1. 1. Föräldrars val av fristående skolor

   Författare :Jan Damgren; Utbildningsvetenskap; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pedagogik; Pedagogy and didactics; private good; public good; equality; segregation; Private schools; parents choice; didaktik;

   Sammanfattning : Abstract Although the number of children attending private schools in Sweden is less than 4% of those attending compulsory schools, the debate of these schools has been intense. Apart from details as fees and funding, the role of education’ in the Swedish welfare system has been subject of much debate. LÄS MER

3. 2. Nuclear Intonation in Swedish : Evidence from Experimental-Phonetic Studies and a Comparison with German

   Författare :Gilbert Ambrazaitis; Fonetik; []
   Nyckelord :HUMANIORA; HUMANITIES; parallel encoding; contrastive topic; new information; given information; focus; information structure; pragmatics; nucleus; sentence accent; prosody; word accent; F0; early peak; perception; reaction time;

   Sammanfattning : This thesis investigates Swedish intonation patterns and their interaction with word accent realisation in various pragmatic conditions, using German as a reference language. The point of departure is the wide-spread assumption that Swedish, as a language with a tonal word accent distinction, has a considerably smaller repertoire of nuclear intonation contours than German and other so-called intonation languages.

4. 3. Palladium-Catalysed Couplings in Organic Synthesis : Exploring Catalyst-Presenting Strategies and Medicinal Chemistry Applications

   Författare :Alejandro Trejos; Mats Larhed; Jianliang Xiao; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mizoroki-Heck arylation; Suzuki coupling; domino reaction; stereoselective; palladium; chelation control; vinyl ether; HIV-protease inhibitors; HIV-integrase inhibitors; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

   Sammanfattning : Palladium-catalysed coupling reactions have been embraced by synthetic chemists as one of the preferred means for smooth formation of new carbon-carbon bonds: a truly ubiquitous methodology of synthesizing complex molecules.This thesis describes the study of a series of palladium(0)-catalysed C2-arylations of a 1-cyclopentenyl ether, equipped with a chiral (S)-N-methyl-pyrrolidine auxiliary.

5. 4. Modeling, Control and Optimization of a Plate Reactor

   Författare :Staffan Haugwitz; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mid-ranging control; transition control; start-up; exothermic reaction; chemical reactor; modeling; process control; optimization; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : A new chemical reactor, the Alfa Laval Plate Reactor, is being developed by Alfa Laval, a Swedish world-leading heat exchanger company. The plate reactor combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors. LÄS MER

7. 5. Catalytic Reduction of NOx on Heavy-Duty Trucks

   Författare :Christian Künkel; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; real time; strategy; model; catalysis; exhaust gas; diesel; automotive; deNOx; NOx reduction; NOx storage; HC-SCR; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

   Sammanfattning : The objective of the work described in this thesis is to identify the principles and parts of an aftertreatment system for the catalytic NOx reduction for heavy-duty diesel vehicles, and to demonstrate such a system in full-scale. The reducing agent is diesel fuel. LÄS MER
