Stream Ecology by Allan and Castillo is extensively revised and updated from the successful first edition to include major developments over the past decade. Although the subject matter is relatively advanced, this book has been written with the express goal of being accessible to students with only modest backgrounds in ecology and aquatic sciences. The First Edition was widely praised for its readability, and that emphasis is retained. The second edition opens with a new introductory chapter that sets the stage for what follows. The treatment of geomorphology and hydrology are greatly expanded from the first edition, and have been split into two, more substantial chapters. Basal energy resources, trophic roles and food web interactions are retained but thoroughly updated, particularly to include recent advances in microbial ecology and the synergies between producers and decomposers. The discussion of species interactions has been re-organized so that modern topics receive more emphasis, including trophic cascades, subsidies and food web structure. Chapters on organic matter dynamics and nutrient cycling have been substantially re-written to reflect the enormous growth in knowledge of stream metabolism and nutrient processes, the core of ecosystem functioning. The closing chapter on human impacts summarizes the status of river ecosystems and principal threats, and new material that describes advances in river management including the science of environmental flows, the successes and failures of river restoration, and the potential for ecosystem-based catchment management.

Designing with Structural Steel A Guide for Architects
Alford Johnson
American Institute of Steel Construction, Inc.
2nd edition, 2002
ISBN 1564240525
PDF 2.3 MB
374 pages
The purpose of this Guide is to provide architects with the tools needed to feel more comfortable and confident working with structural steel in building projects. With a greater understanding of the characteristics and inherent benefits of structural steel, architects will be prepared to better utilize steel as a framing material. Some of the strengths structural steel offers in building design is high resiliency and performance under harsh and difficult conditions, i.e., earthquakes and hurricanes. Steel offers the ability to span great distances with slenderness and grace. Steel can be shaped to achieve curved forms and goes up quickly to meet tough construction schedules in almost any weather condition. Steel can be easily modified in the future to satisfy changing requirements.

Any nonlinear theories or finite elements have to be tested before they can be put into practice. Using the rigid body concept, this book provides simple rules for examining the validity of nonlinear theories and finite elements derived for structural members. The rules can be applied as well to testing the consistency of existing theories or computer analysis programs for nonlinear structures. Covers linear analysis and element quality test; nonlinear trusses and incremental constitutive laws; nonlinear analysis of planar frames; fundamentals of nonlinear theory of space frames; stiffness matrices for nonlinear analysis of space frames; theory and analysis on buckling of curved beams; and procedures for geometric nonlinear analysis. Provides numerous examples containing both analytical and numerical solutions. For mechanical, civil, and aerospace engineers

Principles of Foundation Engineering - 5th Edition
info:
Product Description
Braja M. Das' Fifth Edition of PRINCIPLES OF FOUNDATION ENGINEERING maintains the careful balance of current research and practical field applications that has made it the leading text in foundation engineering courses. Featuring a wealth of worked-out examples and figures that help students with theory and problem-solving skills, the book introduces civil engineering students to the fundamental concepts and application of foundation analysis design. Throughout, Das emphasizes the judgment needed to properly apply the theories and analysis to the evaluation of soils and foundation design as well as the need for field experience.
About the Author
Dr. Braja M. Das has been the Dean of the School of Engineering and Computer Science from August 1994 to the present at California State University, Sacramento. Prior to 1994, he was the Associate Vice President for Academic Affairs and Research at Southern Illinois University at Carbondale, Illinois. The author of more than 200 technical papers, his primary areas of research are shallow foundations, earth anchors, and geosynthetics. He received his Ph.D. from the University of Wisconsin, Madison.
