   Nyckelord :shear oscillation; actuator; Quartz crystal microbalance; amplitude; streptavidin; lipid vesicles; biosensor; colloidal particles; size distribution; QCM-D; protein binding; DNA hybridization; dual harmonic; lipid bilayer formation;

   Sammanfattning : The QCM-D (quartz crystal microbalance with dissipation monitoring) technique is an increasingly popular tool in studies of molecular interactions at interfaces, e.g. binding/unbinding reactions at surfaces, studies of thin film properties, and conformational changes. LÄS MER

3. 7. Climate Change Effects on Rainfall and Management of Urban Flooding

   Författare :Arun Rana; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Climate Change; Extreme Events; Intensive Rainfall; Urban Drainage; Intensity-Duration-Frequency; Statistical analysis; Flood Management;

   Sammanfattning : Flooding in urban basins is intensifying due to increasing urbanization and climate change and variability. This thesis presents how the effects of climate change and high-intensive rainfall on the urban drainage system and management of flooding in urban areas of were studied in Mumbai, India and Southern Sweden, including Skåne and Gothenburg.

5. 9. Dynamics and Applications of Long Josephson Junctions

   Författare :Yongming Zhang; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The first object of this work is to theoretically study the effects of tunnel junction parameters on flux-flow Josephson oscillators (FFOs) by numerical simulation and to experimentally study the rf properties of FFOs by integrating them together with an SIS (superconductor-insulator-superconductor) mixer/detector on a chip. By using a CAD modeled integrated sub-mm wave receiver, the composite linewidth of two FFOs was measured to be less than 2. LÄS MER

7. 10. Simulations of compressible flows associatedwith internal combustion engines

   Författare :Olle Bodin; Laszlo Fuchs; Mihai Mihaescu; Michael Leschziner; KTH; []
