    • By the food intake man is daily exposed to numerous chemical agents with impact on ageing and longevity. Over the last two centuries longevity in the affluent societies has increased by 2 years per decade. Improved food habits are important contributing factors.  Dietary patterns of populations with long life-spans, like the traditional Mediterranean diet and the Okinawa Island diet, provide the basis to recommend plant foods like vegetables, legumes, fruits, non-tropical vegetable oils as basic fat, light meat (e.g. poultry) of moderate amounts, plenty of fish and moderate beverage intakes of wine, coffee and tea. Oxidative damage is suggested as one major reason for exaggerated ageing. Foods that promote longevity are rich in antioxidants. Still there is no evidence that extra anti-oxidant supplementation has any beneficial effects. Energy balance to avoid obesity at young and middle ages, e.g. by calorie restricted diets and increased physical activity, promotes longevity, whereas at older age overweight is usually associated with a longer life-span.

  • Evaluation of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) in persons with heart disease : a pilot study
  • 2010
  • Ingår i: European Journal of Cardiovascular Nursing. - 1474-5151. ; 9:3, s. 168-174
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: As part of preparation for a Swedish multicentre study, exploring sexual and married life in patients with myocardial infarction and their partners, a Swedish validated instrument was required.Aims: The aim of this pilot study was to evaluate the validity and reliability of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) among persons with a heart disease.Methods: A convenience sample of 79 persons (47 men and 32 women) living with a heart disease was recruited from the members of the National Association of Heart and Lung Patients. They completed a Swedish version of the WSFQ on two occasions.Results: Two separate factor analyses each revealed a two-factor structure on both occasions: “Sexual appetite” and “Sexual expectations” with gender-neutral questions and “Sexual sensitiveness” and “Sexual ability” with gender-specific questions. Cronbach's alpha coefficients ranged from 0.48 to 0.86 and test–retest values for all but one question exceeded 0.70.Conclusions: The Swedish version of the WSFQ showed good validity and stability and acceptable internal homogeneity. Extended evaluations of the questionnaire are recommended.

  • Validity and reliability of a Swedish version of the Relationship Assessment Scale (RAS) : a pilot study
  • 2010
  • Ingår i: Canadian journal of cardiovascular nursing. - Ottawa : Canadian Council of Cardiovascular Nurses. - 0843-6096. ; 20:1, s. 16-21
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: There is a need for a short and easily administered scale, in the Swedish language, for assessing partner relationships in the health care of persons with cardiac disease. PURPOSE: To establish the reliability and validity of the Swedish version of the Relationship Assessment Scale (RAS). DESIGN: The present pilot study has a methodological design. FINDINGS: Content validity has been tested for relevance, clarity and readability. The scale was tested for construct validity with explorative factor analysis. The reliability was tested by internal consistency and test-retest analysis. The result showed a two-factor solution, which does not correspond to the original proposed one-factor solution. The factor analyses revealed two quite distinct factors of RAS, labelled "Relationship built on expectations and satisfaction of needs" and "Relationship built on love and devotion". CONCLUSIONS: The scale has satisfactory psychometric properties in terms of content validity, construct validity, homogeneity and stability in a population of persons with cardiac disease. Wider evaluations of the RAS for other populations and settings are recommended.

  • Influence of alumina on physical properties of an industrial zinc-copper smelting slag : Part 1 - Viscosity
  • 2013
  • Ingår i: Transactions of the Institution of Mining and Metallurgy Section C - Mineral Processing and Extractive Metallurgy. - 0371-9553. ; 122:1, s. 42-48
  • Tidskriftsartikel (refereegranskat)abstract
    • The rotating cylinder method was applied to measure the viscosities of an industrial iron silicate slag and mixtures of this slag with 5, 10 and 15 wt-% alumina addition, in temperature range 1100-1300 C. The measured viscosities were compared with the predicted values using two of the commercially available software products for viscosity calculations, namely Thermoslag®1·5 and FactSageTM6·2. As the models can only predict viscosities for a solid free melt, obtained values by FactSageTM6·2 were modified using the Einstein-Roscoe equation. Results show that aluminium behaves as a network former cation in this type of slag, and by increasing the alumina concentration, the melt becomes progressively polymerised. Consequently, the viscosity of the slag increases at a given temperature, which is supported by thermodynamic predictions. According to the modified FactSage TM6·2 calculations, the viscosity of the solid containing slag increases from 2·1 to 5·5 poise at the industrial operating temperature (∼1250 C).

