Neutron imaging study of ‘pattern-welded’ swords from the Viking Age

We present novel imaging results from a non-invasive examination of three ‘pattern-welded’ swords from the Viking Age belonging to the National Museum of Denmark, using white beam and energy resolved tomographies with neutrons. Pattern-welded blades are made by forge welding together thin strips of iron and steel that were twisted and joined in various ways, producing a decorative pattern on the surface. The study shed light on the inner structure of the composite material and manufacturing techniques of these admired examples of past technology, revealing some otherwise invisible details of their assembly methods, phase distribution and extent of the corrosion.     

WHY DO WE CARE ABOUT POST‐HUMANISM? A CRITICAL NOTE

What is disclosed in the questioning of the human being in post‐humanism? Addressing this question in congruence with Heidegger's questioning of being in Being and Time, we end up with two discoveries: first, that the characteristic of Dasein, as the being of the questioning, already carries the same implications as the post‐human figure, and second, that questioning in this sense is indicative of the effort of realizing anew scientific space for conceptualizing the human being as non‐substantialist. Conceived of in this way, however, post‐humanism is a result of a very human effort indeed.     

Phenol Formaldehyde Revisited—Novolac Resins for the Treatment of Degraded Archaeological Wood

Archaeological wood is usually severely degraded. The Norwegian Viking Age Oseberg find exemplifies problems arising due to past conservation treatments and the need for new types of preservatives. Phenol formaldehyde (PF) has been investigated as a consolidant for alum‐treated wood. X‐ray tomography has revealed that it is possible to obtain a porous structure inside the wood, ensuring ethical acceptability by allowing re‐treatment. In order to understand the curing mechanics, the kinetics of the initial condensation reaction were elucidated at room temperature. It was found that a second‐order reaction using both phenol and formaldehyde concentrations is the most probable mechanism.     

Introduction

From the 15th to the early 18th century the Baltic Sea was not only a highway for the physical transport of basic goods, it also functioned as the channel for the import and local and regional transfer of foreign cultural artifacts, artisans, artists and a wide range of media for cultural diffusion. Established commercial transportation, especially to the Low Countries and the British Isles, of grain, timber and iron ore from Denmark, Sweden and the eastern Baltic states brought wealth to the social and political elites within the Baltic region. The economic prosperity of the higher social layers among the Baltic States allowed them as customers and patrons to import a wide range of objects of art and artifacts belonging to prestige culture. The contributors to this volume of the Scandinavian Journal of History address the cultural traffic outlined above. The volume's ten articles are revised versions of papers read at the conference Cultural Traffic and Cultural Transformation around the Baltic Sea, 1450–1720, a conference held in the Carlsberg Academy in Copenhagen in early spring 2003. The conference Cultural Traffic and Cultural Transformation around the Baltic Sea, 1450–1720 (Carlsberg Academy, Copenhagen, 21–22 March 2003,) was made possible by substantial grants from the Carlsberg Foundation (Denmark) and the Danish Research Council for the Humanities. Organizers Dr Badeloch Noldus (Instituut Pallas, Leiden University, The Netherlands) and Dr Stephen Turk Christensen (Department for History and Social Theory, Roskilde University Centre (RUC), Denmark) thank the following for their support: Dr David Gaimster (Ministry for Culture, UK), Curator Hugo Johannsen (Danish National Museum), Curator Steffen Heiberg (National Historical Museum Frederiksborg Castle), Dr Juliette Roding (Leiden University), Accounts Department (RUC), Department for History and Social Theory (RUC), the staff at Carlsberg Academy, Conference Assistant Thea Pedersen (RUC) and Dr Ole Meyer (University of Florence). The conference participants reflected upon and discussed questions relating to the nature, scope, origin, direction and impact of the cultural interaction taking place in the late medieval and Early Modern Baltic region with examples drawn especially, but not exclusively, from elite culture. For recent studies dealing with Early Modern cultural relations between mostly the Low Countries and areas within the western Baltic, see articles in J. J. van Baak, L. Honti & A. H. Huussen, eds. The Baltic. Languages and Cultures in Interaction (Proceedings NOMES-Conference, 19–20 May 1994); Tijdschrift voor Scandinavistiek, vol. 16 (1995); J. Roding & L. Heerma van Voss, eds., The North Sea and Culture (1550–1800). Proceedings of the International Conference held in Leiden, 21–22 April 1995 (Hilversum, 1996). An interesting, but uneven, treatment of the eastern Baltic within a wider context of cultural exchange can be found in M. Klinge, Östersjövälden. Et illustrerat historisk utkast (Borgå, 1985). Rather dispersed, and occasionally too categorically formulated, relevant information and contextualization concerning Baltic cultural interaction can be found in the general history of the territories of the western Baltic power states by D. Kirby, Northern Europe in the Early Modern Period. The Baltic World 1492–1772 (London & New York, 1990), especially in the section “Migrants, Aliens and the Problem of Religious Diversity”.      

The Green Frog and Desalination: A Nyungar Metaphor for the (Mis‐)Management of Water Resources,Swan Coastal Plain,Western Australia

ABSTRACT In common with Aboriginal groups around Australia, the indigenous people, or Nyungars, of Perth adopt a holistic attitude towards groundwater resources. Of cultural significance are lakes, springs, soaks and watercourses that feature in Dreamtime creation narratives. Perth is experiencing major water shortages and many Nyungars feel that the degradation of the freshwater supply is a result of mismanagement and unsustainable development by non‐Aboriginal people. Proposals for dealing with the issue are seen as equally out of balance with the natural order of things. Water regulators have much to learn from indigenous Australians about water and environmental management. Although water continues to be central to Nyungar identity, the study on which this article is based found evidence of attenuated knowledge about the Dreaming, with discontinuities evident in the way significance is increasingly being read in everyplace rather than in specific ‘story places’.
