This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
This book was triggered by the success story of sector field mass spectrometry in elemental and isotopic analysis from the early days when the first mass spectrum of Ne was presented a hundred years ago. The outstanding and unique features of sector field mass spectrometry - high sensitivity, high mass resolution and simultaneous multiple ion detection - paved the way for its successful and increasing application in different fields of science. Written, compiled and edited by worldwide renowned experts with profound expertise in sector field mass spectrometry related to elemental and isotopic analysis, this book is intended to provide deep insight into the topic along with fundamental knowle...
This volume brings together extended reviews and papers of new scientific research on atmospheric nitrogen deposition impacts globally. While there is a wealth of evidence on the magnitude, components and effects of nitrogen disposition on floral biodiversity in Europe and North America, there is an obvious lack of information on impacts on above- and below-ground fauna, and all impacts in other parts of the world, with no clear overview of how the different strands of evidence fit together. This overall synthesis is targeted at the international conventions, but is equally readable for scientists, environmental managers, conservation agencies and policy makers. 'This timely book highlights ...
Anthropogenic emissions of ammonia cause a host of environmental impacts, including loss of biodiversity, soil acidification and formation of particulate matter in the atmosphere. Under the auspices of the UNECE Convention on Long Range Transboundary Air Pollution, around 80 international experts met to review the state of scientific knowledge. This book reports their analysis. It concludes that threshold levels for ammonia effects have been underestimated and sets new values, it assesses the independent evidence to verify reported reductions in regional ammonia emissions, and it reviews the uncertainties in modelling ammonia, both in "hot spots" and at the regional scale.
Nitrogen is the most yield-restraining nutrient in crop production globally. Efficient nitrogen management is one of the most important factor for improving nitrogen use efficiency, field crops productivity and profitability. Efficient use of nitrogen for crop production is therefore very important for increasing grain yield, maximizing economic return and minimizing nitrous oxide (N2O) emission from the fields and nitrate (NO3) leaching to ground water. Integrated nitrogen management is a good strategy to improve plant growth, increase yield and yield components, grain quality and reduce environmental problems. Integrated nitrogen management (combined use of chemical + organic + bio-fertilizers) in field crop production is more resilient to climate change.
Protected designation of origin (PDO) taken together with other geographical indicators, such as protected geographical indication (PGI) and traditional specialty guaranteed (TSG), offer the consumer additional guarantees on the quality and authentication of foods. They are important tools that protect the names of regional foods, such as wines, cheeses, hams, sausages and olives, so that only foods that genuinely originate in a particular region are allowed to be identified as such. The economic value of these regional foods, as well as the increased interest from consumers and the food industry about the traceability and origin of food, mean that it has become necessary to establish method...

This book is the first detailed analysis of an exquisitely illuminated thirteenth-century Parisian manuscript (The Royal Library, Copenhagen) which was owned by Christina of Norway (1234-1262), daughter of Håkon IV and wife of Philip of Castile and León. New information is provided about the Psalter?'s medieval and later components, its liturgical and other functions, missing illuminations and texts, as well as its provenance and date. Furthermore, the stylistic and iconographic similarities between the Psalter and some of the most important manuscripts illuminated in Paris in the Period, like the three-volume Moralized Bibles, are discussed. Suggestions also are made about the meanings the texts and images might have had for their intended audience.
The 20th century has experienced environmental changes that appear to be unprecedented in their rate and magnitude during the Earth's history. For the first time, Stable Isotopes as Indicators of Ecological Change brings together a wide range of perspectives and data that speak directly to the issues of ecological change using stable isotope tracers. The information presented originates from a range of biological and geochemical sources and from research fields within biological, climatological and physical disciplines covering time-scales from days to centuries. Unlike any other reference, editors discuss where isotope data can detect, record, trace and help to interpret environmental change. - Provides researchers with groundbreaking data on how to predict the terrestrial ecosystems response to the ongoing rapid alterations - Reveals how ecosystems have responded to environmental and biotic fluctuations in the past - Includes examples from research by a wide range of biological and physical scientists who are using isotopic records to both detect and interpret environmental change
The mythological, folkloric, and religious beliefs of Western culture have resulted in a long and ongoing history of esoteric themes in theatre from the Middle Ages to the present in Spain and the America. Now Robert Lima, a noted comparatist, brings to bear on this material his wide knowledge of the world of the occult. Lima defines the terms "occult" and "occultism" broadly to embrace the many ways in which humans have sought to fathom a secret knowledge held to be accessible only through such supernatural agencies as alchemy, angelology, asceticism, astrology, demonolatry, divination, ecstasy, magic, necromancy, possession, Santeria, séances, voudoun, and witchcraft. The dramatic works covered range from medieval materializations of Hell to the Golden Age plays of Lope de vega, Tirso de Molina, and Calderón de la Barca, to modern stage works by Valle-Inclán, García Lorca, Casona, Miras, and a number of significant Afro-Brazilian and Caribbean dramatists. The concluding comprehensive bibliography of the drama of the occult is invaluable.
