The first volume devoted to anthropogenic effects on interactions between ants and flowering plants, considered major parts of terrestrial ecosystems.
This book provides new clues for understanding electrostatic charging in solids and liquids, resulting from the surge of research in this active area of science that is taking place since the 1990's but is still largely unknown to most researchers, lecturers and engineers. Written by a leading researcher in this field, this book describes the formation and properties of the Earth capacitor, the production of environmental electricity and its effect on natural and anthropic systems and examines many situations in which water may play a decisive role in electrostatic behavior. The authors present an informed critique of the long-held assumption that pure substances should be electroneutral. In this regard, the authors show that charge partition and accumulation is expected considering the electrochemical potential under non-zero electrostatic potential, which prevails at Earth surface. This book provides conceptual tools to guide the reader through the complexities and consequences of electrostatic phenomena while covering exciting current topics such as energy scavenging from the environment, electrostatic based green production, energy-saving processes, electrochemistry at the solid-gas interface, therapeutic electrostatic treatments, applications in sanitation and pest control and control of atmospheric electricity and its use in climate engineering.
For two hundred years the pessimists have dominated public discourse, insisting that things will soon be getting much worse. But in fact, life is getting better—and at an accelerating rate. Food availability, income, and life span are up; disease, child mortality, and violence are down all across the globe. Africa is following Asia out of poverty; the Internet, the mobile phone, and container shipping are enriching people's lives as never before. In his bold and bracing exploration into how human culture evolves positively through exchange and specialization, bestselling author Matt Ridley does more than describe how things are getting better. He explains why. An astute, refreshing, and revelatory work that covers the entire sweep of human history—from the Stone Age to the Internet—The Rational Optimist will change your way of thinking about the world for the better.
