This thesis investigates the effect of the magnetic field on
propagating surface plasmon polaritons (SPPs), or surface plasmons
for short. Above all, it focuses on using the magnetic field as an
external agent to modify the properties of the SPPs, and therefore
achieving active devices. Surface plasmons are evanescent waves
that arise at metal-dielectric interfaces. They can be strongly
confined (beyond the light diffraction limit), and provide a strong
enhancement of the electromagnetic field at the interface. These
waves have led to the development of plasmonic circuitry, which is
a key candidate as an alternative to electronic circuitry and
traditional optical telecommunication devices, since it is faster
than the former and less bulky than the latter. Adopting both a
theoretical and an experimental point of view, the book analyzes
the magnetic modulation in SPPs by means of an interferometer
engraved in a multilayer combining Au and Co. In this
interferometer, which acts like a modulator, the SPP magnetic
modulation is studied in detail, as are the parameters that have a
relevant impact on it, simple ways to enhance it, its spectral
dependence, and the highly promising possibility of using this
system for biosensing. The thesis ultimately arrives at the
conclusion that this method can provide values of modulations
similar to other active methods used in plasmonics.
Facing the current growing global archipelago of encampments, this
book project intends to develop a geographical reflection on 'the
camp', as a modern institution and as a spatial bio-political
technology. This book focuses on past and present camp geographies
and on the dispositifs that make them an ever-present spatial
formation in the management of unwanted populations characterizing
many authoritarian regimes as well as many contemporary
democracies. It also offers and investigates possible ways to
resist the present-day proliferating manifestations of camps and
'camp thinking', by calling for the incorporation of 'camp studies'
into the broader field of political geography and to consider the
geographies of the camp as constitutive of much broader modern
geo-political economies. By linking spatial theory to the
geopolitical and biopolitical workings and practices of
contemporary camps, the contributions in this collection argue that
the camps seem to be here-to-stay, like a permanent/temporary
presence giving shape to improvised, semi-structured and
hyper-orderly structured spatialities in our cities and our
countryside. Camps are also a specific response, for example, to
the changing conditions of European borders due to the 'refugee
crisis' and the rise of nationalism in many countries affected by
such crisis.

So you plan on majoring in Biology. Why wouldn't you want to use
what's been described as the best majors' text for learning the
subject? That's what you get with Solomon, Martin, Martin and
Berg's BIOLOGY. Working like a built-in study guide, the integrated
learning system guides you through the material, starting with key
concepts for each chapter and learning objectives for each section.
Check your grasp of key points before moving on by answering
Checkpoint questions at the end of each section. Reinforce your
understanding of the learning objectives with chapter summaries,
followed by the opportunity to test your new knowledge. To further
help you "get it," the eleventh edition uses themes--among others,
the evolution of life and the inter-relationship of structure and
function--as well as interactive online and multimedia resources.
Ready to go for it? Then go for BIOLOGY.
Die 8jahrige Hannah zieht mit ihren Eltern in ein altes Haus nach
Neuenburg. Schnell wird klar: Hier spukt's Nur gut, dass es Tante
Henny und den Gartner Gustav gibt. Die beiden wissen ja so viel
uber die alten Geschichten, die man sich hier uber das
geheimnisvolle Haus erzahlt. Gemeinsam mit ihren neuen Freunden
geht Hannah nicht nur dem Geheimnis ihres Hauses auf den Grund....
Solomon/Martin/Martin/Berg, BIOLOGY is often described as the best
majors text for LEARNING biology. Working like a built-in study
guide, the superbly integrated, inquiry-based learning system
guides you through every chapter. Key concepts appear clearly at
the beginning of each chapter and learning objectives start each
section. You can quickly check the key points at the end of each
section before moving on to the next one. At the end of the
chapter, a specially focused summary provides further reinforcement
of the learning objectives and you are given the opportunity to
test your understanding of the material. The tenth edition offers
expanded integration of the text's five guiding themes of biology
(the evolution of life, the transmission of biological information,
the flow of energy through living systems, interactions among
biological systems, and the inter-relationship of structure and
function) and innovative online and multimedia resources.
