    Evaluation of thresholds for capacities and pollutants according to the Protocol on PRTRs: Case-study for the Nordic countries2019Report (Other academic)
    Abstract [en]

    Based on experience gained from the implementation of the national PRTR (Pollutant Release and Transfer Register) registers parties to the Protocol on PRTRs shall consider evaluating the thresholds for capacities and pollutants listed in Annex I and II of the Protocol (Article 6 (2)). The thresholds were set aiming to cover about 90 % of industrial pollution in Europe.

    This case study for the Nordic countries aims to evaluate threshold values for capacity (Annex I) and substances (Annex II) according to the Protocol on PRTRs. The evaluation has been based on available data in the countries' national environmental reporting databases, European PRTR (E-PRTR) and, for emissions to air, data from CLRTAP (Convention on Long-Range Transboundary Air Pollution). A number of pollutants to air (NOX, SOX, NH3 and PM10) and to water (total nitrogen, total phosphorus, Pb and Hg) has been included in the analysis.

    When comparing at European level for all included air pollutants, the results show that E-PRTR data does not capture 90% of the corresponding industrial emissions according to CLRTAP. For all pollutants, removal of threshold values for pollutants would increase the coverage in relation to CLRTAP. However, for NH3 and PM10, the difference between E-PRTR data and CLRTAP data is very large and additional measures are required. For both pollutants is it obvious that livestock is the activity where the difference between E-PRTR and CLRTAP is the largest. This indicates that the PRTR capacity threshold for livestock should be reviewed and that there is a need to evaluate the calculation methodology of the EMEP/EEA Guidebook. For PM10, it can also be noted that Annex 4 of the E-PRTR guidance document should be updated, as PM10 is not included since it is not expected to be emitted from livestock.

    For emissions to water, no dataset corresponding to CLRTAP exists, therefore any comparison on European level could not be made. Consequently, comparisons for water can only be made between two datasets, data reported to the national environmental reporting databases and to E-PRTR. For Pb, removing the threshold is enough to capture 90% of the reported emissions in the national reporting databases. For the remaining substances, however, additional measures are required to increase the coverage in relation to the national databases. Wastewater treatment plants and aquaculture are the industries that have been identified as the most relevant for a review of the capacity thresholds.

    Courses for tutors in problem-based learning. Current challenges at four Swedish universities2015In: Högre Utbildning, ISSN 2000-7558, E-ISSN 2000-7558, Vol. 5, no 1, p. 47-64Article in journal (Other academic)
    Abstract [en]

    The key role of the tutor in problem-based learning (PBL) is to help students become selfregulated learners. Tutors need training to acquire the necessary facilitating skills for this task. The aim of this article is to describe and discuss how PBL tutor training is currently arranged at four universities in Sweden: Linköping University, Lund Medical Faculty, Uppsala Medical School and Örebro School of Medicine. Moreover, we seek to analyse how the content and format of the tutor training courses correspond to the desired skills and competencies for PBL tutors described in the literature. We draw especially on work coming out of three pioneering universities for PBL: McMaster University, Canada; Maastricht University, The Netherlands; and Linköping University, Sweden. One aim has been to construct a framework for analysis that uses categories specifying the knowledge base, capabilities and skills to support students’ learning processes which characterise the full-fledged PBL tutor. For this framework, we have used the following categories: Knowledge of PBL and pedagogical theories, Personal traits, Student-centeredness, Ability to handle group processes, and Subject knowledge. We collected descriptions of the course design and content from the four universities, and assessed to what extent these categories were represented within the courses. Our results show that all categories inform the course content at all four universities, though the design varies between courses. In summary, we show that the four PBL tutor training courses are all designed to enable participants to experience PBL first-hand both as members of a tutorial group and as tutors. They all also include a theoretical base and offer opportunities for discussion and reflection with peers; however, there are some differences in design between the courses. According to participants, all four courses provide good preparation for the tutor role. Yet, we see a need for the programmes to organise continuous educational support for tutors after they have started their work with groups of students.

    Föreningsidrottens politiska och demokratiska samband2016In: Föreningen, laget och jaget: 7 perspektiv på idrottens demokratiska effekter / [ed] Christine Dartsch, Johan R Norberg och Johan Pihlblad, Stockholm: Centrum för Idrottsforskning , 2016, p. 47-58Chapter in book (Other academic)
    Abstract [sv]

    Ungefär 30 procent av Sveriges vuxna befolkning är medlemmar i idrottsföreningar. 29 Kan personer som är aktiva inom föreningslivet bidra till en bättre demokrati? Vid en första anblick kan sambandet verka långsökt. Varför skulle opolitiska föreningar ha någon demokratisk betydelse?

    I det här kapitlet undersöker jag om engagemang inom idrottens organisationer bidrar till ökat politiskt deltagande. Vidare granskas i vilken utsträckning organisationerna kontaktar beslutsfattare i syfte att försöka påverka dem i frågor som rör organisationerna. Detta görs i två steg och med hjälp av två enkäter. Den ena är riktad till ett slumpmässigt urval av den svenska befolkningen för att kartlägga det ideella arbetet i Sverige. Den andra är i sin tur riktad till ett slumpmässigt urval av ideella föreningar runtom i landet.

