From #1 New York Times bestselling author Dr. Ian K. Smith, learn how to defy the effects of aging by implementing simple changes at every decade.
Whether we like it or not, lots of things change as we age: our joints start to creak, our muscles weaken, and we lose coordination. Our bodies simply don’t look or perform the same each decade of life, and our risks for various diseases and medical conditions also increase as the years do. Getting old may be inevitable, but feeling old is not: we can age well and maximize each decade of life if we do the right things at the right time.
In Eat Your Age, acclaimed doctor and bestselling author Ian K. Smith shows readers the steps they need to take in their 30s, 40s, 50s, and beyond to increase longevity and stave off future illnesses and ailments. By eating the right foods, keeping tabs on the right numbers, moving the right way, and sleeping better, we can slow the hands on the proverbial clock. Since food is medicine, this book will teach you what to eat at every age to prevent life-threatening diseases. For example:
30s—vitamin B6 (milk, ricotta cheese, tuna, eggs, sweet potato, bananas), magnesium (dark leafy greens, black beans, lentils, pumpkin seeds), Brussel sprouts, cauliflower40s—probiotic, plant-based milk, avocado, spinach, chickpeas50s—bromelain (pineapple, papaya, kiwifruit, asparagus, yogurt, sauerkraut), turmeric, berries, tomatoes, squash, carrots60s+—Omega-3 (fatty fish like salmon and mackerel as well as chia, flaxseed, edamame), vitamin B12 (clams, beef, fortified cereal, tuna, milk and dairy products, fortified nondairy products), probiotic, high fiber foods (pinto beans, acorn squash, collard greens, guava, strawberries, broccoli)With specific lifestyle and diet advice including fitness tests for each decade of life, this book proves that it’s never too late to start battling the aging process. With Dr. Smith’s sage plan, readers have the opportunity to function their best and find greater joy in life at any age.

Current concerns with climate change have resulted in greatly increased interest in power recovery from low grade heat sources. This includes both hot fluid streams which can be expanded directly to produce mechanical power and those which act as a source of heat to closed cycle power generation systems. Power recovery from low grate heat by means of screw expanders with a generalised overview of how best to recover power from such sources, based on thermodynamic considerations, which differs to the approach used in classical thermodynamics textbooks and which includes an introductory description of the types of working fluid that are used in systems used to recover power from such sources and the criteria that must be taken into account in their selection. This is followed by a description of the mathematical modelling of twin screw machine geometry. The modelling of the thermodynamics and fluid flow through such machines is then given, together with how this is used to predict their performance. Finally a detailed description is given of systems currently used or projected both for direct expansion of the source fluid and by recovery of heat from it, which includes those which are particularly suited to the use of screw expanders in place of turbines.
A novel generalised approach to the thermodynamics of power recovery from low grade heat systems Gives criteria for working fluid selection Provides details of, and how to model, screw expander geometry Details how to estimate screw expander performance Surveys types of system used for power recovery from low grade heat and where this can be improved by the use of screw expanders.234 kr
