    Introduktionsverksamhet för nyanlända elever i grundskolans tidiga år2018Licentiate thesis, monograph (Other academic)
    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.

    Seafood Life Cycle Inventory database : Methodology and Principles and Data Quality Guidelines2018Report (Other academic)
    Abstract [en]

    An increasing awareness about the important role of food, in particular animal-based foods including seafood, for global environmental impacts has led to a need of producers as well as retailers to communicate environmental impacts of raw materials and products through the food chain. This is demonstrated by new requirements to document the environmental footprints of products, e.g. by certification schemes and policies. The EU policy for sustainable development with its "single market for green products" is one example, aiming for documenting the environmental footprint of products on the EU market according to the Product Environmental Footprint (PEF) method. The goal is to enable consumers, retailers, producer, regulators and policy makers to make conscious choices and establish drivers for reducing environmental impacts throughout product supply chains.

    To be able to live up to these new requirements, representative data of high quality is needed, something which has largely been missing for seafood products. To make high-quality, representative data on the resource use and environmental impacts caused by seafood products (including biomass used directly or indirectly for feed) available, the Norwegian seafood industry initiated a pilot project. The project defined a recommended method and structure for data collection and used this method to collect available data for a number of pilot cases. The method for data collection is presented in this document and can, together with the pilot data sets made available through the project, be used by the industry as a basis for a broader data collection to create an expanded seafood LCI database.

    Screening test methods for determination of fire spalling of concrete2018Report (Other academic)
    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 kW2017Report (Other academic)
    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 pyrolysolja2017Report (Other academic)
    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 Solutions2017Report (Other academic)
    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 Russia2017Report (Other academic)
    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.

    Probing Catalytic Reaction Mechanisms of Biomimetic Diiron Complexes with Time-resolved Absorption Spectroscopy2018Doctoral thesis, comprehensive summary (Other academic)
    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.

    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.

    Ukrainian Colour Concepts for Blue2013In: Slovo : Journal of Slavic Languages and Literatures, ISSN 0348-744X, E-ISSN 2001-7359, Vol. 54, p. 150-163Article in journal (Refereed)
    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.

    Abstract [en]

    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.

    “It’s wonderful to be a Soviet writer!” Vera Inber’s Northern Journey in 19342013In: Slovo : Journal of Slavic Languages and Literatures, ISSN 0348-744X, E-ISSN 2001-7359, Vol. 54, p. 19-48Article in journal (Refereed)
    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.

    Abstract [en]

    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 Production2018Doctoral thesis, comprehensive summary (Other academic)
    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.

    Zakhar Prilepin’s novel The Мonastery (Obitel’, 2014) combines traits of the novel of development (Bildungsroman), camp prose (lagernaia proza), and other genres to depict the life of Artem Goriainov, a prisoner in the Solovki Islands labor camp in the late 1920s. The Monastery purports to be based on the reminiscences of the author’s great-grandfather, yet the narrative’s subtle structure and references to artistry reveal that the author’s representation of material is more important than the factual recording of events.

    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.

    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 Fiction2014In: Slovo: Journal of Slavic Languages, Literatures and Cultures , ISSN 2001-7395, Vol. 55, p. 60-76Article in journal (Refereed)
    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.

    Blood flow and cell transport in arteries and medical assist devices2018Doctoral thesis, comprehensive summary (Other academic)
    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 Olympics2018In: Diagoras: International Academic Journal on Olympic Studies, Vol. 2, p. 103-122Article in journal (Refereed)
    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.

    National injury prevention measures in team sports should focus on knee, head, and severe upper limb injuries.2018In: Knee Surgery, Sports Traumatology, Arthroscopy, ISSN 0942-2056, E-ISSN 1433-7347Article in journal (Refereed)
    Abstract [en]

    PURPOSE: To examine acute injuries in licensed floorball, football, handball, and ice hockey players in all ages nationwide in Sweden, and to identify the most common and severe injuries in each body location and recommend injury prevention measures.

    METHODS: Using national sport insurance data from years 2006-2015 was the incidence and proportion of acute injuries, and injuries leading to permanent medical impairment (PMI), calculated in the four team sports. The most common injury type and injured body part was identified, with a particular focus of the severe injuries. Comparison between sexes was made.