    Use of X-ray Micro-computed Tomography (µCT) for 3-D Ore Characterization: A Turning Point in Process Mineralogy2019Conference paper (Refereed)
    Abstract [en]

    In recent years, automated mineralogy has become an essential enabling technology in the field of process mineralogy, allowing better understanding between mineralogy and the beneficiation process. Recent developments in X-ray micro-computed tomography (μCT) as a non-destructive technique have indicated great potential to become the next automated mineralogy technique. μCT’s main advantage lies in its ability to allow 3-D monitoring of internal structure of the ore at resolutions down to a few hundred nanometers, thereby eliminating the stereological error encountered in conventional 2-D analysis. Driven by the technological and computational progress, the technique is continuously developing as an analysis tool in ore characterization and subsequently it foreseen thatμCT will become an indispensable technique in the field of process mineralogy. Although several software tools have been developed for processing μCT dataset, but the main challenge in μCT data analysis remains in the mineralogical analysis, where μCT data often lacks contrast between mineral phases, making segmentation difficult. In this paper, an overview of some current applications of μCT in ore characterization is reviewed, alongside with it potential implications to process mineralogy. It also describes the current limitations of its application and concludes with outlook on the future development of 3-D ore characterization.

    Kontakter mellan grupper inom civilsamhällets organisationer2018In: Socialmedicinsk Tidskrift, ISSN 0037-833X, Vol. 95, no 5, p. 528-538Article in journal (Refereed)
    Abstract [sv]

    Studien undersöker i vilken mån det förekommer kontakter mellan grupper som är olika varandra eller inte inom civilsamhällets organisationer och nätverk och om kontakterna samvarierar med lägre fördomar och högre tillit till grupper som är annorlunda en själv. Studien är baserad på en surveyundersökning som är genomförd till ett urval av invånare mellan 18-84 år i 36 svenska kommuner. Totalt deltog drygt 10200 personer i undersökningen. I takt med att mångfalden i samhället ökar framställs arenor som möjliggör kontakter mellan grupper alltmer centrala för den sociala sammanhållningen. Flera tidigare studier pekar på samband mellan exempelvis tillit och ökad livskvalitet, bättre självskattad hälsa. Kontakter mellan grupper inom ramen för civilsamhället förekommer i varierande utsträckning mellan typ av organisationer och kommuner. Resultaten pekar på betydelsen av att kontakterna uppfattas som positiva för tillit och tolerans mellan grupper. Resultaten är i linje med tidigare studier på att yngre är mer benägna att uppfatta kontakter som positiva än äldre.

    The evolution of sex chromosomes and sex-linked sequences in birds2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Identifying the processes involved in the evolution of suppressed recombination between sex chromosomes and understanding their consequences for the evolutionary dynamics of sex-linked loci have been major topics of research during the last century. In this thesis, I used the avian ZW system, where females are the heterogametic sex, to investigate the underlying processes in sex chromosome evolution in birds. I identified the gametologous genes between the largely recombining Z and W chromosomes of ostrich and dated the timing of the cessation of recombination to prior to the split of modern birds. I then constructed a genetic map of the ostrich Z chromosome and corrected its assembly in order to obtain the ancestral organization of the Z chromosome in a basal clade of birds. By analyzing the inversion events across the avian phylogeny, I concluded that a combination of Z- and possibly W-linked inversions might have been responsible for the evolution of suppressed recombination in avian sex chromosomes. To understand the determinants of levels of genetic diversity on Z chromosome compared to autosomes, I calculated Z to autosome (Z:A) genetic diversity across 32 avian species. This revealed a broad range of Z:A genetic diversity, between 0.278 – 1.27. Lineage-specific estimates of the nonsynonymous to synonymous substitution rate ratio (dN:dS) for autosomal and Z-linked genes further revealed a Fast-Z effect in the majority of birds. The lack of a significant correlation between Z:A dN:dS and Z:A genetic diversity indicated that genetic drift might not be sufficient to explain faster evolution of Z-linked genes, suggesting that positive selection might also contribute to the observed values. Finally, I calculated genetic diversity and linkage disequilibrium (LD) along the pseudoautosomal region (PAR) of the Z chromosome using population genomics data of ostrich. In contrast to theoretical expectation, levels of diversity on the PAR were not significantly higher close to the sex-determining region (SDR) compared to autosomal values. Additionally, I observed a lower level of LD on the PAR compared to the average for the Z chromosome and no significant level of LD across the PAR boundary was detected, indicating recombination allows the boundary-proximal region of PAR to behave independently of SDR. Considered together with a higher level of recombination rate in females in the proximity of the SDR, this observation might help explain the maintenance of a long PAR in ostriches and other ratites. Altogether, the results of this thesis make a modest contribution to our understanding of sex chromosome evolution in birds.

    Probing Catalytic Reaction Mechanisms of Biomimetic Diiron Complexes through Time-resolved Absorption Spectroscopy2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Directed design of improved molecular catalysts for hydrogen evolution reactions relies on rational benchmarking based on a 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 coordination geometry, but show different structural rearrangements upon reduction. This could be applied to rationalize their differences in protonation dynamics. Protonation kinetics of singly reduced species, forming a 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 the 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 a proton shuttle in the hydride formation in the FeIFe0 state. Instead, the effect of nitrogen protonation is to lower the catalyst overpotential, without substantially slowing down the hydride formation with external protons. The amine acting as a proton shuttle in the hydride formation could be expected in the Fe0Fe0 level. However, slower second reduction of FeIFeI (S-azapropyl-S)(CO)6 complex impedes observation of the doubly reduced species under the catalytic conditions. For the benzyldithiolate complex, on the other hand, the rigid and unsaturated bridging ligand generally leads to less negative potentials and prevent the reduced forms from rapid degradation. This allows characterization of the later intermediates of the catalytic processes, and to obtain direct kinetic information on the turnover step.

