The definitive, science-backed guide to cleaning everything in your home in a safe, sustainable, evidence-based way “A great reference for anyone stumped by reluctant-to-leave dirt—and far cheaper than hiring a professional.”—Booklist Countless cleaning hacks for every kind of household dirt may vie for our attention, but how do we know which ones really work and which ones will only leave you with a sticky mess that doesn’t actually do the job? Scientific evidence comes to the rescue, as chemistry professor Dario Bressanini teaches you everything worth knowing about cleaning agents and processes (and dispels plenty of myths, too). He answers all of our most pressing housekeeping questions: Is it more efficient to wash dishes in the sink or in the dishwasher? Does bleach remove dirt? Which cleaning supplies should I buy, and which can I make at home? Can vinegar and baking soda actually unclog your drain? How can I most effectively tackle different types of stains? What can get rid of that stuff on my showerhead? Bressanini covers subjects like these by digging into chemistry basics such as solubility, pH, and concentration, bringing them out of the classroom and into the real-world chores that we deal with every day. Laundry, dishes, sinks, bathtubs, counters, floors, and more—no matter what you’re cleaning, this book explains how to choose the right tools for the task, save yourself unnecessary effort, and stay eco-friendly by avoiding waste. The Science of Cleaning reminds us that science can be both useful and exciting. With Bressanini’s help, you can keep your home, your belongings, and yourself clean—with the confidence that only centuries of advancements in chemistry can provide.

This is a text book presenting the fundamentals of thermophotovoltaic(TPV) energy conversion suitable for an upper undergraduate or first year graduate course. In addition it can serve as a reference or design aid for engineers developing TPV systems. Each chapter includes a summary and concludes with a set of problems.The first chapter presents the electromagnetic theory and radiation transfer theory necessary to calculate the optical properties of the components in a TPV optical cavity. Using a simplified model, Chapter 2 develops expressions for the maximum efficiency and power density for an ideal TPV system. The next three chapters consider the three major components in a TPV system; the emitter, filter and photovoltaic(PV) array. Chapter 3 applies the electromagnetic theory and radiation transfer theory presented in Chapter 1 in the calculation of spectral emittance. From the spectral emittance the emitter efficiency is calculated. Chapter 4 discusses interference, plasma and resonant array filters plus an interference filter with an imbedded metallic layer, a combined interference-plasma filter and spectral control using a back surface reflector(BSR) on the PV array. The theory necessary to calculate the optical properties of these filters is presented. Chapter 5 presents the fundamentals of semiconductor PV cells. Using transport equations calculation of the current-voltage relation for a PV cell is carried out. Quantum efficiency, spectral response and the electrical equivalent circuit for a PV cell are introduced so that the PV cell efficiency and power output can be calculated.The final three chapters of the book consider the combination of the emitter, filter and PV array that make up the optical cavity of a TPV system. Chapter 6 applies radiation transfer theory to calculate the cavity efficiency of planar and cylindrical optical cavities. Also introduced in Chapter 6 are the overall TPV efficiency, thermal efficiency and PV efficiency. Leakage of radiation out of the optical cavity results in a significant loss in TPV efficiency. Chapter 7 considers that topic. The final chapter presents a model for a planar TPV system.Six appendices present background information necessary to carry out theoretical developments in the text. Two of the appendices include Mathematica programs for the spectral optical properties of multi-layer interference filters and a planar TPV system. Software is included for downloading all the programs within the book. - First text written on thermophotovoltaic(TPV) energy conversion - Includes all the necessary theory to calculate TPV system performance - Author has been doing TPV energy conversion research since 1980's - Emphasizes the fundamentals of TPV energy conversion - Includes a summary and problem set at the end of each chapter - Includes Mathematica programs for calculating optical properties of interference filters and planar TPV system performance solution software

A compassionate, shame-free guide for your darkest days “A one-of-a-kind book . . . to read for yourself or give to a struggling friend or loved one without the fear that depression and suicidal thoughts will be minimized, medicalized or over-spiritualized.”—Kay Warren, cofounder of Saddleback Church What happens when loving Jesus doesn’t cure you of depression, anxiety, or suicidal thoughts? You might be crushed by shame over your mental illness, only to be told by well-meaning Christians to “choose joy” and “pray more.” So you beg God to take away the pain, but nothing eases the ache inside. As darkness lingers and color drains from your world, you’re left wondering if God has abandoned you. You just want a way out. But there’s hope. In I Love Jesus, But I Want to Die, Sarah J. Robinson offers a healthy, practical, and shame-free guide for Christians struggling with mental illness. With unflinching honesty, Sarah shares her story of battling depression and fighting to stay alive despite toxic theology that made her afraid to seek help outside the church. Pairing her own story with scriptural insights, mental health research, and simple practices, Sarah helps you reconnect with the God who is present in our deepest anguish and discover that you are worth everything it takes to get better. Beautifully written and full of hard-won wisdom, I Love Jesus, But I Want to Die offers a path toward a rich, hope-filled life in Christ, even when healing doesn’t look like what you expect.

Now updated and expanded, a New York executive-turned-farmer shares his story and the hows & whys of running a small organic farm in 21st century America. Keith Stewart, already in his early forties and discontent with New York’s corporate grind, moved upstate and started a one-man organic farm in 1986. Today, having surmounted the seemingly endless challenges to succeeding as an organic farmer, Keith employs seven to eight seasonal interns and provides 100 varieties of fresh produce to the shoppers and chefs who flock twice weekly, May to December, to his stand at Union Square Greenmarket in Manhattan—the only place where his produce is sold. It’s a Long Road to a Tomato opens a window into the world of Keith’s Farm, with essays on Keith’s development as a farmer, the nuts and bolts of organic farming for an urban market, farm animals domestic and wild, and the political, social, and environmental issues relevant to agriculture today—and their impact on all of us. Includes a foreword by Deborah Madison and gorgeous new woodcuts by Flavia Bacarella Praise for It’s a Long Road to Tomato “Keith Stewart opens this engaging book by transforming himself abruptly from midlife executive into novice organic farmer. The twenty years that follow on an upstate New York farm are sampled here in true-life tales that—without denying the sometimes harsh realities of the small producer’s life—leave the reader in no doubt of the joys that keep this small farmer on the land.” —Joan Dye Gussow, author of This Organic Life “An enduring pleasure to read.” —Sally Schneider, author of A New Way to Cook “Stewart has been providing New Yorkers with magnificent vegetables for two decades. Now, as if to prove he can do anything, he provides all Americans with a compelling story about his own approach to farming. And at precisely the right moment, just as millions of people across the country are rediscovering the pleasure, and the importance, of eating close to home.” —Bill McKibben, author of Wandering Home and Falter
