2. 1. Towards the Development of Photoswitchable β-Hairpin Mimetics

   Author : Máté Erdélyi; Adolf Gogoll; Anders Karlén; John A. Robinson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; β-hairpin; peptidomimetics; Sonogashira; NMR; photochemistry; microwave; peptide; palladium; Organisk kemi; Organic chemistry; Organisk kemi;

   Abstract : Peptide secondary structure mimetics are important tools in medicinal chemistry, as they provide analogues of endogeneous peptides with new physicochemical and pharmacological properties. The β-hairpin motif has been shown to be involved in numerous physiological processes, among others in regulation of eucariotic gene transcription. READ MORE

4. 2. Development of Transgenic Potatoes to Attain Novel Starch Qualities

   Author : Mariette Andersson; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; Biokemisk teknik; Biochemical technology; StGH; starch yield; RNAi; antisense; gene silencing; ahas; potato transformation; sbe2; sbe1; gbss; amylopectin; amylose; Starch; potato;

   Abstract : Starch is a plant-derived polysaccharide with many uses in different food and non-food applications. In this thesis, the production of two novel potato starch qualities, amylopectin and high-amylose, and the modifications and the characteristics of the produced plants and starches are described.

5. 3. Ageing of Asphalt Mixtures : Micro-scale and mixture morphology investigation

   Author : Prabir Kumar Das; Björn Birgisson; Nicole Kringos; Andreas Loizos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ageing; Aggregate packing; Atomic force microscopy; Asphalt mixture; Bitumen; Diffusion; Finite element analysis; Gradation; Micro-structure; Mixture morphology; Oxidative ageing; Surface ageing;

   Abstract : There are many variables that affect the viscoelastic properties of asphalt mixtures with time, among which age hardening may be considered one of the important ones. Age hardening of asphalt mixtures is an irreversible process, which contributes to a reduction of the durability of pavements and eventually increases the maintenance cost. READ MORE

6. 4. Development of Methods for Phase System Characterization in Liquid Chromatography

   Author : Jörgen Samuelsson; Torgny Fornstedt; Karin Caldwell; Attila Felinger; Uppsala universitet; []
   Keywords : Analytical chemistry; Liquid chromatography; Adsorption isotherms; Adsorption energy distribution; Tracer pulse method; Elution by characteristic points; Peak deformation; Validation; Hybrid column material; Alkaline separation; Injection-profiles; Analytisk kemi;

   Abstract : The aim of this thesis is first and foremost to improve the fundamental knowledge of nonlinear and preparative separation theory by focusing on some of the remaining “white spots” on the theoretical chromatographic map. Secondly, the acquired knowledge is used to develop, validate and execute new methods for phase characterization in liquid chromatography. READ MORE

7. 5. Towards an Effective Virtual Sheet Metal Assembly Development Process Securing Geometrical Quality and Equipment Utilization

   Author : Johan Segeborn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot motion planning; geometrical quality; equipment utilization; robust design; Sheet metal assembly; tolerance analysis;

   Abstract : Automobiles are an integral part of modern society and its way of life. In addition, automotive manufacturers are important institutions in society, summing the work of a vast array of sub suppliers, employing many. The margins are however moderate and competition is fierce. READ MORE
