    Författare :Mattias Öhman; Matz Dahlberg; Erik Grönqvist; Louise von Essen; Martin Karlsson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fluoride; Cognitive ability; Non-cognitive ability; Income; Education; Employment; Dental health; Mortality; Information; Health; Screening; Abdominal aortic aneurysm; Myocardial infarction; Antidepressants; SSRI; Propensity score matching; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of four self-contained papers.Essay I (with Linuz Aggeborn): Fluoridation of the drinking water is a public policy whose aim is to improve dental health. Although the evidence is clear that fluoride is good for dental health, concerns have been raised regarding potential negative effects on cognitive development. LÄS MER

  3. 12. Spatial variability of geogenic contaminants in drinking water sources : Insights into hydrogeological controls, geospatial data for safe water supply and groundwater resource management

    Författare :J. Ijumulana; Prosun Bhattacharya; Felix Mtalo; Steve W. Lyon; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drinking water; geogenic contaminants; potentially toxic elements; fluoride; spatial analysis; spatial variability; Tanzania; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : The presence of geogenic contaminants in drinking water is a major health concern in many parts of the world. The interaction of groundwater with different rock types and sediments in the natural geochemical environment play an important role in controlling their mobility. LÄS MER

  4. 13. On approximal caries prevention using fluoridated toothpicks, dental floss and interdental brushes

    Författare :Barbro Särner; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Approximal caries; Dental flosses; De- and re-mineralization; Fluoride; Interproximal aids; Interproximal area; Oral hygiene; Questionnaire; Toothpicks;

    Sammanfattning : Although dental health has improved during the last 40-50 years, approximal caries still constitutes a problem in many age groups. It is important that fluoride (F) toothpaste is used when brushing the teeth. In some subjects, there may be a need for supplementary F products, especially in the caries-prone approximal area.

  5. 14. Computational studies of Poly(vinylidene fluoride) and Poly(vinylidene fluoride) - Single Wall Carbon Nanotube Composites

    Författare :Martin Bohlén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular modeling; Carbon nanotubes; Poly vinylidene fluoride ;

    Sammanfattning : Poly(vinylidene fluoride) (PVDF) exhibits properties that allows the material to be used in such diverse areas as wire and cable products, electronic devices, membranes, exterior coatings for constructions and in the chemical, pharmaceutical and food industry as fluid-handling equipment. It is the inherent molecular structure of PVDF, where every second backbone carbon is bonded to two fluorine atoms, that gives the polymer several unique properties, among them piezo- and pyroelectricity.

  7. 15. Acid Tolerance of Streptococcus Mutans Biofilms

    Författare :Jessica Neilands; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acid tolerance; Streptococcus mutans; Biofilms; Acid stress; Fluoride;

    Sammanfattning : Mikrobiologisk forskning har till stor del bedrivits genom att man odlat bakterier i näringslösningar och på agarplattor och sedan studera bakterierna på olika sätt. Detta sätt att odla bakterier överensstämmer inte särskilt bra med hur bakterier växer i verkligenheten. LÄS MER
