  • Accelerometer derived physical activity and subclinical coronary and carotid atherosclerosis : cross-sectional analyses in 22 703 middle-aged men and women in the SCAPIS study
  • 2023
  • In: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 13:11
  • Journal article (peer-reviewed)abstract
    • OBJECTIVES: The aim included investigation of the associations between sedentary (SED), low-intensity physical activity (LIPA), moderate-to-vigorous intensity PA (MVPA) and the prevalence of subclinical atherosclerosis in both coronaries and carotids and the estimated difference in prevalence by theoretical reallocation of time in different PA behaviours.DESIGN: Cross-sectional.SETTING: Multisite study at university hospitals.PARTICIPANTS: A total of 22 670 participants without cardiovascular disease (51% women, 57.4 years, SD 4.3) from the population-based Swedish CArdioPulmonary bioImage study were included. SED, LIPA and MVPA were assessed by hip-worn accelerometer.PRIMARY AND SECONDARY OUTCOMES: Any and significant subclinical coronary atherosclerosis (CA), Coronary Artery Calcium Score (CACS) and carotid atherosclerosis (CarA) were derived from imaging data from coronary CT angiography and carotid ultrasound.RESULTS: High daily SED (>70% ≈10.5 hours/day) associated with a higher OR 1.44 (95% CI 1.09 to 1.91), for significant CA, and with lower OR 0.77 (95% CI 0.63 to 0.95), for significant CarA. High LIPA (>55% ≈8 hours/day) associated with lower OR for significant CA 0.70 (95% CI 0.51 to 0.96), and CACS, 0.71 (95% CI 0.51 to 0.97), but with higher OR for CarA 1.41 (95% CI 1.12 to 1.76). MVPA above reference level, >2% ≈20 min/day, associated with lower OR for significant CA (OR range 0.61-0.67), CACS (OR range 0.71-0.75) and CarA (OR range 0.72-0.79). Theoretical replacement of 30 min of SED into an equal amount of MVPA associated with lower OR for significant CA, especially in participants with high SED 0.84 (95% CI 0.76 to 0.96) or low MVPA 0.51 (0.36 to 0.73).CONCLUSIONS: MVPA was associated with a lower risk for significant atherosclerosis in both coronaries and carotids, while the association varied in strength and direction for SED and LIPA, respectively. If causal, clinical implications include avoiding high levels of daily SED and low levels of MVPA to reduce the risk of developing significant subclinical atherosclerosis.

  • Body weight at age 20 and in midlife is more important than weight gain for coronary atherosclerosis: Results from SCAPIS.
  • 2023
  • In: Atherosclerosis. - : Elsevier BV. - 1879-1484 .- 0021-9150. ; 373, s. 46-54
  • Journal article (peer-reviewed)abstract
    • Elevated body weight in adolescence is associated with early cardiovascular disease, but whether this association is traceable to weight in early adulthood, weight in midlife or to weight gain is not known. The aim of this study is to assess the risk of midlife coronary atherosclerosis being associated with body weight at age 20, body weight in midlife and body weight change.We used data from 25,181 participants with no previous myocardial infarction or cardiac procedure in the Swedish CArdioPulmonary bioImage Study (SCAPIS, mean age 57 years, 51% women). Data on coronary atherosclerosis, self-reported body weight at age 20 and measured midlife weight were recorded together with potential confounders and mediators. Coronary atherosclerosis was assessed using coronary computed tomography angiography (CCTA) and expressed as segment involvement score (SIS).The probability of having coronary atherosclerosis was markedly higher with increasing weight at age 20 and with mid-life weight (p<0.001 for both sexes). However, weight increase from age 20 until mid-life was only modestly associated with coronary atherosclerosis. The association between weight gain and coronary atherosclerosis was mainly seen in men. However, no significant sex difference could be detected when adjusting for the 10-year delay in disease development in women.Similar in men and women, weight at age 20 and weight in midlife are strongly related to coronary atherosclerosis while weight increase from age 20 until midlife is only modestly related to coronary atherosclerosis.

  • IMPACT OF BODY WEIGHT AT AGE 20 AND WEIGHT GAIN DURING ADULTHOOD ON MIDLIFE CORONARY ARTERY CALCIUM IN 15,000 MEN AND WOMEN : AN INTERIM ANALYSIS OF THE SWEDISH CARDIOPULMONARY BIOIMAGE STUDY
  • 2019
  • In: Journal of the American College of Cardiology. - : ELSEVIER SCIENCE INC. - 0735-1097 .- 1558-3597. ; 73:9, s. 1692-1692
  • Journal article (other academic/artistic)abstract
    • BackgroundElevated body weight in adolescence is strongly associated with early cardiovascular disease, but whether this association is traceable to weight in early adulthood, or to weight gain with subsequent high adult weight is not known. Using data from the Swedish CArdioPulmonary bioImage Study (SCAPIS), we investigated the association between weight at age 20, weight gain to midlife and coronary artery calcium score (CACS) at midlife.MethodsIn the first 15,810 participants in SCAPIS (mean age 58 years, 52% women), data on CACS at midlife, self-reported body weight at age 20 and weight at examination in SCAPIS were recorded.ResultsCACS in midlife was significantly higher with increasing weight at age 20 (p<0.001 for both sexes), and then increased with weight gain until midlife at all levels of body weight at age 20 after adjusting for age, height, smoking, alcohol intake, education level, exercise levels and LDL cholesterol. However, the association with weight gain was only significant in men (p = 0.047), not in women (p=0.474). No significant interaction was seen between weight at age 20 and midlife weight with CACS. The effect of weight at age 20 on CACS was significantly more marked in men than in women, as was the effect of weight gain (p<0.001 for both interactions).ConclusionWeight at age 20 and weight gain to midlife were both related to CACS, but much more markedly so in men than in women, indicating a generally larger effect of both early adult weight and further weight gain until midlife on CACS in men, compared to women.

  • Anisotropic Elastic-Viscoplastic Properties at Finite Strains of Injection-Moulded Low-Density Polyethylene
  • 2018
  • In: Experimental mechanics. - : Springer New York LLC. - 0014-4851 .- 1741-2765. ; 58:1, s. 75-86
  • Journal article (peer-reviewed)abstract
    • Injection-moulding is one of the most common manufacturing processes used for polymers. In many applications, the mechanical properties of the product is of great importance. Injection-moulding of thin-walled polymer products tends to leave the polymer structure in a state where the mechanical properties are anisotropic, due to alignment of polymer chains along the melt flow direction. The anisotropic elastic-viscoplastic properties of low-density polyethylene, that has undergone an injection-moulding process, are therefore examined in the present work. Test specimens were punched out from injection-moulded plates and tested in uniaxial tension. Three in-plane material directions were investigated. Because of the small thickness of the plates, only the in-plane properties could be determined. Tensile tests with both monotonic and cyclic loading were performed, and the local strains on the surface of the test specimens were measured using image analysis. True stress vs. true strain diagrams were constructed, and the material response was evaluated using an elastic-viscoplasticity law. The components of the anisotropic compliance matrix were determined together with the direction-specific plastic hardening parameters. © 2017 The Author(s)

  • Self‐reported documentation of goals and outcomes of nutrition care : A cross‐sectional survey study of Scandinavian dietitians
  • 2023
  • In: Scandinavian Journal of Caring Sciences. - : John Wiley & Sons. - 0283-9318 .- 1471-6712. ; 37:2, s. 472-485
  • Journal article (peer-reviewed)abstract
    • BackgroundThe documentation of goals and outcomes of nutrition care in Electronic Health Records is insufficient making further exploration of this of particular interest. Identifying common features in documentation practice among Scandinavian dietitians might provide information that can support improvement in this area.AimsTo explore the associations between clinical dietitians' self-reported documentation of patients' goals and outcomes and demographic factors, self-reported implementation of the systematic framework the Nutrition Care Process 4th step (NCP) and its associated terminology, and factors associated with the workplace.MethodsData from a cross-sectional study based on a previously tested web-based survey (INIS) disseminated in 2017 to dietitians in Scandinavia (n = 494) was used. Respondents were recruited through e-mail lists, e-newsletters and social media groups for dietitians. Associations between countries regarding the reported documentation of goals and outcomes, implementation levels of the NCP 4th step, demographic information and factors associated with the workplace were measured through Chi-square test. Associations between dependent- and independent variables were measured through logistic regression analysis.ResultsClinically practicing dietitians (n = 347) working in Scandinavia, Sweden (n = 249), Norway (n = 60), Denmark (n = 38), who had completed dietetic education participated. The reported documentation of goals and outcomes from nutrition intervention was highly associated with the reported implementation of NCP 4th step terminology (OR = 5.26; p = 0.009, OR = 3.56; p = 0.003), support from the workplace (OR = 4.0, p < 0.001, OR = 8.89, p < 0.001) and area of practice (OR = 2.02, p = 0.017). Years since completed dietetic training and educational level did not have any significant associations with documentation practice regarding goals and outcomes.ConclusionFindings highlight strong associations between the implementation of the NCP 4th step terminology and the documentation of goals and outcomes. Strategies to support dietitians in using standardized terminology and the development of tools for comprehensive documentation of evaluation of goals and outcome are required.

