1. 16. Spherical Crystallization of Benzoic Acid

   Författare :Jyothi Thati; Åke Rasmuson; Luis Moreno; Eva Blomberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Spherical agglomeration; Benzoic acid; Solubility phase diagram; Physico mechanical properties; Chemical engineering; Kemiteknik;

   Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water. LÄS MER

   Författare :Carl Oliver Blomqvist; Staffan Fridell; Hanna Lehti-Eklund; Terhi Ainiala; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Old Swedish; Finnish; code-switching; historical sociolinguistics; toponyms; anthroponyms; charters; Middle Ages; Nordiska språk; Scandinavian Languages;

   Sammanfattning : This thesis examines fragmentary Finnish in Late Old Swedish charters (c. 1350–1526) issued in the Finnish part of the Swedish realm, the diocese of Åbo. LÄS MER

4. 18. Structure Evolution during Phase Separation and Gelation of Biopolymer Mixtures

   Författare :Niklas Lorén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; gelatin maltodextrin; biopolymer mixtures; structure evolution; phase separation; stereology; confocal laser scanning microscopy; image analysis; spinodal decomposition; transmission electron microscopy; gelation;

   Sammanfattning : This thesis focuses on the kinetics of phase separation and gelation in aqueous mixtures of gelatin and maltodextrin. The structure evolution of these mixtures at different length scales was recorded by confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM). The microstructure was quantified by image analysis. LÄS MER

5. 19. New approaches to preparation of macroporous monoliths for use in liquid chromatography

   Författare :Anh Mai Nguyen; Knut Irgum; Tatiana B. Tennikova; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monolith; polycondensation; dissolution-precipitation; epoxy-amine; poly-amide; nylon; emulsion polymerization; characterization; protein separation; liquid chromatography; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

   Sammanfattning : High performance liquid chromatography (HPLC) is one of the major techniques in separat-ion sciences. Faster separation and higher efficiency are required to meet ever-growing demands. Despite numerous studies and achievements on improving mass transfer in particulate packings discontinuity seems to be the cornerstone drawback in their development. LÄS MER

7. 20. Mechanics-based Design Framework for Flexible Pavements

   Författare :Yared H. Dinegdae; Björn Birgisson; David Newcomb; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanics-based; asphalt; fatigue; reliability; traffic; variability; Mekanik-baserade; utmattningssprickor; pålitlighet; lastbilstrafiken; variabilitet; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Load induced top-down fatigue cracking has been recognized recently as a major distress phenomenon in asphalt pavements. This paper presents a mechanics-based design framework in load and resistance factor design (LRFD) format for the top-down fatigue cracking performance evaluation of flexible pavements. LÄS MER