    Assembly and Function of Nitric Oxide Reductase from Paracoccus denitrificans2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Bacterial denitrification is a part of the global nitrogen cycle and comprises the stepwise reduction of nitrate to molecular nitrogen, which is released to the atmosphere. Cytochrome c-dependent nitric oxide reductase (cNOR) from Paracoccus (P.) denitrificans catalyzes the reduction of nitric oxide to nitrous oxide and water. This is a key step of the denitrification chain as it involves reformation of the N-N bond that was split in nitrogen fixation processes. In addition, nitric oxide is cytotoxic and nitrous oxide is a potent greenhouse gas. cNOR is an integral, two-subunit membrane protein, which contains several redox-active metal cofactors essential for function. In P. denitrificans the enzyme is expressed from an operon norCBQDEF, of which only norCB are the structural genes for the cNOR protein. The assembly process of cNOR, including cofactor insertion, as well as the detailed catalytic function of the enzyme are largely unknown, which motivated this study.

    Our results showed that cNOR can be expressed from only the norCB genes and that norQDEF are not essential for folding, complex formation and heme cofactor assembly of the protein. However, we found that non-heme iron (FeB) cofactor insertion into cNOR was dependent on the NorQ and NorD proteins, which were expressed from the nor operon. These proteins were purified as a complex and our results indicate that they act as a molecular chaperone. We present the cryo-electron microscopy structure of NorQ, which formed hexameric ring-shaped oligomers and was shown to have ATPase activity. Our data further suggest that NorD functions as an adaptor protein in order to link NorQ to a specific binding site at the cytoplasmic surface of cNOR. Based on our experimental data we present a model for FeB cofactor insertion into cNOR.

    Without co-expression of the NorQ and NorD proteins, the produced cNOR was inactive. It lacked FeB at the catalytic center but was otherwise structurally intact. Therefore we used this protein to investigate the role of FeB in the mechanism of nitric oxide and oxygen reduction of cNOR and compared our results to computational studies of the enzyme published recently.

    In vitro studies of membrane proteins, such as cNOR, are challenging because their function often depends on the interaction with a biological membrane and specific phospholipids. We used two different membrane mimetic systems, lipid nanodiscs and proteoliposomes, to study the effect of a membrane environment on the function of detergent-solubilized cNOR. Our results indicate that the membrane bilayer of lipid nanodiscs and proteoliposomes, even when assembled using the same lipids, has different properties with measurable effects on cNOR function.

    Stochastic epidemics on random networks2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis considers stochastic epidemic models for the spread of epidemics in structured populations. The asymptotic behaviour of the models is analysed by using branching process approximations. The thesis contains four manuscripts.

    Paper I is concerned with the study of the spread of sexually transmitted infections, or any other infectious diseases on a dynamic network. The model we investigate is about the spread of an SI (Susceptible → Infectious) type infectious disease in a population where partnerships are dynamic. We derive explicit formulas for the probability of extinction and the threshold parameter R0 using two branching process approximations for the model. In the first approximation some dependencies between infected individuals are ignored while the second branching process approximation is asymptotically exact and only defined if every individual in the population can have at most one partner at a time. By comparing the two approximations, we show that ignoring subtle dependencies in the dynamic epidemic model leads to wrong prediction of the probability of a large outbreak.

    In paper II, we study a stochastic SIR (Susceptible → Infectious → Removed) epidemic model for the spread of an epidemic in populations structured through configuration model random graphs. We study the asymptotic (properly scaled) time until the end of an epidemic. This paper heavily relies on the theory of branching processes in continuous time.

    In paper III, the effect of vaccination strategies on the duration of an epidemic in a large population is investigated. We consider three vaccination strategies: uniform vaccination, leaky vaccination and acquaintance vaccination.

    In paper IV, we present a stochastic model for two successive SIR epidemics in the same network structured population. Individuals infected during the first epidemic might have (partial) immunity for the second one. The first epidemic is analysed through a bond percolation model, while the second epidemic is approximated by a three-type branching process in which the types of individuals depend on their status in the percolation clusters used for the analysis of the first epidemic. This branching process approximation enables us to calculate a threshold parameter and the probability of a large outbreak for the second epidemic. We use two special cases of acquired immunity for further evaluation.

    The Effect of Enzymatic Digestion on Cultured Epithelial Autografts2019In: Cell Transplantation, ISSN 0963-6897, E-ISSN 1555-3892Article in journal (Refereed)
    Abstract [en]

    Severe burns are often treated by means of autologous skin grafts, preferably following early excision of the burnt tissue. In the case of, for example, a large surface trauma, autologous skin cells can be expanded in vitro prior to transplantation to facilitate the treatment when insufficient uninjured skin is a limitation. In this study we have analyzed the impact of the enzyme (trypsin or accutase) used for cell dissociation and the incubation time on cell viability and expansion potential, as well as expression of cell surface markers indicative of stemness. Skin was collected from five individuals undergoing abdominal reduction surgery and the epidermal compartment was digested in either trypsin or accutase. Trypsin generally generated more cells than accutase and with higher viability; however, after 7 days of subsequent culture, accutase-digested samples tended to have a higher cell count than trypsin, although the differences were not significant. No significant difference was found between the enzymes in median fluorescence intensity of the analyzed stem cell markers; however, accutase digestion generated significantly higher levels of CD117- and CD49f-positive cells, but only in the 5 h digestion group. In conclusion, digestion time appeared to affect the isolated cells more than the choice of enzyme.

