Fresh: A Perishable History

by Susanne Freidberg

That rosy tomato perched on your plate in December is at the end of a great journey—not just over land and sea, but across a vast and varied cultural history. This is the territory charted in Fresh. Opening the door of an ordinary refrigerator, it tells the curious story of the quality stored inside: freshness. We want fresh foods to keep us healthy, and to connect us to nature and community. We also want them convenient, pretty, and cheap. Fresh traces our paradoxical hunger to its roots in the rise of mass consumption, when freshness seemed both proof of and an antidote to progress. Susanne Freidberg begins with refrigeration, a trend as controversial at the turn of the twentieth century as genetically modified crops are today. Consumers blamed cold storage for high prices and rotten eggs but, ultimately, aggressive marketing, advances in technology, and new ideas about health and hygiene overcame this distrust. Freidberg then takes six common foods from the refrigerator to discover what each has to say about our notions of freshness. Fruit, for instance, shows why beauty trumped taste at a surprisingly early date. In the case of fish, we see how the value of a living, quivering catch has ironically hastened the death of species. And of all supermarket staples, why has milk remained the most stubbornly local? Local livelihoods; global trade; the politics of taste, community, and environmental change: all enter into this lively, surprising, yet sobering tale about the nature and cost of our hunger for freshness.

Freshman Lectures on Nanotechnology (Undergraduate Lecture Notes in Physics)

by Hassan Raza

Freshwater Crayfish Aquaculture in North America, Europe, and Australia: Families Astacidae, Cambaridae, and Parastacidae

by Jay Huner

Freshwater Crayfish Aquaculture in North America, Europe, and Australia is the first text to summarize the methods of culture for the eight most important crayfish species in the world. Methods developed to culture crayfishes around the world differ significantly, and this book enables readers to develop workable strategies for cultivating different crayfish species in specific environments. Huner and associate authors cover the following topics in detail: methods of crayfish culture crayfish diseases crayfish processing economics of crayfish cultureEach of the the three major crayfish industries are well-represented in this new book and special attention is given to the specific needs and accomplishments of each area, which is beneficial to producers in other countries. For example, while hatching technology has been important in Australia and Europe, it hasn?t yet been applied to any degree in North America. At the same time, North America has developed a major crayfish processing industry. Disease problems have resulted in more emphasis on that subject in Europe and yet it is vital to all involved in crayfish aquaculture. Businessmen, farmers, scientists, laymen, or students need to be exposed to the methods and problems associated with crayfish production in different parts of the world if they are to be successful in any crayfish project, whether it be research- or profit-oriented. Freshwater Crayfish Aquaculture in North America, Europe, and Australia is intended to provide all readers with one source of information on the subject of freshwater crayfish aquaculture.Professional staff, advanced students, and extension personnel will find the entire text beneficial. Those in corporate organizations and the agriculture field, especially decisionmakersin operations, will find the methods, markets, and financial considerations in this book a helpful guide.

Freshwater Crustacean Zooplankton of Europe

by Leszek A. Bledzki Jan Igor Rybak

This work provides a user-friendly, species level taxonomic key based on morphology, current nomenclature, and modern taxonomy using molecular tools which fulfill the most pressing needs of both researchers and environmental managers. This key arms the reader with the tools necessary to improve their species identification abilities. This book resolves another issue as well: the mix of female and male characters used in keys to the calanoid copepods. Often, during the identification process, both calanoid copepod sexes are not available, and the user of such a key is stuck with an uncertain identification. Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.

Freshwater Ecosystems: Revitalizing Educational Programs in Limnology

by Committee on Inland Aquatic Ecosystems

To fulfill its commitment to clean water, the United States depends on limnology, a multidisciplinary science that seeks to understand the behavior of freshwater bodies by integrating aspects of all basic sciences--from chemistry and fluid mechanics to botany, ichthyology, and microbiology. Now, prominent limnologists are concerned about this important field, citing the lack of adequate educational programs and other issues. Freshwater Ecosystems responds with recommendations for strengthening the field and ensuring the readiness of the next generation of practitioners. Highlighted with case studies, this book explores limnology's place in the university structure and the need for curriculum reform, with concrete suggestions for curricula and field research at the undergraduate, graduate, and postdoctoral levels. The volume examines the wide-ranging career opportunities for limnologists and recommends strategies for integrating limnology more fully into water resource decision management. Freshwater Ecosystems tells the story of limnology and its most prominent practitioners and examines the current strengths and weaknesses of the field. The committee discusses how limnology can contribute to appropriate policies for industrial waste, wetlands destruction, the release of greenhouse gases, extensive damming of rivers, the zebra mussel and other "invasions" of species-- the broad spectrum of problems that threaten the nation's freshwater supply. Freshwater Ecosystems provides the foundation for improving a field whose importance will continue to increase as human populations grow and place even greater demands on freshwater resources. This volume will be of value to administrators of university and government science programs, faculty and students in aquatic science, aquatic resource managers, and clean-water advocates--and it is readily accessible to the concerned individual.

