  • Vertically aligned carbon based varactors
  • 2011
  • In: Journal of Applied Physics. - : AIP Publishing. - 0021-8979 .- 1089-7550. ; 110:2
  • Journal article (peer-reviewed)abstract
    • This paper gives an assessment of vertically aligned carbon based varactors and validates their potential for future applications. The varactors discussed here are nanoelectromechanical devices which are based on either vertically aligned carbon nanofibers or vertically aligned carbon nanotube arrays. A generic analytical model for parallel plate nanoelectromechanical varactors based on previous works is developed and is used to formulate a universal expression for their voltage-capacitance relation. Specific expressions for the nanofiber based and the nanotube based varactors are then derived separately from the generic model. This paper also provides a detailed review on the fabrication of carbon based varactors and pays special attention to the challenges in realizing such devices. Finally, the performance of the carbon based varactor is assessed in accordance with four criteria: the static capacitance, the tuning ratio, the quality factor, and the operating voltage. Although the reported performance is still far inferior to other varactor technologies, our prognosis which stems from the analytical model shows a promise of a high quality factor as well as a potential for high power handling for carbon based varactors.

  • Experiences of health-promoting self-care in people living with rheumatic diseases
  • 2011
  • In: Journal of Advanced Nursing. - Oxford : Wiley. - 0309-2402 .- 1365-2648. ; 67:6, s. 1264-1272
  • Journal article (peer-reviewed)abstract
    • Aim This paper is a report of a study which explores and describes the meaning of the phenomenon health-promoting self-care as experienced by people living with rheumatic diseases.Background People with rheumatic diseases estimate health status as low and health belief and health status influence the self-care behaviours. Several self-care behaviours are used in the efforts to mitigate the diseases.Method The study had a descriptive phenomenological approach based on a reflective life-world perspective. Data were gathered in 2007 by unstructured open-ended interviews with 12 individuals living with rheumatic diseases.Findings The meaning of health-promoting self-care as experienced by people living with rheumatic diseases was that self-care takes place against a background of continual hope and belief to influence health in positive ways. Self-care was a way of life and implied being ready to understand and respond to signals from the body. Three inter-related constituents elucidated the experiences: dialogue, power struggle and choice. Self-care was experienced as dialogues within the body and with the immediate environment. In order to respond to signals from the body, power struggles were required to be entered when fighting the diseases. Choices were required to be made and things that were beneficial for the body were prioritized.Conclusion In this study, the meaning of health-promoting self-care as experienced by people living with rheumatic diseases was that self-care was a way of life. This meant to be ready to understand and respond to signals from the body. Self-care required dialogues, power struggles and choices.

  • People with Rheumatic Diseases Experiences of Health-Promoting Self-Care
  • 2010
  • In: Annals of the Rheumatic Diseases. - London : BMJ Books. - 0003-4967 .- 1468-2060. ; 69:Suppl. 3, s. 743-743
  • Journal article (peer-reviewed)abstract
    • Background: People with rheumatic diseases estimate their health status low. The health status and health belief are influencing the choice of self-care behaviours. Self-care behaviours are common and could prevent loss of valued life activities and health. Little is known of how people with rheumatic diseases experience self-care.Objectives: To describe people with rheumatic diseases experiences of health-promoting self-care.Methods: The study had a phenomenological approach based on a reflective life-world perspective. Data were gathered by unstructured and open-ended interviews with 12 individuals with various diagnoses of rheumatic diseases.Results: For people with rheumatic diseases, self-care was a way of life and implied being ready at all times to understand and respond to signals from the lived body. Self-care was experienced as an internal dialogue within the lived body but also as an external dialogue with the immediate environment. Self-care could also be described as a power struggle where the individuals strived and forced themselves to fight the diseases and its concrete consequences. The self-care also required that choices were made. Crucial for the choices were trust in oneself and belief in one's own ability to chosen health-promoting self-care. The individual prioritised self-care that was experienced as a beneficial and/or a reward for the lived body.Conclusion: People with rheumatic diseases experienced self-care as a way of life and that it meant to be ready at all times to understand and respond to signals that the lived body sends out. Self-care required dialogue, power struggle and choice. This knowledge ads to a fuller understanding of factors that from a patient perspective are important for health when living with a chronic rheumatic disease.Disclosure of Interest: None declared

  • Extreme storms in Malmo, Sweden
  • 2010
  • In: Hydrological Processes. - : Wiley. - 1099-1085 .- 0885-6087. ; 24:24, s. 3462-3475
  • Journal article (peer-reviewed)abstract
    • Short-term very intensive storms in the years 1980-2007 from rain gauges in Malmo have been analysed to find intensities of long return periods and to investigate trends. Observations from different stations have been pooled into series to which probability functions have been adjusted. Quality control of short-term precipitation records is emphasized. In order to investigate whether high rain intensities are different today compared to back in time, new and old rain data have been compared. Trends over the last 25 years have been computed for storms of duration 10 min to 1 h, and for 89 years of daily rains. A literature review of investigations of changing rain intensities is presented. It is found that 10- to 25-year long rain series from single stations are too short to give good estimates of storms of long recurrence time because a single event influences much. The largest observed rains in Malmo in the investigated period have a return period of about 20-50 years. For the very short-term storms, 50-year old intensity-duration-frequency curves do not differ much from those derived from new data. Trend analysis shows changing short-term high storm intensities only for storms of 10-min duration. (C) Copyright. 2010 John Wiley & Sons, Ltd.
