1. Molecular Quadratic Response Properties with Inclusion of Relativity
Sammanfattning : This thesis concerns quadratic response properties and their application to properties in Jablonski diagrams such as resonant two-photon absorption and excited state absorption. Our main interest lies in optical power limiting applications, and in this context, molecules containing heavy metal atoms prove superior. LÄS MER
2. Light Control using Organometallic Chromophores
Sammanfattning : The interaction between light and organometallic chromophores has been investigated theoretically in a strive for fast optical filters. The main emphasis is on two-photon absorption and excited state absorption as illustrated in the Jablonski diagram. We stress the need for relativistic calculations and have developed methods to address this issue. LÄS MER
3. Carotid Artery Stenosis : Surgical Aspects
Sammanfattning : Randomised controlled trials (RCT) have demonstrated a net benefit of carotid endarterectomy (CEA) in stroke prevention for patients with severe carotid artery stenosis as compared to best medical treatment. Results in routine clinical practice must not be inferior to those in the RCTs. LÄS MER
4. Development of characterisation methods for the components of the polymer electrolyte fuel cell
Sammanfattning : In this work characterisation methods and fuel cell hardwarewere developed for studying the components of the polymerelectrolyte fuel cell (PEFC). Humidifiers and other componentswere tested in order to develop reproducible and reliableexperimental techniques. A set-up for testing larger cells andstacks was developed. LÄS MER
5. The sites and mechanisms of postoperative insulin resistance
Sammanfattning : In Sweden with nine million inhabitants, 450,000 operations (outpatients excluded) are performed every year resulting in 2,250,000 treatment days in hospital. Surgical operations are part of the treatment for 44% of all patients admitted to hospital care occupying 24% of all hospital beds. LÄS MER
