1. 16. Experiments on biofilm formation and growth in laminar flows

   Författare :Cornelius Wittig; Shervin Bagheri; Thomas Crouzier; Wouter van der Wijngaart; Eleonora Secchi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilm; streamers; wall shear stress; OCT; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : The interaction between fluid dynamics and biofilm growth plays a key role in both medical and industrial applications. Biofilms, or bacteria that are embedded in a protective matrix of extracellular polymeric substances, settle on interfaces such as on implanted devices or ship hulls. LÄS MER

3. 17. What's Next? : Organising Complex Product Development with Lean

   Författare :Caroline Ingvarsson; Mats Engwall; Lars Uppvall; Anette Hallin; Pascal Le Masson; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Lean Knowing-in-practice Work organisation; Product Development; Industriell ekonomi och organisation; Industrial Economics and Management;

   Sammanfattning : An everyday question asked during complex product development work is, ‘What to do next’? Not just because the development in itself is advanced and integrated, but also because it is planned and performed in large organisations, in difficult projects, and across organisational lines. There have been different approaches to try and reduce the difficulty of having to organise complex product development, primarily through using different kinds of management models. LÄS MER

4. 18. Flow characterisation of drainage cannulae and centrifugal pumps used in extracorporeal membrane oxygenation: an experimental investigation

   Författare :Federico Rorro; Lisa Prahl Wittberg; Lars Mikael Broman; Louis P. Parker; Fredrik Lundell; Ulrich Steinseifer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

   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

5. 19. Measurement and Analysis of Intracardiac Blood Flow and Vortex Ring Formation

   Författare :Johannes Töger; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood flow; dynamical systems; magnetic resonance imaging; heart failure; vortex ring formation;

   Sammanfattning : Increased understanding of the pumping mechanics of the heart are of great importance to develop diagnostics, treatment and prognostics for cardiovascular diseases. Blood flow in the heart is connected to its anatomy and function, and may therefore be a sensitive marker of cardiac health and disease. LÄS MER

7. 20. Dynamic Modelling and Simulation of Liquid Food Process Lines

   Författare :Tomas Skoglund; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process lines; Dynamic model; Microbial deactivation; Data- och systemvetenskap; computer technology; Systems engineering; Fuzzy traceability; Traceability; Thermal engineering; termodynamik; Termisk teknik; applied thermodynamics; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; Heat exchanger; Dispersion; Fluid property transition; Liquid food; Dynamic simulation; Livsmedelsteknik;

   Sammanfattning : In the present work a dynamic model library of components for process lines was developed. The analysis addressed characteristic aspects of liquid food process lines, and new models were developed for fluid transitions, dispersion, mixing zones and first-order chemical reactions in pipes and heat exchangers.
