In: European Planning Studies. - : Informa UK Limited. - 0965-4313 .- 1469-5944. ; 26:1, s. 35-54

Journal article (peer-reviewed)abstract
- Spatial planning using a landscape approach has been recognized as being essential for reconciling ecological, cultural and socioeconomic dimensions in sustainable development (SuD). Although embraced as a concept, there is a lack of planning tools capable of incorporating multi-level, multifunctional and multi-sectoral perspectives, especially in a rural context. The departure point in this paper is the legal requirements for municipal comprehensive planning (MCP) in Sweden and an e-mail survey about incentives, stakeholder involvement, policy integration and implementation in MCP in all 15 Swedish mountain municipalities. The purpose of this explorative study is to examine whether MCP could be a tool in planning for SuD. Results indicate a general lack of resources and a low status of MCP that affect, and even limit, stakeholder involvement, policy integration and implementation. However, legal requirements for MCP are targeted at SuD, and municipal personnel responsible for planning appreciate the potential of MCP. Therefore, there is potential to develop the MCP into an effective landscape planning tool. To accomplish this, the status of an active planning process has to be raised, the mandate of the local planning agency has to be secured, and residents and land users have to be involved throughout the planning process.

A struggling collaborative process : revisiting the woodland key habitat concept in Swedish forests
- 2019

In: Scandinavian Journal of Forest Research. - : Taylor & Francis Group. - 0282-7581 .- 1651-1891. ; 34:8, s. 699-708

Journal article (peer-reviewed)abstract
- The term woodland key habitat (WKH) was launched in Sweden in 1990. Definitions for the concept have changed over the years, and today the WKH concept and its application are issues of debate in Sweden. Consequently, the Swedish Forestry Agency (SFA) initiated a collaborative process including forest stakeholders with the purpose to clarify the application and develop the inventory methodology of WKH. We have studied, by means of interviews and observations, participant perceptions of how endogenous and exogenous factors affect the collaborative process. During our research, we identified three game changers: the pause in WKH registration in northwestern Sweden that caused several participants to drop out of the process; budget allocations for new nationwide WKH inventories that put the process on hold; and formal instructions from the government that came nine months later and essentially re-initiated the collaborative process. Altogether, this not only affected the participants’ abilities, understanding and willingness to participate, but also the overall legitimacy of the process – indicating the difficulty of conducting policy development in collaborative form, especially when it is highly politicized since it impact on the participants’ anticipation of the process and its end results.

Quantifying differences in hepatic uptake of the liver specific contrast agents Gd-EOB-DTPA and Gd-BOPTA : a pilot study
- 2012
-
In: European Radiology. - : Springer Berlin/Heidelberg. - 0938-7994 .- 1432-1084. ; 22:3, s. 642-653
-
Journal article (peer-reviewed)abstract
- Objectives To develop and evaluate a procedure for quantifying the hepatocyte-specific uptake of Gd-BOPTA and Gd-EOB-DTPA using dynamic contrast-enhanced (DCE) MRI. Methods Ten healthy volunteers were prospectively recruited and 21 patients with suspected hepatobiliary disease were retrospectively evaluated. All subjects were examined with DCE-MRI using 0.025 mmol/kg of Gd-EOB-DTPA. The healthy volunteers underwent an additional examination using 0.05 mmol/kg of Gd-BOPTA. The signal intensities (SI) of liver and spleen parenchyma were obtained from unenhanced and enhanced acquisitions. Using pharmacokinetic models of the liver and spleen, and an SI rescaling procedure, a hepatic uptake rate, K Hep, estimate was derived. The K Hep values for Gd-EOB-DTPA were then studied in relation to those for Gd-BOPTA and to a clinical classification of the patient’s hepatobiliary dysfunction. Results K Hep estimated using Gd-EOB-DTPA showed a significant Pearson correlation with K Hep estimated using Gd-BOPTA (r = 0.64; P < 0.05) in healthy subjects. Patients with impaired hepatobiliary function had significantly lower K Hep than patients with normal hepatobiliary function (K Hep = 0.09 ± 0.05 min-1 versus K Hep = 0.24 ± 0.10 min−1; P < 0.01). Conclusions A new procedure for quantifying the hepatocyte-specific uptake of T 1-enhancing contrast agent was demonstrated and used to show that impaired hepatobiliary function severely influences the hepatic uptake of Gd-EOB-DTPA. Key Points • The liver uptake of contrast agents may be measured with standard clinical MRI. • Calculation of liver contrast agent uptake is improved by considering splenic uptake. • Liver function affects the uptake of the liver-specific contrast agent Gd-EOB-DTPA. • Hepatic uptake of two contrast agents (Gd-EOB-DTPA, Gd-BOPTA) is correlated in healthy individuals. • This method can be useful for determining liver function, e.g. before hepatic surgery

