Celebrity trainer and goop expert Lauren Roxburgh's program that uses pelvic floor strength to release stress, fortify the body, and treat the physical and mental origins of tension. Chances are your body feels some form of stress every day, whether it's inflammation, bloating, tension, discomfort, anxiety, or pain during sex. We're constantly distracted by ailments we can't quite seem to fix. Body alignment expert Lauren Roxburgh believes that all of these problems can be solved by first unlocking the foundation of your mental and physical health: the pelvic floor. Located at the root of our pelvis, it determines how firm our core is, how we handle stress, and how much energy reaches the rest of our body. Without addressing the health of our pelvic floor, we are all missing out on a powerful key component of our overall physical, emotional, and spiritual health. Roxburgh presents an entirely new approach to building well-being--one based on a strong pelvic floor, open energy channels, and a clear mind. The Power Source offers a deep understanding of how to cultivate this strength by following a holistic, multisensory program. Starting with the pelvic floor, Roxburgh focuses on the five power centers that can be harnessed throughout the body: The pelvic floor The deep core The upper core The heart and shoulders The head, neck, and jaw With targeted exercises to encourage healing movement, nourishing recipes--from a Confidence-Boosting Tonic to Root-Rejuvenating Bone Broth--and holistic therapies that include visualizations, aromatherapy, and more, Roxburgh gives a full toolbox to realign your body and your life.

Newnes has worked with Marty Brown, a leader in the field of power design to select the very best design-specific material from the Newnes portfolio. Marty selected material for its timelessness, its relevance to current power supply design needs, and its real-world approach to design issues. Special attention is given to switching power supplies and their design issues, including component selection, minimization of EMI, toroid selection, and breadboarding of designs. Emphasis is also placed on design strategies for power supplies, including case histories and design examples. This is a book that belongs on the workbench of every power supply designer!*Marty Brown, author and power supply design consultant, has personally selected all content for its relevance and usefulness*Covers best design practices for switching power supplies and power converters*Emphasis is on pragmatic solutions to commonly encountered design problems and tasks

The first systematic, quantitative appraisal of power density, offering detailed reviews of power densities of renewable energy flows, fossil fuels, and all common energy uses. “There's no author whose books I look forward to more than Vaclav Smil.” —Bill Gates In this book, Vaclav Smil argues that power density is a key determinant of the nature and dynamics of energy systems. Any understanding of complex energy systems must rely on quantitative measures of many fundamental variables. Power density—the rate of energy flux per unit of area—is an important but largely overlooked measure. Smil provides the first systematic, quantitative appraisal of power density, offering detailed reviews of the power densities of renewable energy flows, fossil fuels, thermal electricity generation, and all common energy uses. Smil shows that careful quantification, critical appraisals, and revealing comparisons of power densities make possible a deeper understanding of the ways we harness, convert, and use energies. Conscientious assessment of power densities, he argues, proves particularly revealing when contrasting the fossil fuel–based energy system with renewable energy conversions. Smil explains that modern civilization has evolved as a direct expression of the high power densities of fossil fuel extraction. He argues that our inevitable (and desirable) move to new energy arrangements involving conversions of lower-density renewable energy sources will require our society—currently dominated by megacities and concentrated industrial production—to undergo a profound spatial restructuring of its energy system.

A Note from Jill Briscoe Dear Friends, One paraphrase of 1 Peter 5:7 says, "You can throw the whole weight of your anxieties upon Him for you are His personal concern." Prayer and worry cannot live together. You cannot worry and pray at the same time. Prayer is the place to let your anxieties go--to hand them off to someone else, someone well able to carry them for you. God! It's hard to throw the whole weight of our anxiety upon Him isn't it? How do we do that? When I'm traveling, which seems to be constantly, I carry a briefcase full of files and books with me. It's heavy. When I'm on the road alone my back hurts by the end of the day. Often I'm with my husband, Stuart, or daughter, Judy, who hurry to take my briefcase to lift the load. I want to help so it's not an extra burden for them. Sometimes I say, "Let's both carry it. Let's share it." but the handle isn't big enough and it doesn't work. I've even been tempted to open the bag and take out some books to carry myself so it's lighter for them! But their backs are strong and well able to carry the case while my back is hurting, unable to carry it. So I throw my burden gratefully into their hands! They always smile at me because they love me and are concerned. Occasionally I refuse their kind offer of help. Why? For all sorts of reasons. I get to thinking they have their won burdens, and I should be able to carry a little briefcase filled with a few books. Or I begin to worry that they'll dread having me along because I'm such a nuisance with my moving library! I always reap the consequences of carrying the stuff myself, when guild, self-effort, pride, or stupidity lead me to refuse their helping hand. I'm sure Stuart and Judy consider me very foolish when they are walking right beside me and are willing and able to help, but I insist on going it alone. I think God thinks we are very foolish too when He has told us to hand off our heavy issues to Him and we don't. So don't forget. God is your constant travel companion along life's road. His back is big enough and strong enough for your caseload of worries. And don't be opening the bag and keeping a few books to carry yourself to make it easier on Him. Throw the whole weight of your anxieties upon Him for you are His personal concern. In His Love, Jill Briscoe For more information about Just Between Us resources, visit this page .

Safety of Lithium Batteries describes how best to assure safety during all phases of the life of Lithium ion batteries (production, transport, use, and disposal). About 5 billion Li-ion cells are produced each year, predominantly for use in consumer electronics. This book describes how the high-energy density and outstanding performance of Li-ion batteries will result in a large increase in the production of Li-ion cells for electric drive train vehicle (xEV) and battery energy storage (BES or EES) purposes. The high-energy density of Li battery systems comes with special hazards related to the materials employed in these systems. The manufacturers of cells and batteries have strongly reduced the hazard probability by a number of measures. However, absolute safety of the Li system is not given as multiple incidents in consumer electronics have shown. - Presents the relationship between chemical and structure material properties and cell safety - Relates cell and battery design to safety as well as system operation parameters to safety - Outlines the influences of abuses on safety and the relationship to battery testing - Explores the limitations for transport and storage of cells and batteries - Includes recycling, disposal and second use of lithium ion batteries
