    Ett mätsystem för att bestämma glukoskoncentration baserat på en mikrovågsresonator och homodyn detektering2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this work I have evaluated a measurement method for glucose concentration in aqueous solutions and developed a system that performs the measurement and presents the result on a computer screen.

    The method is based on the dielectric properties of glucose and the varying phase shift of a microwave resonance cavity. The phase shift is measured using homodyne detection.

    The measurement system can measure the concentration of glucose in aqueous solutions in real time. I have tested concentrations from 0 to 3000 mg/dl.

    Wave Phenomena and Beam-Plasma Interactions at the Magnetopause Reconnection Region2018In: Journal of Geophysical Research - Space Physics, ISSN 2169-9380, E-ISSN 2169-9402, Vol. 123, no 2, p. 1118-1133Article in journal (Refereed)
    Abstract [en]

    This paper reports on Magnetospheric Multiscale observations of whistler mode chorus and higher-frequency electrostatic waves near and within a reconnection diffusion region on 23 November 2016. The diffusion region is bounded by crescent-shaped electron distributions and associated dissipation just upstream of the X-line and by magnetic field-aligned currents and electric fields leading to dissipation near the electron stagnation point. Measurements were made southward of the X-line as determined by southward directed ion and electron jets. We show that electrostatic wave generation is due to magnetosheath electron beams formed by the electron jets as they interact with a cold background plasma and more energetic population of magnetospheric electrons. On the magnetosphere side of the X-line the electron beams are accompanied by a strong perpendicular electron temperature anisotropy, which is shown to be the source of an observed rising-tone whistler mode chorus event. We show that the apex of the chorus event and the onset of electrostatic waves coincide with the opening of magnetic field lines at the electron stagnation point.

    Multiscale Currents Observed by MMS in the Flow Braking Region2018In: Journal of Geophysical Research - Space Physics, ISSN 2169-9380, E-ISSN 2169-9402, Vol. 123, no 2, p. 1260-1278Article in journal (Refereed)
    Abstract [en]

    We present characteristics of current layers in the off-equatorial near-Earth plasma sheet boundary observed with high time-resolution measurements from the Magnetospheric Multiscale mission during an intense substorm associated with multiple dipolarizations. The four Magnetospheric Multiscale spacecraft, separated by distances of about 50 km, were located in the southern hemisphere in the dusk portion of a substorm current wedge. They observed fast flow disturbances (up to about 500 km/s), most intense in the dawn-dusk direction. Field-aligned currents were observed initially within the expanding plasma sheet, where the flow and field disturbances showed the distinct pattern expected in the braking region of localized flows. Subsequently, intense thin field-aligned current layers were detected at the inner boundary of equatorward moving flux tubes together with Earthward streaming hot ions. Intense Hall current layers were found adjacent to the field-aligned currents. In particular, we found a Hall current structure in the vicinity of the Earthward streaming ion jet that consisted of mixed ion components, that is, hot unmagnetized ions, cold ExB drifting ions, and magnetized electrons. Our observations show that both the near-Earth plasma jet diversion and the thin Hall current layers formed around the reconnection jet boundary are the sites where diversion of the perpendicular currents take place that contribute to the observed field-aligned current pattern as predicted by simulations of reconnection jets. Hence, multiscale structure of flow braking is preserved in the field-aligned currents in the off-equatorial plasma sheet and is also translated to ionosphere to become a part of the substorm field-aligned current system.

    Quality and learning aspects of the first 9000 spirometries of the LifeGene study2018In: NPD Bulletin, ISSN 1892-8110, E-ISSN 2055-1010, Vol. 28, article id 6Article in journal (Refereed)
    Abstract [en]

    Spirometry requires the patient to cooperate and do the manoeuvre 'right' for reliable results. Algorithms to assess test quality as well as educational recommendations for personnel are defined in guidelines. We compared the quality of forced spirometry tests performed by spirometry technicians with little or no previous experience of spirometry using spirometry systems with different modes of feedback. In both cases, the spirometry technician received general feedback on the screen based on ATS/ERS guidelines, such as 'exhale faster' and 'exhale longer'. The major difference was whether quality grading system of the complete session was available simultaneously on screen, or in the printed report afterwards. Two parts of the same population-based study (LifeGene), the pilot (LG1) and the first part (LG2) of the subsequent study, were compared retrospectively. In LG1 (on-screen grading) approved examination quality was achieved for 88% of the 10 first subjects for each spirometry technician compared to 70% in LG2 (printed grading afterwards). The corresponding values after 40 subjects was 94 % in LG1, compared to 73% in LG2, and after the first ten subjects there was no apparent quality improvement in either LG1 or LG2. The quality for LG1 is among the highest reported in the literature even though the spirometry technician were relatively inexperienced. We conclude that on-screen grading in addition to general technical quality feedback is powerful in enhancing the spirometry test session quality.

    Measurement of quarkonium production in proton-lead and proton-proton collisions at 5.02 TeV with the ATLAS detector2018In: European Physical Journal C, ISSN 1434-6044, E-ISSN 1434-6052, Vol. 78, no 3, article id 171Article in journal (Refereed)
    Abstract [en]

    The modification of the production of J/psi, psi(2S), and gamma (nS) (n = 1, 2, 3) in p+Pb collisions with respect to their production in pp collisions has been studied. The p+Pb and pp datasets used in this paper correspond to integrated luminosities of 28 nb(-1) and 25 pb(-1) respectively, collected in 2013 and 2015 by the ATLAS detector at the LHC, both at a centre-of-mass energy per nucleon pair of 5.02 TeV. The quarkonium states are reconstructed in the dimuon decay channel. The yields of J/psi and psi(2S) are separated into prompt and non-prompt sources. The measured quarkonium differential cross sections are presented as a function of rapidity and transverse momentum, as is the nuclear modification factor, R-pPb for J/psi and psi (nS). No significant modification of the J/psi production is observed while gamma (nS) production is found to be suppressed at low transverse momentum in p+Pb collisions relative to pp collisions. The production of excited charmonium and bottomonium states is found to be suppressed relative to that of the ground states in central p+Pb collisions.

    Geotermisk förvärmning av ventilationsluft: En utvärdering av ventilationssystemets energieffektivitet2018Independent thesis Advanced level (professional degree), 300 HE creditsStudent thesis
    Abstract [en]

    This master thesis examines the energy efficiency of preheating outdoor air in ventilation systems by using geothermal heat from boreholes. Energy efficiency in this context only relates to minimise the energy consumption and to minimise the peak power consumption during cold days. Preheating the outdoor air before it enters the heat exchanger is a techinque that is used to avoid frost formation in the heat exhanger. The aim of preheating the outdoor air is to reduce the energy consumption in the buidling and to reduce the peak power consumption during cold days. In this project a buliding in Töfsingdalen, Stockholm, is investigated. In one part of the building the outdoor air is preheated while the air in another part of the building is not. The investigation is partly based on an analysis of measured temperaures in the building’s ventilation system during 2017. The results of the analysis show that the heat exchanger in the air-handling unit with preheating has not been defrosted during the investigated period.

    In this thesis, models are also constructed to simulate the system. The models are created in the simulation programme IDA ICE, wich is a simulation tool for bulidings. The simulations show that the total energy consumption is 1.2 kWh/m2Atemp, year higher and the maximal power consumption is 18 kW lower for the system that preheats the outdoor air compared to the system without preheating. In addition to this, the conclusion of this report is that the energy efficiency of preheating the outdoor air depends on the type of heat exchanger. A heat exchanger with high efficiency results in a lower peak power consumption than a heat exchanger wth a lower efficiency. Futhermore, the results show that geothermal preheating is better from an energy perspective when heat exchangers with moderate as opposed to high efficiencies are used. The energy efficiency of preheating outdoor air in ventilation systems also depends on the outdoor climate and the control strategy of the preheating. In this report, the control strategy for the preheating system in Töfsingdalen has been optimised in order to reduce the energy consumption in the building.

    Sandgrunnorna in Lule Archipelago: Recent Transformation of a Glaciofluvial Deposit in an Environment of Land Uplift1985Licentiate thesis, monograph (Other academic)
    Abstract [en]

    In an area of rapid land uplift the geomorphological evolution of the glaciofluvial island of Sandgrunnorna, 25 km SE Luleå, in the Bothnian Bay, is discussed from old maps, air photographs and field studies. The island were marked on a map for the first time in 1790, but the highest parts can be estimated to have reached the sea surface about 100 years earlier. The areal growth has been reconstructed by map and air photograph studies. A model of the geomorphological evolution based on the interaction between bottom morphology, land uplift and waves is presented.

