    M2 macrophages and regulatory T cells in lethal prostate cancer2018Inngår i: The Prostate, ISSN 0270-4137, E-ISSN 1097-0045Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Prostate cancer (PCa) is one of the most frequently diagnosed cancers in the world. Emerging evidence suggests that inflammatory cells such as M2 macrophages and regulatory T cells (Tregs) can contribute to cancer progression by suppressing the anti‐tumor immune response. This study investigated the number of CD163‐positive M2 macrophages in PCa tissue. It also investigated the correlation and interaction of M2 macrophages and Tregs.

    Methods: This nested case‐control study included subjects from a cohort of men diagnosed with PCa as an incidental finding during transurethral resection of the prostate. The cases were 225 men who died from PCa, and the controls were 367 men who survived more than 10 years after PCa diagnosis without disease progression. Infiltrating CD163‐positive M2 macrophages and FOXP3/CD4‐positive Tregs in PCa tissue were identified using immunohistochemistry. The correlation and interaction of M2 macrophages and Tregs were assessed using Spearman's rank‐order correlation and a likelihood test, respectively. Logistic regression was used to estimate odds ratios (ORs) for lethal PCa and macrophage counts.

    Results: The number of M2 macrophages and Tregs showed a significant correlation (P < 0.001) but no interactions. The OR for lethal PCa was 1.93 (95%CI: 1.23‐3.03) for men with high numbers of M2 macrophages. Also for cases with uncertain outcome (GS categories 3 + 4 and 4 + 3) high numbers of M2 macrophages does predict a poorer prognosis.

    Conclusions: Our data showed that men with high numbers of M2 macrophages in the prostate tumor environment had increased odds of dying of PCa. It is possible that M2 macrophages, together with other suppressor cells such as Tregs, promote an immunosuppressive environment.

    A bacterial genotoxin causes virus reactivation and genomic instability in Epstein-Barr virus infected epithelial cells pointing to a role of co-infection in viral oncogenesis2019Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 144, nr 1, s. 98-109Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We have addressed the role of bacterial co-infection in viral oncogenesis using as model Epstein-Barr virus (EBV), a human herpesvirus that causes lymphoid malignancies and epithelial cancers. Infection of EBV carrying epithelial cells with the common oral pathogenic Gram-negative bacterium Aggregatibacter actinomycetemcomitans (Aa) triggered reactivation of the productive virus cycle. Using isogenic Aa strains that differ in the production of the cytolethal distending toxin (CDT) and purified catalytically active or inactive toxin, we found that the CDT acts via induction of DNA double strand breaks and activation of the Ataxia Telangectasia Mutated (ATM) kinase. Exposure of EBV-negative epithelial cells to the virus in the presence of sub-lethal doses of CDT was accompanied by the accumulation of latently infected cells exhibiting multiple signs of genomic instability. These findings illustrate a scenario where co-infection with certain bacterial species may favor the establishment of a microenvironment conducive to the EBV-induced malignant transformation of epithelial cells.

    Resource mobilization among informal entrepreneurs: A case of event planning industry of Pakistan2018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    This dissertation studies resource mobilization among informal entrepreneurs. It combines the resource mobilization perspective with insights from social capital and human capital theory to understand the resource mobilization activities of informal entrepreneurs, focusing on the founding period and the early years of existence of informal ventures. Empirically the study is based on 15 cases from event planning industry of Pakistan. It primarily uses semi-structured interviews along with observations and secondary documents. The within and cross-case coding are aggregated into a conceptual model that paves the way to understanding inter-organizational gains through informal entrepreneurial networks. These informal entrepreneurial networks are largely based on competitor’s networks that support the exchange of resources, such as the exchange of knowledge, raw material, ideas, opportunities, etc. The new insights contributed from the findings are that resource mobilization is not competitive but rather collaborative among informal entrepreneurs. This collaborative resource mobilization is mainly based on activities like competitor’s collaboration, collaborative knowledge sharing through informal venturing, for the advancement of business goals at founding and in later stages. Collaborative resource mobilization is an alternative to competitive resource mobilization, whereby the flow of resources in the networks remains competitive when it comes to business rivalry. The study contributes to the role of social and human capital in resource mobilizing activities that improve the synergistic effects contributing to the readiness of informal entrepreneurs. Trust and reciprocal exchange of resources among competitors act as a major strengthening factor in promoting collaborative resource mobilization among informal entrepreneurs. It also contributes to the informal entrepreneurship literature and suggests that informal entrepreneurship should not be considered as marginalized activities, but rather a platform where the considerable potential of creative entrepreneurial activity is present.

