Sediments from the small lake Ilsø situated in the Illerup/Alken Enge Valley were studied in order to investigate past landscape development at the time of a probably ritual human mass burial following battle during the Roman Iron Age (ad 1–400). A pollen record from Ilsø and a number of other records from Jutland were combined using the Landscape Reconstruction Algorithm to reconstruct local vege

Bacterial plasmids are extensively involved in the rapid global spread of antibiotic resistance. We here present an assay, based on optical DNA mapping of single plasmids in nanofluidic channels, which provides detailed information about the plasmids present in a bacterial isolate. In a single experiment, we obtain the number of different plasmids in the sample, the size of each plasmid, an optica

East African landscapes today are the result of the cumulative effects of climate and land-use change over millennial timescales. In this review, we compile archaeological and palaeoenvironmental data from East Africa to document land-cover change, and environmental, subsistence and land-use transitions, over the past 6000 years. Throughout East Africa there have been a series of relatively rapid

The main focus of the work presented in this thesis is on experimental studies oflaser acceleration of protons and other positive ions from solid targets. The topic is explored from three different angles: firstly, the development of diagnostics adapted to the ion pulses, secondly, the characterization of the source of the energetic particles and, finally, the application of laser-accelerated prot

The workshop brings together differing perspectives on what makes research data possible. How data is made represents an on-going negotiation between a number of elements. It reflects, firstly, the nature of disciplines and thecomplex way this is linked to cultures of research data and data sharing. Secondly, data is made across the complex temporalities within different practices of its managemen

Western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripiclae), cause very large economic damage on a variety of field and greenhouse crops. In this study, plant resistance against thrips was introduced into transgenic potato plants through the expression of novel, custom-made, multiclomain protease inhibitors. Representative classes of inhibitors of cysteine and aspartic

In view of the rising proportion of elderly in the population, diffusion of medical technologies to the elderly is a particularly interesting phenomenon, with respect to both quality of life and health care costs. Using data on all carotid endarterectomies (CEAs) performed in Sweden, we explore the pattern of age diffusion 1982-1999. The overall rates of CEA are considerably lower in Sweden than i

The objective was to study the effects of ethanol on coagulation and fibrinolysis in whole blood. Blood samples from healthy volunteers were analyzed before and after in-vitro addition of ethanol in order to achieve ethanol concentrations of 0, 1, 2 and 4[per mille sign], respectively (0, 22, 44 and 88 mmol/l). Coagulation and fibrinolysis were then assessed using rotational thromboelastometry. We

Despite significant advances in the understanding and modelling of turbulent combustion, no general model has been proposed for simulating flames in industrial combustion devices. Recently, the increase in computational possibilities has raised the hope of directly solving the large turbulent scales using large eddy simulation (LES) and capturing the important time-dependant phenomena. However, th

Somatic mosaicism, the presence of genetically distinct cells within an organism, has been increasingly associated with human morbidity, ranging from being a cause of rare syndromes to a risk factor for common disorders such as malignancy and cardiovascular disease. Previous studies interrogating the normal prevalence of somatic mosaicism have focused on adults. We here present an estimate of the

This thesis summarizes the experimental work in which an ultrafastX-ray laser plasma source was combined with variousscalable direct detection schemes to test a novel approach forlab-based time-resolved X-ray absorption spectroscopy. A laserplasma source based on a water jet target was built and commissioned.X-ray and electron emissions of this source were characterizedwith various direct detectio

PURPOSE: Epidemiological studies suggest that low levels of vitamin D constitute a risk factor for prostate cancer. However, the results are conflicting, perhaps because prostate cancer is a very heterogeneous disease. More recent studies have focused on cancer progression and mortality. Vitamin D is closely related to both calcium metabolism and parathyroid hormone (PTH) levels, and all three fac

Forecasting volatility is a fundamental topic in in both academic and applied financial economics. Different GARCH-specifications are by far the most popular model based approach used for this purpose. This thesis evaluates the forecast accuracy of some specific GARCH-models; GARCH, EGARCH, APGARCH and MRS-GARCH. The primary purpose of the essay is to investigate whether the more flexible two-regi

This thesis asks the question “How do government-initiated local referendums affect citizens’ perceptions of democracy?”. In the theoretical discussion, direct democratic theory is found to be inadequate in studying the effects of government-initiated referendums. Since the referendums are government-initiated, that negates the important aspect of bypassing elites. The referendum democracy concept

In an uncertain future, flexibility and ability to adapt are recognized as important factors in avoiding errors, but also discover new ways of handling urban problems. This thesis examines how standardized wooden modules can be used to modify, manipulate and reinvent public space. It also investigates how flexibility in design could help to involve communities and individuals in reshaping and recy

Bakgrund: Hälsoläget och dödligheten bland schizofrena patienter är i jämförelse med normalpopulationen klart försämrad. Patientgruppen dör i genomsnitt 10-20 år tidigare och kardiovaskulära sjukdomar (CVD) är särskilt utmärkande. Patientgruppen lever stillasittande liv i högre utsträckning, men fysisk aktivitet, fysisk träning och ökad fysisk fitness har i flera studier visat sig ha goda hälsoeff

Investments in risk reduction are very complex with many factors that affect the overall profitability of the investment. Therefore, different models and approaches are used in the decision making process. An analysis of the problem is then made according to certain basic rules. When the risk situation is evaluated in this manner the decisions that are made are rational and consistent. By using th
