Environmental impact and security of supply has fuelled a shift in the power mix of power systems today. Traditionally used fossil fuel gives more and more space to the development of renewables in an effort to comply with strict international standards regarding CO2 emissions and secure energy supply. Wide geographical spread of renewable resources indicates that HVDC technology is most suitable

As requirements regarding energy efficiency are getting tougher, buildings in the arctic, as well as the rest of the world, need to be more energy efficient without compromising a good indoor climate. This paper presents measured moisture supply and occupancy level in a Swedish Arctic multi-family building. Measurements were done during one year with readings every 30 minutes in a building consist

The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. The model was used to analyse an existing system in Denmark with 15 connected single-family detached houses. Each of the houses has a

Denna uppsats undersöker de sedvanerättsliga reglerna om immunitet för statschefer och andra högt uppsatta statsrepresentanter. Syftet är att göra en övergripande kartläggning av reglernas innehåll som möjliggör korrekt rättstillämpning i framtiden. Genom att granska konventioner, kodifieringar, rättsfall och doktrin om ämnet, samt genom att undersöka det pågående kodifikationsarbetet, kartläggs rThis essay examines the rules of immunity for heads of state and other high-ranking state officials under international law. The aim is to create a comprehensive outline of the content of the rules, enabling a more accurate and legal-ly sound practice in the future. Through reviewing conventions, codifications, legal cases and legal doctrine on the subject, and through examining the current codi

Hemicellulosic materials are among the most abundant renewable resources on earth, but have not yet found any broad application. However, if a cost effective extraction method is developed, hemicelluloses have the potential to be utilized to a much larger extent in the future. Ultrafiltration (UF) is a low energy demanding separation process that can be used to concentrate and purify hemicellulose

Studying the effects of the climate change on buildings contains two major fields: energy consumption and durability. In the field of durability the moisture effects on the building play a significant role. In Sweden the last 10-15 years have been mild and wet compared to previously. Precipitation increased considerably during the period (+11 %), whereas temperature increase were weaker (+ 0.7 oC)

As the total cost of renewable electricity falls lower than the price of fossil fuel, not only can electricity be used to replace fossil fuels using batteries in vehicles but it can also be used to produce fuels. This makes it possible to replace fuels in sectors not easily directly electrified. It also provides new ways of balancing the electricity system. When renewable electricity is cheap a lo

Handelsrätt är ett juridiskt ämne, som handlar om de regler och normer som har betydelse för ekonomisk verksamhet, nationellt såväl som internationellt. Handelsrätten reglerar företagens verksamhet och är alltså den samlande beteckningen på de olika delar av juridiken som är speciellt viktiga för företaget. Hit räknas t ex avtalsrätt, bolagsrätt, skatterätt, arbetsrätt, immaterialrätt och konkurreBusiness law is a legal discipline focused on the norms and rules that impact the business sector, both nationally in Sweden and internationally. Business law regulates companies’ operations and is an umbrella term covering the braches of law that are especially important for businesses. This covers, for example, contract law, corporate law, tax law, labour law, intellectual property law and compe

Background & Aims: Glucagon-like peptide-2 (GLP-2) is a 33-amino acid peptide hormone secreted by enteroendocrine cells in response to nutrient ingestion. GLP-2 stimulates crypt cell proliferation leading to expansion of the mucosal epithelium; however, the mechanisms transducing the trophic effects of GLP-2 are incompletely understood. Methods: We examined the gene expression profiles and gro

Increasing efforts to produce power from renewable resources and improve the efficiency of current industrial processes have turned the spotlight on organic Rankine cycles (ORC). The use of refrigerant mixtures in these cycles offers a wide range of possibilities for fluid selection and optimization. Moreover, zeotropic mixtures are reported to yield better cycle performances due to their better t
