This article is based on a study of the sailing event America’s Cup in Malmö in the late summer of 2005. It serves the purpose of exemplifying a project of urban governance. Urban governance means that municipalities are engaged in implementing different strategies in order to strengthen their own position in the competition between cities and regions. The article’s main theme is the relation betw
Popular Abstract in English For several decades the electronic industry has developed towards smaller and smaller electronic components. The idea behind this development is quite simple: Small components have faster response times, which enables faster devices. Also, smaller components make it possible to decrease the size of the devices. A common example is today's mobile phones, that actually arThis dissertation deals with the effects of coherence and correlations on transport through nanostructures. Simulations are mainly performed using the second order von Neumann approach, a method capable of dealing with these effects in the presence of higher order tunneling. We see that such effects can result in various kinds of current suppression as well as efficient thermoelectric devices. Fu
A previous study has shown that serum levels of the active vitamin D metabolite 1,25-(OH)2-vitamin D were inversely related to blood pressure levels while the prohormone 25-OH-vitamin D was found to be related to insulin metabolism. Also other clinical and experimental data support the view that vitamin D metabolism is involved in blood pressure regulation and other metabolic processes. The presen
Background: Weused a sensitive and specific beta-site amyloid precursor protein (APP)-cleaving enzyme 1 (BACE1) assay to determine the relationship between BACE1 activity in cerebrospinal fluid (CSF) and markers of APP metabolism and axonal degeneration in early and late stages of Alzheimer disease (AD). Objective: To assess CSF BACE1 activity in AD. Design: Case-control and longitudinal follow-up
Background. Flecainide is a first-line rhythm control treatment for patients with atrial fibrillation (AF), however long-term treatment outcomes are understudied. Objective. To investigate associations of electro- (ECG) and echocardiographic indices with safety and efficacy outcomes of long-term flecainide treatment for recurrent AF. Methods. Consecutive patients with AF admitted for in-hospital f
About 4.4% of the global emissions of greenhouse gases can be ascribed to healthcare. Intensive care is among the most resource intensive specialties and the purpose of this study was to quantify the total climate impact of a Swedish intensive care unit (ICU) and identify modifiable elements that can lower the intensive care unit’s climate impact. A process-based life cycle assessment was conducte
Organising knowledge in a corporate environment : a case study at the development departments of Ecophon AB The purpose of this master's thesis is to investigate how three development departments of a technical firm could organise their collection of documents and information resources to improve their management of information. Three sets of questions have been posed: 1) How does the target
Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusi
Sri Lanka has been a leading example among developing nations in the fight against poverty. Human development has been a priority of the Sri Lankan government, and many social indicators are today more in line with those of a developed country. Still poverty is a severe and widespread problem in the country. The economic growth has been under the country’s potential, and the unequal development ha
Background: Many pathological processes can disrupt the integrity of the glomerular capillary wall and cause a massive leakage of protein, resulting in nephrotic syndrome (NS). Clinical parameters such as age, sex, renal function, presence of diabetes, and how NS is defined influence the spectrum of underlying diseases. In this study, we examine how these parameters interact.Methods: Age, sex, hem
The effects of fuel properties on the performance and emissions of an engine running in partially premixed combustion mode were investigated using nine test fuels developed in the gasoline boiling point range. The fuels covered a broad range of ignition quality and fuel chemistry.The fuels were characterized by performing a load sweep between 1 and 12 bar gross IMEP at 1000 and 1300 rpm. A heavy d
The impact of sample crushing on the detected porosity of hardened cement pastes by low temperature calorimetry (LTC) was studied using powder and cylinder samples. Two types of cements, CEM I and CEM III were used to prepare the pastes. A model porous material, MCM-41, was also used in order to investigate some aspects of the measurement and the evaluation approach. The powder and cylinder sample
We present the first in vivo application of the filter-exchange imaging protocol for diffusion MRI. The protocol allows noninvasive mapping of the rate of water exchange between microenvironments with different self-diffusivities, such as the intracellular and extracellular spaces in tissue. Since diffusional water exchange across the cell membrane is a fundamental process in human physiology and
Aims and objectives: The research presented investigates older people’s expectations of social assistive robots and telehealthcare systems. Methods: The empirical studies presented are based on fieldwork carried out before social assistive robots and a telehealthcare system were introduced into the domestic environment of older people. The research draws upon participatory design to explore older
Popular Abstract in English Small Devices to Study Small Biology Biological components that are smaller than a cell are difficult to study directly. A great deal of work has been done developing devices and techniques that allow scientists to control and observe sub-cellular biology. In this thesis I, along with my colleagues, have made a number of devices that give us control over the small bioloSub-cellular biological components are complex systems that work together to control and maintain cellular activity and health. It is useful to study the basic elements that constitute the sub-cellular components using model systems, which mimic certain parts of the overall system, in order to better understand the system as a whole. Here we present a number of tools, which enable the study of a f
OBJECTIVES: The aim of this study was twofold: (i) to evaluate the air levels of N-nitrosamines in the Swedish rubber industry and (ii) to estimate the risk of symptoms and changed levels of immunologic markers in relation to these levels.METHODS: Using adsorption tubes, we collected samples of N-nitrosamines in the breathing zone of 96 rubber workers and analyzed them with liquid chromatography t
During the stress response adrenal medullary chromaffin cells release catecholamines to the bloodstream. Voltage-activated calcium channels present in the cell membrane play a crucial role in this process. Although the electrophysiological and pharmacological properties of chromaffin cell calcium channels have been studied in detail, the molecular composition of these channels has not been defined
Objective: To investigate how subjective perceptions of everyday occupations, activity level, day centre attendance, social interaction, self-mastery and clinical factors were related to how unemployed people with psychiatric disabilities (PD) envision a future worker role, also controlling for socio-demographic variables. Participants: 175 people with PD; 93 attended a day centre and 82 did not.
This study focused on older patients participating in a team meeting (TM) in a hospital ward in Sweden. A process had taken place on the ward, in which the traditional round had developed into a TM and understanding what participating in a TM means for the older patient is necessary for the development of care that facilitates older patient's participation. The aim of this study was to describe th
Invasive species often have instable population dynamics and are known to collapse or oscillate heavily after passing through the initial lag/growth phases. Long-term data-series documenting these fluctuations are however rare. We use long-term (starting in the early 1960s), semi-quantitative data on the invasive signal crayfish (Pacifastacus leniusculus), capturing its population development afte
