Vanity, Vitality, and Virility: The Science behind the Products You Love to Buy - PDF
نویسندگان: خلاصه: What is the secret of shower cleaners? How does the dangerous explosive nitroglycerin ward off heart attacks? And what medicines, usually prescribed for other purposes, are said to produce the ultimate orgasm? In Vanity, Vitality, and Virility, award-winning science writer John Emsley offers a fascinating behind-the-scenes account of 30 chemicals that we use everyday to make ourselves more beautiful, to improve our diet and sexual pleasure, to kill germs, and to ward off depression and other mental illnesses. Emsley looks at common compounds such as alpha-hydroxy acids, vitamin C, chlorine bleach, and Prozac, telling us if they work, how they work, and how they were discovered. Indeed, the book is packed with useful information and easy-to-digest science, and Emsley relates it all with a light touch that delights in the odd fact or amusing anecdote. Thus we learn of the "vitamin C tights" sold in Japan to make your legs more beautiful (they don't work) and of the whimsical Hungarian scientist who first isolated vitamin C and wanted to name it "godnose"--because he had no idea what the compound was. We discover that Cleopatra was right to bath in milk, which is filled with alpha-hydroxy acids. And we read about the unforgettable British researcher who demonstrated a powerful new drug for male erections at a Las Vegas convention--injecting himself with the compound and then "displaying the results" to a stunned lecture hall. As with the much-loved Nature's Building Blocks, in John Emsley's hands, chemistry comes alive. Anyone curious about the ingredients in the products we use, and everyone fascinated with science, will be enthralled by this book.

نویسندگان: خلاصه: The tape isn't clear. When you said the two civilizations could economically exchange theirbyproducts, which words did you use to the nice human scientist?" Tima poised her pen over hernotes, her doggy face earnest and studious. "Did you say, Interchange, exchange, trade,mutually-consume, mutually-eat or ingest or input? And did you say byproducts, reject products,surplus, waste, excretion, excrement or shit?"Her husband, hanging upside down from the exercise bar, shrugged. "I don't remember. Someword for harmonic mutual aid or intercourse. Scientists focus on concepts. It doesn't matter whatwords I used.""It matters," she kissed the air in his direction. "You did a perfect study of the culture, yourdiplomacy was wonderful. This report must be complete in every detail. I want you to get thecredit you deserve." She resumed her note taking, listening through earphones to their recordingsof their strangely unsuccessful attempt to open an embassy on the planet Earth, in which theyalmost lost their lives

Running from Injury: Why runners get injured and how to stop it Kindle Edition - Original PDF
نویسندگان: خلاصه: Peter Francis saw his teenage years transformed by a miracle drug called running. His elation was soon followed by despair, in the form of 12-years of repetitive injuries. Spurred on by personal injustice, Peter pursued 3-science degrees, multiple coaching and consultancy roles before making a breakthrough in the form of what had seemed like an unlikely comeback. In 2016 aged 29-years, for the first time in his life, he ran for almost 3-years uninterrupted. This period coincided with running multiple personal bests (33:46 10-km; 78:00 half marathon). In this book, he uses a combination of his own story and his learnings spanning some 18-years of trial and error to provide a holistic explanation for why runners get injured and how best to avoid it. His personal story is as captivating as the information it imparts. Whether you are a disgruntled beginner or an Olympic hopeful, you cannot help but become more consistent having read this book.
