highest-energy radiations in nature. The wide range of detail will make High Energy Radiation from Black Holes a standard reference for black-hole research.

Book Description
This book presents the applications of high-energy beam radiation for synthesis and processing of polymeric materials. It addresses fundamental nature of high energy i.e., ionizing radiations and interaction with monomers and polymers leading to a wide variety of products such as tyres, textiles, shape memory polymers, polymers for aviation and space applications, polymeric biomaterials and natural rubber latex. It discusses general principles and techniques of preparation of polymeric materials including polymer blends, composites and nanocomposites. It also includes the topic of radiation-assisted recycling of polymers through breaking of covalent bonds. This book will be useful for students, researchers and professionals in the areas of polymers science and technology, radiation technology, electron beam technology, gamma radiation technology, advanced materials technology, biomaterials technology, nanotechnology, membrane science technology and environmental science.

Book Description
This book describes how the effects of nature's own nuclear reactors have shaped the Earth, the Solar System, the Universe, and the history of life as we know it. It focuses on observed effects that are poorly explained by our standard theories, identifies certain errors in those theories, and shows how these effects are caused by natural nuclear fission reactors. The theory of Plate Tectonics is wrong, and it is shown that expansion of the Earth causes continental drift. A physically reasonable mechanism is proposed for expansion and observational data are presented to show that this occurs. Evolution is explained as punctuated equilibrium, with mutations caused by abrupt surges of radiation, and related life forms that have been interpreted as seperate species are actually the result of radiation injury. This view is particularly effective as applied to humans. The ability of the dinosaurs to live so large is explained by use of Earth Expansion and a more massive atmosphere to provide buoyancy and effective transpiration of oxygen. These effects also explain how pterodactyls and ancient birds could fly. Expansion induced by impacts at the end of the Cretaceous caused the atmosphere to thin and the dinosaurs collapsed. Analysis of geological and biological data supports this. The astronomical distance scale is shown to be wrong, based on the misconception that trigonometric parallax is an absolute measurement. It isn't, and the method is led astray by the overwhelming number of asteroidal fragments masquerading as stars. The measurements of an expanding Universe are shown to be in error, and an expanding Universe is not needed by an alternative interpretation of Einstein's equations. This interpretation is based on the equal creation of matter and antimatter, which is known to occur. Spiral galaxies are not vast Island Universes of stars as we have thought, but are shown to be the strewn fields of debris from the nuclear fission detonation of distant planets.The Universe is not made up of 96% Dark Matter and Dark Energy, but is instead very ordinary. Abundant evidence and references provide support for all these interpretations. This book opens new opportunities for research by correcting several fundamental errors in our concepts of the Earth, Life, and the Universe.

Book Description
Newly updated, Botany: An Introduction to Plant Biology, Fourth Edition provides an current, thorough overview of the fundamentals of botany. The topics and chapters are organized in a sequence that is easy to follow, beginning with the most familiar -- structure -- and proceeding to the less familiar -- metabolism -- then finishing with those topics that are probably the least familiar to most beginning students -- genetics, evolution, the diversity of organisms, and ecology. Important Notice: The digital edition of this book is missing some of the images or content found in the physical edition.
