He teaches at the University of the Arts in Zurich. English Masque Dances. British Library contains the largest collection of dances from the early-seventeenth-century courtly masques to have survived, and it is thought that it was compiled by Sir Nicholas Le Strange of Hunstanton about 1624.
The USEPA recommends a limit of 0.02 ppm as NH3 in freshwater or marine environments. Total ammonia levels, at this limit, can range from 160 ppm at pH 6 and temperature of 5 degrees C to 0.06 ppm at pH 9 and temperature of 25 degrees C.he USEPA recommends a limit of 0.02 ppm as NH3 in freshwater or marine environments.

There is a slight decrease in the un-ionized ammonia fraction of total ammonia as the ionic strength of the solution increases. A method to estimate un-ionized ammonia in saline waters is provided in Appendix III.he right-hand side of (5) is equal to f, the fraction (mole fraction) of un-ionized ammonia. (See page 7 of Reference 1.) Also, f x 100 is the un-ionized ammonia percent (the numerical values in Table 2 of Reference 1).