    Online-instrumentering på avloppsreningsverk: status idag och effekter av givarfel på reningsprocessen2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The effectiveness of automated treatment processes within wastewater treatment plants ultimately depend on the quality of the measurement data that is given from the installed sensors. Sensor faults affect the control of the treatment plants and are often the reason different control strategies fail. Today there is a lack of standardized guidelines for how to organize and work with online sensors at Swedish wastewater treatment plants which limits the opportunities for treatment plants to reach their effluent criteria in a resource efficient manner. Much research has been done on ways to optimize control strategies but the role of sensors in the efficiency of the treatment plants has not been given the same level of attention. The purpose of this thesis has been to examine how instrumentation at wastewater treatment plants can be organized and structured to ensure good quality measurement data and to examine how sensor faults affect the treatment process.

    Within the thesis a literature study was conducted where instrumentation at wastewater treatment plants was examined. The effects of sensor faults were examined by simulating a pre-denitrification process in Benchmark Simulation Model no. 2 where off-sets (biases) and drift where added to measurements from different implemented sensors. The simulations showed that positive off-sets (0.10–0.50 mg/l) in an ammonium sensor within a cascaded feedback-loop adds to the energy consumption used for aeration by roughly 4-25%. It could further be shown that all types of faults in a DO sensor in the last aerated basin had significantly larger effect on the treatment process than the same fault in any of the other DO sensors in the preceding basins. If the last aerated basin is designed to have low DO concentrations the DO sensor in that basin is the most important DO sensor to maintain. Positive off-sets (200–1 000 mg TSS/l) in suspended solids sensors used for control of waste activated sludge flow contributed to large increases of ammonia, by 29-464%, in effluent waters. Negative drift in DO sensors showed that significant savings in aeration energy, roughly 4%, was possible to achieve with more frequent maintenance.

    Whether a sensor is affected by a positive or a negative fault, be it off-set or drift, will affect how much and in what way the treatment process will be affected. The study of sensor faults showed that the effect of a positive or a negative fault varied and that the effect on the treatment process was not linear. The effect of a sensor fault on the treatment process will ultimately depend on the implemented control strategy, settings in the controllers and on the controlled process.

    Towards a Zero Waste Vision using Insects – Urban Farming producing New Values in a Swedish Supermarket2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The premise of the thesis is that current food systems are unsustainable. In fact, as the global population continues to rise, food systems are under greater strain to deliver quality output in a sustainable way. In sustainable food systems, effective use of agricultural land and reducing food waste are central, as stipulated by Agenda 2030 target to reduce food waste by 50 % to 2030. Insects have gained attention for their ability to effectively convert feed, including feed from food waste, to edible products. Framed by a literature review and an analysis of food waste data from a Swedish supermarket, the ability to rear three insect species, House Cricket (Acheta Domesticus), Yellow Mealworm (Tenebrio Molitor) and Black Soldier fly (Hermetia Illucens) on food waste is examined. The three insect species with the addition of laying hens are also the grounding for evidence-based scenarios. The results indicate that the Black Solider Fly can be reared on unprocessed food waste while the House Cricket requires food waste treated for higher levels of protein and phosphorus and the Yellow Mealworm food waste supplemented by external products such as yeast, carrots or wheat bran. The result from the scenarios shows that substantial amounts of edible output can be produced by providing the insects and laying hens vegetable food waste from the supermarket. The conclusion of this thesis highlights the potential of using insects and laying hens as feed converters in integrated production systems to recover energy and nutrients from food waste and thereby contribute to a food system that produces more output using less land and with less negative environmental impact.

    Accumulation by Conservation: Conflicts between aquaculture, protected mangroves and small-scale fisheries in Marismas Nacionales, Mexico2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Brackish water ecosystems such as mangroves are among the most biodiverse in the world. The mangroves located in the Gulf of California, Mexico are not an exception. This sea has been studied several times due to its biodiverse coastal ecosystems, one of these sites being “Marismas Nacionales” or National Marshes in the southeast area of the Gulf, which was the focus of the thesis. Local fishing communities have been present in the area since pre-Hispanic times and the area became recognized for their abundant oyster, shrimp, and finfish yields during the XX century. Overexploitation of fisheries in Mexico and national financial crisis opened the door to neoliberal policy and law reforms which affected directly and still affect the subsistence, economy and political power of the fishers in the area. Because of the neoliberal reforms, shrimp aquaculture became an important economic activity in and around the region of Marismas Nacionales by the end of the 1980s. By the 1990s international and national protection, instruments were implemented to revert the damages and pressures created by overexploited fishers, as well as by the new aquaculture practices introduced in the ecosystem, giving Marismas Nacionales the status of the biosphere reserve. The figure of biosphere reserve has reverted the damages in the ecosystem while preserving the communal land inside of it. Nevertheless, since the biosphere reserve does not cover the whole ecosystem, the political boundaries of the biosphere reserve have also been detrimental for the ecosystem and local fishers’ land tenure that remained outside of it, creating an inside/outside effect. The study was done considering the perspectives of the actors involved, mainly the fishers in the area through semi-structured interviews gathered using a snowball method, through second-hand sources collection and literature review. The analysis was done through the political ecology and political economy perspectives to examine the conflicts that were found. The neoliberal laws from the period between 1986 and 1992 have not stopped the depletion of fisheries in the Marismas Nacionales ecosystem. Additionally, with the combination of a lack of formal credit schemes leading to an exploitation by permit holders and middlemen; fishers, in particular, free fishers, in the Marismas Nacionales ecosystem have become vulnerable, as well as scapegoats for the shortcomings of the flawed policies. The most affected fishers inside Marismas Nacionales ecosystem where found outside the limits of the biosphere reserve, demonstrating the deficiencies of the biosphere reserve. Additionally, I claim that conservation instruments and areas around Mexico could potentially become part of a process of primitive accumulation which could end up in privatizing those areas as seen in other places around the world. Moreover, shrimp aquaculture seems to benefit from the conservation policies. Further research is advised in regulatory processes and conservation law schemes, as well as an accurate implementation in the Marismas Nacionales wetlands, that considers all those implicated.

    Healthcare students perception of their readiness for interprofessional learning2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Interprofessional Learning (IPL) is an approach that teaches students from different disciplines to share their professional knowledge in order to gain a more complex understanding of the situation at hand. According to WHO, interprofessional learning strengthens communication and the collaborative practice which in turn improves health outcomes for patients. Insufficient interprofessional communication due to inexperience with interprofessional teamwork can affect patients’ safety.

    Aim: To compare differences in nursing- and medical students readiness for interprofessional learning in Vietnam and if they believe that IPL could affect the quality of communication with patients.

    Method: A quantitative study was conducted, with a descriptive approach where the population consisted of nursing- and medical students at University of Medicine and Pharmacy in Ho Chi Minh City, Vietnam. The data was collected through a structured questionnaire called Readiness for Interprofessional Learning Scale (RIPLS). Mann Whitney U-test was used for statistical analyzes.

    Results: A statistical significant difference, between the two professions, was found in four out of nineteen questions. Therefore we could not see a difference in readiness between the two professions. Regarding the students’ perception on IPL and communication, we could not see a statistical difference, the two groups had similar views on the topic.

     

    Conclusion: We could only find a few questions that reflected an actual difference (p < 0.05) in opinion between the two professions.

    RÄCKER STÖDEN TILL?: En paneldatastudie om effekter av ekonomiska stöd till mjölkproducenter2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det har under många år funnits olika former av ekonomiska stöd till jordbrukare i Sverige. På grund av olika produktionsförutsättningar orsakade av naturliga begränsningar ges regionala stöd till bland annat mjölkproducenter i delar av Sverige. Genom att utföra fixed-effect-regressioner, utifrån paneldata med Sveriges alla kommuner under åren 2001–2013, undersöks effekterna av det nationella stödet och kompensationsstödet på antalet mjölkproducenter och volymen producerad mjölk. Resultaten visar att det nationella stödet har en positiv effekt på antalet mjölkproducenter och mjölkinvägningen i Sverige. Kompensationsstödet verkar inte ha någon ekonomisk effekt på någon av de två beroende variablerna.

