    Förskolans dokumentations- och bedömningspraktik: En diskursanalys av förskollärares gemensamma tal om dokumentation och bedömning2018Licentiatavhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    The aim of the study is to contribute with knowledge about preschool documentation and assessment practice. The focus lies on preschool teachers’ mutual talk about documentation and assessment and how discourses about documentation and assessment practices are sustained, challenged or recreated. 

    In the study, the applied theory and method are taken from Norman Fairclough’s critical discourse analysis. The starting point of the study is the way preschool teachers in their speech acts express what they consider to be common sense with regard to documentation and assessment. The data material was constructed by using two focus groups with a total of 10 participant preschool teachers. The teachers’ speech acts were analyzed by applying the analysis concepts of modality and legitimacy. 

    The result shows that preschool teachers talk about documentation as something regulated by using the curriculum as authority, as well as something benefiting the reputation of preschool and its profession, children’s development as well as the development of preschool. In addition, documentation is mentioned as a tool for working with children’s interest and influence. These are the speech acts that legitimize documentation in preschool. In contrast, there are few speech acts that question preschool documentation practice. To legitimize challenging the current documentation practice, the question whether preschool is like a Big Brother world is asked. Photographs and film emerge as highly important documentation tools for benefiting children’s development, making the organization visible to caregivers, and for pinpointing learning. Children’s participation is legitimized by preschool teachers from various aspects, while children appear to have few possibilities to abstain from documentation. The participant teachers demonstrate both the necessity and the desirability of the assessment concept in preschool documentation and assessment practice. Their talk is of high modality both when referring to the undesirability of assessing the individual child and when admitting that this is something they are obliged to do. This is legitimized by their claim that the assessment is of benefit to the children. Assessing the relation between activities and children’s actions emerges as desirable in preschool teachers’ talk. 

    In the analysis of how preschool teachers talk about documentation and assessment, five different ways of referring to these processes can be distinguished. They comprise a power structure discourse as well as a learning, a professionalization, a digital and a welfare discourse. One conclusion to be drawn is that preschool teachers contribute to maintaining documentation as a natural part of preschool activities. Challenging preschool documentation and assessment practice occurs to some extent in that ethics discussions, which have not previously been included in preschool documentation and assessment practice, now enable teachers to discuss what their documentation requirement entails for the children.

    Solution, Solid-State, and Computational Analysis of Agostic Interactions in a Coherent Set of Low-Coordinate Rhodium(III) and Iridium(III) Complexes2018Inngår i: Chemistry - A European Journal, ISSN 0947-6539, E-ISSN 1521-3765, Vol. 24, nr 19, s. 4927-4938Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A homologous family of low‐coordinate complexes of the formulation trans‐[M(2,2′‐biphenyl)(PR3)2][BArF4] (M=Rh, Ir; R=Ph, Cy, iPr, iBu) has been prepared and extensively structurally characterised. Enabled through a comprehensive set of solution phase (VT 1H and 31P NMR spectroscopy) and solid‐state (single crystal X‐ray diffraction) data, and analysis in silico (DFT‐based NBO and QTAIM analysis), the structural features of the constituent agostic interactions have been systematically interrogated. The combined data substantiates the adoption of stronger agostic interactions for the IrIII compared to RhIII complexes and, with respect to the phosphine ligands, in the order PiBu3>PCy3>PiPr3>PPh3. In addition to these structure–property relationships, the effect of crystal packing on the agostic interactions was investigated in the tricyclohexylphosphine complexes. Compression of the associated cations, through inclusion of a more bulky solvent molecule (1,2‐difluorobenzene vs. CH2Cl2) in the lattice or collection of data at very low temperature (25 vs. 150 K), lead to small but statistically significant shortening of the M−H−C distances.

    Regenerative effects of human embryonic stem cell-derived neural crest cells for treatment of peripheral nerve injury2018Inngår i: Journal of Tissue Engineering and Regenerative Medicine, ISSN 1932-6254, E-ISSN 1932-7005, Vol. 12, nr 4, s. E2099-E2109Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Surgical intervention is the current gold standard treatment following peripheral nerve injury. However, this approach has limitations, and full recovery of both motor and sensory modalities often remains incomplete. The development of artificial nerve grafts that either complement or replace current surgical procedures is therefore of paramount importance. An essential component of artificial grafts is biodegradable conduits and transplanted cells that provide trophic support during the regenerative process. Neural crest cells are promising support cell candidates because they are the parent population to many peripheral nervous system lineages. In this study, neural crest cells were differentiated from human embryonic stem cells. The differentiated cells exhibited typical stellate morphology and protein expression signatures that were comparable with native neural crest. Conditioned media harvested from the differentiated cells contained a range of biologically active trophic factors and was able to stimulate in vitro neurite outgrowth. Differentiated neural crest cells were seeded into a biodegradable nerve conduit, and their regeneration potential was assessed in a rat sciatic nerve injury model. A robust regeneration front was observed across the entire width of the conduit seeded with the differentiated neural crest cells. Moreover, the up-regulation of several regeneration-related genes was observed within the dorsal root ganglion and spinal cord segments harvested from transplanted animals. Our results demonstrate that the differentiated neural crest cells are biologically active and provide trophic support to stimulate peripheral nerve regeneration. Differentiated neural crest cells are therefore promising supporting cell candidates to aid in peripheral nerve repair.

    DNA methylation holds prognostic information in relapsed precursor B-cell acute lymphoblastic leukemia2018Inngår i: Clinical Epigenetics, E-ISSN 1868-7083, Vol. 10, artikkel-id 31Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Few biological markers are associated with survival after relapse of B-cell precursor acute lymphoblastic leukemia (BCP-ALL). In pediatric T-cell ALL, we have identified promoter-associated methylation alterations that correlate with prognosis. Here, the prognostic relevance of CpG island methylation phenotype (CIMP) classification was investigated in pediatric BCP-ALL patients.

    Methods: Six hundred and one BCP-ALL samples from Nordic pediatric patients (age 1-18) were CIMP classified at initial diagnosis and analyzed in relation to clinical data.

    Results: Among the 137 patients that later relapsed, patients with a CIMP-profile (n = 42) at initial diagnosis had an inferior overall survival (pOS(5years) 33%) compared to CIMP+ patients (n = 95, pOS(5years) 65%) (p = 0.001), which remained significant in a Cox proportional hazards model including previously defined risk factors.

    Conclusion: CIMP classification is a strong candidate for improved risk stratification of relapsed BCP-ALL.

    Defect characterization of electron beam melted Ti-6Al-4V and Alloy 718 with X-ray microtomography2018Inngår i: Aeronautics and Aerospace Open Access Journal, ISSN 2576-4500, Vol. 2, nr 3, s. 139-145Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Electron beam melting (EBM) is emerging as a promising manufacturing process where metallic components are manufactured from three-dimensional (3D) computer aided design models by melting layers onto layers. There are several advantages with this manufacturing process such as near net shaping, reduced lead times and the possibility to decrease weight by topology optimization, aspects that are of interest for the aerospace industry. In this work two alloys, Ti-6Al-4V and Alloy 718, widely used within the aerospace industry were investigated with X-ray microtomography (XMT), to characterize defects such as lack of fusion (LOF) and inclusions. It was furthermore possible to view the macrostructure with XMT, which was compared to macrostructure images obtained by light optical microscopy (LOM). XMT proved to be a useful tool for defect characterization and both LOF and un-melted powder could be found in the two investigated samples. In the EBM built Ti-6Al-4V sample high density inclusions, believed to be composed of tungsten, were found. One of the high-density inclusions was found to be hollow, which indicate that the inclusion stems from the powder manufacturing process and not related with the EBM process. By performing defect analyses with the XMT software it was also possible to quantify the amount of LOF and un-melted powder in vol%. From the XMT-data meshes were produced so that finite element method (FEM) simulations could be performed. From these FEM simulations the significant impact of defects on the material properties was evident, as the defects led to high stress concentrations. It could moreover, with FEM, be shown that the as-built surface roughness of EBM material is of importance as high surface roughness led to increased stress concentrations.

