  1. 1. Workplace Ethics : Some practical and foundational problems

    Författare :Anders J Persson; Sven Ove Hansson; Matti Häyry; Anders Persson; KTH; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Philosophy; Ethics; contract of employment; ethics; ethical criteria; health and safety standards; Philosophy subjects; Filosofiämnen; Philosophy; Filosofi;

    Sammanfattning : The aim of the present thesis is twofold: first, to analyse some practical ethical problems that stem from the workplace and the working environment and to offer guidelines concerning how such problems can be solved; second, to illuminate how the specific nature of work and the working environment is intimately connected to the relation between the employee and the employing entity, as set forth in an employment contract, and how the form and content of such contracts are, among other things, determined by culturally and socially established ideas. The normative question to be addressed is thus: which of these ideas should be maintained? This can be seen as a second-order, or more fundamental, ethical question whose answer depends on determining which normative principles are right. LÄS MER

  3. 3. Bimetallic Palladium Catalysts for Methane Combustion in Gas Turbines

    Författare :Katarina Persson; Sven Järås; Jon McCarty; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; activity; bimetal; catalytic combustion; DRIFTS; EDS; gas turbine; methane; morphology; palladium; platinum; pressure; PXRD; stability; TEM; TPO; XPS; Chemical engineering; Kemiteknik;

    Sammanfattning : Catalytic combustion is a promising combustion technology for gas turbines, which results in ultra low emission levels of nitrogen oxides (NOx), carbon monoxide (CO) and unburned hydrocarbons (UHC). Due to the low temperature achieved in catalytic combustion almost no thermal NOx is formed. LÄS MER

  4. 4. Evaporation and Heat-flux Aggregation in Heterogeneous Boreal Landscapes

    Författare :Tony Persson; Sven Halldin; Dimitris Melas; Deliang Chen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Hydrology; land-surface processes; heterogeneity; surface fluxes; soil-water content; high latitudes; snow; lakes; climate; mesoscale model; NOPEX; WINTEX; Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : The boreal forests represent 8 % of all forested areas on the earth and have a significant role in the control of greenhouse gases and an impact on global climate change. The main objective of this thesis is to increase the understanding of how evaporation and heat-flux processes in the boreal forest zone are affecting the regional and global climate. LÄS MER

  5. 5. District heating in future Europe : Modelling expansion potentials and mapping heat synergy regions

    Författare :Urban Persson; Sven Werner; Lars J. Nilsson; Chalmers University of Technology; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; district heating; energy efficiency; distribution capital cost; heat demand density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation rate; effective width;

    Sammanfattning : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.
