Sedimentation Velocity Analytical Ultracentrifugation: Discrete Species and Size-Distributions of Macromolecules and Particles
by Peter SchuckA follow-up to the experimental and instrumental aspects described in Basic Principles of Analytical Ultracentrifugation, the volume Sedimentation Velocity Analytical Ultracentrifugation: Discrete Species and Size-Distributions of Macromolecules and Particles describes the theory and practice of data analysis. Mathematical models for the sedimentation process and the evolution of detected signals are developed in a comprehensive framework, jointly with the description of current and historical strategies for how to extract from noisy experimental data the physical parameters of interest, such as size, mass, and shape, composition, and polydispersity of sedimenting particles. The methods are extensively illustrated, and supported with practical applications, as well as cross-references where to find the methods in the public domain software SEDFIT and SEDPHAT. The systems covered are discrete or polydisperse mixtures of sedimenting molecules or particles in dilute solution, such as proteins and other biomolecules and their stable complexes, man-made polymers, and nanoparticles, observed in different optical systems. A useful reference for researchers and graduate students of macromolecular disciplines, these methods form the essential foundation for the analysis of dynamic interacting systems, which are covered in the volume Sedimentation Velocity Analytical Ultracentrifugation: Interacting Systems.

Sediments in the Tema Harbour: Chemical Pollution and Sedimentation Rates (IHE Delft PhD Thesis Series)
by Benjamin O. BotweSediment pollution and accumulation in harbours are major environmental issues and studies that advance their solutions are essential for harbour sustainability. This book provides the first comprehensive assessment of chemical pollution in sediments and sediment accumulation rates in the tropical Tema Harbour (Ghana). This book contributes to improving our ability to use an integrated approach involving sediment chemistry and bioassays in one comprehensive assessment of the contamination state of a tropical coastal environment. Whole-sediment toxicity bioassays using the amphipod Corophium volutator and the polychaete Hediste diversicolor as bioindicators were combined with data on concentrations of total metal and metal binding forms, radionuclides, organochlorine pesticides and polycyclic aromatic hydrocarbons in bottom sediments as well as total metal concentrations in settling silt-clay particles collected by sediment traps to characterise the hazard, risk and impact of sediments from the tropical coastal Tema Harbour.
The Sediments of Time: My Lifelong Search for the Past
by Meave Leakey Samira Leakey"Extraordinary . . . This inspirational autobiography stands among the finest scientist memoirs." —New York Times Book Review, Editors' ChoiceMeave Leakey&’s thrilling, high-stakes memoir—written with her daughter Samira—encapsulates her distinguished life and career on the front lines of the hunt for our human origins, a quest made all the more notable by her stature as a woman in a highly competitive, male-dominated field. In The Sediments of Time, preeminent paleoanthropologist Meave Leakey brings us along on her remarkable journey to reveal the diversity of our early pre-human ancestors and how past climate change drove their evolution. She offers a fresh account of our past, as recent breakthroughs have allowed new analysis of her team&’s fossil findings and vastly expanded our understanding of our ancestors. Meave&’s own personal story is replete with drama, from thrilling discoveries on the shores of Lake Turkana to run-ins with armed herders and every manner of wildlife, to raising her children and supporting her renowned paleoanthropologist husband Richard Leakey&’s ambitions amidst social and political strife in Kenya. When Richard needs a kidney, Meave provides him with hers, and when he asks her to assume the reins of their field expeditions after he loses both legs in a plane crash, the result of likely sabotage, Meave steps in. The Sediments of Time is the summation of a lifetime of Meave Leakey&’s efforts; it is a compelling picture of our human origins and climate change, as well as a high-stakes story of ambition, struggle, and hope."A fascinating glimpse into our origins. Meave Leakey is a great storyteller, and she presents new information about the far off time when we emerged from our ape-like ancestors to start the long journey that has led to our becoming the dominant species on Earth. That story, woven into her own journey of research and discovery, gives us a book that is informative and captivating, one that you will not forget."—Jane Goodall, PhD, DBE, Founder of the Jane Goodall Institute

The Seductions of Darwin: Art, Evolution, Neuroscience
by Matthew RampleyThe surge of evolutionary and neurological analyses of art and its effects raises questions of how art, culture, and the biological sciences influence one another, and what we gain in applying scientific methods to the interpretation of artwork. In this insightful book, Matthew Rampley addresses these questions by exploring key areas where Darwinism, neuroscience, and art history intersect.Taking a scientific approach to understanding art has led to novel and provocative ideas about its origins, the basis of aesthetic experience, and the nature of research into art and the humanities. Rampley’s inquiry examines models of artistic development, the theories and development of aesthetic response, and ideas about brain processes underlying creative work. He considers the validity of the arguments put forward by advocates of evolutionary and neuroscientific analysis, as well as its value as a way of understanding art and culture. With the goal of bridging the divide between science and culture, Rampley advocates for wider recognition of the human motivations that drive inquiry of all types, and he argues that our engagement with art can never be encapsulated in a single notion of scientific knowledge.Engaging and compelling, The Seductions of Darwin is a rewarding look at the identity and development of art history and its complicated ties to the world of scientific thought.

