This thesis is trying to identify and give solutions for the problems occurring in polyurethane sport surfaces in Iraq where the climate is extremely warm and dusty. One of the most important problems (called the ‘maintenance’ problem) is that the polyurethane sport surface looks very dirty because of the dust, a couple of weeks after installation of the surface the dust particles penetrates the s
Ultrasound optical tomography enables noninvasive characterization of tissue and lesions up to 5 cm below the skin surface, by enhancing diffuse optical tomography with ultrasound focusing resolution and an increased number of measurement points. For optimal clinical imaging, it is essential to be able to reconstruct tissue optical properties in real time during in vivo measurements, and therefore
The electricity market exhibits significant uncertainty arising from rapid fluctuations in prices, variations in load demand, and the intermittent nature of renewable energy resources. Effectively managing residential energy under these dynamic conditions is a challenging task. Demand Response (DR) offers a practical solution by enabling the flexible scheduling of energy consumption in response to
One organizational innovation introduced by the clean energy for all Europeans package (CEP) is that of the energy community (EC), including the renewable energy community (REC) and citizen energy community (CEC). The translation of related directives into national legislation is underway in Sweden, and the Swedish Energy Market Inspectorate (Ei) has proposed a new law on ECs, which has been sent

Background ST-elevation myocardial infarction (STEMI) occurs as a result of rupture of an atherosclerotic plaque in the coronary arteries. Limited data exist regarding the impact of culprit coronary vessel on hard clinical event rates. This study investigated the impact of culprit vessel on outcomes after primary percutaneous coronary intervention (PCI) of STEMI.Methods A total of 29 832 previousl
Denmark is currently undertaking extensive groundwater mapping surveys in designated water interest areas. The mapping objectives include vulnerability assessments, delineation of existing aquifers, and localization of new deeper lying aquifers. Airborne electromagnetics are employed for regional mapping to depths of hundreds of meters. Resistivity profiling and pulled-array geo-electrics are util
This study focuses on the trends and the causes of variation in actual evapotranspiration (AET) around the warming hiatus over China by a comprehensive analysis applying various temporal–spatial methods. It is observed that the annual AET showed a different trend around 2000 for China as a whole. By employing segmented regression analysis for detecting warming hiatus points, high temporal inconsis
Objectives: To assess the prevalence of reported and unreported incidental pulmonary embolism (iPE) in patients with cancer, and to evaluate an artificial intelligence (AI) algorithm for automatic detection of iPE. Methods: Retrospective cohort study on patients with cancer with an elective CT study including the chest between 2018-07-01 and 2019-06-30. All study reports and images were reviewed t
Popular Abstract in Swedish Retrovirus är en typ av virus som finns hos både människor och djur. Detta virus sprider sig genom att en virus partikel tar sig in i en cell och sedan integrerar sin virala arvsmassa in i cellens arvmassa, DNA. Retrovirusets arvsmassa är från början RNA men skrivs sedan om till DNA för att kunna integreras. I molekylärbiologins barndom trodde man att det genetiska flödThe human genome contains genetic elements which are more or less similar to infectious retroviruses. These are called human endogenous retroviruses (HERVs) and are thought to be remnants of infections in the primate lineage. Most of them have been inserted 10 to 60 million years ago but have at different time points spread in the genome via intracellular retrotransposition and make up as much as
This explorative literature review aims to examine the content and methodologies of recent empirical studies on the aspirations of youth in situations of migration in Europe. The search yielded 30 peer-reviewed social science publications in English for the period 2010–2022, including both intra-European migrants ages 10–24 and youth with backgrounds from outside Europe. Contextual analysis was us
Aims Previous studies on disparities in healthcare and outcomes have shown conflicting results. The aim of this study was to assess differences in baseline characteristics, management, and outcomes in myocardial infarction (MI) patients, by country of birth. Met hods a nd results In total, 194 259 MI patients (64% male, 15% foreign-born) from the nationwide SWEDEHEART (The Swedish Web-system for E
Introduction: The relationship between left ventricular (LV) ejection fraction (EF) and LV myocardial scar can identify potentially reversible causes of LV dysfunction. Left bundle branch block (LBBB) alters the electrical and mechanical activation of the LV. We hypothesized that the relationship between LVEF and scar extent is different in LBBB compared to controls. Methods: We compared the relat
The work presented here is based on two papers, both pertaining to perturbation-based control strategies in industrial fed-batch fermentation processes. The first paper describes a new control strategy for avoiding overflow metabolism in the exponential growth phase of a fermentation, based on analysis of the frequency spectrum of the dissolved oxygen measurement following a periodic perturbation
Popular Abstract in Swedish I gruppen huvudhalscancer ingår tumörer i övre luftvägar och svalg. Riskfaktorer för huvudhalscancer är rökning och alkoholöverkonsumtion. Under de senaste 20-30 åren har det skett en påtaglig ökning av insjuknandet, 4-5% per år, i det som kallas orofaryngeal cancer. Orofaryngeal cancer utgår från mellansvalget; mandlar, tungbas och mjuka gommen. Ökningen sammanfaller mThe treatment for head and neck squamous cell carcinoma (HNSCC) is surgery or (chemo)radiotherapy +/- surgery. Side effects related to therapy are long lasting and adversely affects quality of life. The incidence of oropharyngeal cancer is increasing and patients commonly present an advanced tumour stage with neck metastases at the time of diagnosis. The treatment protocol previously comprised rad
We present multiple-epoch radial-velocity observations for 104 stars in a field of the intermediate-age open cluster IC 4651 to . Only 13 stars (13%) of the full sample are field stars. From the 44 single member stars we find a mean radial velocity of , and the 12 single red-giant members yield a true radial-velocity dispersion of . Of the 19 giant members, 7 (37%) are spectroscopic binaries with
In the framework of the ESO Large Programme ``First Stars'', veryhigh-quality spectra of some 70 very metal-poor dwarfs and giants wereobtained with the ESO VLT and UVES spectrograph. These stars are likelyto have descended from the first generation(s) of stars formed after theBig Bang, and their detailed composition provides constraints on issuessuch as the nature of the first supernovae, the eff
Popular Abstract in Undetermined Denne afhandling præsenterer en ny udlæsnings metode udviklet til cantileverbaserede sensorer. Cantilevere er tynde vipper, der er fastgjorte i den ene ende, og som igennem de seneste ti °ar har vist sig at være en interessant ny type bio/kemisk sensor. Den specifikke genkendelse af et kemikalie viser sig ved at cantileveren bøjer som følge af det skabte overfladesThis thesis presents a novel read-out method developed for cantilever-based sensors. Cantilevers are thin beams clamped at one end and during the last 10 years they have emerged as an interesting new type of bio/chemical sensor. The specific recognition of a chemical manifests itself as a bending of the cantilever from the generated surface stress. Conventionally the read-out used for this type of
Background: The need for a mobile workforce inevitably means that the length of the total work day (working and traveling time) will increase, but the health effects of commuting have been surprisingly little studied apart from perceived stress and the benefits of physically active commuting. Methods: We used data from two cross-sectional population-based public health surveys performed in 2004 an
