Diurnal variation of the potassium layer in the upper atmosphere
Measurements of the diurnal cycle of potassium (K) atoms between 80 and 110 km have been made during October (for the years 2004-2011) using a Doppler lidar at Kühlungsborn, Germany (54.1°N, 11.7°E). A pronounced diurnal variation is observed in the K number density, which is explored by using a detailed description of the neutral and ionized chemistry of K in a three-dimensional chemistry clim...
متن کاملDiurnal Rhythm of Potassium
There has been a GREAT deal of BB (Bulletin Board) discussion about potassium. Such discussion has been devoted not only to its importance in general but also specifically to AF. There have been many anecdotal stories testifying to the latter. On the other hand, I’m sure there are many LAFers that are unable to detect any appreciable benefit from potassium supplementation. Perhaps there is an e...
متن کاملDiurnal variation in the nitrate content of parsley foliage
The diurnal fluctuation of nitrate concentration in the foliage of three parsley subspecies (plain-leafed, curly-leafed and turnip rooted parsley) cultivated in the spring and autumn of two consecutive years was examined. Nitrogen was applied at 30 (Control), 75, 150, 300 mg kg-1 in both years, but with the addition of 450 mg kg-1 in year 2. Harvest was carried out at 08:30, 12:30 and 17:30 on ...
متن کاملElectrochemical study of potassium isobutyl xanthate at a mercury electrode.
Polarographic studies of potassium isobutyl xanthate at a mercury electrode reveal that the product of an anodic reaction is strongly adsorbed at the mercury surface, as indicated by a prewave. The adsorbed film greatly affects the characteristics of the anodic wave of xanthate in an aqeous medium. The current of total wave is proportional to the concentration of xanthate from 0.32 to 1.6 mM.
