The effects of ionizing radiation in different compositions of polymer gel dosimeters are investigated using FT-Raman spectroscopy and NMR T2 relaxation times. The dosimeters are manufactured from different concentrations of comonomers (acrylamide and N,N'-methylene-bis-acrylamide) dispersed in different concentrations of an aqueous gelatin matrix. Results are analysed using a model of fast exchan
C3 and C5 convertases are central stages of the complement cascade since they converge the different initiation pathways, augment complement activation by an amplification loop and lead to a common terminal pathway resulting in the formation of the membrane attack complex. Several complement inhibitors attenuate convertase formation and/or accelerate dissociation of convertase complexes. Functiona
The following thesis is examining compliance with EU-law from a member state perspective. The variation in the compliance level between the member states from 1995 to 2005 is analyzed to prove the fact that the Nordic member countries during the measured time period experienced a low number of infringements. The infringements that did occur were resolved faster and more efficient in the Nordic cou
We present the results of dynamic in-situ 3D X-ray imaging of methane hydrates microstructure during methane hydrate formation and dissociation in sand samples. Short scanning times and high resolution provided by synchrotron X-rays allowed for better understanding of water movement and different types of gas-hydrate formation. Complementing previous observations, we conclude that the process of g
Hidden Markov models are applied in many expert and intelligent systems to detect an underlying sequence of persistent states. When the model is misspecified or misestimated, however, it often leads to unrealistically rapid switching dynamics. To address this issue, we propose a novel estimation approach based on clustering temporal features while penalizing jumps. We compare the approach to spect
Although the two active redox centers in Li-rich cathodes, including the anionic and cationic contributions, can enable Li-ion batteries to achieve outstanding specific energy, their behaviors at different current densities have not been clarified. Here, we provide a comparative study of transition metals (TMs) and oxygen redox activities by directly accessing their oxidation states in Li-rich mat
The TRE3 research project focuses on the development of a new and innovative timber frame wall modulus for emergency housing facilities. The wall modulus, in this paper referred to as Hybrid Timber Frame (HTF) wall system, is an evolution of the traditional Light-Frame Timber (LFT) structural systems and combines the advantages and some peculiar aspects of lightweight structures to the potentialit
The chiral bile salt sodium cholate has been covalently linked to tetra-aryl-porphyrins, conferring them an extrinsic chirality and obtaining new molecules with high tendency to aggregate in solution. The chirality transfer from the molecular to the nano- and meso-scale has been investigated by promoting the self-assembly of the conjugates balancing the ratio of aqueous/organic solvent mixtures an
Since the introduction of the co-decision procedure in the European Union (EU), the Council of the EU and the European Parliament have become more interdependent in order to reach an agreement on a legislative file. The interdependence has led to a significant increase in the number of trilogues, which is problematic as these informal meetings are secluded and have no references to the treaties. D
This bachelor’s thesis explores assimilation of low-code technologies post-adoption within organisations. Through a qualitative approach involving nine semi-structured interviews, which were analysed thematically and discussed with resource-based theory, two distinct uses of low-code technologies are identified: as a technical facilitator for fast and cost-effective software development, and as a
Med elasticitetsteori kan man inte beskriva hur en statiskt obestämd konstruktion där materialet kan plasticeras går till brott. Enligt elasticitetsteori och ett antagande om ett sprött brott vid en viss spänning går en konstruktion till brott så fort denna spänning uppnås i det högst belastade snittet. Det som egentligen sker är att materialet plasticeras vilket leder till en momentomlagring. KonUsing theory of elasticity it is not possible to describe exactly how a statically indeterminate structure collapses. Theory of elasticity is often combined with an assumption of breakage at a certain level of stress, this meaning that a structure will break as soon as this level of stress is reached in the most heavily loaded section. A plastic hinge will occur followed by a changed distribution
Tillgång till tillräckliga mängder vatten av god kvalitet är en väsentlig resurs för samhället. Det behövs för mänsklig konsumtion, för produktion i industrin, för fisket, etcetera. Det är därför mycket oroande att vattenkvaliteten i Europeiska unionen successivt försämras. Östersjön som är mycket påverkad av övergödning kan nämnas som ett exempel. Övergödning orsakas av utsläpp av näringsämnen iThe supply of good quality water is an essential resource for society. It is needed for human consumption, for production processes in the industry, for fishing, etcetera. The fact that the quality of waters within the European Union is continuously deteriorating is therefore of major concern. One example is the Baltic Sea, which is heavily affected by eutrophication. Eutrophication is caused b
Through this degree project, we have come up with effective methods in the computer program ArchiCAD that architects use during project planning for buildings. The purpose of the degree project was to examine how architects and software developers use ArchiCAD effectively, in the building process so that also information transfer to other actors works. The theory of the degree project deals with t
This paper is arguing that China’s political and economic opening in 1978, also referred to as China’s open door policy, was initiated by a change within China’s institutions affecting the political as well as the economic system. Since the opening in 1978 up until today (2012), constant economic reforms and developments as well as political progress can be observed. Domestic examples of China’s p
Disposable hygiene products, such as gloves and aprons, are commonly and frequently used in healthcare environments and are essential to maintain the hygiene standard. They are placed in different types of carriers, primarily in examination rooms and are mounted on the walls. This creates some difficulties for product development and fast access because not all hygiene products fit all carriers an
The aim of this thesis has been to analyse what kind of explanations that is presented in earlier research to why drug addicts get to the end of their drugabuse. The questions that our work came out of has been: 1. What external factors mean something for a drugaddict to end his or her drugabuse? 2. What internal factors mean something for at drugaddict to end his or her drugabuse? 3. Of what impo
A novel flamelet-generated manifold (FGM) model is introduced, encompassing ignition and flame propagation in ammonia/n-heptane dual-fuel combustion under reactivity-controlled compression ignition (RCCI) engine conditions. To generate the FGM mapping function (FGM tabulation) accounting for multiple combustion modes in RCCI combustion, a novel one-dimensional RCCI configuration (1D-RC) is propose
