  1. 1. Cascading extinctions in food webs : local and regional processes

    University dissertation from Linköping : Linköpings universitet

    Author : Anna Eklöf; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cascading extinctions; complexity; connectance; dispersal; food web; local dynamics; regional dynamics; resistance; spatial structure; species loss;

    Abstract : Ecological communities all over the world are loosing biodiversity due to different kinds of human activities and there is an urgent need of understanding how those losses affect the function of the ecosystems on which we all depend. The community's response to species losses is likely to depend on both the structure of the local community as well as its interactions with surrounding communities. READ MORE

  2. 2. Marketing Progress and Buyer Behavior in the Middle East : A deep structure approach

    University dissertation from Linköping : Linköpings universitet

    Abstract : This report is an extension of deep structure "socio-cultural" approach ininternational marketing by:1- Developing methodological and conceptual tools for understanding socio-cultural characteristic of the Middle - East nations, example of Saudi Arabia; buyer behavior and buyer seller relationship.2- Interprating buyers actions, decision making process, imoressions ,etc. READ MORE

  3. 3. Species interactions and community structure

    University dissertation from Peter Frodin, Department of Theoretical Ecology, Ecology Building, S-223 62 Lund, Sweden

    Author : Peter Frodin; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; spatial structure; local stability; enrichment; species interactions; Community structure; population dynamics;

    Abstract : In this theses I have focused on how the mechanisms of species interactions affect community structure. It is well known that certain species may have a particularly strong influence on the structure of a community. What is not fully understood is how to characterize these species that have such a strong impact on community structure. READ MORE

  4. 4. Resin transfer moulded composite materials : processing, structure, property relationships

    University dissertation from Luleå : Luleå tekniska universitet

    Author : J. Anders Holmberg; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : This thesis contains analysis of the performance of polymer composites manufactured by resin transfer moulding (RTM). The thesis consists of six papers, where the first two deals with the tensile strength of composites reinforced with randomly oriented glass fibres, which still is the most common reinforcement in RTM manufacturing.

  5. 5. Wood fiber composites : processing, structure and properties

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lars-Olof Nordin; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : The goal of this work has been to investigate how to make wood polymer composite materials with good mechanical properties, which also could be tailored for different applications. The fundamental idea behind the work was that good mechanical properties of the composite material require that the stiffness and strength of the wood cell wall material are really utilized. READ MORE