    RESULTS: In total, there were 92,162 registered injuries in all sports together. Knee injuries were most common, and also had the highest incidence of PMI, in all ball sports and in female ice hockey players. In male ice hockey, the most common injury was a dental and face injury, and PMI injuries were mostly in the shoulder. The most severe PMI injuries were rare and most often a face/eye injury in male floorball and ice hockey, a concussion in female ice hockey, and a knee injury in female floorball, and in both sexes in football and handball.

    CONCLUSIONS: To achieve the greatest impact in reducing the adverse effects of acute sport injuries nationwide in Sweden, preventive measures should focus on knee injuries in all the investigated team sports. The severe head/face and upper limb injuries also need attention. Protective equipment, neuromuscular training programs, rules enforcements, and fair-play interventions may reduce the incidence of injuries.

    Qualifying Standpoints: Stance adverbs as a presentational device for managing the burden of proof2009Doctoral thesis, monograph (Other academic)
    Abstract [en]

    A number of studies from pragmatics and discourse analysis have investigated the function of stance adverbs, such as clearly, fortunately, frankly, perhaps, and technically, when used to qualify utterances. Within the field of argumentation studies, scholars who have paid attention to these words have primarily focused on the so-called modal adverbs, and have not considered the insights that can be gained by treating the class of stance adverbs as the linguistic realisation of a certain move in an argumentative discussion. This study aims to fill this gap by investigating the strategic function of stance adverbs when qualifying an utterance that functions as a standpoint. In this study, stance adverbs are examined as a presentational device at the arguer’s disposal when putting forward a standpoint. The study is comprised of three parts. In the first part, the question ‘What is a qualified standpoint?’ is answered by combining illocutionary analysis of the move of advancing a standpoint with pragma-linguistic study of stance ad­verbs. In the second part, the question ‘Why would the protagonist qualify the standpoint?’ is answered based on the concept of burden of proof, which is es­sential to the move of advancing a standpoint. In the third part, the question ‘How does standpoint qualification function strategically in an argumentative discussion?’ is answered by postulating that the protagonist of a qualified standpoint is interested in managing the burden of proof, an assumption which builds on the results of the other two parts. The book is of interest to advanced students and scholars of argumentation and communication studies as well as those interested in an explanation of language use from an argumentative perspective.

    Antenna Limitations and Q-factor Trade-off between Parameters, Steps towards Optimal Antenna Design2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Sub-wavelength antennas have become ubiquitous in essential devices, such as mobile phones, sensors, Internet of things (IoT) and machine to machine (M2M) communication devices. Such antennas are often embedded as a small part of the device chassis or their circuit-boards. The size assigned both to the antennas as well as the device tends to shrink, while demands on antenna performance are increasing. In such a context knowledge of optimal performance is of increasing importance. The subject of this thesis is on the bounds of small antennas, in particular bounds on impedance bandwidth performance.

    The main tool to obtain bounds is antenna current optimization. The bounds are mainly focused on determining limits on the Q-factor for small antennas, and hence implicitly on the available bandwidth at a given reflection coefficient. We investigate Q-factor bounds under a number of constraints including directivity, far-field radiation pattern, efficiency, and the embedded position of the antenna. In this process, we combine physical methods, mathematical tools, and antenna engineering. We use the Method of Moments (MoM) approach to solving the Electric Field Integral Equations (EFIE), in this context we formulate and solve antenna optimization problems where the surface current density is an unknown variable, and we solve convex and non-convex quadratically constrained quadratic programs (QCQPs). For non-convex problems, we investigate different methods to obtain the solution, but with the main focus on the semidefinite relaxation (SDR) technique. Different current optimization problems are solved for a range of shapes, where the Q-factor and the optimal surface current are determined; the results are compared with full-wave-simulation of antennas that approach the bounds.

    To determine the Q-factor for an available space in the device is here proposed to be an initial step of an antenna design procedure. The current optimization helps us to determine the optimal trade-off between the different performance parameters of a small antenna, and it can inspire antenna design with better performance. We furthermore show that a multi-position feeding strategy to realize an optimal current successfully realize a non-standard far-field performance. As an example, we show that the desired radiation patterns are obtained with small costs of Q-factor. The thesis ends with a discussion of initial steps to a methodology with the goal of obtaining a Q-factor optimal antenna. Here the current optimization plays an important role in the antenna synthesis and analysis stages of the process. An application to the embedded antenna is discussed in detail.

