Context. The star cluster initial mass function is observed to have an inverse power law exponent around 2, yet there is no consensus on what determines this distribution, and why some variation is observed in different galaxies. Furthermore, the cluster formation efficiency (CFE) covers a range of values, particularly when considering different environments. These clusters are often used to empir
Tamoxifen prevents recurrence of breast cancer and is also approved for preventive, risk-reducing, therapy. Tamoxifen alters the breast tissue composition and decreases the mammographic density. We aimed to test if baseline breast tissue composition influences tamoxifen-associated density change. This biopsy-based study included 83 participants randomised to 6 months daily intake of placebo, 20, 1
Environmental aspects have during the last years made electric vehicles an interesting competitor to the present internal combustion engine driven vehicles. For a broad introduction of pure electric vehicles, a battery charging infrastructure is deemed necessary. However, to build and maintain such an infrastructure is costly. Active power line conditioning capabilities could be included in the ba
Popular Abstract in Swedish Konceptet fjärrvärme inbegriper central värmeproduktion från vilken värme distribueras ut till de enskilda förbrukarna via ett rörsystem. Ett grundläggande krav, med hänsyn till fjärrvärmens konkurrenskraft, är att vinsten som görs i den storskaliga värmeproduktionen, jämfört med lokal värmeproduktion, överstiger kostnaderna för värmedistributionen. DistributionskostnadThe concept of district heating (DH) involves centralised heat production where heat is distributed to consumers via a piping network. It is essential that benefits achieved from concentrated, large-scale production instead of local production in each building exceed the costs associated with heat distribution. Since the distribution cost per delivered kWh increases as the heat density of an area
Nuclear medicine uses radioactive pharmaceuticals for diagnostic or therapeutic purposes. The ionizing radiation emitted from the radiopharmaceutical is partially absorbed within the patient's body and internal dosimetry is the method to estimate the absorbed dose to a tumour or risk organ. This is of special importance in radiopharmaceutical therapy (RPT), where particle-emitting radionuclides ar
Popular Abstract in Swedish Strålbehandling av cancerpatienter sker idag med avancerad teknik och utrustning. Förberedelserna inför behandlingen är omfattande och kräver medverkan av flera olika personalkategorier och övervakning via datoriserade verifikationssystem. I varje led i förberedelsekedjan finns en potentiell risk för avvikelser, vilka kan vara både systematiska eller tillfälliga i sin nThe aim of this work was to develop, implement and evaluate an independent system with which to calculate the absorbed dose, delivered by high-energy X-ray beams, to the prescription point and the depth of dose maximum. The introduction of such a system in the clinical routine may help ensure high-quality treatment and avoidance of errors which may jeopardise the clinical outcome of the treatment

Popular Abstract in Swedish Eld har fascinerat människan i alla tider. Att sitta och värma sig vid en lägereld, sjunga sånger eller bara titta på hur elden rör sig är något de flesta har upplevt. Hur många har egentligen funderat på var värmen kommer ifrån, hur den gula färgen uppstår eller vad eld egentligen består av? Några av frågorna finns det nu svar på, men fortfarande finns det mycket att uThe work presented in the thesis covers the use of laser-induced fluorescence (LIF) and photofragmentation laser-induced fluorescence (PFLIF) with short laser pulses to determine species concentrations in different combustion environments. To attain quantitative species concentrations using LIF investigations of the influence of collisional quenching on the fluorescence signal strength is of vital

Popular Abstract in Swedish Denna avhandling gäller glibenklamid som är vårt vanligaste läkemedel för oralt bruk i behandlingen av diabetes mellitus, typ 2 (åldersdiabetes). Glibenklamids upptag, fördelning, omsättning och utsöndring har studerats i detalj hos friska människor samt hos patienter med diabetes. Därtill har läkemedlets och dess metaboliters kinetik relaterats till farmako-dynamiska eGlibenclamide (Gb) is the most commonly employed sulphonylurea worldwide for the treatment of non-insulin-dependent diabetes mellitus (NIDDM). There has been uncertainty concerning its pharmacokinetics (PK) and pharmacodynamics (PD). Numerous long-lasting hypoglycemic reactions, which have sometimes been fatal, have been reported and have been difficult to reconsile with an allegedly short elimina
Glulam arches can be used when designing structures with large spans such as halls or arenas. Wood has low density compared to steel and concrete which keeps down the dead weight of the structure. The cross section of glulam arches is often built up as a box-section for efficiency reasons. However, wood shows strongly orthotropic behavior where maximum allowed stress perpendicular to grain is only
Background: Starch is a well-studied material, produced by plants in granules to store energy. Starch finds a lot of applications in day-to-day life, in the food and pharmaceutical industry. This project was focusing on the utilization of starch retrogradation and the ability to form aqueous two-phase systems to prepare microspheres from the starch of different botanical sources and characterize t
Relative Energy Deficiency in Sport (RED-S) is a condition arising when dietary energy intake is insufficient to meet the combined demands of training and normal physiological functions. RED-S negatively impacts bone health, and increases the risk of stress fractures. Yet, its effects on bone matrix organization and overall bone quality is not well understood. Collagen and the osteocyte cells'
Sheet-metal forming involves a complex strain distribution over the part. The strains consist of tension, compression, and a mix of both. A geometry has been developed, the X-Die, in order to gain insight into the strain behavior of different materials. The X-Die enables strain paths far into the tension/compression region, thus creating the possibility to extend the experimental base both for def

Background: Strenuous exercise has been associated with functional and structural cardiac changes due to local and systemic inflammatory responses, reflecting oxidative, metabolic, hormonal, and thermal stress, even in healthy individuals. We aimed to assess changes in myocardial structure and function using cardiovascular magnetic resonance (CMR) imaging in master triathletes early after a full-d
Aims/hypothesis: It is well established that physical activity, abdominal ectopic fat and glycaemic regulation are related but the underlying structure of these relationships is unclear. The previously proposed twin-cycle hypothesis (TC) provides a mechanistic basis for impairment in glycaemic control through the interactions of substrate availability, substrate metabolism and abdominal ectopic fa
The aim of the present thesis was to study temperament traits and their relationships to psychiatric diagnoses, suicidal behavior and a number of biological measures in a sample of hospitalized suicide attempters. The subjects showed a bimodal distribution on the Validity scale from the Marke-Nyman Temperament (MNT) inventory, with a large subgroup showing low Validity. Cluster analyses of the sc
