  1. 1. Novel oil resistant cellulosic materials

    Författare :Christian Aulin; Lars Wågberg; Derek Gray; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oleophobic; MFC; cellulose; oil resistant; contact angle; XPS; SEM; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The aim of this study has been to prepare and characterise oil resistant cellulosic materials, ranging from model surfaces to papers and aerogels. The cellulosic materials were made oil resistant by chemical and topographic modifications, based on surface energy, surface roughness and barrier approaches. LÄS MER

  3. 2. Means to Optimize the Nutritional Properties of Starch in Potato Products - Impact on glycaemia, satiety and resistant starch content

    Författare :Margareta Leeman; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Näringslära; amylopectin; starch; glycaemic index; resistant starch; Nutrition; vinegar; satiety; amylose; Solanum tuberosum; potato;

    Sammanfattning : Despite decreased consumption potatoes still constitute an important staple in the Swedish diet. An objection to potatoes and potato products from a nutritional point of view is the ease by which the starch is digested and absorbed in the gastrointestinal tract. LÄS MER

  4. 3. Evaluation of an automatic urinometer including use of silicone oil to decrease biofilm formation due to proteinuria, hemoglobinuria and bacterial growth

    Författare :Martin Slettengren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: A new capacitance-based automatic urinometer (AU) facilitates continuous urine output (UO) measurement, which may help to predict and diagnose acute kidney injury (AKI). To prevent mismeasurement due to bacterial, albumin or free hemoglobin biofilm, a water-soluble capsule with silicone oil has been integrated in the device. LÄS MER

  5. 4. Environmental records of carbonaceous fly-ash particles from fossil-fuel combustion

    Författare :Maria Wik; Lars Ericson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbonaceous particles; soot; anthropogenic particles; oil and coal combustion; fossil fuel combustion; lake sediments; lake acidification; forest soils; historical monitoring;

    Sammanfattning : Fossil fuel combustion produces fly-ash particles that are released into the atmosphere and deposited in the environment. A particularly characteristic kind of fly-ash is spheroidal carbonaceous particles. They are composed of an amorphous carbon matrix in which other elements are dispersed. LÄS MER

  7. 5. Quinolone resistance in Bacteroides fragilis and Pseudomonas aeruginosa, two opportunistic pathogens

    Författare :Herin Oh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Quinolone; resistance; B. fragilis; P. aeruginosa; topoisomerase; efflux;

    Sammanfattning : Opportunistic pathogens can cause infections in case of structural or functional defects in the host. Examples of Gram-negative opportunists are the Bacteroides fragilis group, anaerobic, non-spore forming rods and the aerobic, non-fermentative rod Pseudomonas aeruginosa. LÄS MER
