This book presents an overview of the chemistry, geology, toxicology and environmental impacts of arsenic, presenting information on relatively common arsenic minerals and their key properties. In addition, it includes discussions on the environmental impacts of the release of arsenic from mining and coal combustion. Although the environmental regulations of different nations vary and change over time, prominent International, North American, and European guidelines and regulations on arsenic will be reviewed. Includes information on recent environmental catastrophes (e.g. Bangladesh and China) A thorough discussion of the arsenic cycle, including the cosmological origin of arsenic Includes Appendices providing extensive glossary and measurement conversion tables
Ice Caves synthesizes the latest research on ice caves from around the world, bringing to light important information that was heretofore buried in various reports, journals, and archives largely outside the public view. Ice caves have become an increasingly important target for the scientific community in the past decade, as the paleoclimatic information they host offers invaluable information about both present-day and past climate conditions. Ice caves are caves that host perennial ice accumulations and are the least studied members of the cryosphere. They occur in places where peculiar cave morphology and climatic conditions combine to allow for ice to form and persist in otherwise adverse parts of the planet. The book is an informative reference for scientists interested in ice cave studies, climate scientists, geographers, glaciologists, microbiologists, and permafrost and karst scientists. - Covers various aspects of ice occurrence in caves, including cave climate, ice genesis and dynamics, and cave fauna - Features an overview of the paleoclimatic significance of ice caves - Includes over 100 color images of ice caves around the world
Tracers in Hydrology and Water Research is a comprehensive overview of the application of natural and artificial tracers in hydrology and environmental research. Taking a unique approach by providing the reader with a systematic and state of the art description of natural and artificial tracers, the book also covers key analytical techniques and applications, and modern tracer methods in the context of systematic hydrology. Tracers have become a primary tool for process investigation, qualitative and quantitative system analysis and integrated resource management. This book will outline the fundamentals of the subject, and examine the latest research findings, clearly showing the entire proc...
Anthony Fiorillo has been exploring the Arctic since 1998. For him, like many others, the Arctic holds the romance of uncharted territory, extreme conditions, and the inevitable epic challenges that arise. For Fiorillo, however, the Arctic also holds the secrets of the history of life on Earth, and its fossils bring him back field season after field season in pursuit of improving human understanding of ancient history. His studies of the rocks and fossils of the Arctic shed light on a world that once was, and provide insight into what might be.
The first complete dinosaur skeleton, that of an Iguanodon, was discovered in a coal mine in Bernissart in 1878. This book examines the Bernissart locality, the methodology of the excavation, and the genus Iguanodon.
Progress in the field of plant cell and tissue culture has made this area of research one of the most dynamic and promising not only in plant physiology, cell biology and genetics but also in agriculture, forestry, horticulture and industry. Studies with plant cell cultures clearly have bearing upon a variety of problems as yet unsolved in basic and applied research. This was the compelling reason for assembling such a comprehensive source of information to stimulate students, teachers, and research workers. This book comprises 34 articles on regeneration of plants, vegetative propagation and cloning; haploids; cytology, cytogenetics and plant breeding; protoplasts, somatic hybridization and genetic engineering; plant pathology; secondary products and a chapter on isoenzymes, radiobiology, and cryobiology of plant cells. Particular attention has been paid to modern , fast-growing and fascinating disciplines - e.g. the induction of haploids, somatic hybridization and genetic manipulation by protoplast culture, which possess an enormous potential for plant improvement.
