  The Incredible Journey of Plants

  When we talk about migrations, we should study plants to understand that these phenomena are unstoppable. In the many different ways plants move, we can see the incessant action and drive to spread life that has led plants to colonize every possible environment on earth. The history of this relentless expansion is unknown to most people, but we can begin our exploration with these surprising tales, engagingly told by Stefano Mancuso. 
  Generation after generation, using spores, seeds, or any other means available, plants move in the world to conquer new spaces. The number and variety of tools through which seeds spread is astonishing: we have seeds dispersed by wind, by rolling on the ground, by animals, by water, or by a simple fall from the plant, which can happen thanks to propulsive mechanisms, the swaying of the mother plant, the drying of the fruit, and much more. 
  In this accessible, absorbing overview, Mancuso considers how plants convince animals to transport them around the world, and how some plants need particular animals to spread; how they have been able to grow in places so inaccessible and inhospitable as to remain isolated; how they resisted the atomic bomb and the Chernobyl disaster; how they are able to bring life to sterile islands; how they can travel through the ages, as they sail around the world.

  From an award-winning adventure and science journalist comes an eye-opening exploration of a burgeoning environmental phenomenon and the science coalescing around it. Leslie Anthony leads listeners on adventures physical and philosophical as he explores how and why invasive species are hijacking ecosystems around the globe. 
  Weaving science, travel, history, and humor with diverse examples to chart and describe the phases of species invasion and human response, Anthony introduces field researchers and managers who seek to understand the biological, social, and economic aspects of this complex issue, and whose work collectively suggests the emergence of a global shadow economy centered on invasives. 
  With tales of pythons in the Everglades, Asian carp and lamprey in the Great Lakes, Japanese knotweed seemingly everywhere, and the invasive organisms we don't see—pathogens and microbes such as the Zika virus—this book rivets attention on a new ecological reality.

  How do individuals decide whether to accept human causes of climate change, vaccinate their children against childhood diseases, or practice social distancing during a pandemic? Democracies depend on educated citizens who can make informed decisions for the benefit of their health and well-being, as well as their communities, nations, and planet. Understanding key psychological explanations for science denial and doubt can help provide a means for improving scientific literacy and understanding?critically important at a time when denial has become deadly. In Science Denial: Why It Happens and What to Do About It, the authors identify the problem and why it matters and offer tools for addressing it. This book explains both the importance of science education and its limitations, shows how science communicators may inadvertently contribute to the problem, and explains how the internet and social media foster misinformation and disinformation. The authors focus on key psychological constructs such as reasoning biases, social identity, epistemic cognition, and emotions and attitudes that limit or facilitate public understanding of science, and describe solutions for individuals, educators, science communicators, and policy makers. If you have ever wondered why science denial exists, want to know how to understand your own biases and those of others, and would like to address the problem, this book will provide the insights you are seeking.

  Introduction to Power System...

  Dr. Hidaia Mahmood Alassouli

  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.