INNOTRACK Deliverable 4.2.1 -- Simplified relation for the influence of rail/joint degradation on operational loads and subsequent deterioration
- 2007
-
Reports (other academic/artistic)abstract
- In this tentative report we present a summary of the work carried out during approximately the first nine months of the INNOTRACK project regarding the influence of rail/joint degradation on operational loads and subsequent deterioration. The focus is here on the vertical train–track interaction and related deterioration.The work within this field can be divided in two categories. The first concerns the collection of input and validation data. In this category the current deliverable includes measurements of in-field axle loads, in-field monitoring of squats and compilation of material data.The second category is the actual numerical simulation and resulting quantifications of increased operational loads and deteriorations. Here the deliverable includes a state-of-the-art study of the effect of material characteristics on material deterioration and the practical implications. Further, the deliverable contains reports of parametric studies of the influence of rail corrugation, the growth of larger rail cracks, the influence of the design of insulated joints and the influence of rail squats.

INNOTRACK Deliverable 4.2.3 -- Improved model for loading and subsequent deterioration of insulated joints
- 2009
-
Reports (other academic/artistic)abstract
- Numerical simulations have been carried out to assess the influence of key parameters on the deterioration of insulated joints. The measures of fatigue damage were adopted; one low-cycle fatigue based and one ratcheting based. Both of these models are based on the stress–strain evolution, which consequently needs to be accurately modelled. This calls for a constitutive model that can deal with plasticity under general multi- axial loading. In the current study the material parameters in the constitutive model have been calibrated to reflect the characteristics of the rail steel grade 900A.The simulations verify previous findings that the insulating layer does not carry any significant load. Consequently severe strains occur at the rail head edge. The ratcheting based fatigue criterion was found to be the most suitable for the current study and the accumulated plastic strain after four load passages, εeff, was adopted to quantify the ratcheting. The numerical simulations showed that increasing the insulating gap from 4 mm to 6 mm gives roughly the same effect as an increase of the vertical load from 150 kN to 200 kN, which is an increase in εeff of about 10%. In addition, a very detrimental effect of traction and braking was found: Increasing the longitudinal load from 0 kN up to 45 kN caused an increase in εeff magnitudes with up to 95%.The predictions of plastic deformation and rolling contact fatigue have been performed. A fixed traction coefficient was presumed giving a wear pattern that is a linear function of pressure, which is in turn proportional to the cube-root of the applied normal force. The highest wear is predicted immediately after the insulated joint, with additional high-wear spots appearing a few metres later as the wheel bounces down and settles.In addition to numerical simulations four operational joints have been monitored in field to follow the degradation. It was found that material damage is induced very fast. In accordance to numerical simulations the rail ends closest to a nearby station showed the largest degree of damage. This damage had a wear-like appearance. After 8 months it was found that also “cavity-like” damages had formed in the vicinity of the insulating joint.

