Найти книгу: "Danny Dunn and the Fossil Cave"

Danny and his friend Joe Pearson discover the entrance to a cave in the woods near their home. Professor Bulfinch has just invented a portable x-ray machine, and the Professor, along with his geologist friend Dr. Tresselt, sees an opportunity to use the device inside the cave. The two adults, along with Danny, Joe, and Irene, enter the cave on an expedition. They make an astonishing discovery, but they encounter a significant problem which prevents them from leaving the cave…<P> Danny Dunn and the Fossil Cave is the sixth novel in the Danny Dunn series of juvenile science fiction/adventure books written by Raymond Abrashkin and Jay Williams.

Clearly lays out the issues related to plastics' effects on the environment, while also serving as a practical, non-academic guide for making sustainability decisions about plastics recycling and the newest bio-based plastics Company managers, product developers, policy makers, environmental researchers, and plastics industry engineers are under increasing pressure to find ways of minimizing the environmental footprint of plastic products. This accessible book is designed to help readers understand the life-cycle impacts of various plastics, clarifying the technical research and practical arguments to show when bio-based and recycled plastics might be useful options for reducing the overall energy consumption, greenhouse gas emissions, and waste associated with traditional plastics. Plastics and Sustainability compares traditional fossil fuel-based plastics with bio-based plastics in terms of properties, environmental impacts, and costs – indicating what the most effective approaches could be for using recycled, biodegradable, or various bio-based materials. The book makes objective comparisons between bioplastics and all commonly used plastics, focusing on how they affect production economics, product requirements, and retailer and consumer needs. It incorporates research concerning life-cycle assessment, production techniques, and commercial applications, and presents «green» guidelines about product design, recycling, processing efficiency, and material selection. The book also reports on recent industry developments and commercial trends in an effort to synthesize conclusions that are necessary for finding the right balance between bio-based and fossil-fuel based plastic products.

Prehistoric life is the archive of evolution preserved in the fossil record. This book focuses on the meaning and significance of that archive and is designed for introductory college science students, including non-science majors, enrolled in survey courses emphasizing paleontology, geology and biology. From the origins of animals to the evolution of rap music, from ancient mass extinctions to the current biodiversity crisis, and from the Snowball Earth to present day climate change this book covers it, with an eye towards showing how past life on Earth puts the modern world into its proper context. The history of life and the patterns and processes of evolution are especially emphasized, as are the interconnections between our planet, its climate system, and its varied life forms. The book does not just describe the history of life, but uses actual examples from life’s history to illustrate important concepts and theories.

The book discusses the theoretical path to decoding the information gathered from observations of old stellar systems. It focuses on old stellar systems because these are the fossil record of galaxy formation and provide invaluable information ont he evolution of cosmic structures and the universe as a whole. The aim is to present results obtained in the past few years for theoretical developments in low mass star research and in advances in our knowledge of the evolution of old stellar systems. A particularly representative case is the recent discovery of multiple stellar populations in galactic globular clusters that represents one of the hottest topics in stellar and galactic astrophysics and is discussed in detail. Santi Cassisi has authored about 270 scientific papers, 150 of them in peer-reviewed journals, and the title Evolution of Stars and Stellar Populations.

Fossils provide a powerful tool for the study of the nearly 4-billion-year history of life, and its role in the evolution of Earth systems. They also provide important data for evolutionary studies, and contribute to our understanding of the extinction of organisms and the origins of modern biodiversity. Fossils At A Glance is written for students taking an introductory level course in paleontology. Short chapters introduce the main topics in the modern study of fossils. The most important fossil groups are discussed, from microfossils through invertebrates to vertebrates and plants, followed by a brief narrative of life on Earth. Diagrams are central to the book and allow the reader to see most of the important data “at a glance”. Each topic covers two pages and provides a self-contained suite of information or a starting point for future study. This second edition has been thoroughly revised and brought up to date. It includes new line diagrams as well as photographs of selected fossils
