Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- In this book several authors from the Nordic countries discuss the concept of identity as used within archaeology. Identity is as well part of the cultural heritage as an active component in today's political discussion. Ranging from present uses of identity today to the use of identity in the past, the 17 articles in the book show how identity works within archaeology.

Imaginary vessels in the Late Bronze age of Gotland and south Scandinavia : Ship settings, rock carvings and decorated metalwork
- 2010
-
Ingår i: Current Swedish Archaeology. - Stockholm : Swedish Archaeological Society. - 1102-7355. ; 18, s. 79-103
-
Tidskriftsartikel (refereegranskat)abstract
- The paper compares the Bronze Age ship settings of Gotland with the vessels portrayed in rock carvings on the Scandinavian mainland. It also makes comparisons with the drawings of vessels on decorated metalwork of the same period. It considers their interpretation in relation to two approaches taken to the depictions of ships in other media. One concerns the use of boats to transport the sun, while the other emphasises the close relationship between seagoing vessels and the dead. A third possibility concerns the distinctive organisation of prehistoric communities on Gotland. It seems possible that the largest of the ship settings were equivalent to the Bronze Age cult houses found on the mainland and that they may even have represented the island itself.

On the Correlation Between Microstructural Parameters and the Thermo-Mechanical Fatigue Performance of Cast Iron
- 2021
-
Ingår i: International Journal of Fatigue. - : Elsevier. - 0142-1123 .- 1879-3452. ; 145
-
Tidskriftsartikel (refereegranskat)abstract
- Strain-controlled out-of-phase thermo-mechanical fatigue tests at 100–500 °C and various strain ranges were conducted on five cast iron grades, including one lamellar, three compacted and one spheroidal graphite iron. Investigations of graphite morphology and matrix characteristics were performed to associate parameters, such as geometrical features of graphite inclusions and the matrix microhardness, to the thermo-mechanical fatigue performance of each grade. From this, thermo-mechanical fatigue life as a function of maximum stress at half-life, is found to decrease consistently with increasing average graphite inclusion length irrespective of the graphite content. In contrast, no evident correlation between the fatigue life and the matrix microhardness is observed.

Fatigue of Heavy-Vehicle Engine Materials : Damage Mechanisms, Laboratory Experiments and Life Estimation
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Due to increasing demands on sustainability exerted by end-costumers and policy makers, heavyvehicle manufacturers are urged to increase the engine efficiency in order to reduce the exhaust gas emission. However, increasing the efficiency is also associated with an elevated fatigue rate of the materials constituting the engine parts, which consequently reduces the engine service life. The aim of the present thesis is therefore to confront the expected increase by studying the fatigue behaviour and damage mechanisms of the materials typically employed in heavy-vehicle diesel engines. With this knowledge, this work seeks to guide the development of new heavy-vehicle engine materials, as well as to develop improved life estimation methods designated to assist the mechanical design of durable heavy-vehicle engines.In essence, a large set of thermo-mechanical fatigue (TMF) and combined thermomechanical and high-cycle fatigue (TMF-HCF) tests is conducted at engine load conditions on laboratory specimens of lamellar, compacted and spheroidal graphite iron. In this way, the fatigue performance and associated damage mechanisms are investigated. In particular, a new fatigue property is identified, the TMF-HCF threshold, which quantifies how resistant a material is to superimposed high-cycle fatigue.The damage mechanism at low temperatures (≲500°C) is confirmed to consist of the initiation, propagation and coalescence of numerous microcracks. Based on this, a successful fatigue life estimation model is formulated, allowing accurate estimations of TMF and TMF-HCF tests on smooth specimens, and TMF tests on notched specimens. In the latter case, the microcrack growth behaviour in non-uniform cyclic stress fields and its implications for life estimation are clarified. At elevated temperatures (≳500°C), surface oxidation is shown to govern the fatigue performance of cast iron grades intended for exhaust manifolds. It is observed that oxide intrusions are induced, from which surface fatigue cracks are initiated. Consequently, an optimal material at these conditions should have a low oxide growth rate and few casting defects at the surface, as these factors are found to stimulate the growth of intrusion.

