Microbial Biomass informs readers of the ongoing global revolution in understanding soil and ecosystem microbial processes. The first paper on the subject was written by David Jenkinson in 1966, and here new insights and expansions are given on the fascinating world of soil microbial processes. In terms of contemporary issues, it also serves to support urgent efforts to sustainably manage land to feed a growing world population without compromising the environment. It presents new methods of investigation which are leading to more sustainable management of ecosystems, and improved understanding of ecosystem changes in an increasingly warmer world.The book approaches the topic by looking at the emergence of our understanding of soil biological processes, and begins by tracing the conception and first measurement of soil microbial biomass. Following this, changes in ecosystems, and in natural ecosystem processes are discussed in relation to land management issues and global change. Microbial biomass and its diversity are recognized as key factors in finding solutions for more sustainable land and ecosystem management, aided by new molecular and other tools. Information from the use of these tools is now being incorporated into emerging microbial-explicit predictive models, to help us study changes in earth system processes.Perfect for use in research and practice, this book is written for undergraduate and graduate students, researchers and professionals of agronomy, chemistry, geology, physical geography, ecology, biology, microbiology, silviculture and soil science.

In the field of mechanism design, kinematic synthesis is a creative means to produce mechanism solutions. Combined with the emergence of powerful personal computers, mathematical analysis software and the development of quantitative methods for kinematic synthesis, there is an endless variety of possible mechanism solutions that users are free to explore, realize, and evaluate for any given problem in an efficient and practical manner. Mechanism Design: Visual and Programmable Approaches provides a broad introduction to kinematic synthesis, presenting and applying motion, path, and function generation methodologies for some of the most basic planar and spatial single and multi-loop linkage systems. This work provides numerous in-chapter synthesis examples and end-of-chapter synthesis problems. Users can also invent their own specialized synthesis problems according to their particular interests. The commercial mathematical software package MATLAB (R) and its mechanical system modeling and simulation module SimMechanics (R) are thoroughly integrated in this textbook for mechanism synthesis and analysis. The reader is therefore enabled to readily apply the design approaches presented in this textbook to synthesize mechanism systems and visualize their results. With this knowledge of both kinematic synthesis theory and computer-based application, readers will be well-equipped to invent novel mechanical system designs for a wide range of applications.
