1. Slow and stopped light by light-matter coherence control
Sammanfattning : In this thesis we study light-matter coherence phenomena related to the interaction of a coherent laser field and the so-called Λ-system, a three-level quantum system (e.g., an atom). We observe electromagnetically induced transparency (EIT), slow and stored light in hot rubidium vapor. LÄS MER
2. Pulsed Electric Field Treatment of Plant Tissue
Sammanfattning : A pulsed electric field (PEF) is a newly emerged non-thermal food processing technology which has characteristic effects on the cell membrane. PEF processing involves subjecting food to short, repeated pulses of a high electric field between an anode and a cathode. LÄS MER
3. Characterizations of ground flashes from tropic to northern region
Sammanfattning : This thesis portrays new information concerning the cloud-to-ground (CG) lightning flashes or ground flashes produced by thunderclouds. It emphasizes the importance of characterizing lightning studies as the relationship between lightning mechanisms, and of incorporating the influence of geographical location, latitude and storm type.

4. TINT Tumor Indicating Normal Tissue : new field of diagnostic biomarkers for prostate cancer
Sammanfattning : Background: Prostate cancer is the most common cancer in Sweden. Due its highly variable behavior, multifocal nature, and insufficient diagnostic methods, prostate cancer is difficult to diagnose and prognosticate. LÄS MER
5. Geochemical modelling of acid mine drainage in mill tailings : Quantification of kinetic processes from laboratory to field scale
Sammanfattning : Assessment of the potentially acidic, heavy metal-ladenleachates that leave deposits of sulfide ore mill tailings andevaluation of various possible options for mill tailingremediation are scientific problems of increasing practicalimportance. High costs may be associated with the mill tailingremediation, not least after recent changes in Swedish andEuropean environmental legislation. LÄS MER
