The Dow study also used a Randcastle single-screw extruder with similar mixing geometry to determine that the "SFEM's primary deformation mode is elongational (as opposed to shear-dominated)," and added that "a single-screw extruder equipped with SFEM mixing elements achieved even finer dispersion, usually achievable only with twin-screw extruders.
But Luker notes that the batch and screw SFEM mixers have essentially the same geometry.
Nowadays the described method based on SFEM
is being developed.
Once the platoon linked with the 41st FAB south of An Najaf, the SFEM began a baseline for a third-order network (a third-order point provides an 8-digit grid coordinate).
The SFEM had to be flexible to break camp and push out with the tactical road march to the next location and then immediately start tracking satellites to permit the artillery surveyors to extend control to allow greater accuracy.
Luo and Tanner  developed SFEM
for the swell problem without recirculation flows.
This paper also presents mixing tests performed with the original SSE using a newly designed SFEM
At Antec 2008, a novel screw was introduced called the Elongator which has spiral flutes and elongational flow, hereafter the SFEM
