Kentucky's Natural Heritage: An Illustrated Guide to Biodiversity
by Deborah White Greg Abernathy Ellis L. Laudermilk Marc Evans“[A] beautiful book about a state that has just about everything except a beach: mountains, swamps, rivers, plains, and, of course, the lovely bluegrass.” —Baton Rouge AdvocateKentucky’s abundance of plant and animal life, from the bottomland swamps in the west to the rich Appalachian forests in the east, is extraordinary as well as beautiful. Glades, prairies, forests, wetlands, rivers, and caves form a biologically diverse patchwork that is unique to the state. Kentucky’s Natural Heritage: An Illustrated Guide to Biodiversity provides an essential reference to the remarkable natural history of the commonwealth and is a rallying call for the conservation of this priceless legacy.Kentucky’s ecosystems teem with diverse native species, some of which are found nowhere else in the world. Kentucky’s Natural Heritage brings these sometimes elusive creatures into close view, from black-throated green warblers to lizard skin liverworts. The aquatic systems of the state are home to rainbow darters, ghost crayfish, salamander mussels, and an impressive array of other species that constitute some of the greatest levels of freshwater diversity on the planet.Richly detailed and lavishly illustrated with more than 250 color photos, maps, and charts, Kentucky’s Natural Heritage is the definitive compendium of the commonwealth’s amazing diversity and presents a persuasive argument for the necessity of conservation. Organized by a team from the Kentucky State Nature Preserves Commission, the book is an outgrowth of the agency’s focus on biodiversity protection.“Between its covers, readers will find details of Kentucky’s vanished natural areas and catalogue of the increasingly rare animal, plants and unique habitats that urgently need protection.” —Louisville Courier Journal

Kepler (Dover Books On Astronomy Ser.)
by Max CasparA towering figure in intellectual history and one of the fathers of modern astronomy, the great mathematician Johannes Kepler (1571–1630) is best known for his discovery of the three laws of planetary motion, which paved the way for a dynamic explanation of the heavenly phenomena. At a time when the Ptolemaic view still prevailed in official circles, Kepler undertook to prove the truth of the Copernican world view and through exceptional perseverance and force of intellect achieved that goal. His epochal intellectual feats are completely and thoroughly described in this splendid work, considered the definitive biography of Kepler. Drawing on a wealth of primary sources, the author presents a fascinating and erudite picture of Kepler's scientific accomplishments, his public life (work with Tycho Brahe, the Danish astronomer; mathematical appointments at Graz, Prague, and Linz; pioneering work with calculus and optics, and more) and his personal life: childhood and youth, financial situation, his mother's trial as a witch, his own lifelong fear of religious persecution, his difficulties in choosing one of eleven possible young women as his second wife, and more, through his last years in Ulm and death in Regensburg.Until his death in 1956, Professor Max Caspar was the world's foremost Kepler scholar. He had spent over two-thirds of his life assembling, cataloging, describing, analyzing, and editing Kepler's works. To this biography he brought tremendous learning and passionate enthusiasm for his subject, creating an unsurpassed resource on the life and work of one of history's greatest scientific minds. Originally published in German and superbly translated into English by C. Doris Hellman, Kepler will fascinate scholars and general readers alike.
Kepler Problem in the Presence of Dark Energy, and the Cosmic Local Flow (SpringerBriefs in Physics)
by Arthur Chernin Alexander SilbergleitThis book derives and analyzes all solutions to the Kepler problem with dark energy (DE), presenting significant results such as: (a) all radial infinite motions obey Hubble’s law at large times; (b) all orbital infinite motions are asymptotically radial and obey Hubble’s law; (c) infinite orbital motions strongly dominate the finite ones. This clearly shows the effect of repulsive DE: In the classical Kepler problem, all orbital motions are finite for negative energies and infinite in the opposite case. Another DE effect is spatial localization of bounded orbits: mostly, they are within the equilibrium sphere, where the attractive Newtonian force outbalances the repulsive force of DE. This problem is of particular current interest due to recent studies of the local flows of galaxies showing domination of DE in their dynamics; the book discusses this observation in detail.
Kepler and the Universe
by David K. LoveA contemporary of Galileo and a forerunner of Isaac Newton, Johannes Kepler (1571-1630) was a pioneering German scientist and a pivotal figure in the history of astronomy. This colorful, well-researched biography brings the man and his scientific discoveries to life, showing how his contributions were every bit as important as those of Copernicus, Galileo, and Newton. It was Kepler who first advocated the completely new concept of a physical force emanating from the sun that controls the motion of the planets--today we call this gravity and take it for granted. He also established that the orbits of the planets were elliptical in shape and not circular. And his three laws of planetary motion are still used by contemporary astronomers and space scientists. The author focuses not just on these and other momentous breakthroughs but also on Kepler's arduous life, punctuated by frequent tragedy and hardships. His first wife died young, and eight of the twelve children he fathered succumbed to disease in infancy or childhood. He was frequently caught up in the religious persecutions of the day. His mother narrowly escaped death when she was accused of being a witch.Intermingling historical and personal details of Kepler's life with lucid explanations of his scientific research, this book presents a sympathetic portrait of the man and underscores the critical importance of Kepler's discoveries in the history of astronomy.From the Hardcover edition.

