Upon its initial publication more than fifteen years ago, this book broke new ground with its comprehensive coverage of the biology and ecology, distribution and dispersal mechanisms, physiology, monitoring, negative and positive impacts, and control of aquatic invasive species of mussels, clams, and snails. Building on this foundation, the second edition of Monitoring and Control of Macrofouling Mollusks in Fresh Water Systems includes completely revised information on species such as the zebra mussel while also covering up-and-coming nuisance species such as the quagga mussel, Conrad s false mussel, the Asian clam, and the fast-spreading golden mussel.

The Second Edition includes:

• Ten new species of mussels and snails
• International case studies on mussel fouling problems and how to cope with them
• New control and monitoring techniques
• Discussions of the latest threats and possible future scenarios

The book contains brief descriptions of the external and internal structures, examining only those features relevant to the monitoring and control of the invasive species. It discusses why the mollusks are pests, distinguishing nuisance species from native species, their habits and habitat, reproductive potential, and life cycles and population dynamics. The authors also explain how efficient dispersal mechanisms employed by the nuisance mollusks not only help them spread so rapidly to inland lakes and rivers across continents, but how they can invade virtually every part of a facility.

While many other resources contain segments of this information, none cover all areas and link them in a cohesive fashion. It is this approach that makes the understanding of potential impacts on ecosystems, industries and utilities, as well as the many human-made physical and chemical mitigants for controlling the mollusks supplied by this book so crucial for preserving the health of raw water supplies.

In 1896, a young Genevan medium named Hélène Smith perceived in trance the following words from a Martian inhabitant: "michma michtmon mimini thouainenm mimatchineg." Those attending her séance dutifully transcribed these words and the event marked the beginning of a series of occult experiences that transported her to the red planet. In her state of trance, Smith came to produce foreign conversations, a new alphabet, and paintings of the Martian surroundings that captured the popular and scientific imagination of Geneva. Alongside her Martian travels, she also retrieved memories of her past lives as a fifteenth-century "Hindoo" princess and as Queen Marie Antoinette. Today, Smith's séances may appear to be nothing more than eccentric practices at the margins of modernity. As author Claudie Massicotte argues, however, the medium came to embody the extreme possibilities of a new form of subjectivity, with her séances becoming important loci for pioneering authors' discoveries in psychology, linguistics, and the arts. Through analyses of archival documents, correspondences, and publications on the medium, Massicotte sheds light on the role of women in the construction of turn-of-the-century psychological discourses, showing how Smith challenged traditional representations of female patients as powerless victims and passive objects of powerful doctors. She shows how the medium became the site of conflicting theories about subjectivity—specifically one's relationship to embodiment, desire, language, art, and madness—while unleashing a radical form of creativity that troubled existing paradigms of modern sciences. Massicotte skillfully retraces the story of this prolific figure and the authors, scientists, and artists she inspired in order to bring to light a forgotten chapter in modern intellectual history.

In the globe-spanning chronicle of an unprecedented historic event, journalists and photographers share an extraordinary collection of stories of the COVID pandemic: from the isolation and devastation of quarantine to the joy of reunion. As COVID-19 continued to evolve and impact communities around the globe, the National Geographic Society launched a Global Emergency Fund for Journalists to cover this extraordinary crisis within their own communities. The fund put a particular emphasis on delivering news to under served populations, particularly where there is a dearth of evidence-based information getting to those who need it. This pandemic has made evident the vulnerability, inequity, and the many environmental injustices in our society, but it has also shown us the incredible resilience of many communities. Selections from this powerful body of work will be featured in a global travelling exhibition entitled "Inside the Curve: Stories from the Pandemic." The book, which will extend and amplify the exhibition, will illuminate some of the themes of the crisis that have impacted all of us, as well as unique stories of heroism and survival.

Dieses Buch handelt von 20 geometrischen Figuren (Icons), die eine wichtige Rolle bei der Veranschaulichung mathematischer Beweise spielen. Alsina und Nelsen untersuchen die Mathematik, die hinter diesen Figuren steckt und die sich aus ihnen ableiten lasst. Jedem in diesem Buch behandelten Icons ist ein eigenes Kapitel gewidmet, in dem sein Alltagsbezug, seine wesentlichen mathematischen Eigenschaften sowie seine Bedeutung fur visuelle Beweise vieler mathematischer Satze betont werden. Diese Satze umfassen unter anderem auch klassische Ergebnisse aus der ebenen Geometrie, Eigenschaften der naturlichen Zahlen, Mittelwerte und Ungleichungen, Beziehungen zwischen Winkelfunktionen, Satze aus der Differenzial- und Integralrechnung sowie Ratsel aus dem Bereich der Unterhaltungsmathematik. Daruber hinaus enthalt jedes Kapitel eine Auswahl an Aufgaben, anhand derer die Leser weitere Eigenschaften und Anwendungen der Diagramme erkunden koennen. Das Buch ist fur alle geschrieben, die Freude an der Mathematik haben; Lehrkrafte und Dozenten der Mathematik werden in diesem Buch sehr nutzliche Beispiele fur Problemloesungen sowie umfangreiches Unterrichts- und Seminarmaterial zu Beweisen und mathematischer Argumentation finden.

What do the Mona Lisa, the light bulb, and a Lego brick have in common? The answer - intellectual property (IP) - may be surprising, because IP laws are all about us, but go mostly unrecognized. They are complicated and arcane, and few people understand why they should care about copyright, patents, and trademarks. In this lustrous collection, Claudy Op den Kamp and Dan Hunter have brought together a group of contributors - drawn from around the globe in fields including law, history, sociology, science and technology, media, and even horticulture - to tell a history of IP in 50 objects. These objects not only demonstrate the significance of the IP system, but also show how IP has developed and how it has influenced history. Each object is at the core of a story that will be appreciated by anyone interested in how great innovations offer a unique window into our past, present, and future.