    Work hardening during alternating load directions of 316L SS2018In: Procedia Manufacturing, E-ISSN 2351-9789, Vol. 15, p. 1777-1784Article in journal (Refereed)
    Abstract [en]

    Understanding and modelling the plastic behavior of a material are essential for simulation and design of metal forming processes. Cold pilgering of tubes is a process with very complex strain history with alternating loading direction. This makes evaluation of the work hardening challenging. Cold deformation applied in a single direction predominantly exhibit work hardening, while changes of the loading direction may even cause softening in other directions. The influence of alternating loading directions on work hardening has been experimentally investigated for 316L stainless steel (SS). Cubic specimens were cut out from the preform of the tube. The specimens are subjected to uniaxial compressions in alternating directions along two perpendicular axes. From the results, a cyclic elastic-plastic constitutive model based on a Chaboche-type approach is calibrated and implemented in the commercial finite element code MSC.Marc.

    Numerical study on inertial effects on liquid-vapor flow using lattice Boltzmann method2019In: Energy Procedia, ISSN 1876-6102, E-ISSN 1876-6102, Vol. 160, p. 428-435Article in journal (Refereed)
    Abstract [en]

    Liquid-vapor flow in porous media is studied in this article. To fulfill this goal, a double-distribution-function lattice Boltzmann (LB) model is proposed based on the separate-phase governing equations at the representative elementary volume (REV) scale. Importantly, besides the Darcy force and capillary force, which were commonly included in previous studies, the LB model in this article also considers the inertial force characterized by the Forchheimer term. This feature enables the model to offer an effective description of liquid-vapor flow in porous media at low, intermediate and even high flow rates. We validated the LB model by simulating a single-phase flow in porous media driven by a pressure difference and found its results are in good agreement with the available analytical solutions. We then applied the model to study water-vapor flow in a semi-infinite porous region bounded by an impermeable and heated wall. The numerical simulation reveals the flow and mass transfer characteristics under the compounding effects of inertial, Darcy and capillary forces. Through a comparison with the results given by the generalized Darcy's law, our numerical results directly evidence that the inertial force is a dominating factor when a fluid passes through porous media at an intermediate or high flow rate.

    Life cycle assessment of building materials for a single-family house in Sweden2019In: Energy Procedia, ISSN 1876-6102, E-ISSN 1876-6102, Vol. 158, p. 3547-3552Article in journal (Refereed)
    Abstract [en]

    The Nordic countries have shown great interest in using Life Cycle Assessment (LCA) in the building sector compared to the past years. Sweden has set up an objective to be carbon neutral (no greenhouse gas emissions to the atmosphere) by 2045. This paper presents a case study of a single-family house “Dalarnas Villa” in the region Dalarna, Sweden within a 100-year perspective. The assessment is implemented using a new software based on hard data agreed by Environmental Product Declarations (EPDs). It focuses on building materials, transport distances of the materials, and replacement of essential construction materials. The LCA in this study demonstrates the environmental impact related to building materials from production and construction phase including transport, replacement and deconstruction phase. The study does not cover energy use and water consumption. The results show that the building slab made by concrete is the part of the construction most contributing to CO2e, while the wood frame and cellulose insulation have low environmental impact. Replacement of materials takes nearly half of total environmental impact over 100 years. Having a large share of wood-based products, make greenhouse gas emissions remains low.

    Rebalancing power relationships in research using visual mapping: examples from a project within an Indigenist research paradigm2019In: PRACTICE Contemporary Issues In Practitioner Education, ISSN 2578-3858, p. 1-9Article in journal (Refereed)
    Abstract [en]

    Engaging in respectful relationships is an essential aspect of all research and educational practices. Colonial residue, and the maltreatment and misinterpretation of Indigenous peoples by researchers, puts a great responsibility on the researcher to strive for balance in power relationships within Indigenous contexts. Even more so, in research and education involving Indigenous children diagnosed with autism spectrum disorder (ASD). This may be easier said than done. In a PhD project on the meaning of music for First Nations children diagnosed with ASD in British Columbia, Canada, visual mapping was used to rebalance the power relationships between myself as a researcher and the research partners as a step toward decolonization. The visual maps were used to summarize conversation transcripts that could be used to validate my interpretations and disseminate the research results, create a mutual focal point for negotiating consent and participation and show progress over time. Visual methods, such as visual mapping, are beneficial to individuals with autism, and can also be useful when rebalancing power relations with other research partners, such as parents. In conclusion, visual mapping can be a useful tool for rebalancing power relationships in research and educational practices.

    Individual Reflection Paper – Supporting Students’ Learning in the Critical Phase of Self-directed Learning in PBL2019In: Journal of Problem Based Learning in Higher Education, ISSN 2246-0918, E-ISSN 0974-276XArticle in journal (Refereed)
    Abstract [en]

    Supporting and assessment of students’ preparation and learning process in problem-based learning (PBL) tutorials has long been a challenge. We present a modified PBL model focussing on the specific critical phase in the PBL process, the self-directed learning phase in between tutorial meetings. The modified seven step PBL model including an Individual reflection paper (IRP) is presented as well as students’ perspectives on the implementation of IRP and information literacy, knowledge gathering, and PBL tutorial work. The assessment of PBL work is complex, and the ways in which IRPs support the tutor’s role as an examiner is beyond the scope of the current study. However, it seems that the students experienced assessment of the IRPs as part of their as a positive driving force in their learning process.

    Coloured BIPV : Market, Research and Development2019Report (Other academic)
    Abstract [en]

    In the building sector, net-zero energy performance targets and reduction of CO2 emissions are the main drivers for building integrated photovoltaics. Recent market studies [10,18,19] show the history and perspective of the global market in the BIPV sector and calculate a global compound annual growth rate of ~ 40 % from 2009 up to 2020.

