    Estimating winter survival of winter wheat by simulations of plant frost tolerance2018In: Journal of Agronomy and Crop Science, ISSN 0931-2250, E-ISSN 1439-037X, Vol. 204, no 1, p. 62-73Article in journal (Refereed)
    Abstract [en]

    Based on soil temperature, snow depth and the grown cultivar's maximum attainable level of frost tolerance (LT50c), the FROSTOL model simulates development of frost tolerance (LT50) and winter damage, thereby enabling risk calculations for winter wheat survival. To explore the accuracy of this model, four winter wheat cultivars were sown in a field experiment in Uppsala, Sweden in 2013 and 2014. The LT50 was determined by tests of frost tolerance in November, and the cultivars’ LT50c was estimated. Further, recorded winter survival from 20 winter wheat field variety trials in Sweden and Norway was collected from two winter seasons with substantial winter damages. FROSTOL simulations were run for selected cultivars at each location. According to percentage of winter damage, the cultivar survival was classified as “survived,” “intermediate” or “killed.” Mean correspondence between recorded and simulated class of winter survival was 75% and 37% for the locations in Sweden and Norway, respectively. Stress factors that were not accounted for in FROSTOL might explain the poorer accuracy at the Norwegian locations. The accuracy was poorest for cultivars with intermediate LT50c levels. When low temperature was the main cause of damage, as at the Swedish locations, the model accuracy was satisfying.

    Fibrinogen Adsorption and Conformational Change on Model Polymers: Novel Aspects of Mutual Molecular Rearrangement2009In: Langmuir, ISSN 0743-7463, E-ISSN 1520-5827, Vol. 25, no 10, p. 5602-5608Article in journal (Refereed)
    Abstract [en]

    By combining quartz crystal microbalance with dissipation monitoring (QCM-D) and surface plasmon resonance (SPR), the organic mass, water content, and corresponding protein film structure of fibrinogen adsorbed to acrylic polymeric substrates with varying polymer chain flexibility was investigated. Albumin and immunoglobulin G were included as reference proteins. For fibrinogen, the QCM-D model resulted in decreased adsorbed mass with increased polymer chain flexibility. This stands in contrast to the SPR model, in which the adsorbed mass increased with increased polymer chain flexibility. As the QCM-D model includes the hydrodynamically coupled water, we propose that on the nonflexible polymer significant protein conformational change with water incorporation in the protein film takes place. Fibrinogen maintained a more native conformation on the flexible polymer, probably due to polymer chain rearrangement rather than protein conformational change. In comparison with immunoglobulin G and albumin, polymer chain flexibility had only minor impact on adsorbed mass and protein structure. Understanding the adsorption and corresponding conformational change of a protein together with the mutual rearrangement of the polymer chain upon adsorption not only has implications in biomaterial science but could also increase the efficacy of molecular imprinted polymers (MIPs).

    Gold-nanoparticle-assisted self-assembly of chemical gradients with tunable sub-50 nm molecular domains2014In: Particle & particle systems characterization, ISSN 0934-0866, E-ISSN 1521-4117, Vol. 31, no 2, p. 209-218Article in journal (Refereed)
    Abstract [en]

    A simple and efficient principle for nanopatterning with wide applicability in the sub-50 nanometer regime is chemisorption of nanoparticles; at homogeneous substrates, particles carrying surface charge may spontaneously self-organize due to the electrostatic repulsion between adjacent particles. Guided by this principle, a method is presented to design, self-assemble, and chemically functionalize gradient nanopatterns where the size of molecular domains can be tuned to match the level corresponding to single protein binding events. To modulate the binding of negatively charged gold nanoparticles both locally (<100 nm) and globally (>100 μm) onto a single modified gold substrate, ion diffusion is used to achieve spatial control of the particles' mutual electrostatic interactions. By subsequent tailoring of different molecules to surface-immobilized particles and the void areas surrounding them, nanopatterns are obtained with variable chemical domains along the gradient surface. Fimbriated Escherichia coli bacteria are bound to gradient nanopatterns with similar molecular composition and macroscopic contact angle, but different sizes of nanoscopic presentation of adhesive (hydrophobic) and repellent poly(ethylene) glycol (PEG) domains. It is shown that small hydrophobic domains, similar in size to the diameter of the bacterial fimbriae, supported firmly attached bacteria resembling catch-bond binding, whereas a high number of loosely adhered bacteria are observed on larger hydrophobic domains. Chemical gradients with the resolution needed to address complex biological binding events at the single protein level are prepared using surface-deposited gold nanoparticles as a versatile template for orthogonal chemicalmodifications. The effect of hydrophobic domain arrangement on the sub-50 nm scale is shown to influence binding of fimbriae carrying E. coli bacteria.