  • WARA-PS : a research arena for public safety demonstrations and autonomous collaborative rescue robotics experimentation
  • 2021
  • In: Autonomous Intelligent Systems. - : Springer Nature. - 2730-616X. ; 1:1
  • Journal article (peer-reviewed)abstract
    • A research arena (WARA-PS) for sensing, data fusion, user interaction, planning and control of collaborative autonomous aerial and surface vehicles in public safety applications is presented. The objective is to demonstrate scientific discoveries and to generate new directions for future research on autonomous systems for societal challenges. The enabler is a computational infrastructure with a core system architecture for industrial and academic collaboration. This includes a control and command system together with a framework for planning and executing tasks for unmanned surface vehicles and aerial vehicles. The motivating application for the demonstration is marine search and rescue operations. A state-of-art delegation framework for the mission planning together with three specific applications is also presented. The first one concerns model predictive control for cooperative rendezvous of autonomous unmanned aerial and surface vehicles. The second project is about learning to make safe real-time decisions under uncertainty for autonomous vehicles, and the third one is on robust terrain-aided navigation through sensor fusion and virtual reality tele-operation to support a GPS-free positioning system in marine environments. The research results have been experimentally evaluated and demonstrated to industry and public sector audiences at a marine test facility. It would be most difficult to do experiments on this large scale without the WARA-PS research arena. Furthermore, these demonstrator activities have resulted in effective research dissemination with high public visibility, business impact and new research collaborations between academia and industry.

  • Healthy eating as conceptualized in referral responses to Sweden’s updated dietary guidelines: excluding the complexity of everyday life
  • 2017
  • Conference paper (other academic/artistic)abstract
    • National Dietary Guidelines have been published in many countries to support healthier food habits among the public. In Sweden, the guidelines are produced in a process involving experts and stakeholders under the responsibility of the National Food Agency. Stakeholder perspectives on the concept of state dietary advice was explored in this study, by analyzing 40 referral responses on updated guidelines in Sweden 2015. The study focused on ideas about how state dietary advice should be framed and what it should be based on. Thematic analysis was used and resulted in two main themes. 'Securing scientifically proven advice' represented a perspective of the guidelines as to be scientifically correct and verified, and built upon an underlying assumption to present an objective and optimal composition of foods and nutrients that will fit all. Arguments based on nutritional reductionism could be seen, which gave a delimited idea of what healthy food is. 'Getting the message across' represented a perspective of the guidelines to be easily understood by and inclusive to the end user. Clarity in advice was seen to be reached by explaining difficult words, defining amounts and exact mechanisms of why something is a good choice. Also this perspective added to excluding other values of food, especially qualitative ones. The construction of a healthy diet in these remittance responses builds upon a notion of an ideal diet composed on the basis of the best scientific proof and clearly presented so as to be easily understood and practiced. It was clearly based on an individualistic behavioral view making the individual responsible to make informed and good choices for a healthy diet. This approach may be questioned, as it is too simplified to include the complex reality of everyday life.

  • Public expressions of trust and distrust in governmental dietary advice in Sweden
  • 2019
  • In: Qualitative Health Research. - : SAGE Publications. - 1049-7323 .- 1552-7557. ; 29:8, s. 1161-1173
  • Journal article (peer-reviewed)abstract
    • We examine public trust and distrust in governmental food and nutrition authorities, through analyzing 727 letters sent electronically to the Swedish National Food Agency by lay people. Using thematic analysis, four themes were developed, defining public expressions of trust and distrust in official dietary advice. Trust was expressed as (a) seeking to confirm and clarify dietary advice, or (b) seeking official arbitration between competing dietary advice. Distrust was expressed as (c) questioning and scrutinizing dietary advice, or (d) protesting and resisting dietary advice. Notably, expressions of distrust employed discursive practices that both mirrored authoritative discourses and subverted official advice, by appealing to scientific language and 'alternative' evidence. All letters positioned the agency as the ultimate authority on healthy eating; notwithstanding whether the agency’s advice was to be followed or resisted. Thus, the letters revealed how the same authoritative discourses can simultaneously be a site of public trust and distrust.

  • Stakeholder responses to governmental dietary guidelines : Challenging the status quo, or reinforcing it?
  • 2018
  • In: British Food Journal. - : Emerald Group Publishing Limited. - 0007-070X .- 1758-4108. ; 120:3, s. 613-624
  • Journal article (peer-reviewed)abstract
    • PurposeThe purpose of this paper is to explore how stakeholders in the food and nutrition field construct and conceptualise “appropriate” national dietary advice.Design/methodology/approachIn total, 40 voluntarily written stakeholder responses to updated official dietary guidelines in Sweden were analysed thematically. The analysis explored the logics and arguments employed by authorities, interest organisations, industry and private stakeholders in attempting to influence the formulation of dietary guidelines.FindingsTwo main themes were identified: the centrality of anchoring advice scientifically and modes of getting the message across to the public. Stakeholders expressed a view of effective health communication as that which is nutritionally and quantitatively oriented and which optimises individuals’ capacities to take action for their own health. Their responses did not offer alternative framings of how healthy eating could be practiced but rather conveyed an understanding of dietary guidelines as documents that provide simplified answers to complex questions.Practical implicationsPolicymakers should be aware of industrial actors’ potential vested interests and actively seek out other stakeholders representing communities and citizen interests. The next step should be to question the extent to which it is ethical to publish dietary advice that represents a simplified way of conceptualising behavioural change, and thereby places responsibility for health on the individual.Originality/valueThis research provides a stakeholder perspective on the concept of dietary advice and is among the first to investigate referral responses to dietary guidelines.

  • Process-Induced Structures of Injection-Molded High-Density Polyethylene─Combining X-ray Scattering and Finite Element Modeling
  • 2024
  • In: ACS Applied Polymer Materials. - 2637-6105. ; 6:8, s. 4852-4864
  • Journal article (peer-reviewed)abstract
    • The success of plastics heavily relies on fast melt processing methods used for large-scale industrial manufacturing, including injection molding. The hierarchical structure of the solid polymer depends on material selection combined with processing conditions, making mechanical properties of the injection molded part difficult to predict. Here we show how scanning small- and wide-angle X-ray scattering, birefringence microscopy, and polarized light optical microscopy can be combined with injection molding simulations to shed light on the correlation between the polymer morphology of high-density polyethylene and processing conditions. The scattering data revealed that the complex layered structure highly depends on the pressure during the holding phase of injection molding. Furthermore, we identified specific work of flow as a main parameter to capture the changes in morphology induced by varying the process settings. Overall, a good agreement was found between experimental data and the computational simulations, suggesting that computational simulations can be further used to predict the multiphase morphology of injection molded parts.

  • Scanning Small-Angle X-ray Scattering of Injection-Molded Polymers: Anisotropic Structure and Mechanical Properties of Low-Density Polyethylene
  • 2023
  • In: ACS Applied Polymer Materials. - 2637-6105. ; 5:8, s. 6429-6440
  • Journal article (peer-reviewed)abstract
    • Injection molding is known to create a layered anisotropicmorphologyacross the sample thickness due to varying shear and cooling ratesduring the manufacturing process. In this study, scanning small-angleX-ray scattering was used to visualize and quantify the distributionof hierarchical structures present in injection-molded parts of low-densitypolyethylene (LDPE) with varying viscosities. By combining scatteringdata with results from injection molding simulations and tensile testing,we find that oriented shish-kebab structures, as well as elongatedspherulite structures consisting of semicrystalline ellipsoids, contributeto high ultimate tensile strength along the flow direction. Furthermore,we show that a higher degree of orientation is found close to theinjection gate and in LDPE with higher viscosity, consequently fromelevated shear and cooling rates present during the injection moldingprocess.

