Boronate-containing thin polyacrylamide gels (B-Gel), polymer brushes (B-Brush) and chemisorbed organosilane layers (B-COSL) were prepared on the surface of glass slides and studied as substrates for carbohydrate-mediated cell adhesion. B-COSL- and B-Brush-modified glass samples exhibited multiple submicron structures densely and irregularly distributed on the glass surface, as found by scanning e
The intention of this thesis was to evaluate the effects of inflammation at very preterm birth on subsequent morbidity, as well as on the neuro-protective IGF-system. Prospective clinical studies of very preterm infants constituted a base for the evaluation. Temporal changes in levels of cytokines were chosen as markers of an induced inflammatory response and were evaluated together with component
The European Union (EU) and the United States (US) often use different foreign policy strategies. In their non-proliferation policies they have had somewhat different approaches towards the suspected proliferators. In this thesis the usefulness and effectiveness of these different strategies, containment and engagement, are studied within the question of non-proliferation of Weapons of Mass Destr
In this paper the trade of virtual items in online games for hard currency is analysed using economic theory. There are real welfare gains from trade but the game designer’s interests must be taken into account when deciding whether trade is desirable or not. Ricardo's Comparative Advantage and Hecksher-Ohlin Factor Proportion theories lead to conclusions about game design when trade is free.
Nanoteknik är ‘big business’. Stora summor pengar står på spel då detta innovativa teknikområde expanderar i snabb takt. Denna undersökning utgår från antagandet att ekonomiska intressen snarare än demokratiska värden och hållbar utveckling styr utvecklingen av nanoteknik i Sverige idag. Detta ses som problematiskt, och det övergripande målet är att föreslå alternativa principer för att styra utveNanotechnology is big business. With rapid innovation and expansion of the field, financial stakes are high. This study is based on the assumption that the development of nanotechnology in Sweden today is controlled by economic interests rather than democratic values and sustainable development. This is considered problematic, and the overall aim with this study is to propose alternative principle
A considerable part of world merchandise is transported by sea, and with about 150,000 crew members working on the ship types of interest for this thesis there is much at stake if an accident occurs, both with respect to human lives and financial losses. Since fires have previously shown to be responsible for many accidents with severe consequences, the aim of this thesis has been to investigate t
This work studies the design of linear precoder codebooks for N-r x N-t MIMO channels with MMSE detection at the receiver. A natural split of precoder-design is unitary precoding and non-unitary precoding. Unitary precoding is only performing rotation of the data in a way beneficial for the channel. Non-unitary precoding additionally also uses power-loading to further improve the performance. Some
Popular Abstract in SwedishDDR:s utrikespolitik gentemot Sverige och övriga västeuropeiska stater dominerades sedan början av 1950-talet av en strävan efter diplomatiskt erkännande. Avhandlingen undersöker denna strävan genom att analysera de östtysk-svenska relationerna från 1949 till 1972. Tyngdpunkten ligger på åren 1954-1972. Huvudsakligen har källmaterial från det i DDR styrande kommunistpartSince the early 1950’s the foreign policy of the German Democratic Republic (GDR) towards Sweden and the other Western European states was dominated by a striving for diplomatic recognition. This thesis examines that striving through an analysis of the East German-Swedish relations from 1949 until 1972. The main focus is on the years 1954-1972. The thesis draws mainly on East German archival mater
This study is based on a total cohort (N = 192) of people born in 1902 and 1903 and living in southern Sweden. Subjects were assessed at baseline when 67 years of age and on eight further occasions over 34 years or until death. The participation rate in the nine examinations ranged from 78-100%. Interviews, psychological tests, and medical examinations were used as well as information on medical d
MAIN QUESTION: To compare the diagnostic properties of Endorette and D&C in women with postmenopausal bleeding, to relate the properties to endometrial thickness as measured by ultrasound, and to assess the women's experiences of the two methods. METHODS: In a prospective study, 133 consecutive women with postmenopausal bleeding were examined with transvaginal ultrasound. After measuring the e
The aim of this work is to generate detailed and simplified kinetic models for the oxidation of the Primary Reference Fuels (PRF) n-heptane, iso-octane and their mixtures, with low numbers of species and reactions. These mechanisms are consistent in terms of the choice of kinetic parameters for the different reaction classes. The further aim is to validate the kinetic models for a wide range of di
The deficiency or abnormal function of von Willebrand factor (VWF) causes von Willebrand disease (VWD), the most frequent inherited bleeding disorder. The laboratory diagnosis of VWD can be difficult as the disease is heterogeneous and an array of assays is required to describe the phenotype. Basic classification of quantitative (type 1 and 3) and qualitative (type 2) VWD variants requires determi
The aim of this study was to compare the conventional combination of three-dimensional dosimeter (nPAG gel) and readout method (MRI) with other combinations of three-dimensional dosimeters (nPAG gel/Presage (TM)) and readout methods (optical CT scanners). In the first experiment, the dose readout of a gel irradiated with a four field-box technique was performed with both an Octopus IQ scanner and
Successful innovation strategy relies on experience gained from a complexity of understanding, anticipating and managing the global business environment. But, although much research has examined strategies of private sector organizations in Western economies, there are relatively few studies of innovation in public sector organizations of transitional and protected economic environments, such as I

The endemic mesosaurid reptiles of the Whitehill-Irati sea in southern Africa and South America during the Permian were studied with preference for the Namibian material. To date three valid mesosaurid species have been described of which two occur on both continents. These mesosaurid aquatic reptiles were among the first evidence used to support the theory of continental drift at the beginning of
Can coercive care be justified against drug and alcohol addicts or should treatment be offered on a strictly voluntary basis? This was one of the central questions debated in Sweden during the 70's when the development of a new social legislation, The Social Services Act (Socialtjänstlagen), took place. The first aim of this thesis was to analyse whether the arguments that were presented both
In 2022 and 2023, the Large Hadron Collider produced approximately two billion hadronic interactions each second from bunches of protons that collide at a rate of 40 MHz. The ATLAS trigger system is used to reduce this rate to a few kHz for recording. Selections based on hadronic jets, their energy, and event topology reduce the rate to Ô(10) kHz while maintaining high efficiencies for important s
Funktionshindrade är intresserade av att delta i samhället.