    Experiences from feeding and co-firing of lignin powder in a lime kiln2010In: International Chemical Recovery Conference, 2010, Vol. 1, p. 175-187Conference paper (Refereed)
    Abstract [en]

    A significant part of the fossil fuel oil consumption at a pulp mill today is related to combustion in the lime kiln. Therefore, replacing fuel oil with lignin in this application has been one of the most important issues in the FRAM2 (Future Resource-Adapted Mill) research program coordinated by Innventia (formerly STFl-Packforsk) and funded by Sodra and other partners. A full-scale trial to fire lignin powder in a lime kiln was carried out at the Sodra Cell Monsteras mill, as part of the research program. In total 37 tonnes of lignin was co-fired with fuel oil. For part of the trial the kiln was operated on 100 % lignin. The experiences from the trial imply that it is possible to achieve stable and continuous operation of a lime kiln when lignin is used as the main fuel. The temperature levels in the kiln are of the same order of magnitude as when firing fuel oil or wood powder. Sulfur capture by the lime is very efficient, but there is a threshold above which S02 emissions increase rapidly. In the trial this step change occurred when going from 90 % to 100 % lignin firing. Based on the trial results, it is possible to produce lime with consistent quality when firing lignin, and the temperature reached in the burner zone is sufficient for proper sintering of the lime nodules. White liquor can be produced from the lime with the same causticizing efficiency and at the same rate as during normal operation. The mill operators also commented that it was easier to control the performance of the kiln when co-firing lignin and oil compared to the normal operation with co-firing of bark and oil.

    Pilot-scale combustion studies with kraft lignin as a solid biofuel2008In: Engineering, Pulping and Environmental Conference 2008, TAPPI Press, 2008, Vol. 4, p. 2571-2580Conference paper (Refereed)
    Abstract [en]

    Processing of kraft lignin precipitated from black liquor to produce a solid biofuel with high energy density and low ash content has been developed in research programs by STFI-Packforsk and partners. In preparation for full-scale combustion trials, tests were carried out on pilot scale in a 150 kW powder burner and in a 12 MWfluidized bed (CFB) boiler. Lignin powder could be fired in a powder burner with good combustion performance after some trimming of the airflows to reduce swirl. Lignin dried to 10 % moisture content was easy to feed smoothly and had less bridging tendencies in the feeding system than wood/bark powder. In the CFB boiler lignin was easily handled and co-fired together with bark. Although the filter cake was broken into smaller pieces and fines the combustion was not disturbed. When co-firing lignin with bark, the sulfur emission increased compared to bark firing only, but most of the sulfur was captured by calcium in the bark ash. Conventional sulfur capture with addition of limestone to the bed was also demonstrated. The sulfur content in the lignin had a significantly positive effect on reducing the alkali chloride content in the deposits, thus reducing the high temperature corrosion risk.

