A vibronic exciton model is applied to explain the long-lived oscillatory features in the two-dimensional (2D) electronic spectra of the Fenna-Matthews-Olson (FMO) complex. Using experimentally determined parameters and uncorrelated site energy fluctuations, the model predicts oscillations with dephasing times of 1.3 ps at 77 K, which is in a good agreement with the experimental results. These lon

Background: Pro-inflammatory cytokines can affect intracellular lipid metabolism. A variety of effects have been described for different cell types; hepatocyte lipid turnover pathways are inhibited during inflammation, whereas interleukin-1 beta (IL-1 beta) reduces intracellular cholesterol levels in fibroblasts. Levels of the pro-inflammatory cytokines IL-1 beta and tumour necrosis factor-alpha (

Water-soluble chlorophyll-binding proteins (WSCPs) are interesting model systems for the study of pigment-pigment and pigment-protein interactions. While class IIa WSCP has been extensively studied by spectroscopic and theoretical methods, a comprehensive spectroscopic study of class IIb WSCP was lacking so far despite the fact that its structure was determined by X-ray crystallography. In this pa

The present study is a comparative analysis of the effects of the Open Method of Coordination (OMC) through the i2010 eGovernment Action Plan on two categories of EU member states: leaders and laggers, the latter of which has been divided into two categories. It examines the development of eGovernment within the categories mentioned above based on the EU‟s annual eGovernment benchmark reports. Fur

In 2001 the Doha Round Talks was initiated by the World Trade Organization. Development was the overarching goal. For several developing countries with a comparative advantage in agriculture, trade with such products is seen as essential to economic growth and thus development. In order to spur this development it appears to be particularly important that developing countries have increased access

This thesis investigates the Designated Operational Entities (DOEs) under the Clean Development Mechanism (CDM) of the Kyoto Protocol. The DOEs serves as independent third-party auditors with the task of validating, verifying and certifying projects under the CDM. The majority of the DOEs are private entities. This is in line with the CDM objective of including the private sector in the climate ch

The role of Non-Governmental Organizations (NGOs) in world politics in general, and in the United Nations (UN) in particular, is increasingly gaining the attention by scholars of international law, political science and social anthropology. In this study the NGO-UN relation is investigated within the area of Human Rights. This is done by examining how NGOs are perceived by member states within the

The aim of my study is to critically analyse the discourse behind two different integration projects in Sweden, by using post colonial theory. My hypothesis is that many projects intended for increased integration includes a view of immigrants as the ?Others? which can be seen in how one talks about integration and culture in the discourse behind integration projects. The first of these two proje

The purpose of this work is to map what inspiration means to people who work with music, how it feels when you are inspirated compared to how it feels when you`re not. How does inspiration affect us? Are we depending on it? What do you do when you lack inspiration? Is it possible to ?inspire? one self? My method has been to interview eight persons, selected by me, who all work with music. I have u

This study of pro-poor solid waste management (conducted in Manila 2006) look at waste both as a health problem and as a livelihood for the poor. Pro-poor solid waste management policies optimize social- environmental- and economic benefits for the poor. In practice, this mean creating job-security for informal waste-pickers (scavengers), establish subsidies to community based recycling schemes an

This thesis aims to examine how the electoral system affects the behaviour of the political elites in an African context. My hypothesis is that different electoral system presents different incentives to political elites and that these incentives affect their behaviour, contributing to the formation of a specific political culture, more or less beneficial for the consolidation of democracy. The st

The electronic structure and the highest occupied molecular orbitals (HOMO)/the lowest unoccupied molecular orbitals (LUMO) alignment at the molecular semiconductor heterointerface of nanostructured TiO2/ZnPcGly dye sensitizer were characterized by X-ray and ultraviolet photoemission spectroscopy (XPS and UPS). The HOMO level of the dye ZnPcGly was determined to be located at 1.62 eV below the Fer

Photoinduced electron injection from the sensitizer Ru(dcbpy)2(NCS)2 (RuN3) into SnO2 and TiO2 nanocrystalline films occurs by two distinct channels on the femto- and picosecond time scales. The faster electron injection into the conduction band of the different semiconductors originates from the initially excited singlet state of RuN3, and occurs in competition with intersystem crossing. The rate

Excited-state dynamics and solvent-solute interactions of 1,1'-diethyl-2,2'-cyanine iodine (1122C) in alcoholic solutions are investigated using time-integrated three-pulse photon-echo spectroscopy. 1122C serves as a model compound for ultrafast photoinduced isomerizationa key process in the light reception of plants, bacteria, and human vision. The photoreaction in 1122C is interrogated in depend

Self-assembling of a carotenoid and pheophytin a into a supramolecular system was observed on the surface of nanocrystalline TiO2, and the photoinduced electron-transfer reactions within the system were studied by means of femtosecond transient absorption and laser flash photolysis techniques. Excitation of the pheophytin moiety results in ultrafast electron transfer from carotenoid to the excited
