Svarta Hål i Fysikens Historia
… på så vis fysikens heltäckande kvalitet som naturvetenskap. Genom sammanfattning av historia och förklaringar på frågeställande fenomen strävar detta arbete efter att inspirera kommande generation av vetenskapliga tänkare. Tack vare sitt mystiska och medryckande väsen kan svarta hål förse oss …

p38 MAPK Signalling in Endothelial Apoptosis
Endothelial apoptosis plays an important role in atherosclerosis, and a direct proapoptotic effect of chemotherapeutics on the tumour vasculature, emphasizes the great potency of antiangiogenic therapy in the treatment of cancer. We investigated signalling pathways in endothelial apoptosis induced …

Some Extensions of Poincaré-Bendixson Theory Applied to a Resonant Converter.
In this thesis existence and uniqueness of limit cycles are shown for a resonant converter, by extending Poincaré-Bendixson theory to non-smooth vector fields. We discuss relevant control theory and the role of simulations.

Signal Transduction and Gene Regulation in Cerebral Arteries Following Ischemia
The thesis consideres the molecular events that take place in the cerebral arteries following a stroke. The degree and temporal course of reperfusion following a stroke is pivotal for the survival of the neuronal tissue in the penumbra. Previous investigations have revealed upregulation of …

Virus tropism and neutralization response in SIV infection
Simian immunodeficiency virus (SIV) infections in macaques are commonly used as models to study the pathogenesis of human immunodeficiency virus (HIV). Both SIV and HIV normally use the CD4 receptor and an additional coreceptor for cell entry. The most common coreceptors used by HIV are CCR5 and …

Sustainable Development: Implementation in Urban Water Systems
As Sustainable development, a widely used but poorly understood term, challenges traditional scientific values such as prediction and control, scientists have tried to manipulate the concept to promote their own particular agendas. Thus, it has suffered from misrepresentation which has prevented …

On acoustic particle and cell manipulation in microfluidic systems
The combination of laminar flows in microfabricated channels and acoustic forces induced in ultrasonic standing wave fields offers new possibilities for advanced particle and cell manipulation in lab-on-a-chip applications as well as in relatively high throughput applications. Acoustic particle …