    Implementation of clinical practice guidelines on lifestyle interventions in Swedish primary healthcare: a two-year follow up2018Inngår i: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 18, artikkel-id 227Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Implementation of interventions concerning prevention and health promotion in health care has faced particular challenges resulting in a low frequency and quality of these services. In November 2011, the Swedish National Board of Health and Welfare released national clinical practice guidelines to counteract patients' unhealthy lifestyle habits. Drawing on the results of a previous study as a point of departure, the aim of this two-year follow up was to assess the progress of work with lifestyle interventions in primary healthcare as well as the uptake and usage of the new guidelines on lifestyle interventions in clinical practice. Methods: Longitudinal study among health professionals with survey at baseline and 2 years later. Development over time and differences between professional groups were calculated with Pearson chi-square test. Results: Eighteen percent of the physicians reported to use the clinical practice guidelines, compared to 58% of the nurses. Nurses were also more likely to consider them as a support in their work than physicians did. Over time, health professionals usage of methods to change patients' tobacco habits and hazardous use of alcohol had increased, and the nurses worked to a higher extent than before with all four lifestyles. Knowledge on methods for lifestyle change was generally high; however, there was room for improvement concerning methods on alcohol, unhealthy eating and counselling. Forty-one percent reported to possess thorough knowledge of counselling skills. Conclusions: Even if the uptake and usage of the CPGs on lifestyle interventions so far is low, the participants reported more frequent counselling on patients' lifestyle changes concerning use of tobacco and hazardous use of alcohol. However, these findings should be evaluated acknowledging the possibility of selection bias in favour of health promotion and lifestyle guidance, and the loss of one study site in the follow up. Furthermore, this study indicates important differences in physicians and nurses' attitudes to and use of the guidelines, where the nurses reported working to a higher extent with all four lifestyles compared to the first study. These findings suggest further investigations on the implementation process in clinical practice, and the physicians' uptake and use of the CPGs.

    Contrasting plankton stoichiometry and nutrient regeneration in northern arctic and boreal lakes2018Inngår i: Aquatic Sciences, ISSN 1015-1621, E-ISSN 1420-9055, Vol. 80, nr 2, artikkel-id UNSP 24Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Contrasting carbon: nitrogen: phosphorus (C: N: P) stoichiometry between phytoplankton and zooplankton affect consumer growth and phytoplankton nutrient limitation via nutrient recycling by zooplankton. However, no study has assessed how regional differences in terrestrial loadings of organic matter affect plankton N: P stoichiometry and recycling in systems with low N deposition and N-limited phytoplankton. We address this question by using data from 14 unproductive headwater arctic and boreal lakes. We found that boreal lakes had higher lake water-and seston C, N and P concentrations than arctic lakes, whereas seston C: N, C: P and N: P ratios did not differ among regions. Boreal zooplankton were also richer in N and P relative to C, with lower somatic N: P ratios, compared to arctic lakes. Consequently, the estimated N: P imbalances between seston and zooplankton were negative in arctic lakes, indicating zooplankton feeding on phytoplankton of suboptimal N content, resulting in low consumer driven N: P recycling (medians arctic sub-mid and high altitude lakes: 11 and 13). In boreal lakes, estimated N: P imbalance did not differ from zero, with a seston N: P stoichiometry matching the N: P requirements of zooplankton, which resulted in higher consumer driven N: P recycling (median 18). Our results imply that regional climate induced catchment differences, through enhanced terrestrial nutrient inputs, affect plankton stoichiometry by raising consumer N: P recycling ratio and changing zooplankton from being mainly N-(arctic) to NP co-limited (boreal). Browning of lakes, in regions with low N deposition, may therefore promote large-scale regional changes in plankton nutrient limitation with potential feedbacks on pelagic food webs.

    Wave Phenomena and Beam-Plasma Interactions at the Magnetopause Reconnection Region2018Inngår i: Journal of Geophysical Research - Space Physics, ISSN 2169-9380, E-ISSN 2169-9402, Vol. 123, nr 2, s. 1118-1133Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper reports on Magnetospheric Multiscale observations of whistler mode chorus and higher-frequency electrostatic waves near and within a reconnection diffusion region on 23 November 2016. The diffusion region is bounded by crescent-shaped electron distributions and associated dissipation just upstream of the X-line and by magnetic field-aligned currents and electric fields leading to dissipation near the electron stagnation point. Measurements were made southward of the X-line as determined by southward directed ion and electron jets. We show that electrostatic wave generation is due to magnetosheath electron beams formed by the electron jets as they interact with a cold background plasma and more energetic population of magnetospheric electrons. On the magnetosphere side of the X-line the electron beams are accompanied by a strong perpendicular electron temperature anisotropy, which is shown to be the source of an observed rising-tone whistler mode chorus event. We show that the apex of the chorus event and the onset of electrostatic waves coincide with the opening of magnetic field lines at the electron stagnation point.

    Multiscale Currents Observed by MMS in the Flow Braking Region2018Inngår i: Journal of Geophysical Research - Space Physics, ISSN 2169-9380, E-ISSN 2169-9402, Vol. 123, nr 2, s. 1260-1278Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We present characteristics of current layers in the off-equatorial near-Earth plasma sheet boundary observed with high time-resolution measurements from the Magnetospheric Multiscale mission during an intense substorm associated with multiple dipolarizations. The four Magnetospheric Multiscale spacecraft, separated by distances of about 50 km, were located in the southern hemisphere in the dusk portion of a substorm current wedge. They observed fast flow disturbances (up to about 500 km/s), most intense in the dawn-dusk direction. Field-aligned currents were observed initially within the expanding plasma sheet, where the flow and field disturbances showed the distinct pattern expected in the braking region of localized flows. Subsequently, intense thin field-aligned current layers were detected at the inner boundary of equatorward moving flux tubes together with Earthward streaming hot ions. Intense Hall current layers were found adjacent to the field-aligned currents. In particular, we found a Hall current structure in the vicinity of the Earthward streaming ion jet that consisted of mixed ion components, that is, hot unmagnetized ions, cold ExB drifting ions, and magnetized electrons. Our observations show that both the near-Earth plasma jet diversion and the thin Hall current layers formed around the reconnection jet boundary are the sites where diversion of the perpendicular currents take place that contribute to the observed field-aligned current pattern as predicted by simulations of reconnection jets. Hence, multiscale structure of flow braking is preserved in the field-aligned currents in the off-equatorial plasma sheet and is also translated to ionosphere to become a part of the substorm field-aligned current system.

    On avoiding and completing edge colorings2018Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    These papers are all related to the problem of avoiding and completing an edge precoloring of a graph. In more detail, given a graph G and a partial proper edge precoloring φ of G and a list assignment L for every non-colored edge of G, can we extend the precoloring to a proper edge coloring avoiding any list assignment? In the first paper, G is a d-dimensional hypercube graph Qd, a partial proper edge precoloring φ and every list assignment L must satisfy certain sparsity conditions. The second paper still deals with d-dimensional hypercube graph Qd, but the list assignment L for every edge of Qd is an empty set and φ must be a partial proper edge precoloring of at most (d - 1) edges. For the third paper, G can be seen as a complete 3-uniform 3-partite hypergraph, every list assignment L must satisfy certain sparsity conditions but we do not have a partial proper edge precoloring φ on edges of G.

    Nordic urban nature recreation: How to practically integrate economic values in decision-making2018Bok (Annet vitenskapelig)
    Abstract [en]

    The Nordic countries continue to experience growth of urban areas, which provides benefits like economic growth, but also imposes economic costs in terms of reduced ecosystem services. This report focuses on urban nature recreation and highlights economic methods and data that can help capture the associated nonmarket welfare benefits. The study stresses the need to collect user data to better understand visitation patterns, which can be combined with valuation methods to provide evidence of economic benefits associated with e.g., hiking, cycling, skiing, paddling and other recreation activities. Once these benefits are visible, decision-makers will have a better basis to balance economic growth with the environmental costs it imposes on urban ecosystem services.