    Berättelser bortom det könsbinära - transrepresentation i barnlitteratur: En text- och innehållsanalys av böcker om transpersoner för förskolebarn2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The objective of the following essay is to investigate in what way trans- and nonbinary people are portrayed in children’s literature. It aims to answer questions such as in what way the trans characters in the books examined are portrayed, and which stories and narratives are being told and reproduced, as well as which stories are missing or get neglected. The method used here is content analysis, in which twelve books make out the material for analysis. Out of these twelve, four books are analysed further and are presented in a more detailed manner. The content analysis is carried out by examining the literature based on how the stories are affected by their trans characters and how, if at all, the word trans is used by the author. In the result, the literature is categorized depending on where the focus of the story lies – and how the story is connected to the trans character in question. We learn that most of the books at hand can be classified as books without a focus on trans themes, and the remaining books either have a symbolic focus on trans themes, or a story mainly focused on a character being trans. This essay then discusses if literature with less outspoken trans themes are more attractive to conservative publishers, and why some of the literature with more uncommon themes are, as such, uncommon. The discussion also shines a light on the portrayal of nonbinary people, and raises questions regarding how we view gender based on looks and stereotypically gendered items. In conclusion, the essay finds that the books analysed here fails to show the diversity found in the trans community and in the way trans- and nonbinary people exist.

    Cholesterol enhances influenza binding avidity by controlling nanoscale receptor clustering2018In: Chemical Science, ISSN 2041-6520, E-ISSN 2041-6539, Vol. 9, no 8, p. 2340-2347Article in journal (Refereed)
    Abstract [en]

    Influenza virus infects cells by binding to sialylated glycans on the cell surface. While the chemical structure of these glycans determines hemagglutinin-glycan binding affinity, bimolecular affinities are weak, so binding is avidity-dominated and driven by multivalent interactions. Here, we show that membrane spatial organization can control viral binding. Using single-virus fluorescence microscopy, we demonstrate that the sterol composition of the target membrane enhances viral binding avidity in a dose-dependent manner. Binding shows a cooperative dependence on concentration of receptors for influenza virus, as would be expected for a multivalent interaction. Surprisingly, the ability of sterols to promote viral binding is independent of their ability to support liquid-liquid phase separation in model systems. We develop a molecular explanation for this observation via molecular dynamics simulations, where we find that cholesterol promotes small-scale clusters of glycosphingolipid receptors. We propose a model whereby cholesterol orders the monomeric state of glycosphingolipid receptors, reducing the entropic penalty of receptor association and thus favoring multimeric complexes without phase separation. This model explains how cholesterol and other sterols control the spatial organization of membrane receptors for influenza and increase viral binding avidity. A natural consequence of this finding is that local cholesterol concentration in the plasma membrane of cells may alter the binding avidity of influenza virions. Furthermore, our results demonstrate a form of cholesterol-dependent membrane organization that does not involve lipid rafts, suggesting that cholesterol's effect on cell membrane heterogeneity is likely the interplay of several different factors.

    Quality and learning aspects of the first 9000 spirometries of the LifeGene study2018In: NPJ primary care respiratory medicine, ISSN 2055-1010, Vol. 28, article id 6Article in journal (Refereed)
    Abstract [en]

    Spirometry requires the patient to cooperate and do the manoeuvre 'right' for reliable results. Algorithms to assess test quality as well as educational recommendations for personnel are defined in guidelines. We compared the quality of forced spirometry tests performed by spirometry technicians with little or no previous experience of spirometry using spirometry systems with different modes of feedback. In both cases, the spirometry technician received general feedback on the screen based on ATS/ERS guidelines, such as 'exhale faster' and 'exhale longer'. The major difference was whether quality grading system of the complete session was available simultaneously on screen, or in the printed report afterwards. Two parts of the same population-based study (LifeGene), the pilot (LG1) and the first part (LG2) of the subsequent study, were compared retrospectively. In LG1 (on-screen grading) approved examination quality was achieved for 88% of the 10 first subjects for each spirometry technician compared to 70% in LG2 (printed grading afterwards). The corresponding values after 40 subjects was 94 % in LG1, compared to 73% in LG2, and after the first ten subjects there was no apparent quality improvement in either LG1 or LG2. The quality for LG1 is among the highest reported in the literature even though the spirometry technician were relatively inexperienced. We conclude that on-screen grading in addition to general technical quality feedback is powerful in enhancing the spirometry test session quality.

    Identifying Medication History Errors at Iraqi Hospital Admissions Using The Swedish-LIMM model2016Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Background and Objective: An accurate medication history list is an integral part of the patient assessment at hospital admission. The objective of the study was to describe the frequency, type, and predictors of unintentional medication errors and to evaluate the quality of the clinical pharmacy services focusing on the acceptance of the recommendations made by the clinical pharmacist.

    Setting and methods: A descriptive study was conducted at two internal medicine wards at Baghdad Teaching Hospital in Iraq using Lund Integrated Medicines Management (LIMM)-based medication reconciliation. The study pharmacist conducted medication interviews for patients shortly after hospital admission to obtain the most accurate pre-admission medication history list. This list was compared with the medication list in the patient’s medical chart. Intended addition, withdrawal of a drug, or changes to the dose/ dosage form in the patient’s medical list was considered as medication discrepancies. However, medication discrepancies were considered as medication errors based on no identified clinical reason.

    Results: A total of 114 patients were included in this study. Over two-thirds of the study patients (73.7%) experienced 215 medication errors identified by a clinical pharmacist conducting medication reconciliation. Most errors were omission (87.9%). Cardiovascular agents followed by NSAID were commonly in error (53%) and (10.2%) respectively. In a logistic regression model, age (odds ratio (OR), 1.055: 95% confidence interval (CI) 1.010 - 1.102), female gender (OR, 3.468: 95% CI 1.232- 9.761) and number of medications at admission (OR, 0.810: 95% CI 0.681-0.963) were predictors for medication history errors at admission.

    Conclusions: Medication errors at the time of hospital admission are common and undetected.  A structured approach like the LIMM-based medication reconciliation at Iraqi hospital is needed to detect these errors.

    Pollinator-mediated selection and the evolution of floral traits in orchids2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In this thesis, I combined manipulations of traits and pollination environment with analysis of phenotypic selection to examine causes of variation in strength and mode of selection on floral traits, and I conducted a reciprocal sowing experiment to test for local adaptation in germination success. I tested the following predictions (1) the opportunity for selection, and the strength of pollinator-mediated and net selection increase with increasing pollen limitation, (2) the effects of traits affecting pollinator attraction and traits affecting pollination efficiency are non-additive and this leads to pollinator-mediated correlational selection, (3) the effects of spur length on pollen removal, pollen receipt, and female fitness differ between populations with short-tongued and populations with long-tongued pollinators, and (4) local adaptation at the stage of germination contributes to the maintenance of ecotypes growing in grasslands and woodlands, respectively.

    A study including natural populations of 12 orchid species that varied widely in pollen limitation showed that opportunity for selection, pollinator-mediated selection and net selection were all positively related to pollen limitation, whereas non-pollinator-mediated selection was not. In the moth-pollinated orchid Platanthera bifolia, experimental reductions of plant height and spur length decreased pollen removal, pollen receipt and fruit production, but non-additive effects were not detected. Effects of plant height translated into pollinator-mediated selection for taller plants via female fitness, but there was no current pollinator-mediated selection on spur length. An experiment using artificial nectar spurs demonstrated that in P. bifolia pollen receipt saturated at shorter spur length in a population with short-tongued pollinators than in a population with a long-tongued pollinator. Effects of spur length on pollen receipt did not translate into current pollinator-mediated selection indicating that also plants with the shortest spurs for the most part received sufficient pollen for full seed set. Reciprocal sowing of seeds from grassland and woodland populations detected no evidence of local adaptation at the germination stage between ecotypes of P. bifolia.

    Taken together, the results illustrate how a combination of trait manipulation and analysis of strength and causes of selection can throw light on both the functional and adaptive significance of trait variation within and among natural populations.

    Abstract [en]

    In animal-pollinated plants, the opportunity for selection and the strength of pollinatormediated selection are expected to increase with the degree of pollen limitation. However, whether differences in pollen limitation can explain variation in pollinator-mediated and net selection among animal-pollinated species is poorly understood. In the present study, we quantified pollen limitation, variance in relative fitness and pollinator- mediated selection on five traits important for pollinator attraction (flowering start, plant height, flower number, flower size) and pollination efficiency (spur length) in natural populations of 12 orchid species. Pollinator-mediated selection was quantified by subtracting estimates of selection gradients for plants receiving supplemental hand-pollination from estimates obtained for open-pollinated control plants. Mean pollen limitation ranged from zero to 0.96. Opportunity for selection, pollinatormediated selection and net selection were all positively related to pollen limitation, whereas nonpollinator-mediated selection was not. Opportunity for selection varied five-fold, strength of pollinator-mediated selection varied three-fold and net selection varied 1.5-fold among species. Supplemental hand-pollination reduced both opportunity for selection and selection on floral traits. The results show that the intensity of biotic interactions is an important determinant of the selection regime, and indicate that the potential for pollinator-mediated selection and divergence in floral traits is particularly high in species that are strongly pollen-limited.

