The influence of the factor V Leiden mutation on the development of neovascular complications in central retinal vein occlusion was studied. The presence of the mutation was found to enhance the risk of developing neovascular complications almost threefold compared to in patients without the mutation. Optic nerve head swelling, which recently has been presented as an indicator of good prognosis i
Factor H is the main fluid phase regulator of the alternative pathway of complement. Factor H acts as a co-factor for factor I-mediated C3b degradation, inhibits the formation of the C3bBb convertase and accelerates its decay. By discriminating between host and foreign cells, factor H inhibits complement-mediated injury to host cells. Factor H mutations have been associated with atypical hemolytic
The formation of the kingdom of Denmark is generally presented as a linear process linking ancient chiefs to the modern nation state of Denmark. This dissertation focuses on the small stories behind this great narrative of Denmark. The purpose is to show that there never was any formation process. Instead, encounters between people in the local landscapes and the Danish kingdom were both considera
This thesis consists of an introductory chapter and four research papers, summarized as follows. The overall purpose is to study various external effects of the transport system; effects that are not considered (or not fully considered) today. The first paper estimates the relationship between accident frequency and homogeneous and inhomogeneous traffic flows, which is useful for calculating the
The Grammar of The Hype digital information technology -IT- in retelling as myth its experienced reality and in scientific analysis or the IT-hype in the years prior to and at the turn of the millennium waiting for the next hype and the next, and“next”... This is the title of my thesis and it focuses rather on a particular “hype” than deals with the so-called information society as such. What is
The main purpose of this thesis is to examine the impact of social change on Chinese intergenerational relations in contemporary Singapore. Within only three decades, Singapore has turned into a wealthy and sophisticated metropolis with a highly educated labor force. The massive transformation, however, has been accompanied by the emergence of a deep and complex generation gap. Apart from the leap
Uncontrolled proliferation and invasion are two characteristics in tumour development and progression. Previous studies have shown that invading tumour cells in colorectal cancer have low proliferation in parallel to upregulation of the tumour suppressor p16. We set out to detail the p16 expression and proliferation in basal cell carcinoma and squamous cell carcinoma of the skin, tumours that are
For the sacrifice shelamim in the Hebrew Bible, scholars have suggested a number of different interpretations and uses. This sacrifice also had an ambiguous role in Israelite culture. Lack of a general consensus and the failure to reach a satisfying solution makes the shelamim a puzzle and an interesting sacrifice to investigate with insights gained from modern ritual studies. In this study, it i
The number of fractures is increasing worldwide, and fractures frequently cause long-term disability, impaired quality of life and sometimes death. The Malmö Preventive Project, a population-based, prospective study, consisting of 22 444 men, mean age 44 and 10 902 women, mean age 50 years, provides data for evaluation of common public health conditions, such as fracture and diabetes. The follow-u
In this Thesis, I studied some of the current aspects of organic matter photochemistry. I analyzed abiotic phototransformations of several types of dissolved (DOM) and particulate organic matter (POM). I also evaluated the effects of phototransformation of several types of DOM on bacteria. Finally, in a field experiment, I analyzed net effects of solar radiation on organic matter decomposition. DO
This study gives an account of a teaching situation in the eighth grade with 20 student's aged 14-15. The students have worked with a scientific problem focussed on the greenhouse effect and the earth's global warming, based on a problem solving and information seeking way of working in groups. Their task has been to describe the phenomena and factors that influence the earth's global temperature
This thesis focuses on two problems in the field of computer vision and image analysis. The first part of the thesis deals with image localization. The goal is simply to answer the question: Where was this picture taken? To answer this two things are needed: A model of the world, or at least the relevant parts of the world, and a method for relating a new image to the model. The thesis presents ne
The development of a miniaturised silicon wafer integrated enzyme reactor is described. The reactor was micromachined by anisotropic wet etching of (110) silicon. The enzyme glucose oxidase (GOx) was coupled to the reactor surface with standard methods of immobilising enzyme to silica. The glucose turn-over rate was monitored following a colourimetric assay. The advantage, in terms of high surface
Abstract: This thesis consists of four papers related to various aspects of water waves with vorticity. Paper I: Symmetry of steady periodic gravity water waves with vorticity. We prove that steady periodic two-dimensional rotational gravity water waves with a monotone surface profile between troughs and crests have to be symmetric about the crest, irrespective of the vorticity distribution wi
This thesis presents contributions to structure-and-motion estimation, a central topic in the field of geometric computer vision. In particular, the problem of view planning is considered, and continuous and discrete optimization-based algorithms are given for how to plan the path of a sensor to its destination, while balancing the competing goals of path length and reconstruction accuracy. The sa
Nowadays, more than 90% of our energy comes from combustion processes. Hence, it is very important to perform combustion research to reduce emissions, improve efficiency, find clean and renewable fuels, strengthen safety, etc. The complexity of combustion processes asks for advanced diagnostic tools, among which the laser spectroscopy has been proved to be a powerful one. This thesis is about the
Simulation of coupled dynamical systems, where the subsystems are bundled with their own internal solver, is important in industry. This is due to that in many cases, with complex systems, this is the only viable option. In this setting, the dynamics of each system is hidden and information between subsystems is exchanged through sampled inputs and outputs, a weakly coupled system. While a new ind
The results presented in this thesis can be divided into four areas of investigation: Investigation of the effect of new volume-crank angle relations on engine emissions, power and efficiency; investigation of nitrogen oxides effect on auto ignition and knock in SI engines; investigation of premixed SI and HCCI engine operation with the alternative fuels hydrogen and reformed methanol gas (RMG); s
Deprived of human rights, more than half of all people with disabilities in developing countries live in extreme poverty. Although considered a prerequisite for equalization of opportunities, about nine out of ten of those who need assistive technologies do not have access to them. Little is known about the socioeconomic benefits of using assistive technology in low-income countries that can infor
The neurotrophins, notably brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3), modulate synaptic transmission and synaptic plasticity in the adult mammalian brain. Recent data suggest that neurotrophins might be mediators of activity-dependent synaptic plasticity. Such plasticity is believed to be a cellular correlate for important processes like learning, but also for diseases, for
