1. Flow characterisation of drainage cannulae and centrifugal pumps used in extracorporeal membrane oxygenation: an experimental investigation
Sammanfattning : Extracorporeal membrane oxygenation (ECMO) is a life-saving treatment for acute respiratory and/or circulatory failure. Typically driven by a centrifugal pump, blood is drained from the patient via one drainage cannula, oxygenated by a membrane lung and returned to the patient via the return cannula. LÄS MER
2. System studies of MCFC power plants
Sammanfattning : Die Brennstoffzelle ist ein elektrochemischer Reaktor und wandelt chemisch gebundene Energie direkt in elektrische Energie um. In der stationären Energieerzeugung ist der Brennstoffzellenstapel selbst nur ein kleiner Bestandteil des vollständigen Systems. LÄS MER
3. Power-Based Two-Ports with Application to HVAC Systems
Sammanfattning : The understanding of acoustic wave propagation in ducts or pipes is essential for all applications involving fluid machines, e.g., fans, pumps, and compressors. Over the years different methods have been developed to simulate wave propagation in duct networks. LÄS MER
4. Performance evaluations of high-temperature cooling systems in Mediterranean climate
Sammanfattning : Cooling demand in Europe is predicted to grow 25-50% between 2020-2050. Meanwhile, the EU aims to lower the greenhouse gas emissions from its building stock by 60%. Therefore, it is essential to find solutions that can meet the growing cooling demand with less energy and integrate renewable energy sources. LÄS MER
5. Antiporter-like protein subunits of respiratory chain complex I
Sammanfattning : Complex I is the mitochondrial enzyme complex that oxidizes NADH produced in the citric acid cycle and reduces quinone in the membrane, coupled to proton pumping out of the mitochondrial matrix, creating a membrane potential. This process generates about 40% of the energy used by living organisms. LÄS MER