    Unintentional Childhood Injuries in Urban and Rural Ujjain, India: A Community-Based Survey2018In: Children (Basel), ISSN 2227-9067, Vol. 5, no 2, article id 23Article in journal (Refereed)
    Abstract [en]

    Injuries are a major global public health problem. There are very few community-based studies on childhood injury from India. The objective of this cross-sectional, community-based survey was to identify the incidence, type, and risk factors of unintentional childhood injuries. The study was done in seven villages and ten contiguous urban slums in Ujjain, India. World Health Organization (WHO) tested tools and definitions were used for the survey, which included 2518 households having 6308 children up to 18 years of age, with 2907 children from urban households and 3401 from rural households. The annual incidence of all injuries was 16.6%, 95% Confidence Interval 15.7-17.5%, (n = 1049). The incidence was significantly higher among boys compared to girls (20.2% versus 12.7%, respectively), was highest in age group 6-10 years of age (18.9%), and in urban locations (17.5%). The most commonly identified injury types were: physical injuries (71%), burns (16%), poisonings (10%), agriculture-related injuries (2%), near drowning (2%), and suffocations (2%). The most common place of injury was streets followed by home. The study identified incidence of different types of unintentional childhood injuries and factors associated with increased risk of unintentional injuries. The results can help in designing injury prevention strategies and awareness programs in similar settings.

    Forward to a Promising Future2018In: Conference proceedings COORDINATION 2018, 2018Conference paper (Refereed)
    Abstract [en]

    In many actor-based programming models, asynchronous method calls communicate their results using futures, where the fulfilment occurs under-the-hood. Promises play a similar role to futures, except that they must be explicitly created and explicitly fulfilled; this makes promises more flexible than futures, though promises lack fulfilment guarantees: they can be fulfilled once, multiple times or not at all. Unfortunately, futures are too rigid to exploit many available concurrent and parallel patterns. For instance, many computations block on a future to get its result only to return that result immediately (to fulfil their own future). To make futures more flexible, we explore a construct, forward, that delegates the responsibility for fulfilling the current implicit future to another computation. Forward reduces synchronisation and gives futures promise-like capabilities. This paper presents a formalisation of the forward construct, defined in a high-level source language, and a compilation strategy from the high-level language to a low-level, promised-based target language. The translation is shown to preserve semantics. Based on this foundation, we describe the implementation of forward in the parallel, actor-based language Encore, which compiles to C.

    Highly Concentrated Electrolytes for Lithium Batteries: From fundamentals to cell tests2018Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The electrolyte is a crucial part of any lithium battery, strongly affecting longevity and safety. It has to survive rather severe conditions, not the least at the electrode/electrolyte interfaces. Current commercial electrolytes based on 1 M LiPF 6 in a mixture of organic solvents balance the requirements on conductivity and electrochemical stability, but they are volatile and degrade when operated at temperatures above ca. 70°C. The salt could potentially be replaced with e.g. LiTFSI, but corrosion of the aluminium current collector is an issue. Replacing the graphite negative electrode by Li metal for large gains in energy density challenges the electrolyte further by exposing it to freshly deposited Li, leading to poor coulombic efficiency (CE) and consumption of both Li and electrolyte. Highly concentrated electrolytes (up to > 4 M) have emerged as a possible remedy, by a changed solvation structure such that all solvent molecules are coordinated to cations – leading to a lowered volatility and melting point, an increased charge carrier density and electrochemical stability, but a higher viscosity and a lower ionic conductivity.

    Here two approaches to highly concentrated electrolytes are evaluated. First, LiTFSI and acetonitrile electrolytes with respect to increased electrochemical stability and in particular the passivating solid electrolyte interphase (SEI) on the anode is studied using electrochemical techniques and X-ray photoelectron spectroscopy. Second, lowering the liquidus temperature by high salt concentration is utilized to create an electrolyte solely of LiTFSI and ethylene carbonate, tested for application in Li metal batteries by characterizing the morphology of plated Li using scanning electron microscopy and the CE by galvanostatic polarization. While the first approach shows dramatic improvements, the inherent weaknesses cannot be completely avoided, the second approach provides some promising cycling results for Li metal based cells. This points towards further investigations of the SEI, and possibly long-term safe cycling of Li metal anodes.

    Breastfeeding – Initiation, duration, attitudes and experiences2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The overall aim of this thesis was to increase knowledge about factors that influence breastfeeding initiation and duration, as well as about women’s attitudes towards breastfeeding during pregnancy.

    The first two studies were a part of the UPPSAT project, a population-based cohort study conducted in Uppsala, Sweden. The women answered questionnaires five days, six weeks and six months postpartum, including questions on breastfeeding initiation and duration. Eight hundred and seventy-nine women and 679 women were included in the first study (Paper I) and second study (Paper II), respectively. The third study (Paper III) was part of the BASIC study, a large cohort following women from pregnancy and up to one year postpartum. In BASIC, the women completed web-questionnaires, and 1217 women participated during mid-pregnancy and postpartum. The fourth study (Paper IV) was part of a qualitative project, “Narratives of breastfeeding”, and included 11 women, interviewed individually in late pregnancy.

    The prevalence of the hands-on approach was 38%. Women who received the hands-on approach were more likely to report a negative experience of the first breastfeeding session (Paper I). Seventy-seven percent of the women reported exclusive breastfeeding up to, at least, two months postpartum. Being a first-time mother, reporting emotional distress during pregnancy, and giving birth by cesarean section were factors independently associated with exclusive breastfeeding lasting less than two months postpartum (Paper II). Women with depressive symptoms during pregnancy who breastfed for the first time later than two hours postpartum had the highest odds of not breastfeeding exclusively at six weeks postpartum (Paper III). When pregnant women thought about their future breastfeeding, they were balancing between social norms and personal desires (Paper IV).

    These results can help to develop clinical practice to improve women’s experience of the first breastfeeding session. Additionally, the results may facilitate identifying women in need for targeted support, in order to promote longer exclusive breastfeeding duration. By acknowledging pregnant women’s thoughts and attitudes about breastfeeding, breastfeeding information and support, health care professionals can meet the needs and desires of women.

    Abstract [en]

    Objective: The aim of this study was to investigate the prevalence of healthcare professionals' use of the hands-on approach during the first breastfeeding session postpartum and its possible association with the mothers' experience of their first breastfeeding session. Materials and Methods: This was a population-based longitudinal study conducted at Uppsala University Hospital, Uppsala, Sweden, of all women giving birth at the hospital from May 2006 to June 2007. Six months postpartum, a questionnaire including questions regarding breastfeeding support, caregiving routines, depressive symptoms, and the woman's experience of the first breastfeeding session was sent to the mothers. The main outcome measures were use of the hands-on approach during the first breastfeeding session and the mother's experience of the breastfeeding session. Results: In total, 879 women participated in the study. Thirty-eight percent of the women received the hands-on approach during the first breastfeeding session. High body mass index, primiparity, and having the first breastfeeding session postponed were all independently associated with the hands-on approach. Women who received the hands-on approach were more likely to report a negative experience of the first breastfeeding session (odds ratio = 4.48; 95% confidence interval, 2.57-7.82), even after adjustment for possible confounders (odds ratio = 2.37; 95% confidence interval, 1.02-5.50). Conclusions: This study indicates that the hands-on approach is commonly used during the first breastfeeding session and is associated with a more negative experience of the first breastfeeding session. Consequently, caregivers need to question the use of this method, and further research about breastfeeding support is required.

    Abstract [en]

    Background: Breastfeeding rates in Sweden are declining, and it is important to identify women at risk for early cessation of exclusive breastfeeding.

    Objective: The aim of this study was to investigate factors associated with exclusive breastfeeding lasting less than two months postpartum.

    Methods: A population-based longitudinal study was conducted at Uppsala University Hospital, Sweden. Six hundred and seventy-nine women were included in this sub-study. Questionnaires were sent at five days, six weeks and six months postpartum, including questions on breastfeeding initiation and duration as well as several other background variables. The main outcome measure was exclusive breastfeeding lasting less than two months postpartum. Multivariable logistic regression analysis was used in order to calculate adjusted Odds Ratios (AOR) and 95% Confidence Intervals (95% CI).