Supply or demand? : Institutionalization of the mentally ill in the emerging Swedish welfare state, 1900–1959
- 2021
-
Reports (other academic/artistic)abstract
- Historical studies on the institutionalization of the mentally ill have primarily relied on data on institutionalized patients rather than the population at risk. Consequently, the underlying factors of institutionalization are unclear. Using Swedish longitudinal microdata from 1900–1959 reporting mental disorders, we examine whether supply-side factors such as distance to institutions and number of asylum beds influenced the risk of institutionalization, in addition to demand-side factors such as access to family. Institutionalization risks were associated with the supply of beds and proximity to an asylum, but also dependent on families’ unmet demand for care of relatives. As the supply of mental care met this family-driven demand in the 1930s, the relative risk of institutionalization increased among those lacking family networks.

Journal article (peer-reviewed)abstract
- Numerical simulations are performed to study plastic deformation and fatigue impact of an insulated joint. The simulations feature a sophisticated constitutive model capable of capturing ratcheting under multi-axial loading conditions. Calculation results are presented in the form of effective strain magnitudes, plastic zone sizes, and multi-axial low cycle fatigue parameters. The simulation results indicate that the main damage mechanism at insulated joints is ratcheting and not low cycle fatigue.A parametric study quantifies effects of increased vertical and longitudinal load magnitudes,as well as the effect of an increased insulating gap. In particular, longitudinal loading is indicated as being severely deteriorating for the rail in the vicinity of the joint. Finally, the effect of rail edge bevelling is assessed and found to be small for the case studied.

Analysis of rail breaks and insulated joint deterioration
- 2008
-
Licentiate thesis (other academic/artistic)abstract
- The thesis deals with fatigue related issues in the field of railway mechanics. In particular rail breaks and deterioration of insulating joints are investigated. The study is largely motivated by plans to increase allowed axle loads in Sweden. The aim is to deliver operational results, as well as exemplify how practical problems in railway mechanics can be assessed by computer based simulations.In the first appended paper the influence of wheel flat impacts on the growth of rail cracks and subsequent rail breaks is analyzed. This calls for an analysis of the dynamic train--track interaction combined with a fracture mechanics analysis of crack growth and fracture. To account for high frequency excitations due to wheel flat impacts the in-house code DIFF is employed for the analysis of train--track interaction. Stress intensity factors for rail cracks are derived using FE-simulations. Added loading due to restricted thermal contraction of all-welded rails is included. Risks of rail breaks for specified crack sizes and temperatures are evaluated as functions of impact load magnitudes. In addition crack growth rates are quantified. Simulation results indicate that wheel flats increase the risk of rail breaks, but have a limited influence on rack growth rates. The latter is due to the infrequent occurrence of wheel flats and the fact that these need to impact in a rather narrow region to cause any considerable influence on the crack growth rate.In the second paper deterioration of insulated joints is analyzed by 3D FE-simulations. Repeated negotiations of a loaded wheel over an insulating joint is simulated. To obtain realistic material responses, an advanced constitutive model is employed. The simulations indicate the accumulated strain (ratcheting) to be the dominant damage mechanism. In a parametric study the influence of insulating gap, axel load, frictional force, and coefficient of maximum friction in the wheel--rail interface is assessed. In particular the frictional force (traction/braking) is found to have a major influence on joint deterioration. A limited field study has been carried out and provided some qualitative confirmation of the simulations.

Conference paper (peer-reviewed)abstract
- Four operational joints at the Swedish West Coast Line have been monitored in field from installation and during three years of operation to follow degradation. Even though operational loads were comparatively low, material damage was found to occur early after installation. All joints showed a similar damage pattern with dominating deformation on the side towards a nearby station. In addition some joints showed “cavity-like” damage on the off-station side. The paper reports observations on continuing degradation of the joints as well as hardness evolution and increased joint dip over time.

Journal article (peer-reviewed)abstract
- The equivalent Dang Van stress under Hertzian contacts is evaluated over the subsurface space using four computational approaches. The accuracy and computational efficiency of the different models is assessed. It is found that an approach consisting in finding the minimum circumscribed hypersphere to the deviatoric stress path in time gives a good trade-off between accuracy and efficiency. It is also shown that a very computationally cheap approximation employing half the peak Tresca shear stress results in good agreements in the entire subsurface space for conditions relevant under wheelrail contacts.