    Early Childhood Obesity Risk Factors: Socioeconomic Adversity, Family Dysfunction, Offspring Distress, and Junk Food Self-Medication.2018Inngår i: Current Obesity Reports, E-ISSN 2162-4968, Vol. 7, nr 2, s. 204-209Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE OF REVIEW: To explore the sequence and interaction of infancy and early childhood risk factors, particularly relating to disturbances in the social environment, and how the consequences of such exposures can promote weight gain and obesity.

    RECENT FINDINGS: This review will argue that socioeconomic adversity is a key upstream catalyst that sets the stage for critical midstream risk factors such as family strain and dysfunction, offspring insecurity, stress, emotional turmoil, low self-esteem, and poor mental health. These midstream risk factors, particularly stress and emotional turmoil, create a more or less perfect foil for calorie-dense junk food self-medication and subtle addiction, to alleviate uncomfortable psychological and emotional states. Disturbances in the social environment during infancy and early childhood appear to play a critical role in weight gain and obesity, through such mechanisms as insecurity, stress, and emotional turmoil, eventually leading to junk food self-medication and subtle addiction.

    Tax Governance: Corporate experiences with Cooperative Compliance in Denmark2018Rapport (Fagfellevurdert)
    Abstract [en]

    This working paper presents an analysis of the experiences of Cooperative Compliance in Denmark. Cooperative Compliance denotes a specific kind of collaborative program for the regulation of large corporate taxpayers by the tax authorities. Cooperative Compliance programs have been implemented in several countries worldwide. In Denmark the program is called Tax Governance. Tax Governance has been studied using qualitative method and the analyses of the working paper build on an extensive base of in-depth interviews – primarily with tax directors from corporations participating in the program. The working paper shows as a general stance that the corporations are supporting the ideas behind Tax Governance and are generally satisfied with their participation. However, the working paper also shows that most of them explain to be stretched between this willingness to participate and the different challenges and contradictions they told to experience in the everyday work practices related to the Tax Governance program. The working paper zooms in at these various everyday experiences from the corporations. Yet, it also zooms out and shows that the Tax Governance program in different ways relate to wider international trends within tax administration, especially concerning the development of risk assessments and internal control in the corporations and a greater focus on monitoring of these elements by the tax authorities. Overall, the working paper concludes that Tax Governance as a model for a collaborative regulatory relationship between Skat and large corporations comes with both possibilities and challenges.

    Common Perceived Barriers and Facilitators for Reducing Sedentary Behaviour among Office Workers.2018Inngår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 15, nr 4, artikkel-id E792Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Qualitative studies identified barriers and facilitators associated with work-related sedentary behaviour. The objective of this study was to determine common perceived barriers and facilitators among office workers, assess subgroup differences, and describe sedentary behaviour. From two Swedish companies, 547 office workers (41 years (IQR = 35–48), 65% women, 66% highly educated) completed questionnaires on perceived barriers and facilitators, for which subgroup differences in age, gender, education, and workplace sedentary behaviour were assessed. Sedentary behaviour was measured using inclinometers (n = 311). The most frequently reported barrier was sitting is a habit (67%), which was reported more among women than men (X2 = 5.14, p = 0.03) and more among highly sedentary office workers (X2 = 9.26, p < 0.01). The two other most reported barriers were that standing is uncomfortable (29%) and standing is tiring (24%). Facilitators with the most support were the introduction of either standing- or walking-meetings (respectively 33% and 29%) and more possibilities or reminders for breaks (31%). The proportion spent sedentary was 64% at the workplace, 61% on working days, and 57% on non-working days. This study provides a detailed understanding of office workers’ ideas about sitting and means to reduce sitting. We advise to include the supported facilitators and individualized support in interventions to work towards more effective strategies to reduce sedentary behaviour.

    Quality and learning aspects of the first 9000 spirometries of the LifeGene study2018Inngår i: NPD Bulletin, ISSN 1892-8110, E-ISSN 2055-1010, Vol. 28, artikkel-id 6Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Spirometry requires the patient to cooperate and do the manoeuvre 'right' for reliable results. Algorithms to assess test quality as well as educational recommendations for personnel are defined in guidelines. We compared the quality of forced spirometry tests performed by spirometry technicians with little or no previous experience of spirometry using spirometry systems with different modes of feedback. In both cases, the spirometry technician received general feedback on the screen based on ATS/ERS guidelines, such as 'exhale faster' and 'exhale longer'. The major difference was whether quality grading system of the complete session was available simultaneously on screen, or in the printed report afterwards. Two parts of the same population-based study (LifeGene), the pilot (LG1) and the first part (LG2) of the subsequent study, were compared retrospectively. In LG1 (on-screen grading) approved examination quality was achieved for 88% of the 10 first subjects for each spirometry technician compared to 70% in LG2 (printed grading afterwards). The corresponding values after 40 subjects was 94 % in LG1, compared to 73% in LG2, and after the first ten subjects there was no apparent quality improvement in either LG1 or LG2. The quality for LG1 is among the highest reported in the literature even though the spirometry technician were relatively inexperienced. We conclude that on-screen grading in addition to general technical quality feedback is powerful in enhancing the spirometry test session quality.

    Optimizing the yield and physico-chemical properties of pine cone cellulose nanocrystals by different hydrolysis time2018Inngår i: Cellulose (London), ISSN 0969-0239, E-ISSN 1572-882X, Vol. 25, nr 5, s. 2925-2938Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cellulose nanocrystals (CNCs) were isolated for the first time from pine cones (PC) by alkali and bleaching treatments and subsequent sulfuric acid hydrolysis (64%) at 45 degrees C. The influence of the hydrolytic reaction time (30, 45, and 90 min) on the yield, chemical composition and structure, and thermal stability of CNCs was evaluated. The removal of non-cellulosic constituents during the alkaline and bleaching treatment resulted in high pure cellulosic fibres. The isolation of CNCs from these cellulosic fibres at different reaction times was verified by the nano-dimensions of the individual crystals (< 3 and < 335 nm of average diameter and length, respectively). The highest yield (15%) and the optimum CNCs properties in terms of aspect ratio, thermal stability and crystallinity were obtained for an extraction time of 45 min. PC appeared to be a new promising source of cellulose fibres and CNCs with potential to be applied as reinforcement in composites and for food-packaging.

    Measurement of quarkonium production in proton-lead and proton-proton collisions at 5.02 TeV with the ATLAS detector2018Inngår i: European Physical Journal C, ISSN 1434-6044, E-ISSN 1434-6052, Vol. 78, nr 3, artikkel-id 171Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The modification of the production of J/psi, psi(2S), and gamma (nS) (n = 1, 2, 3) in p+Pb collisions with respect to their production in pp collisions has been studied. The p+Pb and pp datasets used in this paper correspond to integrated luminosities of 28 nb(-1) and 25 pb(-1) respectively, collected in 2013 and 2015 by the ATLAS detector at the LHC, both at a centre-of-mass energy per nucleon pair of 5.02 TeV. The quarkonium states are reconstructed in the dimuon decay channel. The yields of J/psi and psi(2S) are separated into prompt and non-prompt sources. The measured quarkonium differential cross sections are presented as a function of rapidity and transverse momentum, as is the nuclear modification factor, R-pPb for J/psi and psi (nS). No significant modification of the J/psi production is observed while gamma (nS) production is found to be suppressed at low transverse momentum in p+Pb collisions relative to pp collisions. The production of excited charmonium and bottomonium states is found to be suppressed relative to that of the ground states in central p+Pb collisions.

    Sandgrunnorna in Lule Archipelago: Recent Transformation of a Glaciofluvial Deposit in an Environment of Land Uplift1985Licentiatavhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    In an area of rapid land uplift the geomorphological evolution of the glaciofluvial island of Sandgrunnorna, 25 km SE Luleå, in the Bothnian Bay, is discussed from old maps, air photographs and field studies. The island were marked on a map for the first time in 1790, but the highest parts can be estimated to have reached the sea surface about 100 years earlier. The areal growth has been reconstructed by map and air photograph studies. A model of the geomorphological evolution based on the interaction between bottom morphology, land uplift and waves is presented.

