1. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus
Sammanfattning : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. LÄS MER
2. Adult hydrocephalus. Intracranial pressure, B-wave and clinical analysis in patients with noncommunicating and communicating hydrocephalus
Sammanfattning : Aims of present investigations. Adult patients with clinical and radiological findings consistent with normal pressure hydrocephalus (NPH) were studied. LÄS MER
3. Invasive treatment of renal artery stenosis - effects on blood pressure, medication, renal function and inflammatory biomarkers
Sammanfattning : Renal artery stenosis (RAS) causes hypertension, decreased glomerular filteration rate (GFR), and renal ischemia. RAS is progressive and causes 5-16% of all cases of renal failure. Prevalence of RAS in patients with hypertension is 1-5%. LÄS MER
4. Studies on adverse-pressure-gradient turbulent boundary layers on wings
Sammanfattning : The present licentiate thesis addresses the use of well-resolved simulations to simulate turbulent boundary layers (TBL) subjected to adverse pressure gradients. Within the thesis a wide variety of analyses are performed, and a method to improve the performance of the simulations is presented. LÄS MER
5. Experimental studies in jet flows and zero pressure-gradient turbulent boundary layers
Sammanfattning : This thesis deals with the description and development of two classical turbulent shear flows, namely free jet and flat plate turbulent boundary layer flows. In both cases new experimental data has been obtained and in the latter case comparisons are also made with data obtained from data bases, both of experimental and numerical origin. LÄS MER
