Sulke Vriende Is Skaars bevat die geannoteerde briefkorrespondensie tussen twee seminale figure in die Suid-Afrikaanse Westerse kunsmusiek. Dit is die eerste keer dat briefwisseling binne die Suid-Afrikaanse musiekgeskiedenisskrywing gepubliseer word en is ’n publikasie wat ’n noemenswaardige bydra tot die dissipline van Suid-Afrikaanse musiekhistoriografie, asook tot Afrikaner- en apartheidshistoriografie, sal maak.

Dit toon die belangrikheid aan van verdere navorsing oor die geïnstitusionaliseerde posisie van wit kunsmusiek in Suid-Afrika. Benewens die briewe, word belangrike foto’s, afskrifte van faksimilees, telegramme en ander vorme van korrespondensie geplaas en groot klem geplaas op die visuele voorkoms van die boek.

This book presents the design and manufacturing of microsystems as well as necessary key technologies developed within the Collaborative Research Center 516. The research efforts of this collaboration are focused on active micro systems which are based on the electromagnetic actuator principle. The travel of the investigated actuator systems is on the order of several millimeters. The total construction size of the actuator is on the range of several centimeters whereas essential structures being several micrometers. The methods and the production technologies that are investigated on the basis of various research models incorporate the fundamental process chains of microsystems.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

The earlier part of the commentary by 'Philoponus' on Aristotle's On the Soul is translated by William Charlton in another volume in the series. This volume includes the latter part of the commentary along with a translation of Stephanus' commentary on Aristotle 's On Interpretation. It thus enables readers to assess for themselves Charlton's view that the commentary once ascribed to Philoponus should in fact be ascribed to Stephanus. The two treatises of Aristotle here commented on are very different from each other. In On Interpretation Aristotle studies the logic of opposed pairs of statements. It is in this context that Aristotle discusses the nature of language and the implications for determinism of opposed predictions about a future occurrence, such as a sea-battle. And Stephanus, like his predecessor Ammonius, brings in other deterministic arguments not considered by Aristotle ('The Reaper' and the argument from God's foreknowledge). In On the Soul 3.9-13, Aristotle introduces a theory of action and motivation and sums up the role of perception in animal life. Despite the differences in subject matter between the two texts, Charlton is able to make a good case for Stephanus' authorship of both commentaries. He also sees Stephanus as preserving what was valuable from Ammonius' earlier commentary On Interpretation, while bringing to bear the virtue of greater concision. At the same time, Stephanus reveals his Christian affiliations, in contrast to Ammonius, his pagan predecessor.

The Life of Wilfrid offers us a graphic portrait of one of the most forceful characters in the history of the English Church: a man courageous and energetic yet at the same time litigious, ostentatious and overbearing, his life punctuated by restless travels and the most violent quarrels. Of noble birth, Wilfrid (c.634 709) gained his first experience of monastic life as a boy at Lindisfarne. Thereafter we find him at various times, crossing Gaul, staying in Lyons, visiting Rome, back in England at York, Ripon or Hexham, preaching to heathens in Sussex or Frisia, quarrelling with kings and bishops, imprisoned in Northumbria, again in Rome seeking papal support for his claims, founding monasteries in the Midlands and at last, in his old age, reconciled to those with whom he had earlier quarrelled so bitterly. Partisan but highly detailed, the Life was probably written within a decade of the saint's death. It is a remarkable account of a powerful personality who aroused affection and dislike in almost equal proportions.

Science is first and foremost an intellectual activity, an activity of thought. Therefore, how do we, as information scientists, respond intellectually to what is happening in the world of information and knowledge development, given the context of new sociocultural and knowledge landscapes? Information Science as an Interscience poses many challenges both to information science, philosophy and to information practice, and only when information science is understood as an interscience that operates in a multifaceted way, will it be able to comply with these challenges. In the fulfilment of this task it needs to be accompanied by a philosophical approach that will take it beyond the merely critical and linear approach to scientific work. For this reason a critical philosophical approach is proposed that will be characterised by multiple styles of thinking and organised by a compositional inspiration. This initiative is carried by the conviction that information science will hereby be enabled to make contributions to significant knowledge inventions that may bring about a better world. Chapters focus on the rethinking of human thinking, our unique ability that enables us to cope with the world in which we live, in terms of the unique science with which we are involved. Subsequent chapters explore different approaches to the establishment of a new scientific spirit, the demands these developments pose for human thinking, for questions of method and the implications for information science regarding its proposed functioning as a nomad science in the context of information practice and information work. Final chapters highlight the proposed responsibility of focusing on information and inventiveness and new styles of information and knowledge work.