Freshwater Inflows to Texas Bays and Estuaries: A Regional-Scale Review, Synthesis, and Recommendations (Estuaries of the World)

by Paul A. Montagna Audrey R. Douglas

Estuaries are defined by mixing of river and sea water, thus freshwater inflow is a key driver of estuary ecosystem structure and function. While there is much concern about water quality, there is much less about water quantity. As water is diverted for human use, less is flowing to the coast, which threatens estuary ecosystems. Some jurisdictions are now setting inflow standards, but there is no consensus on how to identify how much freshwater an estuary needs. There is a climatic gradient along the northwestern Gulf of Mexico coast and estuaries vary from hydrologically positive to neutral to negative, and this makes the Texas coast the ideal place to study how ecological processes vary with freshwater inflow. An estuary comparison approach is used in this open access work to examine hydrology, circulation, salinity, nutrients, carbonate, dissolved oxygen, plankton, nekton, benthos, and habitat dynamics and responses across varying hydrological regimes.

Freshwater Mollusks of the World: A Distribution Atlas

by Charles Lydeard and Kevin S. Cummings

The definitive resource on the biology and evolution of freshwater mollusks.There are more species of freshwater mollusks—well over 5,000—than all the mammal species of the world. Freshwater mollusks are also arguably the most endangered fauna on the planet. Yet few references exist for researchers, shell enthusiasts, and general readers who are interested in learning more about these fascinating creatures. In Freshwater Mollusks of the World, Charles Lydeard and Kevin S. Cummings fill that void with contributions from dozens of renowned mollusk experts.Touching on 34 families of freshwater gastropods (snails) and 9 families of freshwater bivalves (mussels and clams), each chapter provides a synthesis of the latest research on the diversity and evolutionary relationships of the family. The book also includes• a look at how evolving DNA sequencing data techniques help shed light on mollusk taxonomy• distribution maps of each family's biogeographic locales• a representative photo and distribution map for each of the freshwater mollusk families • the latest information on each family's conservation status—and how to reverse the habitat destruction, modification, and pollution that threatens it• a discussion of the ecological and economic damages caused by invasive mollusk species, as well as their role as disease vectorsMollusks provide us with amazing biogeographical insights: their ancient fossil record goes back over 500 million years, and their distribution patterns are a reflection of past continental and climate changes. The only comprehensive summary of systematic and biodiversity information on freshwater mollusk families throughout the world, this reference is a must for malacologists, limnologists, ichthyologists, stream ecologists, biogeographers, and conservation biologists.Contributors: Christian Albrecht, Rüdiger Bieler, Bert Van Bocxlaer, David C.

Freshwater and Marine Ecology

by Ulrich Sommer

Freshwater and Marine Ecology is an introduction to the field of aquatic ecology, integrating the conceptually and methodologically widely overlapping fields of limnology and biological oceanography. It is structured like most textbooks of general ecology, leading from more elemental entities (individuals having to cope with their environment) to increasingly overarching entities, from populations over communities and ecosystems to the biogeochemistry of the entire planet and, finally, an overview over the major human impacts on the aquatic components of the earth system. The book provides examples for all major theoretical concepts of general ecology while the usual ecology textbooks have a strong terrestrial bias and rely only on few aquatic examples. This book takes the contrasting approach, motivated by the fact the fact that life originated from aquatic systems and that surface waters cover more than 70% of the Earth’s surface. The choice of studies used as examplesin Freshwater and Marine Ecology provides a balanced mix of freshwater and marine studies, of field observations, experimental and modeling studies. The readers are confronted with very recent work leading to the forefront of contemporaneous research but also with classic studies which laid the foundations of theory development in the field. Freshwater and Marine Ecology is a comprehensive text ideally serving for undergraduate courses in biological oceanography, limnology, and ecology, but also for advanced students, teachers and scientists who had limited exposure to aquatic sciences and/or ecology during their studies.

Fretting Wear, Fretting Fatigue and Damping of Structures: Design Engineering Hand Book Learned from Failure Cases (Solid Mechanics and Its Applications #276)

by Toshio Hattori

This book provides a comprehensive overview of the mechanical distinctions between fretting damage under axial or bending external forces and fretting damage under a torsional load. It emphasizes the importance of studying practical accident cases to efficiently acquire technical skills. The book is structured around the fundamental technologies of material science, tribology, and mechanics, which are vital for understanding and addressing technical issues. The author has incorporated all fretting countermeasure technologies, which were previously often sensory and empirical in nature, and repositioned them as technologies grounded in fundamental principles. The book proposes an economical approach to product operation that maintains reliability by integrating not only design technology but also maintenance practices. It delves into specific materials, such as titanium alloys and aluminum alloys, which have seen increased use for weight reduction in industries like aerospace. In this book, “Critical Distance Stress Theory” that can easily derive the fatigue limit and fatigue life of the stress singular field at the contact edge was presented. As a result, the fretting fatigue strength and life can be predicted from the same FEM stress analysis as the normal stress concentration part. And finally, introducing a novel fretting mechanical model, the book focuses on scenarios where pressure force (N) and repeated tangential force (F) are applied to two planar objects, with the tangential force being transmitted solely through friction at the contact surface. This model finds relevance in turbine blade connection structures, among other applications. The author references Asai's research example, which encompasses fretting mechanical analysis, fretting wear evaluation, fatigue assessment, and structural damping evaluation using this model.
