PAMs are organic substances that dissolve, disperse, or swell in water [8-12] and thus find widespread use in industrial processes such as in drinking and industrial wastewater treatment [13], oil sand tailings treatment [14], improvement of soil stability [15], and enhanced oil recovery [16].
Thus, understanding the interaction between variously charged
PAMs and these two common clay minerals, i.e.
Comparison of the effects of the 2
PAMs (combined with PG) on the final IR and cumulative runoff indicated that, in the loamy sand, loam, and clay-E, use of PAM(H) led to larger final IR and smaller cumulative runoff values than an application of PAM(M) (Figs 2 and 3).
There has been an increasing interest in using polyacrylamide (
PAM) for erosion control as well, largely because of its highly successful introduction to irrigated agriculture in the last decade.
A good example of voice quality testing systems can be seen in a typical GL Communications system comprised of PC-based software, which is capable of executing
PAMS, PSQM/PSM+, and the PESQ algorithms which are capable of comparing a test signal and a degraded version that has been passed through a distorting system.
PAMs are a type of polymer that have been demonstrated to rapidly and irreversibly absorb on solid surfaces.
The
Pams reckon they were destined to meet as their father and mother lived in the same street and attended the same school.
Sojka credits Isaac Shainberg with first realizing that low concentrations of
PAMs might halt erosion.
The application of
PAMs reduced sediment concentration in rainfall runoff by 22-54%.
Because of stricter water-quality regulations, polyacrylamide (
PAM) conservation technology in irrigated agriculture has gained rapid acceptance in recent years.