    In Europe, the BIPV market is in a transition. The past decades of a slowly emerging BIPV market have been characterized by the original dominant value of BIPV: a building that communicates an image of sustainability and innovation. Payback time or "return on investment" have not been the major parameters in the decision process for applying BIPV. This is changing now. In most European countries, the new regulations on energy performance in buildings (derived from the European Energy Performance of Buildings Directive and the Directive on energy efficiency) have been translated in national regulations/laws, stating that all new (and freshly refurbished) buildings of the EU member states should be nearly zero energy buildings (nZEBs) by 2020. Thus, the time for the regulations to become mandatory is very near. It is expected that the energy performance regulations are now taking over as the main driving factor for the BIPV market and that should have huge consequences in removing the difference between a conventional building component and a BIPV component both in aesthetical and construction terms. This has led to intensified research and development aiming to create BIPV products that come in a variety of colours and sizes, while at the same time being as close as possible to existing building components, to its requirements and how it is considered by the construction industry.

    The given market overview of state-of-the-art coloured BIPV products clearly reveals that for all parts of a BIPV module (glass, polymers, PV-active layers), there are technical solutions available for colouring. Pilot projects utilizing coloured BIPV products have been built in numerous (mainly European) cities clearly demonstrating the maturity of these solutions.

    The key aspect that has been slowing down the progress of implementation of these aesthetically appealing and technically sophisticated new products into a wider market are the costs. In this respect, a lot of effort has been made to improve and optimize the relationship between colour and efficiency/power generation of BIPV elements. The results of the past and on-going innovative research and intensified fundamental considerations are also summarized in this report.

    Besides the colour perception of the coloured BIPV elements under solar irradiation which is essential for the acceptance of the exterior appearance of a building, also transparency and inside visual comfort of BIPV – windows and façade elements are essential for the users and inhabitants.

    Islam in Aru, Indonesia: Oral traditions and Islamisation processes from the early modern period to the present2019In: Indonesia and the Malay World, ISSN 1363-9811, E-ISSN 1469-8382Article in journal (Refereed)
    Abstract [en]

    The coming of Islam in eastern Indonesia is generally assigned to the activities of Muslim traders from the late 15th century onwards. This assumption is an over-simplification, especially in areas outside the main trade centres. In the Aru islands, Islam was introduced by the mid 17th century. We argue that Islamisation in Aru was initially a matter of internal considerations, rather than trade. We present oral traditions about the expansion of Islam as seen from two locations: Ujir, the historical Muslim centre in Aru on the west coast, and Benjuring, a former stronghold of local ancestral beliefs in the east. The oral sources are juxtaposed with European accounts of the 17th century when Muslim and Protestant centres first developed in Aru. The coming of Islam forced people to either convert or leave for non-Muslim areas. By late colonial times (early 20th century), both Islam and the Protestant church had reached remote villages. The most recent wave of conversions in Aru to state-approved world religions took place in the 1970s. In the last 30 years, the population in Aru has grown, especially in the regency capital Dobo. While Muslims used to be a small minority in Aru with their main centre on Ujir island, the point of gravity has shifted to Dobo, a fast-growing town with a large influx of mostly Muslims from other parts of Indonesia. Islamisation is still ongoing in Aru and the character of Islam is changing.

    Urban Heritage as a Generator of Landscapes: Building New Geographies from Post-Urban Decline in Detroit2018In: Urban Science, Vol. 2, no 3, p. 1-16, article id 92Article in journal (Refereed)
    Abstract [en]

    At this historical moment, the urban planning and design professions are confronted with the twin challenges of unprecedented rapid urbanization on the one hand, and declining post-industrial regions on the other. In this environment, there are many different and often conflicting ideas about urban heritage and its relevance for contemporary urban planning and design. In this paper, we look for commonalities and a way forward from among a range of competing urban design models. We examine the illustrative case study of the geography and landscape of Detroit, USA. We consider seven contemporary urban planning and design ideals that dominate the contemporary planning and design discourse and their different views of the past and urban heritage in relation to the approaches in Detroit. From these, we draw a synthesis approach, making several recommendations and observations with a focus on the capacities of so-called “placemaking” approaches. In this paper, urban heritage is understood and examined as contributing a pattern of infrastructure that provides a helpful supportive framework, and (importantly) a set of structural limitations (e.g., historic plot boundaries), that can serve as a generative resource for new urban planning and design. We conclude that the necessary framework for democratic participation and opportunity within urban space can be provided most directly by leveraging the assets of urban heritage.

    Between stability and contingency: A case study of the social, political and fantasmatic logics of Swedish history classroom practice2019In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2019:1, p. 132-155Article in journal (Refereed)
    Abstract [en]

    This study explores the political and ideological workings of history classroom practices enacted in the context of Swedish upper secondary education. Using the post-structuralist logics of critical explanation framework (Glynos & Howarth, 2007), the paper reports on a series of video-recorded observations and outlines the discursive logics found to constitute the studied practices. At the heart of the analysis are the socially shared assumptions, political relationships of us-and-them, and ideological narratives that alternately furnish the history classroom practices with stability and contingency. The results encompass three case-specific logics: (I) a social logic demonstrating that the stability of the studied classroom practices rests on shared assumptions about historical idealism and partial progress, (II) a political logic indicating that the classroom practices are unsettled when students establish temporal equivalence between past and present us-and-them relationships, and (III) a fantasmatic logic showing that teachers and students become ideologically invested in said practices through narratives emphasizing the need to prevent the repetition of past injustices.

