We studied in chimeric EGFP-Photinus luciferase HeLa cells the expression of fluorescence and luminescence in different cell culture conditions (medium with or without Serum, static or dynamic conditions, in suspension or on microcarriers) as a model to follow the productivity of a recombinant protein. By studying the effect of Butyrate known as general but unpredictable stimulating agent for prot
Popular Abstract in Swedish Syftet med denna avhandling var att studera blandningsprocessen i statiska mixrar vid laminärt flöde och i rör vid förträngning av vätskor med olika fysikaliska egenskaper. En numerisk metod och ett tillvägagångssätt för att karaktärisera statiska mixrar har utvecklats. Med hjälp av den utvecklade metoden och numerisk strömningsberäkning (CFD) har effekten på blandningThe objective of the present work was to investigate the mixing process in static mixers under laminar flow conditions, and in pipes during the displacement of dissimilar liquids. A numerical scheme and a method of characterizing static mixers were developed. The effects of changes in geometry, flow rate, viscosity ratio and volumetric flow rate ratio on the mixing process were investigated using
Popular Abstract in Swedish Modern gastroenterologi är till stora delar helt beroende av resultat från gastrointestinal endoskopi och många av de sjukdomar som hänförs till denna specialitet kan också behandlas med modern endoskopisk och minimal invasiv teknik. Gastroskopi är förstahandsundersökning av patienter med såväl kroniska som akuta symptom från övre gastrointestinalkanalen. Den gastroskopChromoendoscopy, endoscopic tissue staining, is an adjunctive method using chemical agents applied to the mucosal surface in order to aid gastrointestinal endoscopic diagnosis and therapy. Acid producing mucosa in the GI tract may be visualized endoscopically by Congo red staining in combination with stimulation of gastric acid production. Congo red is a reactive indicator dye that changes color f
Popular Abstract in Swedish Genom århundradena har ingenjörskonsten och naturvetenskapen genomsyrats av en önskan att förstå och kontrollera den materia som omger oss. All materia, till exempel träd, byggnader och mobiltelefoner, består av olika slags atomer som är arrangerade i en mängd olika strukturer. Från människans första försök att tillverka redskap genom att manipulera flintstenar och metaThis thesis investigates different methods for treating strongly correlated systems, and discusses their respective strengths and weaknesses. Many of the results presented in this thesis come from comparing the different methods and approximations to exact results. Paper I: We studied the real-time dynamics of a trapped fermion gas, as it expands after removal of a trapping potential. Paper II: We
The university programmes are basically nationally based, developed from the historical needs of specific need of a society. The Bologna process is challenging the educational market mainly at post-graduate level. The exchange of students is still limited to a reduced number of curious and ambitious persons, many with a high interest for cultural exchange – the ‘exotic dimension’. Individual caree
We investigate whether acquiring more education when young has long-term effects on risk-taking behavior in financial markets and whether the effects spill over to spouses and children. There is substantial evidence that more educated people are more likely to invest in the stock market. However, little is known about whether this is a causal effect of education or whether it arises from the corre
Many animals, and all plants and fungi, produce vegetative offspring, i.e. descendant individuals that originate from mitotic, rather than meiotic, cell lineages.

The overall purpose of this work is to increase our understanding of the e
This paper proposes a technique for letting end users build pervasive applications by combining services on networked devices. The approach avoids relying on standardized service interfaces which are deemed too limiting, and instead makes use of migratable user interfaces and scripted combinations of services.
