1. 11. Mechanical and Environmental Durability of High Performance Bio-based Composites

   Författare :Newsha Doroudgarian; Egidija Rainosalo; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Sammanfattning : This study is an initial step within the on-going project on development of high performance bio-based composites with improved mechanical (fatigue) and environmental (elevated humidity and temperature) durability. In the presented thesis the performance of cellulosic fibers (flax and regenerated cellulose), bio-based resins (Tribest, EpoBioX, Palapreg, and Envirez) and their composites under exposure to elevated humidity has been studied.

3. 12. Acquisition of Capabilitities through International Technology Transfer

   Författare :Sverker Alänge; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industrialization; Technology transfer; Network; Entrepreneurship; Industrial economics; Innovation; Diffusion; Developing countries; Infant industry; Motivation;

   Sammanfattning : The focus in this thesis is on the acquisition of static and dynamic capabilities in LDC industry. This has been studied in small industries in Tanzania, which were started through international technology transfer, in which small producing firms from Sweden acted as technology suppliers (The Sister Industry Programme).

4. 13. DIFFUSION OF IONS IN WOOD

   Författare :Reddysuresh Kolavali; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium chloride; impregnation; diffusion; Norway spruce; local concentration profiles; experimental methodology; micro-cracks; wood; Donnan effect;

   Sammanfattning : Wood sourced from well managed plantations or forests, is a renewable material with many advantages over non-renewable (fossil) material, and also wood lignocelluloses are the only type of biomass that is a seasonal-independent product. In addition to direct utilization as a building material, major uses of wood are currently for making pulp and paper products, and fuel. LÄS MER

5. 14. General purpose technology diffusion and labour market dynamics : A spatio-temporal perspective

   Författare :Mikhail Martynovich; Institutionen för kulturgeografi och ekonomisk geografi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; general purpose technology; technological change; information technology; IT; diffusion; labour market dynamics; labour mobility; worker reallocation; Sweden;

   Sammanfattning : This dissertation aims at advancing the knowledge about the role of the labour market in the process of the technology-induced economic transformation, taking into account the variety of factors involved at micro-, meso-, and macro-levels of the economy and at different geographical scales. Empirically, the dissertation investigates the co-evolutionary dynamics of industrial restructuring and worker reallocation across and within regional labour markets induced by the diffusion of the information technology as a general purpose technology (GPT) in Sweden in the period between 1985 and 2010.

7. 15. Modeling of Hindered Diffusion in Gels

   Författare :Jan Gutenwik; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; effective diffusion coefficient; pore size distribution; obstruction; immobilization; modeling; adsorption kinetics; hindered diffusion; simulation program; proteins; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Sammanfattning : Hindered diffusion occurs in the most different processes, as has been described in this thesis. It is very important to have an understanding of the influence of hindered diffusion on the mass transfer rate, especially when competing rate processes are acting simultaneously. LÄS MER
