Fabrication of Low-Dimensional Structures in III-V Semiconductors

The thesis presents studies on the processing technology and the characterization of nanometer-sized and low-dimensional structures in III-V semiconductors. Two major approaches are described: 1) the combination of aerosol technology and plasma etching for the fabrication of quantum dots (QDs) in InP-based materials and 2) the use of high-resolution electron beam lithography and plasma or wet che

Uthålliga VA-system - internationella erfarenheter av organisationsformer och drivkrafter i en VA-sektor i utveckling

The report describes and analysis the water and sewerage system in five European countries from a resource based view I denna rapport intresserar vi oss för begreppet ’uthållighet’ (sustainability) inom ramen för vatten- och avloppsverksamheter. Utgångspunkten är emellertid varken teknisk eller ekologisk utan denna studie görs utifrån ett strategi- och organisationsperspektiv. Ambitionen är att t

Changes in bone mass and skeletal structure in the postmenopausal period.

Popular Abstract in Swedish Benskörhet (osteoporos) är en sjukdom som karaktäriseras av minskad mängd benmassa och försämrad benkvalitet. Benskörhet leder till en ökad risk för frakturer. Förekomsten av benskörhet har fördubblats under de senaste decennierna. Upp till en tiondel av alla män och en fjärdedel av alla kvinnor lider av sjukdomen. Ökningen av benskörhet i samhället kan delvis förklarasThe aim of this thesis was to evaluate long-term changes in bone mass and skeletal structure in the forearm in the peri- and postmenopausal period. 156 premenopausal women, at baseline aged 48 years, not taking medications and without disease processes known to interfere with bone metabolism, were followed through menopause by measurements of bone mass and skeletal structure at the cortical site o

Catalytic combustion in environmental protection and energy production

Catalytic combustion is an important area of catalysis and is used in energy production as well as in the abatement of harmful emissions of various types. This thesis is focused on three different areas of catalytic combustion: - Catalytic combustion of diesel soot - Development of catalytically active wire meshes through thermal spraying - Stabilisation and activation of g-alumina for methane com

Experiencing the University Context

Our problem is how to design, with the use of distance and ICT, an appropriate academic context for learning, for students with no previous knowledge of this context. Our aim is to analyse and describe the learner’s relation to the object of his/her studies as part of his/her relation to the learning activity. By using a combination of a phenomenographic approach and activity system theory, we ana

Reacting Boundary Layers in Homogeneous Charge Compression Ignition (HCCI) Engine

An experimental and computational study of the nearwall combustion in a Homogeneous Charge Compression Ignition (HCCI) engine has been conducted by applying laser based diagnostic techniques in combination with numerical modeling. Our major intent was to characterize the combustion in the velocity- and thermal boundary layers. The progress of the combustion was studied by using fuel tracer LIF, th

Psykodynamisk korttidsterapi : En intensivstudie av samspel, förändring och utfall

Popular Abstract in Swedish Psykoterapi betraktas idag som en etablerad behandlingsform för människor med psykiska problem. Under senare hälften av 1900-talet växte intresset för alternativa behandlingsformer inom vårdsektorn, och en ansenlig mängd psykoterapeutiska metoder utvecklades. Under denna period tog även psykoterapiforskningen fart, med syfte att undersöka vilken betydelse olika behandliThe overall aim of the thesis was to investigate the effects of psychodynamically oriented psychotherapy and gain an increased understanding of the curative factors in psychotherapy by thorough examination of the therapeutic alliance and of client change. The core of the thesis is a naturalistic study of 22 short-term dynamic psychotherapies and a follow-up 6-12 months later. Individual outcome me

The Nobel Prize: A 'Heritage based' Brand-oriented Network

Purpose – Understanding the Nobel Prize as a ‘true’ heritage brand in a networked situation and its management challenges, especially regarding identity and reputation.Methodology – The Nobel Prize serves as an in-depth case study and is analysed within an extended corporate brand identity framework that incorporates reputation.Findings – The Nobel Prize is a ‘true’ corporate heritage brand (in th

Competitive adsorption of macromolecules during emulsification

The adsorption behavior of macromolecular emulsifiers is important in the understanding of their functionality. Understanding of the adsorption behavior can ultimately enable us to control emulsion properties. Adsorption during emulsification differs from many adsorption processes as the interface at which adsorption occurs is created in parallel with the adsorption. In this thesis two different m

Excited State Processes in Solar Energy Materials

Popular Abstract in Swedish Den globala energianvändningen är idag större än någonsin. Faktum är att den, i takt med världens ständiga utveckling, kommer att fortsätta öka många år framöver. Sättet som energi har producerats på historiskt används dessutom i allra högsta grad fortfarande idag och innebär daglig förbränning av stora mängder organiskt material. Detta resulterar i en ökad koncentratioThis dissertation covers studies of excited state processes in two types of solar energy materials: alternating polyfluorene polymers and their blends with fullerenes in the active layer of plastic solar cells, and bis-tridentate RuII-polypyridyl complexes to be used as sensitizer in systems for artificial photosynthesis. The polymer:fullerene blends were studied by transient absorption and time-
