This book serves two purposes. The authors present important aspects of modern research on the mathematical structure of Einstein's field equations and they show how to extract their physical content from them by mathematically exact methods. The essays are devoted to exact solutions and to the Cauchy problem of the field equations as well as to post-Newtonian approximations that have direct physical implications. Further topics concern quantum gravity and optics in gravitational fields.
The book addresses researchers in relativity and differential geometry but can also be used as additional reading material for graduate students.

This book describes the full range of possible strategies for laterally aligning self-assembled quantum dots on a substrate surface, beginning with pure self-ordering mechanisms and culminating with forced alignment by lithographic positioning. The text addresses both short- and long-range ordering phenomena and introduces future high integration of single quantum dot devices on a single chip. Contributions by well-known experts ensure that all relevant quantum-dot heterostructures are elucidated from diverse perspectives.

Virtual Communion: Theology of the Internet and the Catholic Sacramental Imagination provides a theological account of the internet from a Catholic perspective. It engages digital culture by providing a context for media and mediation within the Catholic tradition, specifically focusing on the ecclesiology and sacramentality of the church. Katherine G. Schmidt argues that the Catholic imagination is inherently consonant with the idea of the "virtual," understood as the creative space between presence and absence, bringing the fields of media studies, internet studies, sociology, history, and theology together in order to give a theological account of the social realities of American Catholicism in light of digital culture. Overall, Schmidt argues that the social possibilities of the internet afford the church great opportunity for building a social context that allows the living out of Eucharistic logic learned in properly liturgical moments.

Common Heritage or Common Burden? contains a comprehensive and authoritative assessment of the US role in the negotiations on the UN Convention on the Law of the Sea and particularly in the negotiations on one of the remaining commons, the ocean floor beyond national jurisdiction. The author first examines the US view of the lawfulness of deep seabed mining under international law. He reviews the bureaucratic struggles, within the US Administration and the Congress, concerning the options to be pursued at the Conference; analyses the US position in the seabed negotiations from 1974 to 1980; and casts a fresh look both on the Reagan Administration's `policy review' of 1981-1982 which threatened the Conference's outcome, and current US oceans policy which remains an impediment to the Convention's early entry into force. The study suggests that despite significant compromises negotiated between the US and developing countries at the Conference up to 1980, the emerging seabed regime was not as widely endorsed by US officials as is generally assumed. Drawing on material collected from interviews with many key negotiators, the study contributes to a better understanding of domestic and international decision-making procedures and the dynamics of international negotiations.

This book expounds the theory of non-linear vibrations, a topic of great interest at present because of its many applications to important fields in physics and engineering. After introducing chapters giving the basic techniques for the study of non-linear systems the authors develop in detail the theory of selected topics encountered in their own work, presenting original material, approaches and results of analysis, and providing illustrations of useful applications.

Primary care medicine is the new frontier in medicine. Every nation in the world has recognized the necessity to deliver personal and primary care to its people. This includes first-contact care, care based in a positive and caring personal rela tionship, care by a single healthcare provider for the majority of the patient's prob lems, coordination of all care by the patient's personal provider, advocacy for the patient by the provider, the provision of preventive care and psychosocial care, as well as care for episodes of acute and chronic illness. These facets of care work most effectively when they are embedded in a coherent integrated approach. The support for primary care derives from several significant trends. First, technologically based care costs have rocketed beyond reason or availability, occurring in the face of exploding populations and diminishing real resources in many parts of the world, even in the wealthier nations. Simultaneously, the primary care disciplines-general internal medicine and pediatrics and family medicine-have matured significantly. They have become viable alternatives to the specialty approach to care with its potential dehumanization, coordination problems, and increased cost."

Accurate positioning of self-organized nanostructures on a substrate surface can be regarded as the Achilles heel of nanotechnology. This perception also applies to self-assembled semiconductor quantum dots. This book describes the full range of possible strategies to laterally align self-assembled quantum dots on a substrate surface, starting from pure self-ordering mechanisms and culminating with forced alignment by lithographic positioning. The text addresses both short- and long-range ordering phenomena and paves the way for the future high integration of single quantum dot devices on a single chip. Contributions by the best-known experts in this field ensure that all relevant quantum-dot heterostructures are elucidated from diverse perspectives."

