Principles and Practice of Ground Improvement
Gain a stronger foundation with optimal ground improvement Before you break ground on a new structure, you need to analyze the structure of the ground. Expert analysis and optimization of the geo-materials on your site can mean the difference between a lasting structure and a school in a sinkhole. Sometimes problematic geology is expected because of the location, but other times it’s only unearthed once construction has begun. You need to be able to quickly adapt your project plan to include an improvement to unfavorable ground before the project can safely continue. Principles and Practice of Ground Improvement is the only comprehensive, up-to-date compendium of solutions to this critical aspect of civil engineering. Dr. Jie Han, registered Professional Engineer and preeminent voice in geotechnical engineering, is the ultimate guide to the methods and best practices of ground improvement. Han walks you through various ground improvement solutions and provides theoretical and practical advice for determining which technique fits each situation. * Follow examples to find solutions to complex problems * Complete homework problems to tackle issues that present themselves in the field * Study design procedures for each technique to simplify field implementation * Brush up on modern ground improvement technologies to keep abreast of all available options Principles and Practice of Ground Improvement can be used as a textbook, and includes Powerpoint slides for instructors. It’s also a handy field reference for contractors and installers who actually implement plans. There are many ground improvement solutions out there, but there is no single right answer to every situation. Principles and Practice of Ground Improvement will give you the information you need to analyze the problem, then design and implement the best possible solution.
The first edition of “Microstrip Filters for RF/Microwave Applications” was published in 2001. Over the years the book has been well received and is used extensively in both academia and industry by microwave researchers and engineers. From its inception as a manuscript the book is almost 8 years old. While the fundamentals of filter circuits have not changed, further innovations in filter realizations and other applications have occurred with changes in the technology and use of new fabrication processes, such as the recent advances in RF MEMS and ferroelectric films for tunable filters; the use of liquid crystal polymer (LCP) substrates for multilayer circuits, as well as the new filters for dual-band, multi-band and ultra wideband (UWB) applications.
Although the microstrip filter remains as the main transmission line medium for these new developments, there has been a new trend of using combined planar transmission line structures such as co-planar waveguide (CPW) and slotted ground structures for novel physical implementations beyond the single layer in order to achieve filter miniaturization and better performance.
Also, over the years, practitioners have suggested topics that should be added for completeness, or deleted in some cases, as they were not very useful in practice.
In view of the above, the authors are proposing a revised version of the “Microstrip Filters for RF/Microwave Applications” text and a slightly changed book title of “Planar Filters for RF/Microwave Applications” to reflect the aforementioned trends in the revised book.

Social work is the profession that claims to intervene to enhance people’s well-being. However, social workers have played a low-key role in environmental issues that increasingly impact on people’s well-being, both locally and globally.
This compelling new contribution confronts this topic head-on, examining environmental issues from a social work perspective. Lena Dominelli draws attention to the important voice of practitioners working on the ground in the aftermath of environmental disasters, whether these are caused by climate change, industrial accidents or human conflict. The author explores the concept of ‘green social work’ and its role in using environmental crises to address poverty and other forms of structural inequalities, to obtain more equitable allocations of limited natural resources and to tackle global socio-political forces that have a damaging impact upon the quality of life of poor and marginalized populations at local levels. The resolution of these matters is linked to community initiatives that social workers can engage in to ensure that the quality of life of poor people can be enhanced without costing the Earth.
This important book will appeal to those in the fields of social work, social policy, sociology and human geography. It powerfully reveals how environmental issues are an integral part of social work’s remit if it is to retain its currency in the modern world and emphasize its relevance to the social issues that societies have to resolve in the twenty-first century.

Transportation is arguably the most critical component of global supply chains. And one of the most complex. Delivering comprehensive coverage of current domestic and global transportation trends, “Management Transportation, 7e, International Edition” equips your students with a solid understanding of this dynamic field. More student friendly than ever, the seventh edition helps readers understand both the fundamental role and importance of transportation in companies and in society, as well as the complex environment in which transportation service is provided today. Taking a managerial approach, the authors give students the tools to successfully adapt to this fast-paced and rapidly changing industry. The text is organized into three parts. Part I provides a framework and foundation for the role of transportation from a micro and macro perspective in supply chains. Discussions include both the theoretical and managerial dimensions of transportation in supply chains, including regulation and public policy. Part II focuses on the providers of transportation, offering an industry overview, operating and service characteristics, cost structure, and current challenges and issues. Part III focuses on a variety of critical transportation management issues, providing insightful discussions of the strategic activities and challenges involved in the movement of goods through the supply chain.
Pozar’s new edition of Microwave Engineering includes more material on active circuits, noise, nonlinear effects, and wireless systems. Chapters on noise and nonlinear distortion, and active devices have been added along with the coverage of noise and more material on intermodulation distortion and related nonlinear effects. On active devices, there’s more updated material on bipolar junction and field effect transistors.
New and updated material on wireless communications systems, including link budget, link margin, digital modulation methods, and bit error rates is also part of the new edition. Other new material includes a section on transients on transmission lines, the theory of power waves, a discussion of higher order modes and frequency effects for microstrip line, and a discussion of how to determine unloaded.
