Prediction technique of toxic activity of small dozes of trace elements anthropogenic originally on genetic conditionality of biological effect

Physical and mathematical principles of modeling algorithms of biophysical quantum mechanisms and evolution laws of self-organizing of the molecular-biological apparatus of ecological information preservation in genetic memory due to coding chemico-physical properties of each element in DNA structure are stated. The prediction technique of biological activity pattern of trace elements anthropogenic originally on genetic conditionality of selective penetration processes of trace elements through a membrane into a living cell is offered; and also the realization technique of its toxic or other functions at an intracellular biochemical metabolism level is suggested.

Organization of work on fire safety on a railway transport

The mobility level of fire units of the militarized guard and the state fire-prevention service is analyzed. Distribution laws for all parameters of mobility are determined under the probability theory and random processes. The new circuit of fire warning on a railway transport and the algorithm of a choice of forces and means of fire units are offered.

Application of fuzzy logic at modeling of railway crossing functioning

The simulation model allowing to investigate the functioning of any crossing located on the railway under various conditions and amount of movement of trains and motor transport is offered. The distinctive feature of this model is taking into account of the majority of crossing own distinctive features and random change possibility of various factors. Application of fuzzy logic method at modeling provides the maximal approach of simulated process to real motor transport control process if there is a human factor.

Role of transport in formation of geosocioeconological field of urban settlements

Investigations on transport problems of urban settlements are generalized. The place and a role of transport in urban settlements are determined. An idea of geosocioeconological field of settlements is given. The generalized socioeconological parameter which formula includes assessment criterion of transport system is offered for the characteristic of a field. The proposition of low efficiency of transport system was proved mathematically after the analysis of assessment criterion of transport system. Ways of improvement of urban transport system functioning were planned.
