Direct measurements of the capture efficiency of planktonic cells by seven solitary ascidians were made in situ and in the laboratory and compared with the capture efficiency of polystyrene ...

A hydrodynamic model was developed to examine particle capture by lophophores of encrusting bryozoans. Particle capture rate is predicted to increase with increasing speed of the feeding current.

Theoretical physicist David Kaplan discusses his new documentary “Particle Fever,” which followed scientists around the world for seven years as they hunted for the Higgs boson. Video by Justin ...

Particle size analysis has a wide variety of applications which encompass virtually all industries. There are multiple automated techniques that exist for measuring particle size distribution. Nearly ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The Christian Science Church, and we’ve always been transparent about that. The Church publishes the Monitor ...

Today’s standards define airborne particle monitoring in units of particles per cubic meter (particles/m 3). These standards tend to require sampling an entire cubic meter (1 m 3) to establish an ...
