  2. 1. Fluid flow in wood fiber network

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

    Abstract : 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.

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

    Abstract : Cellulose-based commercial items such as paper and laminated flooring are vital to the local economy of northern Sweden. These products are commonly manufactured in suspension where fluids such as water or air are drained through the fiber network in some value-added steps in the manufacturing process. READ MORE

Beardsley; fraudulence; modernism; escape to theory; Literature; Litteraturvetenskap;

    Abstract : This dissertation explores and analyzes interpretive skepticism in literary theory. It argues that traditional interpretive theories and debates often harbor unacknowledged forms of skeptical thinking and arguments. As these forms of skepticism are seldom recognized as skepticism, the problem tends to remain hidden and unresolved. READ MORE
