[The sanitary microbiological and biochemical characteristics of the soils under the conditions of urbanization]. / Sanitarno-mikrobiologicheskaia i biokhimicheskaia kharakteristika pochv v usloviiakh urbanizatsii.

The study of soils under technogenesis and urbanization has shown that their biogenic properties are preserved. Sanitary assessment of urban soils has demonstrated their moderate and severe pollution, bean plants being found to have self-purifying capacities in the soils.

[Structural characteristics of the axons of nerve cells of the cat motor cortex]. / Strukturnaia kharakteristiki aksonov nervnykh kletok dvigatel'noi kory mozga koshki

The axons of both pyramid and stellate neurons have a great number of ramifying collaterals which are considered in a comparative aspect. The both types of nerve cells are characterized by almost similar systems of the branching of axons, types of collaterals and end structures. The neurons are distinguished due to progressive development of one features of the axon structure and to a certain reduction of the others. In extreme forms the stellate cells have a well developed pericellular network, not coming outside the limits of the branching of their dendrites, while the pyramid cells are characterized by the mighty development of the main trunk and the absence of recurrent collaterals. Between these forms there are transitional forms.
