   Sammanfattning : This thesis is comprised of four studies and concerns haemodialysis patients’ confidence in being able to manage fluid intake between treatment sessions, and whether the fluid intake is influenced by certain modifiable characteristics of the persons in question. The overall aim was to study aspects of excessive fluid overload and haemodialysis patients’ self-regulation of fluid allotment from a bio-psychosocial and behavioural medicine perspective. LÄS MER

3. 7. Fluid flow in wood fiber network

   Författare :Patrik Pettersson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : Cellulose material is processed to pulp suspensions and MDF boards in order to produce products such as papers, magazines, laminate floors or door skins. A critical stage of these processes is when the cellulose fiber networks are compressed to specific densities and when most of the fluid originally positioned between and inside the fibers is forced to leave the network.

4. 8. Pressurized Fluid Extraction : A Sustainable Technique with Added Values

   Författare :Monica Waldebäck; Karin Markides; Åke Bergman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; ASE; biomass; green chemistry; household waste; lipid; pesticide; PFE; pressurized fluid extraction; sediment; Analytisk kemi; Analytical chemistry; Analytisk kemi;

   Sammanfattning : The challenge for the future was defined by the Brundtland Commission (1987) and by the Rio Declaration (1992), in which the fundamental principles for achieving a sustainable development were provided. Sustainable chemistry can be defined as the contribution of chemistry to the implementation of the Rio Declaration. LÄS MER

5. 9. Miniaturized fluid system for high-pressure analytics

   Författare :Simon Södergren; Klas Hjort; Sami Franssila; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-pressure; Microfluidics; Thermal regulation; Fluid mechanics; In-situ sensors; High-pressure analytics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

   Sammanfattning : High-pressure chemistry can be used to determine the contents of blood or water samples and to discover new chemistries. However, working with chemistry at pressures of many tens, or even hundreds, of bars often requires expensive and stationary equipment, such as autoclaves or chromatographic systems like high-performance liquid chromatography (HPLC).

7. 10. Internal erosion in embankment dams : fluid flow through and deformation of porous media

   Författare :J. Gunnar I. Hellström; Thanasis D. Papathanasiou; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : A basic understanding of fluid flow through a porous media facilitates a comprehensive understanding of internal erosion in embankment dams. Hence, it is necessary to reveal the detailed seepage flow, the flow-induced forces acting within the porous media and the fluid flow deformation of the porous media. LÄS MER