See Right Through Me
by Savvas AndronikouThis atlas demonstrates all components of the body through imaging, in much the same way that a geographical atlas demonstrates components of the world. Each body system and organ is imaged in every plane using all relevant modalities, allowing the reader to gain knowledge of density and signal intensity. Areas and methods not usually featured in imaging atlases are addressed, including the cranial nerve pathways, white matter tractography, and pediatric imaging. As the emphasis is very much on high-quality images with detailed labeling, there is no significant written component; however, 'pearl boxes' are scattered throughout the book to provide the reader with greater insight. This atlas will be an invaluable aid to students and clinicians with a radiological image in hand, as it will enable them to look up an exact replica and identify the anatomical components. The message to the reader is: Choose an organ, read the 'map,' and enjoy the journey!
Seed Activism: Patent Politics and Litigation in the Global South (Food, Health, and the Environment)
by Karine E. PeschardHow lawsuits around intellectual property in Brazil and India are impacting the patentability of plants and seeds, farmers&’ rights, and the public interest.Over the past decade, legal challenges have arisen in the Global South over patents on genetically modified crops. In this ethnographic study, Karine E. Peschard explores the effects of these disputes on people&’s lives, while uncovering the role of power—material, institutional, and discursive—in shaping laws and legal systems. The expansion of corporate intellectual property (IP), she shows, negatively impacts farmers&’ rights and, by extension, the right to food, since small farms produce the bulk of food for domestic consumption. Peschard sees emerging a new legal common sense concerning the patentability of plant-related inventions, as well as a balance among IP, farmers&’ rights, and the public interest.Peschard examines the strengthening of IP regimes for plant varieties, the consolidation of the global biotech industry, the erosion of agrobiodiversity, and farmers&’ dispossession. She shows how litigants question the legality of patents and private IP systems implemented by Monsanto for royalties on three genetically modified crop varieties, Roundup Ready soybean in Brazil and Bt cotton and Bt eggplant in India. Peschard argues that these private IP systems have rendered moot domestic legislation on plant variety protection and farmers&’ rights. This unprecedented level of corporate concentration in such a vital sector raises concerns over the erosion of agricultural biodiversity, farmers&’ rights and livelihoods, food security, and, ultimately, the merits of extending IP rights to higher life forms such as plants.
Seed Biology and Yield of Grain Crops
by Dennis EgliThis new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are partly regulated within the seed itself. Providing a timely update in this field and highlighting the impact of the seed on grain crop yields, this book: · Describes all aspects of seed growth and development, including environmental and genetic effects on growth rate and length of the filling period. · Discusses the role of the seed in determining the two main yield components: individual seed weight and number of seeds per unit area. · Uses the concepts and models that have been developed to understand crop management and yield improvement. Substantially updated with new research and further developments of the practical applications of the concepts explored, this book is essential reading for those concerned with seed science and crop yield, including agronomists, crop physiologists, plant breeders, and extension workers. It is also a valuable source of information for lecturers and graduate students of agronomy and plant physiology.
