Quantum mechanical problems capable of exact solution are
traditionally solved in a few instances only (such as the harmonic
oscillator and angular momentum) by operator methods, but mainly by
means of Schrodinger's wave mechanics. The present volume shows
that a large range of one- and three- dimensional problems,
including certain relativistic ones, are solvable by algebraic,
representation-independent methods using commutation relations,
shift operators, the viral, hyperviral, and Hellman-Feynman
theorems. Applications of these operator methods to the calculation
of eigenvalues, matrix elements, and wavefunctions are discussed in
detail. This volume provides an outstanding introduction to the use
of operator methods in quantum mechanics, and also serves as a
reference work on this topic. As such it is an excellent complement
to senior and graduate courses in quantum mechanics. Although
primarily a book on applications of operator methods, the
presentation is made self-contained by the inclusion of an
introductory chapter on the formalism of quantum mechanics.
Additional background material supplements the volume at various
points in the text. Although there has been much research on
operator methods to solve quantum mechanical problems, until now
many of these results have remained scattered throughout the
literature. Nonspecialists, as well as graduate and upper division
students in physics will find this accessible volume to be
essential reading in theoretical physics.
Now in its third year, the AVBOB Poetry Project has garnered several industry prizes.
I Wish I'd Said: Volume 2 includes 101 poems with English translations: 55 specially commissioned poems and 44 poems drawn from the 2018 competition. And, following the blueprint of the first volume, we pay homage to the Khoisan languages, by including two poems by the |Xam poet Dia!kwain. South African poets old and new were asked to submit poems on loss, grieving, love and consolation in their mother tongues.
This new collection – and the online poetry portal – forms a space where the voiceless may be heard, and where we find common ground. Loss is a universal language and poetry its voice.
Die meeste sterre is lankal dood is die bekroonde digter Johann de
Lange se dertiende bundel. Dit bestaan uit ses afdelings, deurgaans
gewy aan vlietende oomblikke vasgevang in 'n vers ("om met woorde die
onsegbare te sê"). Die bundel het 'n elegiese toonaard, en word
oorheers deur 'n bewustheid van verlies & verganklikheid, van
"inskaduwings van die lig". Verse oor die skryfproses figureer as
teenvoeter vir die verbygaande aard van mens wees. Dit is verse vir "my
mooi dooies". In "Oggendmusiek" beskryf die digter 'n vroegoggendkoor
van voëls voor sonsopkoms, elders 'n koorddanser, voetjie vir voetjie
oor die spantou. Soos in sy vorige werk is die erotiese verse 'n
hoogtepunt in die bundel, bv in "Ode aan die mielie": "Nét so, nog aan
die oggend tussen die syige bene van die dag staan hy, volryp,
pittig & reg."
Bloed & sneeu
Bloed op sneeu is ’n pasgebore rooi,
van iets gewond, ’n struikelende spoor.
En die sneeu? Is daar énigiets so mooi,
so prilwit gespits, as ’n haseoor?
This book presents new approaches to security risk analysis and
scenario building on the basis of water works such as flood
barriers and storm surge barriers. Defending flood barriers is not
only important because of climate change and rising sea levels, but
also due to the vulnerability of fresh water supplies and the
increasing number of people living in vulnerable low-lying river
and sea deltas.
Essentials of Body MRI extensively covers the field, offering clear
and detailed guidance on MRI as an invaluable tool for the primary
diagnosis and problem solving of diseases of the body, including
the abdomen, liver, pancreas, pelvis, heart, urinary tract, and
great vessels. The beginning chapters focus on the physics, pulse
sequences and other practical considerations related to body MR
imaging to help the reader fully understand the imaging appearance
of clinical disease. The remaining chapters discuss the clinical
applications, with the topics spanning from the normal anatomic
structures and diagnosis of abdominal, pelvic, cardiac and vascular
diseases to the modality's role as a tool for solving diagnostic
problems. The key points of each chapter are boxed as "Essentials
to Remember" for rapid review and learning. Written in clear,
accessible text, and featuring 887 figures and numerous tables,
Essentials of Body MRI is a resource that the radiology resident
and physician will turn to again and again.
