  2. 1. Interfacing spectrophotometry to process liquors applications to kraft pulping

    Author : Xiaotian Yang; KTH; []
    Keywords : Kraft cooking; On-line; Sulfide; Lignin; Polysulfide excess sulfur; Anthraquinone-2-sulfonate; Anthraquinone; Nafion membrane; UV-Vis; ATR-probe; Spectrophotometric;

    Abstract : This thesis summarizes the outcome of work performed withthe objective to contribute to the knowledge and development ofthe kraft cooking process using spectrophotometricinterfaces.In kraft cooking, it is desirable to maximize the removal oflignin in the cook without loss of pulp strength.

  4. 2. Reactor Applications and Process Monitoring for Improved Anaerobic Digestion

    Author : Tor Gunnar Jantsch; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pH-indicators; spectrophotometric; Biotechnology; Bioteknik; alkalinity; monitoring; UASB reactor; spent sulphite liquor; caustic extraction liquor; sulphite evaporator condensate; pulp wastewater; Anaerobic digestion; biogas;

    Abstract : Biogas, a mixture of methane and carbon dioxide, is produced by microorganisms upon degradation of organic matter in an anaerobic environment. It has been realised that by utilising anaerobic processes the organic pollutants in wastewater and organic solid waste from anthropogenic sources can be converted into a renewable source of energy.

  5. 3. Aspects on in vivo imaging techniques for diagnostics of pigmented skin lesions

    Author : Karin Terstappen; Göteborgs universitet; []
    Keywords : Melanoma; pigmented nevi; basal cell carcinoma; differential diagnosis; dermoscopy; spectrophotometric intracutaneous analysis; pathology;

    Abstract : Abstract Problem: Non-invasive diagnostic techniques to facilitate diagnosis of pigmented skin lesions (PSL) are being developed. Dermoscopy and SIAscopy are two such techniques, and they are evaluated in this thesis. READ MORE

  6. 4. Fundamental research on supercritical fluid extraction kinetics : From on-line measurements to inverse modeling

    Author : Victor Abrahamsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supercritical fluid extraction; supercritical fluid chromatography; linseed; microalgae; extraction kinetics; inverse modeling; curve resolution;

    Abstract : Supercritical fluid extraction is an extraction technique suitable for lipophilic compounds from solid samples. Most commonly supercritical carbon dioxide is the main component in the extraction phase, rendering the technique relatively environmentally benign. READ MORE

  7. 5. Thylakoid membrane from spinach - effect of processing on their function as appetite suppressing ingredient

    Author : Karolina Östbring; Aptitkontroll; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drying; Storage Conditions; Appetite; Thylakoids; Heat treatment; Chlorophyll; Spinach;

    Abstract : Western diet contains a high proportion of palatable food, rich in refined carbohydrates and fat, that subsequently increases the risk of overconsumption and possibly leads to overweight and obesity. Therefore an approach to strengthen the inherent satiety for fat can be used to prevent overconsumption. READ MORE