    Design of Suspension Plasma Sprayed Thermal Barrier Coatings2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Thermal barrier coatings (TBCs) are widely used on gas turbine components to provide thermal insulation, which in combination with advanced cooling, can enable the gas turbine to operate at significantly higher temperatures even above the melting temperature of the metallic components. There is a permanent need,mainly due to environmental reasons, to increase the combustion temperature inturbines, hence new TBC solutions are needed. By using a liquid feedstock in thermal spraying, new types of TBCs can be produced. Suspension plasma/flame or solution precursor plasma spraying are examples of techniques that can be utilized for liquid feedstock thermal spraying. This approach of using suspension and solution feedstock, which is an alternative to the conventional solid powder feedstock spraying, is gaining increasing research interest since it has been shown to be capable of producing coatings withsuperior performance. The objective of this research work was to identify relationships between process parameters, coating microstructure, thermal conductivity and lifetime in suspension plasma sprayed TBCs. A further objective was to utilize these relationships to enable tailoring of the TBC microstructure for superior performance compared to state-of-the-art TBC used in industry today, i.e. solid feedstock plasma sprayed TBCs. Different spraying techniques, namely suspension high velocity oxy fuel, solution precursor plasma and suspension plasma spraying (with axial and radial feeding) were explored and compared to solid feedstock plasma spraying. A variety of microstructures, such as highly porous, vertically cracked and columnar, were produced and investigated. It was shown that there are strong relationships between microstructure, thermo-mechanical properties and performance of the coatings. Specifically, axial suspension plasma spraying wasshown as a very promising technique to produce various microstructures as wellas highly durable coatings. Based on the experimental results, a tailored columnar microstructure design for a superior TBC performance is also proposed.

    L'Expression de la mauvaise conscience dans l'oeuvre de Benjmain Constant2008Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [fr]

    L’étude d’un thème transversal comme celui de la mauvaise conscience dans l’œuvre de Constant nécessite une méthodologie particulière. Le manque d’homogénéité des écrits de cet auteur disqualifie les approches biographique et générique et exige une perspective holistique. S’interroger sur les conséquences morales de la mauvaise conscience permet à la fois de tenir compte de la diversité des écrits et d’aborder l’épineux problème de la sincérité immanquablement lié à toute étude de la mauvaise conscience en littérature. Ce travail s’est attaché à démontrer comment les catégories morales qui constituent cette affection psychologique se réalisent dans l’œuvre de Constant. Cette tâche a été menée en comparant les quatre grands types d’écrits constituant l’œuvre de ce dernier (les écrits portant sur la religion, ceux sur la politique, les écrits littéraires et les écrits intimes) tout d’abord sous l’angle du remords dont a été démontré qu’il sert d’enjeu dans les relations entre les hommes dans les écrits théoriques en plus d’être la manifestation la plus patente de la mauvaise conscience dans les écrits littéraires et intimes. Dans un deuxième temps, les fondements philosophiques de la douleur ont été dégagés avant de montrer qu’elle est simultanément cause et effet de la mauvaise conscience dans les écrits littéraires et intimes. Troisièmement, ont été distinguées les caractéristiques de la dissimulation puisqu’elle est à la base de la condamnation par Constant des agissements culpabilisants des instances qui ont dominé l’humanité et la source des comportements coupables des personnages et de l’auteur lui-même.

    Policy Brief - Ecodesign Requirements for Textiles and Furniture: Eco design requirements that can be drawn up for non-energy-related products are in focus2018Annet (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    Policy Brief: Ecodesign Requirements for Textiles and Furniture The EU Eco design Directive’s potential for application to nonenergy related themes has come under the spotlight in recent years with Nordic countries at the forefront. A large part of the lifecycle environmental impacts of a product are determined at the design stage.

    In this report potential eco design requirements that can be drawn up for non-energy-related products are in focus. Textiles are here used as an example, and a light application of the approach has subsequently been applied to the furniture sector. Clothing and home textiles were chosen due to significant wastage in the value chain due to fast fashion, dropping quality and relatively low repair and reuse rates.

    The project was initiated, financed and steered by the Nordic Council of Ministers’ Working Group for Sustainable Consumption and Production and carried out by a consultant team led by PlanMiljø.

    Silicon Nanopore Arrays: Fabrication and Applications for DNA Sensing2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Nanopore biomolecule sensing and sequencing has emerged as a simple but powerful tool for single molecule studies over the past two decades. By elec- trophoretically driving single molecules through a nanometer-sized pore, often sitting in an insulating membrane that separates two buffer solutions, ionic current blockades can be detected to reveal rich information of the molecules, such as DNA length, protein size and conformation, even nucleic acid se- quence. Biological protein pores, as well as solid-state nanopores have been used, but both suffer from relatively low throughput due to the lack of abil- ity to scale up to a large array. In this thesis, we tackled the throughput issue from the fabrication aspect as well as from the detection aspect, aim- ing at a parallel optical single molecule sensing on an array of well-separated nanopores.

    From the fabrication aspect, several lithography-based self-regulating meth- ods were tested to obtain nanopore arrays in silicon membranes, including anisotropic KOH etching, thermal oxidation-induced pore shrinkage, metal- assisted etching and electrochemical etching. Among those, the most success- ful method was the electrochemical etching of silicon. By electron-beam or photo lithography, the positions of the pores were defined on a silicon mem- brane. Followed by anisotropic KOH etching, inverted pyramids were formed as etching pits. The nanopores were then formed by anodic etching of silicon in HF. Using this concept, the size of the pores does not depend on the lithog- raphy step; only the positions of pores were defined by lithography. In this way, an array of ∼ 900 pores with an average entrance diameter of 18 ± 4 nm was fabricated on a 120 μm × 120 μm membrane.

    From the detection aspect, parallel readout of fluorescence signals from the labelled DNA molecules while translocating through an array of nanopores was performed using a wide-field microscope with a relatively fast CMOS camera recording at 1 KHz frame rate. Statistics of duration and frequency of the translocation events were extracted and studied. It was found that the event duration decreases with rising excitation laser power. This can be attributed to a laser-induced heating effect. Simulation suggested that a sig- nificant thermal gradient was generated at the pore vicinity by the excitation laser due to photon absorption by the silicon membrane. Such temperature rise affects all mass transport in a solution via a viscosity change. The ther- mal effect has also been proven by that conductance of an array of nanopores scales with the laser power. The thermal effect on the translocation frequency has been studied systematically as well. Due to thermophoresis of DNA in a thermal gradient, the thermophoretic force serves as a repulsion force, op- posing the electrophoretic force at the pore vicinity, depleting molecules away from the pore. Because of the molecule-size-dependent thermal depletion, a size-dependent translocation frequency was observed. This can be potentially used for a high throughput molecule sorting by adjusting the balance between the thermophoretic force and the electrophoretic force.

    Cholesterol enhances influenza binding avidity by controlling nanoscale receptor clustering2018Inngår i: Chemical Science, ISSN 2041-6520, E-ISSN 2041-6539, Vol. 9, nr 8, s. 2340-2347Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Influenza virus infects cells by binding to sialylated glycans on the cell surface. While the chemical structure of these glycans determines hemagglutinin-glycan binding affinity, bimolecular affinities are weak, so binding is avidity-dominated and driven by multivalent interactions. Here, we show that membrane spatial organization can control viral binding. Using single-virus fluorescence microscopy, we demonstrate that the sterol composition of the target membrane enhances viral binding avidity in a dose-dependent manner. Binding shows a cooperative dependence on concentration of receptors for influenza virus, as would be expected for a multivalent interaction. Surprisingly, the ability of sterols to promote viral binding is independent of their ability to support liquid-liquid phase separation in model systems. We develop a molecular explanation for this observation via molecular dynamics simulations, where we find that cholesterol promotes small-scale clusters of glycosphingolipid receptors. We propose a model whereby cholesterol orders the monomeric state of glycosphingolipid receptors, reducing the entropic penalty of receptor association and thus favoring multimeric complexes without phase separation. This model explains how cholesterol and other sterols control the spatial organization of membrane receptors for influenza and increase viral binding avidity. A natural consequence of this finding is that local cholesterol concentration in the plasma membrane of cells may alter the binding avidity of influenza virions. Furthermore, our results demonstrate a form of cholesterol-dependent membrane organization that does not involve lipid rafts, suggesting that cholesterol's effect on cell membrane heterogeneity is likely the interplay of several different factors.

