    Photo-electrochemical hydrogen production from neutral phosphate buffer and seawater using micro-structured p-Si photo-electrodes functionalized by solution-based methods2018Inngår i: Sustainable Energy and Fuels, ISSN 2398-4902, Vol. 2, nr 10, s. 2215-2223Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Solar fuels such as H2 generated from sunlight and seawater using earth-abundant materials are expected to be a crucial component of a next generation renewable energy mix. We herein report a systematic analysis of the photo-electrochemical performance of TiO2 coated, microstructured p-Si photoelectrodes (p-Si/TiO2) that were functionalized with CoOx and NiOx for H2 generation. These photocathodes were synthesized from commercial p-Si wafers employing wet chemical methods. In neutral phosphate buffer and standard 1 sun illumination, the p-Si/TiO2/NiOx photoelectrode showed a photocurrent density of 1.48 mA cm2 at zero bias (0 VRHE), which was three times and 15 times better than the photocurrent densities of p-Si/TiO2/CoOx and p-Si/TiO2, respectively. No decline in activity was observed over a five hour test period, yielding a Faradaic efficiency of 96% for H2 production. Based on the electrochemical characterizations and the high energy resolution fluorescence detected X-ray absorption near edge structure (HERFD-XANES) and emission spectroscopy measurements performed at the Ti Ka1 fluorescence line, the superior performance of the p-Si/TiO2/ NiOx photoelectrode was attributed to improved charge transfer properties induced by the NiOx coating on the protective TiO2 layer, in combination with a higher catalytic activity of NiOx for H2-evolution. Moreover, we report here an excellent photo-electrochemical performance of p-Si/TiO2/NiOx photoelectrode in corrosive artificial seawater (pH 8.4) with an unprecedented photocurrent density of 10 mA cm2 at an applied potential of 0.7 VRHE, and of 20 mA cm2 at 0.9 VRHE. The applied bias photon-to-current conversion efficiency (ABPE) at 0.7 VRHE and 10 mA cm2 was found to be 5.1%

    Språkhandlingar i flerspråkiga elevers gruppsamtal: en studie av identitetskonstruktion2018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    The aim of this thesis is to investigate how multilingual fifth-grade pupils in Sweden construct their own and each other’s identities through verbal and non-verbal discourse acts, in group discussions of diary texts without a teacher present. The group discussions were audio and video recorded by the pupils themselves and transcribed by me as a researcher.

    The theoretical foundation of this study is the social constructionist view of identities as multiple, negotiable and flexible processes which are constructed in and through interaction. This is investigated through the participants’ use of discourse acts in the form of initiatives, responses and follow-ups, drawing on the Exchange Structure Model combined with interactional tools from Conversation Analysis. The use of ESM has been expanded in the study for the investigation of non-verbal discourse acts as well. Zimmerman’s framework of the three identity dimensions discourse, situated, and transportable identities has been applied to the analysis of discourse acts, to study the pupils’ identity constructions. Their use of code-switching has been studied in connection with the third identity dimension, here the transportable identity as multilinguals.

    The results show that the pupils as a group cannot be said to make their transportable identities as multilinguals relevant to a high degree in the group discussions. However, some of the pupils make their multilingualism relevant locally, using code-switching as a resource to express feelings, to wield power, and for face-saving effects etc.

    Furthermore, reciprocal contingency between the three dimensions of identity is shown by the pupils’ identity constructions and co-constructions in the group discussions. Discourse identities like initiating diary reporter, confirmation seeker, questioner, responder and endorser are constructed at the micro level of interaction by the participants using verbal and non-verbal discourse acts. These identities build up situated identities together with existing participation frames, such as leader, ‘disser’, ‘group clown’ or reluctant. Both these identity dimensions build up transportable identities as multilinguals together with tacit background information of the participants’ language proficiency. Moreover, the results show how an expanded ESM can be used for analysing both verbal and non-verbal discourse acts and the construction of all three identity dimensions.

    Structure formation at solid/liquid interfaces: Understanding self-assembly and environmental challenges2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The work described in the present dissertation has explored the structure of particles and molecules at solid/liquid interfaces, aiming to understand the physics of self-organizing systems and use this knowledge to address some environmental issues. Surface-sensitive neutron scattering techniques, such as reflectometry and grazing incidence small angle scattering, have been used as the primary tool to investigate structures in proximity to an interface. Some of the challenges in the interpretation of neutron scattering data are discussed, and new methods for analyzing the signal have been proposed.

    It was shown that charged stabilized colloidal particles can self-assemble and form large areas (20 cm2) of crystalline structures, close to a smooth solid surface extending to depths of several micrometers, while orienting themselves into smaller crystallites in the bulk of the suspension. The adsorption of proteins from the seeds of different species of Moringa trees on alumina, silica and polystyrene surfaces was studied, as a means for using proteins from different sources and with different properties, for the water clarification step in the purification process. The seed proteins also showed to enable locking the structure of colloidal particles at the solid/liquid interface, acting as a molecular glue.

    Perfluorinated surfactants (PFASs), widely used in industrial, pharmaceutical and food packing products, have been identified as emerging pollutants, raising a global concern for the environment and wildlife. The present study has shown how PFASs molecules of different fluorocarbon chain length and with different functional groups, create defects in model membranes by partitioning and removing phospholipids from the bilayer, making the bilayer thin and less dense.

    The effect of interface roughness was studied on the lamellar structure of a non-ionic surfactant. Concentrated solutions of the surfactant have been shown to form well-ordered and well-aligned structures at a smooth interface, which could be modified further by simply heating the sample. However it was found that even small roughness, of the same order as the bilayer thickness, can distort the structure to a depth of several micrometers from the interface. Heating the sample could improve the alignment but not as much as that formed at a smooth surface.

    Non-equilibrium dynamics of exactly solvable quantum many-body systems2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Recent experimental advances on ultracold atomic gases and trapped ions have made it possible to simulate exactly solvable quantum systems of interacting particles. In particular, the feasibility of making rapid changes, so-called quantum quenches, to such set-ups has allowed experimentalists to probe non-equilibrium phenomena in closed interacting quantum systems. This, in turn, has spurred a considerable theoretical interest in quantum many-body systems out of equilibrium.

    In this thesis, we study non-equilibrium properties of quantum many-body systems in the framework of exactly solvable quantum field theory in one spatial dimension. Specific systems include interacting fermions described by the Luttinger model and effective descriptions of spin chains using conformal field theory (CFT). Special emphasis is placed on heat and charge transport, studied from the point of view of quench dynamics, and, in particular, the effects of breaking conformal symmetries on transport properties. Examples include the Luttinger model with non-local interactions, breaking Lorentz and scale invariance, and inhomogeneous CFT, which generalizes standard CFT in that the usual propagation velocity v is replaced by a function v(x) that depends smoothly on the position x, breaking translation invariance.