    Exposure to Outdoor Particles (PM2.5) and Associated Child Morbidity and Mortality in Socially Deprived Neighborhoods of Nairobi, Kenya2018Inngår i: Atmosphere, ISSN 2073-4433, E-ISSN 2073-4433, Vol. 9, nr 9, artikkel-id 351Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Exposure to air pollution is associated with adverse health outcomes. However, the health burden related to ambient outdoor air pollution in sub-Saharan Africa remains unclear. This study examined the relationship between exposure to outdoor air pollution and child health in urban slums of Nairobi, Kenya. We conducted a semi-ecological study among children under 5 years of age from two slum areas and exposure measurements of particulate matter (PM2.5) at the village level were aligned to data from a retrospective cohort study design. We used logistic and Poisson regression models to ascertain the associations between PM2.5 exposure level and child morbidity and mortality. Compared to those in low-pollution areas (PM2.5 < 25 µg/m3), children in high-pollution areas (PM2.5 ≥ 25 µg/m3) were at significantly higher risk for morbidity in general (odds ratio (OR) = 1.25, 95% confidence interval (CI): 1.11–1.41) and, specifically, cough (OR = 1.38, 95% CI: 1.20–1.48). Exposure to high levels of pollution was associated with a high child mortality rate from all causes (IRR = 1.22, 95% CI: 1.08–1.39) and respiratory causes (IRR = 1.12, 95% CI: 0.88–1.42). The findings indicate that there are associated adverse health outcomes with air pollution in urban slums. Further research on air pollution health impact assessments in similar urban areas is required.

    The global Food-Energy-Water Nexus2018Inngår i: Reviews of geophysics, ISSN 8755-1209, E-ISSN 1944-9208, Vol. 56, nr 3, s. 456-531Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Water availability is a major factor constraining humanity's ability to meet the future food and energy needs of a growing and increasingly affluent human population. Water plays an important role in the production of energy, including renewable energy sources and the extraction of unconventional fossil fuels that are expected to become important players in future energy security. The emergent competition for water between the food and energy systems is increasingly recognized in the concept of the "food-energy-water nexus." The nexus between food and water is made even more complex by the globalization of agriculture and rapid growth in food trade, which results in a massive virtual transfer of water among regions and plays an important role in the food and water security of some regions. This review explores multiple components of the food-energy-water nexus and highlights possible approaches that could be used to meet food and energy security with the limited renewable water resources of the planet. Despite clear tensions inherent in meeting the growing and changing demand for food and energy in the 21st century, the inherent linkages among food, water, and energy systems can offer an opportunity for synergistic strategies aimed at resilient food, water, and energy security, such as the circular economy.

    Household Preferences to Reduce Their Greenhouse Gas Footprint: A Comparative Study from Four European Cities2018Inngår i: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 10, nr 11, artikkel-id 4044Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper investigates households’ preferences to reduce their carbon footprint (CF) measured in carbon dioxide equivalents (CO2e). It assumes that a substantial CF reduction of households is essential to reach the 1.5 ◦C goal under the Paris Agreement. Data was collected in four mid-size cities in France, Germany, Norway, and Sweden. Quantitative data was obtained from 308 households using a CF calculator based on a questionnaire, and a simulation game. The latter investigated households’ preferences when being confronted with the objective to reduce their CF by 50 percent by 2030 in a voluntary and forced scenario. Our results show that the greater the CO2e-reduction potential of a mitigation action, the less willing a household was to implement that action. Households preferred actions with moderate lifestyle changes foremost in the food sector. Voluntarily, households reached a 25% footprint reduction by 2030. To reach a substantial reduction of 50 percent, households needed to choose actions that meant considerable lifestyle changes, mainly related to mobility. Given our results, the 1.5 ◦C goal is unlikely to be realizable currently, unless households receive major policy support. Lastly, the strikingly similar preferences of households in the four European cities investigated seem to justify strong EU and international policies.

    Mapping Systematic Reviews on Forensic Psychiatric Care: A Systematic Review Identifying Knowledge Gaps2018Inngår i: Frontiers in Psychiatry, ISSN 1664-0640, E-ISSN 1664-0640, Vol. 9, artikkel-id 452Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Background: Forensic psychiatric care treats mentally disordered offenders who suffer mainly from psychotic disorders, although comorbidities such as personality disorders, neurodevelopmental disorders, and substance abuse are common. A large proportion of these patients have committed violent crimes. Their care is involuntary, and their caregivers' mission is complex: not only to rehabilitate the patient, but also to consider their risk for reoffending and their risk to society. The objective of this overview of systematic reviews is to identify, appraise, and summarize the existing knowledge in forensic psychiatric care and identify knowledge gaps that require further research.

    Methods: We undertook a systematic literature search for systematic reviews in five defined domains considered important in daily clinical practice within the forensic psychiatric care: (1) diagnostic assessment and risk assessments; (2) pharmacological treatment; (3) psychological interventions; (4) psychosocial interventions, rehabilitation, and habilitation; and (5) restraint interventions. The target population was mentally disordered offenders (forensic psychiatric patients aged >15 years). Each abstract and full text review was assessed by two of the authors. Relevant reviews then were assessed for bias, and those with moderate or low risk of bias were included.

