    Printed electrochemical instruments for biosensors2015In: ECS Transactions, 2015, Vol. 66, no 37, p. 1-13Conference paper (Refereed)
    Abstract [en]

    Mobile diagnostics for healthcare, food safety and environmental monitoring, demand a new generation of inexpensive sensing systems suitable for production in high volume. Herein we report on the development of a new disposable electrochemical instrument exploiting the latest advances in printed electronics and printed biosensors. The current system is manufactured under ambient conditions with all interconnections printed; electrochemical measurements and data elaboration are realized by the integration onto the platform of two chips: a MICROCHIP-PIC24F16KA101 and a Texas Instrument's LMP91000. A PEDOT.PSS vertical electrochromic display (VECD) is also incorporated into the system to visualize the data. A printed Enfucell 3V manganese dioxide battery was used to deliver the required power. Finally, in order to demonstrate the utility of the system, screen-printed sensors for the detection of glucose were added and the performance of the overall system was evaluated.

    Protective effects of the angiotensin II AT2 receptor agonist compound 21 in ischemic stroke: a nose-to-brain delivery approach.2018In: Clinical Science, ISSN 0143-5221, E-ISSN 1470-8736, Vol. 132, no 5, p. 581-593Article in journal (Refereed)
    Abstract [en]

    Significant neuroprotective effects of angiotensin II type 2 (AT2) receptor (AT2 receptor) agonists in ischemic stroke have been previously demonstrated in multiple studies. However, the routes of agonist application used in these pre-clinical studies, direct intracerebroventricular (ICV) and systemic administration, are unsuitable for translation into humans; in the latter case because AT2 receptor agonists are blood-brain barrier (BBB) impermeable. To circumvent this problem, in the current study we utilized the nose-to-brain (N2B) route of administration to bypass the BBB and deliver the selective AT2 receptor agonist Compound 21 (C21) to naïve rats or rats that had undergone endothelin 1 (ET-1)-induced ischemic stroke. The results obtained from the present study indicated that C21 applied N2B entered the cerebral cortex and striatum within 30 min in amounts that are therapeutically relevant (8.4-9 nM), regardless of whether BBB was intact or disintegrated. C21 was first applied N2B at 1.5 h after stroke indeed provided neuroprotection, as evidenced by a highly significant, 57% reduction in cerebral infarct size and significant improvements in Bederson and Garcia neurological scores. N2B-administered C21 did not affect blood pressure or heart rate. Thus, these data provide proof-of-principle for the idea that N2B application of an AT2 receptor agonist can exert neuroprotective actions when administered following ischemic stroke. Since N2B delivery of other agents has been shown to be effective in certain human central nervous system diseases, the N2B application of AT2 receptor agonists may become a viable mode of delivering these neuroprotective agents for human ischemic stroke patients

    Impact of physical activity and cardiovascular fitness on total homocysteine concentrations in European adolescents: The HELENA study2015In: Journal of Nutritional Science and Vitaminology, ISSN 0301-4800, E-ISSN 1881-7742, Vol. 61, no 1, p. 45-54Article in journal (Refereed)
    Abstract [en]

    We examined the association of physical activity (PA), cardiovascular fitness (CVF) and fatness with total homocysteine (tHcy) concentrations in European adolescents. The present study comprised 713 European adolescents aged 14.8±1.2 y (females 55.3%) from the multicenter HELENA cross-sectional study. PA was assessed through accelerometry, CVF by the 20-m shuttle run test, and body fat by skinfold thicknesses with the Slaughter equation. Plasma folate, cobalamin, and tHcy concentrations were measured. To examine the association of tHcy with PA, CVF, and fatness after controlling for a set of confounders including age, maturity, folate, cobalamin, creatinine, smoking, supplement use, and methylenetetrahydrofolate reductase 677 genotype (CC 47%, CT 43%, TT 10%), bivariate correlations followed by multiple regression models were performed. In the bivariate correlation analysis, tHcy concentrations were slightly negatively correlated (p<0.0 5) with CVF in females (measured both by stages: r=-0.118 and by VO 2 max: r=-0.10 2) and positively with body mass index (r=0.10 0). However, daily time spent with moderate and vigorous PA showed a weak positive association with tHcy in females (p<0.0 5). tHcy concentrations showed a tendency to decrease with increasing CVF and increase with increasing BMI in female European adolescents. However, tHcy concentrations were positively associated with moderate and vigorous PA in female European adolescents.