    The quench dynamics studied here is for quantum quenches between, in general, different smooth inhomogeneous systems. An example of this is the so-called smooth-profile protocol, in which the initial state is defined by, e.g., smooth inhomogeneous profiles of inverse temperature and chemical potential, and the time evolution is governed by a homogeneous Hamiltonian. Using this protocol, we compute exact analytical results for the full time evolution of the systems mentioned above. In particular, we derive finite-time results that are universal in the sense that the same relations between the non-equilibrium dynamics and the initial profiles hold for any unitary CFT. These results also make clear that heat and charge transport in standard CFT are purely ballistic.

    Finally, we propose and study an inhomogeneous CFT model with v(x) given by a random function. We argue that this model naturally emerges as an effective description of one-dimensional quantum many-body systems with certain static random impurities. Using tools from wave propagation in random media, we show that such impurities lead to normal and anomalous diffusive contributions to heat transport on top of the ballistic one known from standard CFT.

    Understanding Composition–Structure–Bioactivity Correlations in Bioactive Glasses2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Bioactive glasses integrate with bone/tooth tissues by forming a layer of hydroxy-carbonate apatite (HCA), which mimics the composition of bone mineral. In the current thesis, we investigated composition–structure–bioactivity correlations of phosphosilicate and borophosphosilicate (BPS) glasses. Bioactive phosphosilicate glasses extend the compositional space of the ”45S5 Bioglass®”, which has been in clinical use for decades. Recently developed bioactive BPS glasses with SiO2→B2O3 substitutions transform more completely into HCA and their glass dissolution behaviors can be tuned by varying the relative contents of B and Si. 

    It is known that the average silicate network connectivity NSi and the phosphate content (x(P2O5)) affect the apatite formation (in vitro bioactivity) of phosphosilicate glasses, but the details remain poorly explored. Three series of phosphosilicate glasses were designed by independently varying NSi and x(P2O5). After immersion of the glasses in a simulated body fluid (SBF) for 24 hours, different degrees of their apatite formation were quantified by Fourier-transform infrared (FTIR) spectroscopy. The results revealed that a high P content widened the NSi range that generated optimum amounts of apatite and also mitigated the detrimental effects associated with using glass particles with < 50 μm. The amounts of apatite derived from FTIR agreed with those from 31P magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy. The growth of apatite at bioactive glass surfaces was found to follow a sigmoidal growth model, in which the precursor phase, amorphous calcium phosphate (ACP), formed in the induction period and then crystallized into HCA in the following proliferation period, with an improvement in the structural ordering of HCA in the maturation period. This formation process closely resembles the apatite precipitated spontaneously from supersaturated Ca/P-containing solutions. The simultaneous growth of ACP and HCA is discussed in conjunction with a previously proposed mechanism for explaining in vitro bioactivity and apatite growth from bioactive glasses. 

    The short- and medium- range structures of bioactive borophosphosilicate (BPS) glasses were investigated by solid-state MAS NMR. Two series of BPS glasses were designed by gradually replacing SiO2 with B2O3 in the 45S5 glass, as well as another base glass featuring a more condensed glass network. As the B2O3 content is increased, the glass networks become more polymerized, together with decreased fractions of the dominating BO3 and orthophosphate units. Borate groups are homogeneously mixed with the isolated orthophosphate groups, while the remaining phosphate groups exhibit a slight preference for bonding to BO4 over SiO4 units. Linkages among borate groups are dominated by B[3]–O–B[4] linkages at the expenses of B[3]–O–B[3] and B[4]–O–B[4] linkages, with the latter B[4]–O–B[4] motifs disfavored yet abundant. A similar fashion of borate mixing was observed in P-free Na/Ca-based borosilicate glasses that span a large compositional space. The content of B[4]–O–B[4] linkages was found to be controlled by the relative fractions of BO4 groups and non-bridging oxygen ions.

    Understanding The Global Nursing perspective2018Inngår i: Open Access Journal of Nursing, ISSN 2639-1783, Vol. 1, nr 2, s. 77-81Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A critical consideration of the global nursing perspective is recommended when advocating enhanced global awareness in nursing practice, education and research. Adequate knowledge transfers in global nursing are noted when nurses make appropriate choices in care actions and identify power hierarchies. The utilisation of nurses’ professional competence with respect to vulnerability in health is suggested and by focusing on inequalities in health and social justice issues in existing care hierarchies, an advancement of the patterns in global nursing discipline can be observed. This paper postulates that the global nursing discourse can be applied in nursing practice, education and research and make a contribution to equal healthcare.

    Wearable Solutions for P-Health at Work: Precise, Pervasive and Preventive2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    With a demographic change towards an older population, the structure of the labor force is shifting, and people are expected to work longer within their extended life span. However, for many people, wellbeing has been compromised by work-related problems before they reach the retirement age. Prevention of chronic diseases such as cardiovascular diseases and musculoskeletal disorders is needed to provide a sustainable working life. Therefore, pervasive tools for risk assessment and intervention are needed. The vision is to use wearable technologies to promote a sustainable work life, to be more detailed, to develop a system that integrates wearable technologies into workwear to provide pervasive and precise occupational disease prevention. This thesis presents some efforts towards this vision, including system-level design for a wearable risk assessment and intervention system, as well as specific insight into solutions for in-field assessment of physical workload and technologies to make smart sensing garments. The overall system is capable of providing unobtrusive monitoring of several signs, automatically estimating risk levels and giving feedback and reports to different stakeholders. The performance and usability of current energy expenditure estimation methods based on heart rate monitors and accelerometers were examined in occupational scenarios. The usefulness of impedance pneumography-based respiration monitoring for energy expenditure estimation was explored. A method that integrates heart rate, respiration and motion information using a neuronal network for enhancing the estimation is shown. The sensing garment is an essential component of the wearable system. Smart textile solutions that improve the performance, usability and manufacturability of sensing garments, including solutions for wiring and textile-electronics interconnection as well as an overall garment design that utilizes different technologies, are demonstrated.

