This thesis presents the utilization of electroanalytical methods for analysis of dynamic cellular processes such as exocytosis, intracellular redox reactions and cell surface interactions. Microchips have been designed and manufactured with the purpose of monitoring dopamine exocytosis from single or a small ensemble of PC12 cells. The electrode surface was modified with self assembled monolayers
Popular Abstract in Swedish Utvecklingen av offentlig sektor har de senaste årtiondena till stor del påverkats av New Public Management. Som en konsekvens av detta har en ”marknadisering” av offentliga verksamheter och organisationer skett. Denna ”marknadisering” har resulterat i att det finns organisationer i offentlig sektor som varken passar in på beskrivningen av offentliga organisationer elleDuring the last decades the influence of New Public Management and the “marketisation” of public services, have given us organisations in the public sector that fit neither the mould of what constitutes public sector organisations nor that of private companies. Instead, we now have so-called hybrid organisations. These have become an attractive alternative to the more “bureaucratic” public agencie
Popular Abstract in Swedish I detta projekt studerar vi reaktioner som är av betydelse för omvandling av ljusenergi till elektricitet eller bränsle. Materialen är nya typer av organiska polymermaterial som kan ge morgondagens energisnåla och miljövänliga solceller, TV- och datorskärmar, ljuskällor, mm. Men för att detta skall inträffa krävs mycken ny forskning för att förstå de processer som liggeThe main part of the thesis is concerned with charge photogeneration in conjugated polymers. MeLPPP and POMeOPT films were investigated by transient absorption spectroscopy using different excitation photon energies and light intensities with and without an external electric field. We conclude that electric field-assisted charge pair photogeneration occurs from vibrationally relaxed singlet excito
The arch dam at Selsforsen and the buttress dam at Storfinnforsen are two concrete dams of which both have suffered from severe surface spalling on the upstream face, far below the full water supply level. A hypothesis is that macroscopic ice lens growth, similar to frost heave in soil, could have occurred within the dam walls. After initial deterioration of the concrete dams by frost damage or cr

Iterative learning control (ILC) is used as a means for task execution of a time sub-optimal trajectory. The use of cascaded ILC procedures in a robot application is experimentally shown to drastically enlarge the region of convergence and efficiently compensate for unmodeled dynamics in the motion system. Objectives considered are the duration of motion, maximum liquid slosh during the motion, an
Logistics is being given increased attention in companies and in research, and is gaining strategic importance as supply chains or, more aptly named, supply networks are the realm of today. For both researchers and practitioners in the field of logistics one of the fundamental concepts is the systems approach. As many researchers proclaim, to understand logistics you need to understand the concept
During the last decades of the 1900’s, businesses started to - in a broader sense than before - acknowledge the economic relevance of intangible components, such as emotional experiences, of products and services. This dissertation explores how the so-called lifestyle hotel segment reflects the socio-cultural currents that set the conditions for these changes in the Western economy. The aim of the
Popular Abstract in Swedish Syftet med den här avhandlingen har varit att med hjälp av datorsimuleringar studera laddade polymerers (polyelektrolyters) växelverkan med motsatt laddade sfäriska makrojoner. Redan nu kan en icke kemikunnig person bli helt borttappad, ty: 1. Vad är en polymer? 2. Vad är en sfärisk makrojon? 3. Växelverkan mellan polymer och makrojon? 4. Datorsimuleringar? 5. Vad är dPolyelectrolytes are polymers bearing ionisable groups, which, in polar solvents, can dissociate into charged polymer chains (polyelectrolytes) and small counterions. In aqueous solutions, polyelectrolytes interact strongly with other macroions and in particular they tend to associate with objects of opposite charge and form complexes. Nearly all industrial and biological process involves solution
In Scandinavian, nominal phrases can contain constituents that look like possessors without having a possessor theta role. These constituents, which I call pseudopossessors, come in three types: swearword pseudopossessors, measure pseudopossessors, and characterising pseudopossessors. I argue in this paper that pseudopossessors are -s-marked constituents that are located in the adjectival field in
The objective of this paper is to make a comparative analysis of the implementation of five public policy instruments directed to the industry sector, which have in common the aim to promote an increased energy efficiency. The empirical material for the paper comes from ex-post evaluations of the policy instruments carried out within the EU-project AID-EE (Active Implementation of the European Dir
In order to prevent or modify the processes of bone degeneration the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. The change in the chemical environment may consist of changes in the concent

We propose a distributed learning algorithm for fair scheduling in common-pool games. Common-pool games are strategic-form games where multiple agents compete over utilizing a limited common resource. A characteristic example is the medium access control problem in wireless communications, where multiple users need to decide how to share a single communication channel so that there are no collisio
