This book provides extensive and comprehensive knowledge to the researchers/academics who are working in the field of cesium contaminated sites, and the impact on plants. This book is also helpful for graduate and undergraduate students who are specializing in radioecology or safe disposal of radioactive waste, remediation of legacies and the impact on the environment. Radiocesium (137Cs and 134Cs) was released into the environment as a result of nuclear weapons testing in 1950s and 1960s (~1x1018 Bq), and later due to the Chernobyl accident in 1986 (8.5x1016 Bq) and Fukushima Daiichi Nuclear Power Plant in 2011 (~1x1017 Bq). 137Cs is still of relevance due to its half-life of 30 years. The study of radioisotope 137Cs is important, as production and emission rates are high compared to other radioisotopes, due to high fission yield and high volatility. This book contains original work and reviews on how cesium is released into the environment on translocation from soil to plants and further on to animals and into the human food chain. Separate chapters focus on the effective half-life of cesium in plants and on how different cultivars are responding in accumulation of cesium. Other key chapters focus on cesium impact on single cells to higher plants and also on remediation measures as well as on basic mechanism used for remedial options and analysis of transfer factors. The book rounds off by contributions on cesium uptake and translocation and its toxicity in plants after the Chernobyl and Fukushima accidents.

This book gives an overview of research on graphs associated with commutative rings. The study of the connections between algebraic structures and certain graphs, especially finite groups and their Cayley graphs, is a classical subject which has attracted a lot of interest. More recently, attention has focused on graphs constructed from commutative rings, a field of study which has generated an extensive amount of research over the last three decades. The aim of this text is to consolidate this large body of work into a single volume, with the intention of encouraging interdisciplinary research between algebraists and graph theorists, using the tools of one subject to solve the problems of the other. The topics covered include the graphical and topological properties of zero-divisor graphs, total graphs and their transformations, and other graphs associated with rings. The book will be of interest to researchers in commutative algebra and graph theory and anyone interested in learning about the connections between these two subjects.

The Monteverde Cloud Forest Reserve has captured the worldwide attention of biologists, conservationists, and ecologists and has been the setting for extensive investigation over the past 30 years. Roughly 40,000 ecotourists visit the Cloud Forest each year, and it is often considered the archetypal high-altitude rain forest.This volume brings together some of the most prominent researchers of the region to provide a broad introduction to the biology of the Monteverde, and cloud forests in general. Collecting and synthesizing vital information about the ecosystem and its biota, the book also examines the positive and negative effects of human activity on both the forest and the surrounding communities. Ecologists, tropical biologists, and natural historians will find this volume an indispensable resource, as will all those who are fascinated by the magnificent wonders of the tropical forests.

Volume IV deals with the 'Middle Ages'. It starts with the expansion of Islam and closes with the discovery of the New World. Various events during this period led to a significant expansion in communications: the rapid spread of Islam and of Gengis Khan's Mongol Empire, as well as the Crusades and the development of trans-Saharan and maritime routes around Africa to the Indian Ocean, leading to multiplied exchanges between the peoples and cultures of Africa, Asia and Europe.

While the state of California remains one of the most striking and varied landscapes in the world, it has experienced monumental changes since European settlers first set foot there. The past two centuries have witnessed an ongoing struggle between environment and economy, nature and humanity that has left an indelible mark on the region. Green Versus Gold provides a compelling look at California's environmental history from its Native American past to conflicts and movements of recent decades. Acclaimed environmental historian Carolyn Merchant has brought together a vast storehouse of primary sources and interpretive essays to create a comprehensive picture of the history of ecological and human interactions in one of the nation's most diverse and resource-rich states. For each chapter, Merchant has selected original documents that give readers an eyewitness account of specific environments and periods, along with essays from leading historians, geographers, scientists, and other experts that provide context and analysis for the documents. In addition, she presents a list of further readings of both primary and secondary sources. Among other topics, chapters examine: California's natural environment and Native American lands the Spanish and Russian frontiers environmental impacts of the gold rush the transformation of forests and rangelands agriculture and irrigation cities and urban issues the rise of environmental science and contemporary environmental movement. Merchant's informed and well-chosen selections present a unique view of decades of environmental change and controversy. Historians, educators, environmentalists, writers, students, scientists, policy makers, and others will find the book an enlightening and important contribution to the debate over our nation's environmental history.