    Results: Of 38 systematic reviews meeting the inclusion criteria, only four had a moderate risk of bias. Two aimed to incorporate as many aspects of forensic psychiatric care as possible, one investigated non-pharmacological interventions to reduce aggression in forensic psychiatric care, and one focused on women with intellectual disabilities in forensic care. However, most of the primary studies included in these reviews had high risks of bias, and therefore, no conclusions could be drawn. All of our identified domains must be considered knowledge gaps.

    Conclusion: We could not answer any of our research questions within the five domains because of the high risk of bias in the primary studies in the included systematic reviews. There is an urgent need for more research on forensic psychiatric care since all of our studied domains were considered knowledge gaps.

    Potential benefits of triage for the trauma patient in a Kenyan emergency department2018Inngår i: BMC Emergency Medicine, ISSN 1471-227X, E-ISSN 1471-227X, Vol. 18, nr 49, s. 1-7Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background

    Improved trauma management can reduce the time between injury and medical interventions, thus decreasing morbidity and mortality. Triage at the emergency department is essential to ensure prioritization and timely assessment of injured patients. The aim of the present study was to investigate how a lack of formal triage system impacts timely intervention and mortality in a sub-Saharan referral hospital. Further, the study attempts to assess potential benefits of triage towards efficient management of trauma patients in one middle income country.

    Methods

    A prospective descriptive study was conducted. Adult trauma patients admitted to the emergency department during an 8-month period at Moi Teaching and Referral Hospital in Eldoret, Kenya, were included. Mode of arrival and vital parameters were registered. Variables included in the analysis were Injury Severity Score, time before physician’s assessment, length of hospital stay, and mortality. The patients were retrospectively categorized according to the Rapid Emergency Triage and Treatment System (RETTS) from patient records.

    Results

    A total of 571 patients were analyzed, with a mean Injury Severity Score of 12.2 (SD 7.7) with a mean length of stay of 11.6 (SD 18.3) days. The mortality rate was 1.8%. The results obtained in this study illustrate that trauma patients admitted to the emergency department at Eldoret are not assessed in a timely fashion, and the time frame recommendations postulated by RETTS are not adhered to. Assessment of patients according to the triage algorithm used revealed a significantly higher average Injury Severity Score in the red category than in the other color categories.

    Conclusion

    The results from this study clearly illustrate a lack of correct prioritization of patients in relation to the need for timely assessment. This is further demonstrated by the retrospective triage classification of patients, which identified patients with high ISS as in urgent need of care. Since no significant difference in to time to assessment regardless of injury severity was observed, the need for a well-functioning triage system is apparent.

    Technical assessment of energy storage systems for power system applications via suitability index approach (Part IV)Manuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Energy storage systems provide several benets and services in optimizing the power grid's reliability, effciency and safety. However, the feasibility of energy storage systems varies dependent on the requirements of the applications. Technical limitations in design and type of the storage technology prevents a single storage type to perform equally well in all situations. Hence,it is essential to compare and measure the energy storages' usefulness anddetermine their optimal use. To address this issue this study introduces an indexing approach to evaluate the suitability of energy storages for power system applications. Four different energy storages (double-layer capacitor, flywheel, lead-acid battery, lithium-ion battery) are tested for four typical energy storage applications (frequency regulation, voltage support, capacity firming and energy time-shift). The suitability index allows a simple and intuitive way to compare and rank the suitability of energy storages.

    Conceptualising creativity benefits of nature experience: Attention restoration and mind wandering as complementary processes2018Inngår i: Journal of Environmental Psychology, ISSN 0272-4944, E-ISSN 1522-9610, Vol. 59, s. 36-45Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Accumulating evidence indicates that time spent in natural environments promotes creativity, but few researchers have considered how this occurs. We evaluate two candidate mechanisms, attention restoration and mind wandering. We compare the accounts in terms of attentional focus, brain network activation, cognitive effects, and the temporal progression of these processes across the stages of creativity. Based on this analysis, we propose that (1) gentle shifts between externally oriented soft fascination and internally oriented mind wandering can occur during nature experience; (2) this provides the basis for mutually reinforcing pathways that enhance attention control following nature experience; and (3) mind wandering might support additional benefits for creativity, including flexibility and new associations of ideas. We propose research to test the proposed pathways, including the conditions under which environments influence creativity, the ebb and flow of attention orientation during environmental experience, and the links between attentional focus, brain network activation and creativity.