    A realist process evaluation within the Facilitating Implementation of Research Evidence (FIRE) cluster randomised controlled international trial: an exemplar2018Inngår i: Implementation Science, ISSN 1748-5908, E-ISSN 1748-5908, Vol. 13, nr 1, artikkel-id 138Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Facilitation is a promising implementation intervention, which requires theory-informed evaluation. This paper presents an exemplar of a multi-country realist process evaluation that was embedded in the first international randomised controlled trial evaluating two types of facilitation for implementing urinary continence care recommendations. We aimed to uncover what worked (and did not work), for whom, how, why and in what circumstances during the process of implementing the facilitation interventions in practice.

    METHODS: This realist process evaluation included theory formulation, theory testing and refining. Data were collected in 24 care home sites across four European countries. Data were collected over four time points using multiple qualitative methods: observation (372 h), interviews with staff (n = 357), residents (n = 152), next of kin (n = 109) and other stakeholders (n = 128), supplemented by facilitator activity logs. A combined inductive and deductive data analysis process focused on realist theory refinement and testing.

    RESULTS: The content and approach of the two facilitation programmes prompted variable opportunities to align and realign support with the needs and expectations of facilitators and homes. This influenced their level of confidence in fulfilling the facilitator role and ability to deliver the intervention as planned. The success of intervention implementation was largely dependent on whether sites prioritised their involvement in both the study and the facilitation programme. In contexts where the study was prioritised (including release of resources) and where managers and staff support was sustained, this prompted collective engagement (as an attitude and action). Internal facilitators' (IF) personal characteristics and abilities, including personal and formal authority, in combination with a supportive environment prompted by managers triggered the potential for learning over time. Learning over time resulted in a sense of confidence and personal growth, and enactment of the facilitation role, which resulted in practice changes.

    CONCLUSION: The scale and multi-country nature of this study provided a novel context to conduct one of the few trial embedded realist-informed process evaluations. In addition to providing an explanatory account of implementation processes, a conceptual platform for future facilitation research is presented. Finally, a realist-informed process evaluation framework is outlined, which could inform future research of this nature.

    Simulation of a Mining Value Chain with a Synthetic Ore Body Model: Iron Ore Example2018Inngår i: Minerals, ISSN 2075-163X, E-ISSN 2075-163X, Vol. 8, nr 11, artikkel-id 536Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Reconciliation of geological, mining and mineral processing information is a costly and time demanding procedure with high uncertainty due to incomplete information, especially during the early stages of a project, i.e., pre-feasibility, feasibility studies. Lack of information at those project stages can be overcome by applying synthetic data for investigating different scenarios. Generation of the synthetic data requires some minimum sparse knowledge already available from other parts of the mining value chain, i.e., geology, mining, mineral processing. The aim of the paper is to describe how to establish and construct a synthetic testing environment, or “synthetic ore body model” for data integration by using a synthetic deposit, mine production, constrained by a mine plan, and a simulated beneficiation process. The approach uses quantitative mineralogical data and liberation information for process simulation. The results of geological and process data integration are compared with the real case data of an apatite iron ore. The discussed approach allows for studying the implications in downstream processes caused by changes in upstream parts of the mining value chain. It also opens the possibility of optimising sampling campaigns by investigating different synthetic drilling scenarios including changes to the spacing between synthetic drill holes, composite length, drill hole orientation and assayed parameters. A synthetic deposit model can be a suitable tool for testing different scenarios for implementation of geometallurgical programs and also an educational tool for universities and companies.

    A City-Wide Real-Time Traffic Management System: Enabling Crowdsensing in Social Internet of Vehicles2018Inngår i: IEEE Communications Magazine, ISSN 0163-6804, E-ISSN 1558-1896, Vol. 56, nr 9, s. 19-25Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    As an emerging platform based on ITS, SIoV is promising for applications of traffic management and road safety in smart cities. However, the end-to-end delay is large in store-carry-and-forward-based vehicular networks, which has become the main obstacle for the implementation of large-scale SIoV. With the extensive applications of mobile devices, crowdsensing is promising to enable real-time content dissemination in a city-wide traffic management system. This article first provides an overview of several promising research areas for traffic management in SIoV. Given the significance of traffic management in urban areas, we investigate a crowdsensing-based framework to provide timely response for traffic management in heterogeneous SIoV. The participant vehicles based on D2D communications integrate trajectory and topology information to dynamically regulate their social behaviors according to network conditions. A real-world taxi trajectory analysis-based performance evaluation is provided to demonstrate the effectiveness of the designed framework. Furthermore, we discuss several future research challenges before concluding our work.

    Detecting Ponzi Schemes on Ethereum: Towards Healthier Blockchain Technology2018Inngår i: WWW '18: Proceedings of the 2018 World Wide Web Conference, ACM Digital Library, 2018, s. 1409-1418Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Blockchain technology becomes increasingly popular. It also attracts scams, for example, Ponzi scheme, a classic fraud, has been found making a notable amount of money on Blockchain, which has a very negative impact. To help dealing with this issue, this paper proposes an approach to detect Ponzi schemes on blockchain by using data mining and machine learning methods. By verifying smart contracts on Ethereum, we first extract features from user accounts and operation codes of the smart contracts and then build a classification model to detect latent Ponzi schemes implemented as smart contracts. The experimental results show that the proposed approach can achieve high accuracy for practical use. More importantly, the approach can be used to detect Ponzi schemes even at the moment of its creation. By using the proposed approach, we estimate that there are more than 400 Ponzi schemes running on Ethereum. Based on these results, we propose to build a uniform platform to evaluate and monitor every created smart contract for early warning of scams.

    Introduktionsverksamhet för nyanlända elever i grundskolans tidiga år2018Licentiatavhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    Children who migrate to Sweden are usually introduced to the Swedish school through some kind of introduction programme in their new community. This study examines the experiences of newly arrived children participating in school introduction in the early school years, as well as the experiences of the teachers and principals working with the programme. In the community in which this study is situated, newly arrived children participate in a special school unit where the goal is to map their experiences and skills from former education, and where the teaching of Swedish as a second language is seen as an important part of the introduction.

    Forty-two interviews (40 individual and 2 pairs) were conducted with principals, teachers and newly arrived children (ages appropriate for Years 2, 3, 4 and 5 in elementary school). Employing a social constructivist perspective, together with inspiration from Critical Discourse Analysis, the study aimed at outlining the discourses the participants draw on when speaking about the school introduction and how these discourses affect the participants’ positioning of themselves and other participants in the school practice. Fairclough’s theory of discourse (1992, 2001) provides an understanding of how participants experience being part of the school introduction as well as their own and other participants’ positions in the school practice due to ambient discourses.

