About three years ago Catherine de Berg and I published a short article in Nature in which we attempted to explain why the chemistry of the atmosphere of the Earth is today so completely different from that of our two neighbor- ing planets, Mars and Venus.
Radiography, the use of penetrating radiation to produce shadow images of the internal structure of materials, has been with us since Roentgen made his discovery of x rays in 1895.
Soil science is perhaps one of the oldest practical sciences, having been of concern to man probably from the time he progressed from a strictly preda- tory life to one in which agriculture became important.
Within very recent time, when investigating the allowing one to explain possible transformations according to variations in different characteristics physicochemical conditions under which sedimen- tary rocks formed, geologists were satisfied with of the environment.
Only a few years ago, if you needed an appraisal of The revolution in the personal property appraisals gems and jewelry for any reason, you asked your local field (of which jewelry is a part) is a little more than a jeweler, who hastily scribbled a one-line handwritten decade old.
This book is for undergraduates, postgraduates and research workers who wish to gain an insight into present ideas and speculations on the origin of granite batholiths.
It has for some time been the author's opinion that the need exists for a complete, self-contained volume on hydrodynamics addressed to and written in an idiom for geologists and geophysicists actively engaged in the search for hydrocarbons.
The reserves, or extractable fraction, of the fuel-mineral endowment are sufficient to supply the bulk of the world's energy requirements for the immediately forseeable future-well into the next century according to even the most pessimistic predictions.
The seventy-fifth anniversary edition of the classic book about Cape Cod, "e;written with simplicity, sympathy, and beauty"e; (New York Herald Tribune)A chronicle of a solitary year spent on a Cape Cod beach, The Outermost House has long been recognized as a classic of American nature writing.
Isotope Ratio Mass Spectrometry of Light Gas-Forming Elements explores different methods of isotope analysis, including spark, secondary ion, laser, glow discharge, and isotope ratio mass spectrometry.
Providing a solid foundation for twenty-first-century scientists and engineers, Data Analysis and Statistics for Geography, Environmental Science, and Engineering guides readers in learning quantitative methodology, including how to implement data analysis methods using open-source software.
Structural Analysis of Polymeric Composite Materials, Second Edition introduces the mechanics of composite materials and structures and combines classical lamination theory with macromechanical failure principles for prediction and optimization of composite structural performance.
A thorough revision of the previous "e;Environmental Engineer's Mathematics Handbook,"e; this book offers readers an unusual approach to presenting environmental math concepts, emphasizing the relationship between the principles in natural processes and environmental processes.
Bridges the Gap between Geology and Ground EngineeringHigh-quality geological models are crucial for ground engineering projects, but many engineers are not always at ease with the geological terminology and analysis presented in these models, nor with their implications and limitations.
Includes Illustrative Applications of Practical Design CalculationsWritten in a straightforward style and user-friendly format, Practical Design Calculations for Groundwater and Soil Remediation, Second Edition highlights the essential concepts and important aspects of major design calculations used in soil and groundwater remediation.
Precision farming involves soil fertility and crop growth monitoring, electronic equipment, remote sensing, global information and positioning systems, computer models, decision support systems, variable-rate technology, and accurate recordkeeping.
Given the importance of interdisciplinary work in sustainability, Simulation of Ecological and Environmental Models introduces the theory and practice of modeling and simulation as applied in a variety of disciplines that deal with earth systems, the environment, ecology, and human-nature interactions.
Covering theory and practice, this wide-ranging introductory textbook covers the main optical properties of rock-forming minerals that can be recognized under the polarizing microscope.
The second edition of a bestseller, Soil and Water Chemistry: An Integrative Approach maintains the balanced perspective that made the first edition a hugely popular textbook.
The fifth edition of a bestseller, Air Quality provides students with a comprehensive overview of air quality, the science that continues to provide a better understanding of atmospheric chemistry and its effects on public health and the environment, and the regulatory and technological management practices employed in achieving air quality goals.
Practical statistics is a powerful tool used frequently by agricultural researchers and graduate students involved in investigating experimental design and analysis.
The study of animal movement has always been a key element in ecological science, because it is inherently linked to critical processes that scale from individuals to populations and communities to ecosystems.
This book presents the proceedings of the 30th International Geological Congress, providing information on geological hazards map and image analytical systems, mineral resources with integrated information, phase-separation analysis, mineral reserve estimation, and geosciences and management information systems.
This volume, based on Symposium on Igneous Petrology held during the 30th International Geological Congress, focuses on intraplate magmatism and diversity and complexity of mechanisms of magma formation.