    Factores asociados a la respuesta a la violencia del compañero íntimo en atención primaria de salud en España2018Inngår i: Gaceta Sanitaria, ISSN 0213-9111, E-ISSN 1578-1283, Vol. 32, nr 5, s. 433-438Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [es]

    Objetivo: Analizar la capacidad de respuesta a la violencia del compañero íntimo (VCI) de profesionales sanitarios/as españoles/as en atención primaria e identificar posibles determinantes que puedan favorecer una mejor respuesta.

    Método: Estudio transversal con muestreo no probabilístico y por conveniencia en profesionales sanitarios/as de 15 centros de atención primaria españoles. El instrumento Physician Readiness to Manage Intimate Partner Violence Survey (PREMIS), en su versión validada y traducida al español, permitió recolectar información sobre conocimientos, opiniones y prácticas sobre VCI. Se realizaron análisis estadísticos descriptivo y de regresión lineal bivariada y multivariada.

    Resultados: Se recibieron 265 cuestionarios diligenciados, con una tasa de respuesta del 80,3%. Se observó un efecto exposición-respuesta, en el que a más horas de formación, mayor puntuación en las escalas del cuestionario (p <0,05). La edad, el tipo de profesión, los años de experiencia en atención primaria, las horas de formación en VCI y la lectura del protocolo mostraron asociación positiva con conocimientos (preparación percibida, conocimiento percibido, conocimiento real), opiniones (preparación del equipo, requerimientos legales, autoeficacia, disponibilidad de recursos en el lugar de trabajo, barreras, entendimiento de la víctima) y prácticas del personal sanitario.

    Conclusiones: Leer el protocolo de actuación regional/nacional y recibir formación en VCI fueron las intervenciones más importantes asociadas a una mejor capacidad de respuesta a la VCI de los/las profesionales sanitarios/as en atención primaria.

    Abstract [sv]

    I artikeln diskuteras handledningspraktiker vid universitet och högskolor i Sverige och i Finland ur ett jämförande perspektiv. Diskussionen bygger på de kommunikativa skillnader vi iakttagit mellan inspelningar av sverigesvenska och finlandssvenska handledningssamtal, bland annat vad gäller hur råd ges och tas emot, hur deltagarna hanterar den inneboende asymmetrin samt hur pronomen används under ett handledningssamtal. De empiriska observationerna av handledningspraktiker i autentiska handledningssamtal relateras till två svenskspråkiga högskolepedagogiska vägledningar för uppsatshandledning, en från Sverige och en från Finland. De kommunikativa skillnader vi noterat i de sverigesvenska och de finlandssvenska handledningssamtalen återspeglas i de två studerade handböckerna. Vad gäller såväl handledningssamtalen som handledningsmanualerna ser vi en större tendens till att tona ner asymmetrier och framhäva det kollektiva i de sverigesvenska handledningspraktikerna, medan de finlandssvenska handledningspraktikerna uppvisar en tydligare orientering mot individuellt ansvar och en mer oproblematisk inställning till de institutionella rollerna som handledare och student.

    Accessibility and factors associated with utilization of mental health services in youth health centers: a qualitative comparative analysis in northern Sweden2018Inngår i: International Journal of Mental Health Systems, ISSN 1752-4458, E-ISSN 1752-4458, Vol. 12, artikkel-id 69Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Youth-friendly health care services can facilitate young people's access to health care services and promote their health, including their mental health. In Sweden, a network of youth health centers exist since the 1970s, incorporated within the public health system. Even if such centers take a holistic approach to youth health, the focus has been in sexual and reproductive health care, and the extent of integrating mental health care services is less developed though it varies notably between different centers. This study aims to analyse the various conditions that are sufficient and/or necessary to make Swedish youth health centers accessible for mental and psychosocial health.

    Methods: Multiple case study design, using qualitative comparative analysis to assess the various conditions that makes a youth health center accessible for mental and psychosocial issues and mental health. The cases included 18 youth health centers (from a total of 22) in the four northern counties of Sweden.

    Results: In order to enhance accessibility for mental health services, youth health centers need to be trusted by young people. Trust was necessary but not sufficient, meaning that it had to be combined with other conditions: either having a team with a variety of professions represented in the youth health center, or being a youth health center that is both easy to contact and well-staffed with mental health professionals.

    Conclusions: Differentiated, first-line services for youth can play an important role in promoting youth mental health if certain conditions are fulfilled. Trust is necessary, but has to be combined with either multidisciplinary teams, or expertise on mental health and easy accessibility.

    Nutritional quality of food as represented by the FSAm-NPS nutrient profiling system underlying the Nutri-Score label and cancer risk in Europe: results from the EPIC prospective cohort study2018Inngår i: PLoS Medicine, ISSN 1549-1277, E-ISSN 1549-1676, Vol. 15, nr 9, artikkel-id e1002651Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background

    Helping consumers make healthier food choices is a key issue for the prevention of cancer and other diseases. In many countries, political authorities are considering the implementation of a simplified labelling system to reflect the nutritional quality of food products. The Nutri-Score, a five-colour nutrition label, is derived from the Nutrient Profiling System of the British Food Standards Agency (modified version) (FSAm-NPS). How the consumption of foods with high/low FSAm-NPS relates to cancer risk has been studied in national/regional cohorts but has not been characterized in diverse European populations.

