Sapiens: The Pillars of Civilization (Sapiens: A Graphic History #2)
by Yuval Noah HarariThe ebook is designed to be read on devices with large color displaysThe Kindle edition is incompatible with iOS. See below for a list of supported devices.This second volume of Sapiens: A Graphic History, the full-color graphic adaptation of Yuval Noah Harari’s #1 New York Times bestseller, focuses on the Agricultural Revolution—when humans fell into a trap we’ve yet to escape: working harder and harder with diminishing returns.What if humanity’s major woes—war, plague, famine and inequality—originated 12,000 years ago, when Homo sapiens converted from nomads to settlers, in pursuit of the fantasy of productivity and efficiency? What if by seeking to control plants and animals, humans ended up being controlled by kings, priests, and Kafkaesque bureaucracy? Volume 2 of Sapiens: A Graphic History–The Pillars of Civilization explores a crucial chapter in human development: the Agricultural Revolution. This is the story of how wheat took over the world; how an unlikely marriage between a god and a bureaucrat created the first empires; and how war, plague, famine, and inequality became an intractable feature of the human condition.But it’s not all doom and gloom with this book’s cast of entertaining characters and colorful humorous scenes. Yuval, Zoe, Prof. Saraswati, Cindy and Bill (now farmers), Detective Lopez, and Dr. Fiction, all introduced in Volume 1, once again travel the length and breadth of human history, this time investigating the impact the Agricultural Revolution has had on our species. The cunning Mephisto shows them how to ensnare humans, King Hammurabi lays down the law, and Confucius explains harmonious society. The origins of modern farming are introduced through Elizabethan tragedy; the changing fortunes of domesticated plants and animals are tracked in the columns of the Daily Business News; the story of urbanization is portrayed as a travel brochure, offering discount journeys to ancient Babylon and China; and the history of inequality unfolds in a superhero detective story; with guest appearances by historical and cultural personalities throughout such as Thomas Jefferson, Scarlett O'Hara, Margaret Thatcher, and John Lennon.Sapiens: A Graphic History, Volume 2 is a radical, witty and colorful retelling of the story of humankind for adults and young adults, and can be read on its own or in sequence with Volume I.
Sapientia Astrologica: I. Medieval Structures (1250-1500): Conceptual, Institutional, Socio-Political, Theologico-Religious and Cultural (Archimedes #55)
by H Darrel RutkinThis book explores the changing perspective of astrology from the Middle Ages to the Early Modern Era. It introduces a framework for understanding both its former centrality and its later removal from legitimate knowledge and practice. The discussion reconstructs the changing roles of astrology in Western science, theology, and culture from 1250 to 1500. The author considers both the how and the why. He analyzes and integrates a broad range of sources. This analysis shows that the history of astrology—in particular, the story of the protracted criticism and ultimate removal of astrology from the realm of legitimate knowledge and practice—is crucial for fully understanding the transition from premodern Aristotelian-Ptolemaic natural philosophy to modern Newtonian science. This removal, the author argues, was neither obvious nor unproblematic. Astrology was not some sort of magical nebulous hodge-podge of beliefs. Rather, astrology emerged in the 13th century as a richly mathematical system that served to integrate astronomy and natural philosophy, precisely the aim of the “New Science” of the 17th century. As such, it becomes a fundamentally important historical question to determine why this promising astrological synthesis was rejected in favor of a rather different mathematical natural philosophy—and one with a very different causal structure than Aristotle's.