    Intraspecific diversity of pike (Esox lucius) in the Baltic Sea and new insights on thermoregulation in fish2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Fish display a fascinating variation in behavior, morphology and physiology among species, among individuals within species, and within individuals over time. A central quest in ecology and evolution is to understand causes and consequences of such variation. This thesis aims to contribute to this knowledge by: (1) investigating the evolutionary processes that shape intraspecific variation among sympatric subpopulations of pike in coastal areas of the Baltic Sea; and (2) exploring whether fish can utilize sun-basking to regulate body temperature and whether this has any consequences for fitness.

    Identifying barriers that delineate populations is a first step towards evaluating the evolutionary origin of intraspecific variation. This thesis reports on genetic population structures among co-existing pike in the coastal Baltic Sea separated by homing behavior, different spawning strategies and geographic barriers. Field studies revealed that these subpopulations also show phenotypic divergence in reproductive and meristic traits. Experimental studies suggested that differentiation among subpopulations likely was a result of divergent selection and local adaptations to spawning grounds. These adaptations that may further reinforce barriers among subpopulations due to a reduced success of immigrant genotypes.

    For the second aim of the thesis, we first studied seasonal and diel patterns of activity and vertical migration among the Baltic Sea pike. The results suggested that pike exposed themselves to sunlight during spring and summer, and that body temperatures were positively correlated with sun exposure during these basking events. This was followed by experimental studies on inanimate physical models and a field study on carp which demonstrated that fish can become warmer than ambient water when exposed to sun light, a previously overlooked mechanism for fish thermoregulation, and that the heat gain was positively correlated with growth.

    This thesis contributes to our understanding of the origin and maintenance of intraspecific variation among coexisting populations with direct implications for management of pike. It also establishes sun-basking as a novel mechanism for fish to obtain body temperatures in excess of ambient water which could motivate adaptations, both evolutionary and plastic, that optimize heat gain, affect spatiotemporal distributions and biotic interaction within and among species.

    Elstation Stockholm C: användares erfarenheter2018Report (Other academic)
    Abstract [en]

    Current discussions concerning the development of sustainable transport often focus on the importance of shared and combined mobility options. In recent years, various types of initiatives have been launched with the intention of promoting the development of such ideas. Urban carpools are one such mode of transport and in Stockholm the electric carpool parking station, directly adjacent to Stockholm’s central train station, has been used as a parking and charging location for the collection and drop-off of both “fixed” and “floating” carpool vehicles during the period October 2016 to December 2017.

    One question of specific importance is how carpools are perceived by users when trying to understand the role this type of initiative plays in achieving sustainable mobility. This report presents the results of a focus group interview study conducted with a selection of people who have used various carpool services at the Stockholm Central electric carpool station.

    The purpose of the study was to gain a deeper the insight into the users' perspectives and experiences of carpool services in general, and more specifically how they experienced the electric carpool station at Stockholm’s Central station.

    The results from this study confirm a common aim for the development of carpool services, namely that this type of service should allow people to refrain from owning a car. However, our material also indicates that there are still practical barriers that make it difficult for specific groups to use a carpool, such as families with small children. These practical challenges need to be developed and overcome in order to encourage increased usage of carpools and car sharing services.

    Seismicity and crustal structure in Iceland2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The main goal of this Ph.D. thesis is to improve locations of earthquake hypocenters and to resolve heterogeneous crustal structure and its effects on travel times. The data and case studies are drawn from the Icelandic national SIL network and the temporary NICE project deploy-ment in the Tjörnes Fracture Zone. Iceland presents complex tectonics and active volcanism, consequences of its position astride the Mid-Atlantic Ridge between the European and North American plates and on top of a melting anomaly in the mantle below. Studies focused on characterizing the seismicity and the crustal structure are prerequisites for further seismologi-cal studies in Iceland, e.g., on seismic sources, the evolution of volcanic systems, activity on seismic faults and seismic hazard, among others.

    Different methods have been explored. First, we estimated empirically travel-time functions of seismic waves and their uncertainties for 65 stations in the Icelandic permanent network (SIL) using arrival times. The estimated travel-time functions and uncertainties were used to relocate the complete catalog applying a nested-search algorithm to this non-linear problem. The clearest changes in locations compared to the SIL solutions were obtained in the peripheral areas of the network, in particular in the Tjörnes Fracture Zone (North Iceland) and on the Reykjanes Peninsula (South Iceland).