    Students’ Understanding of Historical Sources – A Composite Ability2019In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2019:1, p. 105-131Article in journal (Refereed)
    Abstract [en]

    This paper investigates what students need to learn, to be able to interpret and evaluate sources, in relation to specific subject matter addressing Imperialism and Decolonization. The History-didactical framework used stems from the Historical Thinking tradition and the method applied is a textual analysis informed by theoretical assumptions originating from Variation theory. Data is derived from assignments generated in two Learning Studies undertaken in a Swedish upper secondary school. Specific aspects were identified as critical for our students’ ability to handle the sources in a composite manner. On a more general level results indicate that the application of source-criticism only in the form of source-critical criteria is not the ideal choice, since their design not necessarily seem to encourage students to interpret and evaluate sources from a composite standpoint. A proposal given is that the development of students’ ability to handle historical sources might benefit if Swedish history instruction adopted elements associated with the second order concept of evidence and allowed such practices to complement usage of  source-critical criteria.

    Flytande inflytande: Affektiva relationer mellan barn och miljön i förskolan2019Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The purpose of this doctoral thesis is to develop more understandings concerning children’s influence in preschool. By adopting an immanent approach the study centers on young children’s affective relations with the milieu in preschool.

    The empirical material was produced through approximately 30 hours of observations by video camera and field notes in a preschool department with children aged one to three years. Focus of the observations has been to follow the children in their everyday lives in preschool.

    The result shows three forms of influence characterized by four qualities. One quality is that influence is understood as collective. This means that the children’s relations always involves other actors, both human and non-human which produces an understanding of influence as fluent in the relations between different actors. Children’s relations also emerge through active affects with a creative quality to produce difference and alternatives. This produces an understanding of a child-influence. The result shows how the active intensity in child-influence also sometimes involves the pedagogues. Other affects that has emerged between the children and the milieu in preschool are the passive ones. These affects decreases the intensity and are characterized by acting as usual and according to routines. The pedagogues’ responses to the children’s relations are characterized by both a standardized response that points to a territorialization of earlier routines and the recognizable, and an affective attunement which emerge as a quality where the pedagogues’ tune in to the children’s affective relations. The affective attunement becomes a possibility for a togetherness-influence.

    The study concludes that instead of arranging certain situations where children verbally can express their opinions and take part in decision-making the influence of young children can be based on their bodily and affective relations with the milieu in preschool.

    Historical enquiry with archaeological artefacts in primary school2019In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2019:1, p. 78-104Article in journal (Refereed)
    Abstract [en]

    The article contributes with knowledge of primary school pupils’ learning of historical enquiry with an intercultural perspective on the Viking age and investigates what it means for pupils to learn to interpret archaeological artefacts. Research was conducted as a Learning study with 10 and 11-year-old pupils and lessons were performed as historical enquiry with archaeological artefacts. Three questions are posed: (1) how were the pupils’ historical consciousness activated by the archaeological artefacts, (2) how did the pupils experience the task of interpreting archaeological artefacts with an intercultural perspective, and (3) what are critical aspects for this learning? Three variation patterns that activated pupils’ historical consciousness are identified, including (a) material, (b) cultural and (c) normative contrasts. Four perception categories for historical interpretation of archaeological artefacts and three critical aspects are also identified. It is suggested that it is critical for the pupils to discern (i) historicity, (ii) historical representativeness and (iii) intercultural interaction in relation to artefacts and historical narratives. The study suggests that teachers could start from archaeological artefacts to activate pupils’ historical consciousness, rather than from textbook narratives and that pupils’ perceptions should be seen as a resource in enabling historical learning. Also, historical enquiry appears to be a reasonable approach to teaching intercultural perspectives on a historical content. These findings can be valuable for history educators and researchers who engage in teaching historical enquiry with an intercultural perspective from material culture.

    Molecular Design of HER3-Targeting Affibody Molecules: Influence of Chelator and Presence of HEHEHE-Tag on Biodistribution of 68Ga-Labeled Tracers2019In: International Journal of Molecular Sciences, ISSN 1422-0067, E-ISSN 1422-0067, Vol. 20, no 5, article id 1080Article in journal (Refereed)
    Abstract [en]

    Affibody-based imaging of HER3 is a promising approach for patient stratification. We investigated the influence of a hydrophilic HEHEHE-tag ((HE)3-tag) and two different gallium-68/chelator-complexes on the biodistribution of Z08698 with the aim to improve the tracer for PET imaging. Affibody molecules (HE)3-Z08698-X and Z08698-X (X = NOTA, NODAGA) were produced and labeled with gallium-68. Binding specificity and cellular processing were studied in HER3-expressing human cancer cell lines BxPC-3 and DU145. Biodistribution was studied 3 h p.i. in Balb/c nu/nu mice bearing BxPC-3 xenografts. Mice were imaged 3 h p.i. using microPET/CT. Conjugates were stably labeled with gallium-68 and bound specifically to HER3 in vitro and in vivo. Association to cells was rapid but internalization was slow. Uptake in tissues, including tumors, was lower for (HE)3-Z08698-X than for non-tagged variants. The neutral [68Ga]Ga-NODAGA complex reduced the hepatic uptake of Z08698 compared to positively charged [68Ga]Ga-NOTA-conjugated variants. The influence of the chelator was more pronounced in variants without (HE)3-tag. In conclusion, hydrophilic (HE)3-tag and neutral charge of the [68Ga]Ga-NODAGA complex promoted blood clearance and lowered hepatic uptake of Z08698. [68Ga]Ga-(HE)3-Z08698-NODAGA was considered most promising, providing the lowest blood and hepatic uptake and the best imaging contrast among the tested variants.