Die Fachtagung PROZESSRECHNER 1977 setzt eine im Jahre 1974 in Karls- ruhe begonnene, wissenschaftliche Veranstaltungsreihe fort, die sich mit grundlegenden Fragen der ProzeBrechnertechnik, ihrem heutigenStand und ihrer Weiterentwicklung befaBt. Auch die zweite Fachtagung wurde wieder gemeinsam von der Gesellschaft fur Informatik, der Gesellschaft fur Kernforschung und der bei dieser Gelegenheit federfuhrenden VDI/VDE- Gesellschaft MeB- und Regelungstechnik ausgerichtet. In einer vorbereitenden Sitzung erzielte das Programmkomitee Uberein- stimmung daruber, das Tagungsprogramm bevorzugt auf die fur den ratio- nellen Einsatz der ProzeBrechner bedeutsamen Fragen der Software aus- zurichten. Bevorzugt behandelt werden solI ten fortschrittliche Metho- den zu Software-Produktion und -Betrieb, sowohl aus der Sicht des An- wenders wie des Systemherstellers. Dazu sollten auch Fragen der Wirt- schaftlichkeit und Standardisierung von Software einbezogen werden. Ferner erschien es wunschenswert, zu Beitragen aufzurufen, die uber neue Entwicklungen der Hardware und deren Einwirkung auf Systemstruk- tur und Software berichten. Die Resonanz, die der Aufruf zur Vortragsanmeldung bei Ingenieuren und Wissenschaftlern der anwendenden und herstellenden Industrie sowie der verschiedenen Forschungsinstitutionen fand, laBt sich aus dem vorlie- genden, umfangreichen Tagungsband ablesen. Er umfaBt neben den vier Hauptvortragen die 37, in sieben Themengruppen gegliederten Fachvor- trage der Veranstaltung. Wahrend die Hauptvortrage einen weitgespann- ten Uberblick auf die verschiedensten Aspekte der ProzeBrechnertechnik und ihrer Anwendung geben, zeichnen sich die uberwiegend praxisnahen Fachvortrage durch die Diskussion interessanter und neuartiger Losun- gen oder Losungsansatze fur die mannigfaltigen Probleme der ProzeB- rechner-Software undihrerRandgebiete aus.

From October 1964 to May 1969 the 40 MHz, 41 MHz, and 360 MHz signals of the satellite Explo 0 0 rer 22, were recorded at Lindau (51,650 N; 10,125 E). The Faraday effect recordings at 40 MHz and 41 MHz and Dispersive-Doppler-effect recordings at 40 MHz and 360 MHz were used to calculate the ionospheric electron content up to 1000 km. The mean electron content for 1 hour periods over a period 0 of three months as obtained at 51. 6 N geographic latitude as derived from various evaluation methods is presented. Furthermore, the relevant critical frequency FOF2 is displayed. A similar presentation was chosen for the calculated slabthickness data. For one specific case the daily variation of the electron con tent as determined by measurements was compared with a relevant theoretical curve. The agreement, was fairly good. Due to technical problems the beacons were switched off in 1969. Now the five orbiting FS-NNSS satellites provide a good possibility to determine the ionospheric electron content up to 1100 km fairly accurately by evaluating the Dispersive Doppler recordings obtained at 150 MHz and 400 MHz. The amplitude recordings of the 40 MHz and 41 MHz signals of Explorer 22 were furthermore used for amplitude scintillation studies. Simultaneous Dispersive-Doppler-recordings enabled in part also pha se scintillation studies. Phase and amplitude recordings were compared."

Lavishly illustrated with 200 new color photographs, drawings, maps, and charts, this concise and easy-to-use reference covers trees, shrubs, perennials, annuals, bulbs, grasses, and vines, and includes a plant selection guide for quick reference. The authors, whose combined experience spans six decades, take California's summer-dry climate and restricted water supplies into account and provide helpful notes on companion plants and gardening with wildlife. Practical and informative, "Growing California Native Plants" is a valuable reference for gardeners everywhere in California and an enjoyable book simply to explore.