    The results indicate that four discourses dominate the practice and affect the participants’ view of each other and themselves as well as their possibilities to impact the practice and their own situation as being a part of it. The four discourses that were identified are described as 1) the Swedish language as a key to success in school, 2) the adjustment of behaviour as a key to success in school, 3) the substantial immigration as a challenge, and 4) heed.

    When robot personalisation does not help: Insights from a robot-supported learning study2018Inngår i: 27th IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN), 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the domain of robotic tutors, personalised tutoring has started to receive scientists' attention, but is still relatively underexplored. Previous work using reinforcement learning (RL) has addressed personalised tutoring from the perspective of affective policy learning. However, little is known about the effects of robot behaviour personalisation on user's task performance. Moreover, it is also unclear if and when personalisation may be more beneficial than a robot that adapts to its users and the context of the interaction without personalising its behaviour. In this paper we build on previous work on affective policy learning that used RL to learn what robot's supportive behaviours are preferred by users in an educational scenario. We build a RL framework for personalisation that allows a robot to select verbal supportive behaviours to maximise the user's task progress and positive reactions in a learning scenario where a Pepper robot acts as a tutor and helps people to learn how to solve grid-based logic puzzles. A between-subjects design user study showed that participants were more efficient at solving logic puzzles and preferred a robot that exhibits more varied behaviours compared with a robot that personalises its behaviour by converging on a specific one over time. We discuss insights on negative effects of personalisation and report lessons learned together with design implications for personalised robots.

    Seafood Life Cycle Inventory database : Methodology and Principles and Data Quality Guidelines2018Rapport (Annet vitenskapelig)
    Abstract [sv]

    En växande insikt om betydelsen av livsmedel för global miljöpåverkan, särskilt animaliska livsmedel inklusive sjömat, har lett till ett behov hos producenter såväl som handeln att kommunicera miljöpåverkan av råvaror och produkter genom livsmedelskedjan. Detta visar sig i form av nya krav på att dokumentera produkters miljöavtryck, t ex vid certifiering och i regelverk. EU initiativet inom hållbar utveckling med en "inre marknad för gröna produkter" är ett exempel, med målet att dokumentera miljöavtrycket av produkter på EU marknaden enligt metoden Product Environmental Footprinting (PEF). Målet är att göra det möjligt för konsumenter, handel, producenter och lagstiftare att göra medvetna val och att etablera drivkrafter mot reducerad miljöpåverkan i produkters värdekedja.

    För att kunna leva upp till dessa nya krav, krävs tillgång på representativ data av hög kvalitet, något som i stort sett har saknats för sjömatsprodukter. För att göra högkvalitativa, representativa data kring resursåtgång och miljöpåverkan av sjömatsprodukter (inklusive biomassa som direkt eller indirekt används till foder) tillgängliga, initierade den norska sjömatsbranschen ett pilotprojekt. Projektet definierade en rekommenderad metod och struktur för datainsamling och använde denna metod för att samla in tillgängliga data för ett antal pilotfall. Metoden för datainsamling presenteras i detta dokument och kan, tillsammans med pilotdataseten som gjorts tillgängliga i projektet, användas av näringen som grund för en bredare datainsamling för att skapa en utbyggd sjömats-LCI-databas.

    Screening test methods for determination of fire spalling of concrete2018Rapport (Annet vitenskapelig)
    Abstract [en]

    The fire resistance of concrete structures is generally good, but for some types of concrete fire spalling can reduce the fire resistance significantly. Therefore, methods are needed to predict whether a concrete will spall when exposed to fire and the severity of spalling.

    The objective of the present project was to develop an intermediate scale test method for the evaluation of the spalling behavior of concrete. The test method shall be cost effective and enable screening of different concretes before a full scale approval test is performed. A number of different intermediate scale test methods have been evaluated regarding the precision to reproduce the spalling behavior of that observed in full scale tests.

    Of the different test specimen shapes and methods, a circular test specimen where the concrete is casted in a steel tube has shown the best correlation to the full scale tests performed. This specimen is easy to produce, and the fire test can be performed on a small furnace.

    Sänkning av kväveoxidemissioner samt förlängd livslängd genom rökgasåterföring i en pelletsbrännare 750 kW2017Rapport (Annet vitenskapelig)
    Abstract [en]

    The project has been involved in developing a flue gas recirculation system aimed at reducing emissions of NO

    x and dust, as well as extending the life of the material in a pellet burner. Installation of a flue gas recirculation system and combustion tests have been performed in a laundry in Bengtsfors, which has a pellet-fired boiler with two janfire burners of 750 kW each. The results of the tests showed that the flue gas recirculation had an impact on NOx emissions. These decreased by about 17-18% in wood pellets combustion and by 10% in combustion of nitrogen rich agro fuel pellets in comparison to non-flue gas recirculation. With flue gas recirculation, the combustion furnace temperatures decreased by 85-105 oC for wood pellets and about 70 oC for agro fuel pellets.

    Tekniska och ekonomiska förutsättningar för oljeersättning i industrin med pyrolysolja2017Rapport (Annet vitenskapelig)
    Abstract [en]

    For potential users, especially in the industry, which consider bio-oil as well as pyrolysis oil as a fuel alternatives in the future, in-depth knowledge of its technical and economic conditions in various industrial applications is required. To verify which requirements these oils sets on the combustion technology more combustion tests in potential burners are needed to clarify any technical development. To minimize any problems that may arise with pyrolysis oil, from delivery to storage and combustion, the available knowledge about the use of common bio-oils should be used. The overall objective of this project is to investigate the possibilities to use pyrolysis oil in various industrial applications.

    Fire Safety Engineering for Innovative and Sustainable Building Solutions2017Rapport (Annet vitenskapelig)
    Abstract [en]

    The Nordic fire safety engineering project for innovative and sustainable building solutions, funded by Nordic Innovation, SBUF (the Swedish construction industry's organisation for research and development) and DIBK (the Norwegian National Office of Building Technology and Administration), started in June 2014 and ended in August 2017. The aim of this project was the production of practical specifications on two areas within fire safety engineering:

    • Standard on Probabilistic Method to Verify Fire Safety Design in Buildings
    • Standard on Control in the Building Process

    What has been developed is tailored for the Nordic context which is a region that has used fire safety engineering for a relatively long time. This project supported Nordic harmonization of fire safety which in the end may facilitate trade of services and products.

    Furthermore, and in order to cover the Nordic context, all Nordic countries have been represented by at least one project partz§ner. The following table shows all the partners as well as their country of origin.

