From a mechanical perspective, an animal's shape and the topological connection of its organs are important factors in locomotion. This book describes the physical relationships between form, habitat, way of life, and movement in living creatures. It includes in-depth mechanical and mathematical analyses of the way in which creatures move about, and it also investigates dispersal modes of plants and animals within the framework of flying and swimming. The book is written from the viewpoint of mechanics, specifically fluid dynamics and flight dynamics, rather than from that of physiology and ecology. It will prove a useful reference for aeronautical and mechanical engineers as well as for biologists who use mechanical analyses in the study of behaviour, function, and locomotion.

The oil and gas engineer on the job requires knowing all the available oil field chemicals and fluid applications that are applicable to the operation. Updated with the newest technology and available products, Petroleum Engineer's Guide to Oil Field Chemicals and Fluids, Second Edition, delivers all the necessary lists of chemicals by use, their basic components, benefits, and environmental implications. In order to maintain reservoir protection and peak well production performance, operators demand to know all the options that are available. Instead of searching through various sources, Petroleum Engineer's Guide to Oil Field Chemicals and Fluids, Second Edition, presents a one-stop non-commercialized approach by organizing the products by function, matching the chemical to the process for practical problem-solving and extending the coverage with additional resources and supportive materials. Covering the full spectrum, including fluid loss additives, drilling muds, cement additives, and oil spill treating agents, this must-have reference answers to every oil and gas operation with more options for lower costs, safer use, and enhanced production. - Effectively locate and utilize the right chemical application specific to your oil and gas operation with author's systematic approach by use - Gain coverage on all oil field chemicals and fluids needed throughout the entire oil and gas life cycle, including drilling, production, and cementing - Understand environmental factors and risks for oil field chemicals, along with pluses and minuses of each application, to make the best and safest choice for your operation

The Symposium on Swimming and Flying in Nature which was held at the California Institute of Technology, Pasadena, California from July 8-12, 1974 was conceived with the objective of providing an interdisciplinary forum for the discussion of funda mental biological and fluid mechanical aspects of these forms of natura110comotion. It was the earnest hope of all concerned in the organization of the Symposium that the exchange of knowledge and interaction of ideas from the disciplines involved would stimu late new research in this developing field. If the liveliness of the discussion generated among the 250 or so participants is any measure, then this objective was fulfilled to a significant degree. These two companion volumes contain the manuscripts of the papers presented during the Symposium. It is hoped that this permanent record will serve to perpetuate the enthusiasm and active thought generated during those days in Pasadena. The first volume contains the proceedings of the first two days of the confer ence (Sessions I to IV) which concentrated on the locomotion of micro-organisms. The second volume (Sessions V to VIII) deals with the propulsion of larger fish, insects and birds. Professor Sir James Lighthill's Special Invited Lecture which opened the Symposium is contained in the second volume, rather than the first, since it deals with natural flight.