Wahrend die Therapiekonzepte fUr die Akutphase des frischen Herzinfarktes, vor aUem die moglichst friih einsetzenden ReperfusionsmaBnahmen wie Lyse und Wie- dereroffnung des verschlossenen GefaBes heute wohl unbestritten sind, werden die therapeutischen MaBnahmen der Postinfarktperiode unterschiedlich beurteilt. Das gilt vor aUem fUr die Anwendung der Antiarrhythmika, denen man seit der CAST- Studie eher kritisch gegeniibersteht. Da aber gerade Herzrhythmusstorungen eine der Hauptkomplikationen und Todesursachen dieser Periode darstellen, haben die Ergebnisse dieser Studie zu einer erheblichen Verunsicherung der Arzteschaft ge- fUhrt. Bei aUer Skepsis soUte nicht vergessen werden, daB der therapeutische Nutzen von verschiedenen Medikamenten wie Betablockem, Kalziumantagonisten, Nitra- ten, Aggregationshemmem, Cumarinen auch in der Postinfarktperiode als gesichert gelten kann. Ebenso ist heute der Einsatz von ACE-Hemmem beim Auftreten einer Herzinsuffizienz unbestritten. Nur kann die Anwendung dieser Medikamente nicht verallgemeinert werden. Sie miissen vielmehr den individueUen Bediirfnissen des Patienten angepaBt werden. Das vorliegende Buch versucht aus der Sicht von Experten den heutigen Stand der medikamentosen Therapie der Postinfarktperiode kritisch darzulegen und zu diskutieren. Dem praktizierenden Arzt werden damit Richtlinien fUr die individu- eUe Betreuung des jeweiligen Patienten an die Hand gegeben. Er soUte aber nicht vergessen, daB es sich hier letztlich urn eine symptomatische Therapie bzw. urn die Behandlung von Komplikationen der koronaren Herzkrankheit handelt, deren Pdi- vention im aUgemeinen bzw. Repravention nach stattgehabtem Herzinfarkt durch Bekampfung der Risikofaktoren im Mittelpunkt seiner therapeutischen Uberlegun- gen stehen soUte.

Beim Nationenvergleich erhillt die Bundesrepublik Deutschland in der Re gel gute oder sehr gute Noten: sie ziihlt zu den wirtschaftlich reichen, politisch stabilen und in sozialpolitischer Hinsicht kompetenten Liindem. Bei den mei sten Industrielandervergleichen Dimmt die Bundesrepublik einen Platz im oberen Mittelfeld ein - etwa in der Sozialpolitik und beim Umweltschut- oder in der Spitzengruppe, beispielsweise bei der Inflationsbekiimpfung. In wirtschaftspolitischer Hinsicht ist die Bundesrepublik meist erfolgreicher als die englischsprachigen und die nordeuropiiischen Industrielander, und in der Sozialpolitik hat sie mittlerweile mit den skandinavischen Wohlfahrtsstaaten weitgehend gleichziehen konnen. Und im Hinblick auf Konfliktmanagement und sozialpartnerschaftliche Beziehungen zwischen Arbeit und Kapital wie auch hinsichtlich eines durch FOderalismus und Koaiitionsregierung gezugel ten Zentralstaates bildet die Bundesrepublik zusammen mit Osterreich und der Schweiz eine Liioder-Gruppe mit groBem Erfolg bei der Bewaltigung von Konfliktaustragungs- und Konsensbildungsproblemen. Doch nicht in allen Politikbereichen gehOrt die Bundesrepublik Deutschland zu den fiihrenden Liindem. Seit Mitte der 70er Jahre tut man sich hierzulande mit der Bewiiltigung von Arbeitslosigkeit schwer. Ebenso auffallend sind die Defizite der Bundesrepublik - und Gleiches gilt in dieser Hinsicht flir Oster reich und die Schweiz - bei der Eindammung geschlechtsspezifischer Un gleichheit. In wichtigen sozialen und wirtschaftlichen Bereichen haben Frauen hierzulande meist geringere Teilhabechancen als Manner und erheb lich geringere Teilhabechancen als in zahlreichen anderen westlichen Indu strieliindem."
