Sammanfattning : Recent studies have shown that nanoparticles may be more toxic than larger particles of the same material, but the health risks associated with widespread use largely depend on the extent of exposure. When dealing with potentially toxic particles, precautionary measures have to be taken in order to minimize contact. LÄS MER
2. Microdialysis Sampling of Macro Molecules : Fluid Characteristics, Extraction Efficiency and Enhanced Performance
Sammanfattning : In this thesis, fluid characteristics and sampling efficiency of high molecular weight cut-off microdialysis are presented, with the aim of improving the understanding of microdialysis sampling mechanisms and its performance regarding extraction efficiency of biological fluid and biomarkers.Microdialysis is a well-established clinical sampling tool for monitoring small biomarkers such as lactate and glucose.

Sammanfattning : Cavitation is a problem in many hydroelectric power plants since it can cause adverse effects on performance and damage to nearby solid surfaces. The concerns of this thesis are the numerical aspects of flow simulations in cavitating hydraulic turbines which contain several difficulties: turbulent and complex flows, steady and moving parts of the geometry, bubble transport and cavitation development.

Sammanfattning : The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. LÄS MER
5. Modeling Flow and Solute Transport in Packed Beds : Applications in On-site Wastewater Treatment Systems
Sammanfattning : The use of separate phosphorus (P) filter units containing replaceable filter materials with a high P binding capacity have been suggested as an appropriate passive method to treat the P from pre-treated domestic wastewater in on-site facilities. A large number of materials have been identified and suggested as being potentially suitable for such filters. LÄS MER