    Relocations with empirical travel times were used complementary with constrained earth-quake relocation and the collapsing methods of Li et al. [2016] to study the seismicity in the Hengill area (South Iceland). Patterns in the seismicity in the final locations reproduce lin-eations previously found in relative relocations in the area. The brittle-ductile transition was estimated, obtaining a smaller depth in the northern part of the region, dominated by volcanic processes, compared with the south, controlled by tectonic processes. Furthermore, the Hengill fissure swarm that hosts two large geothermal power plants, was found to have deeper penetrat-ing earthquakes than adjacent volcanic areas, presumably because it is more effectively cooled.

    Local earthquake tomography was used to solve simultaneously for earthquake location and velocity structure in the Tjörnes Fracture Zone, using data from the temporary network installed during the North ICeland Experiment, and data from the permanent SIL network. 3-D velocity models for P- and S-waves were obtained for the area and used to relocate the complete SIL catalog. The results demonstrate significant structures associated with the different branches of this complex transform region, e.g. low velocities along the Husavík-Flatey Fault (HFF), penetrating to about 10 km depth. Low Vp/Vs ratios were also mapped at depth along the HFF indicating presence of highly compressible fluids in the middle crust. In general, the seismicity pattern was shifted towards the surface from SIL locations and clarified in its lateral distribution. This highlighted a zone of concentrated deformation in the Tjörnes Microplate, which intersections with the two main strands of the overall zone coincide with changes in their geometry and character.

    Crafting Lutheran Pastors in Tanzania: Perceptions of Theological Education and Formation in the Evangelical Lutheran Church in Tanzania2018Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The quest for theological education is embedded in the history of the churches in sub-Saharan Africa and is, at the same time, inherently linked to how the churches continue to evolve and shift in character over time. It relates to the self-understanding of the churches and their role in society, including their academic and pastoral obligations to adequately educate and train leaders to work in the localities. With its estimated 6.5 million members, the Evangelical Lutheran Church in Tanzania (ELCT) is today one of the largest Lutheran churches in the world. The role and impact of institutions for theological education are high on the agenda in the ELCT, not least as the various educational institutions for ministerial training are often seen as important means in the processes of theologising and strategising for the future.

    This qualitative study draws heavily upon interviews with Lutheran bishops and theological educators in Tanzania, and identifies leading motives and ideas behind their current engagements in the field of ministerial studies. More specifically, it shows how the informants reflect upon, argue about and negotiate their perceptions of higher theological education. It demonstrates by what means, techniques, and practices they claim to govern, guide, and form the students in theology. Formal ministerial studies are not carried out in a vacuum but in and through certain institutions, appropriately designed to serve their purposes. In order to gain academic accreditation, institutional and theological recognition, and to oversee the processes of quality assurance, the ELCT cultivates its links with relevant actors and institutions in Tanzanian society. Even the global networks and connections, such as other churches and missionary organisations abroad, play a significant role in this regard.

    Drawing inspiration from governmentality studies and the notion of governmentality, this study focuses on ‘how’ questions; it examines how the interviewees think about governing, and how they calculate, strategise, or respond to certain problems linked to the multiple forms and models of theological training. As such, the study focuses on how government operates, and examines what claims, hopes, and visions the informants have in mind when educating a new generation of clergy in a rapidly changing society.

    Recovery of Rare Earth Elements from an Apatite Concentrate2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Rare earth elements (REE) are a group of 17 elements including lanthanides, yttrium and scandium; which are found in a variety of classes of minerals worldwide. The criticality of the application, lack of high grade and economically feasible REE resources and a monopolistic supply situation has raised significant attention in recovery of these metals from low grade ores and waste materials. In this thesis, the recovery of REE from an apatite concentrate, containing 0.5 mass% of REE, within the nitrophosphate route of fertilizer production has been investigated. Most of the REE (≥ 95%) content can be recovered into a phosphate precipitate with almost 30 mass% REE. Different processes have been developed to convert the REE phosphate precipitate into a more soluble form to obtain a solution suitable for further REE purification and individual separation. It has been shown that after reprecipitation of the REE phosphate concentrate as REE sodium double sulphate and then transformation into a REE hydroxide concentrate, a solution containing 45g/L REE free of Ca, Fe and P can be obtained. The results suggest that the apatite waste after processing of iron ore have the potential to be a very important source for REE in Europe and that the economy is strongly supported by the simultaneous extraction of phosphorous.

    The potential of using hollow fiber supported liquid membrane (HFSLM) extraction in individual and group separation of REE has been investigated. A hollow fiber supported liquid membrane plant in pilot scale has been operated according to the three main configurations: standard hollow fiber supported liquid membrane technology (HFSLM); hollow fiber renewal liquid membrane technology (HFRSLM) and emulsion pertraction technology (EPT). The standard HFSLM operation is more selective than HFRSLM and EPT, while higher metal transport rate is observed in EPT followed by HFRSLM and HFSLM. The HFRLM configuration helps to maintain the performance of the liquid membrane.