    Quality and learning aspects of the first 9000 spirometries of the LifeGene study2018Inngår i: NPJ primary care respiratory medicine, ISSN 2055-1010, Vol. 28, artikkel-id 6Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Spirometry requires the patient to cooperate and do the manoeuvre 'right' for reliable results. Algorithms to assess test quality as well as educational recommendations for personnel are defined in guidelines. We compared the quality of forced spirometry tests performed by spirometry technicians with little or no previous experience of spirometry using spirometry systems with different modes of feedback. In both cases, the spirometry technician received general feedback on the screen based on ATS/ERS guidelines, such as 'exhale faster' and 'exhale longer'. The major difference was whether quality grading system of the complete session was available simultaneously on screen, or in the printed report afterwards. Two parts of the same population-based study (LifeGene), the pilot (LG1) and the first part (LG2) of the subsequent study, were compared retrospectively. In LG1 (on-screen grading) approved examination quality was achieved for 88% of the 10 first subjects for each spirometry technician compared to 70% in LG2 (printed grading afterwards). The corresponding values after 40 subjects was 94 % in LG1, compared to 73% in LG2, and after the first ten subjects there was no apparent quality improvement in either LG1 or LG2. The quality for LG1 is among the highest reported in the literature even though the spirometry technician were relatively inexperienced. We conclude that on-screen grading in addition to general technical quality feedback is powerful in enhancing the spirometry test session quality.

    Utveckling av mer platsberoende parameterisering av ICECREAMDB2009Rapport (Annet vitenskapelig)
    Abstract [sv]

    Tidigare jämförelser mellan uppmätta fosforförluster och simulerade resultat med ICECREAMDB-modellen visade vissa systematiska avvikelser som kunde kopplas till jordarten i de studerade områdena (Djodjik m.fl., 2008). I den tidigare studien var simuleringarna gjorda med de standardiserade parameteriseringarna för olika jordarter som användes för PLC5-beräkningarna. Inför nästa PLC-omgång bedömde vi det därför som viktigt att se över generaliteten i den jordartsrelaterade parameteriseringen och också göra en bedömning av hur platsberoende den är. I den här rapporten redovisas ett inledande arbete där den jordartsrelaterade PLC5-parameteriseringen respektive mer platsspecifik parameterisering testades på tre olika fält som ingår i miljöövervakningsprogrammet ”Observationsfält på åkermark”. Fälten består av jordarterna sandy loam och loam och valdes eftersom derepresenterar jordarter som förekommer i samtliga läckageregioner i Sverige och motsvarar över 50% av jordbruksarealen i 12 av de 22 regionerna. De spelar därför en viktig roll vid beräkningen av de regionala utlakningskoefficienterna.

    Resultaten visade att standardparameteriseringarna för ICECREAMDB-modellen från PLC5 beräkningarna fungerade i stort sett bra för att återge avrinningsmönstreti de tre observationsfälten vid simuleringar under 5-9 års perioder. Simuleringarna återgav i stort sett mätvärdena för när flödestopparna börjar och slutar, men inte på något fält lyckades modellen återge pikflödena i flödestopparna och den ackumulerade avrinningen underskattades i fyra av de fem olika körningarna. För de simulerade resultaten av P-förluster gällde det omvända, då förlusten av både total-P och löst P överskattades med standardparameteriseringarna.

    Med platsspecifik parameterisering underskattades avrinningen ytterligare, medan överskattningen av total-P minskade. Vid testen av den platsspecifika parameteriseringen hade sättningen av vattenlagringskapaciteten i marken, dvs porositet, fältkapacitet och vissningsgräns, stor betydelse för totala avrinningen och för fördelningen av flödena mellan ytavrinning, makroporflöde och flöde i mikroporregionen. Eftersom vattenflödena i sin tur styr P-flödena i modellen hade dessa parametrar även stor betydelse för P-flödena. Små förändringar i parameteriseringen av både lerhalten och pH hade stor påverkan på de simulerade fosforförlusterna. Inte i något fall förbättrades precisionen i beräkningarna då parametrar för vattenlagringskapaciteten i marken sattes efter fältdata istället för enligt de funktioner som använts i PLC5-arbetet.

     Det här presenterade arbetet var en inledande test av några av de standardparameteriseringar som användes i PLC5-beräkningarna. En fortsatt studie, finansierad inom ramen för SLUs fortlöpande miljöanalysarbete kommer att göras under 2009 för att täcka in fler jordarter och också större regionala skillnader vad gäller klimatfaktorerna.

    Tourism, nature and sustainability: A review of policy instruments in the Nordic countries2018Bok (Annet vitenskapelig)
    Abstract [en]

    Recently, the Nordic countries have experienced a rapid growth in numbers of visitors. At some popular nature attractions this has resulted in crowding, environmental damage, costly rescue operations and overload on public infrastructure. Implementation of economic policy instruments have hence been suggested to secure a more sustainable development. While the applicability of e.g. entrance fees is restricted by the public rights of access, economic instruments tend to represent short-sighted solutions. Sustainable development requires holistic policies, which take environmental, social and economic aspects into consideration in a long-term perspective. To achieve a more sustainable development of tourism, it is suggested that a limited use of economic instrument should take place in combination with adaptive management strategies and available legal and administrative instruments.

    Testplatser för 74 ton tunga fordon: två instrumenterade tunna vägkonstruktioner2018Rapport (Annet vitenskapelig)
    Abstract [sv]

    Denna rapport beskriver i korthet installeringen av vägteknisk instrumentering samt klimatsensorer på två testplatser i Norrbottens län. Båda testplatserna kan klassas som tunna vägöverbyggnader. Den ena strukturen ligger längs Lv373 strax öster om Långträsk och den andra på Lv515 strax söder om korsningen vid Lv373. Huvudsyftet med testplatserna är att få bättre information om hur de nya 74 ton tunga fordonen påverkar vägarna. Detta skall göras genom att mäta konstruktionernas respons vid passerande lastbilar och vid belastning med fallviktsapparat.

    Den vägtekniska instrumenteringen består av töjningsgivare i tvärgående samt längsgående riktning för bestämning av dragtöjning i beläggningens underkant samt vertikala töjningsgivare för att bestämma varje lagers trycktöjning. Dessutom är spänningsmätare inlagda i överbyggnaden för att mäta den vertikala spänningen på två nivåer. Datainsamling om det lokala klimatet görs med hjälp av tjäl- och fuktstav samt temperaturgivare i beläggningen. En SMHI väderstation ligger omkring 15 km nordnordöst om testplatserna och trafikverket har en VViS-station som ligger längs Lv373 öster om testplatserna. De första responsmätningarna är planerade under sommaren 2018.

    Inventering av sirlig skivsnäcka (Anisus vorticulus) i Skåne 20172017Rapport (Annet vitenskapelig)
    Abstract [sv]

    Rapporten redovisar resultatet från eftersök av sirlig skivsnäcka (Anisus vorticulus) på 49 potentiella lokaler i Skåne 2017. Inventeringen har gjorts på uppdrag av Länsstyrelsen Östergötland inom ramen för biogeografisk uppföljning. Syftet har varit att återfinna arten på någon av sina få tidigare kända lokaler och om möjligt finna den på nya. Sirlig skivsnäcka är mycket sällsynt i Sverige och har aldrig hittats utanför Skåne. Arten är fridlyst och klassas som sårbar (VU) på den nationella rödlistan och är upptagen i Habitatdirektivets bilaga 2 och 4. Inga fynd av arten gjordes vid inventeringen men blåssnäcka och flera andra naturvårdsintressanta arter påträffades. Ytterligare lämpliga lokaler för sirlig skivsnäcka kan finnas att undersöka i "storklandskapet" längs med Klingavälsån mellan Sövdesjön och Kävlingeån.