    Results: Seventy-seven percent of the women reported exclusive breastfeeding at two months postpartum. The following variables in the multivariate regression analysis were independently associated with exclusive breastfeeding lasting less than two months postpartum: being a first time mother (AOR 2.15, 95% CI 1.32 +/- 3.49), reporting emotional distress during pregnancy (AOR 2.21, 95% CI 1.35 +/- 3.62) and giving birth by cesarean section (AOR 2.63, 95% CI 1.34 +/- 5.17).

    Conclusions: Factors associated with shorter exclusive breastfeeding duration were determined. Identification of women experiencing emotional distress during pregnancy, as well as scrutiny of caregiving routines on cesarean section need to be addressed, in order to give individual targeted breastfeeding support and promote longer breastfeeding duration.

    Holographic Wilson Loops: Quantum String Corrections2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The gauge-string duality has been one of the most exciting areas in theoretical physics as it connects strongly coupled field theories with weakly interacting strings. The present thesis concerns the study of Wilson loops in this correspondence. Wilson loops are observables arising in many physical situations like the propagation of particles in gauge fields, the problem of confinement, etc. In the gauge-string correspondence these observables have a known physical description at both sides, making them ideal probes for the duality. Remarkable progress from localization has lead to predictions at all orders in the coupling for certain Wilson loop configurations in supersymmetric field theories. Being the string theory weakly interacting, in principle we can use perturbation theory to calculate the corresponding quantities. However, current string calculations have only been successful at leading order and in rare cases, next to leading order. At next to leading order the difficulties encountered include divergences, ambiguous boundary conditions, mismatch with field theory results, etc. The research presented in this thesis aims at a better understanding of these issues. The first calculation presented here concerns the Wilson line in N=2*, a massive deformation of N=4 SYM. The string theory dual to this configuration is a straight line in the type IIB Pilch-Warner background. Using techniques for functional determinants, we computed the 1-loop string partition function obtaining perfect matching with localization. This constitutes a first test of the correspondence at the quantum level for nonconformal theories. The second calculation in this thesis corresponds to the ratio of the latitude and circular Wilson loops in AdS5xS5. An IR anomaly related to the singular nature of the conformal gauge is shown to solve previously found discrepancies with field theory results.

    We study string quantum corrections to the ratio of latitude and circular Wilson loops in N = 4 super-Yang-Mills theory at strong coupling. Conformal gauge for the corresponding minimal surface in AdS(5) x S-5 is singular and we show that an IR anomaly associated with the divergence in the conformal factor removes previously reported discrepancy with the exact field -theory result. We also carefully check conformal anomaly cancellation and recalculate fluctuation determinants by directly evaluting phaseshifts for all the fluctuation modes.

    A Novel Neural Network Model for Blood Pressure Estimation Using Photoplethesmography without Electrocardiogram2018In: Journal of Healthcare Engineering, ISSN 2040-2295, E-ISSN 2040-2309, article id 7804243Article in journal (Refereed)
    Abstract [en]

    The prevention, evaluation, and treatment of hypertension have attracted increasing attention in recent years. As photoplethysmography (PPG) technology has been widely applied to wearable sensors, the noninvasive estimation of blood pressure (BP) using the PPG method has received considerable interest. In this paper, a method for estimating systolic and diastolic BP based only on a PPG signal is developed. The multitaper method (MTM) is used for feature extraction, and an artificial neural network (ANN) is used for estimation. Compared with previous approaches, the proposed method obtains better accuracy; the mean absolute error is 4.02 +/- 2.79mmHg for systolic BP and 2.27 +/- 1.82mmHg for diastolic BP.

    Probing Magnetism at the Atomic Scale:  Non-Equilibrium Statistical Mechanics Theoretical Treatise2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Here, I present a theoretical study, based on non-equilibrium quantum statistical mechanics and on the non-equilibrium extension to the RKKY intveraction,where I investigate the emergence of magnetism at the atomic scale in adsorbed molecular complexes hosting localized spin moments, at the stake of being probed with scanning tunneling microscopy tip, and being driven by a temperature gradient and gated by an electric field. The scanning tunneling microscopy set up is modeled as a molecular junction with a magnetic molecule embedded within it, where the molecule consists in a set of electronic levels resembling the typical s-p orbitals of a metal hydride or an organometal, and a localized spin moment resembling the magnetic unit hosted by the latter and former type of molecules mentioned. The electronic levels and the magnetic units are coupled via the Kondo interaction. One of the electrodes in the junction plays the role of an scanning tunneling microscopy tip, and the other one, does it for the metal in which the molecule is adsorbed, and a bias voltage and a temperature gradient is applied across both metals, giving rise to the effect of the above mentioned experimental set up and producing electrical, spin, energy and heat currents as a response, providing the possibility to predict experimentally observed quantities such as differential conductivities. Throughout the thesis, I present first a comprehensive introduction to the topic pointing out its relevance, the experimental context in which the work I append lies and I as well present the formal structure of the work I present. The upcoming chapters, lead the audience to the discussion of the non-equilibrium formalism in atomic, molecular and condensed matter physics, paying special attention on the subject on magnetism, and putting in to context the molecular system where the interplay, among electrons, spins and phonons is relevant. To wrap up the theoretical discussion I described the state of the art progress on quantum coherence and interferometry in molecular junctions and locate my contribution into this context. Then I conclude and summarize. My contribution promises to pave the way to more robust spin based quantum engineered technology.

    Abstract [en]

    We consider charge and thermal transport properties of magnetically active paramagnetic molecular dimer. Generic properties for both transport quantities are reduced currents in. the ferro- and antiferromagnetic regimes compared to the paramagnetic and efficient Current blockade in the antiferromagnetic regime. In contrast, while the charge current is about an order of magnitude larger in the ferromagnetic regime, compared to the antiferromagnetic, the thermal current is efficiently blockaded there as well. This disparate behavior of the thermal current is attributed to current resonances in the ferromagnetic regime, which counteract the thermal flow. The temperature difference strongly reduces the exchange interaction and tends to destroy the magnetic control of the transport properties. The weakened exchange interaction opens up a possibility to tune the system into thermal rectification, for both the charge and thermal currents.

    (English)Manuscript (preprint) (Other academic)
    Abstract [en]

    We address the electronically induced anisotropy field acting on a spin moment comprised in a vibratingmagnetic molecule located in the junction between ferromagnetic metals. Under weak coupling between theelectrons and molecular vibrations, the nature of the anisotropy can be changed from favoring a high spin (easyaxis) magnetic moment to a low spin (easy plane) by applying a temperature difference or a voltage bias acrossthe junction. For unequal spin-polarizations in the ferromagnetic metals it is shown that the character of theanisotropy is essentially determined by the properties of the weaker ferromagnet. By increasing the temperaturein this metal, or introducing a voltage bias, its influence can be suppressed such that the dominant contributionto the anisotropy is interchanged to the stronger ferromagnet. With increasing coupling strength between themolecular vibrations and the electrons, the nature of the anisotropy is locked into favoring easy plane magnetis

    (English)Manuscript (preprint) (Other academic)
    Abstract [en]

    Novel understanding of the recent nanomagnet tailoring experiments and the possibility to further unveil the mechanisms by which the magnetic interactions arise in an atom by atom fashion covers importance as the demand for spin qubit and quantum state detection architectures increases. In the present letter, we address three spin states in triple quantum dots embedded in metallic tunneling junctions and show that the atom by atom magnetic interaction can be engineer through the electronic structure of the triple quantum dot, despite of not interacting among each other directly. We show that a bias and a gate voltage induces either a complete ferromagnetic state in the magnetic ion or a spin frustrated state with different stabilities, and switching among this states is possible on demand by electrical control. The role of quantum coherence in the triple dot is discussed with regards to the spin ordering as well as the interplay among electronic interference and induced dephasing by the metallic leads. This work sets foundations for more robust all electrically controlled spin architectures usable in quantum engineering systems and serves as a test bench for exploring unresolved questions in magnetic ordering and symmetry.

    We investigate spin-dependent thermoelectric signatures in a single-molecule magnet under the effect of timedependent external forces in the transient regime. We see a clear signature of the spin dynamics of the singlemolecule magnet due to the spin-dependent Peltier effect. Our results show further insight in spin-dependentthermoelectric phenomenon with time-dependent control.