  • Postural stability, physical activity, aerobic capacity and their associations for young people with and without intellectual disabilities
  • 2014
  • In: European Journal of Adapted Physical Activity. - 1803-3857. ; 7:1, s. 22-30
  • Journal article (other academic/artistic)abstract
    • Previous studies show that people with intellectual disability (ID) appear to have impaired postural stability, a lower level of physical activity, and lower aerobic capacity compared to persons without ID, limitations that could affect their health. This study investigates these physical functions and their associations in a group of young people with ID compared to an age-matched group without ID. In total, this cross-sectional study included 106 high school students (16-20 years): 57 students with mild to moderate ID and 49 agematched students without ID (control group). Tests were performed for postural stability, level of physical activity, and aerobic capacity. Both females and males with ID had significantly lower estimated maximum oxygen uptake (l O2/min) (p< 0.001 for females and p=0.004 for males) and a lower aerobic capacity expressed relative to body weight (ml O2/ kg*min) (p< 0.001 for females and p=0.012 for males) compared to age-matched peers. Analyses of associations were made using the Pearson’s correlation coefficient and multivariate linear regression analysis. No significant associations could be found. Physical status appears impaired for young people with ID and functions, such as postural stability, should be evaluated separately

  • Dorsomedial prefrontal theta burst stimulation to treat anhedonia, avolition, and blunted affect in schizophrenia or depression : a randomized controlled trial
  • 2021
  • In: Journal of Affective Disorders. - : Elsevier. - 0165-0327 .- 1573-2517. ; 290, s. 308-315
  • Journal article (peer-reviewed)abstract
    • BackgroundIntermittent theta burst stimulation (iTBS) over the dorsomedial prefrontal cortex (DMPFC) has shown promise in open-label trials of depression.MethodsIn this randomized, double-blind, sham controlled trial we evaluate iTBS over the DMPFC for anhedonia, avolition, and blunted affect in patients with schizophrenia or depression. Active iTBS was delivered over the DMPFC with 1200 pulses per session, twice daily over ten weekdays at target intensity with an angled figure-of eight coil. Sham condition comprised the magnetically shielded side of the coil and simultaneous transcutaneous electrical nerve stimulation. Primary outcome was change on the Clinical Assessment Interview for Negative Symptoms (CAINS).ResultsTwenty-eight patients were randomized to active iTBS and 28 to sham. Mean (standard deviation) change in CAINS score from baseline to the day after last treatment was -5.3 (8.1) in active iTBS and -2.1 (7.1) in sham. A linear model showed no significant effect of treatment, accounting for baseline scores p=.088. Sub analyses per diagnostic group showed a significant effect in patients with depression, p=.038, but not in the schizophrenia group, p=.850. However, overall depressive symptoms did not change significantly in patients with depression. There were three serious adverse events, all in the sham group.LimitationsPossibly too short treatment course and few patients with schizophrenia.ConclusionIn this first transdiagnostic randomized controlled trial of iTBS over DMPFC for anhedonia, avolition, and blunted affect it can be concluded that it was generally tolerable and safe but only more effective than sham in the subgroup of patients with depression.

  • Improving gait classification in horses by using inertial measurement unit (IMU) generated data and machine learning
  • 2020
  • In: Scientific Reports. - : Springer Nature. - 2045-2322. ; 10:1
  • Journal article (peer-reviewed)abstract
    • For centuries humans have been fascinated by the natural beauty of horses in motion and their different gaits. Gait classification (GC) is commonly performed through visual assessment and reliable, automated methods for real-time objective GC in horses are warranted. In this study, we used a full body network of wireless, high sampling-rate sensors combined with machine learning to fully automatically classify gait. Using data from 120 horses of four different domestic breeds, equipped with seven motion sensors, we included 7576 strides from eight different gaits. GC was trained using several machine-learning approaches, both from feature-extracted data and from raw sensor data. Our best GC model achieved 97% accuracy. Our technique facilitated accurate, GC that enables in-depth biomechanical studies and allows for highly accurate phenotyping of gait for genetic research and breeding. Our approach lends itself for potential use in other quadrupedal species without the need for developing gait/animal specific algorithms.

  • Lateral movement of the saddle relative to the equine spine in rising and sitting trot on a treadmill
  • 2018
  • In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 13
  • Journal article (peer-reviewed)abstract
    • Saddle slip, defined as a progressive lateral displacement of the saddle during ridden exercise, has recently been given attention in the scientific press as a potential sign of lameness. The aim of this study was to objectively quantify the normal lateral movement (oscillations) of the saddle relative to the horse in non-lame horses, and associate this movement to the movements of the horse and rider. Data from seven Warmblood dressage horses competing at Grand Prix (n = 6) or FEI Intermediate (n = 1) level, ridden by their usual riders, were used. Simultaneous kinetic, kinematic and saddle pressure measurements were conducted during sitting and rising trot on a force-measuring treadmill. The maximum lateral movement of the caudal part of the saddle relative to the horse's spine (MAX) was determined for each diagonal step. A mixed model was applied, with MAX as outcome, and T6 and S3 vertical position, rigid body rotation angles (roll, pitch, yaw) of the horse's and rider's pelvis, vertical ground reaction forces, saddle force, and rider position (rising in rising trot, sitting in rising trot or sitting in sitting trot) as explanatory variables. The least square means for MAX were 14.3 (SE 4.7) mm and 23.9 (SE 4.7) mm for rising and sitting in rising trot, and 20.3 (SE 4.7) mm for sitting trot. A 10 mm increase in maximum pelvic height at push off increased MAX by 1.4 mm (p<0.0001). One degree increase in rider pelvis roll decreased MAX 1.1 mm, and one degree increase in rider pelvis yaw increased MAX 0.7 mm (both p<0.0001). The linear relationships found between MAX and movements of both horse and rider implies that both horse and rider movement asymmetries are reflected in the lateral movements or oscillations of the saddle in non-lame horses.

  • In vitro and in vivo response to low-modulus PMMA-based bone cement
  • 2015
  • In: BioMed Research International. - : Hindawi Limited. - 2314-6133 .- 2314-6141.
  • Journal article (peer-reviewed)abstract
    • The high stiffness of acrylic bone cements has been hypothesized to contribute to the increased number of fractures encountered after vertebroplasty, which has led to the development of low-modulus cements. However, there is no data available on the in vivo biocompatibility of any low-modulus cement. In this study, the in vitro cytotoxicity and in vivo biocompatibility of two types of low-modulus acrylic cements, one modified with castor oil and one with linoleic acid, were evaluated using human osteoblast-like cells and a rodent model, respectively. While the in vitro cytotoxicity appeared somewhat affected by the castor oil and linoleic acid additions, no difference could be found in the in vivo response to these cements in comparison to the base, commercially available cement, in terms of histology and flow cytometry analysis of the presence of immune cells. Furthermore, the in vivo radiopacity of the cements appeared unaltered. While these results are promising, the mechanical behavior of these cements in vivo remains to be investigated.

  • First clinical experience of a ring-configured cadmium zinc telluride camera : A comparative study versus conventional gamma camera systems
  • 2024
  • In: Clinical Physiology and Functional Imaging. - 1475-0961. ; 44:1, s. 79-88
  • Journal article (peer-reviewed)abstract
    • BACKGROUND: A novel semiconductor cadmium zinc telluride (CZT) gamma camera system using a block sequential regularized expectation maximization (BSREM) reconstruction algorithm is now clinically available. Here we investigate how a multi-purpose ring-configurated CZT system can be safely applied in clinics and describe the initial optimization process.METHOD: Seventy-six patients (bone-, cardiac- and lung scan) were scanned on a conventional gamma camera (planar and/or single-photon emission computed tomography [SPECT]/SPECT-CT) used in clinical routine and on the ring-configurated CZT camera Starguide (GE Healthcare). These data were used to validate and optimize the Starguide system for routine clinical use.RESULTS: Comparable image quality for the Starguide system, to that of the conventional gamma camera, was achieved for bone scan (4 min/bed position [BP] using a relative difference prior [RDP] with gamma 2 and beta 0.4, along with 10 iterations and 10 subsets), cardiac scan (8 min [stress] and 3 min 20 s [rest] using median root prior [MRP] with beta 0.07 non attenuation corrected and 0.008 attenuation corrected and 50 interations and 10 subsets for both stress and rest) and lung scan (10 min [vent] and 5 min [perf] using RDP with gamma 0.5 and beta 0.03 [vent] and 0.02 [perf] and 20 interations and 10 subsets for both vent and perf).CONCLUSIONS: It was possible to transition from a conventional gamma camera to the Starguide system as part of the clinical routine, with acceptable image quality. Images from the Starguide system were deemed to be at least as good as those from a conventional gamma camera.

