Book Description

One of the most widely used techniques for treating soils contaminated with volatile organic compounds, soil vapor extraction (SVE) can also be applied to semi-volatile organic compounds (SVOCs) if the soil is heated, by applying electromagnetic energy in the radio frequency (FR) range, to increase the vapor pressure of the contaminants. Although RF-SVE systems used in previous field demonstrations have had varying degrees of success, questions remain concerning its viability and cost-effectiveness.Soil Vapor Extraction Using Radio Frequency Heating: Resource Manual and Technology Demonstration covers detailed scientific and engineering information that answers these questions. The book includes the necessary databases, equations, and example calculations for RF heating. The theoretical and practical information included will facilitate future testing of RF-SVE treatment of soils. Additionally, the book provides information for a full-scale engineering design of potential RF-SVE applications. The authors use this information to examine predicted performance, magnitude of costs, and modifications to the design that may decrease cost. Soil Vapor Extraction Using Radio Frequency Heating: Resource Manual and Technology Demonstration gives an economic analysis of this innovative technology and considers other possible applications for it.Features ...

Book Description

This collection contains contributions from leading researchers on the engineering behaviour of unsaturated soil. It includes contributions dealing with the measurement of suction, discussions about how pore-water affects the engineering behaviour of soils and the important role played by soil--water characteristic (water retention) curves. This leads on to applications of unsaturated soil behaviour within geotechnical engineering practice, dealing with collapsible soils, foundations, and slopes.The collection is valuable both in contributing to the research effort on unsaturated soil behaviour and also in showing how unsaturated soil concepts can be applied within geotechnical engineering practice. It shows how researchers are making significant headway in establishing rational approaches to dealing with these complex circumstances.Audience: This book will be of interest to both researchers and practitioners dealing with unsaturated soil behaviour. ...

Book Description

Many agronomic reference books either focus on a single crop, several related crops, or specific soil topics but not on a full range of both crop and soil subjects. This unique handbook covers both major agronomic fields. Containing essential data and information on the culture of the world's major agronomic grain, oil, fiber, and sugar crops grown on a wide range of soil types, Agronomic Handbook: Management of Crops, Soils, and Their Fertility serves as a practical reference on the management of crops and soils from planting to harvest. This handbook provides you with:· A list of definitions· A glossary of botanical terms· Nutrient element requirement levels for the major agronomic crops· A list of troublesome weeds· A key to nutrient element deficiency syndrome of legumes· A summary of the characteristics of the major elements and micronutrients· The basic information needed to develop cultural, liming, and fertilizer recommendations· Diagnostic procedures for assessing the fertility status of soils and the nutrient element status of plants Written in the author's trademark, practical style, this handbook describes the genetic history, yield characteristics, cultural requirements, and nutritional requirements of the major agronomic crops; the physical and chemical properties of major soil types; and the composition, formulation, and uses of fertilizers. Crop characteristics are provided including national and international statistics, world production figures, and information on changing crop conditions.With its wide range of fundamental information on crops and soils, the Agronomic Handbook will be an invaluable reference for those preparing for the Certified Crop Advisor Exam and anyone engaged in agronomic production, study, and research.

Book Description

The production of a vast array of chemicals, especially petroleum compounds during the last century, has caused a serious deterioration in environmental quality. In this context, one major threat is posed by the continually expanding areas of contaminated soils and sediments. Biotechnological methods based on the biodegradation of environmental pollutants or phytoremediation of persistent organic contaminants and metals are being developed. Bioremediation has been used successfully to remediate many petroleum-contaminated sites. However, there are as yet no commercial technologies commonly used to remediate the most recalcitrant contaminants, such as explosives, pesticides and metallic pollutants. Nevertheless, bioremediation is a rapidly advancing field and new bio-based remedial technologies are continuing to emerge. For this volume, a number of experts from universities, government laboratories and industry, have contributed chapters on innovative methods in bioremediation and phytoremediation. ... Read more

Book Description

The archaeological geology of the Quaternary or the geological epoch during which humankind evolved is a scientific endeavor with much to offer in the fields of archaeology and palaeoanthropology. Earth science techniques offer diverse ways of characterizing the elements of past landscapes and archaeological facies. This book is a survey of techniques used in archaeological geology for the study of soils, sediments, rocks and minerals. The techniques presented represent those most commonly used today. They are discussed in detail and examples are provided, in many cases, to demonstrate their usefulness to archaeologists. ... Read more

Book Description

Several long-term trends in technology evolution have become apparent since these symposia began in 1989. Earlier presenters more frequently discussed treatment methods involving harsh and extensive human intervention. As the symposia have continued, the number of presentations describing extremely harsh and expensive treatment technologies have gradually been supplanted by more subtle and gentler methods. Such methods include subsurface-engineered barriers, phytoremediation, and bioremediation.Nineteen manuscripts were selected for inclusion in this volume, based upon peer review, scientific merit, the editors' perceptions of lasting value or innovative features, and the general applicability of either the technology itself or the scientific methods and scholarly details provided by the authors. General topics include: soil treatment, groundwater treatment, and radioactive waste treatment. ... Read more

Book Description

This volume reviews the microtextural literature of the last twenty-five years since thepublication of Sand Grain Surface Texures by D.H. Krinsley and J. Doornkamp, in 1973, which inaugurated the use of the SEM in sedimentology. For over four decades, the SEM has proved itself to be the instrument of choice in the analysis of microstructures, whether they be mineral collages or intergrowths, whole grain or partial grain microfeatures including microtextures, dissolution characteristics and/or precipitates-coatings of various thicknesses and compositions. Its high resolution stereo imagery, coupled with energydispersive spectrometry, provides a level of compositional analysis that far exceeds the traditional light microscope. With magnifications from 25 to 100,000X, virtually the surface of any molecualr structure can be seen and studied from microphotographs or electronic imagery together with printouts from an interlinked energy dispersive spectrometer (EDS). Offering an expanded list of microtextures, new interpretations of them and an assessment of how they may be used to discriminate sedimentary environments, this volume builds on the original "Atlas" and the work of practitioners worldwide. Including engineering tests designed to reproduce "glacial grains" under controlled conditions in the laboratory, new information on microtextures of heavy minerals, applications in the earth, forensic, archaeologic, and nutrition sciences, together with the use of the secondary and CL modes of the SEM, this book is a state-of-the-art presentation of where sand grain microfeature analysis lies at present and where it intends to go in the future. ...