    Methods and findings

    This prospective analysis included 471,495 adults from the European Prospective Investigation into Cancer and Nutrition (EPIC, 1992-2014, median follow-up: 15.3 y), among whom there were 49,794 incident cancer cases (main locations: breast, n = 12,063; prostate, n = 6,745; colon-rectum, n = 5,806). Usual food intakes were assessed with standardized country-specific diet assessment methods. The FSAm-NPS was calculated for each food/beverage using their 100-g content in energy, sugar, saturated fatty acid, sodium, fibres, proteins, and fruits/vegetables/legumes/nuts. The FSAm-NPS scores of all food items usually consumed by a participant were averaged to obtain the individual FSAm-NPS Dietary Index (DI) scores. Multi-adjusted Cox proportional hazards models were computed. A higher FSAm-NPS DI score, reflecting a lower nutritional quality of the food consumed, was associated with a higher risk of total cancer (HRQ5 versus (Q1) = 1.07; 95% CI 1.03-1.10, P-trend < 0.001). Absolute cancer rates in those with high and low (quintiles 5 and 1) FSAm-NPS DI scores were 81.4 and 69.5 cases/10,000 person-years, respectively. Higher FSAm-NPS DI scores were specifically associated with higher risks of cancers of the colon-rectum, upper aerodigestive tract and stomach, lung for men, and liver and postmenopausal breast for women (all P < 0.05). The main study limitation is that it was based on an observational cohort using self-reported dietary data obtained through a single baseline food frequency questionnaire; thus, exposure misclassification and residual confounding cannot be ruled out.

    Conclusions

    In this large multinational European cohort, the consumption of food products with a higher FSAm-NPS score (lower nutritional quality) was associated with a higher risk of cancer. This supports the relevance of the FSAm-NPS as underlying nutrient profiling system for front-of-pack nutrition labels, as well as for other public health nutritional measures.

    Influence of Probe Pressure on Ultrasound-Based Shear Wave Elastography of the Liver Using Comb-Push 2-D Technology2018Inngår i: Ultrasound in Medicine and Biology, ISSN 0301-5629, E-ISSN 1879-291XArtikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    It has been postulated that in the liver, applying increased probe pressure during ultrasound-based shear wave elastography (SWE) might lead to a false increase in the SWE result. We aimed to determine the influence of increased intercostal probe pressure when performing SWE of the liver. We also investigated the number of measurements required to achieve technically successful and reliable SWE examinations. This prospective, clinical study included 112 patients and 2240 SWE measurements of the liver. We applied probe pressure intercostally, to reduce the skin-to-liver capsule distance (SCD), which could stabilize the SWE signal and thus increase the number of technically successful measurements. We performed 10 measurements with maximum probe pressure and 10 with normal pressure in each patient. Thus, two analysis groups were compared for differences. Compared with normal pressure, maximum probe pressure significantly reduced the SCD (p < 0.001) and significantly increased the number of technically successful measurements from 981 to 1098, respectively (p < 0.001). The SWE results with normal and maximum probe pressure were 5.96 kPa (interquartile range: 2.41) and 5.45 kPa (interquartile range: 1.96), respectively (p < 0.001). In obese patients, a large SCD poses a diagnostic challenge for ultrasound SWE. We found that maximum intercostal probe pressure could reduce the SCD and increase the number of technically successful measurements, without falsely increasing the SWE result. Only three measurements were required to achieve technically successful and reliable SWE examinations.

    Latitudinal effects on crown shape evolution2018Inngår i: Ecology and Evolution, ISSN 2045-7758, E-ISSN 2045-7758, Vol. 8, nr 16, s. 8149-8158Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Large variations in crown shape are observed across the globe, from plants with wide and deep crowns to those with leaves clustered at the top. While there have been advances in the large-scale monitoring of forests, little is known about factors driving variations in crown shape with environmental conditions. Previous theoretical research suggests a gradient in crown shape with latitude, due to the effects of sun angle. Yet, it remains unclear whether such changes are also predicted under competition. Using a size-structured forest-growth model that incorporates self-shading from plants and competitive shading from their neighbors, we investigate how changes in site productivity and sun angle shape crown evolution. We consider evolution in two traits describing the top-heaviness and width-to-height ratio of crowns, shaped by trade-offs reflecting the costs and benefits of alternative architectures. In top-heavy trees, most of the leaves are at the top half of the trunk. We show that, contrary to common belief, the angle of sun beams per se has only a weak influence on crown shapes, except at low site productivity. By contrast, reduced site productivity has a strong effect, with trees growing in less productive sites keeping their leaves closer to the ground. The crown width-to-height ratio is generally higher at a lower site productivity, but this trait is not strongly influenced by any environmental factor. This theoretical analysis brings into question established beliefs about the effects of latitude on crown shapes. By introducing geometry-related growth constraints caused by shading from both the surrounding forest and the tree on itself, and costs for constructing and maintaining a three-dimensional crown, our analysis suggests crown shapes may vary with latitude, mostly via effects on overall site productivity, and less because of the angle of the sun.

