This dissertation discusses various issues relating to Iron Age settlements in the area around the central place of Uppåkra. Most of the sites have been excavated by contract archaeology. The discussion begins with a presentation of the material from the houses in the settlements, detailing the different construction types and discussing the functions and chronological aspects of the houses. The d
BACKGROUND: The tau-PET radiotracer [18F]flortaucipir enables in vivo detection of tau pathology in Alzheimer's Disease (AD) and has recently been FDA- and EMA-approved for clinical use. To support its implementation, we assessed tau-PET's positive predictive value (PPV) and negative predictive value (NPV) for clinico-pathological AD while accounting for age, amyloid-status, and pre-PET diagnostic
Background: Myocardium at risk (MaR) can be evaluated by cardiovascular magnetic resonance (CMR) imaging using contrast-enhanced steady state free precession (CE-SSFP) in patients after ST-elevation myocardial infarction (STEMI). However, CE-SSFP utilizes gadolinium contrast, which is contraindicated in patients with severe renal insufficiency. Native T1-mapping is a non-contrast CMR method which
Ultrarelativistic heavy-ion collisions, which take place at particle accelerators like the BNL Relativistic Heavy Ion Collider (RHIC) and the CERN Large Hadron Collider (LHC), are known to produce a strongly-interacting, fluid-like state of matter referred to as the Quark-Gluon Plasma (QGP). Despite the medium’s short lifetime of approximately 10-23 s, its presence is known to influence particle p
X-linked retinoschisis (XLRS) is a congenital progressive inherited retinal disease that affects the entire retina and is one of the more common causes of vision loss from retinal degeneration affecting young men,. The progression is variable but seems to be relatively stationary in the ages 6 to 25 years. Patients with XLRS lack a functional retinoschisin protein in the eye, because of mutation i
Svensk sammanfattningAvhandlingens syfte har varit att studera utvecklingen av en könskromosom i realtid genom att simulera dess framväxt i en hermafroditisk plattmask i laboratoriet. Jag gjorde detta genom att selektera på dels honlig fitness (fitness via ägg), dels hanlig fitness (fitness via spermier) med hjälp av en genetisk markör, som agerade som en könsbestämmande gen. Detta ska efterlikna Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. Sexually antagonistic alleles are a type of genetic variation that increases fitness for one sex while being detrimental for the other sex. Recombination arrest around the SDR and gen
Values lie at the core of landscaping processes. In human geography, the concept of landscape describes the way in which societies relate to space through collectively interacting with their environment. Landscapes are a way of seeing and perceiving physical space, assigning meaning to it, and shaping it by giving materiality to imaginations. Values constitute the nodes of the society-landscape ne
In recent years, there has been a surge in attention towards biodegradable polymer films, driven by the growing environmental awareness concerning the harmful effects of petroleumbased plastics. The maize protein zein, a by-product from wet milling processes, has shown potential to work as hydrophobic coating. The aim of this study has therefore been to find the most promising process conditions f
Background Dietary intervention is an effective way to prevent pandemic non-communicable diseases such as obesity and type 2 diabetes which can probably raise the risk of depression and Alzheimer's disease. Although considerable numbers of intervention studies focus on metabolic effects and physiological benefits of the intake of plant lipids, the function in appetite, mood, and cognition modu
The banking industry is getting more data driven and one of the main drivers of this is the Open Banking phenomenon. Open Banking allows account holders to digitally transfer their banking data from their bank to third party companies, it also allows third party companies to initiate payments on behalf of an account holder. Open Banking has been growing in importance in recent years and creates ne
Wetlands are valuable ecosystems, and assets for human life, that must be regularly monitored, starting with accurately mapping their location and extent. However, an updated national inventory of wetlands is needed. The availability of multi-source data, and advanced machine learning algorithms in Google Earth Engine (GEE) offers excellent opportunities to map wetlands on a country-wide scale. Th
An increased understanding of the negative impacts of animal-based proteins, on both environment and health, has led to a rise in the demand for plant-based proteins. To meet the demands, conventional crops must be efficiently utilized. One possible crop is oat which is a good source of protein, fibre, and fat, but is currently mainly used for animal feed. To better utilize the proteins in oat, th
Introduction and aim Atherosclerotic stenosis located at the carotid bifurcation accounts for 10% − 20% of all Transient Ischemic Attacks (TIA) and ischemic strokes, which occurs when Atherosclerotic stenosis, or so-called plaque, ruptures. The current method to evaluate carotid atherosclerotic stenosis is to measure the degree of stenosis. Strong markers for plaque rupture lies in the plaque cont
Konflikt är en grogrund för könsbaserat våld. Tidigare diskriminerande strukturer förstärks och mynnar ut i våld inom ramen för konflikten. I komplexa kontexter präglade av religiösa, etniska och/eller politiska slitningar förstärks vissa individers utsatthet. Under ISIS attack mot Sinjar-regionen i norra Irak utgjorde den religiösa minoritetsgruppen Yazidier måltavlan. Genom ett systematisk förfaConflict is a breeding ground for gender-based violence. Previous discriminatory structures are reinforced and often result in conflict-related gender-based violence. In complex contexts characterized by religious, ethnic and / or political frictions, the vulnerability of some individuals is exacerbated. During the ISIS attack in the Sinjar region in northern Iraq, the religious minority group Yaz
Popular Abstract in Swedish Datorgrafik handlar om att övertyga betraktaren. En huvuduppgift är att generera verklighetstrogna bilder utifrån tredimensionella modeller. Med hjälp av datorer simuleras hur dessa modeller interagerar med ljus. Betraktaren skall helst inte reflektera över om bilden han ser är ett fotografi eller en helt och hållet genererad bild. I denna avhandling presenteras algoritModern graphics hardware pipelines create photorealistic images with high geometric complexity in real time. The quality is constantly improving and advanced techniques from feature film visual effects, such as high dynamic range images and support for higher-order surface primitives, have recently been adopted. Visual effect techniques have large computational costs and significant memory bandwid
Load problems in electricity markets occur both on the supply and demand side and can have technical, economic and even political causes. Commonly, such problems have been solved by expanding production and/or distribution capacity, importing electricity or by load management. Load management is a techno-economic measure for harmonizing the relations between supply and demand sides, optimizing pow
Aerosol particles have always been present in the atmosphere, arising from natural sources. But it was not until recently when emissions from anthropogenic (man made) sources began to dominate, that atmospheric aerosols came into focus and the aerosol science in the environmental perspective started to grow. These sources emit or produce particles with different elemental and chemical compositions