NMR of Ordered Liquids gives a unique overview of the scope and
limitations of the NMR of oriented liquids, based on contributions
from acknowledged experts in the field. The book consists of four
sections:
-detailed general introduction which covers the basic principles
and sophisticated experimental techniques;
-wide variety of applications ranging from NMR studies of small
atoms and molecules in anisotropic liquids to the utilization of
residual dipolar couplings for structure determination of
biological molecules;
-summary of the sophisticated theoretical treatments, computer
simulations, and phenomenological models for anisotropic
intermolecular interactions that are widely used in the analysis of
experimental results;
-overview of the dynamical aspects and relaxation processes
relevant for orientationally ordered molecules.
Ignaz Maybaum (1897-1976) is widely recognized as one of the
foremost Jewish theologians of the post-Holocaust era. Although he
is mentioned in most treatments of post-Holocaust Jewish theology,
his works are out of print and are only accessible to a small
readership. Nicholas de Lange (who worked closely with Maybaum in
his lifetime), has made a representative selection from his
writings, under various headings: Judaism in the Modern Age,
Trialogue between Jew, Christian, and Muslim, the Holocaust, and
Zion. In an Introduction, he sets Maybaum's thoughts against the
background of their time, indicates their main lines, and assesses
how much of them is still of value today.
How can finite minds approach an infinite and ultimately unknowable
God? Is it true that Christianity is a religion of love and Judaism
a religion of law? Can a Jew accept the Orthodox Christian
veneration of holy images? How much do Jews and Orthodox Christians
have in common when they worship God? What can be done about
Christian prayers that Jews find offensive? How much responsibility
do Christians carry for antisemitism? These and other questions are
addressed in this book which is intended as a major contribution to
encounters between Judaism and Orthodox Christianity. In seventeen
chapters, expert theologians and historians examine central issues
of common concern relating to theology and worship as well as to
the vexed historical question of anti-Semitism. The focus is on
dialogue and deepened knowledge, as the contributors s dispel
widely-held misconceptions and identify a good deal of common
ground.
The development of new CNS drugs is notoriously difficult. Drugs
must reach CNS target sites for action and these sites are
protected by a number of barriers, the most important being the
blood-brain barrier (BBB). Many factors are therefore critical to
consider for CNS drug delivery, e.g. active/passive transport
across the BBB, intra-brain distribution, and central/systemic
pharmacokinetics, to name a few. Neurological disease and trauma
conditions add further complexity because CNS barriers, drug
distribution and pharmacokinetics are dynamic and often changed by
disease/trauma. Knowledge of all these factors and their interplay
in different conditions is of utmost importance for proper CNS drug
development and disease treatment. In recent years much information
has become available for a better understanding of the many factors
important for CNS drug delivery and how they interact to affect
drug action. This book describes small and large drug delivery to
the brain with an emphasis on the physiology of the BBB and the
principles and concepts for drug delivery across the BBB and
distribution within the brain. It contains methods descriptions for
studying drug delivery, routes and approaches of administering
drugs into the brain, the influence of disease, drug industry
perspectives, and a primer on neuroanatomy and physiological
considerations written specifically for drug delivery scientists.
Therewith, it contributes to an in-depth understanding of the
interplay between brain (patho)-physiology and drug
characteristics. Furthermore, the content is designed to be both
cutting-edge and educational, so that the book can be used in
high-level training of academic and industry scientists with full
references to original publications.

This 1949 novella about the violent expulsion of Palestinian
villagers by the Israeli army has long been considered a modern
Hebrew masterpiece, and it has also given rise to fierce
controversy over the years. Published just months after the end of
the 1948 Arab-Israeli War, Khirbet Khizeh (the 'kh' pronounced like
the 'ch' in 'Bach') was an immediate sensation when it first
appeared. Thousands of Israeli Jews rushed to read it, the critics
began to argue about it, and a Palestinian journalist in Nablus
described it as a sign that the Israeli army had a conscience and
that peace was possible. Since then, the book has continued to
challenge and disturb. The various debates it has prompted would
themselves make Khirbet Khizeh worth reading, but the novella is
much more than a vital historical document: it is also a great work
of art. Yizhar's haunting, lyrical style and charged registration
of the landscape are in many ways as startling as his wrenchingly
honest view of one of Israel's defining moments. Despite its
international reputation, this is the first UK publication of
Khirbet Khizeh.
