Capillary interception of floating particles by surface-piercing vegetation.
Surface-piercing vegetation often captures particles that flow on the water surface, where surface tension forces contribute to capture. Yet the physics of capillary capture in flow has not been addressed. Here we model the capture of floating particles by surface-piercing collectors at moderately low Reynolds numbers (Re<10). We find a trade-off between the capillary force, which increases wit...
متن کاملFlows with suspended and floating particles
The evolution of the configuration of a set of particles dispersed in a flowing liquid is crucial in many applications such as sedimentation, slurry transport, rheology and structured arrays of micro and nano particles. Direct Simulation based on what is called Fictitious Domain Method coupled with Finite Element Method has been used to study particulate flows and sedimentation process. Here we...
متن کاملParticles in Plasma Processing Reactors: Modeling Nucleation, Transport, and Interparticle Effects to Reduce Wafer Contamination By
Plasma processing contamination continues to affect device yield in the microelectronics industry. Particles as small as tens of nanometers in radius may cause killer defects due to small feature sizes, which are decreasing to < 0.1 µm. In low pressure discharges (tens to hundreds of millitorr), particles charge negatively and are subject to charged particle forces (ion-drag and electrostatic),...
متن کاملSwimming Upstream, Floating Downstream: Trends in the U.S. and Danish Gender Wage Gaps
While the gender wage gap has reduced considerably in the U.S. since the late 1970s, in Denmark it has virtually stagnated over the same period. Using the U.S. CPS and the Danish Longitudinal Sample data, we compare the development in the gender wage gaps in these two countries between 1983-1995 in both time-series and microeconometric analyses. We present a new decomposition methodology that i...
متن کاملSwimming Upstream, Floating Downstream: Trends in the U.S. and Danish Gender Wage Gaps
We compare trends in the U.S. and Danish wage gaps between 1983 and 1995 using CPS and Danish Longitudinal Sample data. Using a new decomposition method, we show that returns to observable characteristics, selectivity and ranking effects outweigh women’s gains due to qualifications and account for the rising gap in Denmark, while both observed prices and the unexplained gap explain the decline ...
