The main theme of this thesis is the interfacial properties of cereal proteins from wheat and rye. Some aspects of dough bulk properties are also included. The proteins studied are of interest for the stabilisation of gas cells and the mechanism of gas retention, and the rheological properties of a bread dough. The interfacial properties were investigated by using methods such as film balance, el
What are Swedish children’s gestures like? How do they change over time in development? How do they relate to spoken language? Is there anything particularly Swedish about them? These questions are all discussed in this paper. The main message is that the overarching patterns of gestural development in Swedish children are similar to what has been found in studies of children in other cultures, bu

Why do Scandinavians convert to the Catholic Church? In this article, I try to give an answer to this question. Up to the Second Vatican Council in the 1960s, the Catholic Church strongly emphasised its claim to be the only true Church. As a consequence, non-Catholic countries such as the Nordic were subjected to Catholic missionary activity. In this period, a Catholic conversion was not only an e
Popular Abstract in Swedish Pankreascancer (cancer i bukspottkörteln) drabbar ungefär 900 personer om året i Sverige. Tumörformen har tidigare varit vanligare hos män men är numera lika vanlig hos män och kvinnor. Pankreascancer är ovanligt före 40 års ålder, men ökar stadigt med åldern och ungefär 80% av dem som drabbas är över 60 år gamla. Pankreascancer är en aggressiv tumörform och på grund avIn the present thesis, genetic abnormalities in pancreatic cancer were studied, with special emphasis on alterations of components involved in the transforming growth factor beta (TGFB) signaling pathway. In the first study, fluorescence in situ hybridization and cytogenetic analyses revealed aberrations of chromosome 18 in all 13 pancreatic carcinoma cell lines studied, in particular frequent bre
Our goal is to present a mathematical model useful for distributed optimization of traffic routing in multi-domain Internet networks. In such environments each domain is operated autonomously and has access to limited information about the rest of the network. Our model reflects this through an appropriate problem decomposition with respect to individual domains. The decomposition aims at supporti
A literature review and a questionnaire study with 62 participants were carried out to provide recommendations on the design of a set of evacuation systems for road tunnels: 1) Traffic Information Sign (TIS) - message and size of the sign (large or small), colour scheme, and use of pictograms and/or flashing lights, 2) Emergency exit portal layout - colour scheme, 3) Acoustic systems - voice messa
The report is a statistical analysis of how the creative class approach and specifically how technology, talent, tolerance and the creative class are linked to regional growth in Sweden. When examining the location of the creative class, technology, talent and tolerance, Uppsala, Stockholm, Gothenburg and Malmö-Lund appear as the most competitive Swedish regions. By use of multivariate regression
This study has observed and investigated random telegraph noise in the photoluminescence from InAs quantum dots in GaAs and InP quantum dots in GaInP. The dots are grown by the Stranski-Krastanow technique with a sufficiently low surface density that individual dots easily could be investigated. The luminescence from many single quantum dots, exhibiting switching between two levels, has been spect
Development and optimization of the production of lactic acid bacteria (LAB) and their attendant 'natural' inhibitors as biopreservatives to control undesirable bacteria currently remains a primary focus of several laboratories involved in research concerning food safety and quality. Strategies utilized to study incorporation of biopreservatives into food include either direct use of LAB-strains o
The advantages and disadvantages of field survey as a method for locating possible Stone and Bronze Age sites are described. Survey in the spring was favorable for finding Stone Age sites, while autumn survey was more successful for locating Bronze Age sites.
The current form-giving activity in industrial design is, by and large, characterised by explorations that depend on an individual’s capability to mentally manipulate a solution space from which to select and express the intended result. Designers often rely on artistic experimentation, aesthetic inspiration, or product specifications. Such approaches often lead to satisfactory results, but could
The work presented here aims at producing hydrogen for proton-exchange fuel-cell applications from hydrocarbons. This thesis describes an integrated catalytic converter comprising a steam-reforming reactor (heat of reaction supplied by catalytic combustion), a water-gas shift reactor and a preferential oxidation of carbon monoxide reactor, and the work performed on the fuel processing catalysts th