    Assessing universality of DNA barcoding in geographically isolated selected desert medicinal species of Fabaceae and Poaceae2018In: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359, Vol. 6, article id e4499Article in journal (Refereed)
    Abstract [en]

    In pursuit of developing fast and accurate species-level molecular identification methods, we tested six DNA barcodes, namely ITS2, matK, rbcLa, ITS2+matK, ITS2+rbcLa, matK-krbcLa and ITS2+matK+rbcLa, for their capacity to identify frequently consumed but geographically isolated medicinal species of Fabaceae and Poaceae indigenous to the desert of Cholistan. Data were analysed by BLASTn sequence similarity, pairwise sequence divergence in TAXONDNA, and phylogenetic (neighbour-joining and maximum-likelihood trees) methods. Comparison of six barcode regions showed that ITS2 has the highest number of variable sites (209/360) for tested Fabaceae and (106/365) Poaceae species, the highest species-level identification (40%) in BLASTn procedure, distinct DNA barcoding gap, 100% correct species identification in BM and BCM functions of TAXONDNA, and clear cladding pattern with high nodal support in phylogenetic trees in both families. ITS2H-matK+rbcLa followed ITS2 in its species-level identification capacity. The study was concluded with advocating the DNA barcoding as an effective tool for species identification and ITS2 as the best barcode region in identifying medicinal species of Fabaceae and Poaceae. Current research has practical implementation potential in the fields of pharmacovigilance, trade of medicinal plants and biodiversity conservation.

    Wing bone geometry reveals active flight in Archaeopteryx2018In: Nature Communications, ISSN 2041-1723, E-ISSN 2041-1723, Vol. 9, article id 923Article in journal (Refereed)
    Abstract [en]

    Archaeopteryx is an iconic fossil taxon with feathered wings from the Late Jurassic of Germany that occupies a crucial position for understanding the early evolution of avian flight. After over 150 years of study, its mosaic anatomy unifying characters of both non-flying dinosaurs and flying birds has remained challenging to interpret in a locomotory context. Here, we compare new data from three Archaeopteryx specimens obtained through phase-contrast synchrotron microtomography to a representative sample of archosaurs employing a diverse array of locomotory strategies. Our analyses reveal that the architecture of Archaeopteryx's wing bones consistently exhibits a combination of cross-sectional geometric properties uniquely shared with volant birds, particularly those occasionally utilising short-distance flapping. We therefore interpret that Archaeopteryx actively employed wing flapping to take to the air through a more anterodorsally posteroventrally oriented flight stroke than used by modern birds. This unexpected outcome implies that avian powered flight must have originated before the latest Jurassic.

    Role of a single noncoding nucleotide in the evolution of an epidemic African clade of Salmonella2018In: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 115, no 11, p. E2614-E2623Article in journal (Refereed)
    Abstract [en]

    Salmonella enterica serovar Typhimurium ST313 is a relatively newly emerged sequence type that is causing a devastating epidemic of bloodstream infections across sub-Saharan Africa. Analysis of hundreds of Salmonella genomes has revealed that ST313 is closely related to the ST19 group of S. Typhimurium that cause gastroenteritis across the world. The core genomes of ST313 and ST19 vary by only similar to 1,000 SNPs. We hypothesized that the phenotypic differences that distinguish African Salmonella from ST19 are caused by certain SNPs that directly modulate the transcription of virulence genes. Here we identified 3,597 transcriptional start sites of the ST313 strain D23580, and searched for a gene-expression signature linked to pathogenesis of Salmonella. We identified a SNP in the promoter of the pgtE gene that caused high expression of the PgtE virulence factor in African S. Typhimurium, increased the degradation of the factor B component of human complement, contributed to serum resistance, and modulated virulence in the chicken infection model. We propose that high levels of PgtE expression by African S. Typhimurium ST313 promote bacterial survival and dissemination during human infection. Our finding of a functional role for an extragenic SNP shows that approaches used to deduce the evolution of virulence in bacterial pathogens should include a focus on noncoding regions of the genome.

    Anomalous dimensions in the WF O(N) model with a monodromy line defect2018In: Journal of High Energy Physics (JHEP), ISSN 1126-6708, E-ISSN 1029-8479, no 3, article id 058Article in journal (Refereed)
    Abstract [en]

    Implications of inserting a conformal, monodromy line defect in three dimensional O(N) models are studied. We consider then the WF O(N) model, and study the two-point Green's function for bulk-local operators found from both the bulk-defect expansion and Feynman diagrams. This yields the anomalous dimensions for bulk-and defect-local primaries as well as one of the OPE coefficients as epsilon-expansions to the first loop order. As a check on our results, we study the (phi(k))(2)phi(j) operator both using the bulk-defect expansion as well as the equations of motion.

    Unveiling new interdependencies between significant DNA methylation sites, gene expression profiles and glioma patients survival2018In: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 8, article id 4390Article in journal (Refereed)
    Abstract [en]

    In order to find clinically useful prognostic markers for glioma patients' survival, we employed Monte Carlo Feature Selection and Interdependencies Discovery (MCFS-ID) algorithm on DNA methylation (HumanMethylation450 platform) and RNA-seq datasets from The Cancer Genome Atlas (TCGA) for 88 patients observed until death. The input features were ranked according to their importance in predicting patients' longer (400+ days) or shorter (<= 400 days) survival without prior classification of the patients. Interestingly, out of the 65 most important features found, 63 are methylation sites, and only two mRNAs. Moreover, 61 out of the 63 methylation sites are among those detected by the 450 k array technology, while being absent in the HumanMethylation27. The most important methylation feature (cg15072976) overlaps with the RE1 Silencing Transcription Factor (REST) binding site, and was confirmed to intersect with the REST binding motif in human U87 glioma cells. Six additional methylation sites from the top 63 overlap with REST sites. We found that the methylation status of the cg15072976 site affects transcription factor binding in U87 cells in gel shift assay. The cg15072976 methylation status discriminates <= 400 and 400+ patients in an independent dataset from TCGA and shows positive association with survival time as evidenced by Kaplan-Meier plots.

    Action Prediction Allows Hypothesis Testing via Internal Forward Models at 6 Months of Age2018In: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 9, article id 290Article in journal (Refereed)
    Abstract [en]

    We propose that action prediction provides a cornerstone in a learning process known as internal forward models. According to this suggestion infants' predictions (looking to the mouth of someone moving a spoon upward) will moments later be validated or proven false (spoon was in fact directed toward a bowl), information that is directly perceived as the distance between the predicted and actual goal. Using an individual difference approach we demonstrate that action prediction correlates with the tendency to react with surprise when social interactions are not acted out as expected (action evaluation). This association is demonstrated across tasks and in a large sample (n = 118) at 6 months of age. These results provide the first indication that infants might rely on internal forward models to structure their social world. Additional analysis, consistent with prior work and assumptions from embodied cognition, demonstrates that the latency of infants' action predictions correlate with the infant's own manual proficiency.

    Production and sequential decay of charmed hyperons2018In: Physical Review D: covering particles, fields, gravitation, and cosmology, ISSN 2470-0010, E-ISSN 2470-0029, Vol. 97, no 5, article id 053002Article in journal (Refereed)
    Abstract [en]

    We investigate production and decay of the Lambda(+)(c) thornc hyperon. The production considered is through the e(+)e(-) annihilation channel, e(+)e(-) -> Lambda(+)(c)(Lambda) over bar (-)(c), with summation over the (Lambda) over bar (-)(c) antihyperon spin directions. It is in this situation that the Lambda(+)(c) decay chain is identified. Two kinds of sequential decays are studied. The first one is the doubly weak decay B-1 -> B2M2, followed by B-2 -> B3M3. The other one is the mixed weak-electromagnetic decay B-1 -> B2M2, followed by B-2 -> B-3 gamma. In both schemes B denotes baryons and M mesons. We should also mention that the initial state of the Lambda(+)(c) thornc hyperon is polarized.

    The Conundrum of Home-country Political Embeddedness: Impact on Reverse Knowledge Transfer in Emerging-market Multinationals2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Emerging-market multinational corporations (EMNCs), particularly state-owned ones, have been increasingly active players in the global arena and have become a significant feature of the global business landscape. Research on EMNCs has focused on their distinctive features, particularly on their politically embedded nature in home institutions. Another important feature in this field is the aim of knowledge-related asset augmentation overseas via strategic asset-seeking investments, conceptualized as a springboard perspective. In this vein, reverse knowledge transfer from subsidiaries to home-country organizations becomes critically significant in order for EMNCs to achieve the innovation catch-up. In response to the rise of EMNCs, this thesis focuses on the two above-mentioned core features of EMNCs by looking specifically at the impact of the home-country political embeddedness of EMNCs on reverse knowledge transfer. 

