More than ever before, a compelling need exists for an encyclopedic resource about soil the rich mix of mineral particles, organic matter, gases, and soluble compounds that foster both plant and animal growth. Civilization depends more on the soil as human populations continue to grow and increasing demands are placed upon available resources.
The Encyclopedia of Soils in the Environmentis a comprehensive and integrated consideration of a topic of vital importance to human societies in the past, present, and future. This important work encompasses the present knowledge of the world's variegated soils, their origins, properties, classification, and roles in the biosphere. A team of outstanding, international contributors has written over 250 entries that cover a broad range of issues facing today's soil scientists, ecologists, and environmental scientists.
This four-volume set features thorough articles that survey specific aspects of soil biology, ecology, chemistry and physics. Rounding out the encyclopedia's excellent coverage, contributions cover cross-disciplinary subjects, such as the history of soil utilization for agricultural and engineering purposes and soils in relation to the remediation of pollution and the mitigation of global climate change.
This entry explains the use of emergy analysis to evaluate systems and compare resource use, environmental loading, and sustainability. This method allows the free contributions of the environment to be compared directly with the purchased inputs from the economy. Results summarized from agriculture and forestry systems indicate that extensive amounts of indirect energy were dissipated to yield agricultural and forest products and that timber typically requires less indirect energy than crops.
Первое издание энциклопедии по геофизике земли было издано в 1989 издательской компанией Вана Ностранда Реинхолда. Более двадцати лет спустя, это новое издание, отредактированное профессором Харшом К. Гупта, представляет полностью пересмотренную и расширенную работу. Энциклопедия объединяет более 200 статей, охватывающих уже установленные и новые концепции геофизики из различных разделов науки, таких как геодезия, геомагнетизм, сейсмология, глубинные земные процессы, тектоника плит, вычислительные методы, и т.д. в систематическом и последовательном формате. Это авторитетный источник информации благодаря вкладу редакторов и авторов со всего света, предназначенный для нынешних и будущих поколений профессионалов.
The major geomorphological divisions of the United States, the Rocky Mountain ranges, the Great Plains and the Appalachian ranges, do not have a major influence on coastal features. The Pacific coast follows the alignment of the Coast Ranges on the western side of the Rocky Mountains, the Great Plains run southward to the lowlying coast of the Gulf of Mexico, and the Appalachians extend north-eastward to the coast of Maine. Useful background is provided by Shepard and Wanless (1971), Sherman (2005), Thornbury (1965) and Graf (1987). <...>
Like other environmental hot-button issues familiar to us today—ocean pollution, forest loss, climate change, species endangerment, pathogen proliferation, the plasticpocalypse, and many others—biological extinction is very much in the public eye. This is surely a result of the growing realization, which now seems utterly inescapable, that humans have created, and continue to create, the kinds of circumstances in which species die out well before their time.
Программный комплекс «EngGeo» предназначен для работы с данными инженерно-геологических изысканий. Основными возможностями комплекса являются:
• хранение данных по бурению скважин, по лабораторным пробам грунтов и вод, по полевым испытаниям; • расчет физико-механических и химических характеристик грунтов и вод и их статистическая обработка; • создание текстовых отчетов по испытаниям и проходке выработок; • построение чертежей колонок скважин и разрезов.
This section includes a brief description of the technical activities of the Gas Processors Association (GPA) and the Gas Processors Suppliers Association (GPSA). It includes a compilation of current GPA standards, publications, and Research Reports, a glossary of terms used in the gas processing industry and several tables of common conversion factors and equivalents. At the end of the Section is a listing of other technical associations and societies that publish codes, standards and other information pertinent to the natural gas processing industry <...>
As noted in the Preface to the first edition, engineering geology can be defined as the application of Geology to engineering practice. In other words, it is concerned with those geological factors that influence the location, design, construction and maintenance of engineering works. Accordingly, it draws on a number of geological disciplines such as geomorphology, structural geology, sedimentology, petrology and stratigraphy. In addition, engineering geology involves hydrogeology and some understanding of rock and soil mechanics.
Similar to the first edition, this edition too is written for undergraduate and post-graduate students of engineering geology. It is hoped that this will also be of value to those involved in the profession, especially at the earlier stages of their careers. However, it is aimed at not just engineering geologists but also at those in civil and mining engineering, water engineering, quarrying and, to a lesser extent, architecture, planning, surveying and building. In other words, those who deal with the ground should know something about it.