Seed-Borne Diseases of Agricultural Crops: Detection, Diagnosis & Management
by Ravindra Kumar Anuja GuptaThe global population is increasing rapidly, and feeding the ever-increasing population poses a serious challenge for agriculturalists around the world. Seed is a basic and critical input in agriculture to ensure global food security. Roughly 90 percent of the crops grown all over the world are propagated by seed. However, seed can also harbour and spread pathogens, e.g. fungi, bacteria, nematodes, viruses etc., which cause devastating diseases. Seed-borne pathogens represent a major threat to crop establishment and yield. Hence, timely detection and diagnosis is a prerequisite for their effective management. The book "Seed-Borne Diseases of Agricultural Crops: Detection, Diagnosis & Management" addresses key issues related to seed-borne/transmitted diseases in various agricultural crops. Divided into 31 chapters, it offers a comprehensive compilation of papers concerning: the history of seed pathology, importance of seed-borne diseases, seed-borne diseases and quarantine, seed health testing and certification, detection and diagnosis of seed-borne diseases and their phytopathogens, host-parasite interactions during development of seed-borne diseases, diversity of seed-borne pathogens, seed-borne diseases in major agricultural crops, non-parasitic seed disorders, mechanisms of seed transmission and seed infection, storage fungi and mycotoxins, impact of seed-borne diseases on human and animal health, and management options for seed-borne diseases. We wish to thank all of the eminent researchers who contributed valuable chapters to our book, which will be immensely useful for students, researchers, academics, and all those involved in various agro-industries.
Seed-borne plant virus diseases
by K. Subramanya SastrySeeds provide an efficient means in disseminating plant virus and viroid diseases. The success of modern agriculture depends on pathogen free seed with high yielding character and in turn disease management. There is a serious scientific concern about the transmission of plant viruses sexually through seed and asexually through plant propagules. The present book provides the latest information along with the total list of seed transmitted virus and viroid diseases at global level including, the yield losses, diagnostic techniques, mechanism of seed transmission, epidemiology and virus disease management aspects. Additional information is also provided on the transmission of plant virus and virus-like diseases through vegetative propagules. It is also well known that seed transmitted viruses are introduced into new countries and continents during large-scale traffic movements through infected germplasm and plant propogules. The latest diagnostic molecular techniques in different virus-host combinations along with disease management measures have been included. The book shall be a good reference source and also a text book to the research scientists, teachers, students of plant pathology, agriculture, horticulture, life sciences, green house managers, professional entrepreneurs, persons involved in quarantines and seed companies. This book has several important features of seed transmitted virus diseases and is a good informative source and thus deserves a place in almost all university libraries, seed companies and research organizations.
Seed Development: OMICS Technologies toward Improvement of Seed Quality and Crop Yield
by Ganesh K. Agrawal Randeep RakwalThe book is about the seed development in the model and crop plants. Seed development is a key step of the plant life cycle that determines the nutrient value of seeds - the life for human civilization, growth, and development. The nutrient value of seeds is mainly due to storage reserve products such as carbohydrates, lipids (triacylglycerols), and proteins. The book primarily focuses on application of the 21st century high-throughput technologies transcriptomics, proteomics, metabolomics, and systems biology in near complete understanding of the various processes involved in seed development in different crop plants. The book reveals how such technologies have revolutionized our understanding of the multilayer processes and regulations involved therein by generating large-scale datasets. Accumulated datasets provide basic knowledge to develop integrated strategies to eventually improve the nutritional value of plant seed and crop yield, a critical goal in food security issues around the globe.

Seed Endophytes: Biology and Biotechnology
by Satish Kumar Verma James Francis White JrThis book focuses on the importance and roles of seed microbiomes in sustainable agriculture by exploring the diversity of microbes vectored on and within seeds of both cultivated and non-cultivated plants. It provides essential insights into how seeds can be adapted to enhance microbiome vectoring, how damaged seed microbiomes can be assembled again and how seed microbiomes can be conserved. Plant seeds carry not only embryos and nutrients to fuel early seedling growth, but also microbes that modulate development, soil nutrient acquisition, and defense against pathogens and other stressors. Many of these microbes (bacteria and fungi) become endophytic, entering into the tissues of plants, and typically exist within plants without inducing negative effects. Although they have been reported in all plants examined to date, the extent to which plants rely on seed vectored microbiomes to enhance seedling competitiveness and survival is largely unappreciated. How microbes function to increase the fitness of seedlings is also little understood. The book is a unique and important resource for researchers and students in microbial ecology and biotechnology. Further, it appeals to applied academic and industrial agriculturists interested in increasing crop health and yield.
