Chasing the Chinese dream : Four decades of following China’s war on poverty
This book explores the historical, cultural and philosophical contexts that have made anti-poverty the core of Chinese society since Liberation in 1949, and why poverty alleviation measures evolved from the simplistic aid of the 1950s to Xi Jinping’s precision poverty alleviation and its goal of eliminating absolute poverty by 2020. The book also addresses the implications of China’s experience for other developing nations tackling not only poverty but such issues as pandemics, rampant urbanization and desertification exacerbated by global warming. The first of three parts draws upon interviews of rural and urban Chinese from diverse backgrounds and local and national leaders. These interviews, conducted in even the remotest areas of the country, offer candid insights into the challenges that have forced China to continually evolve its programs to resolve even the most intractable cases of poverty.

Characterization of Corrosion Products on Steel Surfaces
It is well known that corrosion products, i.e. rust, on iron and steel surfaces cannot be assigned a typical crystallographic structure with long-range order. In fact, the structure of rust is considered to be very complicated, and some forms of rust are assigned to the amorphous state for this reason. Accurate information about the atomic-scale structure of rust is important to shed light on corrosion mechanisms of metallic materials. And, since life of steel structures is often dominated by environmental degradation or corrosion of the surface, the structure of the rust formed on iron and steel surfaces during prolonged exposure to air is of great interest. This book describes the fundamental aspects of materials characterization for the ferric oxyhydroxides formed on steel surfaces.
Characteristics Finite Element Methods in Computational Fluid Dynamics
This book details a systematic characteristics-based finite element procedure to investigate incompressible, free-surface and compressible flows. The fluid dynamics equations are derived from basic thermo-mechanical principles and the multi-dimensional and infinite-directional upstream procedure is developed by combining a finite element discretization of a characteristics-bias system with an implicit Runge-Kutta time integration. For the computational solution of the Euler and Navier Stokes equations, the procedure relies on the mathematics and physics of multi-dimensional characteristics. As a result, the procedure crisply captures contact discontinuities, normal as well as oblique shocks, and generates essentially non-oscillatory solutions for incompressible, subsonic, transonic, supersonic, and hypersonic inviscid and viscous flows.
Character Evidence : An Abductive Theory
This book is on evidence for character judgments, This book answers the question using a model of abductive reasoning, commonly called inference to the best explanation. The methodology of the book derives from recent work on models of reasoning in argumentation theory and artificial intelligence. The aim is not just to show how character judgments are made, but to show how they should be properly be made based on sound reasoning, in order to avoid errors and superficial judgments of a kind that are common.
Chaperones
Molecular chaperones interact with virtually every newly synthesized protein. Their role is not limited to this, as an increasing number of protein-protein interactions are found to be mediated by molecular chaperones. They reside in large complexes, in every cellular compartment, and to some extent even outside cells. These proteins are of interest to a large number of scientists, not only to those interested in protein biosynthesis, but also in relation to protein transport, organelle biogenesis, and cell stress.
Chaos, Nonlinearity, Complexity : The Dynamical Paradigm of Nature
This carefully edited book presents a focused debate on the mathematics and physics of chaos, nonlinearity and complexity in nature. It explores the role of non-extensive statistical mechanics in non-equilibrium thermodynamics, and presents an overview of the strong nonlinearity of chaos and complexity in natural systems that draws on the relevant mathematics from topology, measure-theory, inverse and ill-posed problems, set-valued analysis, and nonlinear functional analysis. It presents a self-contained scientific theory of complexity and complex systems as the steady state of non-equilibrium systems, denoting a homeostatic dynamic equilibrium between stabilizing order and destabilizing disorder.
