A fast-paced and action-packed dystopian novel, addressing the nature of power, the limits of rationality, and the dominance of fear. In a world on the brink of totalitarian rule, one man rises from the shadows to ignite a revolution and becomes the unlikely leader of a war of resistance that will shake the very foundations of power. General Firebrand, an unsocial and recovered alcoholic, considered a pariah by society, rises up against the country's fascist regime. In this guerrilla war, Firebrand garners support from the unlikeliest allies. Beasts and birds of the jungle join the struggle. Spirits of historical figures from past wars and fictional characters with supernatural abilities lend their strength to the cause. As a devastating secret is revealed that moves Firebrand to the core, the battle for liberation takes on new dimensions, exposing the fragility of rationality and the weight of historical wrongs committed in the name of a supposedly humane ideology.   With zany, irreverent prose and a breakneck pace, General Firebrand and His Red Atlas is an explosive debut novel that challenges conventional wisdom and explores the complexities of courage, doubt, and the pursuit of justice in a world dominated by fear.

The discrete element method (DEM) is considered the gold standard for simulating particle flows. In this book, DEM is employed to investigate the mixing and segregation of granular material in various prototypical solid handling devices commonly found in process industries. Recently, it has been suggested that segregation in particle mixers can be thwarted if the particle flow is inverted at a rate above a critical forcing frequency. Based on the above hypothesis, various configurations of solid mixers (rotating drums) are numerically and experimentally studied to investigate the conditions for improved mixing. In addition, an experimentally validated DEM model is used to find the critical chute length for segregation based on the above hypothesis of time modulation. While segregation is often an undesired effect, sometimes separating the components of a particle mixture is the ultimate goal. Here, two examples of novel rate-based separation devices are demonstrated that have the potential to revolutionize the way particles are separated today across many industries by providing an alternate ¿energy efficient¿ and ¿green¿ means of performing this economically important task.
