   Sammanfattning : Solid oxide fuel cells (SOFCs), working at high temperatures with an incomplete fuel oxidation process, have become an interesting candidate for combination with conventional power generation technology, such as gas turbines, in order to develop power plants that are both functional and efficient. An absolute condition for successful analysis and optimisation of such plants is the existence of reliable simulation tools. LÄS MER

4. 23. Thermodynamic Modelling and Performance of Combined Solid Oxide Fuel Cell and Gas Turbine Systems

   Författare :Jens Pålsson; Kraftverksteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; Gases; fluid dynamics; plasmas; plasma; hydraulik; Maskinteknik; vibration and acoustic engineering; hydraulics; vacuum technology; Modelling; Mechanical engineering; Solid oxide fuel cell; Hybrid system; Gaser; fluiddynamik;

   Sammanfattning : Solid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. LÄS MER

5. 24. Ion escape from Mars

   Författare :Qi Zhang; Mats Holmström; Xiao-Dong Wang; Shahab Fatemi; Hans Nilsson; David Andrews; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : When the solar wind reaches the Mars obstacle, mass loading by planetary ions slows down the solar wind and raises the bow shock. The Martian atmosphere is undergoing the a scavenging by the solar wind without the protection of a global magnetic field. Atmospheric escape is an important process for the evolution of the Martian climate. LÄS MER

7. 25. Genetic Characterisation of Human ABO Blood Group Variants with a Focus on Subgroups and Hybrid Alleles

   Författare :Bahram Hosseini Maaf; Avdelningen för hematologi och transfusionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosyltransferase; SNP; computer modelling; ABO genotyping; Immunology; serology; hybrid; Blood group ABO; transplantation; subgroup; Immunologi; serologi; rare O allele;

   Sammanfattning : ABO is the most important blood group system in transfusion medicine and transplantation immunology. The ABO blood groups differ by the presence or absence of antigens on RBCs and antibodies in plasma. Accurate determination of ABO status is critical. Genomic typing can increase the precision of blood group determination in complicated cases, e. LÄS MER
