  1. 1. Payback Time : Essays on Attitudes, Partiality, and Rescuing

    Author : Romy Eskens; Helen Frowe; Gunnar Björnsson; R. Jay Wallace; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; ethics; moral philosophy; reactive attitudes; gratitude; supererogation; beneficence; wrongdoing; equality; partiality; duties to rescue; Philosophy; filosofi;

    Abstract : Does the moral quality of someone’s past treatment of us, or of other people, change how we are morally permitted or required to treat them? Many philosophers think so. They argue, for instance, that someone’s supererogatory or impermissible behaviour can permit or require certain positive or negative attitudinal responses, such as gratitude or resentment.

    Abstract : Energy use in the European Union is increasing. At the same time, it is estimated that by the year 2050 most of the EU population will be living in currently existing buildings. Some of these buildings are or will be in need of renovation, and they have identified a target to reduce overall energy use. READ MORE

  3. 3. Process Integration of Industrial Heat Pumps in Grass-Root and Retrofit Situations

    Author : Erik Wallin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; pinch technology; retrofit; industrial heat pumps; grass-root;

    Abstract : In several works, methods for process integration of heat pumps (HPs) have been developed, which in turn have been used for case studies in different industrial types. HP integration has thus proven to be a promising technique for utility savings and attractive payback periods. READ MORE

  4. 4. Industrial Bioprocess Developments for Biogas and Ethanol Production

    Author : Karthik Rajendran; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; ethanol; process design; techno-economic analysis; simulation; modeling; Resource Recovery; Resursåtervinning;

    Abstract : Current biofuels face a noteworthy misfortune on commercialization because of its economiccomparison with low-cost fuel from the oil reserves. To compete with gasoline as a fuel, thebiofuels need to be economically feasible and demonstrated on a large-scale. READ MORE

  5. 5. Energy Analysis of the Closed Greenhouse Concept : Towards a Sustainable Energy Pathway

    Author : Amir Vadiee; Viktoria Martin; Halime Paksoy; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; closed greenhouse; energy analysis; energy management; SRA - Energy; SRA - Energi;

    Abstract : The closed greenhouse is an innovative concept in sustainable energy management. The closed greenhouse can be considered as a large commercial solar building. In principle, it is designed to maximize the utilization of solar energy through seasonal storage. In a fully closed greenhouse, there are not any ventilation windows. READ MORE
