    Författare :Tomas Johansson; Luleå tekniska universitet.; [2006]
    Nyckelord :Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : Wireless ad-hoc networks differs in many aspects compared to traditional infrastructured networks. Among other things, individual nodes cannot be expected to know the topology of the entire network. LÄS MER

  2. 2. Habitat selection, nest predation and conservation biology in a Black-tailed Godwit (Limosa limosa) population

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Tomas Johansson; Uppsala universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Black-tailed godwit; Limosa limosa; nest site selection; nest predation; philopatry; risk analysis; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; populationsbiologi; Population Biology;

    Sammanfattning : This thesis focuses on a black-tailed godwit (Limosa limosa) population, consisting of 35-40 pairs, that breeds on a grazed shore meadow on SE Gotland, Sweden. The small size of the population makes it more prone to extinction due to chance events, than a larger population.The godwits showed microhabitat preferences when choosing nest sites. LÄS MER

    Sammanfattning : The national curriculum and the School Act emphasize the importance of establishing partnerships between schools and local businesses. The formation of partnerships was expected to be facilitated by the decentralization reforms that took place in the beginning of the 1990’s. LÄS MER

  5. 5. Structure Analysis of a Transient Protein Complex - NMR, X-ray crystallographic and Mass Spectrometric Studies of the Soluble Domains of the Proton-Pump Transhydrogenase from E. coli

    Detta är en avhandling från Chalmers University of Technology

    Författare :Tomas Johansson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Bioengineering; proton-translocating transhydrogenase; structure; nuclear magnetic resonance; x-ray crystallography; interactions;

    Sammanfattning : Interactions between macromolecules in the cell are fundamental to life. However, many interactions are of a transient nature and are as such difficult to study at the atomic level using existing techniques. LÄS MER