  • The structures of CyMe4-BTBP complexes of americium(III) and europium(III) in solvents used in solvent extraction, explaining their separation properties
  • 2015
  • In: Dalton Transactions. - : Royal Society of Chemistry (RSC). - 1477-9226 .- 1477-9234. ; 44:42, s. 18395-18402
  • Journal article (peer-reviewed)abstract
    • Separation of trivalent actinoid (An(III)) and lanthanoid (Ln(III)) ions is extremely challenging due to their similar ionic radii and chemical properties. Poly-aromatic nitrogen compounds acting as tetradentate chelating ligands to the metal ions in the extraction, have the ability to sufficiently separate An(III) from Ln(III). One of these compounds, 6,6'-bis(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-benzol[1,2,4]triazin-3-y l)-[2,2]bipyridine, CyMe4-BTBP, has proven to be resistant towards acidic environments and strong radiation from radioactive decomposition. EXAFS studies of the dicomplexes of CyMe4-BTBP with americium(III) and europium(III) in nitrobenzene, cyclohexanone, 1-hexanol, 1-octanol and malonamide (DMDOHEMA) in 1-octanol have been carried out to get a deeper understanding of the parameters responsible for the separation. The predominating complexes independent of solvent used are [Am(CyMe4-BTBP)(2)(NO3)](2+) and [Eu(CyMe4-BTBP)(2)](3+), respectively, which are present as outer-sphere ion-pairs with nitrate ions in the studied solvents with low relative permittivity. The presence of a nitrate ion in the first coordination sphere of the americium(III) complex compensates the charge density of the complex considerably in comparison when only outer-sphere ion-pairs are formed as for the [Eu(CyMe4-BTBP)(2)](3+) complex. The stability and solubility of a complex in a solvent with low relative permittivity increase with decreasing charge density. The [Am(CyMe4-BTBP)(2)(NO3)](2+) complex will therefore be increasingly soluble and stabilized over the [Eu(CyMe4-BTBP)(2)](3+) complex in solvents with decreasing relative permittivity of the solvent. The separation of americium(III) from europium(III) with CyMe4-BTBP as extraction agent will increase with decreasing relative permittivity of the solvent, and thereby also with decreasing solubility of CyMe4-BTBP. The choice of solvent is therefore a balance of a high separation factor and sufficient solubility of the CyMe4-BTBP ligand.

  • Accelerometer derived physical activity patterns in 27.890 middle‐aged adults : The SCAPIS cohort study
  • 2022
  • In: Scandinavian Journal of Medicine and Science in Sports. - : John Wiley & Sons. - 0905-7188 .- 1600-0838. ; 32:5, s. 866-880
  • Journal article (peer-reviewed)abstract
    • The present study aims to describe accelerometer-assessed physical activity (PA) patterns and fulfillment of PA recommendations in a large sample of middle-aged men and women, and to study differences between subgroups of socio-demographic, socio-economic, and lifestyle-related variables. A total of 27 890 (92.5% of total participants, 52% women, aged 50–64 years) middle-aged men and women with at least four days of valid hip-worn accelerometer data (Actigraph GT3X+, wGT3X+ and wGT3X-BT) from the Swedish CArdioPulmonary bioImage Study, SCAPIS, were included. In total, 54.5% of daily wear time was spent sedentary, 39.1% in low, 5.4% in moderate, and only 0.1% in vigorous PA. Male sex, higher education, low financial strain, born in Sweden, and sedentary/light working situation were related to higher sedentary time, but also higher levels of vigorous PA. High BMI and having multiple chronic diseases associated strongly with higher sedentary time and less time in all three PA intensities. All-year physically active commuters had an overall more active PA pattern. The proportion fulfilling current PA recommendations varied substantially (1.4% to 92.2%) depending on data handling procedures and definition used. Twenty-eight percent was defined as having an “at-risk” behavior, which included both high sedentary time and low vigorous PA. In this large population-based sample, a majority of time was spent sedentary and only a fraction in vigorous PA, with clinically important variations between subgroups. This study provides important reference material and emphasizes the importance of a comprehensive assessment of all aspects of the individual PA pattern in future research and clinical practice.

  • Undervisning med stöd av förproducerade material : Ett närmande av naturvetenskap i förskolan
  • 2022
  • Doctoral thesis (other academic/artistic)abstract
    • This thesis aims to develop an understanding of the possibilities and challenges pre-produced teaching materials present to teachers and the learning opportunities children are offered in teaching that uses such materials. To do this a study of preschool teachers and children from three preschool departments in Sweden was carried out. The study focuses on the preschool teachers’ descriptions of their planned teaching as well as their realization of their teaching when they use the pre-produced teaching material titled “Science and Technology for All”. The teacher guides to this material, used by the preschool teachers, are also examined. The study is based on a qualitative analysis of interviews, video observations and the teacher guides. The theoretical foundation is based on a pragmatic view from the ideas of John Dewey and the theoretical concepts ultimate and proximate purposes and continuity is used in the analysis.The results of the thesis show that, even though the preschool teachers drew on the same teaching material, they displayed three different teaching practices, each of which created different opportunities to learn natural science for the participating children. The results highlight specific teaching actions that appear to either promote or hinder children's opportunities for learning natural science. The results also show that the teacher guides are vague and ambiguous, thus opening the possibility of different interpretations regarding what should be focused on in the teaching. The study concludes by stressing the importance of clear and unambiguous teacher guides. The results of the study are relevant for teaching in preschool, and other early-years educational settings for example the early school years. The results also have a general validity across a wide range of subject areas.

  • Excited State Dynamics of Bistridentate and Trisbidentate Ru II Complexes of Quinoline-Pyrazole Ligands
  • 2019
  • In: Inorganic Chemistry. - : American Chemical Society (ACS). - 0020-1669 .- 1520-510X. ; 58:24, s. 16354-16363
  • Journal article (peer-reviewed)abstract
    • Three homoleptic ruthenium(II) complexes, [Ru(Q3PzH)3]2+, [Ru(Q1Pz)3]2+, and [Ru(DQPz)2]2+, based on the quinoline-pyrazole ligands, Q3PzH (8-(3-pyrazole)-quinoline), Q1Pz (8-(1-pyrazole)-quinoline), and DQPz (bis(quinolinyl)-1,3-pyrazole), have been spectroscopically and theoretically investigated. Spectral component analysis, transient absorption spectroscopy, density functional theory calculations, and ligand exchange reactions with different chlorination agents reveal that the excited state dynamics for Ru(II) complexes with these biheteroaromatic ligands differ significantly from that of traditional polypyridyl complexes. Despite the high energy and low reorganization energy of the excited state, nonradiative decay dominates even at liquid nitrogen temperatures, where triplet metal-to-ligand-charge-transfer emission quantum yields range from 0.7 to 3.8%, and microsecond excited state lifetimes are observed. In contrast to traditional polypyridyl complexes where ligand exchange is facilitated by expansion of the metal-ligand bonds to stabilize a metal-centered state, photoinduced ligand exchange occurs in the bidentate complexes despite no substantial MC state population, while the tridentate complex is extremely photostable despite an activated decay route, highlighting the versatile photochemistry of nonpolypyridine ligands. © 2019 American Chemical Society.

