Excitable media comprise a class of models for a wide range of physical, chemical, and biological systems that exhibit spontaneous formation of spatial patterns. Patterns in Excitable Media: Genesis, Dynamics, and Control explores several aspects of the dynamics of such patterns—in particular their evolution upon interaction with structural and functional heterogeneities in the system. The book provides readers with an introduction to recent developments in the interdisciplinary field of dynamics and control of patterns in nonlinear biological systems described by excitable media models. It also discusses low-amplitude control schemes for eliminating such patterns from an excitable medium which has direct clinical relevance in view of the close connection to life-threatening cardiac arrhythmia.

Separation processes are challenging steps in any process industry for isolation of products and recycling of reactants. Membrane technology has shown immense potential in separation of liquid and gaseous mixtures, effluent treatment, drinking water purification and solvent recovery. It has found endless popularity and wide acceptance for its small footprint, higher selectivity, scalability, energy saving capability and inherent ease of integration into other unit operations. There are many situations where the target component cannot be separated by distillation, liquid extraction, and evaporation. The different membrane processes such as pervaporation, vapor permeation and membrane distillation could be used for solving such industrial bottlenecks. This book covers the entire array of fundamental aspects, membrane synthesis and applications in the chemical process industries (CPI). It also includes various applications of pervaporation, vapor permeation and membrane distillation in industrially and socially relevant problems including separation of azeotropic mixtures, close-boiling compounds, organic–organic mixtures, effluent treatment along with brackish and seawater desalination, and many others. These processes can also be applied for extraction of small quantities of value-added compounds such as flavors and fragrances and selective removal of hazardous impurities, viz., volatile organic compounds (VOCs) such as vinyl chloride, benzene, ethyl benzene and toluene from industrial effluents. Including case studies, this is a must-have for any process or chemical engineer working in the industry today. Also valuable as a learning tool, students and professors in chemical engineering, chemistry, and process engineering will benefit greatly from the groundbreaking new processes and technologies described in the volume.

Winning Without Waging War – the mother of all strategies. Winning Without Waging War (WWWW) are war tactics for the business and career battlefields. In this book, hidden secrets taught by the masters and gurus of Zen methods, magic mantras realized by the author, an exponent of the art of business war, while facing challenging business and career environments are REVEALED. This book is the convergence of four different arts—Know your Enemy, Know Yourself, Know your Terrain (Situations), Know your Divinity. It is written as a workbook for easy practice to obtain an exponential benefit. This book facilitates the identification of one’s business enemy in the market or career enemy within the corporate. It grooms professionals in playing offence and defence games applying deception techniques for surprise attacks to ensure unprecedented success in their work life. Some powerful techniques taught in this book include: How to become a leader right from day one? How a start-up can take on mammoth organizations? How an ignored professional can shoot into prominence by leveraging organizational politics? Overwhelming an interview panel to get that all-important job, using signalling techniques to get others to see your way, repositioning techniques for gaining a competitive edge in the market, Super Stretch Target setting, Divine Creative processes 1-2-3, and Tao leadership traits like being invisible but illuminating others are largely unknown to the world. This book not only explains these concepts in simple ways using illustrative case studies, but it also provides concrete action plans for effective application.
