New results are presented for inviscid, supersonic and hypersonic blunt-body flow fields obtained with a numerical time-dependent method patterned after that of Moretti and Abbett. In addition, important comments are made with regard to the physical and numerical nature of the method. Specifically, numerical results are presented for two-dimensional and axisymmetric parabolic and cubic blunt bodies as well as blunted wedges and cones; these results are presented for zero degrees angle of attack and for a calorically perfect gas with gamma = 1.4. The numerical results are compared with other existing theoretical and experimental data. Also, the effects of initial conditions and boundary conditions are systematically examined with regard to the convergence of the time-dependent numerical solutions, and the point is made that the initial conditions can not be completely arbitrary. Finally, in order to learn more about the performance of the time-dependent method, a numerical experiment is conducted to examine the unsteady propagation and region of influence of a slight pressure disturbance introduced at a point on the surface of a blunt body.

From the authors of the bestselling ChiRunning comes a revolutionary program that blends the health benefits of walking with the core principles of T’ai Chi to deliver maximum physical, mental, and spiritual fitness. The low-impact health benefits of walking have made it one of the most popular forms of daily exercise. Yet few people experience all the benefits that walking can offer. In ChiWalking, Danny and Katherine Dreyer, well-known walking and running coaches, teach the walking technique they created that transforms walking from a mundane means of locomotion into an intensely rewarding practice that enhances mental, emotional, and physical well-being. Similar to Pilates, yoga, and T’ai Chi, ChiWalking emphasizes body alignment and mindfulness while strengthening the core muscles of the body. The five mindful steps of the ChiWalking program will get anyone, regardless of age or athletic ability, into great shape from head to toe, inside and out. 1. Get aligned. Develop great posture and better balance. 2. Engage your core. Make back and knee pain disappear. 3. Create balance. Walk faster, farther, and with less effort. 4. Make a choice. Choose from a menu of twelve great walks such as the Cardio Walk, the Energizing Walk, or the Walking Meditation, to keep your exercise program fresh. 5. Move forward. Make walking any distance a mindful, enjoyable experience, whether you’re a beginner or a seasoned walker.

Harness the principles of synchronicity and flow to live better, work smarter, and find purpose in your life When we align with circumstance, circumstance aligns with us. Using a cutting-edge scientific theory of synchronicity, Sky Nelson-Isaacs presents a model for living "in the flow"--a state of optimal functioning, creative thinking, and seemingly effortless productivity. Nelson-Isaacs explains how our choices create meaning, translating current and original ideas from theoretical physics and quantum mechanics into accessible, actionable steps that we can all take to live lives in better alignment with who we are and who we want to be. By turns encouraging and empowering, Living in Flow helps us develop an informed relationship to meaning-making and purposefulness in our lives. From this we can align ourselves more effectively within our personal, professional, and community relationships to live more in flow.

Tribology is emerging from the realm of steam engines and crank-case lubricants and becoming key to vital new technologies such as nanotechnology and MEMS. Wear is an integral part of tribology, and an effective understanding and appreciation of wear is essential in order to achieve the reliable and efficient operation of almost any machine or device. Knowledge in the field has increased considerably over recent years, and continues to expand: this book is intended to stimulate its readers to contribute towards the progress of this fascinating subject that relates to most of the known disciplines in physical science. Wear – Materials, Mechanisms and Practice provides the reader with a unique insight into our current understanding of wear, based on the contributions of numerous internationally acclaimed specialists in the field. Offers a comprehensive review of current knowledge in the field of wear. Discusses latest topics in wear mechanism classification. Includes coverage of a wide variety of materials such as metals, polymers, polymer composites, diamonds, and diamond-like films and ceramics. Discusses the chemo-mechanical linkages that control tribology, providing a more complete treatment of the subject than just the conventional mechanical treatments. Illustrated throughout with carefully compiled diagrams that provide a unique insight into the controlling mechanisms of tribology. The state of the art research on wear and the mechanisms of wear featured will be of interest to post-graduate students and lecturers in engineering, materials science and chemistry. The practical applications discussed will appeal to practitioners across virtually all sectors of engineering and industry including electronic, mechanical and electrical, quality and reliability and design.
