ESTIMATION OF WIND POWER DENSITY AT AN INTERNATIONAL AIRPORT

Journal of Energy Technology
This paper deals with the development of a statistical model for the assessment of wind power density, using the wind speed data acquired at an international airport. The data were adjusted for the height at which wind power could be harvested. Wind speed data were fitted with several statistical distributions in order to determine the one that best ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
