  An energy industry insider delivers hard truths about the reality of fracking. Conventional wisdom has North America entering a new era of energy abundance thanks to shale gas. But has industry been honest? Cold, Hungry and in the Dark argues that declining productivity combined with increasing demand will trigger a crisis that will cause prices to skyrocket, damage the economy, and have a profound impact on the lives of nearly every North American. Relying on faulty science, bought-and-paid-for-white papers masquerading as independent research and “industry consultants,” the “shale promoters” have vastly overstated the viable supply of shale gas resources for their own financial gain. This startling exposé, written by an industry insider, suggests that the stakes involved in the Enron scandal might seem like lunch money in comparison to the bursting of the natural gas bubble. Exhaustively researched and rigorously documented, Cold, Hungry and in the Dark:·       Puts supply-and-demand trends under a microscope·       Provides overwhelming evidence of the absurdity of the one hundred-year supply myth·       Suggests numerous ways to mitigate the upcoming natural gas price spike The mainstream media has told us that natural gas will be cheap and plentiful for decades, when nothing could be further from the truth. Forewarned is forearmed. Cold, Hungry and in the Dark is vital reading for anyone concerned about the inevitable economic impact of our uncertain energy future.“Powers’s step-by-step dismantling of the abundance myth ought to alarm policymakers, corporate managers, investors, business owners, and concerned citizens alike.”—Kurt Cobb, author of Prelude and contributor to The Christian Science Monitor

  Introduction to Power System...

  Power system protection systems have three basic components: Instrument transformers, Relays, Circuit breakers
  
  The function of the CT is to reproduce in its secondary winding a current I' that is proportional to the primary current I. The CT converts primary currents in the kiloamp range to secondary currents in the 0–5 ampere range for convenience of measurement.
  
  The function of the relay is to discriminate between normal operation and fault conditions. The OC relay in Figure 2 has an operating coil, which is connected to the CT secondary winding, and a set of contacts. When |I'| exceeds a specified ''pickup'' value, the operating coil causes the normally open contacts to close. When the relay contacts close, the trip coil of the circuit breaker is energized, which then causes the circuit breaker to open.
  
  System-protection components have the following design criteria:
  • Reliability: Operate dependably when fault conditions occur, even after remaining idle for months or years. Failure to do so may result in costly damages.
  • Selectivity: Avoid unnecessary, false trips.
  • Speed: Operate rapidly to minimize fault duration and equipment damage. Any intentional time delays should be precise.
  • Economy: Provide maximum protection at minimum cost.
  • Simplicity: Minimize protection equipment and circuitry.
  
  Since it is impossible to satisfy all these criteria simultaneously, compromises must be made in system protection.
  
  The book consists from the following sections:
  1. Chapter 1: Power System Faults:
  2. Chapter 2: Instrument Transformers.
  3. Chapter 3: Overcurrent and Earth Fault Protection Relays.
  4. Chapter 4: Radial System Protection.
  5. Chapter 5: Zones of Protection.
  6. Chapter 6: Differential Relays.
  7. Chapter 7: Distance Relays.
  8. Chapter 8: Transformer Protection.
  9. Chapter 9: Generator Protection.
  10. Chapter 10: Busbar Protection.
  11. Chapter 11: Circuit Breakers.
  12. Chapter 12: Fuses.
  13. Chapter 13: References.

  World Hunger - 10 Myths

  “The definitive solutions-based book for all those questioning why hunger still exists when there is such an abundance of food.” —The Huffington Post, “Food Tank’s 2015 Recommended Fall Reading List”   From bestselling authors Frances Moore Lappé and Joseph Collins comes the twenty-first century’s authoritative book on world hunger. Lappé and Collins refute the myths that prevent us from addressing the root causes of hunger across the globe. World Hunger: 10 Myths draws on extensive new research to offer fresh, often startling, insights about tough questions—from climate change and population growth to genetically modified organisms (GMOs) and the role of US foreign aid, and more.   Brimming with little-known but life-changing examples of solutions to hunger worldwide, this myth-busting book argues that sustainable agriculture can feed the world, that we can end nutritional deprivation affecting one-quarter of the world’s people, and that most in the Global North have more in common with hungry people than they thought. For novices and scholars alike, World Hunger: 10 Myths will inspire a whole new generation of hunger-fighters.   “World Hunger . . . should become not only a book for study, but a guide to action.” —Noam Chomsky

  Chrysalis - Maria Sibylla Merian...

  Before Darwin, before Audubon, there was Maria Sibylla Merian. 
  An artist turned naturalist, Merian was born just 16 years after Galileo proclaimed that the Earth orbited the sun. But at the age of 50, she sailed from Europe to South America on a solo scientific expedition to study insect metamorphosis—an unheard-of journey for any naturalist at that time, much less a woman. 
  When she returned, she produced a book that secured her reputation, only to have it savaged in the 19th century by scientists who disdained the work of “amateurs.” 
  Chrysalis takes us from golden age Amsterdam to the Surinam tropics to modern laboratories where Merian’s insights fuel a new branch of biology. The New Yorker called it a "spellbinding biography." In it, Kim Todd brings to life a 17th century woman whose boldness and vision would still be exceptional today.

  What Do Animals Think and Feel?

  In What Do Animals Think and Feel?, the biologist Karsten Brensing has something astonishing to tell us about the animal kingdom: namely that animals, by any reasonable assessment, have developed the sophisticated systems of social organization and behaviour that human beings call 'culture'. Dolphins call one another by name and orcas inhabit a culture that is over 700,000 years old. Chimpanzees wage strategic warfare, while bonobos delight in dirty talk. Ravens enjoy snowboarding on snow-covered roofs, and snails like to spin on hamster exercise wheels. Humped-back whales follow the dictates of fashion and rats are dedicated party animals. Ants recognize themselves in mirrors and spruce themselves up before they return home. Ducklings can pass complicated tests in abstract thinking. Dogs punish disloyalty, though they are also capable of forgiveness if you apologize to them. Brensing draws on the latest scientific findings as well as his own experience working with animals, to reveal a world of behavioural and cognitive sophistication that is remarkable similar to our own.
