On September 11, 1814, an American naval squadron under Master
Commandant Thomas Macdonough defeated a formidable British force on
Lake Champlain under the command of Captain George Downie,
effectively ending the British invasion of the Champlain Valley
during the War of 1812. This decisive battle had far-reaching
repercussions in Canada, the United States, England, and Ghent,
Belgium, where peace talks were under way. Examining the naval and
land campaign in strategic, political, and military terms, from
planning to execution to outcome, The Battle of Lake Champlain
offers the most thorough account written of this pivotal moment in
American history. For decades the Champlain corridor - a direct and
accessible invasion route between Lower Canada and the northern
United States - had been hotly contested in wars for control of the
region. In exploring the crucial issue of why it took two years for
the United States and Britain to confront each other on Lake
Champlain, historian John H. Schroeder recounts the war's early
years, the failed U.S. invasions of Canada in 1812 and 1813, and
the ensuing naval race for control of the lake in 1814. To explain
how the Americans achieved their unexpected victory, Schroeder
weighs the effects on both sides of preparations and planning,
personal valor and cowardice, command decisions both brilliant and
ill-conceived, and sheer luck both good and bad. Previous histories
have claimed that the War of 1812 ended with Andrew Jackson's
victory at the Battle of New Orleans. Schroeder demonstrates that
the United States really won the war four months before - at
Plattsburgh on Lake Champlain. Through a comprehensive analysis of
politics and diplomacy, Schroeder shows that the victory at Lake
Champlain prompted the British to moderate their demands at Ghent,
bringing the war directly and swiftly to an end before Jackson's
spectacular victory in January 1815.
John H. Schroeder chronicles the expansion of the American Navy's
peacetime role in developing the nation's overseas commercial
empire during the thirty years before the Civil War. He
demonstrates how the rapid acceleration of American commercial
activity around the world increased pressure on the Navy to meet
new economic and political demands. He analyzes how the Navy's
haphazard development in the antebellum years paralleled and
interacted with commercial activity, and how the end result
impacted dramatically on the economic development of the United
States.
This volume represents the proceedings from a colloquium held in
West Germany in 1980 on late and postglacial oscillations of
glaciers. The main texts are in German (13), English (8) and French
(5) but all have abstracts in the three languages and all the
figure captions are similarly translated.
Previous symposia on Metabolic Interconversion of Enzymes were held
in 1970 (Santa Margherita-Ligure, Italy), 1971 (Rottach-Egern, Ger-
many), 1973 (Seattle, USA) and 1975 (Arad, Israel). The present
pub- lication reports the proceedings of the 5th International
Symposium on Metabolic Interconversion of Enzymes, held in
Titisee/Black Forest (Germany) from October 1st-5th, 1980. In the
last few years, the number of enzymes for which control of activity
by enzyme-catalyzed covalent modification, i.e., by intercon-
version, is of recognized metabolic importance has increased so
much that is was not possible to have every such enzyme considered
during a 3-day conference. The organizers therefore decided to
devote only one of the three sections to "metabolic
interconversion" per se, and to cover in the other two sections
"enzyme regulation by proteolytic modification" and "novel aspects
of regulation". According to the IUP AC-IUB Commission on
Biochemical Nomenclature (cf. J. Biol. Chem. 252,5939-5941 (1977)),
modification by proteolysis is not in- cluded in "metabolic
interconversion". Considering, however, the close interrelationship
of these two types of enzyme control, it has become a tradition,
beginning with the conference in Rottach-Egern 1971, to include
proteolytic modification in our conferences.
With the constant increase in applications involving image
processing and multimedia procedures digital signal processing
(DSP) is important for modern information engineering. One- and
Multidimensional Signal Processing provides an introduction to the
algorithmic basics of image and TV communication systems as well as
for systems in automation and robotic applications using sensor
based imaging techniques. This novel combination of both one- and
multidimensional signal processing discusses the similarities
between the two and aids the understanding of one theory over the
other.
* Presents an applications-oriented approach to image processing
including TV signal processing and discusses image scanning and the
use of DSP procedures or digital filters
* Provides clear and comprehensive coverage of basic concepts such
as spatial frequency, spatio-temporal signal processing and the
spectral representation of motion and tracking of moving
objects
* Features examples of applications including image pick-up and
display as well as still image filtering and image sequence
interpolation
* Introduces new design strategies for finite-impulse response
(FIR) filters for image processing applciations using spatial and
frequency design constraints
* Includes an introduction to nonlinear image processing
techniques applying edge detection operators, morphological
operators and rank order filters
Such a practical book will have wide-ranging appeal as a valuable
resource for researchers and developers and as an ideal
introductory text for senior undergraduate and postgraduate
students.

In den letzten 2 Jahrzehnten ist es gelungen, die einzigartige
Bedeutung des Stickstoffmonoxid (NO) fur eine Vielzahl von
biologischen Funktionen he rauszuarbeiten. Die Ergebnisse der
molekularbiologischen Forschung der letzten Jahre machen es
verstandlich, warum organische Nitrate seit Genera tionen
erfolgreich in der Akutbehandlung und Langzeitprophylaxe der Angi
na pectoris eingesetzt werden und ein unverzichtbarer Bestandteil
der phar makologischen Therapiemoglichkeiten bei der Behandlung der
koronaren Herzkrankheit sind. NO-Donoren aus der Gruppe der
Salpetersaureester sind Pro Drugs, die eine gestorte endogene, im
Wesentlichen endotheliale NO Produktion substituieren.
