Sammanfattning : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. LÄS MER
Sammanfattning : The aim of this thesis is to validate methods for estimation of intracranial volume in magnetic resonance images and to improve our understanding of the effect of intracranial volume normalization. To achieve the first part of the aim, 62 gold standard estimates of intracranial volume were generated by manually segmenting 1. LÄS MER
Sammanfattning : With the increasing demand of transportation, biofuels play a fundamental role in the transition to sustainable powertrains. For the increased uncertainty of biofuel combustion properties, advanced combustion control systems have the potential to operate the engine with high flexibility while maintaining a high efficiency and robustness.

4. Ethanol-mediated effects on astroglial cells in primary culture. With a focus on acute changes in intracellular Ca2+, cell volume, actin filaments, and gap junction coupling
Sammanfattning : The astroglial cells are abundant in the central nervous system (CNS), where they control and regulate the homeostasis of the extracellular milieu. A change in astroglial cell volume, mediated through activation of neuroactive substances or changes in osmolarity, leads to changes in the size and geometry of the extracellular space volume, which could affect the diffusion and concentration of neuroactive substances.