    The ultimate challenge or just common sense : The present practices and future opportunities to increase the utilization of livestock manure as organic fertilizer in North West Russia2017Rapport (Annet vitenskapelig)
    Abstract [en]

    The ultimate challenge or just common sense

    The present practices and future opportunities to increase the utilization of livestock manure as organic fertilizer in North West Russia

    The risk of nutrient contamination of surface- and groundwater’s from livestock farming has been one of the issues to address in international cooperation initiatives in the Baltic Sea Region during the recent decade. In particular, international initiatives targeting North West Russia in the 2000-2010’s by HELCOM and NEFCO and as bilateral cooperation with Russia by Finland and Sweden have assessed the severity of the threat, have introduced technical solutions to process livestock manure and have explored the market potential for fertilizer products made through processing of livestock manure. However, a comprehensive resolution to the growing problem still remains a long term goal and many of the barriers to increase manure processing and organic fertilization – poor economic incentives and lack of proven cost-efficient technologies – still prevail.

    In Russia, ongoing adaptation of state support to agriculture as part of the WTO membership brings about indirect area-based farm support and increased share of support to investments in farm infrastructure, rural development and in management of health, hygienic and environmental aspects. These represent positive opportunities for increasing sustainable manure management and the proportion of manure-based fertilization. The Technological Regulations (TR) instrument introduced in 2008, enhanced enforcement and systematic introduction of BAT in Russian agriculture, provide a set of management tools which has good potential to be effective for the administration and be accepted by the agricultural companies. At the same time, there is a risk that the increasing concentration of livestock, in particular poultry production in Leningrad Oblast narrows alternative paths for sustainable manure management and is leading to a situation in which only large scale technological solutions may prove to be viable in order to solve the issue on the regional scale.

    This report reviews the current environment in North West Russian Federation to advance sustainable animal manure management and reflects this against the EU context with related examples from Latvia. The report concludes that a sustainable future for North West Russian agriculture relies on the overall sustainability of the enterprises and that regulative and subsidy measures should reinforce the positive link between economic and environmental benefit. Spatial aspects on the territorial level should be

    addressed as the location of agricultural enterprises both relative to each other and relative to human settlements have increasing importance from the perspective of environmental, health and biosecurity implications. Thirdly, Russia’s adaptation to the WTO framework, the process of implementing BAT in agriculture and the TR instrument to support holistic farm specific solutions provide a range of interesting topics for future international cooperation on both technical and policy levels.

    Multicomponent fractionation of Saccharina latissima brown algae using chelating salt solutions2016Inngår i: Journal of Applied Phycology, ISSN 0921-8971, E-ISSN 1573-5176, Vol. 28, nr 4, s. 2561-2574Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A fractionation strategy for Saccharina latissima algal biomass was developed utilizing chelating extraction salt solutions to mediate the liberation of algal components. Alginate, cellulose, laminarin, mannitol, protein, and inorganic salts were quantified in the fractions to reveal their individual dissolution patterns. Chelation power was identified as a key parameter for liberating alginate and increasing the yield of extracted components. The most efficient fractionation was achieved using aqueous sodium citrate as the extraction solution, producing an alginate-rich soluble fraction and a salt-poor insoluble fraction rich in cellulose and protein. Extractions at decreased pH were shown to be beneficial because they decreased the M/G ratio of the extracted alginate and concentrated the protein in the insoluble fraction from which it can easily be recovered; these effects could be achieved by switching the traditional sodium carbonate extraction solution with salts that have chelation capacity at lower pH. A cyclic extraction demonstrated that the sodium citrate solution can be reused for multiple alginate extractions with the buildup of the concentrations of other valuable components in the solution.

    Fast and Reliable Initial Access with Random Beamforming for mmWave NetworksManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Millimeter-wave (mmWave) communications rely on directional transmissions to overcome severe path loss. Nevertheless, the use of narrow beams complicates the initial access procedure and increase the latency as the transmitter and receiver beams should be aligned for a proper link establishment. In this paper, we investigate the feasibility of random beamforming for the cell-search phase of initial access. We develop a stochastic geometry framework to analyze the performance in terms of detection failure probability and expected latency of initial access as well as total data transmission. Meanwhile, we compare our scheme with the widely used exhaustive search and iterative search schemes, in both control plane and data plane. Numerical results show that, compared to the other two schemes, random beamforming can substantially reduce the latency of initial access with comparable failure probability in dense networks. We show that the gain of the random beamforming is more prominent in light traffics and low-latency services. Our work demonstrates that developing complex cell-discovery algorithms may be unnecessary in dense mmWave networks and thus shed new lights on mmWave network design.

    Abstract [en]

    In 1991 the present author found, in the collection of old Slavic prints at the Uppsala University Library, a hitherto unobserved parchment fragment of Slavic origin. The fragment had been used as binding material in a psalter, printed in Lviv in 1615. It was revealed to consist of two leaves, having possibly once constituted a bifolium. The fragment is published here with introductory comments.

    The author’s analysis dates the fragment to the 13th century. The language is Russian Church Slavonic with some south-western (“Ukrainian”) traits. The text consists of a number of hymns, all connected to the baptism of Christ. Most of these hymns are part of a canon sung on the Forefeast of the Theophany of our Lord, and the redaction appears quite old. It is not fully clear which type of liturgical book the fragment stems from, but the hymns are most likely taken from a Menaion (Минея служебная). Nothing of the kind has previously been found in Sweden.

    Probing Catalytic Reaction Mechanisms of Biomimetic Diiron Complexes with Time-resolved Absorption Spectroscopy2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Directed design of improved molecular catalysts for hydrogen evolution reactions relies on rational benchmarking based on detailed understanding about the mechanism of catalysis. Specifically, investigation of multi-electron redox catalysis, with structural characterization of catalytic intermediates, combined with the kinetics of their transformations, can reveal the rate-limiting step of the overall reaction, possible degradation pathways and the function of structural motives. However, direct spectroscopic observation of catalytic intermediates is in most cases not available due to the rapid turnover of efficient catalysts.

