Global Cooperation Among G20 Countries

Global Cooperation Among G20 Countries

At the outbreak of the global financial crisis, 2008, the G20 was widely acknowledged as helping prevent an even more serious decline in the global economy. It helped to calm the panic in financial markets and articulate a set of possible policy options to restore global stability and growth. However, as the dual-track recovery set in, policy options for advanced economies and EMEs diverged. Within this context, this book will explore the scope for cooperation amongst the G20 and the diverging challenges and the intricate interconnectedness of policy options between advanced economies and the EMEs within the G20.

Movement, Stability and Lumbopelvic Pain

Movement, Stability and Lumbopelvic Pain

The human pelvis has become a focus for a considerable amount of new research, which is relevant to manual therapy practice. In particular, movement within the pelvis is now being recognized and studied in relation to its role in maintaining stability in the vertebral column and subsequent implications for the prevention and treatment of low back pain. This important subject area is covered in depth in this new edition. The contributors represent the breadth of professionals involved in manual therapy, from osteopathy, chiropractic and manual physical therapy, to orthopaedic medicine and surgery, anaesthesia and pain control.

Energetic Materials

Energetic Materials

Incorporation of particular components with specialized properties allows one to tailor the end product’s properties. For instance, the sensitivity, burning behavior, thermal or mechanical properties or stability of energetic materials can be affected and even controllably varied through incorporation of such ingredients. This book examines particle technologies as applied to energetic materials such as propellants and explosives, thus filling a void in the literature on this subject.

Power System Oscillations

Power System Oscillations

Power System Oscillations deals with the analysis and control of low frequency oscillations in the 0.2-3 Hz range, which are a characteristic of interconnected power systems. Small variations in system load excite the oscillations, which must be damped effectively to maintain secure and stable system operation. No warning is given for the occurrence of growing oscillations caused by oscillatory instability, since a change in the system’s operating condition may cause the transition from stable to unstable. If not limited by nonlinearities, unstable oscillations may lead to rapid system collapse. Thus, it is difficult for operators to intervene manually to restore the system’s stability. It follows that it is important to analyze a system’s oscillatory behavior in order to understand the system’s limits. If the limits imposed by oscillatory instability are too low, they may be increased by the installation of special stabilizing controls.

Rails AntiPatterns

Rails AntiPatterns

As developers worldwide have adopted the powerful , on , web framework, many have fallen victim to common mistakes that reduce code quality, performance, reliability, stability, scalability, and maintainability. Rails AntiPatterns identifies these widespread Rails code and , problems, explains why they’re bad and why they happen – and shows exactly what to do instead.,

The book is organized into concise, modular chapters – each outlines a single common AntiPattern and offers detailed, cookbook-style code solutions that were previously difficult or impossible to find.