Kepler's Philosophy and the New Astronomy
by Rhonda MartensJohannes Kepler contributed importantly to every field he addressed. He changed the face of astronomy by abandoning principles that had been in place for two millennia, made important discoveries in optics and mathematics, and was an uncommonly good philosopher. Generally, however, Kepler's philosophical ideas have been dismissed as irrelevant and even detrimental to his legacy of scientific accomplishment. Here, Rhonda Martens offers the first extended study of Kepler's philosophical views and shows how those views helped him construct and justify the new astronomy. Martens notes that since Kepler became a Copernican before any empirical evidence supported Copernicus over the entrenched Ptolemaic system, his initial reasons for preferring Copernicanism were not telescope observations but rather methodological and metaphysical commitments. Further, she shows that Kepler's metaphysics supported the strikingly modern view of astronomical method that led him to discover the three laws of planetary motion and to wed physics and astronomy--a key development in the scientific revolution. By tracing the evolution of Kepler's thought in his astronomical, metaphysical, and epistemological works, Martens explores the complex interplay between changes in his philosophical views and the status of his astronomical discoveries. She shows how Kepler's philosophy paved the way for the discovery of elliptical orbits and provided a defense of physical astronomy's methodological soundness. In doing so, Martens demonstrates how an empirical discipline was inspired and profoundly shaped by philosophical assumptions.
Kepler's Witch: An Astronomer's Discovery of Cosmic Order Amid Religious War, Political Intrigue, and the Heresy Trial of His Mother
by James A. ConnorSet against the backdrop of the witchcraft trial of his mother, this lively biography of Johannes Kepler – 'the Protestant Galileo' and 16th century mathematician and astronomer – reveals the surprisingly spiritual nature of the quest of early modern science. In the style of Dava Sobel's Galileo's Daughter, Connor's book brings to life the tidal forces of Reformation, Counter–Reformation, and social upheaval. Johannes Kepler, who discovered the three basic laws of planetary motion, was persecuted for his support of the Copernican system. After a neighbour accused his mother of witchcraft, Kepler quit his post as the Imperial mathematician to defend her. James Connor tells Kepler's story as a pilgrimage, a spiritual journey into the modern world through war and disease and terrible injustice, a journey reflected in the evolution of Kepler's geometrical model of the cosmos into a musical model, harmony into greater harmony. The leitmotif of the witch trial adds a third dimension to Kepler's biography by setting his personal life within his own times. The acts of this trial, including Kepler's letters and the accounts of the witnesses, although published in their original German dialects, had never before been translated into English. Echoing some of Dava Sobel's work for Galileo's Daughter, Connor has translated the witch trial documents into English. With a great respect for the history of these times and the life of this man, Connor's accessible story illuminates the life of Kepler, the man of science, but also Kepler, a man of uncommon faith and vision.