    Pilot-scale combustion studies with kraft lignin in a powder burner and a CFB boiler2010In: TAPPI Journal, ISSN 0734-1415, Vol. 9, no 6, p. 24-30Article in journal (Refereed)
    Abstract [en]

    Processes have been developed to produce a solid biofuel with high energy density and low ash content from kraft lignin precipitated from black liquor. Pilot-scale tests of the lignin biofuel were carried out with a 150 kW powder burner and a 12 MW circulating fluidized bed (CFB) boiler. Lignin powder could be fired in a powder burner with good combustion performance after some trimming of the air flows to reduce swirl. Lignin dried to 10% moisture content was easy to feed smoothly and had less bridging tendencies in the feeding system than did wood/ bark powder. In the CFB boiler, lignin was easily handled and cofired together with bark. Although the filter cake was broken into smaller pieces and fines, the combustion was not disturbed. When cof ¡ring lignin with bark, the sulfur emission increased compared with bark firing only, but most of the sulfur was captured by calcium in the bark ash. Conventional sulfur capture also occurred with addition of limestone to the bed. The sulfur content in the lignin had a significantly positive effect on reducing the alkali chloride content in the deposits, thus reducing the high temperature corrosion risk. Application: This research is of interest for pulp and paper and energy and utilities companies that want to understand how kraft lignin can be used to replace fuel oil or coal in many combustion applications.

    A method for visualization of surface texture anisotropy in different scales of observation2011In: Scanning, ISSN 0161-0457, E-ISSN 1932-8745, Vol. 33, no 5, p. 325-331Article in journal (Refereed)
    Abstract [en]

    Anisotropy of functional surfaces can in many practical cases significantly influence the surface function. Tribological contacts in sheet forming and engine applications are good examples. This article introduces and exemplifies a method for visualization of anisotropy. In a single graph, surface texture properties related to the anisotropy as a function of scale are plotted. The anisotropy graph can be used to explain anisotropy properties of a studied surface such as texture direction and texture strength at different scales of observation. Examples of milled steel surfaces and a textured steel sheet surface are presented to support the proposed methodology. Different aspects of the studied surfaces could clearly be seen at different scales. Future steps to improve filtering techniques and an introduction of length-scale analysis are discussed.

    Industrial needs and available techniques for geometry assurance for metal AM parts with small scale features and rough surfaces2018In: Procedia CIRP, Elsevier B.V. , 2018, p. 131-136Conference paper (Refereed)
    Abstract [en]

    From an industrial perspective this paper aims to explore the state of the art regarding GD&T for metal additive manufacturing, specifically regarding product definition and inspection. The available techniques for geometry assurance for parts with small scale features and rough surfaces are evaluated in terms of suitability for the task and readiness for industrial implementation. It is found that many of the remaining challenges seem to be related to processing of data rather than obtaining data. Current difficulties are related to issues such as calibration, surface determination and defining the most relevant parameters to tolerance and inspect.

    Abstract [en]

    The effect of nitrocarburizing were investigated for two different steels, 42CrMo4 and 25CrMo4, with objective to evaluate the influence of initial surface topography on the resulting nitrocarburized surface with regard to surface topography and thickness of the compound layer. It was found that the nitrocarburizing process has an impact on the surface topography. The process creates a short-wave isotropic structure on the original surface and this is particularly evident for the smoother original surfaces. No significant effect on the compound layer thickness depending on the surface topography before heat treatment could be observed. © Published under licence by IOP Publishing Ltd.

    New ways of organizing product introductions2012In: Work, 2012, Vol. 41, no SUPPL.1, p. 4856-4861Conference paper (Refereed)
    Abstract [en]

    The aim of this paper is to describe and reflect on an interactive research approach used to address the challenges on how to improve product introductions, the part of the product realization process associated with the transfer of a product from product development to serial production. In the interactive research approach, research results as well as improvement of practice are given equal importance. The collaboration between researchers and practitioners therefore addresses both the focus and the process of the change. The approach includes four main iterative steps: 1) mapping/diagnosis, 2) feedback of results, 3) participation in development activities, and 4) follow-up/evaluation. The paper reports findings from interactive research in one company within office product industry and one company group, consisting of three company units within the engine industry. Preliminary findings indicate that the participating companies afterwards work in a more structured way with product introductions and that the employees have gained deeper knowledge about product introductions as well as experienced the advantages of working across functional boundaries. Furthermore, the interactive research approach is suitable to run projects from an ergonomics perspective as it focuses on developing both practice and theory, it is human-centered, and it emphasizes broad participation from practitioners. © 2012 - IOS Press and the authors.

