A vibrant example of living literature, the Bhagavata Purana is a versatile Hindu sacred text written in Sanskrit verse. Finding its present form by the tenth century C.E., the work inspired several major north Indian devotional (bhakti) traditions as well as schools of dance and drama, and continues to permeate popular Hindu art and ritual in both India and the diaspora. Introducing the Bhagavata Purana's key themes while also examining its extensive influence on Hindu thought and practice, this collection conducts the first multidimensional reading of the entire text. Each essay focuses on a key theme of the Bhagavata Purana and its subsequent presence in Hindu theology, performing arts, ritual recitation, and commentary. The authors consider the relationship between the sacred text and the divine image, the text's metaphysical and cosmological underpinnings, its shaping of Indian culture, and its ongoing relevance to contemporary Indian concerns.

Formalized by the tenth century, the expansive Bhagavata Purana resists easy categorization. While the narrative holds together as a coherent literary work, its language and expression compete with the best of Sanskrit poetry. The text's theological message focuses on devotion to Krishna or Vishnu, and its philosophical outlook is grounded in the classical traditions of Vedanta and Samkhya. No other Purana has inspired so much commentary, imitation, and derivation. The work has grown in vibrancy through centuries of performance, interpretation, worship, and debate and has guided the actions and meditations of elite intellectuals and everyday worshippers alike. This annotated translation and detailed analysis shows how one text can have such enduring appeal. Key selections from the Bhagavata Purana are faithfully translated, while all remaining sections of the Purana are concisely summarized, providing the reader with a continuous and comprehensive narrative. Detailed endnotes explain unfamiliar concepts and several essays elucidate the rich philosophical and religious debates found in the Sanskrit commentaries.Together with the multidisciplinary readings contained in the companion volume The Bhagavata Purana: Sacred Text and Living Tradition (Columbia, 2013), this book makes a central Hindu masterpiece more accessible to English-speaking audiences and more meaningful to scholars of Hindu literature, philosophy, and religion.

Plants often encounter abiotic stresses including drought, salinity, flooding, high/low temperatures, and metal toxicity, among others. The majority of these stresses occur simultaneously and thus limit crop production. Therefore, the need of the hour is to improve the abiotic stresses tolerance of crop plants by integrating physiology, omics, and modern breeding approaches. This book covers various aspects including (1) abiotic stress responses in plants and progress made so far in the allied areas for trait improvements, (2) integrates knowledge gained from basic physiology to advanced omics tools to assist new breeding technologies, and (3) discusses key genes, proteins, and metabolites or pathways for developing new crop varieties with improved tolerance traits.

Basics of Sleep Technology: Fundamentals of Sleep Technology covers the critical elements of sleep and sleep technologies. The book gives a thorough understanding of sleep physiology, neurophysiological concepts, the principles of operation of the numerous equipment types used to diagnosis sleep disorders, and contemporary methodologies for diagnosing sleep disorders. As sleep professionals must understand the fundamentals of signal creation, acquisition principles, and data grading from a sleep diary, actigraphy, and polysomnography, this book provides all of this and more to anyone wishing to develop a comprehensive understanding of sleep.The book underscores that sleep medicine and technology are dynamic and rapidly growing medical specialties, and that one must stay up with the newest innovations in the area, but not at the price of the fundamentals. Users will find a solid background on cutting-edge advances in sleep medicine, diagnostics, monitoring, and therapeutics.Provides the latest, up-to-date knowledge regarding sleep medicine, including diagnosis and treatment, sleep technology, and monitoringPresents an authoritative reference resource for specialists and others facing unexpected challenges in the field of sleep medicineAppeals to readers from the most seasoned sleep researcher to those just beginning their advanced training

Laboratory Sleep Medicine: Fundamentals of Sleep Technology is the second of the Fundamentals of Sleep Technology books. It discusses balancing the fundamentals of sleep medicine with the newest innovations in the lab. High priority is given to practices that must be followed in sleep labs to guarantee the safety of patients and workers. To make information straightforward and easy to grasp, key events in each epoch of polysomnography are showcased. This serves to walk sleep professionals cogently through the history of sleep technology advancement. Laboratory Sleep Medicine: Fundamentals of Sleep Technology is keenly aware that manual titration with PAP is the gold standard treatment for sleep apnea. However, certain patients may require oxygen treatment, which is also covered in depth. In addition, case vignettes illustrate the development of a relevant report using the following: data from a sleep diary, actigraphy, and polysomnography. How to do sleep tests in unusual situations (such as at-home sleep apnea testing and testing in an intensive care unit) are also covered.Provides the latest, most up-to-date knowledge regarding sleep medicine: diagnosis and treatment, and sleep technology and monitoringOffers an authoritative reference resource for specialists in the medical and technical fields of sleep medicine regarding patient and healthcare worker safetyTraces the history of polysomnography from its earliest days to the present, offering readers a comprehensive timeline of their discipline