Ausgangspunkt fur die molekularbiologische For schung uber die
Wirkungen von NO waren die Ergebnisse der Forschungs arbeiten von
Robert F. Furchgott. Seine Arbeitsgruppe konnte auf Grund ex
perimenteller Untersuchungen die Existenz eines
"endothelium-derived relax ing factor" (EDRF) postulieren. Die
Gruppen von Salvator Moncada und Lou Ignarro konnten die Identitat
des EDRF mit dem NO-Radikal nachweisen. Sie erhielten dafur 1998
den Nobelpreis. Dies unterstreicht die hohe klinische Relevanz der
wissenschaftlichen Forschungsarbeiten mit NO. Die seit mehr als 100
Jahren therapeutisch eingesetzten organischen Nitra te haben auf
Grund der intensiven experimentellen pharmakologischen Ar beiten
das Stadium der Empirie verlassen und reprasentieren heute eine ra
tional begrundbare Substitutionstherapie. Fur die Wirkmechanismen
liegen experimentell sehr gut abgesicherte Modellvorstellungen vor.
Allerdings gibt es ungeachtet vieler grundsatzlicher
Gemeinsamkeiten innerhalb dieser Sub stanzklasse Unterschiede in
Wirkstarke, Wirkdauer sowie zu einem gewissen Ausmass auch im
Wirkort. Die pharmakokinetischen und pharmakodyna mischen
Unterschiede beruhen auf unterschiedlichen physikochemischen Ei
genschaften."
(1) Manche mogen die Aufnahme Marshalls in diese Liste anfech- ten
und wUrden Walras' Elements of Pure Economics (Origi- nal: Elements
d'economie politique pure, ou theorie de la richesse sociale) als
die profundere und logisch konsisten- tere Darstellung der
neoklassischen okonomischen Theorie vorziehen. In meinen Augen
fUhrte Marshalls Erkenntnis der Grenzen deduktiver Uberlegungen und
der Unmoglichkeit, ein auf wenigen grundlegenden Axiomen beruhendes
'reines Mo- dell' zu konstruieren, jedoch zu fruchtbareren
Resultaten als die eingleisige Verfolgung einer axiomatischen Wert-
theorie. (2) Die hier gewahlte Darstellung des Prinz ips weicht
etwas von Keynes' eigener in der General Theory abo (Sie gleicht
mehr Keynes' Ansatz im Treatise on Money (deutsch: Vom Gelde) .)
Die beiden sind jedoch aquivalent, weil die Investitionen die
Ersparnis aus 'Paktoreinkommen' Ubersteigen mUssen, da- mit die
Gewinne positiv sind. Keynes' Darstellungsweise in Kapitel 3 der
General Theory nahm keinen expliziten Bezug auf die wichtige Rolle,
die Gewinne als Anreiz und als Restquelle der Pinanzierung (oder)
Ersparnis fUr Investi- tionen spielen. (3) General Theory, Preface,
p. viii (4) VgI. Jukka Pekkarinen, On the Generality of Keynesian
Economics, Helsinki, 1979, p. 112. (5) Der Cambridger Tradition
folgend, schrieb Keynes die Glei- chung so, daB sie die Gleichheit
der Nachfrage Geld zu hal- ten mit dem verfUgbaren Angebot zeigt: M
= L (PY, r).
Die Pharmakologie, eine medizinische Hilfswissenschaft, sonnt sich
uberall auf der Welt in dem Anspruch, die rationa le Basis der
Therapie zu sein. Der Anspruch gerat allerdings ins Irreale, wenn
man sich die gegenwartige Ausbildung der deutschen Medizinstudenten
in Pharmakologie und Therapie mit Arzneimitteln vergegenwartigt:
die Grundlagen werden in zwei scheinpflichtigen Kursen wahrend des
Studiums im 1. und im 2. klinischen Abschnitt gelegt. Danach ist
keine wei tere obligate Unterweisung zur Nutzanwendung der Grundla
gen fur die Therapie vorgesehen. Dies steht im krassen Ge gensatz
zur Ausbildung in anderen therapeutischen Diszipli nen: wer mit dem
Messer oder dem Strahl therapeutisch um gehen will, braucht nach
der Approbation noch wenigstens eine 6-jahrige Weiterbildung. Wer
mit Pharmaka Therapie be treibt, solI nicht glauben, daB die in der
gegenwartig giiltigen Approbationsordnung vorgesehene Ausbildung
dafur ausrei chend ist. Diese Uberlegung ist wichtig, wenn man die
Bedeutung der "Einfuhrung in die klinische Pharmakologie zum
besseren Verstandnis der Arzneimitteltherapie" wiirdigen mochte: es
ist namlich dringlich notig, den praktisch tatigen Arzt mit der
rationalen Basis der Pharmakotherapie vertraut zu machen. Diese
Aufgabe kann ein Buch allein selbstverstandlich nicht bewaltigen.
Ihm sind schon dadurch Grenzen gesetzt, daB durch die rasche
Entwicklung neuer Arzneistoffe der prak tisch tatige Arzt immer
wieder in die Gefahr gerat, Opfer eines Informationsdeftzits zu
werden. Diese Argumentation ist al lerdings nur vordergriindig
betrachtet richtig. Wenn der Arzt dazu bereit ist, kann er durch
eine permanente Fortbildung auf dem laufenden bleiben."
