This thesis describes novel approaches and implementation of
high-resolution microscopy in the extreme ultraviolet light regime.
Using coherent ultrafast laser-generated short wavelength radiation
for illuminating samples allows imaging beyond the resolution of
visible-light microscopes. Michael Zurch gives a comprehensive
overview of the fundamentals and techniques involved, starting from
the laser-based frequency conversion scheme and its technical
implementation as well as general considerations of
diffraction-based imaging at nanoscopic spatial resolution.
Experiments on digital in-line holography and coherent diffraction
imaging of artificial and biologic specimens are demonstrated and
discussed in this book. In the field of biologic imaging, a novel
award-winning cell classification scheme and its first experimental
application for identifying breast cancer cells are introduced.
Finally, this book presents a newly developed technique of
generating structured illumination by means of so-called optical
vortex beams in the extreme ultraviolet regime and proposes its
general usability for super-resolution imaging.
Terahertz (THz) radiation with frequencies between 100 GHz and 30
THz has developed into an important tool of science and technology,
with numerous applications in materials characterization, imaging,
sensor technologies, and telecommunications. Recent progress in THz
generation has provided ultrashort THz pulses with electric field
amplitudes of up to several megavolts/cm. This development opens
the new research field of nonlinear THz spectroscopy in which
strong light-matter interactions are exploited to induce quantum
excitations and/or charge transport and follow their nonequilibrium
dynamics in time-resolved experiments. This book introduces methods
of THz generation and nonlinear THz spectroscopy in a tutorial way,
discusses the relevant theoretical concepts, and presents
prototypical, experimental, and theoretical results in condensed
matter physics. The potential of nonlinear THz spectroscopy is
illustrated by recent research, including an overview of the
relevant literature.
"Concise Encyclopedia of Mexico" includes approximately 250
articles on the people and topics most relevant to students seeking
information about Mexico. Although the "Concise" version is a
unique single-volume source of information on the entire sweep of
Mexican history-pre-colonial, colonial, and moderns-it will
emphasize events that affecting Mexico today, event students most
need to understand.

Johann Georg Wille (1715-1808) was a German engraver from Hesse who
settled in Paris in 1736 and practiced his art there until his
death in 1808. He soon became the central figure in a wide-ranging
network of correspondents extending across Germany, Switzerland,
Italy and Denmark. His correspondence gives a precise chronology of
his relations with artists (A.R. Mengs, C.W.E. Dietrich), writers
(J.J. Winckelmann, S. Gessner), art patrons (C.L. von Hagedorn) and
visitors to Paris. As such it represents an important document on
European art and culture transfer in the second half of the 18th
century.
A sweeping tour of the infrared universe as seen through the eyes
of NASA's Spitzer Space Telescope Astronomers have been studying
the heavens for thousands of years, but until recently much of the
cosmos has been invisible to the human eye. Launched in 2003, the
Spitzer Space Telescope has brought the infrared universe into
focus as never before. Michael Werner and Peter Eisenhardt are
among the scientists who worked for decades to bring this historic
mission to life. Here is their inside story of how Spitzer
continues to carry out cutting-edge infrared astronomy to help
answer fundamental questions that have intrigued humankind since
time immemorial: Where did we come from? How did the universe
evolve? Are we alone? In this panoramic book, Werner and Eisenhardt
take readers on a breathtaking guided tour of the cosmos in the
infrared, beginning in our solar system and venturing ever outward
toward the distant origins of the expanding universe. They explain
how astronomers use the infrared to observe celestial bodies that
are too cold or too far away for their light to be seen by the eye,
to conduct deep surveys of galaxies as they appeared at the dawn of
time, and to peer through dense cosmic clouds that obscure major
events in the life cycles of planets, stars, and galaxies.
Featuring many of Spitzer's spectacular images, More Things in the
Heavens provides a thrilling look at how infrared astronomy is
aiding the search for exoplanets and extraterrestrial life, and
transforming our understanding of the history and evolution of our
universe.
Die Forderung wohltatiger und gemeinnutziger Zwecke durch Stifter
und Mazene hatte im Kaiserreich Hochkonjunktur. In der traditionell
stiftungsreichen Stadt Hamburg engagierte sich das alte
Handelsburgertum ebenso wie die vielen wirtschaftlichen Aufsteiger.
Michael Werner zeigt, welche Auswirkungen Krieg und Inflation, aber
auch die verstarkte staatliche Wohlfahrtspolitik in der Weimarer
Republik auf die Stiftungskultur hatten. Die totalitare
Staatsauffassung im Nationalsozialismus veranderte die
Rahmenbedingungen fur die Stiftungen noch einmal stark. So mussten
Strategien entwickelt werden, um sich der kompletten Vereinnahmung
durch den Staat zu entziehen."
'My concern is not to persuade people that they should stop eating.
