  2. 1. Factors of importance for self-related health

    Author : Pia Svedberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Self-rated health; twins; genetic factors; environmental factors; sex; age; aging; cognitive abilities; epidemiology; health behavior;

    Abstract : Even though self-rated health is increasingly accepted as an important measure of health status, there are several uncertainties as to why people differ in their health perception. The extent of age differences across the life span and whether there are different determinants in men than in women is unclear. READ MORE

  4. 2. Studying ageing: experiences, description, variation, prediction and explanation

    Author : Bo G. Eriksson; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Gerontology; Demography; Longevity; Health promotion; Social facts; Sense of cohesion; Population; Random sample.;

    Abstract : The study follows a line of experiences, description, variation, prediction and explanation concerning ageing, health promotion and longevity. The experiences of aging were acquired during my studies of conversations, participation in longitudinal population studies in Gothenburg, and working with the Centre for Development of Home help services.

  5. 3. Hormonal regulation of hepatic cholesterol and lipoprotein metabolism : effects of estrogen and growth hormone

    Author : Paolo Parini; Karolinska Institutet; Karolinska Institutet; []
    Keywords : aging; atherosclerosis; bile acids; estrogen; estrogen receptor; cholesterol; growth hormone; growth hormone receptor; cholesterol 7[alpha]-hydroxylase; high density lipoprotein; hydroxy-methylglutaryl-coenzyme A reductase; hormones; hypercholesterolemia; hypophysectomy; insulin-like growth factor-I; low density lipoproteins;

    Abstract : Coronary heart disease is the result of the progression of atherosclerotic lesions, and represents the major cause of death in western countries. Age, male sex, plasma cholesterol, hypertension and smoking are major risk factors for atherosclerosis. READ MORE

  6. 4. Laser-Directed Energy Deposition : Influence of Process Parameters and Heat-Treatments

    Author : Suhas Sreekanth; Joel Andersson; Shrikant V. Joshi; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Directed Energy Deposition; Alloy 718; Process Parameters; Heat Treatments; Nb- rich Phases; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Laser-Directed Energy Deposition (L-DED), an Additive Manufacturing (AM) processused for the fabrication of parts in a layer-wise approach has displayed an immense potential over the last decade. The aerospace industry stands as the primary beneficiary due to the L-DED process capability to build near-net-shape components with minimal tooling and thereby producing minimum wastage because of reduced machining.

  7. 5. Diagnostics of stator insulatin by dielectric response and variable frequency partial discharge measurements : a study of varied low frequencies in stator insulation, with particular attention to end-winding stress-grading

    Author : Nathaniel Taylor; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Abstract : Stator insulation is a critical to the reliability of electrical generators and motors. It is common industrial practice to use electrical measurement of partial discharges (PD) and some form of current-voltage measurement as part of the condition assessment of stator insulation at maintenance times.
