  1. 16. Evaluation of Esterification as a Valorization Route for Oxidized Lignin

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Johanna Lindmark; [2017]
    Nyckelord :Lignin; Kraft Lignin; Esterification; Peracetic Acid; Oxidized Lignin; Muconic Acid; Vanillic Acid;

    Sammanfattning : RISE Bioeconomy is working with the biorefinery concept. That is, for the company, to utilize all wood derivatives in effective processes, resulting in unique products. RISE Bioeconomy is investigating the possibilities of producing holocellulose through an oxidative delignification process of wood, using peracetic acid (PAA). LÄS MER

  3. 17. Behavioural studies and collection of volatiles to identify the pheromone(s) of the great Capricorn (Cerambyx cerdo)

    Kandidat-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Fredric Svensson; [2016]
    Nyckelord :Cerambyx cerdo; Cerambycidae; great Capricorn; chemical ecology;

    Sammanfattning : This work was aimed at identifying the pheromone component(s) of the great Capricorn longhorn beetle (Cerambyx cerdo). Volatile samples from beetles were obtained by means of collection of headspace volatiles from the animals, and by direct solvent extraction of body parts, and analysed by gas chromatography-mass spectrometry (GC-MS) and gas chromatography- Electroanntennography (GC-EAG).

  4. 18. Quantification of short chain fatty acids in serum and plasma

    Kandidat-uppsats, SLU/Dept. of Food Science

    Författare :Jonna Skoglund; [2016]
    Nyckelord :short chain fatty acids; type 2 diabetes; GC-MS; dietary fibre; serum; plasma;

    Sammanfattning : Type 2 diabetes (T2D) has become a major problem around the world. Current research has linked a high dietary fibre (DF)- intake with a number of health benefits and possible prevention of T2D. One proposed mechanism is via short chain fatty acids (SCFA), which are produced from fermentation of DF in the colon by the microflora. LÄS MER

  5. 19. Keramikk - fortidens stemme : Lipidanalyse på keramikk fra Påtåker, Sollentuna, Uppland, Sverige.

    Kandidat-uppsats, Stockholms universitet/Institutionen för arkeologi och antikens kultur

    Författare :Kathrine Wehmer; [2016]
    Nyckelord :Archaeology; Scandinavia; ceramic; potsherd; Food culture; Early iron age; GC-MS; Gas chromatography-mass spectrometry; Påtåker; Lipid analysis;

    Sammanfattning : This paper is about food culture in Uppland under early iron age in Upplans, Sverige. Gas chromatography–mass spectrometry (GC-MS) was used to analysis the lipids that were extracted from archaeological potsherds from Påtåker Raä 62, Sollentuna, Uppland. LÄS MER

  7. 20. Alkylresorcinols as a biomarker for whole grain rye and wheat intake in the finnish diabetes prevention trial

    Kandidat-uppsats, SLU/Dept. of Food Science

    Författare :Elise Nordin; [2015]
    Nyckelord :T2D; whole grain; rye; wheat; C17 C21; biomarker; alkylresorcinols; gas chromatography- mass spectrometry GC-MS ;

    Sammanfattning : Type 2 diabetes (T2D) is a public health problem of great concern. Globally it is increasing and it generates a huge economic burden to society and problems for the individuals. LÄS MER
