2. 1. Energy systems studied of biogas : Generation aspects of renewable vehicle fuels in the transport system

   Author : Mimmi Magnusson; Per Alvfors; Umberto Desideri; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; biogas; biomass; energy system; first-generation biofuels; renewable vehicle fuels; second-generation biofuels; supply- and demand-side measures; third-generation biofuels; transport system;

   Abstract : The transport sector is seen as particularly problematic when concerns about climate change and dependency on fossil energy are discussed. Because of this, bioenergy is strongly promoted for use in the transport sector, both on a European level and nationally in Sweden. READ MORE

4. 2. Language maintenance or shift? : a study of Greek background students in Sweden

   Author : Nelly Kostoulas-Makrakis; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Tvåspråkighet Sverige; Grekiska språket; Svenska språket; Etnolingvistik; Greker-- Sverige; Invandrarungdomar-- Sverige; Invandrarbarn-- Sverige; Hemspråksundervisning-- Sverige;

   Abstract : This study explores and illustrates the process of language maintenance and shift among greek background students in Sweden, who attend home language instruction. The results show that students' attitudes learning greek were positive. The great majority of students indicated a strong in-group identification. READ MORE

5. 3. Generational Use of News Media in Estonia : Media Access, Spatial Orientations and Discursive Characteristics of the News Media

   Author : Signe Opermann; Göran Bolin; Cecilia von Feilitzen; Cristina Ponte; Södertörns högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; generation; media use; media repertoires; media landscapes; news consumption; age; life course; social space; Estonia; Kritisk kulturteori; Critical and Cultural Theory; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Abstract : Contemporary media research highlights the importance of empirically analysing the relationships between media and age, changing user patterns over the life course, and generational experiences within media discourse beyond the widely hyped buzz terms such as the ‘digital natives’, ‘Google generation’, and other digitally and technologically capable generation groups. This doctoral thesis seeks to define the ‘repertoires’ of news media that different generations use to obtain topical information and create their ‘media space’. READ MORE

6. 4. Polymer light-emitting electrochemical cells : Utilizing doping for generation of light

   Author : Piotr Matyba; Ludvig Edman; Qibing Pei; Umeå universitet; []
   Keywords : ;

   Abstract :     The current implementation of conjugated polymers (“conducting plastics”) in a wide range of devices promises to bring the vision of a new generation of flexible, efficient and low-cost applications to reality. Plastic lightemitting devices in the form of polymer light-emitting diodes (PLEDs) are projected to be particularly close to the market in applications such as large area and conformable illumination panels and high-performance thin displays.

7. 5. Biogas generation in landfills : equilibria, rates & yields

   Author : Mattias Åkesson; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; model; limitation; volatile fatty acids; kinetics; biogas; thermodynamics; methane; Landfill; test cell; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

   Abstract : Landfilling in "cells" has become more common in recent years. Different waste streams are guided to different cells, among which the biocell is a landfill designed for biogas production. In this thesis, the dependence of biogas generation on waste composition was investigated. READ MORE