    In this thesis, time-resolved absorption spectroscopy with UV-Vis and mid-IR detection was used to identify catalytic reaction intermediates and account for kinetics relevant to elementary reactions steps of H2 formation on a nanosecond to second time scale. For a class of FeIFeI (S-R-S)(CO)6-n(PMe3)n complexes (R = propyl, benzyl or azapropyl), inspired by the active site of FeFe-hydrogenase, the key intermediates formed in different catalytic pathways have been characterized. These complexes typically feature very similar geometry coordination, but show different structural rearrangement upon reduction. This might be applied to elucidate their differences in protonation dynamics. Protonation kinetics of singly reduced species, forming bridging hydride, indicate a direct proton transfer step in the FeIFe0 state, in contrast to that of the neutral complex (FeIFeI state) with phosphine ligands (PMe3) in which the hydride formation is likely mediated by one of the CO-ligands, as had been proposed. In catalysis of FeFe-hydrogenase, the amine function of the bridgehead is known to assist enzymatic H2 formation by proton shuttling. The same role in catalysis by synthetic diiron complex with the azapropyl bridgehead had been proposed. However, our results show that for the synthetic complex, the aza-group has no role as proton shuttle in the hydride formation in the FeIFe0 state. Instead, the effect of aza protonation is to lower the catalyst overpotential, but does not slows down the hydride formation by external proton.  For complex with benzyl bridgehead, the rigid and unsaturated bridging ligand generally lower the reduction potential and stabilize the reduced forms. This allows to characterize the overall catalytic processes, i.e exact structure of hydride intermediate, turnover process, etc.

    Ukrainian Colour Concepts for Blue2013Inngår i: Slovo : Journal of Slavic Languages and Literatures, ISSN 0348-744X, E-ISSN 2001-7359, Vol. 54, s. 150-163Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A much-studied area, colour categorization has received renewed attention in cognitive linguistics. A promising line of research is the reconstruction of colour concepts. Specifically, the goal is to discover points of reference used by a linguistic community for different colours. The colour system of Ukrainian is special in that it has as many as three basic words (synij, blakytnyj and holubyj) for what is generally called blue in English. This paper analyzes experimental and corpus data and offers a reconstruction of their referential models. The Ukrainian colour names under study are shown to have a dominant reference point (a clear sky for all three words) and secondary ones. Relevant aspects of typical observation situations and other contributing factors are discussed.

    This article examines the multilingualism of a new generation of Russian-speaking immi- grants in Finland. The main focus in the article is on immigrants’ use of and competency in Finnish and Russian, as well as the meaning of these languages for persons immigrating at different stages in their lives. The article also describes how these immigrants view their lin- guistic situation and possibilities for maintaining and developing different languages. Finally, conclusions will be drawn about the possibilities for, and constraints on, the multilingualism of speakers of Russian in Finnish society. This article is based on two studies: a longitudinal case-study on young Russian-speaking immigrants, and a study of working-age Russian- speaking migrants within the project “Transforming Professional Integration” (ISIS). The data consist of thematic interviews with Russian-speaking migrants living in Finland. Principles of qualitative content analysis were applied in analyzing the data.

    Abstract [en]

    In the autumn of 1934, the Soviet writer Vera Inber (1890-1972) made a three months’ journey through the Nordic countries. The journey was undertaken on the invitation of Swedish and Norwegian student organizations and friendship societies. She met with journalists and writer-colleagues, gave talks in Stockholm, Uppsala, Oslo, Bergen, Copenhagen and Aarhus and collected material for a planned book about life in modern Scandinavia. In numerous interviews she praised the victories of socialism, the successful solution to the “women’s question” and the visible role of writers in the Soviet Union. When stating that “it’s wonderful to be a Soviet writer”, Inber was in fact at this point of her career passing from being a talented, highly original author of short stories and poems to becoming an obedient tool in the hands of the Communist Party.

    This article discusses transformations of Lenin’s slogan Коммунизм – это есть Советская власть плюс электрификация всей страны as used in contemporary Russian news discourse and the expressive meanings that they convey. The material, consisting of approximately 1,500 instances, was collected from the electronic database Integrum. The article opens with a brief discussion of linguistic expressivity and a short description of the history of transformations of the slogan. The results of the study demonstrate that transformations of the slogan in its entirety tend to occur within the text and to convey varying degrees of negative attitudes, which may appear either through the wording of the transformations or through context. Transformations of only the last part of the slogan are used mostly as headlines or subheadings. With these transformations, it is almost always necessary to read the text in order to grasp the intended positive or negative attitude.

    Computational Modeling of the Vocal Tract: Applications to Speech Production2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Human speech production is a complex process, involving neuromuscular control signals, the effects of articulators' biomechanical properties and acoustic wave propagation in a vocal tract tube of intricate shape. Modeling these phenomena may play an important role in advancing our understanding of the involved mechanisms, and may also have future medical applications, e.g., guiding doctors in diagnosing, treatment planning, and surgery prediction of related disorders, ranging from oral cancer, cleft palate, obstructive sleep apnea, dysphagia, etc.

    A more complete understanding requires models that are as truthful representations as possible of the phenomena. Due to the complexity of such modeling, simplifications have nevertheless been used extensively in speech production research: phonetic descriptors (such as the position and degree of the most constricted part of the vocal tract) are used as control signals, the articulators are represented as two-dimensional geometrical models, the vocal tract is considered as a smooth tube and plane wave propagation is assumed, etc.

    This thesis aims at firstly investigating the consequences of such simplifications, and secondly at contributing to establishing unified modeling of the speech production process, by connecting three-dimensional biomechanical modeling of the upper airway with three-dimensional acoustic simulations. The investigation on simplifying assumptions demonstrated the influence of vocal tract geometry features — such as shape representation, bending and lip shape — on its acoustic characteristics, and that the type of modeling — geometrical or biomechanical — affects the spatial trajectories of the articulators, as well as the transition of formant frequencies in the spectrogram.

    The unification of biomechanical and acoustic modeling in three-dimensions allows to realistically control the acoustic output of dynamic sounds, such as vowel-vowel utterances, by contraction of relevant muscles. This moves and shapes the speech articulators that in turn dene the vocal tract tube in which the wave propagation occurs. The main contribution of the thesis in this line of work is a novel and complex method that automatically reconstructs the shape of the vocal tract from the biomechanical model. This step is essential to link biomechanical and acoustic simulations, since the vocal tract, which anatomically is a cavity enclosed by different structures, is only implicitly defined in a biomechanical model constituted of several distinct articulators.