Bokkapitel (refereegranskat)abstract
- In recent years, we have witnessed a tremendous increase in geochemical, biochemical, and biomolecular analyses on human remains that have given rise to new perspectives and interpretations on society, mobility, and interaction in prehistory (see below). The European Bronze Age seems increasingly to have been a dynamic world characterized by complex patterns of interaction at a local/micro-level as well as on a macro/continental scale. This work strives to demonstrate that there is potential for this complexity to be reflected in materials such as pottery, which has had a relatively marginal role in recent discourses about Bronze Age societies in Northern Europe. As we aim to show here, geochemical analyses of pottery can be used to add new layers of information to our knowledge about the period. The main objective of this paper is to publish the results of recent geochemical analyses conducted on a selected number of burial urns and ceramic grave goods from the Nordic Late Bronze Age burial ground of Simris 2 (see Stjernquist 1961). The analyses were carried out with the primary aim of determining the local or non-local origin of the raw materials used in the manufacture of the sampled items. As a secondary objective, our results are contrasted with the results of petrographic studies on the ceramic material from the Gualöv burial ground dated to Periods IV–V of the Nordic Bronze Age. Finally, this study demonstrates the potential that in-depth studies of ceramic production from southern Scandinavia may have for a deeper and more nuanced understanding of Late Bronze Age societies.

A Bronze Age ship made of stone. Record and analysis of a ship setting from Lau, Gotland

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- With only a few exceptions, the construction of the Bronze Age ship in Scandinavia has been interpreted mainly from twodimensional miniature depictions: rock-art and bronze artefacts. In this paper we add a third feature, the Bronze Age stone ship settings, and argue that they represent practical vessels, at least partly. With such a view a third dimension becomes observable and provides possibilities for discussion about a full-scale representation of a Bronze Age ship. Different components in ship construction are discussed and compared with details found in depicted ships on rocks and bronzes. The discussion is based upon an analysis of a ship setting in Lau Parish on the island of Gotland in the Baltic Sea, visited and recorded by the authors in April 2009.

- This paper discusses the occurrence of a number of axe images at Simrishamn in Scania and at Stonehenge in Wessex, all of which can bedated to the Arreton phase/Montelius’ period 1, 1750/1700–1500 BC. These two concentrations are the only major clusters of axe images in northern Europe dating to this time. In order to understand this situation a model is discussed, which implies that these two areas were linked by a network of people who traded in metal and amber. Amber collected along the coasts of the Baltic Sea went westwards, ending up as prestigious amber objectsin Wessex; in return metal was traded from England to south Scandinavia. The function and value of amber and metal was thus different in the two areas. It is argued that differences in the conceptualisation of metal are reflected in the ways axe images are arranged and displayed in Wessex and Scania.

Images of Shoes and Feet: Rock-Art Motifs and the Concepts of Dress and Nakedness
- 2013

Tidskriftsartikel (refereegranskat)abstract
- Feet and shoe images are a distinctive feature of Scandinavian rock art. They are life-size representations of parts of the human body but, in spite of this, they have rarely been incorporated into a discourse concerning human bodies in relation to the use of dress and nakedness in the construction of personhood. In this article this theme is elaborated by discussing images of feet and shoes primarily from Järrestad in south-east Sweden. It is argued that these images represented ideas of dress and nakedness and that these concepts were ambiguous and manifold: nakedness was used in certain social and ritual contexts to express authority and rank, while in other contexts nakedness was used to express community and equality.

Tidskriftsartikel (refereegranskat)abstract
- The Scandinavian landscape is littered with postglacial outcrops, many of which carry engraved motifs. Although drawings of ships are most often discussed, this paper focuses on representations of feet. In Northern Europe ship motifs are often associated with cosmologies based on the movement of the sun. This paper investigates whether drawings of feet could have been associated with the same worldview. A number of interpretations are offered of the images at two sites in different parts of Sweden: Järrestad 13:1 and Boglösa 138:1.

