To a large extent, the thesis deals with a future solar telescope, the Large Earth-based Solar Telescope (LEST). The dynamical properties of the telescope, in particular its live optics system, have been investigated through implementation of a computer model, which has been used for simulations. The model includes the various parts of the telescope, as well as various image degrading effects. Of

Körsång och kör som fenomen är genuint förknippade med frågor om kulturens och kulturers uppkomst, utveckling och förändringsprocesser. Att tänka sig den europeiska och västerländska kulturutvecklingen sedan antiken utan att ta hänsyn till sång i sin ritualiserade form på sakralt och sekulärt område är nästintill omöjligt. Sångens position och funktion i moderna civilsamhällen är annorlunda än i f

Popular Abstract in Swedish SVENSK SAMMANFATTNING Den kliniska effekten av läkemedel som administreras till näsa eller lunga beror på läkemedlets egenskaper och på dess lokala deposition. Depositionsstudier är därför värdefulla för att kunna karakterisera olika beredningar. Depositionen påverkas av partiklarnas storlek och hastighet, genom att stora partiklar med hög hastighet ger upphov till en hThe local deposition, pharmacokinetics, and systemic activity of inhaled and intranasal glucocorticosteroids in different formulations and devices(ICSs) has been investigated. After nasal administration of the ICS budesonide (Bud), the systemic availability (F) was found to be significantly higher from an aqueous pump spray and from the powder inhaler Turbuhaler, than from a pressurized metered do

This is the second annual report for the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedi

Bioprocess monitoring and control is a complex task that needs rapid and reliable methods which are adaptable to continuous analysis. Process monitoring during fermentation is widely applicable in the field of pharmaceutical, food and beverages and wastewater treatment. The ability to monitor has direct relevance in improving performance, quality, productivity, and yield of the process. In fact, t

To produce fuel from gasified biomass is a way to manufacture carbon dioxide neutral fuels for transport purposes. The biomass is gasified by heat in a gasification unit, with or without nitrogen, and the resulting mixture consist of hydrogen, carbon dioxide, carbon monoxide, methane, steam, higher hydrocarbons in low concentration and tars. The gas will also contain nitrogen, argon, ammonia, hydr

Pay-What-You-Want (PWYW) pricing schemes are popular in certain industries and not others. We model the seller's choice of pricing scheme under various market structures assuming consumers share their surplus. We show that the profitability and popularity of PWYW depend not only on consumers' preferences, but also on market structure, product characteristics and sellers' strategies. While there is