    Spaces of Interaction2010Conference paper (Refereed)
    Abstract [en]

    As the world becomes increasingly computationally enabled, so our view of human-computer interaction (HCI) needs to evolve. The proliferation of wireless connectivity and mobile devices in all their various forms moves people from being outside a computer and interacting with it to being inside an information space and moving through it. Sensors on the body, wearable computers, wireless sensor networks, increasingly believable virtual characters and speech-based systems are all contributing to new interactive environments. New forms of interaction such as gesture and touch are rapidly emerging and interactions involving emotion and a real sense of presence are beginning. These are the new spaces of interaction we need to understand, design and engineer. Most importantly these new forms of interaction are fundamentally embodied. Older views of a disembodied cognition need to be replaced with an understanding of how people with bodies live in and move through spaces of interaction.

    Spreading joy: examining the effects of smiling models on consumer joy and attitudes2015In: Journal of Consumer Marketing, ISSN 0736-3761, E-ISSN 2052-1200, Vol. 32, no 6, p. 459-469Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to examine consumer response to pictures of smiling models in marketing, focusing on the roles of emotional contagion from the smiling models and the perceived typicality of marketing with smiling models. Design/methodology/approach – This paper reports the findings from three experimental studies, comparing consumer response to two versions of an advertisement (Study 1) and a packaging design (Study 2 and 3), including either a picture of a smiling or a non-smiling model. To measure consumer response, a combination of self-report questionnaires and eye-tracking methodology was used. Findings – The pictures of smiling models produced more consumer joy and more positive attitudes for the marketing. The positive effects on attitudes were mediated by consumer joy, and the effects on consumer joy were mediated by the perceived typicality of the marketing with smiling models. Originality/value – Despite the ubiquity of photos of smiling faces in marketing, very few studies have isolated the effects of the smile appeal on consumer response to marketing objects. By comparing marketing where the same model is shown smiling or with a neutral facial expression, the positive effects were isolated. The roles of emotional contagion and perceived typicality in this mechanism were also examined and implications of the findings for research and practitioners are discussed.

    Perspectives on environmental and cost assessment of lithium metal negative electrodes in electric vehicle traction batteries2019In: Journal of Power Sources, ISSN 0378-7753, E-ISSN 1873-2755, Vol. 415, p. 83-90Article in journal (Refereed)
    Abstract [en]

    Using a lithium metal negative electrode may give lithium metal batteries (LMBs), higher specific energy density and an environmentally more benign chemistry than Li-ion batteries (LIBs). This study asses the environmental and cost impacts of in silico designed LMBs compared to existing LIB designs in a vehicle perspective. The life cycle climate and cost impacts of LMBs show a similar pattern: the use phase has more climate and cost impacts than the production phase. As compared to LIBs and with respect to the positive electrode, Lithium Nickel Manganese Cobalt Oxide (NMC) is preferable to Lithium Iron Phosphate (LFP). The cell cost is highly dependent on the cost of lithium metal; a cost reduction of 50% causes a cell cost reduction of 8–22% depending on the choice of positive electrode material and if the cell is optimised for power or energy. For electric vehicle usage, the total cost per km is mainly dependent on the energy consumption per km and the capacity of the positive electrode, representing cost saving potentials of about 10%. These generic results can be used as a base for investigations of other battery technology using lithium metal electrodes.

    Crater formation in Langmuir-Blodgett films induced by electronic sputtering with fast heavy ions1987In: Applied Physics Letters, ISSN 0003-6951, E-ISSN 1077-3118, Vol. 51, no 17, p. 1379-Article in journal (Refereed)
    Abstract [en]

    Secondary ion formation by fast heavy ion impact (electronic sputtering) on Langmuir–Blodgett films of fatty acids has been studied. The results show unambiguously that molecular ions originate from molecules in layers other than the surface layer. Furthermore, the results indicate that craters may be formed in electronic sputtering of such films. The depth of the craters depends on the stopping power of the incident ion and lower limits of the order of 100–200 Å are obtained from the ion data.

    The evaluation of perceived spatial quality calls for a method that is sensitive to changes in the constituent dimensions of that quality. In order to devise a method accounting for these changes, several processes have to be performed. This paper shows the development of scales by elicitation and structuring of verbal data, followed by validation of the resulting attribute scales.