    Is there a diffusion of alkali in the activation of dissolving cellulose pulp at low NAOH stoichiometric excess?2018Inngår i: Cellulose (London), ISSN 0969-0239, E-ISSN 1572-882XArtikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We conducted a quantitative study, following the degree of activation (i.e. the transformation to alkali cellulose, denoted as DoA) over time for dissolving cellulose pulp treated with different [NaOH] at low NaOH/anhydroglucose unit stoichiometric ratio (denoted as (r) ≤ 2.6). Our quantitative approach was based on Raman spectroscopy data, evaluated by partial least squares regression modelling. The results show strong influence of the (r) on DoA (increasing from DoA= 45% at (r) = 0.8, to DoA = 85% at (r) = 2.6), and its complex dependence on [NaOH]. At (r) = 0.8 the highest DoA (DoA ≳ 60%) was found at 30% [NaOH], while at (r) =1.3 it was found at 20% [NaOH] (DoA ≳ 80%). Although activation of cellulose happens in minutes at the studied temperature (30 °C), it was found that the reaction may be slow when a low (r) is used. A gradual increase of the DoA from ≈ 30% to ≈ 70% in time was seen when samples were activated with 30% [NaOH] at (r) = 0.8. At the same (r), a similar increase of DoA from ≈ 30 % to ≈ 60 % was also observed when 40% [NaOH] was used. Slow diffusion of NaOH through poorly swollen cellulose fibres is proposed as an explanation for this phenomenon. Lastly, solid-state CP/MAS NMR measurements suggest that at a fixed temperature, the Na-Cell allomorph mostly depends on [NaOH]. However, in the transition area between Na-Cell I and Na-Cell II, its influence might be affected by (r).

    Abstract [en]

    An exquisitely polite Turkish phrase, traditionally used by generous hosts at Ramadan celebrations, has through literal misunderstanding become an emblematic symbol for excesses in the Ottoman exploitation of the peoples of the empire. It is well entrenched in Bulgarian usage, but also found in the writings of Western travellers in the Ottoman Empire.

    Abstract [en]

    This article deals with European minority policy in general and German minority policy in particular. The four officially recognised minorities in Germany are presented alongside Low German, a regional language. Following an overview of the European minority conventions signed by Germany, a presentation is made of European minority policy which, for the most part, is implemented by the European minority organisation FUEN (Federal Union of European Nations). The initial part of the article ends with a presentation of the bodies, established in Germany during the last decade, concerned with minority issues. In the second part of the article, the focus is moved to a cursory description of the specific situations of each individual minority group in Germany, including the current situation facing the Sorbian people in Saxony and Brandenburg. Reference is made both to the coal-mining industry, which continues to threaten Sorbian villages with physical destruction, and to the establishment of the WITAJ-Language Centre (WITAJ-Sprachzentrum), an instrument of the linguistic revitalisation movement in Lusatia.

    The Applicability of a High-Intensity Functional Exercise Program among Older People with Dementia living in Nursing Homes2018Inngår i: Journal of Geriatric Physical Therapy, ISSN 1539-8412, E-ISSN 2152-0895Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background and Purpose: Exercise programs for people with dementia need to be optimized. We therefore evaluated the applicability of a high-intensity functional exercise program among people with dementia in nursing homes with regard to attendance, achieved exercise intensity, adverse events, a focus on dementia type, and whether symptoms of dementia or other medical conditions common in this population were associated with program applicability.

    Methods: The Umeå Dementia and Exercise study, a cluster-randomized controlled trial set in 16 nursing homes in Umeå, Sweden. Ninety-three people with dementia (mean [SD] Mini-Mental State Examination score of 15.4 [3.4]) were randomized to the exercise intervention. Thirty-four participants had Alzheimer's disease (AD) and 59 non-Alzheimer's dementia (non-AD). High-Intensity Functional Exercise (HIFE) program was conducted in groups of 3 to 8 participants. Two physiotherapists led 5 sessions (45 minutes each) per fortnight for 4 months (total 40 sessions).

    Results: Median attendance rate was 82.5%. Lower limb strength exercises were performed at high or medium intensity at a median interquartile range of 94.7% (77.8%-100%) of attended sessions. Participants with non-AD performed more sessions with high intensity in strength exercises than participants with AD (median interquartile range, 53.8% [25.7%-80%] vs 34.9% [2.02%-62.9%]; P = .035). Balance exercises were performed at high intensity at a median interquartile range of 75% (33.3%-88.6%). Adverse events (all minor and temporary, mostly musculoskeletal) occurred during the exercise sessions in 16% of attended sessions. Low motivation was the most common barrier for attendance. Buildup period, low motivation, and pain were common barriers for achieving high intensity in balance and strength exercises, and fear was a barrier in balance exercises. Of medical conditions, only behavioral and psychological symptoms of dementia, including apathy, were negatively associated with applicability.

    Conclusion: A group-based, supervised, and individualized high-intensity functional exercise program seems to be applicable with regard to attendance, achieved intensity, and adverse events during the exercise sessions, in people with mild to moderate dementia in nursing homes. Effective strategies to enhance motivation to participate in exercise, as well as prevention and treatment of pain and behavioral and psychological symptoms of dementia, are important when promoting exercise participation in this population.

    Abstract [en]

    Pluractionality is a syntactic, morphological and semantic category, which originally referred to verbs in the Chadic languages of Africa. Pluractional verbs prefer plural subjects and/or plural objects. Are there any traces of pluractivity in Polish? Most probably, some of frequentative and distributive verbs (like the prototypical pozagryzać ‘to bite’, on several objects, poprzyjeżdżać ‘to come’, performed by several agents) are pluractional, as they prefer plural agents or patients.

    Abstract [en]

    The number of Finnish loan words in Swedish is very limited, in spite of the long-standing contacts between the languages. The existing loan words were taken over during a long period of time, with the oldest ones appearing already in the late Middle Ages, and the later ones appearing in the early 20th century. It is important to elucidate where and when these words have been borrowed. Due to extensive geographical contact areas, however, this is no easy task. Earlier research probably exaggerated the role of Stockholm, whereas the importance of, for example, the provinces of Gästrikland and Ångermanland was underestimated. During the 17th century, these areas formed bridge-heads in the large-scale Finnish migration to present- day Sweden. Old mining centres, like Arboga, also seem to have been of importance as contact areas. There are indications that quite a few Finnish loan words were borrowed in that area. If Swedish rappakalja ’bad beer’ (< Finnish rapakalja) was also one of those, that could perhaps help to explain the Swedish expression, “to suffer the after-effects of Arboga beer”.

    Time and the Vanities of Existence in Antun Šoljan’s Fiction2014Inngår i: Slovo: Journal of Slavic Languages, Literatures and Cultures , ISSN 2001-7395, Vol. 55, s. 60-76Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper explores the theme of hope and hopelessness in a selection of Antun Šoljan’s stories and novels and how the author creates in his heroes an interior atmosphere of inquiry that is paradoxically laden with uncertainty and the human instinct to move forward. A “parabolic moralist” (as Davor Kapetanić has called him), Šoljan depicts the world as more than a simple continuity of events, political, personal, private or public. His major concern is to make sense of man’s existence in a universe that confronts him with both linear time and a repetitive or circular series of events. Examining the apparent contradictions of linear vs. circular existence, the author often places his characters “out of time” and analyzes any given life by finding its important events, actions and desires. While Šoljan’s heroes often conclude that temporal things are of little lasting value, he leaves his philosophically and psychologically battered heroes with at least a small possibility of hope.

