  1. 21. Effect of Ischaemia-Reperfusion on Rabbit Kidney and Human Brain

    Författare :Jagdish Shivlal Gondalia; Göteborgs universitet; []
    Nyckelord :Free radicals; ischaemia-reperfusion; cell bioenergetics; NMR; ESR; carotid artery stenosis; endarterectomy; allopurinol; acetylcysteine; MMP-1; ICAM-1; MCP-9; oxLDL;

    Sammanfattning : Free radicals are produced in various organs at ischaemia-reperfusion. The final stage in radical damage is lipid peroxidation. We have demonstrated previously that a lipid-soluble antioxidant improves restoration of bioenergetics in rabbit kidneys after ischaemia, as reflected in 31P spectrometry. LÄS MER

  3. 22. Biological Pretreatment and Dry Digestion Processes for Biogas Production

    Författare :Regina Patinvoh; Thierry Ribeiro; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid wastes; Dry anaerobic digestion; Textile bioreactor; Plug flow bioreactor; Digestate; Process stability; Pretreatment; Co-digestion; Mesophilic; Resource Recovery; Resursåtervinning;

    Sammanfattning : Biogas technology has been used quite extensively to generate renewable energy from organic wastes while also recycling nutrients in the wastes and reducing harmful emissions. However, the challenges of low biogas yield from recalcitrant and inhibitory solid wastes together with high construction and operation costs of bioreactors have impeded optimal performance through this process.

  4. 23. Sample preconcentration in open microchannels : Combinations with MALDI and nano-ESI mass spectrometry and computer simulations

    Författare :Saara Mikkonen; Åsa Emmer; Leopold Ilag; Jenny Ottosson Takanen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Preconcentration; open microchannel; microchip; MALDI; electrospray ionization; nanoelectrospray; mass spectrometry; computer simulation;

    Sammanfattning : In this thesis a novel concept for preconcentration of biomolecules in open microchannels is presented. The preconcentration is based on electromigration of charged analytes, and detection is performed with matrix-assisted laser desorption/ionization (MALDI) or nano-electrospray ionization (nESI) mass spectrometry (MS).

  5. 24. Acetylation of polysaccharides in plant cell wall : with a focus on woody species

    Författare :Prashant Mohan Pawar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plant cell wall in woody tissues is a complex matrix, which consists of cellulose, matrix polysaccharides and lignin. The matrix polysaccharides are substituted with acetyl group that are hypothesised to play important roles in determining properties of these polysaccharides. LÄS MER

  7. 25. COMBINED DEHYDRATION METHODS - From Fresh Fruit to High-quality Ingredients

    Författare :Frédéric Prothon; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; semi-finished products; agent; collapse; apple; microwave-assisted air-drying; dehydration; osmotic treatment;

    Sammanfattning : Numerous products from the food industry contain fruit and/or berries, in the form of fillings or ingredients, e. g. in yoghurt, some bread products/cereal products, ice cream, etc. In order to produce these ingredients and improve their characteristics, many processing techniques are available.
