The main objective of this thesis was to quantitatively estimate the gaseous exchange of carbon dioxide (CO2) and methane (CH4) between a subarctic wetland ecosystem and the atmosphere. Additionally some initial estimates of the carbon input to the atmosphere of nonmethane hydrocarbons (NMHCs) were also obtained by combining different techniques in a joint setting. The data presented were collecte
Background: Thrombolysis is a common method in the treatment of lower extremity bypass graft occlusion. The purpose of this study was to investigate the results of thrombolytic therapy in the management of acute bypass graft occlusion and to identify risk factors for technical failure and amputation. Methods: All patients at two tertiary referral centers undergoing thrombolysis for acute graft occ
Popular Abstract in Swedish Hemofili A är en form av blödarsjuka som beror på en medfödd defekt av äggviteämnet faktor VIII (FVIII). FVIII spelar en viktig roll för att kroppens blodlevringsförmåga (s.k. koagulation) ska fungera optimalt och med nedsatt funktion hos FVIII riskerar man att drabbas av allvarliga blödningar i framför allt leder, men även i muskler, slemhinnor (t.ex. näsblödning) och
Popular Abstract in English Energy savings and climate change mitigation have been discussed in the world since the oil crisis in the 1970s and the building sector has been seen as one of the largest contributors to global warming effects in the world. Energy efficiency in buildings is a critical issue to be addressed in order to reduce electricity energy used in buildings and is one of the main tMozambique, situated in south-east Africa, has sub-tropical and tropical climate and plenty of natural resources for energy production. The country is however poor, and only about 25% of the population has access to electricity from the grid. A very large part of the energy used in the country is used in the residential sector, and there is a general lack of knowledge, regulations and tools concer
Popular Abstract in Swedish Bröstcancer är den vanligaste dödsorsaken bland cancersjuka kvinnor. Därför rekommenderas regelbundna mammografiska hälsokontroller för tidig diagnostik och snar behandling för att förbättra prognosen. I Sverige rekommenderas kontroller för kvinnor mellan 40-74 år. Mammografiska hälsokontroller medför dock även risker, såsom till exempel behov av kompletterande bröstundOne side-effect of breast cancer (BC) screening is a false-positive mammogram among healthy women. That is, finding(s) on a screening mammogram that lead to additional breast examinations but where the woman is eventually considered free from BC. There is evidence of short-term psychosocial consequences of false-positive BC screening. Regarding long-term consequences, research findings are inconsi
Cross-sectional studies have associated obesity and other components of the so-called metabolic syndrome with low-grade inflammation. The temporal and causal relations of this association have not been fully explored. This study explored whether elevated levels of inflammation-sensitive plasma proteins (ISPs) (fibrinogen, orosomucoid, {alpha}1-antitrypsin, haptoglobin, and ceruloplasmin) are assoc
Popular Abstract in Swedish Denna avhandling består av tre olika uppsatser. Den första uppsatsen, Technical Efficiency and Ownership: The Case of Booking Centres on the Swedish Taxi Market” behandlar problemet med konkurrens på lika villkor. Upprinnelsen till uppsatsen var diskussioner mellan privata och offentliga aktörer på den svenska taximarknaden. De privata aktörerna hävdade att de offentligThis thesis consists of three different essays, all of which have arisen from a practical problem. In the first essay, “Technical efficiency and ownership: The case of booking centers in the Swedish Taxi Market” the purpose is to examine the question of competition on an equal basis between privately and publicly owned booking centers in the Swedish taxi market. One way to answer this question is
Vehicle design is characterized by a high number of compromises. The special role of human factors in the process is to ensure that the compromises do not occur at the expense of the driver and passengers. Within the automotive industry there is a need for the development of inexpensive and efficient ergonomic tools, facilitating a fast and cost effective car development process as well as discuss
A Warehouse Management System (WMS) is a software that tracks and manages warehouse activities. The first WMS was introduced in 1975 and today the WMS market is valued at over USD 3 billion. Most warehouses use one as quality assurance becomes unlikely plausible without software support. This thesis focuses on Company X, who are the third-largest manufacturer by revenue in their industry and a
Kemira Kemia AB produces a water treatment chemical named ”PIX-Sulfate”, where “PI” stands for “poly iron x”, and the “x” represents a conjugate ion, such as chloride or sulfate, in this case, sulfate. The main process for producing PIX Sulfate at Kemira’s plants today is to dissolve magnetite in diluted sulfuric acid and to oxidize the resulting liquid using oxygen. Currently, this process is car
Nowadays, is becoming increasingly frequent holding events in outdoor environments, involving a large number of people, even though these spaces were not designed from a safe prospective, in the way that safety is defined today. In such events, high density conditions is an ongoing issue, as the evacuation becomes very complex, due to the space design and the interaction among the pedestrians. It
Introduction: Idiopathic normal pressure hydrocephalus (iNPH) is a treatable but largely underdiagnosed neurological condition affecting the elderly population. It is characterised by gait and cognitive impairment, as well as urinary incontinence. For the most part, it is diagnosed via imaging and clinical assessments. Abnormalities in cerebrospinal (CSF) flow in the cerebral aqueduct have been li
Blood biomarkers have the potential to revolutionize Alzheimer's disease diagnosis, offering advantages over CSF and PET due to their accessibility, scalability and cost-effectiveness. This study evaluated the effectiveness of individual plasma biomarkers, such as phosphorylated Tau (pTau) 217, as well as biomarker combinations, with a focus on the pTau 217/β-Amyloid (Aβ) 1–42 ratio to predict amy
This thesis deals with the international rules regarding passenger liability on an international aircraft. The focus will be the carrier's liability toward passengers on an aircraft. The purpose is to give an account of the common international rules and to clarify the problems with interpretation of the passenger liability article. I will focus on the Montreal Convention of 1999, which is the
The principal rule of the common market is that goods and services are able to move freely across the borders of Member States. State monopolies in control of supply and demand are, therefore, only under exceptional circumstances compatible with the conditions of the common market. The compatibility of Swedish State monopolies with EC law is a controversial matter. The case-law of the ECJ lets us
Purpose: To determine progression factors at the end of the Early Manifest Glaucoma Trial (EMGT) based on all EMGT patients and evaluate separately patients with higher and lower baseline intraocular pressure (IOP; median split). Design: Cohort of clinical trial participants. Participants: Patients with early open-angle glaucoma randomized to argon laser trabeculoplasty plus betaxolol (n = 129) or