    Boundary crossing in product introductions considering humans, technology and organization2014In: Proceedings of ODAM NES 2014 / [ed] O. Broberg, N. Fallentin, P. Hasle, P.L. Jensen, A. Kabel, M.E. Larsen, T. Weller, 2014, p. 349-354Conference paper (Refereed)
    Abstract [en]

    The objective of the paper is to analyze how a product introduction involving Swedish-Chinese collaboration was influenced by human, technological and organizational aspects. The study showed that technical challenges concerned the infrastructure for communication and quality issues; organizational challenges concerned the new project model and updating drawing versions; and human related challenges included cultural differences and communication. The product introduction was highly challenging by crossing earlier boundaries in the human, technical, and organizational subsystems. Strong work demands were placed on the individuals while offering great opportunities for individual learning. Concurrent development of a new project model resulted in organizational learning.

    INTERACTIVE RESEARCH INPRODUCTION START-UP2018Conference paper (Refereed)
    Abstract [en]

    Research regarding production start-ups hasincreased in interest during the last decades.However, there is still a need to learn more aboutsuitable research approaches in production startupsas the research need to be carried out in achallenging environment, where industrialpractitioners often have time-pressure, handlingevents and uncertainties related to both the productand the production system. This paper is based ona meta-analysis of four research projectsaddressing production start-ups including activitiesbefore, during and after the start-ups. Focus of thepaper is on how an interactive research approachcan be implemented to achieve learning andchange among individual practitioners, at grouplevel and at organizational level. The findings ofthe paper may contribute to increasedunderstanding of interactive research in dynamicprocesses and contribute to the development ofresearch on production start-ups.

    Det värdefulla engagemanget: En guide för Lean och för andra strategier för utveckling2011Book (Other academic)
    Abstract [sv]

    En organisation där alla agerar på eget initiativ för det gemensamma bästa, där alla är beredda att hugga i när det behövs, där alla samspelar för att nå resultat och där alla bidrar till att utveckla organisationen-visst är detta en dröm?Alla vill att medarbetarna och kollegorna ska engagera sig. Men varför skulle de? Har företaget gjort sig förtjänt av att någon gör mer än hon måste?I de allra flesta organisationer underskattas gravt den omsorg som behövs för att medarbetarna ska finna det mödan värt att engagera sig. Det krävs ett klokt och långsiktigt arbete från ledning och chefer för att bygga en företagskultur av förtroende och samverkan, men om det lyckas finns oanade vinster att hämta.Den nya boken, Det värdefulla engagemanget-En guide för Lean och andra strategier för utveckling, vill stimulera till en reflektion kring hur organisationen och ledningen påverkar medarbetarnas engagemang. Boken följer upp vår tidigare bok Lean i ledningen-Utmana hela organisationen, som blivit mycket uppskattad, men Det värdefulla engagemanget är till nytta oberoende av eventuella Leansatsningar.Tio teman behandlas: En färdriktning • En kultur av tillit • Aktiv ledning • Långsiktighet • Utrymme för individen • Lagarbete • Inflytande • Utmaning • Lärande • Del av vinstenDe kunskaper och erfarenheter som lett fram till boken har sin grund i många års uppdrag och forskningsprojekt inom industrin och även i tjänsteföretag. Boken bygger till stor del på en doktorsavhandling,Engagemang efterfrågas – Hur tre tillverkande företag söker medverkan från sina medarbetare när de inför Lean, men är förenklad och omskriven för att direkt kunna tillämpas.