    Översyn av läckagekoefficienter för N-läckage från lerjordar2012Rapport (Annet vitenskapelig)
    Abstract [sv]

    I samband med retentionsberäkningar i vissa avrinningsområden med åker på ler-jordar har problem uppstått med låga bruttobelastningar. Detta skulle kunna bero på för låga kvävehalter för lerjordar som använts som indata. En översyn har därför utförts av de beräknade kväveläckagekoefficienterna för jordbruksmark för styv lera (clay) från TRK och PLC5.

    För att kunna jämföra utveckling och förändringar av metoden för beräkningar av läckagekoefficienterna (NLeCCS) mellan TRK och PLC5 har beräkningar för år 1999 utförda inom ramen för TRK projektet jämförts med senare utförda beräk-ningar för 1999 med PLC5-metoden. För att utvärdera hur förändringarna mellan de två metoderna påverkat utlakningen från lerjordarna har beräkningen för 1999 med PLC5-metoden använts som utgångspunkt och manipulerats för att utvärdera enskilda förändringar mellan de två metoderna. Effekten av förändringar av rotdjup för clay, ändrad klimatperiod (och målavrinning), ogräsupptag, vallinsådd, vårbe-arbetning, rotdjup för träda och halt organiskt material i marken beräknades. För-ändringen av rotdjup för vissa grödor påverkade bara beräkningen för clay medan de övriga förändringarna som testats även påverkade beräkningen för de övriga jordarna. Förändringen av rotdjupet av vissa grödor ökade koncentrationen för clay i alla regioner och ändrad klimatperiod gav både ökade och minskade koncentrat-ioner i regionerna. I region 4 och 6 gav ändrat rotdjup för clay och ändrad klimat-period ungefär samma koncentration med PLC5-metoden som med TRK-metoden.

    En genomgång av uppmätta kvävehalter från rutförsök, observationsfält och ty-pområden på jordbruksmark som domineras av styv lera har gjorts. I dessa områ-den varierade långtidsmedelvärdena mellan 3,3 och 5,3 mg NO3-N/l. I motsva-rande regioner (4, 5a och 6) var de beräknade koncentrationerna i TRK i samma storleksordning, medan koncentrationerna beräknade med PLC5-metodiken var något lägre.

    Med FyrisNP simulerades N-transport från ett avrinningsområde dominerat av styv lera med användning av läckagekoefficienter (PLC5-metodik), lokal grödfördel-ning och förbättrad jordartskarta. Simuleringarna kunde inte uppnå uppmätta N-koncentrationer i utloppspunkten för område U8 (Figur 27), varken med koeffici-enterna från TRK eller PLC5 med regional eller lokal grödfördelning. Den bästa överenskommelsen med uppmätta värden nåddes då läckagekoefficienterna från PLC5 räknades upp 2,5 gång.

    Thermodynamic and kinetic investigation of systems related to lightweight steels2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Lightweight steels have attracted considerable interest for automobile applications due to the weight reduction without loss of high strength and with retained excellent plasticity. In austenitic Fe-Mn-Al-C steels, the nano-precipitation of the κ-carbide within the austenitic matrix significantly contributes to the increase in yield strength. In the present work, the precipitation strengthening simulation has been carried out within the framework of the ICME approach. Thermodynamic assessments of the quaternary Fe-Mn-Al-C system as well as its sub-ternary systems were performed with the CALPHAD method. All available information on phase equilibria and thermochemical properties were critically evaluated and used to optimize the thermodynamic model parameters. By means of the partitioning model, the κ-carbide was described using a five-sublattice model (four substitutional and one interstitial sublattice), which can reflect the ordering between metallic elements and reproduce the wide homogeneity range of the κ-carbide. Based on the present thermodynamic description, a thermodynamic database for lightweight steels was created. Using the database, the phase equilibria evolution in lightweight steels can be satisfactorily predicted, as well as the partition of alloying elements. In order to accelerate the development of a kinetic database for multicomponent systems, a high-throughput optimization method was adopted to optimize the diffusion mobilities. This method may largely reduce the necessary diffusion-couple experiments in multicomponent systems. Based on the developed thermodynamic and kinetic databases for lightweight steels, the precipitation of the κ-carbide was simulated using TC-PRISMA. The volume fraction and particle size were reasonably reproduced. Finally, the precipitation strengthening contribution to the yield strength was predicted. The calculation results show that the anti-phase boundary effect is predominant in the precipitation strengthening. Overall, the relationship between the composition, processing parameters, microstructure and mechanical properties are established in the thesis.

    A Two Dimensional Model of the Thin Laminar Wall of a Curvilinear Flexible Pipe2018Rapport (Annet vitenskapelig)
    Abstract [en]

    We present a two dimensional model describing the elastic behaviour of the wall of a curved pipe to model blood vessels in particular. The wall has a laminate structure consisting of several anisotropic layers of varying thickness and is assumed to be much smaller in thickness than the radius of the vessel which itself is allowed to vary. Our two-dimensional model takes the interaction of the wall with the surrounding material and the fluid flowing inside into account and is obtained via a dimension reduction procedure. The curvature and twist of the vessel axis as well as the anisotropy of the laminate wallpresent the main challenges in applying the dimension reduction procedure so plenty of examples of canonical shapes of vessels and their walls are supplied with explicit systems of dierential equations at the end.

    The influence of rearing on behavior, brain monoamines and gene expression in three-spined sticklebacks2018Dataset
    Abstract [en]
    1. The causes of individual variation in behavior are often not well understood, and potential underlying mechanisms include both intrinsic and extrinsic factors, such as early environmental, physiological, and genetic differences.
    2. In an exploratory laboratory study, we raised three-spined sticklebacks (Gasterosteus aculeatus) under 4 different environmental conditions (simulated predator environment, complex environment, variable social environment, and control). We investigated how these manipulations related to behavior, brain physiology and gene expression later in life, with focus on brain dopamine and serotonin levels, turnover rates, and gene expression.
    3. The different rearing environments influenced behavior and gene expression, but did not alter monoamine levels or metabolites. Specifically, compared to control fish, fish exposed to a simulated predator environment tended to be less aggressive, more exploratory, and more neophobic; and fish raised in both complex and variable social environments tended to be less neophobic. Exposure to a simulated predator environment tended to lower expression of dopamine receptor DRD4A, a complex environment increased expression of dopamine receptor DRD1B, while a variable social environment tended to increase serotonin receptor 5-HTR2B and increased serotonin transporter SLC6A4A expression. Despite both behavior and gene expression varying with early environment, there was no evidence that gene expression mediated the relationship between early environment and behavior.
    4. Our results confirm that environmental conditions early in life can affect phenotypic variation. However, the mechanistic pathway of the monoaminergic systems translating early environmental variation into observed behavioral responses was not detected.

    How does a caller's anger, fear and sadness affect operators' decisions in emergency calls?2018Inngår i: International Review of Social Psychology, ISSN 2397-8570, Vol. 31, nr 1, artikkel-id 89Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We studied how emergency operators' interpretation of callers' anger, fear, and sadness influenced emergency assessments in 146 authentic emergency calls. All emergency calls need to be decided on quickly and operators discriminated emotional expressions, by separating fear from other emotions across help need levels. Using path analysis and structural equation modeling, caller's fear, as opposed to expressions of anger and sadness, showed both direct and indirect effects on the intention to provide help. Based on the findings, emergency operators are argued to actively incorporate callers' expressions into emergency decisions, rather than peripherally processing emotional expression. Such findings allow for a discussion on the interpersonal effects of emotional expressions and, more practically, how fast help will be able to arrive to the location of the emergency. © 2018 Ubiquity Press Ltd.

    Synthesis and characterization of Mo- and W-based atomic laminates2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Mn+1AXn (MAX) phases are inherently nanolaminated compounds based on transition metals (M), A group elements (A), and carbon or/and nitrogen (X), which exhibit a unique combination of ceramic and metallic properties. My thesis work has focused on exploring novel MAX phase chemistries, including elemental combinations beyond those traditionally used for MAX phases, and their graphene-analogous 2D counterpart, MXenes.  