    The empirical investigation uses a sequential mixed-method approach that is comprised of qualitative research via a single case study of one Chinese state-owned multinational and quantitative research via a survey of 99 Chinese multinationals and their 177 overseas subsidiaries. The findings, based on empirical data, show, on one hand, that headquarters’ strong political embeddedness triggers strong intentions to seek and acquire knowledge from subsidiaries, particularly in advanced markets, through aligning with government objectives or shaping organizational distance between headquarters and subsidiaries. On the other hand, headquarters’ strong political embeddedness hampers reverse knowledge transfer practices in EMNCs by engendering a number of organizational barriers, including a low level of headquarters’ absorptive capacity, inferior performance of headquarters’ entrepreneurial role, less willingness of subsidiaries to transfer knowledge, and larger organizational distance between headquarters and subsidiaries. Consequently, headquarters’ political embeddedness acts as both a driver and a barrier to reverse knowledge transfer, which creates a paradox. This finding contrasts with those of most prior studies, where political relations were found to be a source of competitive advantage for international expansion.

    By stressing the importance of home-country political embeddedness in reverse knowledge transfer, this thesis extends the literature on the subject and advances the conceptualizations of the differentiated network multinationals and the embedded multinationals, which have focused almost exclusively on subsidiary embeddedness and ignored headquarters’ embeddedness in a home context. The present thesis also contributes to the literature on the parenting role of headquarters by providing evidence in support of a pessimistic view of headquarters’ parenting advantage and identifying political embeddedness as an important element that contributes to the value-creating/destroying role of headquarters in the EMNC context.

    Abstract [en]

    This article focuses on emerging-market multinationals and their intent to source knowledge from advanced countries. A single in-depth case study of a Chinese state-owned multinational is used to shed light on the relationship between political embeddedness and the potential to reverse knowledge transfer from advanced market subsidiaries. Specifically, we argue that a strong home-country political embeddedness enhances specific organizational barriers to reverse knowledge transfer, which undermines the strategic intent of knowledge-seeking internationalization, common to much Foreign Direct Investment (FDI) by emerging-market multinationals in recent years. This article contributes to research on knowledge sourcing within the context of south-north FDI by highlighting specific effects of political embeddedness at organizational level, which are critical for the possibilities to reverse knowledge transfer; our study is also relevant to international business, as new empirical insights related to the international organization and management of state-owned multinationals are discussed.

    Location: Uppsala University Level: Bachelor thesis in Media and Communication Studies

    Number of pages: 56

    Method: The method used in this thesis is a qualitative interview study.

    Title: Affect your reputation! A qualitative study on how Swedish companies in the food

    industry try to influence their reputation through their specific communication on social media.

    Aim: The overall aim with this study is to understand how organizations in the food industry

    try to influence their reputation through communication on social media.

    Theories: The theoretical perspective of the study is organizational reputation and reputation

    on social media.

    Main results: The result from the interview study shows that organizations in the food industry

    are not communicating in the same way, contrariwise there are some common factors between

    the organizations in their way of influencing the reputation. The common factors are measured

    through the temperature on the separate organization’s users through media sourcing,

    communicating in a transparent and credible way and responding quickly to users. Furthermore,

    the result shows that each organisation find its own way of communicating on social media to

    influence their reputation on social media in their daily communication work.

    Facilitated sequence assembly using densely labeled optical DNA barcodes: A combinatorial auction approach2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 3, article id e0193900Article in journal (Refereed)
    Abstract [en]

    The output from whole genome sequencing is a set of contigs, i.e. short non-overlapping DNA sequences (sizes 1-100 kilobasepairs). Piecing the contigs together is an especially difficult task for previously unsequenced DNA, and may not be feasible due to factors such as the lack of sufficient coverage or larger repetitive regions which generate gaps in the final sequence. Here we propose a new method for scaffolding such contigs. The proposed method uses densely labeled optical DNA barcodes from competitive binding experiments as scaffolds. On these scaffolds we position theoretical barcodes which are calculated from the contig sequences. This allows us to construct longer DNA sequences from the contig sequences. This proof-of-principle study extends previous studies which use sparsely labeled DNA barcodes for scaffolding purposes. Our method applies a probabilistic approach that allows us to discard "foreign" contigs from mixed samples with contigs from different types of DNA. We satisfy the contig non-overlap constraint by formulating the contig placement challenge as a combinatorial auction problem. Our exact algorithm for solving this problem reduces computational costs compared to previous methods in the combinatorial auction field. We demonstrate the usefulness of the proposed scaffolding method both for synthetic contigs and for contigs obtained using Illumina sequencing for a mixed sample with plasmid and chromosomal DNA.

    Abstract [en]

    This master thesis is an investigation of environmentalsustainability of photovoltaic (PV) modules. The purpose is toexamine how purchasers of PV systems could put requirements on themodules so that their life-cycle carbon dioxide emissions reduces inthe most effective way. The purpose is also to survey environmentalthird-party certifications for solar modules. Only mono- and multicrystallinesilicon modules are considered. In the first part of thethesis, the carbon dioxide emissions from the manufacturing andtransportation of different modules are calculated. Furthermore, thesolar electricity production is simulated in the software PVsyst. Modules with different peak power capacity, origins and manufacturedwith different techniques are compared. In part two, recyclingtechniques and regulations for management of end-of-life-modules areinvestigated. The number of end-of-life modules based on Solkompaniet Sverige AB´s historical installations are estimated and out of these, their potential economic value, based on two different recyclingscenarios, is calculated.

    According to the results, monocrystalline modules cause higheremissions than equivalent multi-crystalline from the samemanufacturer. Modules with the same peak power and silicon but withdifferent origins and silicon manufactured with differenttechnologies, produce about the same amount of electricity, but showa large variation in carbon dioxide emissions, mainly due theelectricity consumption and the characteristics of the electrical mixused in the manufacturing process. The modules’ operating time inaddition to prerequisite conditions for mounting are crucial for theemissions per produced kWh electricity, contrary the transports havevery little effect on the total emissions. Carbon dioxide emissionscould be reduced through re-usage of elements from recycled end-oflifemodules, particularly aluminum and silicon, but economic factorshinder this today, mainly due to too few end-of-life modules. Silveris the most expensive element in a module. The value of end-of-lifemodules will decrease by decreasing silver content, but overallincrease due to increased waste volumes. The future economic value ofend-of-life modules is hard to estimate, but could be crucial for thepossibility to take advantage of the environmental benefit fromtreatment of end-of-life modules.

    In order to reduce carbon dioxide emissions from solar modules,requirements should be directed towards the module manufacturingprocess. This thesis emphasizes prerequisites expected to give loweremissions, hence modules that are more likely to cause lowerenvironmental impact than others. To be able to develop specificrequirements, more transparent and reliable energy consumption datais necessary. It exists very few, and no Swedish environmentalcertifications specifically designed for solar modules. The rankinglist Solar Scorecard is not a certification but seems to be the mostused in order to demonstrate manufacturers' environmentalperformances.

    Influence of Aromaticity on Excited State Structure, Reactivity and Properties2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis describes work that could help development of new photochemical reactions and light-absorbing materials. Focus is on the chemical concept "aromaticity" which is a proven conceptual tool in developing thermal chemical reactions. It is here shown that aromaticity is also valuable for photochemistry. The influence of aromaticity is discussed in terms of structure, reactivity and properties. With regard to structure, it is found that photoexcited molecules change their structure to attain aromatic stabilization (planarize, allow through-space conjugation) or avoid antiaromatic destabilization (pucker). As for reactivity, it is found that stabilization/destabilization of reactants decrease/increase photoreactivity, in accordance with the Bell-Evans-Polanyi relationship. Two photoreactions based on excited state antiaromatic destabilization of the substrates are reported. Finally, with respect to properties, it is shown that excited state energies can be tuned by considering aromatic effects of both the electronic ground state and the electronically excited states. The fundamental research presented in this thesis forms a foundation for the development of new photochemical reactions and design of compounds for new organic electronic materials.