My hope is that they will begin to change their way of thinking,
including the way they think about eating and drinking' - Michael
Werner. In 1923, Therese Neumann, a nun in Southern Germany,
stopped eating and drinking. Apart from the wafer given at Mass,
she did not eat again, despite living for a further 35 years. Other
similar cases have been reported over the years - often holy men
from the East - and have taken on something of a mythical status.
However, they remain obscure enough to be brushed aside by modern
scientists. Michael Werner presents a new type of challenge to
sceptics. A fit family man in his 50s, he has a doctorate in
Chemistry and is the managing director of a research institute in
Switzerland. In this remarkable account he describes how he stopped
eating in 2001 and has survived perfectly well without food ever
since. In fact, he claims never to have felt better! Unlike the
people who have achieved this feat in the past, he is an ordinary
man who lives a full and active life. Michael Werner has an open
challenge to all scientists: 'Test me using all the scientific
monitoring and data you wish!' In fact, he describes one such test
here in which he was kept without food in a strictly monitored
environment for ten days. Werner also describes in detail how and
why he came to give up food, and what his life is like without it.
This book features other reports from those who have attempted to
follow this way of life, as well as supplementary material on
possible scientific explanations of how one could 'live on light'.

We are not powerless over our addictions, nor are we helpless
victims of heredity, a disease, a spiritual malady, or a slew of
character defects that require the intervention of a "higher
power," and a lifetime of meetings to control. Studies show that
75% of all addicts recover on their own, without pills, patches,
rehabs, or self-help groups. How many people do you know who
successfully quit smoking "cold turkey," without artificial aids or
programs, and nicotine is one of the most addictive substances on
earth.
People can recover on their own because they find ways of
addressing the learned aspects of addiction that are driven by our
reward system. Almost any activity we find pleasurable, from eating
a chocolate chip cookie to hearing great music or seeing a
beautiful face, can activate the reward system. Once aroused, these
circuits enable our brains to encode the circumstances that led to
the pleasure, so we can repeat the behavior and the reward in the
future.
Over time, the pleasure becomes misery, but we now have little
choice but to continue because the behaviors and belief systems
that drive our addiction have become well-learned, deeply ingrained
habits. The journey to addiction begins with our receiving positive
reinforcement from use of the drug - it makes us feel good, and
ends with the "gotta have its" screaming in our ear. For some, it
seems like a hopeless situation, but the vast majority of us find a
solution to the problem, and so can you.
Just as we learn to become addicted, we can learn to make the
necessary changes to our thoughts and beliefs that will relieve us
of the burden of our addictions for a lifetime, not just a
day-at-a-time. Powerless No Longerwill help you learn to take
advantage of your brain's natural ability to rewire itself, its
neuroplasticity, to overcome your addictive behavior and reach your
full potential.
Powerless No Longer is for anyone who is concerned about an
addictive behavior problem and is looking for help deciding upon a
course of action. The book introduces a newcomer to the science of
addiction, the process of change, and specific methods and tools
that offer a way out.
If you are questioning your own drug and alcohol use, or have
tried 12-step programs and not succeeded, Powerless No Longer is
for you. If you believe you are "powerless" over your addiction,
you will see evidence proving that this is not true. Powerless
explains the self-change methods that work for the majority of
addicts who recover on their own, and shows you how to apply these
principles in your own recovery. Powerless combines in one
place:
- A detailed explanation of the bio/psycho/social aspects of
addiction
- The research and studies that show how most people recover
- A comprehensive review of current recovery methods, and
- Suggestions you can use to take what's available and build a
recovery program that fits your own needs
There is no single drug, method, or program that works for
everyone under all conditions and circumstances. In other words,
there is no "silver bullet" for addiction, and Powerless No Longer
doesn't claim to be one either. There are almost as many paths to
successful recovery as people who have recovered, and no single
group or method has the only ticket. However, there are certain
commonalities in the methods used by study subjects who quit on
their own, and a huge body of scientific evidence indicating what
does work for most people most of the time. That's what you will
find in Powerless No Longer-choices, not a rigid framework of
inflexible dogma.
You do need to tap into a source of power and strength, but it
isn't outside, it's internal. If you possess a genuine desire to
effect self-change, you have within yourself all the power you
need, and PNL can help you unlock it.
Golf stories are funny, caddie stories are hilarious Caddy Tales is
proof of this statement. Scott has done an outstanding job of
putting a few of his actual caddying experiences on paper which
allows the reader to feel like they are sitting in the same room
reliving the stories. These tales capture the comedy that ensues
when the golf gods shake the elite and private members to their
core. 33 million people play golf in the United States every year,
yet less than 1% of them will have ever taken a caddie. The 99 %
that do take caddies are not your PGA Tour Pro's or Professional
golfers. They are members and resort guests that shoot an average
of 95. Caddy Tales is a unique one of a kind book which tells the
hysterical stories that develop when people from all walks of life
take a caddie.
