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.
