Purpose: Reduced rapid-eye movement (REM) sleep has been linked to increased mortality in the general population. We investigated whether diminished REM sleep is associated with higher mortality in adults with coronary artery disease (CAD) and obstructive sleep apnea (OSA). Methods: This secondary analysis of the RICCADSA trial included 356 revascularized CAD patients with OSA (apnea–hypopnea inde

Background: Helicobacter pylori (Hp) and its virulence factor Cytotoxin-associated gene A (CagA) have been linked to myocardial infarction (MI), but the mechanisms are unknown. This study aims to test if Hp infection and CagA are associated with pre-specified inflammatory and vascular biomarkers in patients with MI and to explore whether a broader biomarker panel can predict infection. Furthermore

Background: The life expectancy of pancreatic cancer patients remains minimal. The disease progression may be influenced by type 2 diabetes (T2D) and inflammatory status, although important gaps persist around their joint effects on disease outcome. The aim of this study was to investigate the clinical significance of the tumour immune microenvironment on pancreatic cancer prognosis in relation to

The purpose of this master’s thesis is to provide a contribution to the research body regarding consumer returns, particularly within the online fashion retail industry. A quantitative data analysis approach is chosen and two main methods are used: data study that aims to identify patterns and interesting relationships in the data, and a simulation study that uses real input data to attempt to ide

Asset prices have had larger and more rapid increases since 1980 when compared to the post-war period, especially compared to the Bretton Woods period. In this thesis we test whether the excess elasticity view provides a plausible explanation for this change. The excess elasticity view, put forth by Borio and Disyatat (2011) and Borio and White (2003), argues that the financial system has become m

Purpose: The aim of this paper is to find out how the PMM system can be used to remain resilient to a change in the environment and so continue to provide appropriate guidance to managers in real time. Methodology: The paper is based on a qualitative research method with primarily an abductive approach to derive insight about a PMM system’s use to remain resilient to a change in the environment.

Title: CEO Narcissism, Divestitures, and Shareholder Value: A Study on the Nordic Market Seminar date: 2019-06-03 Course: BUSN79, Degree project in Accounting & Finance, Graduate level, 15 ECTS-credits Authors: Alan Alfat, Christian Erlandsson Advisor: Håkan Jankensgård Keywords: Narcissism, Divestitures, event-study, CAR, BHAR Purpose: This study aims to investigate whether CEO Narcissi

Personlighetsforskare är oense om huruvida personlighet och kompetens är åtskilda. Tidigare forskning har visat att det finns en skillnad i personlighetstester mellan items som relaterar till hur folk tenderar att bete sig från hur väl personer utför beteenden, d.v.s. kompetens (Bäckström et al., 2020). Vi undersökte hur mängden kompetensrelaterad information vid beskrivning av människors egenskapThere is disagreement in the personality research-field whether competence and personality should be separate concepts. Bäckström et al. (2020) showed that people could separate items relating to frequency of behavior (personality) from items relating to quality of behavior (competence). We looked at how the amount of competence-related information, when describing people's characteristics, af

This thesis is done in cooperation with Dresser Wayne AB in Malmö and the objective has been to investigate if it is possible to use the X-flo meter, see Figure 1, in an LPG-dispencer. An increased pressure is used in the LPG-system, which involves a higher risk of leaking and strength problems. During the development consideration has been taken to a new outlet, though other couplings are used in

This thesis project was to develop a module for a forest precision seeder. The project is made at BCC AB. BCC is a worldwide supplier of forest seed centre and containerized nursery equipment. BCC develops, designs, produces and sales machines for forest seed handling. BCC s existing precision seeder can not handle seed that are tinier than 1 mm in diameter. With a growing market in countries with

Kolloider är partiklar i storleksordningen nm till μm. De är viktiga i biologiska system, där exempelvis proteiner är en typ av kolloid. Att studera kolloider ger oss därför insikt i hur till exempel proteiner byggs upp och interagerar. I detta fall försökte vi tillverka kolloidala molekyler, alltså kolloider som interagerar med varandra genom ett specifikt antal bindningar i väl definierade positThe ability of thermoresponsive, amine-functionalized microgel particles to take part in microgelmicrogel inter-cross-linking has previously been reported in the literature, in connection to applications such as for example the formation of stimuli-responsive colloidal gels and colloidosomes [1]. This thesis deals with the synthesis of such thermoresponsive, cross-linkable microgels and their subs

Introduction: This study evaluated lipid identification using mass spectrometry. Background: Three main modes of acquisition are used in mass spectrometry of lipids; data-independent acquisition (DIA), data-dependent acquisition (DDA) and targeted acquisition. DIA is the most including one, yielding a complete but complex data set, while targeted is the least including one, basing acquisition on

Generally credited to have originated in 2005, coworking spaces provide hybrid work environments to individual professionals, entrepreneurs, and start-ups. Simultaneously, social entrepreneurship has received increasing attention as a solution to topical problems. This thesis aims to provide an empirical exploration of the ways in which coworking spaces facilitate social entrepreneurship, seen fro

Background: Recent reviews conclude an association between traffic-related pollution and incidence of asthma in children, but not all studies agree. Studies have almost exclusively relied on parental-reported symptoms or parental-reported diagnoses of asthma and wheeze. Our aim was to investigate if traffic exposure is associated with higher incidence of early onset asthma, using registry-based ou

Background: The objective was to investigate in a group of obese subjects the course in skeletal muscle phospholipid (SMPL) fatty acids (FA) during a 24-weeks weight maintenance program, which was preceded by a successful very low calorie dietary intervention (VLCD). Special focus was addressed to SMPL omega-3 FA, which is a lipid entity that influences insulin action. Methods: Nine obese subjects

We report on the multi-wavelength observations of PKS 1510-089 (a flat spectrum radio quasar (FSRQ) at z = 0.361) during its high activity period between 2008 September and 2009 June. During this 11 month period, the source was characterized by a complex variability at optical, UV, and gamma-ray bands, on timescales down to 6-12 hr. The brightest gamma-ray isotropic luminosity, recorded on 2009 Ma

Background and purpose - Treatment of Dupuytren's contracture (DC) with collagenase Clostridium histolyticum (CCH) consists of injection followed by finger manipulation. We used a modified method, injecting a higher dose than recommended on the label into several parts of the cord, which allows treatment of multiple joint contractures in 1 session and may increase efficacy. We studied the occurren
