1. 6. Thermodynamic study of the FeO-MgO-Al2O3-SiO2 system : Data assessment and phase diagram calculation

   Författare :Olga Fabrichnaya; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

   Sammanfattning : This dissertation consists of assessed thermodynamic properties for phases in the geologically and industrially important system Fe-Mg-Al-Si-O and calculated phase diagrams. Mathematical processing of different kinds of experimental data (phase equilibrium data, calorimetric, volumetric, thermophysical,electrochemical, activity data) is used to derive internally consistent thermodynamic database.

3. 7. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

   Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

   Sammanfattning : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. LÄS MER

4. 8. Development of Dual-broadband Rotational CARS for Combustion Diagnostics

   Författare :Joakim Bood; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; N2; O2; C2H2; Dimethyl Ether DME ; High pressure; Stray light filtering; multi-point CARS; CARS; Temperature; Engine knock; Physics; Fysik; Fysicumarkivet A:2000:Bood;

   Sammanfattning : The present thesis concerns development and application of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (DB-RCARS) for temperature and species concentration measurements in combustion processes. Both fundamental development of the technique, including experimental as well as modelling results, and measurements in practical combustion devices were conducted. LÄS MER

5. 9. Simulation of the Melting and Cooling of Palladium Clusters

   Författare :Jan Westergren; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; melting; energy transfer; density of states; metal clusters; cooling; collision; phase barrier; sticking;

   Sammanfattning : The thermal behaviour of palladium clusters has been investigated using Monte Carlo simulation in various ensembles. Furthermore the energy transfer between palladium clusters and rare gas atoms has been calculated in simulated collisions aiming for a calculation of the cooling of clusters in a rare gas atmosphere.

7. 10. Theory of Crystal Fields and Magnetism of f-electron Systems

   Författare :Massimiliano Colarieti Tosti; Olle Eriksson; Walter Temmerman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Crystal Field; Magnetism; Electronic Structure; Teoretisk fysik; Physics; Fysik;

   Sammanfattning : A parameter free approach for the calculation of the crystal field splitting of the lowest Russel-Saunders J-multiplet in f-electron systems has been developed and applied to selected compounds. The developed theory is applicable to general symmetries and is based on symmetry constrained density functional theory calculations in the local density or in the generalised gradient approximation.
