1. 26. Novel Solid Phase Extraction and Mass Spectrometry Approaches to Multicomponent Analyses in Complex Matrices

   Författare :Nahid Amini; Gunnar Thorsén; Tuulia Hyötyläinen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sample preparation; SPE; RAM; GCB µ-trap; GCB disk; High temperature LC; LC MS; ESI; APCI; Matrix effects; LIT-MS; SALDI; Sample screening; Oxidized GCB; Silicon nitride; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : Analysis of compounds present in complex matrices is always a challenge, which can be partly overcome by applying various sample preparation techniques prior to detection. Ideally, the extraction techniques should be as selective as possible, to minimize the concentration of interfering substances. LÄS MER

3. 27. Circulating biomarkers in patients with abdominal aortic aneurysm

   Författare :Despina Flondell-Sité; Vaskulära sjukdomar - kliniska studier; []

   Sammanfattning : Abdominal aortic aneurysm (AAA) develops in 3-6% of the population over 65 years and affects mainly men. AAA has a complex etiology involving inflammation, proteolysis, fibrinolysis and coagulation. LÄS MER

4. 28. Interactions between extracellular matrix proteins and the complement system - In the perspective of cartilage degradation in inflammatory joint diseases

   Författare :Camilla Melin Fürst; Malmö Proteinkemi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Complement system; rheumatoid arthritis; osteoarthritis; extracellular matrix; cartilage degradation; mass spectrometry;

   Sammanfattning : Abstract: The joint diseases osteoarthritis and rheumatoid arthritis are characterized by destructive inflammatory processes that result in pathological changes of the joint tissues, including proteolytic degradation of cartilage and release of extracellular matrix proteins or fragments to the synovial fluid. The complement system, which is a part of the innate immune system, plays a central role in promoting the joint inflammation in these diseases. LÄS MER

5. 29. Vehicle Conceptualisation, Compactness, and Subsystem Interaction : A network approach to design and analyse the complex interdependencies in vehicles

   Författare :Sai Kausik Abburu; Carlos Casanueva; Ciarán J. O'Reilly; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subsystem interaction; Interaction effects; Design Structure Matrix; Network theory; Cross-scalar design tool; Induction motor; Inverter.; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : The conventional approach to vehicle design is restrictive, limited, andbiased. This often leads to sub-optimal utilisation of vehicle capabilities and allocated resources and ultimately entails the repercussions of designing andlater on an using an inefficient vehicle. LÄS MER

7. 30. Origin-destination matrix estimation from traffic counts

   Författare :Anders Peterson; Henrik Edwards; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : For most kind of analyses in the field of traffic modeling, there is a need for origin-destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. The process of obtaining OD-matrices is long, complicated and expensive. LÄS MER