Iron Age Rock-Art: A View from Jarrestad in South-East Sweden
- 2013
-
Ingår i: European Journal of Archaeology. - : Cambridge University Press (CUP). - 1461-9571 .- 1741-2722. ; 16:4, s. 685-703
-
Tidskriftsartikel (refereegranskat)abstract
- This paper discusses the chronology of the Jarrestad rock-art site in south-east Sweden. Drawing on recent developments in ship chronology, it argues that images were produced from the very beginning of the Scandinavian Bronze Age, c. 1700 BC, to the earliest Iron Age, c. 200 BC. The images are not randomly spread, however, but cluster in two phases: c. 1700-1100 BC and c. 900-200 BC, each with its different characteristics. It is argued that the later phase should be viewed against the background of central and western European Hallstatt cultures which affected not only the iconography of the Jarrestad panel but also the organization of the surrounding cultural landscape.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The beginning of the Iron Age (Hallstatt C) at c. 800 BC marked an important event in European prehistory. One part of this change involved the introduction of new kinds of death rituals including the horse and wagon complex. New studies also demonstrate the presence of important changes in the locations of settlements in various regions across Europe. The strong impact of Oscar Montelius’ chronological scheme for the Scandinavian Bronze Age (which confined this period as one which ended c. 500 BC) has prohibited the formulation of a comparative European perspective on the Scandinavian material. However, large-scale rescue excavations have clarified the period surrounding 800 BC as an important time which functioned as a division between the organization of agriculture, settlements and landscapes in south and middle Sweden. This paper reviews these results against a wider European backdrop.

Rock art as history - representations of human images from a historical perspective

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The theme of this paper is to explore and discuss Scandinavian rock-art in a historical perspective. By discussing evidences from Early Bronze Age southeast Scania, this paper argues that rock art primarily had an integrative function in rituals, where the axe was an important symbol representing a broad aspect of society. The materials from Late Bronze Age northern Bohuslän points towards another direction; by the use of various attributes attached to human images different social roles are expressed in a much more straightforward way. It is argued that this reflect a larger trend in Europe around 800 BC as certain groups in society re-invented the tradition of using representations of humans in art to manifest aristocratic ideals.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This paper discusses rock art in south-east Scania, south-east Sweden. Chronological analysis indicates that the material is divided into four phases which start at c.1700 BC and end at c. 200 BC. It is argued that each of these phases had its own characteristics and that there were turning-points when the character of the rock-art tradition changed. The major conclusion is that there were no specific meanings attached to rock-art, but it was a medium used for different purposes over time as society changed.

Loss of SDHB Induces a Metabolic Switch in the hPheo1 Cell Line toward Enhanced OXPHOS

- Background: Enzymes of tricarboxylic acid (TCA) have recently been recognized as tumor suppressors. Mutations in the SDHB subunit of succinate dehydrogenase (SDH) cause pheochromocytomas and paragangliomas (PCCs/PGLs) and predispose patients to malignant disease with poor prognosis.Methods: Using the human pheochromocytoma cell line (hPheo1), we knocked down SDHB gene expression using CRISPR-cas9 technology.Results: Microarray gene expression analysis showed that >500 differentially expressed gene targets, about 54%, were upregulated in response to SDHB knock down. Notably, genes involved in glycolysis, hypoxia, cell proliferation, and cell differentiation were up regulated, whereas genes involved in oxidative phosphorylation (OXPHOS) were downregulated. In vitro studies show that hPheo1 proliferation is not affected negatively and the cells that survive by shifting their metabolism to the use of glutamine as an alternative energy source and promote OXPHOS activity. Knock down of SDHB expression results in a significant increase in GLUD1 expression in hPheo1 cells cultured as monolayer or as 3D culture. Analysis of TCGA data confirms the enhancement of GLUD1 in SDHB mutated/low expressed PCCs/PGLs.Conclusions: Our data suggest that the downregulation of SDHB in PCCs/PGLs results in increased GLUD1 expression and may represent a potential biomarker and therapeutic target in SDHB mutated tumors and SDHB loss of activity-dependent diseases.
