Uppsatsens syfte är att undersöka vilka motiv för börsintroduktion som angavs av de svenska bolag som noterades på Stockholmsbörsen 1997 och att undersöka huruvida bolagens ledning anser att målen med de angivna motiven har motsvarat förväntningarna, samt att undersöka vilka andra eventuella effekter börsintroduktionen har medfört. Vi har som helhet genomfört en kvalitativ studie. Vår undersökning
Objectives: To develop an automated tool for the analysis of electrocardiograms (ECG) with respect to changes that make the patient a candidate for reperfusion therapy. An additional aim was to assess the influence of the tool on the ECG classifications of three interns. Methods and Results: An artificial neural network was trained to interpret ECGs regarding changes making the patient a candi

Abstract in UndeterminedVery large MIMO is a technique that potentially can offer large network capacities in multi-user scenarios where the users are equipped only with single antennas. In this paper we are investigating channel properties for a realistic, though somewhat extreme, outdoor base station scenario using a large array. We present measurement results using a 128 element linear array ba
Time is a fundamental aspect of human cognition and action. All languages have developed rich means to express various facets of time, such as bare time spans, their position on the time line, or their duration. The articles in this volume give an overview of what we know about the neural and cognitive representations of time that speakers can draw on in language. Starting with an overview of the
We present an interactive, searchable expressed sequence tag database for the periwinkle snail Littorina saxatilis, an upcoming model species in evolutionary biology. The database is the result of a hybrid assembly between Sanger and 454 sequences, 1290 and 147 491 sequences respectively. Normalized and non-normalized cDNA was obtained from different ecotypes of L. saxatilis collected in the UK an
The aim of the present work is to introduce an innovative framework for employing 3D-GIS as an exploratory platform to perform visual analysis. Such a methodology is aimed at detecting patterns of visibility to simulate the past human perception of specific categories of artifacts placed inside a virtually reconstructed three-dimensional space. As a case study, the house of Caecilius Iucundus in P
Background and Aims: In a retrospective study using stereotactic body radiotherapy (SBRT) in medically inoperable patients with stage I NSCLC we previously reported a local control rate of 88% utilizing a median dose of 15 Gy x 3. This report records the toxicity encountered in a prospective phase II trial, and its relation to coexisting chronic obstructive pulmonary disease (COPD) and cardiovascu
BACKGROUND: Infections caused by Chlamydia pneumoniae are considered to participate in inflammatory processes leading to coronary artery disease. After a primary infection, the bacteria remain dormant intracellularly causing a chronic inflammatory stimulus. MATERIALS AND METHODS: Blood samples were obtained from 235 patients with acute myocardial infarction (AMI) and 108 patients with unstable ang
We report a population based case-control study of exposure to pesticides as risk factor for non-Hodgkin lymphoma (NHL). Male and female subjects aged 18-74 years living in Sweden were included during December 1, 1999, to April 30, 2002. Controls were selected from the national population registry. Exposure to different agents was assessed by questionnaire. In total 910 (91 %) cases and 1016 (92%)
The purpose of this study was to examine the relation between poor sleep and nonsuicidal self-injury (NSSI), and to test the hypothesis that poor sleep is a risk factor for the development of NSSI in young adolescents. Questionnaire data were used from a 2-wave longitudinal study of a community sample of 881 young Swedish adolescents. The results showed that 7 % of the girls reported poor sleep (n
OBJECTIVE: To determine which factors increase the risk of large caesarean scar defects as assessed by transvaginal ultrasound. DESIGN: Observational cross-sectional study. SETTING: University Hospital. POPULATION: One hundred and eight women who had undergone one caesarean section. METHODS: Transvaginal ultrasound examination of the scar in the uterus 6-9 months after the caesarean. Published ult
Flame flashback from the combustion chamber to the premixing section is a major operability issue when using high H-2 content fuels in lean premixed combustors. Depending on the flow-field in the combustor, flashback can be triggered by different mechanisms. In this work, three flashback mechanisms of H-2/CH4 mixtures were visualized in an atmospheric variable-swirl burner using high speed OH* che
BACKGROUND: Multifocal electroretinogram (mfERG) has the power to discriminate between localized functional losses and overall retinal changes when evaluating retinal injury. So far, full-field ERG has been the gold standard for examining retinal ischemia and the effects of different neuroprotectants in experimental conditions. The aim of the present study was to establish mfERG, with simultaneous
Fuel cells, redox flow batteries and some water desalination technologies such as reverse osmosis and electrodialysis require efficient ion exchange membranes to perform in an optimum way. Thus, by enhancing the properties of these membranes there is a possibility to improve this type of applications and technologies. Depending on the specific application, anion or proton exchange membranes with g
Power consumption is an important design parameter for battery operated devices, and an especially sensitive issue in embedded Java systems. This paper presents a solution to reduce leakage power consumption of the heap memory characteristic of Java processors. By partitioning the heap into several memory banks and taking advantage of a compacting garbage collector, our method dynamically powers o
