One of the greatest challenges for the archaeology of ritual and religion is to find ways to connect theoretical developments with the archaeological record. This article explores the possibilities of synchronizing archaeological methods and theories in our search for understanding ritual in the past through a concrete case study of a Mesolithic cemetery in Southern Scandinavia. The author argues
Popular Abstract in Swedish Akut pankreatit (bukspottkörtelinflammation) drabbar årligen cirka 300 individer per miljon invånare i Sverige. Dödligheten ligger totalt på cirka 4-7 % och betydligt högre, cirka 20 %, vid svår nekrotiserande pankreatit. Mortaliteten är vanligen associerad med multipel organsvikt och korrelerad till storleken på det inflammatoriska svaret. Underliggande mekanismer för Acute pancreatitis (AP) is a common disorder where underlying mechanisms for the local initiating events in the pancreas, the systemic dissemination of the inflammatory response and the remote organ dysfunction still are unclear. The aim of the present study was to further characterize the dynamics and sequence of the immune response in AP, and to determine the cellular origin of the initiating ev
The lichen flora of the Nordic countries, containing about 2,000 species, is regarded as one of the best known in the world. Lichenological research of the region has been continuous since the time of Erik Acharius (1757-1819), the 'father of lichenology', but there is no modern treatment of the region's impressive lichen flora. The last attempt was made in the 1870s by Th. M. Fries, but his major
The enlargement of the European Union provides opportunities for members to be mobile in seeking various forms of permanent and non-permanent employment, particularly temporary work and contract labour. These changing conditions require quick reactions, overcoming soft issues such as language barriers and coping with culture clashes and political issues that could create problems for the worker. W
Popular Abstract in Swedish För att förstå på vilket sätt viktiga pollinerande insekter påverkas av det omgivande landskapets struktur och innehåll, har jag studerat populationer av humlor (fam. Bombus). Jag har också gjort en analys av sambandet mellan jordbruksintensitet of landskapets komplexitet. Mina studier har utförst i Skåne och jag har valt studieområden bl.a. baserat på hur stora åkrar oTo investigate recent declines in bumblebee populations, I carried out landscape analyses, made field studies of bumblebees, flowering plants and pollination in an agricultural region in southernmost Sweden. Studies were carried out in landscapes of contrasting agricultural intensity and land-cover configuration; "simple" landscapes highly dominated by large crop fields, and "complex" with mixed f
An undergraduate course in Strategic Management seemingly provides similar basic content to students including the infamous SWOT (strengths, weaknesses, opportunities and threat) analysis along with the identification of functional level, business level, and generic strategies to enhance an organization’s competitiveness. One of the most common resources for this type of course is the article outl
The combination of quantum mechanics and molecular mechanics (QM/MM) is one of the most promising approaches to study the structure, function, and properties of proteins. We here review our applications of QM/MM methods to alcohol dehydrogenase, blue copper proteins, iron–sulphur clusters, ferrochelatase, and myoglobin. We also describe our new quantum refinement method, which is a combination of
Alanine metabolism in the ectomycorrhizal fungus Paxillus involutus was investigated using [N-15]alanine. Short-term exposure of mycelial discs to [N-15]alanine showed that the greatest flow of N-15 was to glutamate and to aspartate. Levels of enrichment were as high as 15-20% for glutamate and 13-18% for aspartate, whereas that of alanine reached 30%. Label was also detected in the amino-N of glu
We have studied morphology and phase segregation of AlInP shells on GaAs nanowires. Photoluminescence measurements on single core- shell nanowires indicated variations in the shell composition, and phase segregation was confirmed by cross-sectional scanning transmission electron microscopy on 30 nm thin slices of the wires. It was discovered that Al-rich domains form in the á112ñ directions where
Forestry is of major economical importance in Europe, and recent devastating windstorms have pinpointed the vulnerability of this economic sector to windstorms. Forest damage is an important economic issue at a country level and may become even of larger concern under future conditions following global warming. An underlying question is to what extent the storm damage is due to changes in the wind
An NMR technique to measure exchange kinetics at thermal equilibrium in dispersions of moderately soluble crystalline material is presented. By monitoring the exchange of molecules between pools in solid and dissolved form, one can characterize the surface specific exchange rate. Illustrative experiments were performed in a model system with beta-type crystals of tripalmitin as the solid phase and
ZnWO4, ZnWO4 : Fe and ZnWO4 : Mo crystals were investigated by the methods of time-resolved spectroscopy in the temperature range of 4.2-300 K. It is shown that the Mo and Fe impurities significantly reduce the light yield of ZnWO4. The main 2.5 eV emission of ZnWO4 and the 1.77 eV emission band of ZnWO4 : Mo are shown to originate from the triplet excited state of the WO6 and MoO6 complex, respec
OBJECTIVE:: The risk factor pattern underlying a parental history of myocardial infarction (MI) is incompletely understood. We examined whether a parental history of clinically verified early MI may promote development of insulin resistance, obesity and the metabolic syndrome (MetS). METHODS:: One hundred and seventy-four offspring to patients with clinically verified MI before 60 years of age i
Using a choice blindness paradigm, it is possible to switch decisions and outcomes in simple choice tasks. Such switches have been found to carry over into later choices, hypothesized to be mediated by beliefs about earlier decisions. Here we investigated participants’ memories for stimuli in a simple choice blindness task involving preferential choices between pairs of faces. We probed participan
Abstract Aim: To describe the consumption of snuff in a rural male population and to explore associations between snuff use and obesity. Participants and Methods: Tobacco use was explored in 834 men aged 30-75 years old who participated in a cross-sectional population survey in the municipality of Vara (participation rate was 81%). Self-reported questionnaires assessed the habits of smoking and sn