Nagmusiek is a startling addition to contemporary South African fiction and biography. The book is both a scholarly study of the Afrikaans composer Arnold van Wyk and a work of fiction in which the author/biographer - who is and is not Stephanus Muller - highjacks his own literary undertaking. It is an extraordinary meditation on the art of biography, on South African classical music under the apartheid regime, and on the complicated relationship between life and fiction. Van Wyk’s musical composition, for which this book is named, is a ‘modernist poem of loss, of pain, of flickering memory, of dignified death’. Muller sets out to explore Van Wyk’s work and in the process creates an epic and genre-defying work of his own. This is an important book, a profoundly scholarly undertaking that will be a vital contribution to the field of Van Wyk studies in South Africa, but at the same time a groundbreaking work of experimental fiction. Stephanus Muller was raised in the Karoo and studied music and musicology at the universities of Pretoria, South Africa and Oxford. He teaches musicology at the University of Stellenbosch, where he is also the founder and head of the Documentation Centre for Music (DOMUS). He has published research and essays on many South African composers and is the co-editor of A Composer in Africa: Essays on the Life and Work of Stefans Grové (2006) and Gender and Sexuality in South African Music (2005).

The book "Case Studies in Micromechatronics - From Systems to Process" offers prominent sample applications of micromechatronic systems and the enabling fabrication technologies. The chosen examples represent five main fields of application: consumer electronics (pressure sensor), mobility and navigation (acceleration sensor), handling technology and automation (micro gripper), laboratory diagnostics (point of care system), and biomedical technology (smart skin). These five sample systems are made from different materials requiring a large variety of modern fabrication methods and design rules, which are explained in detail. As a result, an inverted introduction "from prominent applications to base technologies" is provided. Examples of applications are selected to offer a broad overview of the development environment of micromechatronic systems including established as well as cutting-edge microfabrication technologies.

Die Mikromechanik, die sich mit Entwurf, Herstellung und Anwendung von dreidimen- sionalen mechanischen Strukturen und Systemen mit Abmessungen im Mikrometerbe- reich befasst, hat in den vergangenen Jahren zunehmend an Bedeutung gewonnen und steht an der Schwelle zur breiten industriellen Anwendung. Ihr Einsatz fuhrt zu Quali- tats-und Leistungssteigerungen in vielen Bereichen der modernen Technik. An Stelle der konventionellen Fertigungsverfahren der Feinwerktechnik nutzt die Mikro- mechanik den Technologievorrat der Mikroelektronik, vor allem das Konzept der hoch- genauen Strukturubertragung mittels lithographischer Verfahren und das Konzept der kostengunstigen Fertigung in Batch-Prozessen. Die Mikromechanik kann daher als konsequente Weiterentwicklung der Mikroelektronik auf nicht-elektronische Gebiete be- trachtet werden. Die gemeinsame technologische Basis von Mikromechanik und Mikro- elektronik bietet gunstige Voraussetzungen fur die Integration mechanischer, optischer und elektronischer Funktionen zu komplexen Mikrosystemen. Die zur Zeit rasch anstei- gende Zahl von Publikationen zu diesem Thema zeigt die grosse Bedeutung, die dieser Entwicklung von Wissenschaft und Industrie beigemessen wird. Mikromechanische Bauelemente koennen durchaus in mittelstandischen Betrieben ent- wickelt und gefertigt werden. Wichtig ist jedoch, dass diese Betriebe Ingenieure als Mitarbeiter finden, die einen breiten UEberblick uber die Moeglichkeiten der Mikromecha- nik besitzen. Das vorliegende Buch moechte deshalb Studierenden, Anwendern in For- schung und Entwicklung sowie technisch interessierten Lesern eine Einfuhrung in die technologischen Grundlagen und die Anwendungen der Mikromechanik geben. Es ist aus einer Vorlesung entstanden, die ich seit 1986 an der Universitat Stuttgart fur Stu- denten der Fakultat Konstruktions-und Fertigungstechnik halte.
