    Influence of Glycosylation on Interfacial Properties of Recombinant Mucins: Adsorption, Surface Forces, and Friction2017Inngår i: Langmuir, ISSN 0743-7463, E-ISSN 1520-5827, Vol. 33, nr 18, s. 4386-4395Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Interfacial properties of two brush-with-anchor mucins, C-P55 and C-PSLex, have been investigated at the aqueous solution/poly(methyl methacrylate) (PMMA) interface. Both are recombinant mucin-type fusion proteins, produced by fusing the glycosylated mucin part of P-selectin glycoprotein ligand-1 (PSLG-1) to the Fc part of a mouse immunoglobulin in two different cells. They are mainly expressed as dimers upon production. Analysis of the O-glycans shows that the C-PSLex mucin has the longer and more branched side chains, but C-P55 has slightly higher sialic acid content. The adsorption of the mucins to PMMA surfaces was studied by quartz crystal microbalance with dissipation. The sensed mass, including the adsorbed mucin and water trapped in the layer, was found to be similar for these two mucin layers. Atomic force microscopy with colloidal probe was employed to study surface and friction forces between mucin-coated PMMA surfaces. Purely repulsive forces of steric origin were observed between mucin layers on compression, whereas a small adhesion was detected between both mucin layers on decompression. This was attributed to chain entanglement. The friction force between C-PSLex-coated PMMA is lower than that between C-P55-coated PMMA at low loads, but vice versa at high loads. We discuss our results in terms of the differences in the glycosylation composition of these two mucins.

    Effect of solvent quality and chain density on normal and frictional forces between electrostatically anchored thermoresponsive diblock copolymer layers2017Inngår i: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 487, s. 88-96Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Equilibration in adsorbing polymer systems can be very slow, leading to different physical properties at a given condition depending on the pathway that was used to reach this state. Here we explore this phenomenon using a diblock copolymer consisting of a cationic anchor block and a thermoresponsive block of poly(2-isopropyl-2-oxazoline), PIPOZ. We find that at a given temperature different polymer chain densities at the silica surface are achieved depending on the previous temperature history. We explore how this affects surface and friction forces between such layers using the atomic force microscope colloidal probe technique. The surface forces are purely repulsive at temperatures <40 °C. A local force minimum at short separation develops at 40 °C and a strong attraction due to capillary condensation of a polymer-rich phase is observed close to the bulk phase separation temperature. The friction forces decrease in the cooling stage due to rehydration of the PIPOZ chain. A consequence of the adsorption hysteresis is that the friction forces measured at 25 °C are significantly lower after exposure to a temperature of 40 °C than prior to heating, which is due to higher polymer chain density on the surface after heating.

    Tethered Poly(2-isopropyl-2-oxazoline) Chains: Temperature Effects on Layer Structure and Interactions Probed by AFM Experiments and Modeling2015Inngår i: Langmuir, ISSN 0743-7463, E-ISSN 1520-5827, Vol. 31, nr 10, s. 3039-3048Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Thermoresponsive polymer layers on silica surfaces have been obtained by utilizing electrostatically driven adsorption of a cationic–nonionic diblock copolymer. The cationic block provides strong anchoring to the surface for the nonionic block of poly(2-isopropyl-2-oxazoline), referred to as PIPOZ. The PIPOZ chain interacts favorably with water at low temperatures, but above 46 °C aqueous solutions of PIPOZ phase separate as water becomes a poor solvent for the polymer. We explore how a change in solvent condition affects interactions between such adsorbed layers and report temperature effects on both normal forces and friction forces. To gain further insight, we utilize self-consistent lattice mean-field theory to follow how changes in temperature affect the polymer segment density distributions and to calculate surface force curves. We find that with worsening of the solvent condition an attraction develops between the adsorbed PIPOZ layers, and this observation is in good agreement with predictions of the mean-field theory. The modeling also demonstrates that the segment density profile and the degree of chain interpenetration under a given load between two PIPOZ-coated surfaces rise significantly with increasing temperature.

