There are various relations between macrofauna of phytal and pelagial in standing waters. A method is presented, which makes possible integrated quantitative investigations of the macrofauna of both coenosis. For the purpose of this a cubic box is...

The steady-state kinetics of 1,3-bisphosphoglycerate formation through the action of phosphoglycerate kinase on 3-phosphoglycerate and ATP have been examined. The results show that initial velocities determined by the standard method of coupling b...

Treatment of LLC-PK1-a...
