31. A Pilgrimage to the Past : Johannes Bureus and the Rise of Swedish Antiquarian Scholarship, 1600-1650
Sammanfattning : At the end of the eighteenth century, Edward Gibbon described the antiquarian scholars of previous generations as men of “profound learning and easy faith.” His exemplar was the Swedish polymath Olof Rudbeck, who in a series of frantic and combative tomes sought to portray Sweden as the model for Plato’s Atlantis and the seething cultural cauldron from which Western civilization had emerged.

32. Extending the Reach of Accurate Wavefunction Methods
Sammanfattning : Multiconfigurational quantum chemistry methods, and especially the multiconfigurational self-consistent field (MCSCF) and multireference perturbation theory (MRPT2), are powerful tools, particularly suited to the accurate modeling of photochemical processes and transition metal catalysis. However, they are limited by their high computational cost compared to other methods, especially density functional theory. LÄS MER
33. Pathophysiological impact of targeting the ROS-p53 axis
Sammanfattning : The goal of this PhD thesis was to define the importance of the interplay between reactive oxygen species (ROS) and their activation of the tumor suppressor p53 in development and disease. We addressed this question using molecular biology and biochemical techniques together with mouse genetics and bioinformatics. LÄS MER
34. Combining mass spectrometric tissue imaging with conventional histology : focus on Alzheimer’s disease
Sammanfattning : Historically, most scientific discoveries have been accompanied by previous technological innovation. Representative examples are the introduction of gene sequencing technologies, which allowed for the mapping of the human genome, or the constant improvement in the microscopy field that lead to the introduction of modern multiphoton imaging techniques, allowing for live imaging of body organs in animal specimens.

35. Valley-Polarized Charge Transport in Diamond
Sammanfattning : Diamond is a wide bandgap semiconductor with extreme properties such as high thermal conductivity, high breakdown field and high carrier mobilities. These properties together with the possibility to synthesize high purity Single-Crystalline (SC) diamond by Chemical Vapor Deposition (CVD), makes it a really interesting material for electronic devices.