    Single-phase active power harmonics filter by Op-Amp circuits and power electronics devices2018Inngår i: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 10, nr 12, artikkel-id 4406Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper introduces a new structure for single-phase Active Power Harmonics Filter (APHF) with the simple and low-cost controller to eliminate harmonics and its side effects on low voltage grid. The proposed APHF includes an accurate harmonic detector circuit, amplifier circuit to trap tiny harmonics, switching driver circuit for precise synchronization, and inverter to create injection current waveform, which is extracted from reference signal. The control circuits are based on electrostatic devices consist of Op-Amp circuits. Fast dynamic, simplicity, low cost, and small size are the main features of Op-Amp circuits that are used in the proposed topology. The aim is removing the all grid harmonic orders in which the proposed APF injects an appropriate current into the grid in parallel way. The proposed control system is smart enough to compensate all range of current harmonics. A prototype is implemented in the power electronics laboratory and it is installed as parallel on a distorted grid by the non-linear load (15 APeak-Peak) to verify the compensating of harmonics. The harmonics are compensated from THD% = 24.48 to THD% = 2.86 and the non-sinusoidal waveform is renovated to sinusoidal waveform by the proposed APHF. The experimental results show a good accurate and high-quality performance.

    Implications of Dual Band Functionality on Base Station Antenna Development1997Inngår i: Dual Band/Multi Band '97 / [ed] Center for EuroTelecomms, London, 1997Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The recent growth in cellular communications has rapidly created a need for more radio channels. In order to make better use of the available frequency bands new access techniques such as TDMA (Time Division Multiple Access), FDMA (Frequency DMA) and CDMA (Code DMA) have been introduced. Still, the need for new channels is strong and new frequency bands have therefore been allocated for wireless communication systems.

    These new communication systems, e.g. the European Personal Communication Network (PCN: 1710-1880MHz) and the North American Personal Communication System (PCS: 1850-1990MHz), use frequencies about twice as high as their predecessors (e.g. AMPS: 824-894MHz and GSM: 880-960MHz). However, at a time when our downtown areas already are littered with antennas, operators are not keen to install more.

    One solution could be to replace existing GSM or AMPS antennas with dual band GSM/PCN or AMPS/PCS. This would reduce the windload of the towers, the number of feeder cables and the whole  cost of tower installations. If the dual band antennas were to be dual polarized also, the four antennas today being needed for receiving the PCN and GSM bands in a sector, could actually be replaced by one only.

    Nederbördsintensitet och andra faktorer som påverkar skyfallsskador2018Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [sv]

    I Sverige inträffar många skyfall och intensiva regn under sommarmånaderna. Det finns inga uppenbara geografiska mönster, vilket är en skillnad gentemot älv- eller sjööversvämningar där det vanligtvis är känt vilka områden som kan komma att översvämmas vid en viss vattennivå eller ett visst vattenflöde. För individer och samhällsaktörer innebär en skyfallshändelse i många fall en stor överraskning då skyfall utvecklas snabbt och dagens meteorologiska prognossystem i stort inte lyckas att prognosticera extrema regn korrekt med avseende på mängd, tid och plats. Vädervarningar kommer med kort varsel eller uteblir helt. Konsekvenserna av intensiv nederbörd och skyfall är främst översvämningar och erosionsskador på byggnader och infrastruktur, men även störningar och avbrott i olika samhällsfunktioner som kan påverka samhället och individer utanför det drabbade området.

    I denna avhandling har 15 år av försäkringsskadedata använts för att undersöka samband mellan nederbördsintensitet och skyfallsskador. Även påverkan av andra faktorer som topografi, bebyggelse och socioekonomiska aspekter har undersökts. Resultaten visar att regnintensitet under ett 60 minuters intervall i kombination med korta perioder av extrem intensitet, tillsammans med topografiska faktorer spelar en betydande roll vid uppkomsten av skador.

