    Experimental and Numerical Characterization of an Electrically Propelled Vehicles Battery Casing Including Battery Module2014Inngår i: Journal of Thermal Science and Engineering Applications, Vol. 6, nr 4, s. 41015-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper demonstrates the possibility to predict a battery system's performance in a fire resistance test according to the new amendment of United Nations Regulation No. 100 "Uniform Provisions Concerning the Approval of Vehicles with Regard to Specific Requirements for the Electric Power Train" (R100) based on careful measurements of the physical properties of the casing material, as well as modeling of the battery modules and computer simulations. The methodology of the work consists of estimating the heat transfer coefficients by using a gasoline pool fire model in the computational fluid dynamics (CFD) software FIRE DYNAMICS SIMULATOR (FDS), followed by finite-element (FE) calculations of the temperatures in the battery.

    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.

    Gastrointestinal Radiological Investigations with a New Pump Device: Experimental and Clinical Experiences2008Inngår i: Ups J Med Sci., Vol. 113, nr 1, s. 73-8Artikkel i tidsskrift (Annet vitenskapelig)
    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.

    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.

    The adhesion of Bacillus cereus spores to epithelial cells might be an additional virulence mechanism1998Inngår i: International Journal of Food Microbiology, ISSN 0168-1605, E-ISSN 1879-3460, Vol. 39, nr 42006, s. 93-99Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Four out of ten Bacillus cereus strains produced spores able to adhere to monolayers of Caco-2 cells (human epithelial cells). One of these strains has been involved in an outbreak of food poisoning where the symptoms were more severe and persisted for longer than a normal B. cereus food poisoning. The hydrophobicity of the spores is a contributing factor for the adhesion to occur. The spores are able to germinate in an environment similar to that of the small intestine and then the vegetative cells can produce the enterotoxin directly at the target place. A concentrated and active form of the enterotoxin will be taken up by the epithelial cells in the small intestine. Spore adhesion could be an important virulence factor for some B. cereus strains.

    Adhesion and removal of dormant, heat-activated, and germinated spores of three strains of Bacillus cereus1998Inngår i: Biofouling (Print), ISSN 0892-7014, E-ISSN 1029-2454, Vol. 13, nr 1, s. 51-67Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    As the spores of Bacillus cereus are known to be very adhesive, the cleaning processes used to eliminate them are often inefficient. This study investigated how adhesion and removal of spores varied among strains of the species B. cereus. The adhesion and removal of spores during their life cycle were also examined. Spores of three different strains of B. cereus, viz. NVH 61, 1AM 1110 and NCTC 2599, were used. IAM 1110 spores adhered in greater numbers than spores of the other two strains and were the most hydrophobic; four times as many spores of this strain adhered than of the least adhesive spores, NCTC 2599. Spores of both these strains have an exosporium and appendages, but as the relative hydrophobicity varies, there are probably differences in their chemical composition. It was also found that dormant spores were 33-48% more adhesive than germinated spores. There were no obvious differences in adhesion between dormant and heat-activated spores. Up to 80% of the germinated spores could be removed from the surfaces tested. Dormant and heat-activated spores on the other hand were difficult to remove from the surfaces. When siliconized glass surfaces were coated with milk, germinated spores were still the easiest to remove but the difference was not as marked as before. Therefore, this work suggests that cleaning processes should take into consideration factors that boost spore germination in order to improve the cleaning.

    Abstract [en]

    Spore-forming Bacillus cereus and Clostridium perfringens bacteria are special problems for the dairy and meat industry, respectively. Proper cleaning and disinfection with hypochlorite is essential to avoid high numbers of these bacteria in food products. It is impossible for B. cereus and C. perfringens to cause food poisoning with cooking and rapid cooling, and proper reheating. It is also important to note that the generation time for C. perfringens can be as short as 8 min under optimal conditions, so temperatures between 10 and 47 °C in any meat product must be restricted. B. cereus food poisoning through milk and milk products can be avoided with a low number of spores in the products and proper cooling.

    Comparison between automatic ribotyping and random amplified polymorphic DNA analysis of Bacillus cereus isolates from the dairy industry1999Inngår i: International Journal of Food Microbiology, ISSN 0168-1605, E-ISSN 1879-3460, Vol. 47, nr 42006, s. 147-151Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Discrimination by automatic ribotyping and random amplified polymorphic DNA PCR, RAPD, was compared for 40 different B. cereus dairy isolates, 4 different B. mycoides isolates and 6 culture collection strains. RAPD-PCR has previously shown to be useful for tracing contamination routes of B. cereus to milk. Automatic ribotyping using EcoRI and PvuII separated the B. cereus and B. mycoides isolates/strains into 36 different ribotypes. RAPD-typing with primers generated 40 different RAPD-profiles. However, 17 isolates clustered into eight groups, irrespective of the primer and restriction enzyme used, and in all but one case, the isolates with the same pattern were isolated from the same dairy. Automatic ribotyping proved to be a useful, standardized and quick method to discriminate between B. cereus strains, only slightly less discriminatory than RAPD-typing.