In: Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit. - 0954-4097 .- 2041-3017. ; 223:2, s. 153-161
-
Journal article (peer-reviewed)abstract
- The risk for rail breaks is investigated from mechanical and statistical points of view with particular focus on the influence of impact loads from flatted wheels. For a presumed rail head crack geometry and rail temperature, the stochastic relation between the crack position along the rail and the wheel flat impact position results in a risk of fracture. In addition to the analysis of the risk for final fracture, rail crack growth is also studied. Inparticular, the contribution of wheel flat impacts on crack growth rates is quantified.The study takes the form of a dynamic load analysis that evaluates rail bending moments due to wheel flat impact. Then, a fracture mechanics analysis is employed to establish stress intensity factors for rail head cracks under bending and temperature loading. These analyses are then combined to give risks of rail breaks and to quantify crack growth rates for varying operational conditions.

Conference paper (peer-reviewed)abstract
- Subsurface initiated rolling contact fatigue cracks initiate in the vicinity of material defects. As these exist randomly in the material, fatigue will appear randomly under otherwise constant conditions. By combining statistical methods with a contact mechanics and fatigue analysis, probabilities of fatigue initiation are evaluated. The developed model takes as input contact geometry, contact load and the statistical properties of the material defects. It is shown that under some well-defined presumptions the probability of rolling contact fatigue initiation in a rolling wheel can be expressed by a simple formula. Based on this, the parametric influence is assessed and it is found that the mean material defect size has a large influence. The benefit of material cleanliness testing procedures and the influence of the allowed defect size on the risk of subsurface initiated rolling contact fatigue in railway wheels are then quantified with the aid of numerical simulations.

Subsurface rolling contact fatigue damage of railway wheels – A probabilistic analysis
- 2012
-
In: International Journal of Fatigue. - : Elsevier BV. - 0142-1123. ; 37, s. 146-152
-
Journal article (peer-reviewed)abstract
- A numerical model for predicting the probability of subsurface initiated rolling contact fatigue failure in railway wheels subjected to operational loading is presented. The loading is evaluated through simulations of dynamic train–track interaction incorporating the influence of, e.g., corrugation. Contact stresses are found from Hertzian theory and the resulting stress field from theory of elasticity. Fatigue damage is evaluated by use of a Wöhler curve where the fatigue strength is decreased due to the influence of material defects, which are presumed to be of random size and occurrence in the stressed volume of the wheel rim. Damage accumulation is performed using the Palmgren–Miner rule, extending the model to cases of variable loading.The results show how a combination of rail corrugation and high train speeds have a significant impact on the probability of fatigue failure. A sensitivity analysis reveals a strong influence of the fatigue strength and the material defect distribution on the probability of fatigue failure.

Wheels, Rails and Insulated Joints - Damage and Failure Probability at High Speed and Axle Load
- 2011
-
Doctoral thesis (other academic/artistic)abstract
- The thesis deals with some fatigue related problems in railway mechanics related to increased axle loads and speeds. The focus is on defects and discontinuities in the wheel--rail system that affect the risk of fatigue and fracture of railway components such as wheels, rails and insulated joints.Numerical simulations are performed to study plastic deformation and fatigue impact on an insulated joint. The simulations feature a sophisticated constitutive model able to model multi-axial ratchetting which is indicated as the main damage mechanism. Effects are quantified for increased vertical and longitudinal load magnitudes and insulating gap width. High longitudinal loading is found to be severely deteriorating for the rail material. The risk for rail breaks is investigated from mechanical and statistical points of view with focus on impacts of flatted wheels. The influence of wheel flat impacts on rail cracks is quantified from a dynamic load analysis that evaluates rail bending moments. Stress intensity factors for rail head cracks under bending and temperature loading are then evaluated. A stochastic relation is established between the crack and the wheel flat impact positions. Finally rail crack growth and fracture are predicted using standard methods. To evaluate the risk of subsurface cracking in a wheel, the Dang Van equivalent stress under Hertzian contacts is evaluated. Two methods for this evaluation are found to be useful when considering accuracy and efficiency. Subsurface initiated rolling contact fatigue cracks initiate in the vicinity of material defects. As these exist randomly in the material, fatigue will appear randomly under otherwise constant conditions. Further, corrugation of the rail adds to the randomness. A combination of statistical methods, contact mechanics and fatigue analysis is employed for the analysis. Statistical properties of the material defects, contact geometry and contact load or the output from a full train--track simulation are taken as input. For the failure analysis, the damage accumulation for random amplitude loading is evaluated. The results show how a combination of rail corrugation and high train speeds has a significant impact on the probability of fatigue. A sensitivity analysis reveals a strong influence of the fatigue strength and the material defect distribution.

