  2. 16. Assessing design strategies for improved life cycle environmental performance of vehicles

    Author : Sofia Poulikidou; Anna Björklund; Per Wennhage; Gregory Keoleian; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle design; Design strategies; Lightweight design; Electric vehicles; Design for Environment DfE ; DfE tools; Life cycle assessment LCA ; Simplified LCA; Composite materials; Planering och beslutsanalys; Planning and Decision Analysis;

    Abstract : Vehicle manufactures have adopted different strategies for improving the environmental performance of their fleet including lightweight design and alternative drivetrains such as EVs. Both strategies reduce energy during use but may result in a relative increase of the impact during other stages. READ MORE

  4. 17. Lake sediment as environmental archive : natural and anthropogenic influence on the chronology of trace elements

    Author : Evastina Grahn; Stefan Karlsson; Anders Düker; Bo Bergbäck; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lake sediment; environmental pollution; trace elements; chronology; diagenesis; Ag; Be; Ga; In; Pb; Sb; Tl; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Abstract : The focus of this thesis is the historical pollution of some seldom-monitored trace elements (SMTEs; Ag, Be, Ga, In, Sb and Tl) that have been involuntarily released for several thousands of years but whose usage have increased during the industrial era. Sediment cores from four rural lakes in a south to north transect in central Sweden, and two urban lakes have been used as environmental archives for chronological studies. READ MORE

    Abstract : The Swedish Road Administration (SRA) is responsible for maintenance of the state-run roads in Sweden. The SRA also has an overarching responsibility for the state of the environment in the road transport sector. READ MORE

  6. 19. Conjoint analysis as a tool for communication and corporate environmental decision-making

    Author : Stina Alriksson; Tomas Öberg; Marianne Lindström; Högskolan i Kalmar; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conjoint analysis; PLS; Cluster analysis; Communication; Environmental; Decision-making; Environmental engineering; Miljöteknik; Miljövetenskap; Environmental Science;

    Abstract : Conjoint analysis has been used extensively in marketing, transportation and healthcare for the past 50 years. Since the mid-1990s, it has also been applied to an increasing number of environmental issues. In this thesis, conjoint analysis is applied to environmental objectives of the Swedish steel industry.

  7. 20. Factors influencing emission fluxes and bacterial enrichment in sea spray aerosols : Insights from laboratory and field studies

    Author : Julika Zinke; Matthew E. Salter; Paul Zieger; Rachel A. Foster; E. Douglas Nilsson; Patricia K. Quinn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sea spray aerosols; eddy covariance fluxes; air-sea-exchange; bacteria; primary biological airborne particles; laboratory studies; field studies; Baltic Sea; North-Eastern Atlantic; Environmental Sciences; miljövetenskap;

    Abstract : Sea spray aerosol (SSA) is one of the major natural aerosol sources and is produced when wave breaking entrains air into ocean surface water, which subsequently breaks up into bubbles. These bubbles rise to the surface and can scavenge biogenic material. READ MORE
