Ultrafast Dynamics in Ground and Excited States of Porphyrin Molecules

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

Miniatyren : ingen småsak. En presentation av en alternativ tolkning till vapen- och redskapsminiatyrer i Uppåkra.

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

Protein-free diets do not protect high-incidence diabetes-prone BioBreeding rats from diabetes.

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

Distributed constraint programming with agents

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

Marriage as the Arena of Salvation : An Ecclesiological Study of the Marital Regulation in the Canons of the Council in Trullo

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

Tre städer, två broar och ett museum : minne, politik och världsarv i Bosnien och Hercegovina

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