Journal article (peer-reviewed)abstract
- Patients with obesity are prescribed more opioids than the general population.To compare opioid consumption in patients with obesity who underwent Roux-en-Y bariatric surgery (RYGB) with population controls with and without obesity, not undergoing bariatric surgery, and to identify characteristics associated with opioid use.This study included all patients with a principal diagnosis of obesity, aged 18-72 years, with a RYGB surgical code in the Swedish Patient Register between 2007 and2013.RYGB patients (n = 23,898) were age- and sex-matched with 1 control patient with obesity (n = 23,898) and 2 population controls without obesity (n = 46,064). Participants were classified as nonconsumers and consumers based on their opioid dispensations during the 12 months before baseline. Opioid consumption was assessed for 24 months.Nonconsumers. Within 24 months, a significantly higher proportion of RYGB patients (16.6%) started using opioids compared with the controls with obesity (14.3%, P < .0001) and population controls (5.4%, P < .0001). RYGB patients and controls with obesity had higher median dailyintake of opioid morphine equivalent (MEQ) (2.8 mg/d) than population controls (2.5 mg/d, P < .0001). Consumers. Within 24 months, the proportion of RYGB patients and controls with obesity that was using opioids were similar (53.1% and 53.4%), but higher compared to population controls (38.0%, P < .0001). The median daily opioid MEQ was higher among RYGB patients than in population controls (10.5 versus 7.8 mg/d, P < .0001). RYGB patients, overall, had higher incidence of bowel surgery and cholecystectomy compared with controls with obesity and population controls, leading to prolonged opioid use in this group. Opioid consumption in general was associated with chronic pain and psychiatric disorder, which were more common in patients with obesity than in the population controls.RYGB surgery increased the risk of prolonged opioid use in patients with obesity who were nonconsumers before surgery but had no effect on overall opioid use among prior consumers. RYGB-associated complications requiring surgery influenced opioid use for both nonconsumers and consumers. Regular reassessments of pain mechanisms and specific treatment owing to type of paincould prevent unnecessary opioid use in this patient group.

Technological development for sustainability : The role of network management in the innovation policy mix
- 2019

In: Technological forecasting & social change. - : Elsevier. - 0040-1625 .- 1873-5509. ; 138, s. 309-323

Journal article (peer-reviewed)abstract
- Despite the key role of actor networks in progressing new sustainable technologies, there is a shortage of conceptual knowledge on how policy can help strengthen collaborative practices in such networks. The objective of this paper is to analyze the roles of such policies – so-called network management – throughout the entire technological development processes. The analysis draws on the public management and sustainability transitions literatures, and discusses how various network characteristics could affect the development of sustainable technologies, including how different categories of network management strategies could be deployed to influence actor collaborations. The paper's main contribution is an analytical framework that addresses the changing roles of network management at the interface between various phases of the technological development process, illustrated with the empirical case of advanced biorefinery technology development in Sweden. Furthermore, the analysis also addresses some challenges that policy makers are likely to encounter when pursuing network management strategies, and identifies a number of negative consequences of ignoring such instruments in the innovation policy mix. The latter include inefficient actor role-taking, the emergence of small, ineffective and competing actor networks in similar technological fields, and a shortage of interpretative knowledge.
