1. Pulsed Electric Field Food Treatment and Low Frequency Bioelectromagnetics
Sammanfattning : This thesis is divided in two parts, both of which address the interaction between biological cells (especially cell membranes) and electromagnetic fields. The first part deals with the application of intense pulsed electric fields (PEF) in foods. It is intended to be a non-thermal method to inactivate microorganisms. LÄS MER
2. Effects of Pulsed Electric Fields on Plant Tissue
Sammanfattning : The interaction between biological cells and external electric fields has been of interest by scientists for several decades. Exposure of the cells to electric fields leads to various kinds of biophysical and biochemical responses. These responses can be used to characterize cell properties and/or to manipulate cell characteristics. LÄS MER
3. Inactivation, Cell Injury and Growth of Microorganisms Exposed to Pulsed Electric Fields Using a Continuous Process
Sammanfattning : Pulsed electric fields (PEF) is a proven technology to inactivate microorganisms under non-thermal conditions. The PEF technology has a potential as a "quality friendly" alternative to traditional methods of food preservation. LÄS MER
4. Effects of ionising and non-ionising radiation in cell systems and a rat model for immuno-therapy
Sammanfattning : The most malignant brain tumour, glioblastoma multiforme (GBM), has an utterly bad prognosis. In spite of all available therapy, the mean survival time is less than a year. In the unique BRIGTT project (Brain Immuno Gene Tumour Therapy), patients at the Dept of Neurosurgery. LÄS MER
5. Metal fusion using pulsed GasMetal Arc : Melt pool modellingand CFD simulation
Sammanfattning : Pulsed gas metal arc is a highly efficient technique used in manufacturing processes like welding and additive manufacturing. It offers high productivity and cost benefits but it is also prone to defect formation when process parameters are not properly controlled and optimized. LÄS MER
