  A 36‑lecture audio course on the materials that run the modern world—from ore bodies and brines to magnets, batteries, chips, and reactors. Each lecture focuses on one element or mineral, tracing its journey from deposit geology through beneficiation and refining to the devices it powers. 
  We make the flowsheet legible: comminution and flotation; roasting, high‑pressure acid leaching, solvent extraction, and ion exchange; separation to oxides and metals; alloying and specialty powders. See how neodymium‑iron‑boron magnets are born, why lithium hexafluorophosphate matters in electrolytes, where gallium nitride wins in power, how graphite anodes evolve with silicon, and how the uranium fuel cycle and vanadium flow batteries actually work. 
  Markets and politics are treated as engineering constraints. Learn to spot yield killers, read offtake agreements, and separate strategic scarcity from narrative. Test real substitutions—ferrites in small motors, sodium‑ion for short‑range storage, gallium nitride versus silicon carbide—and where performance cliffs block redesign. We map chokepoints beyond the mine: separation capacity, reagents, waste handling, water and energy intensity, and manufacturer qualification cycles. Then we follow the consequences—export controls and quotas, permitting and community consent, tariffs and friend‑shoring, standards and labeling rules. 
  Rigorous, narrative‑driven, and built for the intellectually ambitious, this course is an operator’s guide to the science, supply chains, and statecraft of a materials‑constrained century.

  Environmental Justice - A Very...

  Environmental justice recognizes that environmental benefits and burdens should be distributed fairly, and that the people making policy decisions should incorporate the views of those most often harmed: people of color, Indigenous populations, low-income communities, and those who are underserved and disenfranchised for other reasons such as age, gender, or disability. It encompasses not only traditional environmental issues like clean air and clean water, but also social issues such as employment, nutrition, and access to health care. Although environmental justice is a relatively recent concept, it has become a focus of governmental environmental policy, UN actions, and the activities of many nongovernmental environmental organizations. Its development tracks our growing understanding of racism and wealth disparity in the United States and elsewhere, and of our understanding of inequality between the Global North and the Global South. In the era of climate change, climate justice is a particular focus.Environmental Justice: A Very Short Introduction defines the concept, identifies specific environmental justice populations, examines root causes, including racism, capitalism, and colonialism, and traces the history of the environmental justice movement and governmental responses to it. It concludes with suggestions for achieving this elusive goal.

  A certified psychedelic therapist explores the deeper healing offered by psychedelics to those working through trauma.   “Micah has created a must-read for anyone curious about the healing power of psychedelics. Healing Psychedelics demystifies the process and emphasizes safety and effectiveness, making it an essential guide for both new explorers and seasoned practitioners.” —Jessika Lagarde, psychedelic-assisted medicine facilitator, integration coach, and cofounder of Women On Psychedelics   Psychedelics are showing great promise as a new way to heal trauma and improve emotional wellness. Studies reveal that they can be effective in reducing PTSD, anxiety, and depression symptoms, even in cases that are resistant to other treatments. Stover offers a comprehensive and informative guide for both professionals and patients who are interested in learning more about psychedelic-assisted therapy.   Each chapter reveals a vignette taken directly from the psychedelic space that shows the medicines (medium and macro-doses of MDMA, psilocybin, ketamine, and cannabis), why they were chosen, and the process used for transformation during the sessions. Stover weaves in wisdom from indigenous and Mexican healers and practitioners with application exercises, writing prompts, and journal entries to deepen the reader’s healing journey. These exercises are applicable to all readers, whether you are working on your own or with a therapist.  Healing Psychedelics shows the complete process, enabling the reader to safely unlock the power of psychedelics to heal trauma and transform their life for a brighter future.

  Zero Trust Networks - Building...

  Perimeter defenses guarding your network aren't as secure as you might think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. This practical book introduces you to the zero trust model, a method that treats all hosts as if they're internet-facing, and considers the entire network to be compromised and hostile. 
   
   
   
  In this updated edition, the authors show you how zero trust lets you focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. You'll learn the architecture of a zero trust network, including how to build one using currently available technology. 
   
   
   
  You'll also explore fundamental concepts of a zero trust network, including trust engine, policy engine, and context aware agents; discover how this model embeds security within the system's operation, rather than layering it on top; use existing technology to establish trust among the actors in a network; migrate from a perimeter-based network to a zero trust network in production; examine case studies that provide insights into various organizations' zero trust journeys; and learn about the various zero trust architectures, standards, and frameworks.

  Learn the facts about sinus surgery and the medical and minimally invasive procedures available to you from a pioneer in otolaryngology. Sinuses. Everybody has them. Nobody likes them. The words “sinus” and “issues” are associated together so often, it’s no wonder that over half a million people receive sinus surgery in the US each year. But for many, the problems with their sinuses still persist well after receiving treatment.  With more than thirty years of experience as a sinus surgeon, Dr. Reuben Setliff wants patients to know as much as possible about their sinuses when facing the potentially life-altering choices of surgery and picking a long-term care routine. His tell-all book, Let’s Clear Things Up, explains the differences between optional and necessary surgery, the benefits of minimally invasive procedures, and natural ways to correct sinus problems all on our own. Get informed so that when you walk into a clinic, the air between you and your doctor is clear enough to get you breathing right the first time.
