1. Laser on kinetic operator
Sammanfattning : This thesis highlights a variety of aspects within the field of mobile robots. The hinge is system architecture for mobile robots. For a mobile robot to be put into operation all necessary systems have to be functioning and control mechanisms have to be established. The robot may be set to operate autonomously as well as remotely controlled. LÄS MER
2. Kinetics of proton and electron transfer in heme-copper oxidases
Sammanfattning : Heme-copper oxidases are transmembrane proteins that are found in aerobic and anaerobic respiratory chains. During aerobic respiration, these enzymes reduce dioxygen to water. The energy released in the reaction is used to transport protons across a biological membrane. LÄS MER
3. Flash Diffractive Imaging in Three Dimensions
Sammanfattning : During the last years we have seen the birth of free-electron lasers, a new type of light source ten billion times brighter than syncrotrons and able to produce pulses only a few femtoseconds long. One of the main motivations for building these multi-million dollar machines was the prospect of imaging biological samples such as proteins and viruses in 3D without the need for crystallization or staining.

4. Statistical processing of Flash X-ray Imaging of protein complexes
Sammanfattning : Flash X-ray Imaging (FXI) at X-ray Free Electron Lasers (XFELs) is a promising technique that permits the investigation of the 3D structure of molecules without the need for crystallization, by diffracting on single individual sample particles.In the past few years, some success has been achieved by using FXI on quite large biological complexes (40 nm-1 μm in diameter size).

5. Imaging Living Cells with an X-ray Laser
Sammanfattning : Imaging living cells at a resolution higher than the resolution of optical microscopy is a significant challenge. Fluorescence microscopy can achieve a degree of super-resolution via labeling cellular components with a fluorescent dye. LÄS MER