    An evaluation of regional sustainability by analysing energy and carbon flows – A study of Jämtland, Sweden2018Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Models showing the anthropogenic and natural flows of two sustainability indicators; carbon based GHG and energy (as work energy) have been made for the Swedish region Jämtland. The methodology used was inspired by the study sustainability analysis conducted on the small Danish island Samsø using the above two indicators. The aim was to upscale the methodology used for Samsø and make necessary adaptations for Jämtland in order to be able to evaluate sustainability in terms of global warming. We also wanted to study the linkages between research, education and regional sustainability initiatives. Working at a regional level has advantages compared to working at a national or global level, as socio-ecological processes can be covered more extensively to reach a deeper understanding of practical aspects. In parallel to this we have also been participating in local and regional sustainability activities to increase our understanding of practical approaches and human behaviour.

    Studies of the energy flows in Jämtland show that 46,000 TJ (88% renewable) flows into the region and about 31,000 TJ is exported. The remaining 15,000 TJ (63% renewable) drives ‘the machine Jämtland’. Added to this is about 4000TJ as matter. The total global warming potential (GWP20) impact of Jämtland (as carbon dioxide equivalents, CO 2eq ) indicating influence on the global mean temperature as radiative forcing) is an annual uptake of 2.4 Mton. The total regional emissions, as CO 2eq, from anthropogenic activities, including consumption, are 1500 kton. The region has large emissions of methane, 80kton (6700 kton CO 2eq ), mainly from mires, lakes and animals but also large uptakes of CO2 from assimilation in woody biomass.

    Jämtland can be regarded as relatively sustainable from several perspectives, but taking the large forests and a population of only 127,000 inhabitants into consideration, the total uptake of CO 2eq is not very large and of the 15,000 TJ driving Jämtland, 37% comes from non-renewable sources. From a national (and global) perspective Jämtland needs to perform better, in view of its considerable reserves of natural resources. How to increase long-term sustainability in the region is a complex issue that requires penetration from many perspectives. Modelling results presented here needs to be interpreted in a broader sustainability context, together with regional stakeholders, to serve as a base for future knowledge development and sustainability activities.

    The Greek noun ekphrasis is connected to the verb ekphrazein, which means ‘to speak out’, or ‘tell in full’. Jean Hagstrum and other influential critics define this term as a special quality of giving voice and language to otherwise mute artworks. The aim of this article is to discuss and interpret the theoretical views concerning ekphrasis formulated by Jean Hagstrum, John Hollander, James A. W. Heffernan, and W. J. T. Mitchell. It also comprises a practical application of these theoretical postulates. Poems which actualize the ekphrastic principle, defined as “to give a voice to mute artworks,” are considered in light of theoretical considerations.

    Wireless Communication Networks for Time-critical Industrial Applications2018Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Wireless communication is of paramount importance to enable the vision of Industry 4.0. Compared to mobile communications, industrial communications pose demanding requirements in terms of ultra low latency and high reliability. Currently, for the most time-critical industrial applications, there is no available wireless solutions satisfying these latency requirements. This thesis studies effective techniques to reduce the latency for the time-critical industrial applications, especially from the Physical Layer (PHY) point of view.

    The thesis is organized in two main parts. In the first part, the available methods for low latency are surveyed and analyzed in terms of end-to-end latency. It is argued that the enabling techniques should be optimized together to reduce the end-to-end latency while satisfying other requirements such as reliability and throughput. Moreover, the realistic timing constraints of different PHY algorithms, hardware, and mechanisms are derived based on the state-of-art wireless implementations. In the second part, a revision of PHY with an optimized PHY structure is proposed to reduce the latency. It is shown that a PHY with just a short one-symbol preamble and dedicated packet detection and synchronization algorithms for short packets is robust to carrier frequency offsets and false alarms by both theoretical and site experiments.

    The investigations of this thesis show that revising the PHY structure/parameters is effective to reduce the packet transmission time, and further improve the latency performance of wireless communication network for time-critical industrial applications. In the future, we include the PHY results of this thesis in the investigation of the Medium Access Control (MAC), for industrial wireless communications with very low latencies.