    Discrimination by automatic ribotyping and random amplified polymorphic DNA PCR, RAPD, was compared for 40 different B. cereus dairy isolates, 4 different B. mycoides isolates and 6 culture collection strains. RAPD-PCR has previously shown to be useful for tracing contamination routes of B. cereus to milk. Automatic ribotyping using EcoRI and PvuII separated the B. cereus and B. mycoides isolates/strains into 36 different ribotypes. RAPD-typing with primer 1 (5?-CCGAGTCCA-3?) and primer 2 (5?-CCGGCGGCG-3?) generated 40 different RAPD-profiles. However, 17 isolates clustered into 8 groups, irrespective of the primer and restriction enzyme used and in all but one case, the isolates with the same pattern were isolated from the same dairy. To conclude RAPD-typing was only slightly more discriminatory than automatic ribotyping and therefore automatic ribotyping proved to be a useful, standardized and quick method to discriminate between B. cereus strains. As the two methods are based on completely different genetic properties, one of the methods can be used to confirm the results from the other method, when identity among isolates needs to be verified.

    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.

    Selection of building materials for healthy buildings with special reference to wood products1994Rapport (Annet vitenskapelig)
    Abstract [sv]

    Materialvalsprocessen i samband med projektering och byggande har förändrats så att andra egenskaper hos byggnadsmaterialen än de rent tekniska har fått ökad tyngd. Förändringen, som fortfarande pågår, innebär framför allt att en större uppmärksamhet ges åt materialens miljöpåverkan, både gällande yttre miljö och inomhusmiljö. Intresset ökar för materialens eventuella inverkan på människors hälsa, och speciellt för deras avgivning till luften av flyktiga organiska ämnen.

    Barrier properties and heat sealability/failure mechanisms of dispersion coated paperboard2002Inngår i: Packaging technology & science, ISSN 0894-3214, E-ISSN 1099-1522, Vol. 15, s. 209-224Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Plate-like fillers are often added to improve barrier properties and to prevent blocking of dispersion coatings on paper and board. We have studied the effects of clay addition, neutralizing agent and drying conditions on water vapour permeability, water absorption, oxygen permeability and heat sealability of carboxylated styrene/butyl acrylate dispersion coatings on a pilot scale. The barrier dispersions were applied on a pre-coated side of a three-ply board, using a pre-metering roll coater. Coated strips were sealed under specified conditions of temperature, time and pressure and the sealability was assessed by measuring the peak load necessary to break the joints. The surface composition of the barrier-coated board was analysed and the mode of failure was characterized by ESCA. The occurrence of pinholes in the barrier coatings was assessed by both staining tests and ESEM/EDX analysis of the surface topography. The resulting barrier properties were satisfactory as far as resistance to water transport in both liquid and vapour form is concerned. The oxygen permeability was similar to that of similar amorphous polymers. Heat-sealing tests showed that the mode of failure was mainly cohesive in nature, as fibre tear occurred when sealed strips were separated. Neutralization with sodium hydroxide gave poor adhesion and had a negative effect on the seal strength. Barrier measurements and ESEM/EDX analysis both showed that the pinholes present extended only through the barrier coating

    Preparation and incorporation of microcapsules in functional coatings for self-healing of packaging board2009Inngår i: Packaging technology & science, ISSN 0894-3214, E-ISSN 1099-1522, Vol. 22, nr 5, s. 275-291Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The replacement of flexible polyolefin barrier layers with novel, thin, functional polymer coatings in the production of paperboard packaging involves the risk of deteriorated barrier and mechanical properties during the converting process. Local defects or cracks in the protective barrier layer can arise because of the stress induced in creasing and folding operations. In this study, the incorporation of microencapsulated self-healing agents in coating formulations applied both by spot- and uniform-coating techniques was studied. The preparation process of microcapsules with a hydrophobic core surrounded by a hydrophobically modified polysaccharide membrane in aqueous suspension was developed to obtain capsules fulfilling both the criteria of small capsule size and reasonably high solids content to match the requirements set on surface treatment of paperboard for enhancement of packaging functionality. The survival of the microcapsules during application and their effectiveness as self-healing agents were investigated. The results showed a reduced tendency for deteriorated barrier properties and local termination of cracks formed upon creasing. The self-healing mechanism involves the rupture of microcapsules local to the applied stress, with subsequent release of the core material. Crack propagation is hindered by plasticization of the underlying coating layer, while the increased hydrophobicity helps to maintain the barrier properties.

    Effects of molecular weight on permeability and microstructure of mixed ethyl-hydroxypropyl-cellulose films2013Inngår i: European Journal of Pharmaceutical Sciences, ISSN 0928-0987, E-ISSN 1879-0720, Vol. 48, nr 42006, s. 240-248Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Films of ethyl cellulose (EC) and water-soluble hydroxypropyl cellulose (HPC) can be used for extended release coatings in oral formulations. The permeability and microstructure of free EC/HPC films with 30% w/w HPC were studied to investigate effects of EC molecular weight. Phase separation during film spraying and subsequent HPC leaching after immersion in aqueous media cause pore formation in such films. It was found that sprayed films were porous throughout the bulk of the films after water immersion. The molecular weight affected HPC leaching, pore morphology and film permeability; increasing the molecular weight resulted in decreasing permeability. A model to distinguish the major factors contributing to diffusion retardation in porous films showed that the trend in permeability was determined predominantly by factors associated with the geometry and arrangement of pores, independent of the diffusing species. The film with the highest molecular weight did, however, show an additional contribution from pore wall/permeant interactions. In addition, rapid drying and increasing molecular weight resulted in smaller pores, which suggest that phase separation kinetics affects the final microstructure of EC/HPC films. Thus, the molecular weight influences the microstructural features of pores, which are crucial for mass transport in EC/HPC films. © 2012 Elsevier B.V. All rights reserved.