Apart from an introductory chapter giving a brief summary of
Newtonian and Lagrangian mechanics, this book consists entirely of
questions and solutions on topics in classical mechanics that will
be encountered in undergraduate and graduate courses. These include
one-, two-, and three- dimensional motion; linear and nonlinear
oscillations; energy, potentials, momentum, and angular momentum;
spherically symmetric potentials; multi-particle systems; rigid
bodies; translation and rotation of the reference frame; the
relativity principle and some of its consequences. The solutions
are followed by a set of comments intended to stimulate inductive
reasoning and provide additional information of interest. Both
analytical and numerical (computer) techniques are used obtain and
analyze solutions. The computer calculations use Mathematica
(version 7), and the relevant code is given in the text. It
includes use of the interactive Manipulate function which enables
one to observe simulated motion on a computer screen, and to study
the effects of changing parameters.
The book will be useful to students and lecturers in undergraduate
and graduate courses on classical mechanics, and students and
lecturers in courses in computational physics.
This book introduces the concept of 'healthy healthcare' and posits
that this new concept is necessary in light of a shortage of
healthcare staff in the near future. Healthy healthcare implies
that healthcare systems are designed, managed and financed in
balance with the available resources to improve workers' health and
performance. Ultimately, a balanced perspective taking into account
the patient, the staff and the complex healthcare system will lead
to a more resource-efficient delivery of high-quality healthcare
services. The book synthesizes evidence-based practice and research
on the links between healthcare services, employee health and
wellbeing, and quality of healthcare from an interdisciplinary
perspective. Written by leading experts in this rapidly expanding
field of inquiry, this is the first book ever compiled on the
subject with such scope and breadth. It discusses how to conduct
interventions and research on healthy healthcare with different
populations and settings. The chapters critically examine the links
between these pillars; and identify research gaps in both
methodology and content from the perspectives of psychology,
medicine, nursing, economy, law, technology, management and more.
This innovative book is of interest to researchers and students of
health sciences, public health, health economics and allied
disciplines, as well as to stakeholders in the healthcare industry.

This open access book presents a selection of the best
contributions to the Digital Cities 9 Workshop held in Limerick in
2015, combining a number of the latest academic insights into new
collaborative modes of city making that are firmly rooted in
empirical findings about the actual practices of citizens,
designers and policy makers. It explores the affordances of new
media technologies for empowering citizens in the process of city
making, relating examples of bottom-up or participatory practices
to reflections about the changing roles of professional
practitioners in the processes, as well as issues of governance and
institutional policymaking.
The theme of Margaret M. De Lange's second book published by
Trolley is one of loneliness. It is a personal documentary, which
follows people close to her as well as some that she has met only
briefly, and the solitude they encounter.
Radical right-wing populist parties, such as Geert Wilders' Party
for Freedom, Marine Le Pen's National Front or Nigel Farage's UKIP,
are becoming increasingly influential in Western European
democracies. Their electoral support is growing, their impact on
policy-making is substantial, and in recent years several radical
right-wing populist parties have assumed office or supported
minority governments. Are these developments the cause and/or
consequence of the mainstreaming of radical right-wing populist
parties? Have radical right-wing populist parties expanded their
issue profiles, moderated their policy positions, toned down their
anti-establishment rhetoric and shed their extreme right
reputations to attract more voters and/or become coalition
partners? This timely book answers these questions on the basis of
both comparative research and a wide range of case studies,
covering Austria, Belgium, Denmark, Finland, France, the
Netherlands, Norway, Switzerland, and the United Kingdom. Analysing
the extent to which radical right-wing populist parties have become
part of mainstream politics, as well as the factors and conditions
which facilitate this trend, this book is essential reading for
students and scholars working in European politics, in addition to
anyone interested in party politics and current affairs more
generally.
