The studied tailing dump is located on a hill in the urban village limits (Komsomolsk, Kemerovo region) and contained cyanidation wastes. There are the comprehensive school and the central street of the city below a hill, and the kindergarten on the opposite hill. Due to the easy availability of atmospheric oxidizing factors, the material of the bulk dumps changes very quickly, and, of course, seeps into the hill. Two types of streams interact with the material of the Berikul bulk dumps: infiltration water that se...

The reason for the creation of playgrounds was the effort to get playing children off the city streets where they could get injured due to increasing car traffic. More than 160 years have passed since, and the playgrounds have gradually been transformed according to the needs of the time. Denser traffic, and generally a sense of greater discomfort among strangers, have increased demands on finding ways how to satisfy all the needs of the children with their escort. With the development of transportation, the feeli...

The generally accepted representation of global geoid/quasi-geoid models in a series of spherical harmonics expansion turns out to be inappropriate for geoid modelling in relatively small local areas. To obtain a resolution of a few kilometers requires the development of spherical functions to critically high degrees of expansion, which leads to instability of the solution for several reasons, which are discussed in the article. For that reason, to determine precise local model of the geoid, it is necessary to use...