    Predictors of hypertension in Mauritians with normotension and prehypertension at baseline: a cohort study2018Inngår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 15, nr 7, artikkel-id 1394Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Information on the predictors of future hypertension in Mauritians with prehypertension is scant. The aim of this study was to analyze the 5-year and 11-year risk of hypertension and its predictors in people with normotension and prehypertension at baseline in Mauritius in 1987. This was a retrospective cohort study of 883 men and 1194 women of Mauritian Indian and Mauritian Creole ethnicity, aged 25-74 years old, free of hypertension at baseline in 1987 with follow-up examinations in 1992 and 1998 using the same methodology. The main outcome was 5- and 11-year risk of hypertension. Odds ratios (OR) and corresponding 95% confidence intervals (CI) were calculated. The 5-year risk of hypertension was 5.4-times higher in people with prehypertension compared with normotensive individuals at baseline. The corresponding odds for prehypertensive people at baseline regarding 11-year hypertension risk was 3.39 (95% CI 2.67-4.29) in the adjusted logistic regression models. Being of Creole ethnicity (OR 1.42; 95% CI 1.09-1.86) increased the 11-year odds of hypertension compared with the Indian population. It is of importance to screen for people with prehypertension and implement strategies to reduce their systolic blood pressure levels to the recommended levels of 120/80 mmHg. Special attention needs to be given to Mauritians of Creole ethnicity.

    Conceptualising creativity benefits of nature experience: Attention restoration and mind wandering as complementary processes2018Inngår i: Journal of Environmental Psychology, ISSN 0272-4944, E-ISSN 1522-9610, Vol. 59, s. 36-45Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Accumulating evidence indicates that time spent in natural environments promotes creativity, but few researchers have considered how this occurs. We evaluate two candidate mechanisms, attention restoration and mind wandering. We compare the accounts in terms of attentional focus, brain network activation, cognitive effects, and the temporal progression of these processes across the stages of creativity. Based on this analysis, we propose that (1) gentle shifts between externally oriented soft fascination and internally oriented mind wandering can occur during nature experience; (2) this provides the basis for mutually reinforcing pathways that enhance attention control following nature experience; and (3) mind wandering might support additional benefits for creativity, including flexibility and new associations of ideas. We propose research to test the proposed pathways, including the conditions under which environments influence creativity, the ebb and flow of attention orientation during environmental experience, and the links between attentional focus, brain network activation and creativity.

    Test-Retest Reliability of The Participation Domain of the Stroke Impact Scale in Persons with Chronic Stroke2018Inngår i: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, Vol. 50, nr 9, s. 843-846Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: To evaluate the test-retest reliability and variability of the Participation domain of the Stroke Impact Scale (SIS Participation) in persons with stroke as it is widely used to assess perceived participation in rehabilitation after stroke.

    Design: A test-retest design. Subjects: Forty-five persons (mean age 65 years) with mild to moderate disability at least 6 months post-stroke.

    Methods: The SIS Participation domain was rated on 2 occasions, 1 week apart. The test-retest reliability of the total score was evaluated using Kappa statistics. The 8 item scores were evaluated by the proportion of participants who rated the same score (percentage agreement, PA) or +/- 1 point (PA <= 1 point) at T1 and T2. The Svensson method was used to evaluate systematic and random disagreement.

    Results: The test-retest reliability of the total score showed excellent agreement (Kappa coefficient = 0.79). The items showed high PA <= 1 point (> 82%). No items, except 2, showed a systematic disagreement, and no items showed a random disagreement according to the Svensson method.

    Conclusion: The SIS Participation domain is reliable in persons with chronic stroke and mild to moderate disability and can be used to assess perceived participation in this population.

    Fundamental Limitations of Distributed Feedback Control in Large-Scale Networks2018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    Networked systems accomplish global behaviors through local feedback interactions. The purpose of a distributed control design is to select interaction rules and control protocols that achieve desired global control objectives. In this thesis, we address the question of fundamental limitations to such control designs, in terms of the global performance that is achievable in large-scale networks. 

    We consider networked dynamical systems with single- and double- integrator dynamics controlled with linear consensus-like protocols. Such systems can be used to model, for example, vehicular formation dynamics and synchronization in electric power networks. We assume that the systems are subject to distributed disturbances and study performance in terms of H2 norm metrics that capture the notion of network coherence. In the context of power networks, we also show how such metrics can be used to quantify resistive losses caused by non-equilibrium, or transient, power flows due to a lack of synchrony. 

    Distributed static feedback control based on localized, relative state measurements is subject to known limitations that, for example, cause coherence metrics to scale unfavorably with network size in lattices of low spatial dimensions. This causes an inevitable lack of rigidity in one-dimensional formations, such as strings of vehicles. We show here that the same limitations in general apply also to dynamic feedback controllers that are locally of first order. The proof relies partly on a fundamental limitation of localized relative feedback in networks of integrators of order three or higher, which we show to cause instability if the network grows beyond a certain finite size. 

