1. 21. Lokalradio och kommersiell radio 1975−2010 : En mediehistorisk studie av produktion och konkurrens

   Författare :Michael Forsman; Madeleine Kleberg; Per Jauert; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; radio history; competition; intermedial; intramedial; media production; media politics; local radio; commercial radio; branding; formatting; scheduling; Media and communication studies; Medie- och kommunikationsvetenskap; medie- och kommunikationsvetenskap; Communication Studies; Other research area;

   Sammanfattning : The main question in this dissertation is: How can the emergence of local and commercial radio and the ensuing changes within each be understood in relation to intermedial and intramedial competition? This overarching question is broken down into four research questions. What driving forces contributed to the implementation of local and commercial radio respectively? (How can the competitive context of these two radio forms be described and periodized? In what ways have the practices of producing radio output, radio audiences and brands changed during the period covered by this study? What similarities and differences have emerged between local radio and commercial radio over time? This study can be seen as an institutional media history, focusing on two distinctive periods in the history of Swedish radio and television, Decentralization (1977-1987) and Commercialization (1987 onwards).

3. 22. Sensory Dynamics in Emulsion Products Differing in Fat Content

   Författare :Karin Wendin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; smell; texture; rheology; flavour; fat content; taste; sensory analysis; time intensity; ordinary differential equation; polynomial; emulsion products;

   Sammanfattning : Flavour, taste and texture are important qualities when purchasing food and the richness and smoothness of fat are desired properties for many individuals. However, fat is the major nutrition concern of many consumers. It is therefore important to be able to produce attractive products containing low amounts of fat. LÄS MER

4. 23. Sludge from pulp and paper mills for biogas production : Strategies to improve energy performance in wastewater treatment and sludge management

   Författare :Alina Hagelqvist; Thomas Nilsson; Karin M. Granström; Bengt Månsson; Bo Mattiasson; Thomas Welander; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; pulp and paper mill sludge; methane production; energy efficient sludge management; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : The production of pulp and paper is associated with the generation of large quantities of wastewater that has to be purified to avoid severe pollution of the environment. Wastewater purification in pulp and paper mills combines sedimentation, biological treatment, chemical precipitation, flotation and anaerobic treatment, and the specific combination of techniques is determined by the local conditions.

5. 24. Conversion processes for biofuel production

   Författare :Jerry Luis Solis; Yohannes Kiros; Mohammad Taherzadeh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Second-generation biofuels; biodiesel; heterogeneous catalysts; non-edible oils; ethanol; residual biomass; native yeast strains.; Andra generationens biobränslen; biodiesel; heterogena katalysatorer; oätliga oljor; etanol; rester av biomassa; naturliga jäststammar; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

   Sammanfattning : Despite the global positive impacts of soybean-, maize- and sugarcane-based (first-generation) liquid biofuels, several drawbacks pertaining to increased use of agricultural land, causing deforestation in some countries and extensive practice of fertilizers have been observed. As a result, developing advanced (second- and third-generation) liquid biofuels have been identified as better alternatives and are considered to be of great importance in the future. LÄS MER

7. 25. Utilizing CO2 from biomethane production : Sustainability and climate performance

   Författare :Stephanie S. Cordova; Mats Eklund; Marcus Gustafsson; Niclas Svensson; Valentina Bisinella; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomethane; Carbon capture and utilization; CCU; CO₂ utilization;

   Sammanfattning : Biogas solutions offer many benefits for the environment and society, including organic waste treatment as well as being an enabler for energy and nutrient recovery. The products of anaerobic digestion are a biogas, which contains a share of 30 to 50% carbon dioxide (CO2) and 50 to 70% methane, and a liquid remanent, rich in nutrients. LÄS MER
