1. Electrophoretic migration of DNA in pluronic gels
Sammanfattning : .... LÄS MER
2. On the Optics and Surface Physics of Liquid Crystals
Sammanfattning : Good knowledge about optics and surface physics of liquid crystals is indispensable when utilising them for applications, such as liquid crystal displays (LCDs). However, they are also two central subjects in fundamental research on liquid crystals. LÄS MER
3. DNA Electrophoresis: Optical Probing and Microscopic Imaging to Understand Separation Mechanisms
Sammanfattning : The aim of this work was to combine spectroscopic, mobility, and fluorescence microscopy studies to elucidate the mechanisms behind DNA electrophoresis, a method to separate DNA molecules according to size. The microscopy studies require staining of the DNA with a fluorescent dye. LÄS MER
4. Keratinocyte differentiation. Involvement of the growth hormon (GH)/insulinlike growth factor1 (IGFI) axis and IGF1 post receptor signaling
Sammanfattning : At cellular level, little is known about the genes that regulate keratinocyte differentiation andproliferation. Psoriasis is regarded as a T-cell mediated inflammatory disease with hyperproliferativekeratinocytes. LÄS MER
5. The Flexoelectro-Optic Effect in Cholesteric Liquid Crystals
Sammanfattning : The flexoelectrooptic effect in cholesteric liquid crystals is based on a linear coupling of the medium with an applied electric field. The electric field causes the optic axis, which is coinciding with the helix axis of the hardtwisted cholesteric (pitch... LÄS MER
