  2. 1. Evaluation of process parameters and treatments of different raw materials for biogas production

    Author : Malik Badshah; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; biogas; lignocellulosics; inoculum to substrate ratio; feed composition; toxicity; furaldehydes; paper and pulp sludges.;

    Abstract : The anaerobic digestion process results in the production of biogas from a large diversity of organic residues, which can be used as an alternate source of energy generation and for waste management. However, the biogas production technology is not exploited efficiently due to the characteristics of raw materials, poor methane yields, process instability, limited raw materials and lack of knowledge about the process.

  4. 2. Towards a Better Understanding and Control of Factors Affecting the Physical Quality of Fish Feed

    Author : Julia Wolska; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fish Feed; Physical quality; Durability; Aging; Crosslinking; Transglutaminase;

    Abstract : As aquaculture expands, the volume of fish feed produced and transported must also increase. Therefore a better understanding and increased control of the factors that influence the physical quality of feed pellets is required. To achieve this goal, reliable methods measuring the physical quality of feed are needed. READ MORE

  5. 3. Functionality of Spray-Dried Whey Protein Powders - Surface Composition, Particle Morphology and Rehydration

    Author : Ida-Marie Andersson; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Milk serum protein; Lactose; Whey protein powders; Spray drying; Particle morphology; Surface composition; Rehydration; Functionality; Milk serum protein; Lactose; Whey protein powders; Spray drying; Particle morphology; Surface composition; Rehydration; Functionality;

    Abstract : Whey protein powder functionality is expected to be closely linked to both structure and properties of the proteins. It is essential that whey protein powders are easily dispersed and dissolved in order to fulfil the specified nutrient content and the functionality in the final product. READ MORE

  6. 4. Nutrient utilisation in growing Cambodian cattle : effect of different feed sources and feed conservation techniques

    Author : Keo Sath; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Natural forages are an important part of the diet of cattle in Cambodia, but their nutrient value, particularly in terms of macro-minerals, may be inadequate, leading to potential mineral deficiencies in grazing cattle. This thesis compared the nutrient composition of six forage types (rice bran, rice straw, para grass, cassava foliage, leucaena leaves, water hyacinth leaves) from two regions in Cambodia against faecal and urinary excretion of macro minerals by cattle.

  7. 5. Influence of variations in feed ore characteristics on autogenous grinding

    Author : Roger Hahne; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : In autogenous mills, the grinding media derives from the feed ore itself. Variations in feed ore properties will therefore affect the grinding charge and thus, the resulting ground product will vary. READ MORE