  • Stove performance and emission characteristics in residential wood log and pellet combustion : Part 2: Wood stove
  • 2011
  • Ingår i: Energy & Fuels. - American Chemical Society. - 0887-0624. ; 25:1, s. 315-323
  • Tidskriftsartikel (refereegranskat)abstract
    • The characteristics and quantities of a large number of gaseous and particulate emission components during combustion in a residential wood log stove with variations in fuel, appliance and operational conditions were determined experimentally. The measurement campaign included CO, NOx, organic gaseous carbon (OGC), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), total particulate matter (PMtot) as well as particle mass and number concentrations, size distributions, and inorganic composition. CO varied in the range of 1100 to 7200 mg/MJfuel, while OGC varied from 210 to 3300 mg/MJfuel. Dominating VOCs were methane, followed by ethene, acetylene, and benzene. Methane varied from 9 to 1600 mg/MJfuel. The nonmethane volatile organic compound (NMVOC) emissions were in the range of 20−2300 mg/MJfuel. The PAHtot emissions varied from 1.3 to 220 mg/MJfuel, in most cases dominated by phenantrene, fluoranthene, and pyrene. PMtot were in all cases dominated by fine particles and varied in the range 38−350 mg/MJfuel. The mass median particle diameters and the peak mobility diameters of the fine particles varied in the range 200−320 and 220−330 nm, respectively, and number concentrations in the range of 1−4 × 1013 particles/MJfuel. Air starved conditions, at high firing intensity, gave the highest emissions, especially for hydrocarbons. This type of condition is seldom considered, though it may occur occasionally. The emissions from Swedish wood stoves, comparing a Swedish field study, are covered fairly well with the applied methodology, but other field studies report considerably higher emissions especially for diluted particle sampling.

    • The aim of this article is to discuss challenges in the development of Specialist Nursing Educations as a result of the 2007 Swedish Higher EducationReform: the implementation of the so-called Bologna process. Certain challenges follow this reform, particularly since the specialist nursingprogrammes will be part of the second cycle of the higher education system, and it will be possible to combine the professional degree witha masters degree (one year). Possible strategies in four areas related to the Specialist Nursing Education are discussed: integration of researchbasedknowledge, experienced-based knowledge, improvement knowledge, and strategies for collaboration between university institutions andclinics. Specific didactical issues are raised.

  • Psychometric evaluation of “The 25-item Sex after MI Knowledge Test” in a Swedish context
  • 2012
  • Ingår i: Scandinavian Journal of Caring Sciences. - 0283-9318. ; 26:1, s. 203-208
  • Tidskriftsartikel (refereegranskat)abstract
    • The patients’ sexual life after a myocardial infarction is important for his/her quality of life. In spite of this, many patients are in doubt regarding their sex life after a myocardial infarction (MI) and the sexual information received, and counselling from health care providers has been seen to be insufficient. The purpose of this study was to evaluate the psychometric properties of ‘The 25-item Sex after MI Knowledge Test’ in a Swedish context. A convenience sample was recruited. The scale was translated into Swedish and completed by 79 former patients from The Heart and Lung Patients’ National Association on two occasions, with an interval of 2 weeks. The scale was tested for face and content validity, internal consistency and test–retest reliability. The result in this study indicates that the instrument has good face and content validity and displayed a moderate internal consistency (alpha 0.61). The instrument showed some level of instability in test–retest reliability with 60% of the items presenting moderate or strong agreement between the test and retest. Further studies that use this instrument in larger and more diverse samples are thus needed.

  • The Swedish version of the Frommelt attitude toward care of the dying scale : Aspects of validity and factors influencing nurses' and nursing students' attitudes
  • 2014
  • Ingår i: Cancer Nursing. - Lippincott Williams & Wilkins. - 0162-220X. ; 37:1, s. E1-E11
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Nurses' attitudes toward caring for dying persons need to be explored. The Frommelt Attitude Toward Care of the Dying (FATCOD) scale has not previously been used in Swedish language. OBJECTIVES: The objectives of this study were to compare FATCOD scores among Swedish nurses and nursing students with those from other languages, to explore the existence of 2 subscales, and to evaluate influences of experiences on attitudes toward care of dying patients. METHODS: A descriptive, cross-sectional, and predictive design was used. The FATCOD scores of Swedish nurses from hospice, oncology, surgery clinics, and palliative home care and nursing students were compared with published scores from the United States, Israel, and Japan. Descriptive statistics, t tests, and factor and regression analyses were used. RESULTS: The sample consisted of 213 persons: 71 registered nurses, 42 enrolled nurses, and 100 nursing students. Swedish FATCOD mean scores did not differ from published means from the United States and Israel, but were significantly more positive than Japanese means. In line with Japanese studies, factor analyses yielded a 2-factor solution. Total FATCOD and subscales had low Cronbach α's. Hospice and palliative team nurses were more positive than oncology and surgery nurses to care for dying patients. CONCLUSIONS: Although our results suggest that the Swedish FATCOD may comprise 2 distinct scales, the total scale may be the most adequate and applicable for use in Sweden. Professional experience was associated with nurses' attitudes toward caring for dying patients. IMPLICATION FOR PRACTICE: Care culture might influence nurses' attitudes toward caring for dying patients; the benefits of education need to be explored.
