1. Saturated planar laser-induced fluorescence using sinusoidal intensity modulation
Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenSammanfattning : Saturated laser-induced fluorescence (saturated LIF) has been the topic of some research, however mainly regarding laser diagnostic methods conducted on flames. A few papers have discussed saturated LIF with the purpose of producing saturation curves of different fluorescent elements. LÄS MER
2. Active dielectrophoretic trapping for deterministic single-cell encapsulation in droplet microfluidics
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The research work focuses on optimizing various parameters for controlling cells using negative dielectrophoresis and entrapping them in droplet microfluidics. This is achieved by developing a conductivity medium, combining CytoRecovery, BSA, and EDTA, to maintain a steady count of single cells with good viability over an extended period. LÄS MER
3. Improving image quality of a streak camera using periodic shadowing
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : Stray light suppression using a method inspired by lock-in amplification, called periodic shadowing, is examined and demonstrated for a measurement involving a streak camera. The experiment consists of resolving the fluorescent decay of the dye Rhodamine B (RhB) and examining both the rise and the decay of the fluorescence. LÄS MER
4. Development of a single-molecule tracking assay for the lac repressor in Escherichia coli
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för cell- och molekylärbiologiSammanfattning : Gene regulation by transcription factors are one of the key processes that are important to sustain all kinds of life. In the prokaryote Escherichia coli this has shown to especially crucial. The operator sequence to which these transcription factors bind to are very small in comparison to the whole genome of E.

5. Understanding product build up at packaging material surface to address food waste
Master-uppsats, Lunds universitet/FörpackningslogistikSammanfattning : Difficulty to empty the package is one of the main reason of food waste in yoghurt at consumer level with an estimated 5-10% of product residue being left on the packaging material. The phenomenon of product build up is explained by numerous hypothesis. However, these studies are empirical in nature. LÄS MER
