  1. 21. Extraktion av hemicellulosa från rapshalm

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Serwan Salim; [2016]
    Nyckelord :hemicellulosa; rapshalm; extraktion;

    Sammanfattning : Raps har odlats traditionellt i stor omfattning för att utvinna vegetabiliska oljor samt i form av biobränsle. Intresset har även ökat för rapshalmen då biopolymerer kan komma till nytta för produktion av material. LÄS MER

  3. 22. Reversible Modification Of Flexural Rigidity On Dry Archaeological Leather From Wet Anaerobic Burial Sites: An Herbal Method Irma

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Irma Wennerstrand; [2015-06-30]
    Nyckelord :cherry laurel leaves; flexural rigidity; archaeological leather; aldehyde; benzaldehyde; cyanogenic glycosides;

    Sammanfattning : This work is based on a treatment reported in the article “Über der Weichen trockengefallener Alkohol und Formalinpräparate, Herbarblätter und von Tapagewebe” in Der Präparator from 2001 by Klaus Weichsler and co-authors. A series of experiments were performed to investigate the described effect of cherry laurel leaves and the compounds emitted therefrom upon flexural rigidity of dry archaeological leather from wet burial sites, which upon uncontrolled drying becomes rigid.

    Författare :Annette Bick; [2015]
    Nyckelord :lactose crystallization; skim milk powder; glass transition; Technology and Engineering;

    Sammanfattning : Crystallization of amorphous lactose during storage at high relative humidity and high temperatures has been found to impair the quality of skim milk powders. This is related to the glass transition of lactose. LÄS MER

  7. 25. Methane emission from nitrate-treated tannin rich feed for cattle in Vietnam

    Kandidat-uppsats, SLU/Dept. of Animal Nutrition and Management
