2. 21. Manufacturihng of heavy rings and large copper canisters by plastic deformation

   Author : Hamzah Ssemakula; KTH; []
   Keywords : pores; grain size; low forginnig load; effective strain;

   Abstract : Plastic deformation processes transform material fromas-received state to products meeting certain requirements inproperties, microstructure and shape. To achieve thistransformation, the relationship between material response andprocess conditions should be understood. READ MORE

4. 22. Efficient Partitioning of Dynamic Structured Grid Hierarchies

   Author : Johan Steensland; Michael Thuné; Jarmo Rantakokko; Charles Norton; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; scientific computing; partitioning; structured grids; adaptive mesh refinement; dynamic load balancing; Beräkningsvetenskap; Scientific Computing;

   Abstract : This thesis aims at decreasing execution time for large-scale structured adaptive mesh refinement (SAMR) applications executing on general parallel computers. The key contributions are (1) A conceptual dynamically adaptive meta-partitioner able to select and configure an appropriate partitioning technique, based on application and computer state, and (2) A characterization of new and existing domain-based partitioners, enabling a mapping from application and computer state onto appropriate partitioners, and (3) Sketched scalable solutions, expressed in terms of natural regions and expert algorithms, for the problem to efficiently partition large-scale SAMR applications with deep grid hierarchies executing on general parallel computers, and (4) A software partitioning tool Nature+Fable, implementing the greater parts of these sketched scalable solutions and engineered as part of the meta-partitioner.

5. 23. Effects of fusion tags on protein partitioning In aqueous two-phase systems and use in primary protein recovery

   Author : Cynthia Hassinen; KTH; []
   Keywords : E. coli; Aqueous two-phase systems; Fusion proteins; Hydrophobic interaction chromatography; Expanded bed adsorption; Beta-galactosidase; Klenow polymerase; Z-domain; Peptide tags;

   Abstract : The two techniques aqueoustwo-phase partitioning and expanded bed adsorption that bothare suitable for primary protein recovery were studied. Most ofthe work was focused on partition in aqueous two-phase systemsand in particular on the possibility to effect the partitionbehaviour by fusion of short peptide tags or protein domains tothe target protein.

6. 24. Development of AIDS associated and endemic Kaposi sarcoma : HHV-8/KSHV viral load in cutaneous and oral tumor cells

   Author : Fatemeh Pak; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Oral Kaposi s sarcoma . HHV-8 . immunohistochemistry; PCR ; lymphatic ascular endothelium;

   Abstract : Kaposi's sarcoma (KS) is a highly and abnormally vascularized tumor-like lesion which usually presents as a cutaneous lesion and eventually progresses to systemic disease usually in the gastrointestinal (G1) tract, lungs, oral cavity and lymph nodes. Whether KS represents a predominantly monoclonal neoplastic cell proliferation or a hyperplastic, reactive polyclonal process is still controversial. READ MORE

7. 25. Reliability-based Design Procedure for Flexible Pavements

   Author : Yared Hailegiorgis Dinegdae; Björn Birgisson; Nicole Kringos; Nils Rydén; William Buttlar; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Top-Down fatigue cracking; asphalt mixture morphology; fracture mechanics; response surface; reliability analysis; load resistance factor design; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : Load induced top-down fatigue cracking has been recognized recently as a major distress phenomenon in asphalt pavements. This failure mode has been observed in many parts of the world, and in some regions, it was found to be more prevalent and a primary cause of pavements failure. READ MORE