  • A Randomized Controlled Trial of the Effectiveness of Virtually Delivered Body Project (vBP) Groups to Prevent Eating Disorders
  • 2020
  • In: Journal of Consulting and Clinical Psychology. - : American Psychological Association (APA). - 0022-006X .- 1939-2117. ; 88:7, s. 643-656
  • Journal article (peer-reviewed)abstract
    • Objectives: To investigate the effectiveness of Body Project groups delivered virtually (vBP) by peer educators for prevention of eating disorders. Method: In a randomized controlled trial vBP groups (N = 149) were compared with a placebo (expressive writing, EW: N = 148) over 24-month follow-up and to a waitlist control condition (N = 146) over 6-month follow-up among females (15-20 years old) with body image concerns. The primary outcome was incidence of eating disorder onset over 2-year follow-up measured by blinded diagnostic interviews. Waitlist participants were offered the vBP after 6 months. Results: The incidence of eating disorders onset over 24 months follow up were 3 in vBP (2.0%) and 13 in EW (8.8%), a significant difference; Hazard Ratio (Experiment B) = 0.26, 95% confidence interval (CI) [0.075, 0.92], p = .037. Incidence of eating disorder onset in vBP participants was 77% less than in EW participants. The vBP participants generally showed significantly greater reduction in eating disorder symptoms, clinical impairment, body dissatisfaction, and internalization of thin ideal compared with the waitlist participants at postintervention and 6-month follow-up, and in eating disorder symptoms, restraint, body dissatisfaction, and internalization of thin ideal compared with the EW participants at postintervention, and 6-, 12-, 18-, or 24-months follow-up. EW participants reported significantly greater reduction in clinical impairment and body dissatisfaction at postintervention compared with the waitlist participants. Conclusions: The present reduction in the incidence of eating disorders is notable given that the intervention was implemented virtually, rather than in-person. The vBP might be a viable option for future evaluation of scalable prevention of eating disorders.

  • Inventering av asp : provfiske i Nedre Dalälven 2008
  • 2011
  • Reports (other academic/artistic)abstract
    •      Länsstyrelserna i Gävle och Uppsala län utförde med medfinansiering från Upplandsstiftelsen provfiske i Nedre Dalälven sommaren 2008 med målet att söka efter den hotade fiskarten asp ( Aspius aspius). Vid undersökningarna användes översiktsnät av typ Norden till standardiserade provfisken i kombination med nät med maskstorlekar avpassade till att fånga asp. Som positiv bieffekt av provfisket blev Bredforsens och Båtfors naturreservat inventerade vad gäller fiskefaunan, Vilket kan användas i arbetet med att ta fram en skötselplan och ett åtgärdsprogram för dessa områden.Den första lokalen för undersökningen var i Marma- området (Lanfjärden, Storfjärden, Källfjärden och Marmafjärden).Området är känt för sitt aspfiske och valdes även utifrån rapporter från lokalbefolkningen att det där påträffats asp under sommaren 2007.Följände arter fångades i Marmafjärden och närliggande områden vid provfisket 2008: abborre, björkna, braxen, gädda, gärs, gös, löja, mört och sutare. Det utfördes även provfisken i andra delar av Nedre Dalälven denna sommar där i stort sett samma arter fångades.Eftersom ingen asp påträffades vid Marmafjärden där de sista rapporterade fångsterna av arten gjort innan provfisket, så valdes efterföljande områden endast med syfte att maximera chansen att fånga asp. Ingen asp påträffades trots detta på någon av lokalerna under provfisket. Asp förekommer fortfarande i Dalälven, men är akut hotadFångster av asp har dock registrerats efter provfisket t ex: vid Båtfors och direkt nedströms Untra kraftverk, vilket medför bevis för att arten fortfarande förekommer i området. Det rör sig dessvärre om ett mycket litet bestånd asp fördelat på stora vattenvolymer. Resultatet av provfisket och efterföljande dokumentation är ett tydligt varningstecken på att arten finns kvar, men håller på att försvinna från sitt nordligaste utbredningsområde. Detta betyder att omedelbara åtgärder krävs för att främja och därmed rädda arten.Det finns två dominerade orsaker till minskningen av asp i Nedre Dalälven. Det är med största säkerhet vandringshindren och vår tids vattenreglering med allt lägre vattenflöden under viktiga perioder samt ”ryckigare ” vattenföring, vilket har påverkat arten mycket negativt. Aspen behöver fria vandringsvägar till reproduktionsområdena samt strömmande vatten för sin reproduktion. Det krävs högre vattenflöden och bättre reglar för vattenregleringen för att uppfylla gällande EU-direktiv. Man bör även satsa på information till allmänheten samt införa restriktioner för fiske, förslagsvis ett totalförbud för fångst av asp på försommaren då aspen leker.

  • Reassembling Local E-Government : A study of actors’ translations of digitalisation in public administration
  • 2017
  • Doctoral thesis (other academic/artistic)abstract
    • The digitalisation of society decidedly affects public administration. Swedish public administration has long worked with information technologies for an effective and improved management of public services. But new and increased use of information technologies in society poses new challenges. New demands on information security are increasing, while accessibility and transparency are important priorities in policies on digitalisation in public services. However, the central government’s ambitions and expectations with regard to digitalisation face a slow and hesitant implementation in local governments. There are important differences between municipalities in priorities, local needs, and implementation mechanisms in connection with e-government. In this thesis, I argue there is a need to reconsider the role of governance mechanisms in e-government. There is a need to understand local translations of national policies and technological developments in relation to the goals of more effective and legitimate public administration. The main purpose of this thesis is to analyse tensions that emerge in the implementation of egovernment in local public administration. On the basis of a constructivist and interpretivist approach, I have undertaken two empirical studies. One focuses on municipal administration of education in Linköping. The other focuses on a governance network on digitalisation policy in Östergötland. The studies are presented in four papers. The issues addressed in the papers are further analysed with a focus on four fields of tension, using network governance theory and translation theory. This shows that the implementation of e-government in local public administration is a tension-laden process. The four fields of tension relate to: different logics and dilemmas for adoption and implementation; concerns and ambiguities in a context of unclear organisational and institutional arrangements; concerns and resistance from professional users; and a reassessment of the meaning of security as a reference for the interpretation of information security. I contend that established managerial and evolutionary models of e-government leave important process-related aspects out of the analysis of change in public administration. The contribution of this thesis lies in its description and analysis of the four identified fields of tension. One significant implication of my analysis is that reassembling current  governance mechanisms in local public administration is crucial.

  • An indicator framework to guide food system sustainability transition – The case of Sweden
  • 2024
  • In: Environmental and Sustainability Indicators. - : Elsevier B.V.. - 2665-9727. ; 22
  • Journal article (peer-reviewed)abstract
    • Well-aligned food policies are needed at both national and international level to guide food system transformation towards sustainability. Rigorous indicator frameworks are essential in order to facilitate discussion of priorities, enable comparisons, assessment and progress monitoring, and ensure accountability. In this study, we develop a national framework for a sustainable food system, using Sweden as a case. Our framework, the Food System Sustainability House, advances the literature on sustainable food system frameworks in three distinct ways. Firstly, it is tailored to a specific national context (Sweden in our case); secondly, it distinguishes between impacts of domestic production arising within territorial boundaries and impacts related to Swedish consumption independent of country of origin; and thirdly, to facilitate policy priorities, it suggests how different dimensions of sustainability are interlinked at a conceptual level. From a scientific perspective, the Food System Sustainability House postulates the interlinkages between the societal objectives of the food system, the environmental foundations on which production takes place, and the economic system and governance which in the framework are suggested to function as enablers for an overall sustainable system. From a policy perspective, the framework provides a much-needed basis for assessing food system sustainability by suggesting indicators within a comprehensive set of sustainability themes at national level for monitoring distinct perspectives. It also provides the necessary basis for a discussion on how sustainability dimensions are interlinked.

  • Adaptation strategies of the Icelandic horse with induced forelimb lameness at walk, trot and tölt
  • 2024
  • In: Equine Veterinary Journal. - 0425-1644 .- 2042-3306. ; 56, s. 617-630
  • Journal article (peer-reviewed)abstract
    • Background and objective Lameness assessment in the gaited Icelandic horse is complex. We aimed to describe their kinematic and temporal adaptation strategies in response to forelimb lameness at walk, trot and tolt.Study designIn vivo experiment.Methods Ten clinically non-lame Icelandic horses were measured before and after reversible forelimb lameness induction. Upper body and limb kinematics were measured using 11 inertial measurement units mounted on the poll, withers, pelvis (tubera sacrale) and all four limbs and hoofs (Equimoves (R), 500 Hz). Horses were measured on a straight line at walk and trot in-hand and at walk, trot and tolt while ridden. Linear mixed models were used to compare baseline and lame conditions (random factor = 'horse'), and results are presented as the difference in estimated marginal means or percentage of change.Results Lameness induction significantly (p < 0.05) increased head vertical movement asymmetry at walk (HDmin/HDmaxHAND: 18.8/5.7 mm, HDmin/HDmaxRIDDEN: 9.8/0.3 mm) and trot (HDmin/HDmaxHAND: 18.1/7.8 mm, HDmin/HDmaxRIDDEN: 24.0/9.3 mm). At the tolt, however, HDmin did not change significantly (1.1 mm), but HDmax increased by 11.2 mm (p < 0.05). Furthermore, pelvis vertical movement asymmetry (PDmax) increased by 4.9 mm, sound side dissociation decreased (-8.3%), and sound diagonal dissociation increased (6.5%). Other temporal stride variables were also affected, such as increased stance duration of both forelimbs at walk, tolt and in-hand trot.Main limitations Only one degree of lameness (mild) was induced with an acute lameness model.Conclusions Classical forelimb lameness metrics, such as vertical head and withers movement asymmetry, were less valuable at tolt compared to walk and trot, except for HDmax. Therefore, it is advised to primarily use the walk and trot to detect and quantify forelimb lameness in the Icelandic horse.

