Trends in Airborne Equipment for Agriculture and Other Areas is a collection of papers presented at a Seminar on Techno-economic Trends in Airborne Equipment for Agriculture and other Selected Areas of the National Economy (Aero-agro '78), organized by the United Nations Economic Commission for Europe and held in Warsaw, Poland, on September 18-22, 1978. Contributors examine the role of airborne equipment in agriculture and other areas from the perspectives of economic, technical and environmental concerns. Attention is paid to the value of soil surveys and land evaluation maps and of biogeographical analyses of pest outbreaks in planning aerial application operations. This book is comprised of 45 chapters and begins with a discussion on the economic aspects of airborne equipment, with emphasis on the value of bio-aeronautics in crop production and protection and of aircraft in the management of biological resources. Among the many techniques to improve economic efficiency, speed and timing are highlighted. The technical design and operation of equipment for aircraft are also considered, along with the use of helicopters as airborne cranes for a wide range of applications such as building construction and geological surveys. The results of experiments on the corrosive effects of pesticides, both in water and oil suspensions, are presented. A non-polluting insecticide particularly suited for ultra-low volume operations is also described, together with the use of light aircraft for fighting forest fires. This monograph will be a valuable resource for economists and agriculturists as well as policymakers in both areas.

Prepared by some of the world's leading experts in the field, this book is the first summarizing work on the origin, importance and exploitation of paleokarst. It offers an extensive regional survey, mainly concerning the Northern Hemisphere, as well as a thorough analysis of the problems of research into paleokarst phenomena, with particular emphasis on theoretical contributions and practical exploitation. By concentrating on phenomena which have appeared in the course of geological history, the book represents a substantial development in the general theory of paleokarst and demonstrates the advantages of a comprehensive approach to the problem. Considerable emphasis is put on the economic importance of paleokarst phenomena, from the point of view of exploiting significant deposits of mineral raw materials, as well as from a civil engineering and hydrological point of view. Since the publication deals with a boundary scientific discipline, it is intended for specialists from various branches of science: geologists, paleontologists, economic geologists, geographers, mining engineers and hydrogeologists.

Frozen Ground Engineering first introduces the reader to the frozen environment and the behavior of frozen soil as an engineering material. In subsequent chapters this information is used in the analysis and design of ground support systems, foundations, and embankments. These and other topics make this book suitable for use by civil engineering students in a one-semester course on frozen ground engineering at the senior or first-year-graduate level. Students are assumed to have a working knowledge of undergraduate mechanics (statics and mechanics of materials) and geotechnical engineering (usual two-course sequence). A knowledge of basic geology would be helpful but is not essential. This book will also be useful to advanced students in other disciplines and to engineers who desire an introduction to frozen ground engineering or references to selected technical publications in the field. BACKGROUND Frozen ground engineering has developed rapidly in the past several decades under the pressure of necessity. As practical problems involving frozen soils broadened in scope, the inadequacy of earlier methods for coping became increasingly apparent. The application of ground freezing to geotechnical projects throughout the world continues to grow as significant advances have been made in ground freezing technology. Freezing is a useful and versatile technique for temporary earth support, groundwater control in difficult soil or rock strata, and the formation of subsurface containment barriers suitable for use in groundwater remediation projects.
