1. 16. High power bipolar junction transistors in silicon carbide

   Författare :Hyung-Seok Lee; Carl-Mikael Zetterling; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide SiC ; power device; biplar junction transistor; TiW; ohmic contact; current gain; Electronics; Elektronik;

   Sammanfattning : As a power device material, SiC has gained remarkable attention to its high thermal conductivity and high breakdown electric field. SiC bipolar junction transistors (BJTs) are interesting for applications as power switch for 600 V-1200 V applications. LÄS MER

3. 17. An analytical framework for studying transcriptional regulation

   Författare :Christoph Sebastian Börlin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transcription factor; ChIP-exo; S. cerevisiae; transcriptional regulation;

   Sammanfattning : The state and behavior of any living cell is controlled by a complex interplay of different regulatory processes, with the regulation of transcription playing a major role. When a cell adapts to a new environment it often does that by modulating gene transcript levels, mainly through changes in transcription factor binding events. LÄS MER

4. 18. Smoking and Breast Cancer

   Författare :Jonas Manjer; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; triglycerides; Nottingham Prognostic Index; hormone receptor; socioeconomic; risk factor; smoking cessation; breast cancer; smoking; survival; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

   Sammanfattning : Ex-smokers are exposed to a higher breast cancer risk than are never smokers. This conclusion is based on a follow-up of the 10 902 women in the Malmö Preventive Project. The 31% higher incidence in ex-smokers remained statistically significant when other risk factors were taken into account in the analysis. LÄS MER

5. 19. Pancreatic carcinoma in Malmö, Sweden: Clinical, epidemiological and biochemical aspects

   Författare :Mats Hedberg; Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kirurgi; Pancreatic carcinoma; survival rate; epidemiology; incidence rate; risk factors; smoking; weight gain; gastric resection; cholecystokinin; Surgery; pancreatic enzymes; traumatology; traumatologi; ortopedi; orthopaedics;

   Sammanfattning : The objective of this thesis has been to assess whether there are indications suggesting that new methods for diagnosis and treatment of pancreatic carcinoma (PCa) has been followed by an improved prognosis, and to assess the possible role of smoking and gastric resection in the causation of the disease. Of the 1,200 new cases PCa diagnosed in Sweden yearly, the majority are older than 70 years, the case fatality rate being close to 100%. LÄS MER

7. 20. Rule-based Models of Transcriptional Regulation and Complex Diseases : Applications and Development

   Författare :Susanne Bornelöv; Jan Komorowski; Claes Wadelius; Joanna Polanska; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Histone modification; Transcription factor; Transcriptional regulation; Next-generation sequencing; Feature selection; Machine learning; Rule-based classification; Asthma; Allergy; Bioinformatik; Bioinformatics;

   Sammanfattning : As we gain increased understanding of genetic disorders and gene regulation more focus has turned towards complex interactions. Combinations of genes or gene and environmental factors have been suggested to explain the missing heritability behind complex diseases. LÄS MER