  • Non-banked curved tracks influence movement symmetry in two-year-old Standardbred trotters
  • 2021
  • In: Equine Veterinary Journal. - : Wiley. - 0425-1644 .- 2042-3306.
  • Journal article (peer-reviewed)abstract
    • Background: Little is known regarding how trotting through curves affects locomotion symmetry in Standardbred trotters.Objectives: To investigate differences in objectively measured Standardbred trotter vertical motion symmetry between straight and non-banked, curved sections of oval trotting tracks during exercise warm-up, using a wireless inertial measurement unit (IMU) system.Study design: Cross-sectional, observational study.Methods: Sixteen horses were included. Mixed models were used to assess associations between symmetry, track segment (straight vs curve) and stride duration.Results: Significant results for forelimb parameters were dependent on interactions between track segments and stride duration. At mean stride duration (0.611 second), during the curved track segment horses showed a lower maximum vertical position of the head after push-off of the outside forelimb (estimate -2.3 mm, P < 0.0001, 95% CI -1.7 to -2.9) and higher minimum vertical position of the head during stance of the outside forelimb (estimate -1.8 mm, P < 0.0001, 95% CI -1.2 to -2.5) compared to straight track, mimicking outside forelimb impact and push-off asymmetry during track curves. For hindlimb parameters, during the curve there was a decreased downward motion of the pelvis during outer hindlimb stance (estimate-0.7 mm, P < 0.0001, 95% CI -0.4 to -1.0), mimicking outside hindlimb impact asymmetry.Main limitations: Horses were evaluated going in one direction only on the track (clockwise).Conclusions: Systematic differences between straight and curved track segments were found but did not fully correspond to previously described findings for horses lunged in circles. Effect sizes were overall small. Data in our study were collected from horses trotting on 1000 m tracks with curve radii of 80-85 m. On non-banked tracks of this size, collecting IMU symmetry data at jogging speeds without distinguishing between straight and curved parts is unlikely to adversely affect clinical decision-making.

  • Journal article (peer-reviewed)abstract
    • Graft copolymers with ionic backbones and hydrophobic fluorinated side chains have been prepared by using lithiated poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) as a macroinitiator for anionic polymerization of 4-fluorostyrene. After grafting of the poly(4-fluorostyrene) (PFS) side chains, the PPO backbone was selectively sulfonated using trimethylsilylchlorosulfonate under mild and controlled conditions. Microscopy of solvent cast membranes revealed copolymer self-assembly into remarkably regular and well-ordered morphologies which, depending on the molecular structure, included lamellar and cylindrical arrangements of the proton conducting ionic nanophases. Thermal analysis indicated separate glass transitions of the PFS and PPO phases, and high thermal degradation temperatures of the membranes at approximately 220 and 300 °C for the H+ and the Na+ forms, respectively. The proton conductivity of fully hydrated acidic membranes was similar to that of Nafion, reaching above 0.2 S cm−1 at 120 °C. Compared at the same ion exchange capacity, the proton conductivity of the graft copolymer membranes was two times higher than that of a membrane based on an ungrafted sulfonated PPO. The study showed that it is possible to tailor and prepare proton-exchange membranes with well-ordered morphologies and high proton conductivity by employing graft copolymers with a sulfonated backbone bearing hydrophobic side chains.

  • Head-to-head comparison of two loop-mediated isothermal amplification (LAMP) kits for diagnosis of malaria in a non-endemic setting
  • 2023
  • In: Malaria Journal. - 1475-2875. ; 22:1
  • Journal article (peer-reviewed)abstract
    • Background: Light microscopy and rapid diagnostic tests (RDT) have long been the recommended diagnostic methods for malaria. However, in recent years, loop-mediated isothermal amplification (LAMP) techniques have been shown to offer superior performance, in particular concerning low-grade parasitaemia, by delivering higher sensitivity and specificity with low laboratory capacity requirements in little more than an hour. In this study, the diagnostic performance of two LAMP kits were assessed head-to-head, compared to highly sensitive quantitative real time PCR (qPCR), in a non-endemic setting. Methods: In this retrospective validation study two LAMP kits; Alethia® Illumigene Malaria kit and HumaTurb Loopamp™ Malaria Pan Detection (PDT) kit, were evaluated head-to-head for detection of Plasmodium-DNA in 133 biobanked blood samples from suspected malaria cases at the Clinical Microbiology Laboratory of Region Skåne, Sweden to determine their diagnostic performance compared to qPCR. Results: Of the 133 samples tested, qPCR detected Plasmodium DNA in 41 samples (defined as true positives), and the two LAMP methods detected 41 and 37 of those, respectively. The results from the HumaTurb Loopamp™ Malaria PDT kit were in complete congruence with the qPCR, with a sensitivity of 100% (95% CI 91.40–100%) and specificity of 100% (95% CI 96.07–100%). The Alethia® Illumigene Malaria kit had a sensitivity of 90.24% (95% CI 76.87–97.28) and a specificity of 95.65% (95% CI 89.24–98.80) as compared to qPCR. Conclusions: This head-to-head comparison showed higher performance indicators of the HumaTurb Loopamp™ Malaria PDT kit compared to the Alethia® illumigene Malaria kit for detection of malaria.

  • 2011
  • In: Mucosal Immunology. - : Elsevier BV. - 1933-0219. ; 4, s. 438-447
  • Journal article (peer-reviewed)abstract
    • Small intestinal lamina propria (SI-LP) CD103(+) dendritic cells (DCs) are imprinted with an ability to metabolize vitamin A (retinol), a property underlying their enhanced capacity to induce the gut-homing receptors CC chemokine receptor-9 and α4β7 on responding T cells. In this study, we demonstrate that imprinting of CD103(+) DCs is itself critically dependent on vitamin A and occurs locally within the small intestine (SI). The major vitamin A metabolite retinoic acid (RA) induced retinol-metabolizing activity in DCs both in vitro and in vivo, suggesting a direct role for RA in this process. Consistent with this, SI-LP CD103(+) DCs constitutively received RA signals in vivo at significantly higher levels than did colonic CD103(+) DCs. Remarkably, SI CD103(+) DCs remained imprinted in mice depleted of dietary but not of systemic retinol. We found that bile contained high levels of retinol, induced RA receptor-dependent retinol-metabolizing activity in bone marrow-derived DCs, and imprinted these cells with the ability to generate gut-tropic T cells. Taken together, these results suggest a novel and unexpected role for bile in SI-LP CD103(+) DC imprinting.Mucosal Immunology advance online publication 2 February 2011. doi:10.1038/mi.2010.91.

