A fascinating study that “opens a window on the world of beekeeping and female beekeepers” (Lexington Herald-Leader). From Africa to Australia to Asia, women have participated in the pragmatic aspects of honey hunting and in the more advanced skills associated with beekeeping as hive technology has progressed through the centuries. Who are the women who keep bees and what can we learn from them? Beeconomy examines the fascinating evolution of the relationship between women and bees around the world. Bee expert Tammy Horn profiles female beekeepers, describing their work and how they manage it; the sense of community they enjoy; how beekeeping is relevant to questions about globalization and politics—and how it provides an opportunity for a new sustainable economy, one that takes into consideration environment, children, and family needs.Zum Buch
Every NASCAR fan—at one time or another—asks the same question: Why isn't my favorite driver winning? This is your chance to discover how much more there is to NASCAR than "Go fast, turn left, and don't crash." If you've ever wondered why race cars don't have mufflers, how "bump drafting" works, or what in the world "Let's go up a pound on the right rear and add half a round of wedge" means, The Physics of NASCAR is for you.In this fast-paced investigation into the adrenaline-pumping world of NASCAR, a physicist with a passion uncovers what happens when the rubber hits the road and 800-horsepower vehicles compete at 190 miles per hour only inches from one another.Diandra Leslie-Pelecky tells her story in terms anyone who drives a car—and maybe occasionally looks under the hood—can understand. How do drivers walk away from serious crashes? How can two cars travel faster together than either car can on its own? How do you dress for a 1800°F gasoline fire? In simple yet detailed, high-octane prose, this is the ultimate thrill ride for armchair speed demons, auto science buffs, and NASCAR fans at every level of interest.Listeners, start your engines.Zum Buch
Have you ever stopped to wonder how life has been for the people who have been on the frontline of fighting Covid-19 – their experiences, how they are treated, how they are able to cope with the extreme pressure, seeing death everywhere, and risking being infected all the time? And have you wondered why nurses would be threatening to strike and others even strike in the middle of the pandemic to get a full glimpse of what has really been going on but has gone unreported? If you’ve answered YES, keep reading...You Are About to Step into a Frontline Nurse’s World For A Moment, To Get A Glimpse Of Just How This Pandemic Has Been Brutal For The Frontline Nurses All Over The World! The pandemic has been brutal for nurses and other frontline workers. With nurses always dealing with Covid-19 cases every single day, seeing patients in thousands develop moderate to severe symptoms and others dying of Covid-19 related complications, you can agree with me that nurses have really seen the pandemic from a completely different perspective compared to everyone else. And this perspective hasn’t been one that anyone ‘outside’ could ever imagine. From extremely long working hours, the scare of getting infected with Covid-19 to the trauma of seeing disease, sickness, and death everywhere to mistreatment by company representatives to being not welcomed by locals, to someone on the outside, the details in this book will literally make you wonder whether what’s in this book is really true. Written by one of the many traveling nurses who has been to several states and seen it all, from New York to the Mexican border to Illinois and Texas, her account of her experiences in her line of duty will leave you with a new perspective about so many things about the pandemic.Zum Buch
Librivox volunteers bring you 12 readings of Oh! Where Do the Fairies Hide Their heads by Thomas Haynes Bayly. Oh! Where do the fairies hide their heads,When snow lies on the hills,When frost has spoiled their mossy beds,And crystallized their Rills?Beneath the moon they cannot tripIn circles o’er the plain;And draughts of dew they cannot sip,Till green leaves come again.This was the weekly poetry project for February 15, 2015.Zum Buch
Faults studies form an important part of power system analysis. The problem consists of determining bus voltages and line currents during various types of faults. If the fault location is known the problem can be easily solved. But if the fault location is unknown, it is difficult to solve the problem. If the fault location is known the problem can be easily solved. But if the fault location is unknown, it is difficult to solve the problem. There were attempts to find the critical distance of a fault that will cause certain per-defined voltage dip at certain bus, and the problem was easy to be solved in radial systems, but yet non of the existing researches could provide proper solution for finding the critical distance of the fault at certain line that will cause predefined voltage dip magnitude at certain bus in meshed power system. The paper provided proper solution based in Gauess Seidal to find the critical distance in meshed power systemZum Buch
New research indicates that crows are among the brightest animals in the world. And professor of Wildlife Science at the University of Washington John Marzluff has done some of the most extraordinary research on crows, which has been featured in The New York Times, National Geographic, and the Chicago Tribune, as well as on NPR and PBS. Now he teams up with artist and fellow naturalist Tony Angell to offer an in-depth look at these incredible creatures—in a book that is brimming with surprises. Redefining the notion of "bird brain," crows and ravens are often called feathered apes because of their clever tool-making and their ability to respond to environmental challenges, including those posed by humans. Indeed, their long lives, social habits, and large complex brains allow them to observe and learn from us and our social gatherings. Their marvelous brains allow crows to think, plan, and reconsider their actions. In these and other enthralling revelations, Marzluff and Angell portray creatures that are nothing short of amazing: they play, bestow gifts on people who help or feed them, use cars as nutcrackers, seek revenge on animals that harass them, are tricksters that lure birds to their deaths, and dream. The authors marvel at crows' behavior that we humans would find strangely familiar, from delinquency and risk taking to passion and frolic. A testament to years of painstaking research, this riveting work is a thrilling look at one of nature's most wondrous creatures.Zum Buch