    Kombinerade mobilitetstjänster pålandsbygd och i mindre tätorter– resultat från förstudien KomILand2018Report (Other academic)
    Abstract [en]

    Different types of mobility services in small towns and rural areas can increase accessibility among theresidents and reduce the need to travel by one’s own car. The purpose of this pre-study is to preparefor future demonstration projects for combined mobility (CM) in small towns and rural areas byproviding data on location, users, services and financing. Several activities have been carried out:identification of geographically appropriate areas and ongoing projects worldwide; analysis of userneeds; identification of service design and business models; and mobilization of local and regionalinvolvement. Services and business models have been developed using The Osterwalder BusinessModel Canvas. Several characteristics have been identified that a small town or rural area should havein order for CM to function. Services that could be included in a service package in a CM rural servicehave been validated theoretically in the fictional town of Småtorp. A public actor needs to provideorganisational and digital platforms to local organisations, and KomILand-consultants. KomILand cancontribute profitability, reduce mobility costs for customers, contribute new customers to the publictransport operators, and lead to increased sustainability for society, if there is a robust and qualitativepublic transport system as a basis

    Forces between surfaces coated with a polymerizable surfactant before and after polymerization1994In: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 163, p. 289-298Article in journal (Refereed)
    Abstract [en]

    The forces between layers of a cationic polymerizable surfactant, cetyl p-vinylbenzyl dimethyl ammonium chloride (CVDAC), adsorbed onto muscovite mica have been measured with a surface force technique. The forces were measured both prior to and after partial W polymerization of the adsorbed layers, and the stability of adsorbed bilayers after dilution of the adsorption solution was studied for these two cases. Due to their large headgroup, CVDAC molecules do not pack efficiently into monolayers and bilayers. This can be observed by, for instance, the lower surface potential of adsorbed bilayers and the lower pull-off force from monolayer contact, compared to what is found for simpler surfactants like CTAB. It was also found that surface aggregates build up on top of the bilayer, due to the partly hydrophobic headgroup. When the bilayer structure, including the surface aggregates, is polymerized, it is stabilized both with respect to mechanical forces and with respect to dilution of the surrounding solution

    Interactions between mica surfaces in sodium polyacrylate solutions containing calcium ions1993In: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 161, p. 182-189Article in journal (Refereed)
    Abstract [en]

    The forces acting between negatively charged muscovite mica surfaces immersed in solutions containing sodium polyacrylate (NaPAA) have been studied. No evidence for PAA adsorption in the absence of calcium ions in the solution was found. However, at a CaCl2 concentration of about 3x10-3 M a layer of PAA adsorbed on each surface. At large separations, the forces between the PAA-coated surfaces were dominated by repulsive double-layer forces. At separations below 50-80 Å, depending on the solution conditions, an attractive force in excess of the van der Waals attraction was observed. The adhesion force between the layers was 7-8 mN/m at pH 6 and increased somewhat with increasing pH to about 9 mN/m at pH 10. We argue that both the long-range attraction and the adhesion force primarily are due to COO- - Ca2+ --OOC bridges between the opposing surfaces and possibly charge correlation effects. It was found that calcium ions bind to the PAA and to the mica surface, whereby the electrostatic repulsion between the polyelectrolyte and the surface is lowered. We suggest that this is the main re ason why Calcium ions promote the adsorption of PAA onto negatively charged minerals. However, it also seems likely that calcium ions increase the attractive interactions between the surface and the PAA segments.

    Mixed monolayers and Langmuir-Blodgett films consisting of a fatty amine and a bipolar substance1994In: Langmuir, ISSN 0743-7463, E-ISSN 1520-5827, Vol. 10, p. 1213-1224Article in journal (Refereed)
    Abstract [en]

    The properties of two types of two-component spread monolayers at the air/water interface, docosanedioic acid/eicosylamine (DDA/EA) and 1,22-docosanediol/eicosylamine (DDO/EA), were investigated at different mixing ratios. The monolayers were studied by surface pressure-area isotherms, constant surface pressure-area relaxation isotherms and deposition onto muscovite mica with subsequent contact angle measurements. The two types of monolayers were found to behave very differently, but in both cases one of the polar groups of the bipolar substance was situated at the air side of the monolayer after compression. At moderate DDA ratios, the surface pressure-area isotherms of DDA/EA displayed a plateau, low mean molecular area for the condensed phase, and the relaxation isotherms at low surface pressures had an unusually long induction time. DDO/EA showed much less complexity in its behaviour. These differences are explained by the difference in headgroup interaction strength, which are strong for DDA/EA case (acid-amine) and weak for DDO/EA (hydroxy-amine). Due to the increased polarity/low contact angle during the deposition, the DDA/EA monolayers at DDA ratios above 50 % deposited as Z-type Langmuir-Blodgett multilayers onto mica.

