This open access book is the first comprehensive guideline for the beryllium-7 (Be-7) technique that can be applied to evaluate short-term patterns and budgets of soil redistribution in agricultural landscapes. While covering the fundamental and basic concepts of the approach, this book distinguishes itself from other publications by offering step-by-step instructions on how to use this isotopic technique effectively. It covers experimental design considerations and clear instruction is given on data processing. As accurate laboratory measurement is crucial to ensure successful use of Be-7 to investigate soil erosion, a full chapter is devoted to its specific determination by gamma spectrometry. This open access contribution further describes new developments in the Be-7 technique and includes a concluding chapter highlighting its potential benefits to support the implementation of area-wide soil conservation policy.

Описание: Diverse as they are in their histories and in the organization of their forest sectors, most Nordic countries have this in common: their economies and cultures are substantially based on the utilization of various forest resources. This book explores Nordic forest futures and presents research results that form part of a scientific foundation for considering how to balance the functions of forests. It is particularly concerned with global trends that may affect the future use of boreal forests. Chapters investigate inter-alia the growing world population and the expected economic growth in countries with huge populations, and assess the resulting pressure on all land-based resources. Authors examine the urgent need for solutions to the energy crisis, consider worrying climate scenarios and provide a global outlook on bioenergy futures. Readers will discover how these developments will and must influence long-term strategic decisions on the future use of Nordic forests. The challenges and possible responses for future forest governance and forestry issues emerge, as the chapters go on to consider the multiple pressures in particular on the Swedish Forestry Model, among other themes. “By bringing together a distinguished group of internationally renowned scientists representing a diverse set of disciplines covering political science, geography, rural development, forest economics, history, and geo-sciences, this book constitutes an exceptionally profound and thoughtful futures study.” – Alexander Buck, Executive Director, International Union of Forest Research Organizations (IUFRO)

Описание:
Concerns over energy resources and the environmental impact of energy use will continue to be part of the polical agenda across the globe. World Scientific's unique series of books on Current Energy Issues is intended, in part, as an expansion and update of the material contained in the World Scientific Handbook of Energy but in part each volume will focus on related energy resources or issues that contain a broader range of topics plus more explanatory text than was possible in the Handbook. The authors will also take the opportunity to update the data presented in the Handbook since in many cases the field is rapidly changing.
The Fossil Fuels volume focuses on the main fossil resources, viz. coal, oil and natural gas. Coal is still an extremely important resource especially for electricity production around the world and the book discussed methods for making coal a cleaner resource, including carbon sequestration. There has been a rapid change in the mix of fossil fuels mainly because of hydraulic fracturing which enables oil and gas to be extracted from previously inaccessible formations. The book describes this changing situation including the precautions required to make the production of these fuels safe and environmentally benign. Alternative fossil fuels such as methane hydrates are also discussed.

Описание: Coal preparation plants are designed to clean impurities, such as soil, sand and rock from coal, to ready it for transportation to power plants and coking facilities for use in steel processing. Monitoring flow through the coal preparation process can be difficult as the coal is abrasive and can cause inaccuracies and maintenance issues for intrusive instruments. A Coal preparation plant generally use gravity process equipment to separate the refuse from the product (coal). Coal has a specific gravity between 1.35 and 1.5, while the refuse rock has a Specific Gravity of 2.1 to 2.3. Heavy Media is the most popular method of cleaning coarse sizes. Heavy media cyclones are being used more often for fines size fractions. Flotation is generally used to clean the -28 mesh size fraction, although spirals and heavy media cyclones have shown success in cleaning down to 100 mesh coal feed. Spirals are generally used for middling sizes. Modular Coal Preparation Plants (MCPP) prepares coal for a cleaner burning process, enhanced calorific value and cleaner emissions. MCPPs consist of several modules including a raw coal preparation (crushing and screening station), a coal feed and washing module (jigging and Heavy Medium cyclone) as well as a dewatering module. Designing the Coal Preparation Plant of the Future provides comprehensive overview on several current and future challenges that must be considered in the design and operation of coal preparation facilities. These challenges dictate that we constantly strive to improve plant. Coal Preparation Engineers are meeting this challenge of the future by designing large modem environmentally acceptable plants.
Описание: This book presents a comprehensive collection of articles illustrating the importance of microbial community structure and function for ecosystem sustainability and environmental reclamation. It addresses a diverse range of topics, including microbial diversity, physiology, genomics, ecosystem function, interaction, metabolism, and the fruitful use of microbial communities for crop productivity and environmental remediation. In addition, the book explores issues ranging from general concepts on the diversity of microorganisms in soil, and ecosystem function, to the evolution and taxonomy of soil microbiota, with future prospects. It covers cutting-edge methods in soil microbial ecological studies, rhizosphere microflora, the role of organic matter in plant productivity, biological nitrogen fixation and its genetics, microbial transformation of plant nutrients in soil, plant-growth-promoting rhizobacteria, and organic matter transformation. The book also discusses the application of microbes in biodegradation of xenobiotic contaminants. It covers bio-fertilizers and their role in sustainable agriculture and soil health, biological control of insect pests and plant pathogens, and the latest tools of omics in soil microbiology, i.e. genomics, proteomics, transcriptomics and metabolomics, which offer pioneering approaches to the exploration of microbial structure and function.