    Uncertainties in façade fire tests - Measurements and modeling2016Inngår i: MATEC Web of Conferences, 2016, artikkel-id 03002Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper a comparison between test and modelling results are performed for two large-scale façade fire testing methods, namely SP Fire 105 and BS 8414-1. In order to be able to compare tests and modelling the uncertainties have to be quantified both in the test and the modelling. Here we present a methodology based on deterministic sampling to quantify uncertainties in the modelling input. We find, in general good agreement between the models and the test results. Moreover, temperatures estimated by plate thermometers is indicated to be less sensitive to small variations in model input and is thus suitable for these kind of comparisons.

    Applying uncertainty quantification in modelling of a steel beam exposed to fire2016Inngår i: Structures in Fire: Proceedings of the Ninth International Conference, 2016, s. 925-932Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Modelling of structures exposed to fires is prone to be heavily influenced by uncertainties in geometrical parameters, thermal material data as well as uncertainties in the boundary conditions. Assessing the effects and influences in variations of all the uncertain parameters is often cumbersome and traditional methods are impractical thus modelling of the total uncertainty is needed. Uncertainty Quantification with deterministic sampling is one possible way ahead to accommodate and evaluating the effects of uncertainties with as few repeated simulations as possible. In this paper the uncertainties stemming from error in the input data and boundary conditions on one example of a steel beam under four point bending exposed to fire is evaluated.

    Apparent interfacial shear strength of short-flax-fiber/starch acetate composites2016Inngår i: International Journal of Adhesion and Adhesives, ISSN 0143-7496, E-ISSN 1879-0127, Vol. 64, s. 78-85Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The paper deals with an indirect industry-friendly method for identification of the interfacial shear strength (IFSS) in a fully bio-based composite. The IFSS of flax fiber/starch acetate is evaluated by a modified Bowyer and Bader method based on an analysis of the stress-strain curve of a short-fiber-reinforced composite in tension. A shear lag model is developed for the tensile stress-strain response of short-fiber-reinforced composites allowing for an elastic-perfectly plastic stress transfer. Composites with different fiber volume fractions and a variable content of plasticizer have been analyzed. The apparent IFSS of flax/starch acetate is within the range of 5.5-20.5 MPa, depending on composition of the material. The IFSS is found to be greater for composites with a higher fiber loading and to decrease with increasing content of plasticizer. The IFSS is equal or greater than the yield strength of the neat polymer, suggesting good adhesion, as expected for the chemically compatible constituents.

    Capacity Study of Statistical Multiplexing for IP Telephony2000Rapport (Annet vitenskapelig)
    Abstract [en]

    Transmitting telephone calls over the Internet causes problems not present in current telephone technology such as packet loss and delay due to queueing in routers. In this undergraduate thesis we study how a Markov modulated Poisson process is applied as an arrival process to a multiplexer and we study the performance in terms of loss probability. The input consists of the superposition of independent voice sources. The predictions of the model is compared with results obtained with simulations of the multiplexer made with a network simulator. The buffer occupancy distribution is also studied and we see how this distribution changes as the load increases.

    Dosin - A new Pump Device. Its Construction and Function.2007Inngår i: Uppsala Journal of Medical Science, Vol. 112, nr 1, s. 83-93Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    ABSTRACT The research and development of the Dosin® and the medical injection system in which it is used was initiated in response to a demand for a new and improved method of delivering fluids to patients. The key requirement was to make the use of refillable syringes obsolete in a cost- effective and user-friendly alternative. Most syringes, despite their accurate delivery quotas, have a limited volume that necessitates frequent monitoring and filling or changing. This very act is time consuming and potentially dangerous in inexperienced hands. The new principle of the device makes it capable of delivering (medical) fluids of various consistencies in extremely precise amounts regardless of the fluid viscosity. The outlet of the Dosin® goes through another innovation, the bubble detector, which detects any change in direction of a light beam that passes through the content of the outlet. Thus, should an air bubble enter the outflow and hence be about to enter the blood stream of a patient, the flow of fluid will halt immediately and an alarm will notify the user of the problem.The cyclic flow is useful in interventional radiology since it prevents clotting and increases the mixing with the blood. The flow rate varies from 0.03 mL/s to 5 mL/s and it is recommended to use fluid with a viscosity lower than 3 mPa.s. The outlet pressure is recommended below 300 mm Hg. The Dosin® must be replaced after each patient, alternatively after maximum 24h continuous use.