Saproxylic Insects: Diversity, Ecology And Conservation (Zoological Monographs #1)
by Michael D. UlyshenThis volume offers extensive information on insect life in dying and dead wood. Written and reviewed by leading experts from around the world, the twenty-five chapters included here provide the most global coverage possible and specifically address less-studied taxa and topics. An overarching goal of this work is to unite literature that has become fragmented along taxonomic and geographic lines. A particular effort was made to recognize the dominant roles that social insects (e.g., termites, ants and passalid beetles) play in saproxylic assemblages in many parts of the world without overlooking the non-social members of these communities.The book is divided into four parts:· Part I “Diversity” includes chapters addressing the major orders of saproxylic insects (Coleoptera, Diptera, Hymenoptera, Hemiptera, Lepidoptera and Blattodea), broadly organized in decreasing order of estimated global saproxylic diversity. In addition to order-level treatments, some chapters in this part discuss groups of particular interest, including pollinators, hymenopteran parasitoids, ants, stag and passalid beetles, and wood-feeding termites.· Part II “Ecology” discusses insect-fungal and insect-insect interactions, nutritional ecology, dispersal, seasonality, and vertical stratification.· Part III “Conservation” focuses on the importance of primary forests for saproxylic insects, offers recommendations for conserving these organisms in managed forests, discusses the relationships between saproxylic insects and fire, and addresses the value of tree hollows and highly-decomposed wood for saproxylic insects. Utilization of non-native wood by saproxylic insects and the suitability of urban environments for these organisms are also covered.· Lastly, Part IV “Methodological Advancements” highlights molecular tools for assessing saproxylic diversity. The book offers an accessible and insightful resource for natural historians of all kinds and will especially appeal to entomologists, ecologists, conservationists and foresters.

Sarcopenia – Age-Related Muscle Wasting and Weakness
by Gordon S. LynchSome of the most serious consequences of aging are its effects on skeletal muscle. 'Sarcopenia', the progressive age-related loss of muscle mass and associated muscle weakness, renders frail elders susceptible to serious injury from sudden falls and fractures and at risk for losing their functional independence. Not surprisingly, sarcopenia is a significant public health problem throughout the developed world. There is an urgent need to better understand the neuromuscular mechanisms underlying age-related muscle wasting and to develop therapeutic strategies that can attenuate, prevent, or ultimately reverse sarcopenia. Significant research and development in academic and research institutions and in pharmaceutical companies is being directed to sarcopenia and to related health issues in order to develop and evaluate novel therapeutics. This book provides the latest information on sarcopenia from leading international researchers studying the cellular and molecular mechanisms underlying age-related changes in skeletal muscle and identifies strategies to combat sarcopenia and related muscle wasting conditions and neuromuscular disorders. The book provides a vital resource for researchers and practitioners alike, with information relevant to gerontologists, geriatricians, sports medicine physicians, physiologists, neuroscientists, cell biologists, endocrinologists, physical therapists, allied health and musculoskeletal practitioners, strength and conditioning specialists, athletic trainers, and students of the medical and biomedical sciences.
Sarcopenia: Molecular, Cellular, and Nutritional Aspects
by Dominique Meynial-DenisSarcopenia: Molecular, Cellular, and Nutritional Aspects describes the progressive loss of skeletal muscle mass and strength, defined by Rosenberg in 1997 as a hallmark of aging and referred to as &“sarcopenia.&” As life expectancy continues to increase worldwide, sarcopenia has become a major public health issue. The condition worsens in the presence of chronic diseases accelerating its progression. Sarcopenia is not considered to be &“a process of normative aging&” but according to the International Classification of Disease, Tenth Revision, Clinical Modification (ICD-10-CM), as a disease. As sarcopenia is an ineluctable process, prevention and management are the only options to promote healthy aging; these actions should perhaps be taken during youth. <p><p>Included in this book: <li>Features essential information on sarcopenia, its current definition, and molecular and cellular aspects of this disease <li>Discusses the development of physical frailty, a complication of sarcopenia, and predicts its occurrence in the older population <li>Presents alterations in muscle protein turnover and mitochondrial dysfunction in the aging process <li>Provides data on the negative involvement of sarcopenia in certain chronic diseases <li>Describes presbyphagia or age-related changes in the swallowing mechanism in older people <li>Details possible strategies to combat muscle wasting in healthy older adults and their limits <p><p>This book features information collected from pioneers or experts on human aging from around the globe, including Europe, Brazil, Canada, Japan and the United States. It is a valuable source of information for nutritional scientists, medical doctors, sports scientists, food scientists, dietitians, students in these fields, and for anyone interested in nutrition. We hope this book provides a better understanding of sarcopenia which inevitably occurs with aging without weight loss. Moreover, this book will supply information outlining strategies to prevent or limit muscle wasting due to normal aging in order to promote successful aging.
