Being acquainted with four of the most famous games in game theory, we will learn that players often are better paid off cooperating with each other, but that the structure of the game forces them to defect from cooperation. Only when confronted with the zero-sum game the players have no incentive to cooperate. In all the other games, cooperation is secured if the players commit themselves to adop
Charophytes play a critical role for the functioning of shallow lake ecosystems. Although growth of charophytes can be limited by many factors, such as temperature, nutrients and light availability, our understanding about concomitant effects of climate warming and other large-scale environmental perturbations, e.g. increases in humic matter content (‘brownification’) is still limited. Here we con
The TCF4 gene encodes for the basic helix–loop–helix transcription factor 4 (TCF4), which plays an important role in the development of the central nervous system (CNS). Haploinsufficiency of TCF4 was found to cause Pitt-Hopkins syndrome (PTHS), a severe neurodevelopmental disorder. Recently, the screening of a large cohort of medulloblastoma (MB), a highly aggressive embryonal brain tumor, reveal
BACKGROUND & AIMS: Our aims were to develop a method to accurately predict non-alcoholic fatty liver disease (NAFLD) and liver fat content based on routinely available clinical and laboratory data and to test whether knowledge of the recently discovered genetic variant in the PNPLA3 gene (rs738409) increases accuracy of the prediction. METHODS: Liver fat content was measured using proton magne
Carex humilis is a clonal sedge that can form distinct rings of densely aggregated ramets. We hypothesize that rings form because both production of new ramets and ramet dispersal are positively correlated to ramet size. This would lead to an overrepresentation of fast-moving and large ramets with high ramet production at the periphery, whereas slow-moving and small ramets with low ramet productio
Nasonia vitripennis is an emerging insect model system with haplodiploid genetics. It holds a key position within the insect phylogeny for comparative, evolutionary and behavioral genetic studies. The draft genomes for N. vitripennis and two sibling species were published in 2010, yet a considerable amount of transcriptiome data have since been produced thereby enabling improvements to the origina
Inhibition of mitochondrial permeability transition (mPT) has emerged as a promising approach for neuroprotection and development of well-tolerated mPT inhibitors with favorable blood-brain barrier penetration is highly warranted. In a recent study, 28 clinically available drugs with a common heterocyclic structure were identified as mPT inhibitors e.g. trifluoperazine, promethazine and nortriptyl
Optical wireless networks realized by means of gigabit optical wireless communication (OWC) systems are becoming, in a variety of applications, an important alternative, or a complementary solution, to their fiber-based counterparts. However, performance of the OWC systems can be considerably degraded in periods of unfavorable weather conditions, such as heavy fog, which temporarily reduce the eff
The most limiting factor in heart transplantation is the lack of donor organs. With enhanced prediction of outcome, it may be possible to increase the life-years from the organs that become available. Applications of machine learning to tabular data, typical of clinical decision support, pose the practical question of interpretation, which has technical and potential ethical implications. In parti
Insulin resistance causes compensatory insulin production, which in humans can eventually progress to β-cell failure and type 2 diabetes (T2D). This disease progression involves multi-scale processes, ranging from intracellular signaling to organ and whole-body level regulations, on timescales from minutes to years. T2D progression is commonly studied using overfed and genetically modified rodents
Sammanfattning I detta examensarbete besvarar jag frågan om svenska domännamn har ett immaterialrättsligt skydd. Fråga är intressant av flera aspekter. Rättsområdet är relativt ungt och behovet av domännamn uppstod så sent som i början på 1980-talet. Det nya systemet att adressera datorer på Internet fick namnet Domain Name System (DNS). Utvecklingen och spridningen av Internet har sedan dess variSummary in English In my thesis I answer the question whether any intellectual property rights protect Swedish domain names. This question is interesting due to several aspects. The legal area is relatively young and the demand for domain names occurred as late as in the early 1980s. The new system to address computers on the Internet was named Domain Names System (DNS). The development and distri
Skogsbruket är viktigt för svenskt näringsliv och står för ungefär 20 % av Sveriges totala export. Efterfrågan på virke blir därmed stor vilket resulterar i att avverkning sker ständigt, året om, på all typ av mark under alla olika sorters väderförhållanden. Ett stort problem inom skogsbruket är de markskador som ofta uppstår efter en slutförd avverkning. Markskador ändrar markens textur och egensForestry is important for Swedish industry and accounts for 20% of Sweden’s total export. The endless demand of wood results in logging all year round, but other aspects have to be taken into consideration. The ecology, forest recreation and the outdoor activities that the forest is providing is very important to preserve. A major problem in forestry is the soil damage after a successful harvest.
In recent years, different methods for fractionation of native milk fat globules with respect to particle size have been developed. This has been done in order to investigate if the size of the fat globules have any impact on the product functionality. The purpose of this master thesis was to develop a method for fractionation of native milk fat globules with respect to particle size and with focu
The settlement of marine organisms on boat hulls – known as biofouling – is a major concern in boating and over the years more or less environmentally harmful substances have been used to prevent it. However, the concept of biocide-free, so called foul-release coatings (FRC) that change the surface properties of the boat hull has gained more attention recently. In the present literature study, I h
Vätgas har potential i ett energilagringssystem eftersom det är en energibärare som är väldigt energirik och kan lagras i stor skala. Vätgas kan produceras enkelt via elektrolys av vatten och lagras i stora mängd under högt tryck, vid behov kan vätgasen sedan brännas i en kraftverksprocess och generera elektricitet. Då förbränning av vätgas med syrgas enbart bildar vattenånga kan ett förnybart eneHydrogen gas has potential to function as an energy storage solution due to its high energy content and its suitability for large scale storage. Hydrogen can be produced by water electrolysis and can be stored in large scale under high pressure, when needed the hydrogen can be burned in a thermal power plant to generate electricity. Since combustion of hydrogen with pure oxygen only yields steam,
This report is written to support SAAB Kockums AB in their investigations of whether it is necessary to replace their current Novec 1230 fire extinguishing system in electrical cabinets due to environmental restrictions, and what type of agent that would be a suitable replacement. The work focuses on determining consequences of a fire in an electrical cabinet regarding different aspects such as: f
The background to this master´s thesis is a decision by the regional council in Scania, Region Skåne, to preserve all medical records forever. Through the examination of documents and interviews with people associated with the regional archives, and by using Scandinavian institutional theory and time theory, this study looks into how the decision by the regional council is understood and implement
The relationship between capital structure and firm performance has been a recurring topic of discussion. Within this context, frameworks such as the Modigliani and Miller, Trade-Off, Market Timing, Pecking Order, Agency theories have been widely examined by researchers, offering diverse viewpoints on how capital structure decisions impact corporate performance in distinct industrial, regional and