    Architectures of Life-Building in the Twentieth Century: Russia, Germany, Sweden2018Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The modernist concept of life-building as an architectural method for improving the conditions of everyday life originated in Europe during the 1920s. This book explores three modes of functionalism by way of a comparative analysis of both the theoretical discourses and architectural practices associated with functionalism in Russia, Germany, and Sweden. These three countries made significant contributions to the application of functionalism within mass housing construction, the overarching purpose of which was to transform the traditional home into a rational living space.

    This study provides both close readings of foundational modernist texts as well as an empirical study of the avant-garde heritage in Russia, Germany, and Sweden. As a special case study, a visual analysis of IKEA catalogues is presented, the purpose of which is to provide an illustrated history of modernist aesthetics within mass-produced living spaces, from the era of functionalism up to the present day.

    Abstract [en]

    The aim of this paper is to examine primarily Croatian, but also Bosnian and Serbian media and literary discourse on representations of Scandinavia as a constructed sociocultural space. Analysis of media discourse was conducted by examining journalistic texts published on various web portals over the past few years. The majority of these representations are very positive, constructing Scandinavia as a social utopia. I argue that these representations are more narratives that “we tell ourselves about ourselves” (Geertz) than objective reflections of reality. I discuss the importance of popular culture and brands in reinforcing positive representations. Furthermore, literary texts by A. Mešković, B. Sejranović and D. Špišić construct representations of Scandinavia from an immigrant perspective. These are potentially politically subversive because they address questions about the power of those in the position of the Other in Scandinavian societies.

    «... прошу не забыть, что есть у Вас друг»: Олаф Брок и Алексей Александрович Шахматов2015In: Slovo: Journal of Slavic Languages, Literatures and Cultures , ISSN 2001-7395, Vol. 56, p. 37-57Article in journal (Refereed)
    Abstract [en]

    The article “... please do not forget that you have a friend”: Olaf Broch and Aleksej Aleksandrovič Šachmatov is based on archivе materials containing hitherto unknown facts from the life of the Norwegian Slavist Olaf Broch. The article focuses primarily on aspects of Broch’s biography after the death of his colleague and friend, the Russian Academy member Aleksej Šachmatov. Fragments of the long-standing correspondence between Šachmatov's elder sister Evgeniya Masalskaya-Surina and Professor Broch are published here for the first time. The article concludes with the entire text of Olaf Broch’s “From the memories of A. A. Šachmatov.”

    O fonološkim i morfološkim osobitostima Habdelićeva Zrcala Marijanskoga (1662)2015In: Slovo: Journal of Slavic Languages, Literatures and Cultures , ISSN 2001-7395, Vol. 56, p. 24-36Article in journal (Refereed)
    Abstract [en]

    This article analyses the phonological and morphological features of Juraj Habdelić’s (1609–1678) work Zarczalo Marianzko (1662) in order to demonstrate that its language is predominantly based on the literary Croatian Kajkavian dialect. Moreover, the author sheds light on the impact of Štokavian and Čakavian authors on Habdelić's language. Special attention is paid to those language features which can be viewed as Kajkavian, but which were included in the body of literary Kajkavian as a whole at a time when the Kajkavian literary tradition still existed. The study shows that there were non-Kajkavian elements at a phonological level, such as the reflex of šva, denotation of syllabic r̥ as ar, reflex of *ď as đ, and the actualization of the Second Palatalisation of velars. As for morphology, the following features are encountered: voc. sg. m. - e, the interrogative-relative pronoun što including its derivatives, the use of the future tense, and the particle neka in the imperative 3. pers. sg. Of the overall Kajkavian dialectal features throughout its existence as a literary tradition, other divergences are also encountered: the change of e >, o loss of the negative form of the verb moći in 1. pers. pl., the forms of the numerals štiri and dvajseti, and the short, contracted forms of the perfective present tense form of the auxiliary verb biti.

    A Diachronic Study of the Dative in the Written Czech Language2015In: Slovo: Journal of Slavic Languages, Literatures and Cultures , ISSN 2001-7395, Vol. 56, p. 8-23Article in journal (Refereed)
    Abstract [en]

    The present paper deals with the study of the semantics of the dative case in the written Czech language from the point of view of cognitive semantics. Its aim is to apply the semantic configuration of the Czech dative – mainly provided by Janda’s A Geography of Case Semantics (1993) and Janda and Clancy’s The Case Book for Czech (2006) – to a large corpus composed of 8,355 datives belonging to four significant periods in the history of Czech written language: old Czech, middle Czech, new Czech, and contemporary Czech.
