Summary

Current-limiting fuses are widely used to protect the thyristors in dc drive systems. In the event of the commutation failure when regenerating (inverting), the fuses need to interrupt in loop supplied by the ac and dc voltages acting in series which is the most difficult case for protection by fuse.

In this paper, a detailed study of the complete interruption process has been investigated by modeling of arcing process of the fuse. The effect varying the motor time constant, supply impedance, number of fuses used to clear the fault and dc machine rating to the total response for fuses protecting against the regenerative circuit internal commutation fault has been studied. The model of 200A fuse is employed in this study and fuses in series with the semiconductor devices (F1) and fuses in ac line (F2) are both considered.

    Untamed - The Wildest Woman in...

    The inspiring biography of the adventuresome naturalist Carol Ruckdeschel and her crusade to save her island home from environmental disaster.   In a “moving homage . . . that artfully articulates the ferocities of nature and humanity,” biographer Will Harlan captures the larger-than-life story of biologist, naturalist, and ecological activist Carol Ruckdeschel, known to many as the wildest woman in America. She wrestles alligators, eats roadkill, rides horses bareback, and lives in a ramshackle cabin that she built by hand in an island wilderness. A combination of Henry David Thoreau and Jane Goodall, Carol is a self-taught scientist who has become a tireless defender of sea turtles on Cumberland Island, a national park off the coast of Georgia (Kirkus Reviews).   Cumberland, the country’s largest and most biologically diverse barrier island, is celebrated for its windswept dunes and feral horses. Steel magnate Thomas Carnegie once owned much of the island, and in recent years, Carnegie heirs and the National Park Service have clashed with Carol over the island’s future. What happens when a dirt-poor naturalist with only a high school diploma becomes an outspoken advocate on a celebrated but divisive island? Untamed is the story of an American original who fights for what she believes in, no matter the cost, “an environmental classic that belongs on the shelf alongside Carson, Leopold, Muir, and Thoreau” (Thomas Rain Crowe, author of Zoro’s Field: My Life in the Appalachian Woods).   “Vivid. . . . Ms. Ruckdeschel’s biography, and the way this wandering soul came to settle for so many decades on Cumberland Island, is big enough on its own, but Mr. Harlan hints at bigger questions.” —The Wall Street Journal   “Wild country produces wild people, who sometimes are just what’s needed to keep that wild cycle going. This is a memorable portrait.” —Bill McKibben, author of The End of Nature   “Deliciously engrossing. . . . Readers are in for a wild ride.” —The Citizen-Times

    The Outline of Science was written specifically with the man-on-the-street in mind as the target audience. Covering scientific subjects ranging from astronomy to biology to elementary physics in clear, concise and easily understood prose, this popular science work is largely as relevant today as when first published in 1922.In this third volume (of four), we learn about psychic science, the characteristics and interrelations of living creatures, as well as Botany, Biology, and Chemistry. Some chapters are devoted to the new applied sciences of electricity, telegraphy, and flying. (Summary adapted from the first and second volume by Availle.)

    Drought, forest fires, and melting ice caps: the climate crisis is an existential threat to human life on Earth. The Paris Climate Agreement shows that the actions of governments alone will not be enough to prevent a climate catastrophe.
    
    For Ferry Heilemann, digital entrepreneur and founder of the Leaders for Climate Action initiative, one thing is therefore very clear: businesspeople need to do their bit to contribute towards global climate protection. How can a business measure its own carbon footprint? How can CO² emissions be reduced in the shortest time possible? What specific steps are required to achieve this? And how can effective alliances be built up between businesses and their surroundings?
    
    With the aid of precise checklists, recommendations for practical action, and background knowledge, the Climate Action Guide shows how businesses can implement straightforward measures and make an important contribution to the protection of our planet – in the process also making themselves future-proof. The first action guide for businesses which want to take practical action to protect the climate.

    What started as a vision for the Olifants River Game Reserve [in South Africa] has become the story of a game ranger's life. With a naturalist's eye for detail as well as the bigger picture of managing a fragile ecosystem through years of drought and plenty, Mario Cesare brings a storyteller's delight - and a dash of Italian passion - to sharing his world. Life-and-death encounters with lion, elephant and buffalo are balanced by rescues and interventions as these giants of the lowveld suffer the effects of human interference in their ecosystem. There are problems with poachers and with rapacious neighbours; then the delights of success - and in the case of the elephant population, the conundrums of too much success. Mario Cesare's career has taken him from Timbavati and Mala Mala to Olifants River and beyond - and he delights in sharing his good fortune. His latest task: to develop and nurture the Olifants River Game Reserve as the fences of the Greater Kruger National Park area fall, undoing generations of damage. Man-eaters, Mambas and Marula Madness: A Game Rangers Life in the Lowveld provides a wealth of lessons on conservation as well as stories of life in the bush as it is enjoyed only by those fortunate enough to live on a 'Big Five' reserve.
