  2. 1. Urbanised Nature in the Past : Site formation and Environmental Developement in Two Swedish Towns, AD 1200-1800

    Author : Jens Heimdahl; Ann-Marie Robertsson; Jane Sidell; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Urban stratigraphy; environmental reconstruction; site formation; geoarchaeology; dark earth; macrofossil analysis; Quaternary geology; Kvartärgeologi;

    Abstract : In order to explore site formations and reconstruct environmental development in Medieval and Post-Medieval towns, urban occupational strata in Norrköping and Karlstad were studied according to biostratigraphy, sedimentology and pedology. New field procedures including continuous pilot sampling, parallel archaeological and geological stratigraphic interpretation, and on-site analysis of plant macrofossils were developed and applied at archaeological excavations in both towns.

  4. 2. Out of Site : Landscape and Cultural Reflexivity in New Hollywood Cinema 1969-1974

    Author : Henrik Gustafsson; Astrid Söderbergh Widding; Asbjørn Grønstad; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; cultural identity; film analysis; film and nation; genre revisionism; intermediality; landscape in art; landscape in cinema; New Hollywood; new realism; nostalgia film; reflexivity; road movies; Film; Filmvetenskap; Cinema Studies; filmvetenskap;

    Abstract : This dissertation examines landscape as a concept for analysis and interpretation in film studies by considering the New Hollywood cinema in the late 1960s and early 1970s. Contextualized within the contested notion of nationhood at the time as well as the concern among filmmakers to probe the properties, practices and traditions of American cinema, this was also a period when landscape underwent widespread redefinition as a field of artistic and academic practice.

  5. 3. Guidance and Control for Multiple Spacecraft Formation

    Author : Sumeet Gajanan Satpute; George Nikolakopoulos; Per Bodin; Kazuya Yoshida; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spacecraft Formation; Concurrent maneuver planning; Co-location; Geostationary satellite; Asteroid visual coverage; Trajectory planning; Traveling salesman problem; Onboard space systems; Rymdtekniska system;

    Abstract : Multiple spacecraft formation forms a distributed space system where multiple spacecraft cooperatively exhibit the functionality of a single monolithic spacecraft or work in a cooperative way towards the completion of a common goal. This possibility of distributing the workload between different spacecraft provides the ability to work in parallel, enable economic and simple solutions in terms of spacecraft design, while is redundant towards partial or complete failure of a spacecraft.

  6. 4. BMP implants in bone formation. Studies in rabbits and rats

    Author : Charlotte Jeppsson; Malmö Handkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ortopedi; traumatologi; graft resorption.; Kirurgi; Surgery; orthopaedics; traumatology; bone formation; bone graft; hydroxyapatite; collagen; bisphosphonate; rat; rabbit; titanium chamber; BMP; TGF-ß;

    Abstract : Bone morphogenic proteins, BMPs, are a group endogenous proteins that are highly conserved through evolution. The amino acid sequences of about 15 different BMPs are now known and recombinant human BMPs are commercially available. Implantation of an individual BMP protein is sufficient to induce bone formation even at a subcutaneous site. READ MORE

  7. 5. Heme-copper oxidases and nitric oxide : Reaction mechanisms and supercomplex formation

    Author : Ingrid Albertsson; Pia Ädelroth; Alessandro Giuffrè; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heme-copper oxidase; nitrite reductase; nitric oxide reductase; nitric oxide; supercomplex; Paracoccus denitrificans; denitrification pathway; proton transfer pathway; C-type oxidase; Helicobacter pylori; Biochemistry; biokemi;

    Abstract : In the denitrification process where nitrate is stepwise reduced to nitrogen gas, the toxic molecule nitric oxide (NO) is formed as an intermediate. Nitric oxide is produced by the enzyme cd1 Nitrite reductase (cd1NiR) by reduction of nitrite and is later reduced to nitrous oxide by nitric oxide reductase (cNOR). READ MORE