    This result holds unless the controller can access measurements of its local state with respect to an absolute reference frame, in which case dynamic feedback in the form of distributed derivative or integral control can fundamentally improve performance. This case applies, for example, to frequency control in power networks. However, if the absolute state measurements are subject to noise, the advantage of the distributed integral controller in terms of its performance scaling is lost. We show that scalable integral control of networks in principle requires centralization or all-to-all communication. 

    For electric power networks, we show that performance in terms of transient power losses scales with the number of generator nodes in a network. However, in sharp contrast to the previous results, an increased connectivity does not in general improve performance. We discuss possible implications of these results in terms of the design of future power grids with increasingly distributed electricity generation.

    Racing against age?: Gender, age, and body among senior participants in women-only sports races2018Inngår i: Loisir et Société, ISSN 0705-3436, E-ISSN 1705-0154, Vol. 41, nr 2, s. 297-310Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The purpose of this study is to investigate experiences and meaning-making of exercise and participation in races for women-only among Swedish senior women. Positioned within the framework of discourse theory, post-structuralism, and feminism, the article contains an analysis of how the intersection of gender, age, and the aging body affects articulations of meaning among senior participants in written accounts, interviews, and ethnographical fieldwork on women-only races in Sweden. The study shows that the senior women participate in women-only races in relation to (1) an aging, deteriorating body, (2) a health and exercise trend in Western society, (3) a desire for a single-gendered social context, (4) their own imagined physical (in)capability, (5) male-connoted capacities of physical strength, speed, and stamina, and (6) other senior female athletes who function as role models.

    Exoskeleton Gait Training After Spinal Cord Injury: An Exploratory Study on Secondary Health Conditions2018Inngår i: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, Vol. 50, nr 9, s. 806-813Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: To explore changes in pain, spasticity, range of motion, activities of daily living, bowel and lower urinary tract function and quality of life of individuals with spinal cord injury following robotic exoskeleton gait training.

    Design: Prospective, observational, open-label multicentre study. Methods: Three training sessions per week for 8 weeks using an Ekso GT robotic exoskeleton (Ekso Bionics). Included were individuals with recent (<1 year) or chronic (>1 year) injury, paraplegia and tetraplegia, complete and incomplete injury, men and women.

    Results: Fifty-two participants completed the training protocol. Pain was reported by 52% of participants during the week prior to training and 17% during training, but no change occurred longitudinally. Spasticity decreased after a training session compared with before the training session (p< 0.001), but not longitudinally. Chronically injured participants increased Spinal Cord Independence Measure (SCIM III) from 73 to 74 (p= 0.008) and improved life satisfaction (p= 0.036) over 8 weeks of training. Recently injured participants increased SCIM III from 62 to 70 (p<0.001), but no significant change occurred in life satisfaction. Range of motion, bowel and lower urinary function did not change over time.

    Conclusion: Training seemed not to provoke new pain. Spasticity decreased after a single training session. SCIM III and quality of life increased longitudinally for subsets of participants.

    Plasma stearoyl-CoA desaturase activity indices and bile acid concentrations after a low-fat meal: association with a genetic variant in the FTO gene2018Inngår i: Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy, ISSN 1178-7007, E-ISSN 1178-7007, Vol. 11, s. 611-618Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: Dietary macronutrient composition, stearoyl-CoA desaturase (SCD) activity indices, and primary bile acid (BA) concentrations are among the factors that have been associated with lipid metabolism and contributed to obesity. We investigated the association between the polymorphic expression of the fat mass and obesity-associated (FTO) gene and its relationship with SCD activity indices and primary BA concentrations after a low-fat meal. Subjects and methods: Blood plasma samples were collected from 56 young (20-36 years) healthy subjects with different rs9939609 FTO genotypes. Fasting and post-meal (2 hours after a low-fat breakfast) blood samples were collected on the subsequent morning for the analysis of DNA methylation, SCD activity indices (product-to-precursor fatty acid ratios; 16:1n-7/16:0 and 18: 1n-9/18:0), and chenodeoxycholic acid (CDCA) and cholic acid (CA) concentrations. Expression of lipogenic genes was investigated post-meal to assess the relationship between the CDCA and CA concentrations and mRNA levels of lipogenic genes. Results: The FTO AA (obesity risk) genotype group (n = 18) had higher (P<0.05) post-meal SCD-16 activity index than the FTO TT (wild type) genotype group (n=26). In both the FTO TT (n=16) and AA (n=8) genotype groups, the post-meal concentrations of CDCA and CA were lower (P<0.05) compared with the fasted state. No difference in BA concentrations between the FTO TT and AA genotype groups in both meal states was observed. After adjusting for the body mass index, the highest 50% post-meal concentrations of CA were inversely (P=0.010) correlated with the level of mRNA SCD expression. Conclusion: FTO AA carriers may be at a higher risk for obesity through higher SCD activity in a low-fat diet environment. This effect may be partly pronounced by very low CA concentrations.
