1. 1. Den televiserade politiken : studier av debatt- och nyhetsjournalistik

   Författare :Göran Eriksson; Mats Ekström; Stig- Arne Nohrstedt; Klaus Bruhn Jensen; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mediazation of politics; mediated political discourse; television journalism; critical discourse analysis; an integrated approach; ethnographic methods; case studies; medie- och kommunikationsvetenskap; Media and communication studies; Medie- och kommunikationsvetenskap; Media and Communication Studies; Medie- och kommunikationsvetenskap;

   Sammanfattning : This study takes as its point of departure the discussion around the mediazation of politics. The media are an essential part of, and play a crucial role for, the reproduction of a certain discourse that, within the field of Media and Communications research, has been branded a mediated or mediatized political discourse (Fairclough 1995a; Chouliaraki 2000; Ekström 2001 Ib).

3. 2. Evaluating Cathode Catalysts in the Polymer Electrolyte Fuel Cell

   Författare :Henrik Ekström; Göran Lindbergh; Anders Lundblad; Anthony Kucernak; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fuel cell; humidity; model electrodes; Nafion; oxygen reduction; PEMFC; platinum; polymer electrolyte; thin film evaporation; titanium oxide; bränslecell; fuktighet; modellelektroder; Nafion; PEMFC; platina; polymerelektrolyt; syrereduktion; tunnfilmsförångning; titanoxid; Electrochemistry; Elektrokemi;

   Sammanfattning : The polymer electrolyte membrane fuel cell (PEMFC) converts the chemical energy of hydrogen and oxygen (air) into usable electrical energy. At the cathode (the positive electrode), a considerable amount of platinum is generally required to catalyse the sluggish oxygen reduction reaction (ORR). LÄS MER

4. 3. The dynamic behavior of the NiMH battery – Creating a versatile NiMH battery model

   Författare :Jenny Börjesson Axén; Göran Lindbergh; Henrik Ekström; Erika Widenkvist Zetterström; Paul Albertus; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NiMH batteries; Battery Modeling; OCV hysteresis; NiMH gas phase; P2D model; NiMH batterier; Batterimodellering; OCV hysteres; NiMH gasfas; P2D modell; Chemical Engineering; Kemiteknik;

   Sammanfattning : To facilitate the shift from fossil to renewable energy sources, energy storage is needed to cope with the intermittent nature of technologies such as solar, wind, and wave power. One storage alternative is battery-based stationary energy storage. LÄS MER

5. 4. Öppenhetsindustrin

   Författare :Peter Jakobsson; Göran Bolin; Mats Ekström; Bo Reimer; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; copyright; creative industries; the openness industry; governmentality; ideology; EU; Youtube; CCIA; crowdsourcing; Media and Communication Studies; Medie- och kommunikationsvetenskap;

   Sammanfattning : Over recent decades several competing descriptions of the media and cultural industries have been put forward. The media and cultural industries have been described as creative industries, copyright industries, and as constitutive of an experience economy. LÄS MER

7. 5. Studies of Unusual Seismicity and Long Period Events at the Glacier Overlain Katla Volcano, Iceland

   Författare :Kristín Jónsdóttir; Roland Roberts; Björn Lund; Göran Ekström; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Geofysik; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Sammanfattning : Earthquake catalogues are usually dominated by diffusive behaviour consistent with the Omori law of aftershocks. This is investigated in terms of waiting times, i.e. the time between successive events in a time-sorted earthquake catalogue. LÄS MER
