BACKGROUND: In order to determine myocardial salvage, accurate quantification of myocardium at risk (MaR) is necessary. We present a validated novel automatic segmentation algorithm for quantification of MaR by myocardial perfusion SPECT (MPS) in patients with acute coronary occlusion. METHODS AND RESULTS: Twenty-nine patients with coronary occlusion were injected with a perfusion tracer before re
The etiology of abdominal aortic aneurysm (AAA) includes inflammation and endothelial dysfunction. To evaluate relations between these mechanisms and AAA growth, endothelin (ET)-1, tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and CD40 ligand were related to yearly AAA growth for 2.9 +/- 1.6 years (mean +/- SD) in 178 patients with conservatively followed AAA. Total number of follow-up ye
Attention is drawn to the feasibility of using high sensitivity isothermal heat conduction calorimetry to study metabolic responses of differently processed and stored fresh-cut fruit. The heat production of endogenous (tissue metabolism during 12 h of analysis at 10 degrees C for kiwifruit and strawberry) and exogenous (microbial growth during 18 d of analysis at 10 degrees C for cantaloupe) biol
The effects induced by the deposition of Li on 1 and 0 ML graphene grown on SiC(0001) and after subsequent heating were investigated using low-energy electron microscopy (LEEM) and x-ray photo-emission electron microscopy (XPEEM). For 1 ML samples, the collected photoelectron angular distribution patterns showed the presence of single pi-cones at the six equivalent K-points in the Brillouin zone b
Fractions rich in indigestible carbohydrates, such as fructan and arabinoxylan, are obtained as by-products when ethanol, starch, and gluten are produced from wheat flour. Today, these fractions are used as animal feed. However, these components may have positive physiological effects in humans. In this study, the content of indigestible carbohydrates in distillers' grains and process streams from
Using constant-effort catch data, causes of annual variation in the timing of migration of Curlew Sandpipers (Calidris ferruginea) migrating through Ottenby, Sweden, as well as the trend in timing of migration from 1946-2005, was investigated. Variation in the timing of autumn migration of adult and juvenile Curlew Sandpipers was influenced by breeding success connected to predation pressure on th
Myoglobin has the ability to react with hydrogen peroxide, generating high-valent complexes similar to peroxidases (compounds I and II), and in the presence of excess hydrogen peroxide a third intermediate, compound III, with an oxymyoglobin-type structure is generated from compound II. The compound III is, however, easily one-electron reduced to peroxymyoglobin by synchrotron radiation during cry
The use of Reinforcement Learning (RL) to design controllers for safety critical systems is an important research area. On the one hand, RL can function in and adapt to complex and changing environments without requiring a model of the system. On the other hand, in such systems robustness is of high importance, as well as ways to guarantee and certify a level of robustness. This project investigat
The purpose of this study is to investigate how femvertising, in specific advertising which aims to encourage female empowerment, is perceived by two generations of women and if it affects their attitudes toward an ad. The study is a replication of the previous study Advertising “like a girl”: Toward a better understanding of “femvertising” and its effects presented by Åkestam, Rosengren and Dahlé
Abstract The breeding season of the natterjack toad (Bufo calamita Laurenti 1768), a „prolonged breeder“, lasts up to three months in southern Sweden. However, not all reproducing individuals are present at the breeding sites during the full time span. Thus, some populations can be sub-divided into temporally isolated subpopulations using earlier or later periods of the season for reproduction. T
De Jure Belli ac Pacis Libris Tres, av Hugo Grotius, och den westfaliska freden, i 1600-talets Europa, har ofta betonats av forskare som födelseplatsen för den moderna folkrätten. Denna studie har ämnat granska validiteten i dessa påståenden genom en rättshistorisk undersökning av omständigheterna kring texterna och en komparativ utredning dem emellan. Arbetets huvudsakliga syfte har varit att utfDe Jure Belli ac Pacis Libris Tres, by Hugo Grotius, and the Peace of Westphalia, in 17th century Europe, has often been highlighted as the birthplace of modern public international law. This study aims to review the validity of such statements through research of the legal history concerning the topic and through a comparative examination of the two works. The main purpose of the study have been
We realize strongly confined quantum dots (QDs) in InAs nanowires (NWs) by combining epitaxial crystal-phase control with chemical wet etching. A strong axial confinement is first introduced by growing closely spaced wurtzite (WZ) tunnel barriers in NWs to enclose a zinc blende (ZB) QD. The NW cross-section is then reduced by isotropic etching to obtain very small QDs, with a maximum observed char
No one wants to be at the wrong place at the wrong time. No one wants to be accused of having committed a crime one hasn't committed. No one wants to be innocently convicted. According to the presumption of innocence (article 6.2. in ECHR) everyone who has been charged with a criminal offence shall be presumed innocent until proved guilty according to law. It is important that the judge rememb
The following essays checks whether the Swedish stock market (represented by OMXS30) supports the weak efficiency of the EMH by observing whether the stocks contain a unit root and whether one can use trading strategies to create abnormal profits. The AR(1) model of the stock prices have a unit root coefficient very close to 1, thus they are trend stationary but have a very long memory. This model
The purpose of this study is to investigate the performance of traditional stop-loss rules and trailing stop-loss rules compared to the classic buy-and-hold strategy. The evaluation criteria of whether stop-loss strategies can deliver better results are defined as return and volatility. The study is conducted on daily equity returns data for stocks listed on the OMX Stockholm 30 Index during the t
Våld i samband med fotbollsmatcher har länge varit ett problem i Sverige. Den 30 mars 2014 nådde det sin kulmen när en Djurgårdssupporter misshandlades till döds i samband med en match mot Helsingborgs IF, vilket blev starten för en kris som drabbade både Helsingborgs IF och dess supporterförening Kärnan. Studien, som fokuserar på medlemsorganisationers kriskommunikation och organisations-samarbet
Background: Obesity early in life has been linked to increased risk of developing multiple sclerosis (MS). Leptin and insulin are both associated with obesity, making them suitable candidates for investigating this connection. Objective: To determine if leptin and insulin are risk factors for relapsing–remitting multiple sclerosis (RRMS). Methods: In this nested case–control study using blood samp
The purpose of the numerical study was to investigate the influence of three different natural gas compositions on the combustion behaviour of an Advanced Environmental Vortex (AEV) burner. The flow conditions apply to the AEV burners installed in the Siemens gas turbine SGT-800. Numerical simulations were carried out using the software Chemkin 4. Ignition temperatures, adiabatic flame temper
Faster bacterial biomass turnover is expected in water compared to soil, which would result in more rapid community adaption to changing environmental conditions, including temperature. Bacterial community adaptation for growth is therefore predicted to have larger seasonal amplitudes in lakes than in soil. To test this prediction, we compared the seasonal variation in temperature adaptation of ba
The interfacial nanostructure of the three most widely-studied Deep Eutectic Solvents (DESs), choline chloride:urea (ChCl:Urea), choline chloride:ethylene glycol (ChCl:EG), and choline chloride:glycerol (ChCl:Gly) at a Pt(111) electrode has been studied as a function of applied potential and water content up to 50 wt%. Contact mode atomic force microscope (AFM) force-distance curves reveal that fo
