Sites and the mental landscape : Stone Age in the Kullen district, North-western Scania, Sweden

Abstract in Undetermined The approach of the mental landscape enlarges the perspectives for interpreting sites and settle- ments. In the Kullen district sites and settlements is theorized by breaking down the dichotomi- es of Mesolithic and Neolithic and the archaeologically constructed borderline between the periods. The terminology and the interpretation of site and settlement need to be extende

How to promote renewable energy systems successfully and effectively

This paper summarises the major recommendations and conclusions of the third Forum of the European Network on Energy Research (ENER) which took place in June 2002 in Budapest. The major perceptions of this meeting as well as the most important conclusions and recommendations for energy policy makers are compiled in this summary. The statements compiled in the following represent a consensus within

Understanding Zircon Geochronology - Constraints from Imaging and Trace Elements

Formation of incipient charnockite in Söndrum, SW Sweden and the Kerala Khondalite Belt (KKB), S. India is accompanied by zircon growth. The age of the dehydration event is constrained by dating newly formed zircon to 1397±4 Ma (2?, MSWD=1.7) in Söndrum and ca. 520-510 Ma in S. India by secondary ionization mass spectrometry (SIMS). The formation of incipient charnockites correlates with regional

A measurement of the tau hadronic branching ratios

The exclusive and semi-exclusive branching ratios of the tau lepton hadronic decay modes (h(-)upsilon(tau), h(-)pi(0)upsilon(tau), h(-)pi(0)pi(0)upsilon(tau), h(-) >= 2 pi(0)nu(tau), 2h(-)h(+)upsilon(tau), 2h(-)h(+)>= 2 pi(0)upsilon(tau), 3h(-)2h(+)upsilon(tau) and 3h(-)2h(+) >= 1 pi(0)upsilon(tau)) were measured with data from the DELPHI detector at LEP.

Neuronal plasticity and dendritic spines: effect of environmental enrichment on intact and postischemic rat brain.

The authors compared the influence of environmental enrichment on intact and lesioned brain, and tested the hypothesis that postischemic exposure to an enriched environment can alter dendritic spine density in pyramidal neurons contralateral to a cortical infarct. The middle cerebral artery was occluded distal to the striatal branches in spontaneously hypertensive rats postoperatively housed eithe

Intracapsular pressure and loosening of hip prostheses. Preoperative measurements in 18 hips

We measured the intracapsular pressure preoperatively in 18 hips (17 patients) before revision of a total hip arthroplasty because of aseptic loosening. Distension of the joint capsule was measured with sonography in 13 cases. In extension, the mean intracapsular pressure was 26 (0-60) mmHg, in extension and inward rotation it was 159 (24-280) mmHg, in extension and outward rotation it was 30 (3-6

The impact of stent design on proximal stent-graft fixation in the abdominal aorta: an experimental study

OBJECTIVE: to study the proximal fixation of different aortic stent grafts in comparison to a hand-sewn anastomosis. DESIGN: experimental study. MATERIAL: the infrarenal aorta of 16 human cadavers were exposed, left in situ and transected 3 cm above the aortic bifurcation to mimic an infrarenal aortic neck. Stent grafts were deployed through a sheath 5 cm into the aorta. Ancure, Talent, Vanguard,

Impact of natural and artificial UVB radiation on motility and growth rate of marine dinoflagellates

The growth rates and motility of dinoflagellates were studied in the field in the presence or absence of UVB radiation, as well as in the laboratory under artificial radiation conditions. Photosynthetically active radiation (PAR, 400–700 nm) and UVB radiation showed large variations due to cloud cover and seasonal changes in natural daylight. In Swedish coastal water, UVB radiation was attenuated

Overweight, obesity and fat distribution in 50-to 64-year-old participants in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Objective: To describe anthropometric characteristics of participants of the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: A cross-sectional analysis of baseline data of a European prospective cohort study. Subjects: This analysis includes study populations from 25 centres in nine European countries. The British populations comprised both a population-based and a 'he

Föreställd hedendom. Tidigmedeltida skandinaviska kyrkportar i forskning och historia

Popular Abstract in Swedish Avhandlingen diskuterar tidigmedeltida skandinavisk konst, främst kyrkdörrar och portaler från Sverige och Norge. Kyrkans ingång är särskilt lämplig att studera dels eftersom den markerade en gräns för det heliga rummet, dels därför att den var en viktig mötesplats i lokalsamhällena. Genom kontextualiseringar och kritisk forskningshistorik skapas en delvis ny bild av deThe thesis discusses Medieval Scandinavian art, in particular church doors and portals from 12th and 13th century Sweden and Norway. The entrance of the church was a demarcation of holiness, but also a meeting place for the local communities, where otherwise secular activities could be legitimatized by the ecclesiastical context. This makes the doors and portals of special interest for the study o

Administrative Reforms and the Quest for Foreign Investment in China : The Case of Shenzhen

This study examines the attempts made by one local government in China, Shenzhen, to improve its investment environment for foreign-invested enterprises through administrative reforms between 1980 and 1997. Three empirical questions are posed: what reforms have been undertaken, what effects have they had and how have changes in the organizational environment affected them. The theoretical aim is

Dercum's disease. Fatty tissue rheumatism caused by immune defense reaction?

Dercums sjukdom, adiposis dolorosa eller, mera allmänt, fettvävsreumatism är en relativt okänd sjukdom trots att den beskrevs redan 1888 av den amerikanske neurologen Francis Xavier Dercum. Den drabbar företrädesvis 20–40-åriga kvinnor, men kan även debutera hos barn. Kännetecknande är en uttalad smärta i fettväven. Patienterna har liksom fibromyalgikerna ofta nonchalant avfärdats med att »alla fe

Television in Time: Research Images and Empirical Findings

The thesis contains a general theoretical and historical argument and the application of this argument to specific empirical data gathered over a period of 23 years among young people in Iceland. The first part consists of a selective review of the international research literature on television at the time of writing. This review leads to the establishment of three stages in the development of t

High-density haplotype structure and association testing of the insulin-degrading enzyme (IDE) gene with type 2 diabetes in 4,206 people

The insulin-degrading enzyme is responsible for the intracellular proteolysis of insulin. Its gene IDE is located on chromosome 10, in an area with suggestive linkage to type 2 diabetes and related phenotypes. Due to the impact of genetic variants of this gene in rodents and the function of its protein product, it has been proposed as a candidate gene for type 2 diabetes. Various groups have explo

The influence of multiple introduced predators on a littoral pond community

In a replicated field experiment we studied the effects of natural densities of two exotic consumers, the predatory and herbivorous signal crayfish (Pacifastacus leniusculus) and the predatory rainbow trout (Oncorhynchus mykiss), on multiple trophic levels of a pond community. The goals were to: (1) determine the individual and combined effects of predators on macroinvertebrates, macrophytes, and

Effects of ultrasound contrast agents on Doppler tissue velocity estimation

The combination of Doppler tissue imaging and myocardial contrast echocardiography has the potential to provide information about motion and perfusion of the myocardium in a single examination. The purpose of this study was to establish how the presence of ultrasound contrast agent (UCA) affects measurements of Doppler tissue velocities in vivo and in vitro. We performed echocardiography in 12 pat