Sarcopenia: Research and Clinical Implications (Practical Issues in Geriatrics)
by Nicola Veronese Charlotte Beaudart Shaun SabicoThis book offers a concise and updated guide for all readers (physicians and non-physicians) interested in gaining a comprehensive and precise understanding of sarcopenia. Over the last several years, sarcopenia has increasingly developed from being a concept known only in research settings to one that is commonly explored in journals and scientific meetings for various disciplines, such as geriatrics, rheumatology and rehabilitation medicine. Thus, all domains of sarcopenia, from molecular aspects to clinical management, represent highly active areas of research and clinical practice for health professionals in a variety of fields, including geriatric medicine, nutrition, and epidemiology. Despite being a relatively new concept in medicine, sarcopenia is increasingly being recognized as an important determinant of other health conditions, including mortality and disability. This book, written by experts from around the globe, covers several core aspects of sarcopenia management, from molecular mechanisms to genetics, epidemiology, diagnosis and finally treatment, including the clinical impact of sarcopenia as a risk factor, the known genetic and molecular aspects that can aid in predicting sarcopenia, and selected treatment and therapy concepts, including indications for nutrition and physical exercise. Sharing data from the latest studies, it will be of considerable interest not only for geriatricians, but also for a wide range of other readers.

Satellite Boy: The International Manhunt for a Master Thief That Launched the Modern Communication Age
by ANDREW AMELINCKXSpanning the underworld haunts of Montreal to Havana and Miami in the early days of the Cold War, Satellite Boy reveals the unlikely connection between an audacious bank heist and the &“other Space Race&” that gave birth to the modern communication ageOn April 6, 1965, Georges Lemay was relaxing on his yacht in a south Florida marina following one of the largest and most daring bank heists in Canadian history. For four years, the roguishly handsome criminal mastermind hid in plain sight, eluding capture and the combined efforts of the FBI, Interpol, and the Royal Canadian Mounted Police. His future appeared secure.What Lemay didn&’t know was that less than two hundred miles away at Cape Canaveral, a brilliant engineer named Harold Rosen was about to usher in the age of global live television with the launch of the world&’s first twenty-four-hour commercial communications satellite. Rosen&’s extraordinary accomplishment would not only derail Lemay&’s cushy life but change the world forever.Brimming with criminal panache and technological intrigue, and set against a turbulent and iconic period that includes the moon landing and the civil rights movement, Satellite Boy tells the largely forgotten, high-stakes story of the two equally driven men who inadvertently launched the modern era.

Satellite Communications Payload and System
by Teresa M. BraunThis is the first book primarily about the satellite payload of satellite communications systems. It represents a unique combination of practical systems engineering and communications theory. It tells about the satellites in geostationary and low-earth orbits today, both the so-called bent-pipe payloads and the processing payloads. The on-orbit environment, mitigated by the spacecraft bus, is described. The payload units (e.g. antennas and amplifiers), as well as payload-integration elements (e.g. waveguide and switches) are discussed in regard to how they work, what they do to the signal, their technology, environment sensitivity, and specifications. At a higher level are discussions on the payload as an entity: architecture including redundancy; specifications--what they mean, how they relate to unit specifications, and how to verify; and specification-compliance analysis ("budgets") with uncertainty. Aspects of probability theory handy for calculating and using uncertainty and variation are presented. The highest-level discussions, on the end-to-end communications system, start with a practical introduction to physical-layer communications theory. Atmospheric effects and interference on the communications link are described. A chapter gives an example of optimizing a multibeam payload via probabilistic analysis. Finally, practical tips on system simulation and emulation are provided. The carrier frequencies treated are 1 GHz and above. Familiarity with Fourier analysis will enhance understanding of some topics. References are provided throughout the book for readers who want to dig deeper.Payload systems engineers, payload proposal writers, satellite-communications systems designers and analysts, and satellite customers will find that the book cuts their learning time. Spacecraft-bus systems engineers, payload unit engineers, and spacecraft operators will gain insight into the overall system. Students in systems engineering, microwave engineering, communications theory, probability theory, and communications simulation and modelling will find examples to supplement theoretical texts.

