A new species of bacteria oxidizing ammonium with nitrite under anoxic conditions was isolated from the activated sludge of a semi-industrial bioreactor treating digested sludge of the Kuryanovo wastewater treatment plant (Moscow, Russia).

Contusion spinal injury of different severity was induced by the weight drop method in male rats by dropping standard weight from the heights of 6.5, 12.5, 25, and 50 mm on the spine after laminectomy at the Th9 level. The dynamics of recovery of voluntary movements was evaluated over 8 weeks after the operation by comparing the traditional semiquantitative(More)

The initial values of the horizontal and vertical visibility are assumed to be(More)
