2. 16. Fibre flow mechanisms

   Author : Roger Bergström; Ulf Björkman; Bo Norman; Mark Martinez; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre flow; floc; shear; compression; fibre network; stress chain; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : The flow behaviour, and primarily the floc-floc interaction, of pulp paper suspensions have been studied visually. Analogy models based on these observations have been developed as well as the identification of important parameters of floc break-up in low shear rate flow fields. READ MORE

4. 17. Quantum and Ballistic Nanodevices

   Author : Ivan Shorubalko; Fasta tillståndets fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductors; low-dimensional structures; nanostructures; ballistic rectifiers; three-terminal ballistic junctions; quantum wires; planar quantum dots; logic gates; harmonic generation; InP; GaInAs; nanoelectronics; Fysik; Physics; nonlinear transport; electron transport; quantum nanodevices; ballistic nanodevices; Fysicumarkivet A:2003:Shorubalko;

   Abstract : In this thesis, electron transport in quantum and ballistic devices was studied. The devices studied here were quantum wires, planar quantum dots, ballistic rectifiers, artificial functional materials, and three-terminal ballistic junctions. The possible application of such devices in the future nanoelectronics was also investigated. READ MORE

5. 18. The Relationship between Transmembrane Mucins, Ion Channels and PDZ Adaptor Proteins in the Small Intestine

   Author : Thaher Pelaseyed; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intestine; mucin; MUC3; MUC17; SEA; PDZK1; GOPC; CFTR; NHE3;

   Abstract : The human body is continuously exposed to challenges from the surrounding world. In analogy with the skin, mucus is a well-organized and highly regulated barrier composed of polymeric and O-glycosylated mucins that protects luminal organs such as the gastrointestinal tracts from the outer milieu.

6. 19. The moral status of nature : reasons to care for the natural world

   Author : Lars Samuelsson; Roger Fjellström; Johan Brännmark; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; Environmental ethics; ecocentrism; reasons; reason for action; normative reason; moral status; moral standing; moral considerability; final value; intrinsic value; biocentrism; nature-considerism; nature; nature as a whole; the natural world; complexity; indispensability; interests; Practical philosophy; Praktisk filosofi;

   Abstract : The subject-matter of this essay is the moral status of nature. This subject is dealt with in terms of normative reasons. The main question is if there are direct normative reasons to care for nature in addition to the numerous indirect normative reasons that there are for doing so. READ MORE

7. 20. Analogical reasoning in science education : - connections to semantics and scientific modelling in thermodynamics

   Author : Jesper Haglund; Helge Strömdahl; Konrad Schönborn; Roland Kjellander; Kevin Dunbar; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; science education; thermodynamics; analogical reasoning; semantics; scientific modelling; naturvetenskapsdidaktik; termodynamik; analogiskt tänkande; semantik; vetenskaplig modellering;

   Abstract : Analogiskt tänkande är en central kognitiv förmåga som vi använder i vardagslivet, såväl som i mer formella sammanhang, såsom i forskning och undervisning. Föreliggande avhandling behandlar hur analogier och analogiskt tänkande, uppmärksamhet på semantik och förståelse för vetenskaplig modellering kan användas för att hantera utmaningar i naturvetenskapsundervisningen, särskilt inom området termodynamik.
