   Sammanfattning : The dissertation concerns F. A. Hayek’s (1899–1992) critique of legislation. The purpose of the investigation is to clarify and assess that critique. LÄS MER

3. 7. A numerical study of two-fluid models for dispersed two-phase flow

   Författare :Reynir Levi Gudmundsson; Björn Sjögreen; Anders Petersson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; two-phase flow; two-fluid mode; well-posedness; numerical experiments; Numerisk analys; Numerical analysis; Numerisk analys;

   Sammanfattning : In this thesis the two-fluid (Eulerian/Eulerian) formulation for dispersed two-phase flow is considered. Closure laws are needed for this type of models. We investigate both empirically based relations, which we refer to as a nongranular model, and relations obtained from kinetic theory of dense gases, which we refer to as a granular model. LÄS MER

4. 8. The influence of inertia on the rotational dynamics of spheroidal particles suspended in shear flow

   Författare :Tomas Rosén; Fredrik Lundell; Minh Do-Quang; Johan Revstedt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; dispersed particle flows; inertia; non-spherical particles; non-linear dynamics; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Dispersed particle flows occur in many industrial, biological and geophysical applications. The knowledge of how these flow behave can for example lead to improved material processes, better predictions of vascular diseases or more accurate climate models. LÄS MER

5. 9. Characterization of selective solar absorbers : Experimental and theoretical modeling

   Författare :Tuquabo Tesfamichael; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Sammanfattning : This thesis deals with the preparation, optical characterization and analyses of experimental work and theoretical modeling on selective solar absorbers used in solar thermal collectors. The overall goal has been to obtain efficient absorbers by optimizing the optical properties, and to improve their durability using cost-effective techniques. LÄS MER

7. 10. Characterisation of Aqueous Solutions, Liquid Crystals and Solid State of Non-ionic Polymers in Association with Amphiphiles and Drugs

   Författare :Annika Ridell; Martin Malmsten; Sven Engström; David Attwood; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; polymer; surfactant; phase diagram; x-ray diffraction; fluorescence spectroscopy; calorimetry; PEG; cellulose ether; viscometry; cubic phase; liquid crystals; drugs; solid dispersion; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Fysikalisk och oorganisk farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry;

   Sammanfattning : Cellulose ethers and polyethylene glycols are used in drug formulations as water swelling or water soluble matrices. Polar lipids, for example monoglycerides, and surfactants can be used to solubilise hydrophobic or amphiphilic drugs and to formulate potential drug delivery vehicles such as emulsions, liposomes and cubic phases.
