2. 1. High (valent) on O2 : Ribonucleotide Reductase and Methane Monooxygenase

   Author : Juliane John; Martin Högbom; Pål Stenmark; Peter Moody; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribonucleotide Reductase; Methane Monooxygenase; biokemi; Biochemistry;

   Abstract : Macromolecular X-ray crystallography (MX) is a powerful method to investigate protein structures. However, proteins with redox-active centres and radicals are very susceptible to photoreduction. READ MORE

4. 2. Structural sound transmission and attenuation in lightweight structures

   Author : Lars-Göran Sjökvist; RISE; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sound insulation; acoustics; wooden houses; Fourier transform; lightweight building; stiffened plate; junction; stiffeners; flanking transmission; attenuation;

   Abstract : Everyone wants a peaceful and quiet home, but in noisy cities it is a challenge to create such homes. New building techniques are mostly introduced for other purposes than noise control -- stability, economy, heat transfer and so on. READ MORE

5. 3. Miniaturized Hard Waveguides in Multifunction Array Antennas

   Author : Malcolm Ng Mou Kehn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interlaced arrays; Floquet theorem; reflector antennas; focal plane array; multifunction antennas; miniaturized waveguides; multilayer structures; spectral domain technique; periodic structures; aperture reuse; method of moments; soft and hard surfaces; array antennas;

   Abstract : Recent advances in technologies of wireless communications systems have led to an increasing desire for several antennas performing diverse functions at different frequencies to be integrated into a common radiating aperture. This gives rise to the so-called multifunction antenna, which affords the saving of scarce premium real estate and can alleviate problems arising from excessive antenna protrusions in aspects such as aerodynamics, aesthetics, and stealth capability in military applications.

6. 4. Numerical Model of Beach Topography Evolution due to Waves and Currents: Special Emphasis on Coastal Structures

   Author : Thanh Nam Pham; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; morphodynamics; surface roller; wave-induced currents; random waves; sediment transport; coastal structures;

   Abstract : The beach topography change in the nearshore zone may be induced by natural phenomena such as wind, wave, storm, tsunami, and sea level rise. However, it can also be caused by man-made structures and activities, for example, groins, detached breakwaters, seawalls, dredging, and beach nourishment. READ MORE

7. 5. Dialogues on the Net - Power structures in asynchronous discussions in the context of a web based teacher training course

   Author : Annette Johnsson; Utbildningsvetenskap; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; minority; cultural background; sex; ethnicity; gender; age; socio-economic; dialogicity; web based; computer based; CMC; net based; asynchronous; CSCL; teacher education; power structures; dialogues; Group work; team work; symbolic capital; group work;

   Abstract : The general aim of this thesis is to investigate the interaction processes that occur in group dialogues when teacher students work in small groups, using net based asynchronous dialogues to solve a problem in the area of environmental sustainability. More specifically, the interest is to determine whether students’ net based dialogues give rise to patterns of dominance/subordination similar to those observed in face-to-face situations. READ MORE