  • Opportunities and barriers for implementation of Power-to-X (P2X) technologies in the West Sweden Chemicals and Materials Cluster's process industries
  • 2020
  • Reports (other academic/artistic)abstract
    • The interest for industrial electrification is currently increasing rapidly as it has been identified as one important strategy for achieving climate neutrality. This is for example illustrated by the initialization of several larger industrial cross-sectorial projects (e.g. HYBRIT, CemZero, co-operation Preem-Vattenfall) and supporting R&D-programs in Sweden and Europe during the past few years. Recently, the chemical industry in the Swedish region Västra Götaland has also shown an increasing interest for P2X, and the initiative Klimatledande processindustri (KPI) (in eng. Climate smart industry), coordinated by the West Sweden Chemicals and Materials Cluster, has identified P2X as a prioritized R&D area. The purpose of this project was to identify opportunities and barriers for the introduction of P2X technologies in the process industries of the West Sweden Chemicals and Materials Cluster, with emphasis on the chemical and refinery industry in Västra Götaland and Södra´s pulp mill in Värö, Halland. The mapping was carried out for current conditions and markets (electricity, heat) as well as future scenarios, and the results provide a basis for a regional road map for industrial electrification in the region. Another aim of the project was to identify priority areas for continued development and innovation within the framework of the KPI initiative. The analysis and the conclusions of the project are based on information collected from open literature and interviews with the participating industries and organizations. The results of the project indicate clearly that the driving forces for industrial transformation and P2X within the West Sweden Chemicals and Materials Cluster are currently variable and different depending on the industrial sector. The refineries' interest in P2X and other transformative measures, e.g. biomass and CCUS, is primarily driven by the Swedish emissions reduction obligation, while the chemical industry expresses the shift to the circular economy as the main driver for P2X. Södra, as a forest industry and net producer of electricity, can contribute significantly to this transformation by supplying electricity and excess biomass at the same time as they have their own goal “Fossil-free transport in 2030”, in which increased electrification is one of the solutions. Neither the European Emissions Trading (EU-ETS) for CO2 nor the possibility of being an active player in an increasingly flexible electricity market provide significant incentives for electrification in West Sweden process industries. There are many P2X technologies for producing different products, with widely different technology readiness levels (TRL) and suitability depending on the industrial sector. Within the cluster's oil refinery industry, there are concrete plans within the next few years for establishing P2H2 at demonstration scale. In the longer term, it is conceivable that the refinery industry will implement large-scale P2H2 concepts to satisfy a significant fraction of the hydrogen gas needs of their refinery operations (Preem), or even implement electro-fuel production, e.g. electro-methanol (Preem, St1). In addition, the SME company Liquid Wind is targeting for up to five regionally located electro-methanol plants. Borealis mainly expresses interest in various forms of P2heat, while Perstorp in the long run sees interesting opportunities in P2acids. A number of barriers have been identified for the implementation of the different P2X technologies, such as low TRL levels, high costs, uncertainties linked to integration aspects and impact on existing processes and systems, access to carbon dioxide, water and electricity at one site if electro-fuel production, etc. Other barriers raised by the industries are the lack of long-term policy and funding. However, the most significant barrier that was pointed out for large scale P2X implementation concerns uncertainty regarding the availability of fossil-free or renewable electricity capacity at competitive prices in combination with long lead times for permitting processes and expansion of the electricity grid (up to 10-12 years). The sum of the expressed power needs associated with a moderate electrification pathway (i.e. investments that are either likely to occur or that are at the planning stage) presented by the interviewed industries corresponds to a doubling of current power demand levels. A more speculative extensive electrification scenario beyond 2030 (i.e. assuming that all electrification concepts discussed during the interviews are implemented by 2045), the total power need becomes just over 10 times larger than today´s and would most likely require extensive grid reinforcements. But even with the moderate electrification plans, grid reinforcements could be needed, especially if they coincide with electrification of other sectors. This highlights the need for open and active communication between industries and power grid operators about future plans and possibilities. Finally, a number of suggestions for further work in the field have been identified, including for example development and demonstration of different advanced P2X-technologies, inventories and implementations of heat pumps, the role of P2X in relation to other pathways (based on biomass, CCS, CCU) and how to design and integrate the P2X-technologies at the overall sites, where P2X is usually only one part of the solution.

  • Can LNG be replaced with Liquid Bio-Methane (LBM) in shipping?
  • 2022
  • Reports (other academic/artistic)abstract
    • As per today (2021), in total some 500 TWh bunker fuel is consumed within the shipping sector annually within EU waters and approximately 25 TWh of this (5%) is LNG (Liquefied natural gas). The fleet of LNG fuelled vessels has grown steadily since the first vessels were introduced around year 2000. Predictions and scenarios indicate that in a couple of years, it is likely that around 15 % of all bunker fuels consumed in shipping will be LNG.Through detailed analyses of present and planned production capacity combined with scenarios built for future potential bio- and electro-methane production, a possibility to replace large amounts of LNG in shipping can be seen from a Swedish perspective.In total, the analysis shows a maximum scenario for LBM production (Liquefied Bio Methane) in Sweden year 2045 of nearly 30 TWh annually. This potential includes electro-methane production based on carbon dioxide that is naturally formed during the biogas digestion production process. All production, of methane being assessed as potential, is assessed to be based on sustainable sub¬strates and sustainably produced.This report shows that it could be possible to replace fossil LNG as a fuel in shipping with renewa¬ble LBM at a large scale from a Swedish perspective. The total bunkering of ships in Sweden are around 25 TWh per year, varies over time, and is dependant not only on which ships that calls Swe¬dish ports but also with the market competition with bunker suppliers in other countries. Should 15% of that fuel be LNG, it would be some 4 TWh LNG that could be interesting to switch towards renewable LBM.The potential shift in shipping in Sweden from LNG to LBM at a level of 4-6 TWh is assessed to be a realistic potential, but the shift will not happen unless the society gives the industry incentives that supports that shift and clearly shows the involved stakeholders that there is a long-term strat¬egy to enhance renewable methane production and consumption. It is especially important that pol¬icy instrument in the shipping sector is introduced that connects greenhouse gas emissions with a cost that can be avoided if fuels with low or zero emissions being used.Today, only a small proportion of bio-methane is liquefied to LBM in Sweden, while most of the planned production facilities for biogas will be for LBM, thanks to subsidies in the form of invest¬ment support and the decreased demand of CBG that benefits LBM.This report has chosen to use the expression Liquid Bio-Methane (LBM) due to the fact that the ex¬pression often used Liquid Bio Gas (LBG) does not cover the important part of the methane pro¬duced as an electrofuel based on carbon dioxide from the digestion process and also not really in¬cludes the methanation of syngas from gasification plants.A Swedish production support in combination with the introduction of shipping within the EU emission trading scheme (ETS) seems too possibly even out the cost difference between LNG and LBG as a marine fuel or at least give a significantly smaller barrier to overcome.To establish the environmental rationale of this product, life cycle assessments of the production of LBM and the use in the shipping sector were performed. No previous scientific studies have been identified which look into the performance of using electrofuel pathways of LBM in the shipping sector. The results are presented in the report together with an analysis of potential future issues to observe.

  • Working and living with home care - a workplace for one, a home for the other
  • 2015
  • In: [Host publication title missing].
  • Conference paper (peer-reviewed)abstract
    • As home care increases and care is moving from nursing homes and hospitals into people’s homes, there are problem areas that need to be addressed and solved in a better way than today. Nurses and other home care workers are exposed to serval risks when the patients’ home environment becomes their workplace. There are also serval risks for the patients when their homes are transferred into “small hospitals”. This paper presents the initial results from a study to identify the need for improvements in the physical environment in home care, from the perspective of both employees and patients, and to generate useful and attractive solutions. Interviews and observations were carried out, where staff members from three different healthcare teams in one municipality in Sweden were observed during their care giving shift in patients’ homes. The results indicate that care is often provided in a specific place in the home. Inadequate resources for hygiene, working surfaces or lighting result in non-ergonomic work postures, eye strain, and other risks for the practitioner and the patient. Many situations and activities are not performed in a standardized manner but open to individual differences. The interviews turned out to be the wrong approach for identifying the need for improvements, while observations through shadowing proved to be more suitable. Practitioner Summary: The amount of advanced care and technology being moved into ordinary homes is increasing. This creates the need for a physical design of the interior of the home environment which decreases the risks for both staff and patients, and creates a pleasant home environment. This study identified various objects and work situations that need improvement. Many of the homes visited lacked support for ergonomic work postures, hygienic work surfaces, adequate lighting and appropriate places to store materials.

  • Goal Model for Open Social e-Services
  • 2011
  • In: eChallenges. - : Paul Cunningham.
  • Conference paper (peer-reviewed)abstract
    • Demands on public sector to become more open and embrace new possibilities given by ICT are constantly rising. EU as well as OECD are putting high pressure on governments to improve service level for citizens and at the same time lower cost and facilitate democratic processes. The authors have gathered statements from the development of an open social e-service at a Swedish municipality and projected these onto directives regarding open government from authorities. Using goal modelling techniques a goal model for open social e-services has then been created. The model consists of four aspects that have to be taken into consideration when building open social e-services: democracy, professionalism, citizen service and administration. The model has been evaluated by research and practitioners and can facilitate the further development of open e-government in Sweden and possibly in other countries. Examples are requirement specifications for open e-services and guidance for business process modelling for the social service sector.