    Manligt och kvinnligt i skolämnet historia. Vad har det för konsekvenser för elevernas historiekultur?2019In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2019:1, p. 56-77Article in journal (Refereed)
    Abstract [sv]

    Utifrån intervjuer med elever i årskurs fem skildras i denna artikel elevernas historiekultur. Texten har två infallsvinklar, den första är elevernas uppfattning om manliga respektive kvinnliga aspekter av det förflutna. Den visade att eleverna främst ser manliga aktörer och manliga aktiviteter som riktig historia. Den andra infallsvinkeln är skillnader mellan pojkar och flickors inställningar till skolämnet historia och till historien som fenomen samt elevernas historiekultur. Den genomgången visade att flickor uppvisar ett större intresse än pojkarna för historia, både som skolämne och för att ta del av historia på fritiden. I artikeln påvisas att elevernas historiekultur förefaller vara inriktad på vad de beskriver som de stora händelserna i det förflutna. Pojkarna visar inget intresse för andra delar av det förflutna medan flickor också visar intresse för den vardagliga historien. Flickor framför att de behöver läsa historia för att få bra betyg medan både pojkar och flickor vill läsa historia för att bli allmänbildade och bli en del av samhället. Slutligen förs en diskussion av dessa aspekters relevans för skolämnet historia och dess under­visning.

    Abstract [en]

    History teachers – and researchers of history didactics – confront a still more pressing challenge: How are they supposed to cope with the fact that for the most important part, laypeople’s uses of history, and production of historical consciousness, are to be found outside school and other disciplinary uses of history? While the latter often struggle for attention and relevance among our students, uses of history within the popular and history culture of everyday life thrive more than ever -  in TV-series, films, reenactments, family genealogy, and so forth. Should history teachers, and researchers of history didactics to a predominantly degree ignore this fact? Should it be regarded it as an appendix to more traditional disciplinary uses of history, and official national narratives? Alternatively, could or should it rather be considered as constituting the pivotal point for future history teaching in schools, and research of history didactics? In order to discuss these and related questions, I believe we still require more empirically embedded examples, which highlight what seems to incite the uses of history among laypeople? What characterizes laypeople’s uses of history within the popular culture of everyday life? Consecutively, which criteria of relevance are at stake? In this article, I look for answers as laypeople use and interpret so-called n-words, like ‘neger’ and ‘nigger’ within Danish popular culture of the 2000s. Here we gain some insight into the personal and intimate uses of history among laypeople, embedded in emotional and contested issues concerning racism in African-Danes’ life stories on Facebook, postcolonial therapy of a ‘brown’ Danish satirist, and the longing for a ‘neger’ identity in Danish hip-hop.

    ABM-Based Supply Chain Risk Analysis and Modelling2016Conference paper (Refereed)
    Abstract [en]

    Understanding the impact of risks and related countermeasures in a supply chain is a challenging task. Especially, security risks, i.e. intentional and unauthorized acts against a supply chain, are considered emerging and important risks calling for heightened attention from managers as well as governmental actors. This paper aims to apply Agent Based Modelling to facilitate the quantification of the impacts of security risks and related countermeasures. Hence, the methodology is explained and a numerical case, based on postal operations in the region of Aragon, Spain, is provided. Results show that the methodology may provide very interesting insights in terms of reduction of security threats, potential to jam postal systems and ultimately experienced delays by customers.

    Watching, assessing, participating.: Globalising political education in Norwegian upper secondary education2019In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2019:1, p. 17-35Article in journal (Refereed)
    Abstract [en]

    Transnational governance is expanding rapidly. From a political education perspective, an important question is to what extent and how these are included in the political universe that adolescents are being prepared for at school. Of particular interest is social science, which is part of social studies in primary and lower secondary school, before it develops into a variety of social science courses in upper secondary school. Including the transnational level in political education may mean critical thinking about current transnational issues as well as understanding how to participate politically with a transnational aim. Are these elements included in Norwegian political education in social science at school? And if so, is such participation related to notions of influence, power and conflicting interests? Or are notions of participation based on classical idealism? The research method is an analysis of selected social science textbooks in Norwegian upper secondary education. Textbooks are not assumed to determine teaching, but they are assumed to frame the field within which teachers develop their practice. The analysis shows that in the textbooks political education is expanded to a transnational level, where both political judgement of issues as well as participation are elaborated upon.

    Vetenskaplig litteratur om internationell migration – en introduktion och diskussion2019In: Nordidactica: Journal of Humanities and Social Science Education, ISSN 2000-9879, no 2019:1, p. 1-16Article in journal (Refereed)
    Abstract [en]

    : International migration is one of the defining issues of our time. In this introduction to scientific texts on migration it is argued that teaching on migration in teacher training and in secondary and upper secondary school would benefit from the conscious use of the concept of powerful knowledge when texts are selected. Thus, about 30 peer-reviewed texts in English, Swedish and Norwegian on international migration are referred to and discussed from the point of view of powerful knowledge. Five concepts or perspectives are suggested as important and useful. These are push-pull as explanation to migration; levels of analysis; network; the role of women in migration and the role of religion in migration. Further, the tension between the positions of an alleged ‘methodological nationalism’ and the national characteristics of migration are discussed. Among the suggested concepts ‘levels of analysis’ and ‘network’ are proposed as especially important in order to develop powerful knowledge. Both concepts are highly useful in order to give teachers and students some structure and order in the studied issue while the concepts also can be re-contextualized to and used within other issue areas.