Keratin as a Protein Biopolymer: Extraction from Waste Biomass and Applications (Springer Series on Polymer and Composite Materials)
by Ashok Kumar Swati SharmaThis book provides information about the sources, structure, and properties of keratin as well as its applications. The extraction from different biomass sources (e.g. feathers, hairs, nails, horn, hoof, and claws) as well as the characterization methods of these extracted materials are explained. The development of bioproducts from keratins is challenging and limited since they are neither soluble in polar solvents nor in non-polar solvents. Therefore, the utilization of different microorganisms for the degradation of keratin is also discussed.The main aim of this book is to highlight the unique features of keratin and to update readers with the possible prospects to develop various value-added products from keratins. The book is highly interesting to researchers working in industry and academia on bioproducts, tissue engineering, biocomposites, biofilm, and biofibers.

Kernel Ridge Regression in Clinical Research
by Aeilko H. Zwinderman Ton J. CleophasIBM (international business machines) has published in its SPSS statistical software 2022 update a very important novel regression method entitled Kernel Ridge Regression (KRR). It is an extension of the currently available regression methods, and is suitable for pattern recognition in high dimensional data, particularly, when alternative methods fail. Its theoretical advantages are plenty and include thekernel trick for reduced arithmetic complexity,estimation of uncertainty by Gaussians unlike histograms,corrected data-overfit by ridge regularization,availability of 8 alternative kernel density models for datafit.A very exciting and wide array of preliminary KRR research has already been published by major disciplines (like studies in quantum mechanics and nuclear physics, studies of molecular affinity / dynamics, atomisation energy studies, but also forecasting economics studies, IoT (internet of things) studies for e-networks, plant stress response studies, big data streaming studies, etc). In contrast, it is virtually unused in clinical research. This edition is the first textbook and tutorial of kernel ridge regressions for medical and healthcare students as well as recollection / update bench, and help desk for professionals. Each chapter can be studied as a standalone, and, using, real as well as hypothesized data, it tests the performance of the novel methodology against traditional regression analyses. Step by step analyses of over 20 data files stored at Supplementary Files at Springer Interlink are included for self-assessment. We should add that the authors are well qualified in their field. Professor Zwinderman is past-president of the International Society of Biostatistics (2012-2015) and Professor Cleophas is past-president of the American College of Angiology (2000-2002). From their expertise they should be able to make adequate selections of modern KRR methods for the benefit of physicians, students, and investigators. The authors have been working and publishing together for 24 years and their research can be characterized as a continued effort to demonstrate that clinical data analysis is not mathematics but rather a discipline at the interface of biology and mathematics.

Kernenergie: Kraftwerkstypen, Entwicklungen und Risiken
by Hartmut FreyDie Nachfrage nach fossilen Brennstoffen steigt stetig an. Zugleich produzieren sie in der Stromgestehung aufgrund der Oxidationsprozesse Kohlendioxid, das dann in die Atmosphäre entweicht und dort als Treibhausgas die Wärmestrahlung adsorbiert und remittiert. Seit geraumer Zeit werden in einigen Ländern neue Kernkraftwerke gebaut. Die weltweite Akzeptanz der Stromerzeugung durch Kernenergie hat durch die Katastrophen von Tschernobyl und Fukushima gelitten, wobei Tschernobyl auf menschliches Versagen beruhte, während die Reaktorblöcke in Fukushima optimal auf Erdbeben ausgelegt waren, nicht aber auf den eines Tsunami. Das Buch fasst den Stand der Technik zusammen, berücksichtigt Beteiligungsprozesse der Öffentlichkeit sowie absehbare Entwicklungen in den Lebensgewohnheiten und politische Vorgaben.

Ketamine: From Abused Drug to Rapid-Acting Antidepressant
by Kenji Hashimoto Soichiro Ide Kazutaka IkedaThis book presents the latest data from basic research and clinical trials supporting the effectiveness of ketamine as a treatment for depression, bipolar disorder, and suicidal behavior, setting these positive findings within the context of the serious problem of ketamine abuse. The first part of the book focuses on the evidence regarding ketamine abuse, with specific reference to Asian countries, and discusses countermeasures and complication management. It then addresses the mechanisms underlying the antidepressant and side effects of ketamine, which have remained elusive, describing and discussing important new research findings. Further, it explains insights gained from whole brain imaging in rodents and from behavioral pharmacology, and presents evidence regarding the role of gut microbiota, the NMDA receptor GluN2D subunit, and the lateral habenula in the actions of ketamine. These advances form the basis for the safer use of ketamine in patients with treatment-resistant depression and are expected to lead to the development of new antidepressants.