Clinical Sleep Medicine and Laboratory Management: Fundamentals of Sleep Technology has two primary aims. The first is to discuss sleep disorders, behavioural science topics as they apply to sleep technology, and other therapies for which a sleep technologist can collaborate with a sleep physician. The second is to explicate the business and managerial aspects of a sleep laboratory, with a view towards sleep technologists contributing to the continuation of patient services without profit concerns. These are two equally necessary areas of running a sleep laboratory, but too often one is overlooked in favor of the other. Specifically, Clinical Sleep Medicine and Laboratory Management: Fundamentals of Sleep Technology offers sleep laboratory managers information on indispensable topics such as minimum standards for a sleep laboratory, infection control practices in the sleep laboratory, electrical safety in the sleep laboratory, advocacy for the importance of sleep and sleep disorders, and financial management of the sleep laboratory. There has yet to be a book which fully encapsulates both the clinical aspects of a sleep laboratory, as well as the duty of keeping that laboratory fiscally sound and operational. This is that book.Discusses managerial and business aspects of the sleep laboratory so that sleep technologists can focus on providing services and optimal patient careOffers an authoritative treatment resource for specialists who work in the medical and technical fields of sleep medicineProvides the latest, up-to-date research regarding sleep medicine: diagnosis and treatment, and sleep technology and monitoring

Nitric Oxide in Plant Resilience to Abiotic Stress offers a detailed examination of this essential gasotransmitter’s pivotal role in bolstering plant defenses against environmental stressors. Part of the Plant Gasotransmitters and Molecules with Hormonal Activity series, the volume investigates the molecular mechanisms of nitric oxide (NO) biosynthesis and signaling, emphasizing how post-translational modifications like S-nitrosylation and tyrosine nitration govern key targets to activate adaptive stress responses. It systematically examines NO’s properties, detection techniques, and its regulation under both optimal and adverse conditions, providing a comprehensive understanding of how it modulates plant functions.Expanding beyond fundamental processes, the volume highlights NO’s crucial involvement across a spectrum of abiotic stresses-drought, salinity, temperature extremes, heavy metals, and UV radiation-unveiling its capacity to mitigate damage and strengthen plant resilience. It also discusses the crosstalk between NO and other signaling molecules, such as phytohormones and emerging growth regulators, revealing synergistic pathways that underpin sustainable agriculture.Designed for researchers, advanced students, and plant scientists worldwide, this work illuminates the potential of NO to drive innovations in breeding strategies, enabling crop improvement to overcome the challenges posed by a changing climate and expanding environmental pressures.Delivers a deep dive into the signaling pathways of NOShowcases compelling case studies and real-world applicationsExplores cutting-edge trends and future research directions

Written for sleep technologists, Clinical Atlas of Polysomnography provides basic information regarding normal sleep, sleep disorders, and electrophysiology that is outside of the scope of the AASM manual (AASM Manual for the Scoring of Sleep and Associated Events). It aims to act as a guide through the fundamental aspects of, for example, types of overnight sleep study, establishing a sleep laboratory, preparing the patient for a sleep evaluation study, placement of electrodes and leads, and the scientific aspects of such placement, i.e., why they are placed at that particular position. This information will be very useful in those parts of the globe where formal training in sleep technology is not yet available. Many further chapters focus on depicting real-time illustrations of sleep data as captured in the sleep laboratory and the scoring of recording data. Information regarding common montages, artifacts, and troubleshooting in the sleep laboratory will facilitate the reader’s journey as a trainee sleep technologist. While scoring sleep recordings, the "When you score the data" histogram can provide a great deal of useful information, and this has been explained in detail in this book. Most importantly, it is prudent to be able to write reports that are both informative and easy to understand by physicians who do not have advanced knowledge of sleep medicine. A chapter has been dedicated to explaining this in detail. Lastly, the authors have provided ready-made forms, questionnaires, and documents that can either be used as they are or with some modifications.This up-to-date and comprehensive volume will be an invaluable guide for technicians and physicians who wish to practice sleep medicine and will be useful for sleep technology and physician training programs. The volume is intended to complement, not be a substitute for, the AASM scoring manual, as many areas that are covered in the manual are not covered here.
