  2. 6. Valorisation of fish waste biomass through recovery of nutritional lipids and biogas

    Author : Betty Mbatia; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; by-products; value addition; EPA; DHA; PUFA; biogas;

    Abstract : Commercial fish catch in Eastern Africa is dominated by Nile Perch. Of the fish that is processed for human consumption, 30-40% is wasted. Currently, these wastes are not fully utilized; they are sold off at low price, converted to low valued products or left to decompose leading to environmental pollution and wastage of bioresource.

  4. 7. RuO4 interaction with surfaces in the containment of nuclear power plant

    Author : Ivan Kajan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; containment; ruthenium; deposition; severe accident; re-vaporization;

    Abstract : During a severe accident different fission products will be released from the nuclear fuel and some of them may eventually reach the containment building. Ruthenium is considered to be an important fission product due to the possible formation of volatile oxides. READ MORE

  5. 8. Halogenated organic matter in precipitation

    Author : Krzysztof Laniewski; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Deposition in rain and snow plays a crucial role in the regional and global redistribution of a great variety of substances. This thesis is devoted to chemical characterisation and identification of the halogenated organic compounds that are most widespread in rain and snow. READ MORE

  6. 9. Crosslinking of Polymers. Molecular Structure and Properties of Sol and Network

    Author : Helena Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PDMS; long chain branchin; entanglement; crosslinking; contamination; network; bimodal; Silicone; polyethylene;

    Abstract : Crosslinking is a well-known procedure for improving a variety of features of polymers, particularly the dimension stability at elevated temperatures. Crosslinking implies the formation of a network, the gel, but there is always a certain portion of the material, the sol, that remains non-crosslinked within the network. READ MORE

  7. 10. Unlocking the Potential of Brewer’s Spent Grain : Sustainable Biorefinery Approach and Value-Added Product Generation

    Author : Mohsen Parchami; Mohammad J Taherzadeh; Sudip Rakshit; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brewer s spent grain; Hydrothermal pretreatment; Organosolv pretreatment; Edible filamentous fungi; Anaerobic digestion; Biorefinery; Resource Recovery; Resursåtervinning;

    Abstract : Brewer’s spent grain (BSG) constitutes 85% of brewing byproducts and 30% of initial malt. In 2021, BSG production reached approximately 37.2 million tons. Owing to its high moisture and nutritional content, BSG is prone to biological deterioration, causing environmental issues when discarded as waste. READ MORE
