  Dark Forces - The Power of...

  Dark forces, often referred to as unseen energies, are the invisible yet powerful forces that can influence our lives, environments, and even the very fabric of the universe. These forces have been a part of human consciousness for centuries, often portrayed in folklore, religion, and mythology. Despite their mysterious nature, dark forces are believed to be an integral aspect of the universe’s energy system. Understanding these forces is not just about acknowledging their existence but also comprehending their role in shaping our physical and psychological experiences. 
  The concept of dark forces can be traced back to ancient civilizations, where they were often associated with spirits, deities, or unseen powers that governed the natural world. In many cultures, these forces were believed to have both a destructive and protective power, often associated with night, the unknown, or the unconscious. Over time, these interpretations evolved, but the central idea remained the same: dark forces were unseen, mysterious, and influential. 
  In modern times, dark forces are understood through the lens of energy dynamics. The idea that everything in the universe is made up of energy is now widely accepted in scientific circles. This energy, however, is not always visible or detectable through conventional means. It is this unseen aspect of energy that gives rise to the concept of dark forces. These forces are believed to operate in the background, influencing our environments and experiences in ways we may not immediately perceive.

  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.

  Why Not Better and Cheaper? -...

  An engaging account of innovation in healthcare and why the results fall short for patients and society. 
   
   
   
  The evolution of the cell phones we carry in our pockets demonstrates that quality can increase while prices fall. Why doesn't healthcare also get better and cheaper? 
   
   
   
  In Why Not Better and Cheaper?, James B. Rebitzer and Robert S. Rebitzer offer an answer to this question. Bringing together research on incentives, social norms, and market competition, they argue that the healthcare system generates the wrong kinds of innovation. It is too easy to profit from low-value innovations and too hard to profit from innovations that reduce the costs of care. The result is a healthcare system that is profusely innovative yet remarkably ineffective in discovering ways to deliver increased value at lower cost. 
   
   
   
  Why Not Better and Cheaper? sheds new light on the trajectory of innovation in healthcare, and how to point innovation in a better direction.

  Renowned by law enforcement and clinical mental health experts nationwide, Delete Me: D.S.M. 7 Steps to Social Media Abstinence, was formerly only circulated through DRUGFR33.ORG.  
  Swipe left. It's time to delete the social media disease. There are currently no specialized treatments for social media addiction and anxiety type conditions attributed to social media usage. Whereas most "remedies" for social media abuse call for "vacations", "breaks", and "parental surveillance" from the applications, Delete Me refutes these methods as ineffective. Fortune 500 IT consultant & engineer turned clinical mental health researcher & crisis intervention counselor, J.A. Thomas insists that we’re far better off abstaining from the applications altogether. J.A. Thomas, MSW, who is one of a growing army of industry experts going offline, offers powerful and personal reasons for all of us to abandon these treacherous online platforms. J.A. Thomas left a lucrative career in Big Tech in pursuit of investigating online crime with law enforcement. Now a critical crisis intervention counselor, Thomas hopes to foster transparent public health information surrounding the dangers of social media usage and its links to severe mental health conditions and the illicit online sex & drug trades. The methodologies introduced in D.S.M. 7 insist in total abstinence from all social media applications as key to driving us towards richer and more meaningful ways of living by connecting us back to the world beyond the tiny blue screen. 
  "Educational, engaging and life saving! J.A.Thomas sounds the alarm on the coercive and destructive force that is big social. This book will help you change your life for the better and allow you to proudly proclaim ... I'm offline." 
  -Dr. J. S. Kastendiek | M.D. Clinical Psychiatry 
  "This deserves the attention of all parents."

  The Common Uncommon - A Forest...

  From the renowned author of A Year in the Maine Woods, the intimate, thoughtful reflections of a lifetime spent observing the natural world. 
   
  For forty years, Bernd Heinrich has been ensconced in the woods of the northern, or boreal, forest, a vast sea of spruce, fir, and larch in the mountains of western Maine. All life confronts vast and occasionally rapid environmental changes, as one day, and one season, is to the next a completely different environment. Heinrich's narrative illuminates the complete experience of his seasonal life―with the ups and downs of not just the leaves and snow, but also the problems, solutions, and frustrations of unblinking immersion in nature. He observes the "common uncommon" of spiders, ants, chestnut trees, porcupines, owls, and mice as his story branches out into five themes: Being, Becoming, Interbeing, Remembering, and Returning. The Common Uncommon is a narrative of small surprises in nature, some delightful and some―brought on by climate change―devastating, all seen through the sharp eye of a world–renowned naturalist.
