  2. 1. Continuous Preventive Bridge Maintenance : Effect of High Pressure Washing on Concrete Bridges

    Author : Louise Andersson; Johan Silfwerbrand; Anders Selander; Ylva Edwards; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge maintenance; preventive maintenance; chloride ingress; high-pressure washing; Concrete Structures; Betongbyggnad;

    Abstract : In Sweden, as in many other countries, preventive maintenance of structures andbridges is considered important. It provides several benefits such as prolonged lifespan or service life, less need for repair, and hopefully reduced costs and lowerenvironmental impact.A large part of Sweden’s bridge stock is getting quite old.

  4. 2. Faecal incontinence : Aspects of diagnosis and treatment

    Author : Asbjörn Österberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Faecal incontinence; anorectal manovolumetry; high pressure zone profile; pudendal nerve terminal motor latency; fibre density; questionnaire; electrostimulation; levatorplasty; sphincteroplasty; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : Rectal reservoir function and anal pressures were investigated using anorectal manovolumetry in 48 patients with faecal incontinence and in 25 control subjects. Resting and squeeze pressures were lower in patients (p... READ MORE

  5. 3. Hypertension in Vietnam : from community-based studies to a national targeted programme

    Author : Pham Thai Son; Peter Byass; Alexandra Krettek; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hypertension; risk factor; community; programme; Vietnam; folkhälsa; Public health;

    Abstract : Background: In the context of transitional Vietnam, hypertension has been shown to be one of the ten leading causes of morbidity and mortality in hospitals. However, population-based data on hypertension are to a large extent lacking. READ MORE

  6. 4. Model catalysts studied by x-rays, visible and infrared light

    Author : Stefano Albertin; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High Energy Surface X-ray Diffraction; X-ray Photoelectron Spectroscopy; oxidation; Pd 100 ; PdO; Ir 100 ; IrO2; in-situ; operando; Surface Optical Reflectance;

    Abstract : This work is focused on the study of transition metal model catalysts for gas-phase heterogeneous catalysis, studied with light-based in-situ and operando techniques.Metallic model catalysts, such as Palladium (Pd) and Iridium (Ir) single crystals and in minor part deposited Rhodium (Rh), were studied using a combination of x-ray and non x-ray techniques.

  7. 5. Precipitation phase determination in cold region conceptual models - analysis and method development

    Author : James Feiccabrino; Avdelningen för Teknisk vattenresurslära; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Snow Models; Precipitation Phase Uncertainty; ; Snow; Conceptual Model; Cold Regions;

    Abstract : Precipitation phase uncertainty is a known source of error in conceptual models used for many hydrological, climatological, and environmental applications. These conceptual models often use the simple approach of calibrating an air temperature threshold (TRS) over a large area irrespective of physiographic characteristics such as distance to the ocean and topographic relief.