    Motivation to participate in high-intensity functional exercise compared with a social activity in older people with dementia in nursing homes2018Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, nr 11, artikkel-id e0206899Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Motivation to participate in exercise among people with dementia has not been well studied. The symptoms of dementia, including apathy, may lead to low motivation to participate in exercise. The aim of this study was to evaluate the motivation of older people with dementia to participate in a high-intensity exercise program compared with motivation of those participating in a social group activity.

    Methods: The Umeå Dementia and Exercise Study (UMDEX) was a cluster-randomized controlled intervention trial including 186 people (mean age; 85, 75% female) with dementia in nursing homes. Participants were randomized to participate in the High-Intensity Functional Exercise (HIFE) Program (n = 93) or a seated social group activity (n = 93). The activities were conducted in groups of 3–8 participants for 45 minutes, five times per two-week period, for 4 months (40 sessions in total). Participants’ motivation to go to and during activity sessions were assessed by the activity leaders and nursing homes staff using a five-point Likert scale. Data were analyzed using cumulative link mixed models.

    Results: Motivation was high or very high during 61.0% of attended sessions in the exercise group and 62.6% in the social activity group. No overall significant difference between groups was observed, but motivation increased over time in the exercise group and decreased in the social activity group (p < 0.05). Motivation during the sessions was significantly higher than motivation to go to the sessions, especially in the exercise group [OR 2.39 (95% CI 2.38–2.40) and 1.50 (95% CI 1.32–1.70), respectively].

    Conclusions: Among older people with dementia in nursing homes, motivation to participate in a high-intensity functional exercise program seems to be high, comparable to motivation to participate in a social activity, and increase over time. Since motivation during activity sessions was higher than motivation to go to sessions the promotion of strategies to encourage people with dementia to join exercise groups is of great importance.

    Blood flow and cell transport in arteries and medical assist devices2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The cardiovascular system is responsible for transport of nutrients, oxygen, as well as the cells and molecules making up the immune system. Through the hemostatic system, the body maintains the integrity of the blood vessels, and prevents bleeding. The biochemical and physical processes governing the circulation interact, and take place at a large range of time and length scales - from those related to the individual cells up to the large scale flow structures. Dysfunctions of the heart or the circulatory system may have severe consequences. Cardiovascular diseases (CVD) is a heterogeneous group of diseases, responsible for about 50% of all death cases in the western world.

    Patients with severe but transient heart and/or lung disease may require the assistance of a heart-lung machine to bridge over the period required for the affected organ to recover. One such system is the Extracorporeal Membrane Oxygenator (ECMO) circuit, consting of a blood pump, a membrane oxygenator, cannulae and tubing system. While the therapy is life-saving, it is associated with relatively frequent thromboembolic (blood clotting and/or bleeding) events. Modeling of the flow in some components of the ECMO circuit was undertaken. The flow data was used together with models for platelet activation to assess the risk for thrombus formation. The results indicated locations of elevated risk of thrombosis in the centrifugal blood pump, the ECMO cannulae and the pipe connectors. The identified locations agreed well with clinical observations. The results lead to a direct recommendation to minimize the use of tube connectors. Further study of the sensitivity of the platelet activation models to uncertainties and errors was carried out. Some recommendations for improved modeling were proposed.

    Arteriosclerosis develops slowly over a long period of time (years or decades). It manifests initially at some common sites; arteries of certain sizes with relatively strong flow rate, as well as near artery bifurcations and locations of strong vessel curvature. The location specificity indicates that the blood flow plays a central role in the arteriosclerotic process. Being able to predict the future development of arteriosclerotic lesion and its location for an individual patient would imply that pre-emptive actions could be taken. This idea was the foundation of some of the numerical simulations in this thesis. A stenoted patient specific renal artery was considered, and was reconstructed to a non-pathological state by removing the stenosis using different segmentation methods. We could then evaluate if common stenosis markers based on functions of time-averages of the Wall Shear-Stress (WSS) could be use as predictive parameters. It was shown that these markers are not adequate as predictive tools. Furthermore, it was shown that the sensitivity to reconstruction technique was at least of the same order as the effect of the choice of blood rheology model. The rheology of blood was further studied through detailed simulations resolving the blood plasma flow and its interaction with the red blood cells (RBC) and the platelets. A hybrid Immersed boundary-Lattice Boltzmann method was applied, and the rheological data was compared to the Quemada model. It was found that the Quemada model could underpredict the effective viscosity by as much as 50%. The same methodology was applied to study the transport of RBCs and platelets, and the influence of RBC polydispersity. An increased degree of variability in RBC volume was found, under certain circumstances, to lead to an increase of the transport of platelets to the vessel wall (margination).

    Baseball, glima and Gotlandic sport: An analysis of the demonstration sports in the 1912 Stockholm Olympics2018Inngår i: Diagoras: International Academic Journal on Olympic Studies, Vol. 2, s. 103-122Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The purpose of the study is to analyse the demonstration sports (baseball, glima and Gotlandic sport) into the 1912 Stockholm Olympics. Who took the initiative for the demonstration sports? The IOC or the Swedish Organising Committee? How were the demonstration sports received by the public and the press, and what was their legacy? The study is based mainly on primary sources from the 1912 Stockholm Olympics’ archive. The 1912 Stockholm Olympics has been well explored, mainly by Swedes and internationals, and this gives a good picture of the 1912 Stockholm Olympics from different perspectives. On the other hand, research into the demonstration sports in the Olympic Games is clearly limited and there is thus a great need for further studies. This current study covers just a small part of this need. The results show that in 1912 there was no considered strategy on the part of either the IOC or the Swedish Organising Committee concerning the demonstration sports. The initiative for the demonstration sports came from individual representatives of each type of sport, and the Swedish organisers were positive towards three of those proposed: baseball, glima and Gotlandic sport. The Swedish organisers had control over which demonstration sports would be included in the programme. This meant that the choice of demonstration sports lay beyond the control of the 1912 IOC, but this would change in the 1900s. During the games they were given limited attention at most, both publicly and in the press. The demonstration sports were removed from the Olympic programme before the 1992 Olympic Games.
