  1. 1. Modelling and Validation of Industrial Measurement Systems - Aspects of Quality and Human Factors

    Författare :Jenny Wirandi; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty Analysis; Quality Index; Instrumentation technology; Mät- och instrumenteringsteknik; Traceability; Fuzzy Variable; Pulp Quality; Industrial Measurement; Human Factor; GUM; Calibration; Fibre Measurement; Measurement Science;

    Sammanfattning : Although there is a fairly large number of books and articles concerning the validation of technical measurement systems, there are only a few which take into account the whole measurement system consisting of both technical and non-technical aspects. A measurement system comprises both the measurement process and the human being who conducts the measurement. LÄS MER

  3. 2. Chewing gum and human hair as retrospective dosimeters

    Författare :Axel Israelsson; Håkan B.L. Pettersson; Eva Lund; Håkan Gustafsson; Mats Eriksson; Bastian Breustedt; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Retrospective dosimeters are sometimes needed after radiological/nuclear (RN) exposures to determine the doses to individuals. Conventional dosimeters may not be at hand or may not be applicable calling for alternative materials. LÄS MER

  4. 3. Polymer Gels as Pharmaceutical Dosage Forms : Rheological Performance and Physicochemical Interactions at the Gel-Mucus Interface for Formulations Intended for Mucosal Drug Delivery

    Författare :Helene Hägerström; Katarina Edsman; Arne Brodin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; gel; rheology; mucoadhesion; mucosal drug delivery; in situ gel; gellan gum; Carbopol; tensile strength; nasal mucosa; intranasal administration; dielectric spectroscopy; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Sammanfattning : Drug delivery to the nasal and ocular mucosa faces several obstacles. One of these is from the effective clearance mechanisms present in the nose and eye. Polymer gels with suitable rheological properties can facilitate the absorption of poorly absorbed drugs by increasing the contact time of the drug with the mucosa. LÄS MER

  5. 4. Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans

    Författare :Tannaz Ghaffarzadegan; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bile acids; Dietary fibre; Fat; Pectin; Guar gum; Barley; Lingonberry; Turmeric; Short-chain fatty acids; Gut microbiota; Caecum; Serum; Rat; Mice; Humans; GC-FID; UHPLC-MS;

    Sammanfattning : Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. LÄS MER

  7. 5. Xylitol and its effect on oral ecology : clinical studies in children and adolescents

    Författare :Pernilla Lif Holgerson; Svante Twetman; Christina Stecksén-Blicks; Eva Söderling; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chewing gum; dental plaque; dose-response relationship; interdental plaque-pH; oral microorganisms; saliva; xylitol; Paedodontics; Pedodonti;

    Sammanfattning : Xylitol, classified as a natural sugar substitute, has for about 35 years been known as an agent that may act against caries. The mechanism of action; how it inhibits mutans streptococci (MS) and the clinical dose-response relationship are not however fully investigated. LÄS MER
