Spectroscopy of the M supergiant alpha Ori in the 1-2.5 µm region

The study of elemental abundances in cool stars via atomic lines in the optical region is made difficult by stellar molecular absorption. At infrared wavelengths this problem is diminished, but ground-based observations suffer from absorption by the earth's atmosphere. Fortunately, there are spectral windows through which we can observe. We have explored several such windows in the spectral region

The Victorian Governess Novel

Popular Abstract in Swedish Ämnet för min avhandling är den viktorianska guvernantromanen. I artonhundratalets England var arbetet som guvernant ett av de få yrken som stod öppna för medelklasskvinnor. Genom att arbetsförhållandena ofta var svåra, kom den samtida debatten om guvernanternas eländiga situation att bli livlig. Den stora mängd artiklar och böcker om deras låga löner, illa definierade This thesis investigates the Victorian governess novel as a specific genre. A comprehensive set of nineteenth-century governess novels has been examined in relation to contemporary non-fictional sources dealing with governess work and female education. It is argued that by sharing many characteristics regarding presentations of social situations, rhetoric, and argument with the contemporary debate

Videokonst: omtagningar

This chapter examines contemporary Swedish video art and its relation to television, media culture, and the phenomenon of industrial image reproduction, in the perspective of the writings of Kierkegaard and Baudelaire. Works by three Swedish video artists - Andreas Hagström, Conny Blom, and Jesper Norda - are analysed.

First results from car-to-car and car-to-infrastructure radio channel measurements at 5.2GHZ

Car-to-car and car-to-infrastructure (henceforth called C2X) communications are constantly gaining importance for road-safety and other applications. In order to design efficient C2X systems, an understanding of realistic C2X propagation channels is required, but currently, only few measurements have been published. This paper presents a description of an extensive measurement campaign recently co

Photometry of Resolved Stellar Populations in Local Group Galaxies

Popular Abstract in Swedish En viktig fråga inom modern astrofysik är hur galaxer bildas och utvecklas. Under de senaste decennierna har flera teorier för hur detta sker lagts fram, vilket har lett till att de flesta astronomer idag tror på en modell i vilken större galaxer, så som vår egen Vintergata, bildas genom sammanslagning av mindre galaxer. Trots att modellen rönt stor framgång återstThis thesis presents results from two projects using photometric observations to investigate stellar populations in Local Group galaxies. In the first project, Strömgren photometry is used to study stellar populations in dwarf spheroidal galaxies. It is demonstrated that the Strömgren c1 and m1 colour indices can be efficiently used to identify RGB members in dwarf spheroidal galaxies, and d

PalCom Meets the End-User: Enabling Interaction with PalCom-based Systems

When developing applications for end-user nodes in distributed systems, it is not unusual to find that the business logic part of the solution is relatively inexpensive to develop. The resource intense parts of the solution are more likely to be those of presenting the functionality provided by the node to the end-user, and of connecting the node with the rest of the system. By considering systems

Electrochemical monitoring of living cells

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

Navigating in the landscape of ambiguity: A stakeholder approach to the governance and management of hybrid organisations

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

Energy migration and charge formation in conjugated polymers

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

Macroscopic ice lens growth : observations on Swedish concrete dams

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
