1. 6. Mineralogical, chemical and textural properties of the Malmberget iron deposit : a process mineralogically characterisation

   Författare :Cecilia Lund; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

   Sammanfattning : This thesis combine two different but closely connected disciplines in a mining process to each other, ore geology and process mineralogy by studying mineralogical-textural features of the ore and the ore concentrate in an apatite iron ore deposit in Malmberget, Sweden. Apatite iron ore deposits (Kiruna type) exist in a few places around the world and the two most important deposits are mined by LKAB at Kiruna and Malmberget. LÄS MER

3. 7. Terahertz sensing for non-destructive characterisation of pharmaceutical tablets

   Författare :Anis Moradikouchi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensing.; non-destructive; pharmaceutical tablets; Terahertz technology; frequency domain; dielectric characterisation; porosity measurements;

   Sammanfattning : The pharmaceutical industry is shifting from conventional batch manufacturing to continuous manufacturing. To realise continuous manufacturing, it is crucial to assess the product quality of tablets at different stages of the production line. LÄS MER

4. 8. Food Web Ecology -- individual life-histories and ecological processes shape complex communities

   Författare :Martin Hartvig; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; food web; community ecology; community assembly; size-structure; life-history omnivory; ontogeny; trophic interactions; trait based model; topology; emergent organisation; size-spectrum;

   Sammanfattning : This thesis sets out a food web framework for size-structured populations. The framework enables an ecological approach to food web modelling as the individual life-history from birth, through maturation, and ultimately death is explicitly resolved with the use of bioenergetics based on individual body size.

5. 9. Nanocellulose for Biomedical Applications : Modification, Characterisation and Biocompatibility Studies

   Författare :Kai Hua; Natalia Ferraz; Maria Strømme; Albert Mihranyan; Pedro Granja; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocellulose; nanofibrillated cellulose; Cladophora cellulose; biocompatibility; inflammation; surface modification; surface group density; surface topography; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Sammanfattning : In the past decade there has been increasing interest in exploring the use of nanocellulose in medicine. However, the influence of the physicochemical properties of nanocellulose on the material´s biocompatibility has not been fully investigated. LÄS MER

7. 10. Optical Characterisation of Miniature Structures and Translucent Sheets for Daylighting Applications

   Författare :Jacob Jonsson; Arne Roos; Helen Rose-Wilson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Photospectrometry; Light scattering; Optical characterisation; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : For a long time spectrophotometry has been a powerful method of determining optical material properties. Since the technique measures the parameters of interest, reflectance and transmittance, it is in general easy to use and interpret. LÄS MER