    Abstract [en]

    In an earlier paper (1) a new pump device for medical applications was described. This enabled a continuous flow of saline, barium contrast agent and gases. We now report further study of this device: The use of gases was experimentally studied to give a basis for use in CT-colonography. We also report experiences from injection of barium contrast agent via a naso-duodenal tube for radiological investigation of the small intestine in patients with gastrointestinal suffering. The radiation exposure to the x-ray staff was reduced. The investigation procedure was standardised and shortened.

    SAGA -- Syntax Analyzer Generator for Agents1995Rapport (Annet vitenskapelig)
    Abstract [en]

    LALR(1) parser generators in conjunction with imperative programming languages is the standard solution for parsing applications. Contrary to popular belief, this situation is not entirely satisfactory. With imperative tools like Yacc, it is difficult to add actions to a grammar without introducing conflicts. Also, LALR(1) is not powerful enough to meet the needs of languages like C++. We argue that LALR(1) parsing in conjuction with concurrent constraint programming is an interesting option that solves the former problem. We also show how deep guards and don't-know non-determinism can be exploited to solve the latter problem. These ideas have been incorporated in the Saga parser generator described in this report. Saga is an integrated generator for lexical analyzers and parsers. It is based on AKL, a multiparadigm programming language based on a concurrent constraint framework. It is intended both as a research tool to demonstrate the power offered by concurrent constraints, and as a practical tool for the Agents programming system. As a practical tool, Saga features many improvements over tools like Yacc. For example, Saga offers powerful syntax, elegant reporting and resolution of conflicts and powerful error handling in the generated syntax analyzers.

    Camera-based Colour Contrast Evaluation2012Rapport (Fagfellevurdert)
    Abstract [en]

    This project studies whether or not a digital camera can be used to evaluate colour difference or colour contrast. When characterizing a test object that changes colour over time it is not always possible to do a normal colour measurement with a spectroradiometer. The alternative could be to use film or rapid fire photography to record the changes and extract the colour data from the digital information. This project involves development of a method where spectroradiometric data of a colour chart is compared to digital data taken from photos and film of the same colour chart using Photoshop. In each measurement 22 colours have been evaluated by calculating the colour difference between a direct spectroradiometric measurement of a single colour and data taken from Photoshop of that same colour. The data is compared in the CIELAB colour space using the ?E94 metric which should faithfully represent how the human eye perceives colour difference. Three sets of measurements are made .Two sets where the spectroradiometric data is compared to data from still photos, first with photos directly from the camera and then with RAW-data from the camera. The third measurement compared the spectroradiometric data with data from a frame from a video. The results show that the 22 colours are reproduced with varying degrees of accuracy in photos and video compared to a direct measurement using a spectroradiometer. For the two photo measurements the results span from ?E94 = 0.82 for the best colour reproduction to ?E94 = 17.01 for the worst reproduction. The average deviation was ?E94 = 7.48 and ?E94 = 8.46 respectively where a colour difference of ?E94 =1.0 is considered a just noticeable difference. For video the deviation spans from ?E94 = 4.89 to ?E94 = 18.11 with an average deviation of ?E94 = 11.59. ?E94 has also been used to evaluate how the colour contrast between two different colours differ between the spectroradiometric measurement and data from Photoshop. The results show that for photos the colour contrast deviates quite a bit between the two methods. A deeper evaluation of the video method shows that as long as the contrast between two colours is small the deviation compared to the spectroradiometric measurement will also be small.

