1. 46. Design, Modelling and Control of Electrical Machines - With Applications to Iron-powder Machines and Acoustic Noise

   Författare :David Martinez; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BEM; induction machine; noise prediction; vector control; acoustic noise; HEV; series magnetization; leakage reduction; thermal model; FEM; MEC; claw-poles; SMC; slip-ring-less machine; sound intensity measurements; vibration; Electrical engineering; Elektroteknik;

   Sammanfattning : This thesis consists of two parts, the first dealing with the design of iron-powder synchronous machines, and the second with the analysis and prediction of the acoustic noise in electrical machines. In Part I, a 1.6 kW electrically magnetized claw-pole machine with magnetically conducting end-plates has been analyzed and a prototype tested. LÄS MER

3. 47. Märkesorientering - Utveckling av varumärken som strategiska resurser och skydd mot varumärkesdegeneration

   Författare :Mats Urde; Företagsekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; brand competence; resource-based strategy; trademark protection; genericness; trademark degeneration; brand identity; Brand strategy; brand orientation; management; Företagsledning; Management of enterprises;

   Sammanfattning : The aim of this study was to examine how an organisation’s approach to brands can, in the building up of a brand competence, prevent trademark degeneration and develop and protect brands as strategic resources. A line of argument is put forward for adopting a new corporate approach (mind-set) to brands. LÄS MER

4. 48. A study of the autogenous Hydrogen-DRI slag and its impact on the dephosphorization of fossil-free steel at different oxygen potentials

   Författare :Joar Huss; Pär Jönsson; Du Sichen; Niklas Kojola; Chris Pistiorius; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : The present study comprises aspects related to the phosphate capacity, the dephosphorization of fossil-free steel, and the utilization of potential by-products. The focus is mainly given to the functions and impact of the autogenous H-DRI slag in the dephosphorization process and the possibility for future slag valorization. LÄS MER

5. 49. Molecular and morphological studies on non-healing venous leg ulcers

   Författare :Katarina Lundqvist; Lund Dermatologi och venereologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; alpha1-microglobulin; heparin binding protein; venous leg ulcers; inflammation; alpha-defensin;

   Sammanfattning : Chronic skin ulcers are a major health problem and an increasing burden on health care providers. These ulcers have various underlying causes, such as venous or arterial insufficiency, diabetes, or vasculitis. Non-healing venous leg ulcers represent a condition characterized by excessive inflammation and presence of bacteria. LÄS MER

7. 50. Characterisation of Food Associated Bacteria by DNA based Methods, with Special Reference to Enterobacteriaceae

   Författare :Crister Olsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; 16S rRNA; TTGE; ribotyping; Rahnella; Klebsiella; HPI; Enterobacteriaceae; food; Livsmedelsteknik;

   Sammanfattning : The presence of genes in food, encoding some virulence factors, was studied by PCR, and species of Enterobacteriaceae, associated with food, were studied by the DNA-based methods of TTGE, ribotyping and sequencing. The flora of fresh and chill-stored pork were analysed by a culture-independent approach, using specific amplification of 16S rRNA genes followed by cloning and sequencing. LÄS MER
