Zenn Scarlett
by Christian SchoonZenn Scarlett is a bright, determined, occasionally a-little-too-smart-for-her-own-good 17-year-old girl training hard to become an exoveterinarian. That means she's specializing in the treatment of exotic alien life forms, mostly large and generally dangerous. Her novice year of training at the Ciscan Cloister Exovet Clinic on Mars will find her working with alien patients from whalehounds the size of a hay barn to a baby Kiran Sunkiller, a colossal floating creature that will grow up to carry a whole sky-city on its back.But after a series of inexplicable animal escapes from the school and other near-disasters, the Cloister is in real danger of being shut down by a group of alien-hating officials. If that happens, Zenn knows only too well the grim fate awaiting the creatures she loves.Now, she must unravel the baffling events plaguing her school, before someone is hurt or killed, before everything she cares about is ripped away from her and her family forever. To solve this mystery - and live to tell about it - Zenn will have to put her new exovet skills to work in ways she never imagined, and in the process learn just how powerful compassion and empathy can be.

Zeptosecond Dynamics of Transfer‐Triggered Breakup: Mechanisms, Timescales, And Consequences For Fusion (Springer Theses)
by Kaitlin Jennifer CookCombining incisive experiments with the latest theoretical advances, this book presents an extensive study of transfer-triggered breakup, the dominant process by which breakup occurs in reactions involving light, weakly bound nuclei. It demonstrates not only that lifetimes of resonant states shorter than a zeptosecond are crucially important for these reactions to suppress complete fusion, but also that such short lifetimes are experimentally accessible. By making quantitative predictions of the effect of breakup from short-lived resonant states on incomplete fusion at above-barrier energies, the book suggests that the extent to which near-target breakup can suppress complete fusion is much more limited than previously thought. With an impressive amount of complex data and state-of-the-art models, which were developed, modified, and tested over course of the Ph.D., it examines all aspects of nuclear reactions – nuclear models, modern detectors and spectrometers, as well as data analysis, and offers a detailed discussion of experimental results and technical developments like new radioactive beams. This excellent and beautifully written book presents outstanding quality experimental work that establishes a cornerstone in our understanding of the reaction dynamics of light weakly bound nuclei at energies around the Coulomb barrier.

Zero Decibels
by George M FoyHave our noise-soaked lives driven us mad? And is absolute silence an impossible goal--or the one thing that can save us? A lively tale of one man's quest to find the grail of total quiet.---" I don't know at what point noise became intolerable for me," George Michelsen Foy writes as he recalls standing on a subway platform in Manhattan, hands clamped firmly over his ears, face contorted in pain. But only then does Foy realize how overwhelmed he is by the city's noise and vow to seek out absolute silence, if such an absence of sound can be discovered.Foy begins his quest by carrying a pocket-sized decibel meter to measure sound levels in the areas he frequents most--the subway, the local café, different rooms of his apartment--as well as the places he visits that inform his search, including the Parisian catacombs, Joseph Pulitzer's "silent vault," the snowy expanses of the Berkshires, and a giant nickel mine in Canada, where he travels more than a mile underground to escape all human-made sound. Along the way, Foy experiments with noise-canceling headphones, floatation tanks, and silent meditation before he finally tackles a Minnesota laboratory's anechoic chamber that the Guinness Book of World Records calls "the quietest place on earth," and where no one has ever endured even forty-five minutes alone in its pitch-black interior before finding the silence intolerable.Drawing on history, science, journalistic reportage, philosophy, religion, and personal memory, as well as conversations with experts in various fields whom he meets during his odyssey, Foy finds answers to his questions: How does one define silence? Did human beings ever experience silence in their early history? What is the relationship between noise and space? What are the implications of silence and our need for it--physically, mentally, emotionally, politically? Does absolute silenceactually exist? If so, do we really want to hear it? And if we do hear it, what does it mean to us?According to the Environmental Protection Agency, 30 million Americans suffer from environment-related deafness in today's digital age of pervasive sound and sensory overload. Roughly the same number suffer from tinnitus, a condition, also environmentally related, that makes silence impossible in even the quietest places. In this respect, Foy's quest for silence represents more than a simple psychological inquiry; both his queries and his findings help to answer the question "How can we live saner, healthier lives today?"Innovative, perceptive, and delightfully written, Zero Decibels will surely change how we perceive and appreciate the soundscape of our lives.

Zero Kelvin
by Richard NormanPresent-day astronomy, vast, complex, is looking through darkness to distant objects and times. Yet its discoveries aren't exclusively scientific: from the moons of Pluto to the Doppler effect, the night sky screens a place where math meets myth. Now, in Zero Kelvin, in scenes that shift from the mountains of Goma to the mountains of the moon, from galaxies that feast upon their neighbours to a solar sail unfurling above Earth's orbit, Richard Norman's poetry probes both newly glimpsed corners of the universe, and the myths which bring them into focus. Experiment. It is a human urge-to orbit backwards at great speed.Experimentally, you do itand then the crack of lightning, the open-ended snowflake, splits the sky. Just as the sculptor cut the fat off space,you going backwards renders time. Seconds drop like filings when a magnet is turned off.

Zero – Much to Do About Nothing?
by Jim E. RiviereZero – Much to Do About Nothing? is a thought-provoking work that delves into the complexities of defining “zero” in various fields, from mathematics and physics to pharmacology and food safety. Drawing on his extensive experience in teaching, research and managing a USDA-supported chemical food safety program, Jim E. Riviere provides readers with practical examples and case studies that highlight the challenges of defining “zero” in different contexts across a wide range of fields. In his four decades of university teaching, doing research in pharmacology, toxicology, biomathematics and nanoscience, Dr. Riviere has repeatedly encountered the concept of “zero” and the broad parameters utilized to achieve a proper definition. "Zero” enters when discussions concern defining "nothing", "negligible", "very small", "below level of detection", "absence of effect" or "safe". This renders the term “zero” incredibly confusing to scientists, practitioners and regulators. This book explores the origin of the concept of “zero” in mathematics, physics, chemistry and statistics and how these concepts migrated to fields such as pharmacology, toxicology, cancer research and food safety, as well as to the legal profession in the form of regulatory science and policy. Specific chapters deal with the application of “zero” to these distinct fields. The main focus throughout the book is to illustrate how important context is to the definition of “zero”. This has assumed greater relevance today with the advent of nanoscience where “small” implies different physical and chemical behavior and the use of artificial Intelligence to analyze vast troves of data from the web. The goal of the book is to provide much-needed clarity about "zero" and break down the many issues preventing it. Riviere expertly explains how the concept of “zero” is essential to a wide range of issues, from defining negligible amounts of a substance to determining the safety of a product or process. He shows how the term “zero” can have different meanings in different fields and how this can lead to confusion and misunderstandings among scientists, practitioners and regulators. Whether you're working in Food Safety, Chemistry, Pharmacology, Mathematics, Physics or beyond, Zero – Much to Do About Nothing? is a relatable book that will deepen your understanding of the concept of “zero” and its diverse applications.