    Ny provningsmetodik för bestämning av bindemedlets korrosionsskyddande förmåga i betong2018Report (Other academic)
    Abstract [sv]

    Denna rapport omfattar slutrapporteringen av forskningsprojektet - Ny provningsmetodik för bedömning av bindemedlets korrosionsskyddande förmåga i betong – Underlag till LCA och livslängdsbedömning. I rapporten redovisas resultat från elektrokemiska undersökningar utförda på laboratorium och korrosionsprovningar i fält. Undersökningarna har genomförts av Swerea KIMAB, RISE CBI Betonginstitutet (väst och öst) samt Chalmers. Projektets mål har varit att genom en nationell samling av expertis ta fram en ny provningsmetodik som på ett enkelt och tillämpbart sätt ska utvärdera olika bindemedels korrosionsskyddande förmåga i betong. I denna undersökning har framför allt tiden till initiering av korrosion (gropfrätning) från det att kloriderna har nått stålytan och tills gropfrätning har initieras på stålytan undersökts. Tre olika accelererade elektrokemiska mätmetoder har använts och jämförts:

     Potentiostatisk mätmetod

     Potentiodynamisk mätmetod

     Galvanostatisk mätmetod

    Den framtagna provningsmetodiken med framställning av provkroppar har visat sig fungera väl. För att minska spridningen är det emellertid viktigt att använda en homogen och rengjord stålyta utan glödskal. Glödskalet avlägsnas lämpligast genom slipning eftersom betning kan bygga upp ett passivskikt på stålytan. För att undvika att betongrester fastnar på stålytan ska släta provstänger användas.

    Sammanfattningsvis kan sägas att resultaten från laboratorie- och fältmätningarna samt analyser av bindemedlens korrosionskänslighet genom TG- och XRD-analyser visade att denna kombination av mätningar ger ett bra verktyg att bedöma den korrosionsskyddande förmågan hos olika bindemedel. En sammanställning av rangordningen för bindemedlens korrosionsskyddande förmåga redovisas i tabellen nedan.

    Den korrosionsskyddande förmågan hos de undersökta bindemedlen rangordnas från en sammanvägning av de olika provningsmetoderna:

     bra < 1,5 och

     1,5 ≥mindre bra ≤2,5 och

     dåligt > 2,5.

    Som rangordningen visar i tabellen så har bindemedel med slagg och portlandcement med hög C 3A en bra korrosionsskyddande förmåga. Detta beror till största delen på kapaciteten att bilda Friedels salt från monosulfat under härdningsprocessen. Bindemedel som har en låg korrosionsskyddande förmåga har ett lågt C3A-innehåll och en inblandning av flygaska och/eller silika. Det medför dessutom en utspädningseffekt på förmågan att bilda Friedels salt.

    Bariatric Surgery: Outcomes after Gastric Bypass and Duodenal Switch2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Obesity is associated with increased morbidity and mortality. A BMI >40 kg/mshortens life expectancy by about 10 years. The obesity related comorbidities diabetes, hypertension, dyslipidemia and sleep apnea contributes to the increased risk of cardiovascular events. There is also an increased risk of some forms of cancer (e.g. colon, breast, and prostate cancer) as well as mental illness (depression and low self-esteem). Bariatric surgery is indicated for those with a BMI >35 kg/m2. Unfortunately, there are an increasing number of patients seeking bariatric surgery who are super obese (BMI >50 kg/m2), a condition more difficult to treat because of insufficient weight loss with standard operations, like the Roux-en-Y Gastric Bypass (RYGB). Therefore some surgeons advocate the Duodenal Switch (DS) in super obese patients, because DS results in greater and more sustained weight loss. However, DS is a technically more challenging operation and is associated with an increased risk of malnutrition and surgical complications. There are also concerns about an excessive loss of fat-free mass during weight loss after RYGB and especially after DS.

    This thesis focuses on weight-loss, effect on comorbidities, quality of life and complications after DS and RYGB, respectively, with comparisons between the two procedures in patients with super obesity. 

    DS resulted in a superior weight loss compared to RYGB (paper I, II and III) and body composition after weight loss did not differ compared with non-operated controls with the same BMI after surgery, for neither DS nor RYGB (paper I). Both DS and RYGB resulted in an improved metabolic control (paper II and III), but the effect on diabetes and hypertension was greater and maintained in the long-term after DS (paper III). Both DS and RYGB resulted in an improved physical quality of life, with greater improvements after DS (paper III). However, complications and long-term adverse effects were more common after DS (paper II and IV).

    In conclusion, the superior weight loss and greater improvements in several obesity-related comorbidities after DS must be weighed against the increased risk of complications and long-term adverse effects compared to RYGB.

    Alloy degradation in a co-firing biomass CFB vortex finder application at 880 degrees C2019In: Corrosion Science, ISSN 0010-938X, E-ISSN 1879-0496, Vol. 150, p. 136-150Article in journal (Refereed)
    Abstract [en]

    Mechanisms of alloy degradation in a fireside N-S-O-C-H-Cl-Na-K atmosphere at 880 degrees C were elucidated using SEM-EDS, chemical equilibrium calculations, and XRD. Alloys 310S, 800H/HT, and 600 were studied after 0, 8000, and 16,000 h exposure in a boiler co-firing biomass waste. For 310S and 800H/HT it was shown that nitrogen formed internal Cr nitrides lowering the Cr activity and inhibiting internal alloy Cr permeation, and that NaCl and Na2SO4 reacted with Cr oxide to form chromate and to accelerate the S and the Cl pickup. Alloy 600 showed no nitride or major chromate formation.