    Summary

    The concept of excited-state aromaticity is receiving much attention in that completely reversed aromaticity in the excited state (so-called aromaticity reversal) provides crucial insight into photostability, photoreactivity, and its application to the photosynthetic mechanism and photoactive materials. Despite this significance, experimental elucidation of excited-state aromaticity is still unsolved, particularly for the excited singlet state. Here, as an unconventional approach, time-resolved IR (TRIR) spectroscopy on aromatic and anti-aromatic hexaphyrin congeners shed light on excited-singlet-state aromaticity. The contrasting spectral features between the Fourier transform IR and TRIR spectra reveal the aromaticity-driven structural changes, corroborating aromaticity reversal in the excited singlet states. Our paradigm for excited-state aromaticity, the correlation of IR spectral features with aromaticity reversal, provides another fundamental key to understanding the role of (anti)aromaticity in the stability, dynamics, and reactivity in the excited singlet state of π-conjugated molecular systems.

    Abstract [en]

    Cyclic conjugation that occurs through-space and leads to aromatic properties is called homoaromaticity. Here we formulate the homoaromaticity concept for the triplet excited state (T1) based on Baird's 4n rule and validate it through extensive quantum-chemical calculations on a range of different species (neutral, cationic and anionic). By comparison to well-known ground state homoaromatic molecules we reveal that five of the investigated compounds show strong T1 homoaromaticity, four show weak homoaromaticity and two are non-aromatic. Two of the compounds have previously been identified as excited state intermediates in photochemical reactions and our calculations indicate that they are also homoaromatic in the first singlet excited state. Homoaromaticity should therefore have broad implications in photochemistry. We further demonstrate this by computational design of a photomechanical “lever” that is powered by relief of homoantiaromatic destabilization in the first singlet excited state.

    Abstract [en]

    For the concept of aromaticity, energetic quantification is crucial. However, this has been elusive for excited-state (Baird) aromaticity. Here we report our serendipitous discovery of two nonplanar thiophene-fused chiral [4n]annulenes Th4COT Saddle and Th6CDH Screw, which by computational analysis turned out to be a pair of molecules suitable for energetic quantification of Baird aromaticity. Their enantiomers were separable chromatographically but racemized thermally, enabling investigation of the ring inversion kinetics. In contrast to Th6CDH Screw, which inverts through a nonplanar transition state, the inversion of Th4COT Saddle, progressing through a planar transition state, was remarkably accelerated upon photoexcitation. As predicted by Baird’s theory, the planar conformation of Th4COT Saddle is stabilized in the photoexcited state, thereby enabling lower activation enthalpy than that in the ground state. The lowering of the activation enthalpy, i.e., the energetic impact of excited-state aromaticity, was quantified experimentally to be as high as 21–22 kcal mol–1.

    Abstract [en]

    The cyclopropyl (cPr) group, which is a well-known probe for detecting radical character at atoms to which it is connected, is tested as an indicator for aromaticity in the first * triplet and singlet excited states (T-1 and S-1). Baird's rule says that the -electron counts for aromaticity and antiaromaticity in the T-1 and S-1 states are opposite to Huckel's rule in the ground state (S-0). Our hypothesis is that the cPr group, as a result of Baird's rule, will remain closed when attached to an excited-state aromatic ring, enabling it to be used as an indicator to distinguish excited-state aromatic rings from excited-state antiaromatic and nonaromatic rings. Quantum chemical calculations and photoreactivity experiments support our hypothesis; calculated aromaticity indices reveal that openings of cPr substituents on [4n]annulenes ruin the excited-state aromaticity in energetically unfavorable processes. Yet, polycyclic compounds influenced by excited-state aromaticity (e.g., biphenylene), as well as 4n-electron heterocycles with two or more heteroatoms represent limitations.

    Abstract [en]

    Baird's rule tells that the electron counts for aromaticity and antiaromaticity in the first pi pi* triplet and singlet excited states (T-1 and S-1) are opposite to those in the ground state (S-0). Our hypothesis is that a silacyclobutene (SCB) ring fused with a [4n]annulene will remain closed in the T-1 state so as to retain T-1 aromaticity of the annulene while it will ring-open when fused to a [4n + 2]annulene in order to alleviate T-1 antiaromaticity. This feature should allow the SCB ring to function as an indicator for triplet state aromaticity. Quantum chemical calculations of energy and (anti)aromaticity changes along the reaction paths in the T-1 state support our hypothesis. The SCB ring should indicate T-1 aromaticity of [4n]annulenes by being photoinert except when fused to cyclobutadiene, where it ring-opens due to ring-strain relief.

    Abstract [en]

    The last missing example of the four archetypical cycloaromatizations of enediynes and enynes was discovered by combining a twisted alkene excited state with a new self-terminating path for intramolecular conversion of diradicals into closed-shell products. Photoexcitation of aromatic enynes to a twisted alkene triplet state creates a unique stereoelectronic situation, which is facilitated by the relief of excited state antiaromaticity of the benzene ring. This enables the usually unfavorable 5-endo-trig cyclization and merges it with 5-exo-dig closure. The 1,4-diradical product of the C1-C5 cyclization undergoes internal H atom transfer that is coupled with the fragmentation of an exocyclic C-C bond. This sequence provides efficient access to benzofulvenes from enynes and expands the utility of self-terminating aromatizing enyne cascades to photochemical reactions. The key feature of this self-terminating reaction is that, despite the involvement of radical species in the key cyclization step, no external radical sources or quenchers are needed to provide the products. In these cascades, both radical centers are formed transiently and converted to the closed-shell products via intramolecular H-transfer and C-C bond fragmentation. Furthermore, incorporating C-C bond cleavage into the photochemical self-terminating cyclizations of enynes opens a new way for the use of alkenes as alkyne equivalents in organic synthesis.

    Abstract [en]

    The first hydrogenation step of benzene, which is endergonic in the electronic ground state (S0), becomes exergonic in the first triplet state (T1). This is in line with Baird’s rule, which tells that benzene is antiaromatic and destabilized in its T1 state and also in its first singlet excited state (S1), opposite to S0, where it is aromatic and remarkably unreactive. Here we utilized this feature to show that benzene and several polycyclic aromatic hydrocarbons (PAHs) to various extents undergo metal-free photochemical (hydro)silylations and transfer-hydrogenations at mild conditions, with the highest yield for naphthalene (photosilylation: 21%). Quantum chemical computations reveal that T1-state benzene is excellent at H-atom abstraction, while COT, aromatic in the T1 and S1 states according to Baird’s rule, is unreactive. Remarkably, also CVD-graphene on SiO2 is efficiently transfer-photohydrogenated using formic acid/water mixtures together with white light or solar irradiation under metal-free conditions.

    Abstract [en]

    A new qualitative model for estimating the properties of substituted cyclopentadienes and siloles in their lowest pi pi* excited states is introduced and confirmed through quantum chemical calculations, and then applied to explain earlier reported experimental excitation energies. According to our model, which is based on excited-state aromaticity and antiaromaticity, siloles and cyclopentadienes are cross-hyperconjugated "aromatic chameleons" that adapt their electronic structures to conform to the various aromaticity rules in different electronic states (Huckel's rule in the pi(2) electronic ground state (S-0) and Baird's rule in the lowest pi pi* excited singlet and triplet states (S-1 and T-1)). By using pen-and-paper arguments, one can explain polarity changes upon excitation of substituted cyclopentadienes and siloles, and one can tune their lowest excitation energies by combined considerations of ground-and excited-state aromaticity/antiaromaticity effects. Finally, the "aromatic chameleon" model can be extended to other monocyclic compound classes of potential use in organic electronics, thereby providing a unified view of the S-0, T-1, and S-1 states of a range of different cyclic cross-pi-conjugated and cross-hyperconjugated compound classes.

    Abstract [en]

    The low-lying triplet state of a recently published compound (TMTQ) was analyzed quantum chemically in light of suggestions that it is influenced by Baird aromaticity. Two mesomeric structures describe this state: 1)a zwitterionic Baird aromatic structure with a triplet diradical 8-electron methano[10]annulene (M10A) dicationic ring and 2)a Huckel aromatic with a neutral closed-shell 10-electron ring. According to charge and spin density distributions, the Huckel aromatic structure dominates the triplet state (the Baird aromatic contributes at most 12%), and separation of the aromatic fluctuation index (FLU) into and electron contributions emphasizes this finding. The small singlet-triplet energy gap is due to Huckel aromaticity of the M10A ring, clarified by comparison to the smaller analogues of TMTQ. Yet, TMTQ and its analogues are Huckel-Baird hybrids allowing for tuning between closed-shell 4n+2 Huckel aromaticity and open-shell 4n Baird aromaticity.
