In the past ten years there was a worldwide trend towards increased
use of Tunnel Boring Machines (TBM's). This trend covers a broad
variety of applications ranging both from small diameters for
sewers and other utilities to large diameters for double track
railway and even three-lane highway tunnels. The response to this
has been the development of both hard rock machines in the
direction for application in soft ground, and soft ground TBM's to
be used in soft rock. Parallel to the technical development of
TBM's towards applications for longer tunnels, running through
changing geological conditions, there are needs for the development
of lining methods. 'TBM Tunnel Trends' an international lecture
serie collection, aims to present the latest scientific and
practical state of the art of TBM tunnelling, taking into
consideration interactions between machinery and lining. 26

The ASI Quarks, Leptons and Beyond, held in Munich from the 5th to
the 16th of September 1983 was dedicated to the study of what we
now believe are the fundamental building blocks of nature: quarks
and leptons. The subject was approached on two levels. On the one
hand, a thorough discussion was given of the status of our
knowledge of quarks and leptons and their interactions, both from
an experi mental and a theoretical standpoint. On the other hand,
open problems presented by the so called standard model of quark
and lepton interact ions were explored along various ways that lead
one beyond this frame work. One of the principal predictions of the
standard model is that weak interactions are mediated by heavy Wand
Z vector bosons. These particles were discovered in 1983 at CERN
and their relevant proper ties were discussed at the ASI by C.
Rubbia. Further theoretical predictions concerning these Z and W
bosons, yet to be checked by future experimentation, were discussed
by G. Altarelli with a view of seeing where the standard model
might fail and new physics ensue. The strong interactions of
quarks, based on Quantum Chromodynamics (QeD), are presumed to
cause the quarks to bind into hadrons. Pro gress in attempts to
calculate the observed hadronic spectrum, ab initio, starting from
QCD and employing lattice methods were reviewed at the ASI by P.
Hasenfratz.
The fourth volume of Progress in Orthopaedic Surgery is somewhat
different from pre vious publications of the series. The editors
have again tried to present two topics but the publications
presented from the European literature are of very recent origin.
In the age of total joint replacement it was felt to be imperative
to counteract the pre sent tendency to treat every joint which does
not seem to be healthy with an artificial re placement. Orthopaedic
surgery seems to be influenced by trends. In 1963, E. A. Nichol
discussing intracapsular hip fractures, quoted from Alice In
Wonderland in an editorial written for volume 45B of the Journal of
Bone and Joint Surgery "The Queen had only one way of settling all
difficulties, great or small, "Off with his head" ." Today one
could paraphrase his implied critizism by saying "Out with the
joint." No one doubts that joint replacements have been of great
value in treating degenerative joint changes, but it is already
apparent that replacement operations are not the ultimate answer
for treating every joint deformity. This volume represents the
European experience of different types of surgery in treat ing
arthrosis of the joints of the lower limb. A reader of the
Anglo-American literature will find suggestions in it which
reaffirm his uneasiness in considering only one solution for
problems concerning lower limb joints. I feel strongly that there
are other ways which allow a patient to function well with less
extensive operations."
Bacterial CpG-DNA sequences not only serve for genetic information
but act as "danger" signal to alert immune cells such as
macrophages and dendritic cells. CpG-DNA directly causes activation
of these members of the innate immune system yielding in
up-regulation of co-stimulatory molecules and pro-inflammatory
cytokines. As such they act as "natural" adjuvants to promote
protective Th1 polarized T cell immune responses. This book is the
first comprehensive review of the data emerging in this field.
Sleep Medicine is a rapidly growing and changing field. Experienced
sleep medicine clinicians and educators Richard B. Berry, MD and
Mary H. Wagner, MD present the completely revised, third edition of
Sleep Medicine Pearls featuring 150 cases that review key elements
in the evaluation and management of a wide variety of sleep
disorders. The cases are preceded by short fundamentals chapters
that present enough basic information so that a physician new to
sleep medicine can start reading page 1 and quickly learn the
essential information needed to care for patients with sleep
disorders. A concise, practical format makes this an ideal resource
for sleep medicine physicians in active practice, sleep fellows
learning sleep medicine, and physicians studying for the sleep
boards. Zero in on the practical, "case-based" information you need
to effectively interpret sleep studies (polysomnography, home sleep
testing, multiple sleep latency testing), sleep logs, and
actigraphy. Get clear, visual guidance with numerous figures and
sleep tracings illustrating important concepts that teach the
reader how to recognize important patterns needed to diagnose sleep
disorders. Confer on the go with short, templated chapters-ideal
for use by busy physicians. A combination of brief didactic
material followed by case-based examples illustrates major points.
Stay current with knowledge about the latest developments in sleep
medicine by reading updated chapters using the new diagnostic
criteria of the recently published International Classification of
Sleep Disorder, 3rd Edition and sleep staging and respiratory event
scoring using updated versions of the scoring manual of the
American Academy of Sleep Medicine Manual for the Scoring of Sleep
and Associated Events. Benefit from Drs. Berry and Wagner's 25+
years of clinical experience providing care for patients with sleep
disorders and educational expertise from presenting lectures at
local, regional and national sleep medicine courses. Dr Berry was
awarded the AASM Excellence in Education Award in 2010. Access the

