Proton-exchange membrane fuel cells (PEMFC)s are increasingly regarded as promising environmentally benign power sources. Intensive development is today directed towards reducing the cost and increasing the durability of the fuel cell, as well as expanding the operational window for the PEMFC for a range of applications. The proton-conducting membrane is one of the key components in the PEMFC. The

The electroactive polymer materials considered in this work react to electric stimuli by producing deformations. In some cases, the electrically induced deformations are moderate, while in other cases they can be very large and the specimen is stretched to more than twice its original length. The latter response is seen in so called dielectric elastomer actuators (DEA). The possibility of very lar

Analysis of PCR/RFLP variation in 57 Nordic populations of the herb Silene dioica, revealed 13 composite chloroplast DNA (cpDNA) haplotypes. The geographic distribution of the haplotypes suggests that the postglacial colonization of Fennoscandia by S. dioica may have involved immigration of populations from two main directions. The commonest cpDNA haplotype dominates in populations throughout most

The reaction dynamics of several polyatomic systems have been investigated in solution by femtosecond spectroscopy. Tetranitromethane-naphtalene complexes excited in the charge-transfer band at 400 nm undergo dissociative electron transfer, resulting in three primary products: [naphthalene].+, NO2 and C(NO2)3-. It was shown that this triad is formed within 200 fs. The subsequent competing reaction

The spread of lifestyle-related diseases has become epidemic throughout the world. Impaired glucose metabolism and high levels of plasma cholesterol are risk factors for the development of type 2 diabetes and cardiovascular disease respectively. Soluble dietary fibers from plants, algae and mushrooms have been shown to positively regulate both glucose- and cholesterol metabolism indicating their v

This thesis describes the structure and interactions of a novel extracellular matrix protein - PRELP (proline arginine-rich end leucine-rich repeat protein). The amino acid sequence of PRELP showed that it belonged to the leucine-rich repeat (LRR) protein family in connective tissues. The main part of PRELP is composed of 10 LRRs flanked by disulfide bridges at the amino- and carboxy-terminal end

In order to deliver optimal paediatric care, we need to know what children and their parents need, expect, and experience. Thus, the general aim of the studies upon which this thesis is based was to elucidate different aspects of parental participation in the care of their child during hospitalisation for paediatric surgery, a specific aim being formulated for each of the four studies. The aim of

In this work the lateral heterogeneity of the thylakoid membrane was investigated by quantifying the amount of photosystem I (PSI), photosystem II (PSII) and some PSII complexes and PSII proteins in different domains of the thylakoid. Grana, grana core, grana margins and stroma lamellae + end fractions were obtained by sonication and separation in a non-detergent, aqueous polymer two-phase system

The aim of this thesis was to use cosmogenic exposure dating to investigating whether highly weathered landscapes in the Northeast Greenland fjord zone have developed during prolonged ice free conditions or have been preserved beneath cold-based ice. Previous work along the Northeast Greenland coast has presented two conflicting hypotheses for the extent of the Greenland Ice Sheet during the last

Sweden has never before had so many serving life sentences. Anyone sentenced to life imprisonment has the opportunity to apply to have their sentence fixed by a court. In that examination, the court must take into account various factors, including whether there is a risk that the lifer will relapse into serious crime. To help answer that question, the court has a statement from the National Board
