The Rat Its History amp Destructive Character With Numerous Anecdotes By James Rodwell This book is one of the earliest published works dealing solely with the Rat, its history and natural history, and the numerous methods for its disposal. Its author states «I have studied the Nature, Fecundity, and Devastating Character of the Rat, and I have spared neither the time nor trouble in obtaining all the information within my power.» First published in London 1863, the original edition is an extremely rare item. Read Country Books has now re-published it in its entirety from the original text. Its 312 pages contain twenty nine detailed and entertaining chapters:– The Different Kinds of Rats, and their Natural History. – The Unreasonable Fear of Rats. – General Characteristics. – Tame Rats. – Rats Nests. – Dietetics of Rats. – Testimonies of Writers and Naturalists. – Predatory and Destructive Habits of Rats. – Thievish Propensities. – The Destruction and Extirpation of Rats. – Wonderful Tales of Rats. – Courage, Ferocity, and Cunning of Rats. – United Attacks of Rats. – Their Natural Weapons. – Articles Manufactured from Rat Skins. – Rats as Human Food. – Whistling Joe, the Hertfordshire Sermulot Hunter and Ratcatcher. – Miscellaneous Anecdotes. – Universal Prevalence and Destructive Habits. – Fecundity of Rats. – Vermin Killers and Rat Matches. – Sewer Rats and Ratcatchers of London. – Ratcatchers and Best Means. – How Farmers should Extirpate Their Vermin. – Natures Methods. – Ratcatching and Killing with Dogs. – Trapping, and the Various Kinds of Rat Traps. – Poisoning of Rats. – Phosphoric Poisons. – etc. A final lengthy chapter gives some profitable hints on the breeding, feeding, and management of poultry, more especially the Spanish Dorking. This comprehensive and unusual book will appeal to the naturalist, Sportsman, Gamekeeper, and Historian alike. Many of the earliest sporting books, particularly those dating back to the 1800s, are now extremely scarce and very expensive. Read Country Books are reprinting these classic works in affordable, high quality, modern editions. These editions are republished using the original text and artwork.

This book comprises the lectures of a two-semester course on quantum field theory, presented in a quite informal and personal manner. The course starts with relativistic one-particle systems, and develops the basics of quantum field theory with an analysis on the representations of the Poincaré group. Canonical quantization is carried out for scalar, fermion, Abelian and non-Abelian gauge theories. Covariant quantization of gauge theories is also carried out with a detailed description of the BRST symmetry. The Higgs phenomenon and the standard model of electroweak interactions are also developed systematically. Regularization and (BPHZ) renormalization of field theories as well as gauge theories are discussed in detail, leading to a derivation of the renormalization group equation. In addition, two chapters — one on the Dirac quantization of constrained systems and another on discrete symmetries — are included for completeness, although these are not covered in the two-semester course.This second edition includes two new chapters, one on Nielsen identities and the other on basics of global supersymmetry. It also includes two appendices, one on fermions in arbitrary dimensions and the other on gauge invariant potentials and the Fock-Schwinger gauge.<b>Contents:</b> <ul><li>Preface</li><li>Relativistic Equations</li><li>Solutions of the Dirac Equation</li><li>Properties of the Dirac Equation</li><li>Representations of Lorentz and Poincaré Groups</li><li>Free Klein–Gordon Field Theory</li><li>Self-Interacting Scalar Field Theory</li><li>Complex Scalar Field Theory</li><li>Dirac Field Theory</li><li>Maxwell Field Theory</li><li>Dirac Method for Constrained Systems</li><li>Discrete Symmetries</li><li>Yang–Mills Theory</li><li>BRST Invariance and Its Consequences</li><li>Higgs Phenomenon and the Standard Model</li><li>Regularization of Feynman Diagrams</li><li>Renormalization Theory</li><li>Renormalization Group and Equation</li><li>Nielsen Identities and Gauge Independence of Physical Parameters</li><li>Basics of Global Supersymmetry</li><li>Index</li></ul><br><b>Readership:</b> Graduate students and researchers in theoretical physics.

We are told we are living in the middle of a climate crisis of unprecedented proportions. As doomsday scenarios mount, hope collapses. Even as more and more people around the planet experience climate disaster as immediate and urgent, our imagination and programs for transformation lag. The disasters are already here, and the crises, longstanding, are ongoing. In Hope Against Hope , the Out of the Woods collective investigates the critical relation between climate change and capitalism and calls for the expansion of our conceptual toolbox to organize within and against ecological crisis characterized by deepening inequality, rising far-right movements, and—relatedly—more frequent and devastating disasters. While much of environmentalist and leftist discourse in this political moment remain oriented toward horizons that repeat and renew racist, anti-migrant, nationalist, and capitalist assumptions, Out of the Woods charts a revolutionary course adequate to our times. At the center of the renewed political orientation Hope Against Hope expounds is an abolitionist approach to border imperialism, reactionary ecology, and state violence that underpins many green solutions and modes of understanding nature. It reminds us of the frequent moments and movements of solidarity emerging in the ruins all around us. Their stunning conclusion to the disarray of politics in our seemingly end times is the urgency of creating what Out of the Woods calls “disaster communism”—the collective power to transform our future political horizons from the ruins and establish a climate future based in common life.

Over 85% of horse training problems are due to humans being unable to think like a horse The first book written for horsemen by a doctor of cognitive science Throughout the book there are «barn side» applications of brain science—it's not a text book! Readers will walk away knowing more about their own brains as well as their horses

What set our ancestors off on a separate evolutionary trajectory was the ability to flex their reproductive and social strategies in response to changing environmental conditions. Exploring new cross-disciplinary research that links this capacity to critical changes in the organization of the primate brain, Social DNA presents a new synthesis of ideas on human social origins – challenging models that trace our beginnings to traits shaped by ancient hunting economies, or to genetic platforms shared with contemporary apes.