Monday Morning Mentoring: Ten Lessons to Guide You Up the Ladder - PDF
نویسندگان: خلاصه: It was a rainy, gloomy day when I left home for my firstmeeting with Tony.Frankly, I was somewhat cynical about whether meet-ing with Tony would change anything at work. At best, timewith Tony would probably make me feel better about howthings were going. I guess I really doubted he could do muchto change how I managed. After all, I had worked for yearsfor one of the best companies in the world and had been tonumerous management-development sessions. To no one’ssurprise, however, the impact of these highly touted trainingsessions rarely lasted more than a short time.I had to keep reminding myself that if things were great,I never would have called Tony in the first place. The truth wasthis: I was at a crossroads in my career. Deep down I knewsomething was going to have to change, one way or another.“Get with it,” I chided myself. “Executives all over the country
This Is Where I Leave You: A Novel - PDF
نویسندگان: خلاصه: Dad’s dead,” Wendy says offhandedly, like it’s happened before, likeit happens every day. It can be grating, this act of hers, to be utterly unfazed at all times, even in the face of tragedy. “He died two hoursago.”“How’s Mom doing?”“She’s Mom, you know? She wanted to know how much to tip thecoroner.”I have to smile, even as I chafe, as always, at our family’s patentedinability to express emotion during watershed events. There is no occasion calling for sincerity that the Foxman family won’t quickly diminishor pervert through our own genetically engineered brand of irony andevasion. We banter, quip, and insult our way through birthdays, holidays, weddings, illnesses. Now Dad is dead and Wendy is cracking wise.It serves him right, since he was something of a pioneer at the forefrontof emotional repression.“It gets better,” Wendy says.“Better? Jesus, Wendy, do you hear yourself?”“Okay, that came out wrong.”“You think?”“He asked us to sit shiva.”“Who did?”“Who are we talking about? Dad! Dad wanted us to sit shiva.”2 J o n a t h a n Tr o p p e r“Dad’s dead.”Wendy sighs, like it’s positively exhausting having to navigate thedense forest of my obtuseness. “Yes, apparently, that’s the optimal timeto do it.”“But Dad’s an atheist.”“Dad was an atheist.”“You’re telling me he found God before he died?”“No, I’m telling you he’s dead and you should conjugate your tensesaccordingly.......
If You Eat, You Never Die: Chicago Tales - PDF
نویسندگان: خلاصه: Food was religion in our house. In her tortured English, Mamaalways said, “If you eat, you never die,” which to me simply meantthat dead people no longer eat, but it seemed to make perfect senseto her. Why did I imagine that I could hide the weight I was cuttingfor the wrestling team?The first seven or eight pounds were easy. The weight came offmostly from my stomach and the lower part of my chest where theribs pushed through, and I was able to hide it with bulky sweatersand baggy sweatshirts. After ten or fifteen pounds, my face becamemore angular and bony, my eyes two hollow sockets, my lips dry andcracked. Then she knew.I sat there at the dining room table on a Friday night, 106 pounds,21 pounds under my normal weight. Mama clomped from the kitchento the dining room carrying dishes full of food, her flat, heavy foot-steps shaking the house. Every time she set something down, she eyedmy plate with anger.
Writing in the Devil's Tongue: A History of English Composition in China - PDF
نویسندگان: خلاصه: Asense of complacency, if not outright chauvinism, is tangible these daysin certain parts of American composition studies. Sensational state-ments of one kind or another—“Composition Studies Saves the World!”;“Globalizing Composition”; “Transnationalizing/Globalizing Rhetoric andComposition Studies”; and so forth—reveal not only tremendous disciplin-ary pride but also compositionists’ confidence in what the discipline cando: namely, rescue the troubled world at large.1 And why shouldn’t we beconfident about what the discipline can achieve? After all, we have gaineda better understanding of our students, students of diverse linguistic, cul-tural, racial, sexual, and class backgrounds who have made such a strongpresence in American universities since the 1960s; and we have developedeffective pedagogical approaches to address those students’ needs. Project-ing this national experience to the rest of the globe, we naturally becomeoptimistic. Indeed, the rest of the world is also hopeful now, looking toAmerican composition studies for standards of English writing practicesand proven pedagogies.As the teaching of composition is increasingly connected to global po-litico-economic dynamics, our disciplinary effort to lift composition out ofnarrow nation-state bounds is the right direction to go. However, Americancomposition scholars do not seem fully cognizant of the geopolitical differ-ences and stakes involved in the teaching of English writing. For one thing,while English has been taught as the native language, the official language,or a second language in the United States, it is typically taught as a foreignlanguage in the majority of nations in the world. A different name for Englishentails a different history of the language in a particular country. A differ-ent name for English entails a whole different constellation of values andpractices in teaching English writingآیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
