Funeral service and insurance provider AVBOB, through its sponsorship of the AVBOB Poetry Project, gave South Africa the gentlest, most inclusive act of bereavement support in the form of an online poetry competition in all 11 official languages.

Poets submitted words of loss and consolation in all 11 mother tongues. Editors in all languages were carefully selected to curate the collection of poems entered, and they too were transformed by the process.

This is a poetry portal for all South Africans – a cathartic space where amateur and accomplished poets can use their craft to comfort others.

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.

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?

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.

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.

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.

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 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.

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. Chapter 24 of this book is available open access under a CC-By NC-ND 4.0 license at link.springer.com

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.

Hebrew manuscripts are our most important source of knowledge about Jewish medieval life, and anyone wishing to engage with Jewish history needs to know about the manuscripts, how to study them, and their literary genres. Colette Sirat offers a comprehensive overview of these subjects in this illustrated introduction. The book is a re-structured, extended and updated version of an earlier presentation in French. It has been translated from the author's revision of her earlier French book, and edited for an English readership, by Hebrew scholar Nicholas de Lange.

Johann de Lange, wat in 2011 die Hertzogprys vir poesie ontvang het vir sy bundel Die algebra van nood (2009), bevestig met hierdie bundel kwatryne sy meesterskap. Die bundel bestaan uit 100 kwatryne wat in ses afdelings verdeel is. Binne die klein bestek van vier reels kry De Lange dit telkens reg om kort flitse – byna soos weerlig – van betekenis aan die leser oor te dra. Dit is haas onmoontlik om die groot verskeidenheid temas wat in hierdie gedigte aangeraak word, saam te vat. Daar is liefdesverse, verse oor voels, plante, verwysings na ander skrywers wat wissel van die ou Grieke Theognis en Anakreon tot by Afrikaanse digters soos Joan Hambidge en Sheila Cussons, daar is kort besinnings oor verganklikheid en die tydloosheid van 'n by wat in amber gevang is, verlies en die dood. Bowenal demonstreer die digter hier op verbluffende wyse wat met die digtheid van digterlike taal vermag kan word.
