Since the first edition of this book, the literature on fitted mesh methods for singularly perturbed problems has expanded significantly. Over the intervening years, fitted meshes have been shown to be effective for an extensive set of singularly perturbed partial differential equations. In the revised version of this book, the reader will find an introduction to the basic theory associated with fitted numerical methods for singularly perturbed differential equations. Fitted mesh methods focus on the appropriate distribution of the mesh points for singularly perturbed problems. The global errors in the numerical approximations are measured in the pointwise maximum norm. The fitted mesh algorithm is particularly simple to implement in practice, but the theory of why these numerical methods work is far from simple. This book can be used as an introductory text to the theory underpinning fitted mesh methods.

India S Economy, Which For Decades Was Stuck With The So-Called Hindu Rate Of Growth Around 3 Per Cent, Has Hit The 9 Per Cent Mark For The Last Two Consecutive Years. Leading Economists Hold That The Growth Can Be Sustained In The Coming Years If The Government Can Put In Place More Reforms And Implement Them. There Is No Denying The Fact That The Initiatives Taken In The Early 1990S Continue To Bring Rich Rewards And Have Enabled India To Have The Fourth Largest Gdp In The World In Terms Of Purchasing Power. The Policy-Driven Reforms Have Taken Our Country From The Third World Status To One That Plays An Important Role In Defining The Fate Of The Global Economy. The Country Is In The Midst...
Plants face a daunting array of creatures that eat them, bore into them, and otherwise use virtually every plant part for food, shelter, or both. But although plants cannot flee from their attackers, they are far from defenseless. In addition to adaptations like thorns, which may be produced in response to attack, plants actively alter their chemistry and physiology in response to damage. For instance, young potato plant leaves being eaten by potato beetles respond by producing chemicals that inhibit beetle digestive enzymes. Over the past fifteen years, research on these induced responses to herbivory has flourished, and here Richard Karban and Ian T. Baldwin present the first comprehensive evaluation and synthesis of this rapidly developing field. They provide state-of-the-discipline reviews and highlight areas where new research will be most productive. Their comprehensive overview will be welcomed by a wide variety of theoretical and applied researchers in ecology, evolutionary biology, plant biology, entomology, and agriculture.
This Publication is an effort to increase visibility and recognition of the internal migration phenomenon in India ,disseminate experiences and practices ,and provoke a paradigm shift in the perception and portrayal of migrants by addressing myths and misconceptions and creating awareness on the benefits of migrants in society.
Inducible defenses--those often dramatic phenotypic shifts in prey activated by biological agents ranging from predators to pathogens--are widespread in the natural world. Yet research on the inducible defenses used by vertebrates, invertebrates, and plants in terrestrial, marine, and freshwater habitats has largely developed along independent lines. Tollrian and Harvell bring together leading researchers from all fields to review common themes and explore emerging ideas. Contributors examine organisms as different as unicellular algae and higher vertebrates, and consider defenses ranging from immune systems to protective changes in morphology, behavior, chemistry, and life history.