    The first part of the thesis investigates Mo-based MAX phases, which are among the least studied, despite indication of superconducting properties and potential for derivation of Mo-based MXenes. Initially, I performed theoretical calculations focused on evaluation of phase stability of the Mon+1GaCn MAX phases, and synthesized the predicted stable Mo2GaC in thin film form using DC magnetron sputtering. Close to phase pure epitaxial films were grown at ~590 °C, and electrical resistivity measurements using a four-point probe technique suggest a superconducting behavior with a critical temperature of ~7 K. The follow-up of this work, was synthesis of a new MAX related material, Mo2Ga2C, also by means of DC magnetron sputtering. The theoretical predictions as well as the materials characterization by X-ray diffraction and neutron powder diffraction, suggested a Ga bilayer interleaved between a set of Mo2C blocks, arranged in a simple hexagonal structure.   

    It is known that selectively etching of the A-layer in a MAX phase, shown for A=Al, can lead to realization of a MXene. Hence, the next step in my research was to explore the possibility of etching of A=Ga in Mo2GaC as well as in Mo2Ga2C, targeting a Mo2C MXene, as motivated by theoretically proposed superior thermoelectric properties of this 2D material. While Mo2GaC did not allow removal of the A-layer, I showed that Mo2C MXene could be realized from etching Mo2Ga2C thin films, removing the Ga bilayer, in 50% hydrofluoric acid at a temperature of ~50 °C for a duration of ~3 h. Hence, the results did not only produce the first Mo-based MXene, it also showed that MXenes can be obtained for etching A-elements other than Al. This, in turn, increase the pathways for expanding the family of MXenes.    

    I thereafter set out to explore the magnetic properties resulting from Mn-alloying of the non-magnetic Mo2GaC MAX phase. For that purpose, (Mo,Mn)2GaC was synthesized using a  DC magnetron sputtering system with Ga and C as elemental targets and a 1:1 atomic ratio  Mo:Mn compound target. Heteroepitaxial films on MgO(111) substrates were grown at  ~530 °C, as confirmed by X-ray diffraction. Compositional analysis using energy dispersive X-ray spectroscopy showed a 2:1 ratio of the M- and A-elements and a 1:1 ratio for the Mo and Mn atoms in the film. Vibrating sample magnetometry was utilized to measure the magnetic behavior of the films, showing a magnetic response up to at least 300 K, and with a coercive field of 0.06 T, which is the highest reported for any MAX phase to date.  

    The second part of my research has been dedicated to realizing new MAX phase related, chemically ordered compounds and their MXene derivatives, and to initiate exploration of their properties. Materials synthesis was performed by pressureless bulk sintering, and inspired by theoretical calculations we showed evidence for a new so called o-MAX phase, Mo2ScAlC2, with an out-of-plane chemically ordered structure. It is the first experimentally verified Sc-containing MAX phase, which makes its corresponding MXene, Mo2ScC2, also presented in this work, the first MXene including Sc. Moreover, I discovered two so called i-MAX phases including W, (W2/3Sc1/3)2AlC and (W2/3Y1/3)2AlC, which display in-plane chemical ordering in the M-layer. Furthermore, both was shown to allow synthesis of their corresponding 2D counterpart; W1.33C MXene, with ordered vacancies.  Initial test on these novel MXenes showed a high potential for hydrogen evolution reaction.  

    Altogether, I have in my thesis work realized 6 novel MAX phases and related materials, and have shown evidence for 4 new MXenes. These materials inspire a wide range of future studies, with respect to fundamental properties as well as potential for future applications.

    Pollinator-mediated selection and the evolution of floral traits in orchids2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    In this thesis, I combined manipulations of traits and pollination environment with analysis of phenotypic selection to examine causes of variation in strength and mode of selection on floral traits, and I conducted a reciprocal sowing experiment to test for local adaptation in germination success. I tested the following predictions (1) the opportunity for selection, and the strength of pollinator-mediated and net selection increase with increasing pollen limitation, (2) the effects of traits affecting pollinator attraction and traits affecting pollination efficiency are non-additive and this leads to pollinator-mediated correlational selection, (3) the effects of spur length on pollen removal, pollen receipt, and female fitness differ between populations with short-tongued and populations with long-tongued pollinators, and (4) local adaptation at the stage of germination contributes to the maintenance of ecotypes growing in grasslands and woodlands, respectively.

    A study including natural populations of 12 orchid species that varied widely in pollen limitation showed that opportunity for selection, pollinator-mediated selection and net selection were all positively related to pollen limitation, whereas non-pollinator-mediated selection was not. In the moth-pollinated orchid Platanthera bifolia, experimental reductions of plant height and spur length decreased pollen removal, pollen receipt and fruit production, but non-additive effects were not detected. Effects of plant height translated into pollinator-mediated selection for taller plants via female fitness, but there was no current pollinator-mediated selection on spur length. An experiment using artificial nectar spurs demonstrated that in P. bifolia pollen receipt saturated at shorter spur length in a population with short-tongued pollinators than in a population with a long-tongued pollinator. Effects of spur length on pollen receipt did not translate into current pollinator-mediated selection indicating that also plants with the shortest spurs for the most part received sufficient pollen for full seed set. Reciprocal sowing of seeds from grassland and woodland populations detected no evidence of local adaptation at the germination stage between ecotypes of P. bifolia.

    Taken together, the results illustrate how a combination of trait manipulation and analysis of strength and causes of selection can throw light on both the functional and adaptive significance of trait variation within and among natural populations.

    Unintentional Childhood Injuries in Urban and Rural Ujjain, India: A Community-Based Survey2018Inngår i: Children (Basel), ISSN 2227-9067, Vol. 5, nr 2, artikkel-id 23Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Injuries are a major global public health problem. There are very few community-based studies on childhood injury from India. The objective of this cross-sectional, community-based survey was to identify the incidence, type, and risk factors of unintentional childhood injuries. The study was done in seven villages and ten contiguous urban slums in Ujjain, India. World Health Organization (WHO) tested tools and definitions were used for the survey, which included 2518 households having 6308 children up to 18 years of age, with 2907 children from urban households and 3401 from rural households. The annual incidence of all injuries was 16.6%, 95% Confidence Interval 15.7-17.5%, (n = 1049). The incidence was significantly higher among boys compared to girls (20.2% versus 12.7%, respectively), was highest in age group 6-10 years of age (18.9%), and in urban locations (17.5%). The most commonly identified injury types were: physical injuries (71%), burns (16%), poisonings (10%), agriculture-related injuries (2%), near drowning (2%), and suffocations (2%). The most common place of injury was streets followed by home. The study identified incidence of different types of unintentional childhood injuries and factors associated with increased risk of unintentional injuries. The results can help in designing injury prevention strategies and awareness programs in similar settings.

    Determining and Optimizing the Current and Magnetic Field Dependence of Spin-Torque and Spin Hall Nano-Oscillators: Toward Next-Generation Nanoelectronic Devices and Systems2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Spin-torque and spin Hall nano-oscillators are nanoscale devices (about 100 nm)capable of producing tunable broadband high-frequency microwave signals ranging from 0.1 GHz to over 65 GHz that several research groups trying to reach up to200 - 300 GHz. Their development is ongoing for applications in high-frequency nanoelectronic devices and systems, such as mobile phones, wireless networks, base stations, vehicle radars and even medical applications.

    This thesis covers a wide range of characterizations of spin-torque and spin Hall nano-oscillator devices that aim to investigate their current and magnetic field dependency, as well as to suggest improvements in these devices to optimize their application in spintronics and magnonics. The work is primarily based on experimental methods for characterizing these devices by building up new measurement systems, but it also includes numerical and micromagnetic simulations.

    Experimental techniques: In order to characterize the fabricated nanodevices in a detailed and accurate manner through their electrical and microwave responses, new measurement systems capable of full 3D control over the external magnetic fields will be described. In addition, a new method of probing an operational device using magnetic force microscopy (MFM) will be presented.