    Towards goal-based autonomic networking2009In: Proceedings of the Distributed Autonomous Network Magagement Systems Workshop (DANMS 2008), November 2008, 2009, 1, , p. 5Conference paper (Refereed)
    Abstract [en]

    The ability to quickly deploy and efficiently manage services is critical to the telecommunications industry. Currently, services are designed and managed by different teams with expertise over a wide range of concerns, from high-level business to low level network aspects. Not only is this approach expensive in terms of time and resources, but it also has problems to scale up to new outsourcing and/or multi-vendor models, where subsystems and teams belong to different organizations. We endorse the idea, upheld among others in the autonomic computing community, that the network and system components involved in the provision of a service must be crafted to facilitate their management. Furthermore, they should help bridge the gap between network and business concerns. In this paper, we sketch an approach based on early work on the hierarchical organization of autonomic entities that possibly belong to different organizations. An autonomic entity governs over other autonomic entities by defining their goals. Thus, it is up to each autonomic entity to decide its line of actions in order to fulfill its goals, and the governing entity needs not know about the internals of its subordinates. We illustrate the approach with a simple but still rich example of a telecom service.

    Achievable Accuracy in Industrial Measurement of Dissipation Factor of Power Capacitors2018In: NCSLI Measure, ISSN 1931-5775, Vol. 12, no 1, p. 34-41Article in journal (Refereed)
    Abstract [en]

    Modern dielectrics used in power capacitors can exhibit a dissipation factor lower than 0.005 %, which approaches the limits of presently available measurement techniques. This article reviews techniques, apparatus, and available calibration services for dissipation factor with regard to lowest achievable uncertainties. It is shown that further metrological advances are necessary to lower uncertainty in the measurement to levels at least five times less than presently achievable, in order to ensure traceable and quality-assured measurement of modern dielectrics with such low dissipation factors

    Estimation of errors of voltage transformers on-site and the uncertainty of the estimate2000In: CPEM Digest (Conference on Precision Electromagnetic Measurements), 2000, p. 415-416Conference paper (Refereed)
    Abstract [en]

    A deregulated energy market needs demonstrably correct energy measurements for correct billing. Voltage transformers may be prone to drift implying a need for verification of their errors. A method to do this on-site using previous calibrations and comparative measurements has been developed and its uncertainty has been estimated.

    Influence of coaxial cable on response of high-voltage resisitive dividers2017Conference paper (Refereed)
    Abstract [en]

    An effort is pursued by several European National Measurement Institutes to lower the uncertainties in calibration of UHV measuring systems for lightning impulse. To this end, several reference dividers are investigated as regards their accuracy both for amplitude and for time parameters. During these investigations a deterioration of step response was identified when longer coaxial cables were inserted in the measuring circuit. The measured front time T1 was also affected, in one observed case by 2.5 % elongation of front time as another 25 m cable was inserted. Compared to the intention to calibrate front time measurement to better than 5 % uncertainty for front time, this contribution must be well known, or preferably be eliminated. This paper presents the experimental findings from these investigations. The investigated cables included selected coaxial, tri-axial, and cables with a corrugated screen. The effect of cable length was also studied. The influence was first discovered when applying a very fast step (rise-time < 4 ns) to the high voltage arm of a resistive divider and convolution of this step with the time derivative of an ideal lightning impulse with 0.84/60 µs impulse. The calculated output was analysed with IEC 61083 compliant software to evaluate the front time. Subsequently, these analyses have been augmented by additional comparative measurements where two reference dividers were connected to the same impulse generator, and varying the cable length of one of them. The summarized changes in front time calculated for different combinations of cable and impulse voltage dividers are shown and discussed. It is noted that a change in T1 error depends both on length of cable and its type. The results show that non-negligible front time errors may be introduced when the cable length is increased. To support these findings, further tests have been carried out with two reference impulse dividers connected in standard calibration configuration in accordance with IEC 60060-2. One divider was used as reference, while the cable for the other was varied. In this way, the change of error between configurations could be measured. A theoretical study has also been performed, calculating the distortion of a lightning impulse on a coaxial cable. The results agree qualitatively with experiments, but the detailed results show discrepancies that need further investigation.