In znodern pharznacognosy chemical and physical-cheznical methods
are being used znore and more for the investigation of medicinal
plants. This important fact and the increasing involvement of
chemistry, biocheznistry and botany in pllarmaceuti- cal,
znedicinal and general biological questions usher in a new epoch in
the disco- very of medicinal substances and the development of
drugs derived from the plant kingdom. One of the guiding ideas of
the first "Syznposiuzn on Pharznacognosy and Phytocheznistry" was
to promote these developments, to provide an additional sti- znulus
and to establish a basis for better coordination and cooperation.
The organizers intended that most of the modern branches of
research into natural products should be represented, including
analysis, structural chemistry, chemi- cal synthesis and
biosynthesis, as well as pharmacology. Since the plenary lectures
also reflect the present level of knowledge in some iznportant
areas of natural products research, this volume will constitute an
important source of information for an scientists interested in
natural substances. Its usefulness is much enhanced by the fact,
that the voluzne will appear only four znonths after the
Symposiuzn, thanks to the kind assistance of Dr. K. F. Springer of
Springer-Verlag. The organizers extend cordial thanks to an the
participants for their interesting contributions and herewith
invite them to attend the second Syznposium in 1973. We want to
express our special thanks to Miss Seitz and Miss Hagendorn for
their rapid and conscientious preparation of the manuscripts for
offset-printing.
Walter Wagner attempts to present a framework of understanding that
outlines the philosophy and theology of Fethullah Gulen, a
world-wide known scholar of Islam who inspired a global movement of
education and interfaith dialogue. This book shows how Gulen's
vision for the present and future makes the present and future
forms of Hizmet an essential part of his wider and urgent call for
the formation of a community of religiously committed and
non-religiously committed persons to work toward a just, equitable
and prosperous world now.

This thesis explores the benefits of flying in a tight formation,
mimicking the natural behavior of migratory birds such as geese.
The first phase of the research was to determine an optimal
position for the wingman of a tight formation flight of T-38 Talon
aircraft using the HASC95 vortex lattice code. A second wingman was
then added to determine the benefit derived by increasing formation
size. The second wingman was predicted to derive an even greater
induced drag benefit than the first wingman for T-38s operating at
Mach 0.54 at a 10,000-foot altitude. The predicted values were
17.5% savings for the second wingman versus 15% for the first
wingman. The flight test phase flew two and three-ship formations
to validate the computational work. The results of the two-ship
flight tests showed with 80% confidence that the wingman saved fuel
in the predicted optimal position (86% wingspan lateral spacing).
This position yielded actual fuel savings of 8.8% 5.0% versus the
predicted 15%. The other lateral positions did not show a
statistically significant fuel savings. The flight test team felt
that the three-ship formation data was inconclusive due to the
difficulty of trying to fly a stable position as the third aircraft
in the formation without station-keeping ability.
Competition for Army acquisition funding in the betrween wars
depression years was fierce. The opposing camps of Fighter
Supremacy versus Strategic Bombing played out at the Air Corps
Tactical School (ACTS), at GHQ, before Congress and in the media.
Military exercises pitted the Navy and the Air Corps in operations
with real cloak and dagger background gambits, each trying to gain
the upper hand. When leaders such as Benjamin Foulois, Billy
Mitchell, and Frank Andrews eventually were able to foster a bomber
competition to replace the Martin B-10, Boeing's four-engined Model
299 was a clear winner; but then it crashed at Dayton, and the Army
opted for the Douglas B-18. Somehow, Frank Andrews had enough faith
in his convictions and managed to have 13 Y1B-17s produced and sent
to the 2nd Bombardment Group at Langley Field, VA. There Robert
Olds and his three squadrons enthralled the country with long range
goodwill flights, transcontinental speed runs with an obscure 1st
Lt Curtis leMay navigating the way, and a thrilling movie "Test
Pilot" starring Clark Gable, Myrna Loy, and Spencer Tracy.
Fortunately for the trials of WWII, these daring young men of the
Army Air Corps put their careers on the line, and made the B-17 one
of the iconic weapons of that conflict. This is the untold story of
the aircraft development and the men who made it happen.
