Popular Abstract in Swedish Syfte: Att studera de inter- och intramolekylära processer som sker efter excitation av en porfyrinmolekyl. De huvudsakliga pigmenten i det fotosyntetiska antennsystemet; klorofyll a, klorofyll b, samt bakterioklorofyll a är alla porfyriner, som absorberar solljus och transporterar energin till ett reaktionscenter där energin används för laddningsseparation och elektroThis thesis describes inter and intramolecular dynamics in porphyrin molecules. To create a basis for understanding the energy and electron transfer processes in photosynthesis, the ultrafast dynamics of monomeric chlorophyll a, chlorophyll b and bacteriochlorophyll a were studied with ultrashort laser pulses. The transient absorption spectra of all three molecules were found to have pronounced co

In recent years two new finds of miniature weapons and tools have been made on the Iron Age site of Uppåkra. Because of this it is my intention to present an alternative interpretation that might perhaps supplement earlier studies of these objects. The idea came to me while reading about the Iron Age woman being adopted into her husband 's family in connection with the wedding and the rituals link

Dietary factors have been reported to affect the development of spontaneous diabetes in various colonies of inbred and outbred diabetes-prone (DP) BioBreeding (BB) rats. Several studies have attributed a protective effect to a diet omitting crude protein mixtures in favor of purified casein, hydrolyzed casein, or free amino acids. We have used inbred BB rats, all of which become diabetic in specif

Many combinatorial optimization problems lend themselves to be modeled as distributed constraint optimization problems (DisCOP). Problems such as job shop scheduling have an intuitive matching between agents and machines. In distributed constraint problems, agents control variables and are connected via constraints. We have equipped these agents with a full constraint solver. This makes it possibl

Despite the importance of canon law in the life of the Eastern Orthodox Churches, there has not been a study of the ecclesiology of the canons regulating marriage. Marriage is an object of right regulated both by civil law and the canon law of the Eastern Orthodox Church. Marriage as an object of right is at the intersection of two legal orders - the ecclesial and the civil. The canonical regulati

The thesis deals with ritual remembrance ceremonies enacted in the three towns of Mostar, Jajce and Višegrad in BiH. The Old Bridge in Mostar, the Bridge over the Drina in Višegrad and the AVNOJ Museum in Jajce all carry a material presence that influences everyday life in these localities. Through ethnographic fieldwork, insights into local practices in relation to those World Heritage Sites are

Objective: To investigate whether tandem gait test (TG) can predict future falls and/or near falls in people with Parkinson’s disease (PD). Background: People with PD have balance problems and an increased risk for falls. Although TG has been considered a predictor of falls, no PD-study has controlled results for demographic and disease-specific characteristics or included near falls when investig

In the early 1990s, Indonesia was seen as one of the post war success stories. The country was boasting an impressive growth record and had seen the number of poor continuously decline. This picture of Indonesia stood in stark contrast to the situation only 30 years earlier when the economy was in a shambles and starvation was a real threat. At the core of this change in Indonesia lies the transfo
