    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; indirect environmental impact; fuel-cycle emissions; environmental systems analysis; energy systems analysis; energy balance; digestate; Anaerobic digestion; biogas;

    Abstract : Anaerobic digestion and the production of biogas can provide an efficient means of meeting several objectives concerning energy, environmental and waste management policy. Interest in biogas is increasing, and new facilities are being built. READ MORE

  4. 2. Biofuels from Kraft Black Liquor : Pilot-Scale Gasification Development and Techno-Economic Evaluation of Industrially Relevant Biofuel Production Pathways

    Author : Yawer Jafri; Erik Furusjö; Ilkka Hannula; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; black liquor; pyrolysis oil; gasification; drop-in; energy systems; techno-economic; Energiteknik; Energy Engineering;

    Abstract : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. READ MORE

    Abstract : The strive towards more fuel efficient ships is a continuously ongoing process, motivated by both economic and regulatory reasons. An important aspects to consider for the final fuel consumption is the propulsion system performance in relevant operating conditions. READ MORE

  7. 5. Dietary energy density and energy intake in cancer patients

    Author : Ola Wallengren; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cachexia; diagnostic criteria; quality of life; nutritional support; energy intake; energy balance; dietary energy density;

    Abstract : Background & Aims: Cachexia is frequent in advanced cancer and is associated with adverse outcomes; however, definite diagnostic criteria for cachexia are not established. Diet energy density (ED) may affect energy intake (EI) and energy balance. Patient characteristics may also influence such associations. READ MORE