    Spin-torque nano-oscillators: We will describe remarkable improvements in the performance of spin-torque nano-oscillators (STNOs) that enhance their integration capability with applications in microwave systems. In nanocontact (NC-)STNOs made from a conventional spin-valve stack, though with thicker bottom electrodes, it is found the auto-oscillations can be excited with higher frequencies at lower threshold currents, and with higher output powers. We also find that this idea is useful for tuning spin-wave resonance and also controlling the thermal budget. Furthermore, a detailed study of magnetic droplet solitons and spin-wave dynamics in NC-STNOs will be described. Finally, we demonstrate ultra-high frequency tunability in low-current STNOs based on perpendicular magnetic tunnel junctions(p-MTJs).

    Spin Hall nano-oscillators: Characterizations of spin Hall nano-oscillator(SHNO) devices based on different structures and materials with both conventional and novel methods will be described. A detailed study of the current, temperature, and magnetic field profiles of nanogap SHNOs will be presented. In addition, we show the current and magnetic field dependence of nanoconstriction-based SHNOs.Moreover, it is shown that multiple SHNOs can be serially synchronized, thereby increasing their output power and enhancing the usage of these devices in applications such as neuromorphic computing. We show synchronization of multiple nanoconstriction SHNOs in the presence of a low in-plane magnetic field. Finally, there is a demonstration of the results of a novel method for probing an operationalSHNO using MFM.

    Strategists in the intersection of logics: A study of job advertisements in the Swedish municipal administration2015Rapport (Annet vitenskapelig)
    Abstract [en]

    This report is a study of how public administrators responsible for horizontal perspectives in Swedish local government are handling their role as bureaucrats and political promoters. Gender equality, public health, human rights, rights of children, and environmental protection are examples of perspectives which local authorities are obliged to take into consideration when making political decisions. In order to ensure this, certain strategists are appointed who are supposed to work across all sectors promoting the values and goals of their specific perspective. The role of these strategists contains several paradoxes and complexities.

    NON-ASSOCIATIVE ORE EXTENSIONS2018Inngår i: Israel Journal of Mathematics, ISSN 0021-2172, E-ISSN 1565-8511, Vol. 224, nr 1, s. 263-292Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We introduce non-associative Ore extensions, S = R[X; sigma, delta], for any non-ssociative unital ring R and any additive maps sigma, delta : R -> R satisfying sigma(1) = 1 and delta(1) = 0. In the special case when delta is either left or right R-delta-linear, where R-delta = ker(delta), and R is delta-simple, i.e. {0} and R are the only delta-invariant ideals of R, we determine the ideal structure of the non-associative differential polynomial ring D = R[X; id(R),delta]. Namely, in that case, we show that all non-zero ideals of D are generated by monic polynomials in the center Z(D) of D. We also show that Z(D) = R-delta[p] for a monic p is an element of R-delta [X], unique up to addition of elements from Z(R)(delta) . Thereby, we generalize classical results by Amitsur on differential polynomial rings defined by derivations on associative and simple rings. Furthermore, we use the ideal structure of D to show that D is simple if and only if R is delta-simple and Z(D) equals the field R-delta boolean AND Z(R). This provides us with a non-associative generalization of a result by Oinert, Richter and Silve-strov. This result is in turn used to show a non-associative version of a classical result by Jordan concerning simplicity of D in the cases when the characteristic of the field R-delta boolean AND Z(R) is either zero or a prime. We use our findings to show simplicity results for both non-associative versions of Weyl algebras and non-associative differential polynomial rings defined by monoid/group actions on compact Hausdorff spaces.

    ”Den nya svenskinspirerade föräldrapenningen har haft avsedd verkan”: En studie av den tyska föräldraförsäkringens förändring ur ett jämställdhetsperspektiv2010Rapport (Annet vitenskapelig)
    Abstract [en]

    It is argued that political-administrative organizations are becoming increasingly complex with more horizontal governance required. In Swedish municipal administration, there is a group of administrators assigned the task of monitoring and promoting strategic topics that should be integrated horizontally within the organization. Examples of strategic topics are sustainability, safety/security, diversity, children/youth, public health, human rights, and gender equality. In the thesis, these administrators are called cross-sector strategists. The purpose of this dissertation is to explore how cross-sector strategists become a part of the political-administrative organization when representing, enacting, and reflecting on values in the undertaking of their formal posts. They are situated between the tradition of vertical governance, with formal procedures and hierarchy as its foundation, and the tradition of horizontal governance, with informal networks and deliberation as its foundation. Previous research has shown that this is likely to give rise to value conflicts, and the question is if cross-sector strategists experience value conflicts, and if so, how they cope with them. The cross-sector strategists are studied in this thesis from the perspective of situated agency – focusing on both the contextual expectations of the cross-sector strategists and on their internal reflections to solve value conflicts – in order to explore their process of becoming a part of the local government administration. A mixed-methods design is applied, containing analysis of job advertisements for cross-sector strategists, public managers, and social workers; in-depth interviews with cross-sector strategists; and a survey of professional networks for cross-sector strategists. The results show that cross-sector strategists are subjects to ambivalent and often-contradictory contextual expectations. Cross-sector strategists use the ambivalence of their work for their strategic purposes, and such ambivalence allows them to reframe their topics, their methods, their arguments, and their identity according to current situation in order to increase the impact of their assigned topics and diminish the inner conflict of wanting to be both a responsive bureaucrat and an active lobbyist. Combining these two dedications requires them to be highly reflexive and flexible actors. The outcome of cross-sector strategists’ coping with value conflicts can be interpreted in two ways: 1) as if the cross-sector strategists are a formal tool to safeguard crucial democratic and ethical values due to the cross-sector strategists’ method of sneaking the strategic policy areas into the organization. Or 2) as a to democracy risky administrative behavior in the long-term due to the disguising of value conflicts and diminished possibilities to process these value conflicts

    Potentials for reducing the health and climate impacts of residential biomass combustion in the Nordic countries2018Bok (Annet vitenskapelig)
    Abstract [en]

    Residential biomass combustion is a major source of PM2.5 and SLCP (Short Lived Climate Pollutants) emissions in Denmark, Finland and Sweden. SLCPs and PM2.5 have impact on climate, environment and health. When developing strategies for reduced emissions, reliable information on current emissions and assessments for how they can be reduced is essential. This report presents recommendations for how to further improve national activity data collection procedures for less uncertain emission inventory results. It also presents scenario results with estimated technical potentials for reduced emissions of SLCPs and PM2.5 from residential biomass combustion, transformed into potential impact on health and climate effects in 2035.

    Forward to a Promising Future2018Inngår i: Conference proceedings COORDINATION 2018, 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In many actor-based programming models, asynchronous method calls communicate their results using futures, where the fulfilment occurs under-the-hood. Promises play a similar role to futures, except that they must be explicitly created and explicitly fulfilled; this makes promises more flexible than futures, though promises lack fulfilment guarantees: they can be fulfilled once, multiple times or not at all. Unfortunately, futures are too rigid to exploit many available concurrent and parallel patterns. For instance, many computations block on a future to get its result only to return that result immediately (to fulfil their own future). To make futures more flexible, we explore a construct, forward, that delegates the responsibility for fulfilling the current implicit future to another computation. Forward reduces synchronisation and gives futures promise-like capabilities. This paper presents a formalisation of the forward construct, defined in a high-level source language, and a compilation strategy from the high-level language to a low-level, promised-based target language. The translation is shown to preserve semantics. Based on this foundation, we describe the implementation of forward in the parallel, actor-based language Encore, which compiles to C.

    Prompt atmospheric neutrino flux in perturbative QCD and its theoretical uncertainties2017Inngår i: XXVII International Conference on Neutrino Physics and Astrophysics (Neutrino2016), Institute of Physics Publishing (IOPP), 2017, artikkel-id 012117Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Using the most recent PDFs and the cosmic ray spectrum, we evaluate the charm/bottom induced prompt atmospheric muon neutrino fluxes including nuclear corrections. We investigate their impact in perturbative QCD and estimate the comprehensive uncertainties from other various factors. The prompt atmospheric tau neutrino fluxes are also presented.