  • Investigation of the Sunscreen Octocrylene's Interaction with Amino Acid Analogs in the Presence of UV Radiation
  • 2012
  • In: Photochemistry and Photobiology. - : Wiley. - 0031-8655 .- 1751-1097. ; 88:4, s. 904-912
  • Journal article (peer-reviewed)abstract
    • Octocrylene is an organic UV filter, commonly used in sunscreens and cosmetics, which can give rise to both contact and photocontact allergy. Our aim was to investigate octocrylenes interaction with amino acid analogs in the presence of UV radiation to better understand the reason for octocrylenes photoallergenic capacity. The amino acid analogs were photolysed in presence and absence of octocrylene for 1 h in cyclohexane. The rate of degradation was considerably slower for all amino acid analogs when octocrylene was present in the mixture. Benzylamine, the lysine analog, did react with octocrylene during the photolysis and the corresponding amide was formed in an acylation reaction. By varying the benzylamine concentration and keeping the octocrylene concentration fixed the reaction rate was shown to be independent of the amine concentration. The same type of acylation reaction took place when octocrylene alone was photolysed in ethanol in which the ethyl ester was formed from octocrylene and ethanol. Our results suggest that octocrylenes ability to cause photocontact allergy could be due to its photoinduced reactivity toward primary amines and alcohols.

  • Ketoprofen-Induced Formation of Amino Acid Photoadducts: Possible Explanation for Photocontact Allergy to Ketoprofen
  • 2014
  • In: Chemical Research in Toxicology. - : American Chemical Society (ACS). - 0893-228X .- 1520-5010. ; 27:7, s. 1294-1303
  • Journal article (peer-reviewed)abstract
    • Photocontact allergy is a well-known side effect of topical preparations of the nonsteroidal anti-inflammatory drug ketoprofen. Photocontact allergy to ketoprofen appears to induce a large number of photocross allergies to both structurally similar and structurally unrelated compounds. Contact and photocontact allergies are explained by structural modification of skin proteins by the allergen. This complex is recognized by the immune system, which initiates an immune response. We have studied ketoprofen's interaction with amino acids to better understand ketoprofen's photoallergenic ability. Irradiation of ketoprofen and amino acid analogues resulted in four different ketoprofen photodecarboxylation products (6-9) together with a fifth photoproduct (5). Dihydroquinazoline 5 was shown to be a reaction product between the indole moiety of 3-methylindole (Trp analogue) and the primary amine benzylamine (Lys analogue). In presence of air, dihydroquinazoline 5 quickly degrades into stable quinazolinone 12. The corresponding quinazolinone (17) was formed upon irradiation of ketoprofen and the amino acids N-acetyl-L-Trp ethyl ester and L-Lys ethyl ester. The formation of these models of an immunogenic complex starts with the ketoprofen-sensitized formation of singlet oxygen, which reacts with the indole moiety of Trp. The formed intermediate subsequently reacts with the primary amino functionality of Lys, or its analogue, to form a Trp Lys adduct or a mimic thereof. The formation of a specific immunogenic complex that does not contain the allergen but that can still induce photocontact allergy would explain the large number of photocross allergies with ketoprofen. These allergens do not have to be structurally similar as long as they can generate singlet oxygen. To the best of our knowledge, there is no other suggested explanation for ketoprofen's photoallergenic properties that can account for the observed photocross allergies. The formation of a specific immunogenic complex that does not contain the allergen is a novel hypothesis in the field of contact and photocontact allergy.

  • Experimental and theoretical study of stress relaxation in high-density polyethylene
  • 2024
  • In: Acta Mechanica. - : Springer. - 0001-5970 .- 1619-6937. ; 235:4, s. 2455-2477
  • Journal article (peer-reviewed)abstract
    • Stress relaxation of high-density polyethylene is addressed both experimentally and theoretically. Two types of stress relaxation testing are carried out: uniaxial tensile testing at constant test specimen length and compression testing of a 3D structure producing inhomogeneous deformation fields and relaxation. A constitutive model for isotropic, semi-crystalline polymers is also proposed. The model has the ability to model stress relaxation at different time scales. The developed model was implemented as a user subroutine in Abaqus (UMAT). The implicit integration scheme including an algorithmic tangent modulus is described in detail. The material model is calibrated by use of the uniaxial tensile tests, and the model is then validated by simulating the compression tests of the 3D structure. The model is able to describe the uniaxial tension tests well, and the comparison between the simulations and experimental testing of the 3D structure shows very good agreement. © 2024, The Author(s).

  • Numerical and experimental analysis of inelastic and rate-dependent buckling of thin injection-moulded high-density polyethylene structure
  • 2024
  • In: International Journal of Solids and Structures. - : Elsevier. - 0020-7683 .- 1879-2146. ; 290
  • Journal article (peer-reviewed)abstract
    • Semi-crystalline polymers is an important group of materials that is used in a vast array of products. In this study, the rate-dependent properties of high-density polyethylene (HDPE) are investigated, both experimentally and theoretically. Experimental compression testing of a three-dimensional HDPE structure is performed and analysed numerically by use of the finite element method. In addition, an Eulerian constitutive material model for isotropic, semi-crystalline polymers is proposed. The model is able to account for such essential phenomena as strain-rate dependence, work hardening, pressure-dependence of inelastic deformations, and damage. The proposed material model was implemented in Abaqus as a VUMAT, which is an explicit implementation. The material model was calibrated by use of uniaxial tensile tests performed on HDPE dog-bone shaped samples, and the model was further explored by applying the VUMAT implementation to the compression tests of the HDPE structure. The simulation model was able to reproduce the experimental results well, both the uniaxial tests and the compression tests. In particular, the friction present in the compression tests seems to play an important role in determining the buckling mode of the structure.

  • Upgrading coagulation with hollow-fibre nanofiltration for improved organic matter removal during surface water treatment.
  • 2016
  • In: Water Research. - : Elsevier BV. - 1879-2448 .- 0043-1354. ; 89, s. 232-240
  • Journal article (peer-reviewed)abstract
    • Rising organic matter concentrations in surface waters in many Nordic countries require current drinking water treatment processes to be adapted. Accordingly, the use of a novel nanofiltration (NF) membrane was studied during a nine month period in pilot scale at a large drinking water treatment plant in Stockholm, Sweden. A chemically resistant hollow-fibre NF membrane was fed with full scale process water from a rapid sand filter after aluminum sulfate coagulation. The combined coagulation and NF process removed more than 90% of the incoming lake water dissolved organic carbon (DOC) (8.7 mg C L(-1)), and 96% of the absorbance at 254 nm (A254) (0.28 cm(-1) incoming absorbance). Including granulated active carbon GAC) filter, the complete pilot plant treatment process we observed decreases in DOC concentration (8.7-0.5 mg C L(-1)), SUVA (3.1-1.7 mg(-1) L m(-1)), and the average nominal molecular mass (670-440 Da). Meanwhile, water hardness was practically unaffected (<20% reduction). Humic substances (HS) and biopolymers were almost completely eliminated (6510-140 and 260 to 10 μg C L(-1) respectively) and low molecular weight (LMW) neutrals decreased substantially (880-190 μg C L(-1)). Differential excitation emission matrices (EEMs), which illustrate the removal of fluorescing organic matter (FDOM) over a range of excitation and emission wavelengths, demonstrate that coagulation removed 35 ± 2% of protein-like material and 65 ± 2% of longer emission wavelength, humic-like FDOM. The subsequent NF treatment was somewhat less selective but still preferentially targeted humic-like FDOM (83 ± 1%) to a larger extent than protein-like material (66 ± 3%). The high selectivity of organic matter during coagulation compared to NF separation was confirmed from analyses with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS), and liquid chromatography with organic carbon detection (LC-OCD), as coagulation exclusively targeted oxidized organic matter components while NF removed both chemically reduced and oxidized components. DOC removal and change in DOC character in the GAC filters showed marked differences with slower saturation and more pronounced shifts in DOC character using NF as pre-treatment. Fluorescence derived parameters showed a similar decrease over time of GAC performance for the first 150 days but also indicated ongoing change of DOM character in the post NF GAC filtrate over time even after LC-OCD indicated steady state with respect to outgoing carbon. During our trial iron concentrations were low (<30 ppb) and thus A254 could be directly related to the concentration of HS (R(2) = 0.9). The fluorescence derived freshness index (β:α) proved to be an excellent variable for estimating the fraction of HS present in all samples. Given the recommended limit of 4 mg L(-1) for chemical oxygen demand (COD) for Swedish drinking water, coagulation will need to be supplemented with one or more treatment steps irrespective whether climate change will lead to drier or wetter conditions in order to maintain sufficient DOC removal with the current increasing concentrations in raw waters.