    Three-component Langmuir-Blodgett films with a controllable degree of polarity1994In: Langmuir, ISSN 0743-7463, E-ISSN 1520-5827, Vol. 10, p. 1225-1234Article in journal (Refereed)
    Abstract [en]

    Two different series of mixed Langmuir-Blodgett (LB) films with a controllable degree of polarity, deposited on mica, have been studied by wetting and surface force techniques. Both series contain of 50% eicosylamine (EA). Films of one series consist of EA, arachidic acid and docosanedioic acid, while those of the other consist of EA, 1-eicosanol and 1,22-docosanediol. Carboxylic acid groups give lower contact angles than hydroxy groups. Concerning the stability of the LB films in aqueous solutions, repeated exposure to a three-phase line and high salt solutions were found to cause breakdown. Surface force measurements on carboxylic acid-containing films show that films with a 0% (contact angle = 113°) and 25% (contact angle ≈ 90°) content of diacid interact with a long-range (hydrophobic) attraction across water. No similar long-range attraction is observed for the 50% case (contact angle ≈ 65°). Surface force measurements also detected instabilities and imperfections of the films.

    State of the Art Report Insects as Food and Feed2017In: Annals of Experimental Biology, ISSN ISSN:2348-1935, Vol. 5, no 2, p. 37-46Article in journal (Refereed)
    Abstract [en]

    FAO has considered insects as food since 2003 and is promoting consumption of insects (entomophagy) in the Western world because of the possibilities for sustainable production it offers. Insects as food are considered to leave smaller ecological footprints than conventional livestock (beef, pigs, and poultry) regarding feed, land and water needs, as well as greenhouse gas and ammonia emissions. As an example regarding water, taken from a recent TV documentary, if a family of four people got their protein need from insects one day a week instead of from conventional livestock, over a year they would save the planet about a million Liters of water. This is in agreement with figures above. One of the main reasons that insects for food in general have such positive environmental properties is that they are cold-blooded and thus use no energy to maintain their body temperature, in contrast to mammals (beef, pig) and birds (poultry), so their feed conversion is considerably more effective than that of conventional livestock. However, differences in feed conversion may also have other reasons, and are complicated to explain, as discussed in a recent review of Life Cycle Assessments of edible insects [9]. In addition, insects can be reared on organic side streams. For example, mealworms can recycle organic residues into high-quality potential feed rich in energy, protein and fat. Insects as food are generally considered as healthy, nutritious alternatives to conventional meats such as chicken, pork, and beef. They are rich in protein, 40-60% of dry matter, with content of essential amino acids similar to beef and soy. Unsaturated fat content is 10-30% of dry matter, and they are high in calcium, iron and zinc. However, there are significant differences depending on insect species, rearing method and feed, etc. .

    Mellanlagring av sågat virke - inverkan på kvaliteten efter torkning1998Report (Other academic)
    Abstract [sv]

    Det finns idag önskemål om att kvalitetssortera redan före torkning. För att kunna göra det måste man veta kur kvaliteten på virket påverkas av mellanlagring mellan såghus och torkhus samt av torkningsprocessen. I detta examensarbete har man studerat vilken inverkan mellanlagringen har på den relativa spricklängden före och efter torkning.

    Utrustningar för berörande längd- och diametermätning på skogsmaskiner1991Report (Other academic)
    Abstract [sv]

    Flertalet skördare förses idag med apteringsdatorer. Om apteringsutrustningen skall betala sig krävs det bl a att givarsystemen är tillförlitliga. Trätek har studerat de vanligaste en- och tvågreppsaggregaten och kontrollerat givarsystemens mätprestanda, konstruktion och tillgänglighet. Inga av aggregaten uppfyller de krav som skogsbruket ställer på längdmätning. Tvågreppsaggregaten mäter dock längd bättre än engreppsaggregaten vilket talar för att dessa i första hand skall användas i slutavverkning. Inga aggregat uppfyller heller de krav som ställs på diametermätning. Mätning av diametern med kvistknivar verkar generellt ge den bästa mätningen, under förutsättning att man använder båda knivarna. Att mäta med enbart en kniv ger dålig mätning.