    A holistic and experimentally-based view on recycling of off-gas dust within the integrated steel plant2018Inngår i: Metals, ISSN 2075-4701, Vol. 8, nr 10, artikkel-id 760Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Ore-based ironmaking generates a variety of residues, including slags and fines such as dust and sludges. Recycling of these residues within the integrated steel plant or in other applications is essential from a raw-material efficiency perspective. The main recycling route of off-gas dust is to the blast furnace (BF) via sinter, cold-bonded briquettes and tuyere injection. However, solely relying on the BF for recycling implicates that certain residues cannot be recycled in order to avoid build-up of unwanted elements, such as zinc. By introducing a holistic view on recycling where recycling via other process routes, such as the desulfurization (deS) station and the basic oxygen furnace (BOF), landfilling can be avoided. In the present study, process integration analyses were utilized to determine the most efficient recycling routes for off-gas dust that are currently not recycled within the integrated steel plants of Sweden. The feasibility of recycling was studied in experiments conducted in laboratory, pilot, and full-scale trials in the BF, deS station, and BOF. The process integration analyses suggested that recycling to the BF should be maximized before considering the deS station and BOF. The experiments indicated that the amount of residue that are not recycled could be minimized.

    Upgrading of Blast Furnace Sludge and Recycling of the Low-Zinc Fraction via Cold-bonded Briquettes2019Inngår i: Journal of Sustainable Metallurgy, ISSN 2199-3823, Vol. 5, nr 3, s. 350-361Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Depending on the operation of the blast furnace (BF), the main outlet of zinc from the furnace is more or less via the BF dust and sludge. As the dust is recycled to the BF, the sludge has to be de-zinced prior to recycling to prevent the accumulation of zinc in the BF. De-zincing and recycling of the low-zinc fraction via sinter have been reported. However, no research concerning recycling of upgraded BF sludge via cold-bonded briquettes has been performed. In the present study, a fine-grained BF sludge with low zinc content, generated by a BF operating on a ferrous burden of 100% pellets, was upgraded using the tornado process. The process simultaneously dried and separated the BF sludge into a high-zinc and a low-zinc fraction. The feasibility of recycling the low-zinc fraction to the BF using cold-bonded briquettes was studied on a laboratory-scale BF shaft simulator. On comparison with a reference briquette, the experiments indicated that 10 wt% of the upgraded BF sludge can be added to the briquette without negatively affecting the reducibility. Higher additions were found to render the briquette less reduced compared to the reference under test conditions corresponding to the central part of the BF. The strength of the briquettes was not compromised with the addition of the upgraded BF sludge, and a decision to study the briquettes in the LKAB experimental blast furnace was made in order to evaluate the behavior under actual BF conditions.

    Calibration of Gain Ratios on nV-Meters with the Reference Step Method2018Inngår i: CPEM 2018 - Conference on Precision Electromagnetic Measurements, 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The Reference Step Method for calibrators can be modified for calibration also of the gain ratios on a meter. The method has earlier been evaluated in the range 100 mV-1000 V on DMM HP 3458A1 and shows that an accuracy of typically &lt; ± 0.2 μ V/V could be obtained. We have investigated the performance of the method when calibrating ratios in the range 1 mV-100 mV on two common nV-meters. In our comparisons with the Josephson Voltage Standard the differences are within ± ± 12μ V/V at the ratio 10m V:1mV and within ± ± 1.3μ V/V at 100mV:10mV.

    Fuktsäkring av krypgrunder1991Rapport (Annet vitenskapelig)
    Abstract [sv]

    Hur fuktsäkrar man moderna uteluftventilerade krypgrunder med träbjälklag? Jo, genom värmeisolering på marken eller på blindbottnens undersida mot kryprummet alternativt genom ventilation kombinerad med uppvärmning eller avfuktning i kryprummet. Avsikten med de gjorda teoretiska studierna och fältstudierna är att utveckla fuktsäkrare uteluftventilerade krypgrunder med trä och träbaserade material i bottenbjälklaget samt att finna sätt att förstärka en krypgrunds fuktskydd och därmed dess motståndsförmåga mot biologiska angrepp.
