1. 21. Characterisation of PFASs and Organofluorine in Freshwater Environments : Transfer from water to land via emergent aquatic insects

   Författare :Alina Koch; Thanh Wang; Micael Jonsson; Leo W. Y. Yeung; Anna Kärrman; Lutz Ahrens; Jonathan Martin; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFASs; riparian zone; emergent aquatic insects; terrestrial consumers; stable isotopes; organofluorine mass balance; AFFF; point sources;

   Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are anthropogenic contaminants of emerging concern, because many are highly persistent to degradation and have been linked to adverse effects in humans as well as their ubiquitous spread in aquatic environments. This thesis investigated distribution of PFASs and organofluorine in freshwater environments impacted by PFAS point sources. LÄS MER

3. 22. Microeconomic Policy for Development: Essays on Trade and Environment, Poverty and Education

   Författare :Miguel Quiroga; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; absenteeism; aggregation bias; comparative advantage; decomposition analysis; education; environmental endowment; environmental regulation; factor content; geography; hyperbolic discounting; living standards; mandatory attendance; non-homothetic preferences; pollution haven; Porter hypothesis; poverty; present-biased preferences; teaching; time-inconsistent preferences; trade;

   Sammanfattning : Abstracts This thesis contains three papers analyzing different issues. Paper 1: “Do Countries with Lax Environmental Regulations Have a Comparative Advantage in Polluting Industries?” We study whether lax environmental regulations induce comparative advantages, causing the least-regulated countries to specialize in polluting industries.

4. 23. A Comprehensive Approach to Modeling and Control of Thermomechanical Pulping Processes

   Författare :Daniel Berg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The central issue of the thesis is modeling and control of the Thermomechanical Pulp (TMP) process in which large refiners are used to produce pulp for newsprint. The TMP process is one of the most complex and versatile, electricity consuming industrial processes today. LÄS MER

5. 24. Baltic Sea sediments : Source and sink for metal contamination

   Författare :Sina Shahabi-Ghahfarokhi; João Marcelo Ketzer; Alessandro Amorosi; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Baltic Sea; sediments; acid sulfate soil; metal; remediation; reoxygenation; X-ray absorption spectroscopy; Environmental Chemistry; Miljökemi; Miljövetenskap; Environmental Science;

   Sammanfattning : The Baltic Sea sediments record spatial and temporal information about metalsand metalloids (hereafter referred to as metals), which could help to understandthe past and present contamination sinks in different basins. In addition, giventhe expanding anoxic zones in the Baltic Sea, the response of metals to artificialreoxygenation is poorly understood. LÄS MER

7. 25. Distributed engineering : tools and methods for collaborative product development

   Författare :Peter Törlind; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Funktionella produkter; Functional Product Development;

   Sammanfattning : Engineering design is fundamentally social, requiring much interaction and communication between the people involved. Additionally, good design often relies upon the ability of a cross-functional team to create a shared understanding of the task, the process, and the respective roles of its members. LÄS MER
