1. 26. Strength in Numbers – Droplet Microfluidics for Multicellular Ensemble Applications

   Författare :Martin Trossbach; Aman Russom; Håkan Jönsson; Nicole Pamme; KTH; []
   Nyckelord :Droplet Microfluidics; High-Throughput Screening; Microtissues; Microreactors; Cell Factories; Cell Culture; Biomaterials; Spheroids; Biotechnology; Bioteknologi;

   Sammanfattning : The work presented in this doctoral thesis explores multicellular, biological, and biotechnological applications for microfluidic droplets, making use of a number of unique features of these miniaturized, highly scalable reaction vessels.Droplet microfluidics specializes in pico- to nanoliter sized aqueous droplets in an immiscible oil phase, borrowing techniques from the field of microfluidics, namely fluid actuation, detection systems and electronic peripherals.

3. 27. The influence of particle shape of coating pigments on their packing ability and on the flow properties of coating colours

   Författare :Sven Lohmander; KTH; []
   Nyckelord :aspect ratio; capillary viscometry; coating colour; filtration. Particle packing;

   Sammanfattning : The influence of particle shape of coating pigments on theirpacking ability and on the flow properties of coating colourshas been investigated. The particle shapes considered werespherical, flaky and acicular (needle-shaped). LÄS MER

4. 28. A measurement approach to determination of coating thickness with eddy currents and to a capacitive person detector for robot safety

   Författare :Lennart Båvall; Keijo Nikoskinen; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : The research presented in this thesis is about coating thickness measurements using eddy currents, and a capacitive detector for detecting humans, for safety in industry.A method for determination of coating thickness of a copper-plated steel wire by measurement of the internal wire impedance, when this is forced by a constant, sinusoidal current, is presented.

5. 29. Microstructural changes in high strength steels exposed to large deformation and high strain rates

   Författare :Kristina Ryttberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; deformation mechanisms; high-velocity forming; high-velocity parting-off; adiabatic shear band; cold ring rolling; TEM; steel;

   Sammanfattning : Increasing steel prices and environmental aspects have put forward the demand to reduce material consumption and energy usage in manufacturing industry and near-net-shape manufacturing techniques have thus become increasingly important. High-velocity parting-off,high-velocity forming and cold ring rolling are three such manufacturing methods that exhibit great potentials in terms of material waste reduction. LÄS MER

7. 30. Modelling of steatosis and insulin resistance development in human hepatic 3d spheroids : mechanisms and genetic aspects

   Författare :Mikael Kozyra; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Hepatic steatosis and insulin resistance are common disease manifestations seen in metabolic syndrome, non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes (T2D) patients. Aberrant hepatic lipid accumulation leads to both morphological changes and metabolic alterations in liver function and may cause serious end-stage liver disease. LÄS MER
