This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying

The main concern of this paper is the joint utilization of new methods of research and analysis in the study of value. 40 persons, varying from age 20 to 70 and from different professional domains were studies by the use of a three-images technique inspired by Murray´s TAT. The aim was to unveil the implicit dimensions of work related values. Three analytical methods (content analysis, lexical ana

The findings from a user study regarding particular ob- servable “interaction patterns” in the interaction during a “guided tour” are summarized in this paper.

Vision sensors are of increasing interest for non-intrusive, remote measurements in industrial as well as consumer products. Their operation is based on intelligent techniques for image understanding, followed by robust quantification of the detected phenomenon. A well-known application area is movement detection and isolation. This paper discusses how movement can be detected and quantified by me

The protein folding problem is addressed focussing on the hydro- phobicity patterns in the amino acid sequences and structures. Both real and model proteins are investigated. The hydrophobicity pattern of real proteins is probed in two ways. First, it is asked which binary pattern is most conserved within groups of related proteins. Not unexpectedly, the most conserved patterns are strongly corre

By tradition, comparisons between first and second language acquisition involve data from child or adult L2 learners and data from young L1 children. However, there is a subgroup of L1 children, namely children with Specific Language Impairment (SLI), which is rarely accounted for in these comparisons. These are children with significant problems in acquiring their mother tongue despite growing up

Popular Abstract in Swedish Sammanfattning Nukleotider påverkar kärltensionen och hjärtats slagkraft. Då ett blodkärl skadas, då blod koagulerar eller vid minskad syretillförsel till hjärtat frisätts en mängd ämnen från kärlväggar och blodceller. Bland annat frisätts så kallade nukleotider (ATP, ADP, UTP och UDP). Nukleotider har tidigare visats ha viktiga funktioner inuti cellen vid energiomsättnThe aim of the thesis was to examine the expression and function of the extracellular nucleotide P2 receptors in the cardiovascular system. In the cardiovascular system nucleotides are released during shear stress, hypoxia, ischemia, from endothelial cells, smooth muscle cells, aggregating platelets, inflammatory cells and erythrocytes. We demonstrate that ATP, ADP, UTP and UDP induce vascular rel

The use of systems analysis involving tools like Causal loop diagrams and stock and flow diagrams can be shown in practical tests to greatly enhance systems insight and understanding of the dynamic behaviour of complex systems. Whereas many students may have difficulty understanding what a coupled system of differential equations really do, systems analysis creates such insights even to those with

Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climate is, however, being questioned. Therefore more and more of these buildings are being built with double skin facades, which can provide: a thermal buffer zone, energy savings, wind protection with open windows, fire protection, aesthetics, solar preheating of ventilation air, sound protection, polluta
