Ultra high‐speed sorting [PDF]
Cytometry Part A, 2005 AbstractBackgroundCell sorting has a history dating back approximately 40 years. The main limitation has been that, although flow cytometry is a science, cell sorting has been an art during most of this time. Recent advances in assisting technologies have helped to decrease the amount of expertise necessary to perform sorting.MethodsDroplet‐based ...

Sand Penetration By High-Speed Projectiles [PDF]
, 2009 Tungsten projectiles were shot into sand at velocities between 600 and 2200 m/s. Penetration was maximum at about 775 m/s. Below that velocity, projectiles were apparently stabilized by a fin set.

Speed in a high-speed society [PDF]
International Journal of Injury Control and Safety Promotion, 2019 Speed control is the most important aspect of promoting road safety world-wide. The question is how are speeds developing? The European Transport Safety Council concludes: There is little progress on reducing speeds in Europe. Similar conclusions can be drawn from the US and Australia. Attitude surveys show that people's answers are not very consistent

High-speed sludge freezing [PDF]
Water Research, 2001 The investigation examined the feasibility of applying a "high-speed freezing technique, using liquid nitrogen freezing, to condition activated sludges and alum sludges. Experimental results indicate that the freezing speed is much faster than that adopted in most previous works on sludge freezing.