Satellite Equivalence Orbits: Analysis of Orbits Combining Different Motions (Space Technology Library #42)
by Ernst Friedrich JochimThis book presents the essential characteristics of the different satellite motions. Satellite motions can be classified as anomalistic, draconitic, tropical, Hansen-, Kepler-, meridional, Sun-synodical, Moon-synodical motion, depending on the relevant reference point. When two of these types of motions (in some cases even more than two) are coupled, satellite orbits are obtained, which are called equivalence orbits in this book. They share the special properties of the different coupled motions and are therefore of particular interest in the selection of special satellite orbits. In the book the author calculates mean equivalence orbits with secular perturbation formulas, as well as true equivalence orbits considering a complete orbit model including periodic motion effects. Some of the equivalence orbits can be determined unambiguously and with extremely high accuracy, they are stable in the long term. Others can only be found with low accuracy and reduced stability. The author investigates all possible combinations and the associated general equations of condition are derived in each case. Some well-known families of satellite orbits, such as the Sun-synchronous orbits, can be interpreted as mean equivalence orbits. The study of their stability is of great interest in orbit mechanics. Special applications and numerous numerical examples, graphical representations of all possible ranges of the Kepler elements, and detailed studies of the stability of particularly important equivalence orbits are carried out using the Brouwer orbit model as well as the modification by Eckstein. This lays the foundation for possible refinements using arbitrary extended orbital models and for possibly required orbital corrections. Numerous problems are to deepen the treated topics and/or to stimulate for further investigations. The book will be of interest to Astrodynamics and Aerospace Engineers as well as graduate students studying satellite orbits.
Satellite Gravity and the Geosphere: Contributions to the Study of the Solid Earth and Its Fluid Envelope
by Committee on Earth Gravity from SpaceFor the past three decades, it has been possible to measure the earth's static gravity from satellites. Such measurements have been used to address many important scientific problems, including the earth's internal structure, and geologically slow processes like mantle convection. In principle, it is possible to resolve the time-varying component of the gravity field by improving the accuracy of satellite gravity measurements. These temporal variations are caused by dynamic processes that change the mass distribution in the earth, oceans, and atmosphere. Acquisition of improved time-varying gravity data would open a new class of important scientific problems to analysis, including crustal motions associated with earthquakes and changes in groundwater levels, ice dynamics, sea-level changes, and atmospheric and oceanic circulation patterns. This book evaluates the potential for using satellite technologies to measure the time-varying component of the gravity field and assess the utility of these data for addressing problems of interest to the earth sciences, natural hazards, and resource communities.
Satellite Measurements of Clouds and Precipitation: Theoretical Basis (Springer Remote Sensing/Photogrammetry)
by Hirohiko MasunagaThis book provides a thorough introductory description of the physical principles underlying the satellite remote sensing of clouds and precipitation. A diverse collection of satellite sensors is covered, including imagers, radars, and sounders over a broad spectral range from visible to microwave radiation. The progress in satellite instrument technology during the past two decades as represented by the Tropical Rainfall Measuring Mission (TRMM), CloudSat, and Global Measurement Mission (GPM) satellites has drastically improved our capability of measuring clouds and precipitation across the globe. At the same time, such rapid progress makes it increasingly challenging for scientists without specialized skills in remote sensing to fully grasp how satellite measurements are being made. This book is designed to mitigate that challenge. The targeted readers are graduate students and professional scientists seeking an extended summary of the theoretical background behind observations from space, ranging from fundamental physics (the statistical mechanics and radiative processes, for instance) to more practical levels of theory such as retrieval algorithm design.
