The problem of èkorekonstrukcii technological urban landscapes and the "critical" areas. Use an approach based on "bio-positive" image forming. Asked to describe the Visual and conceptual links between the "new" object and the natural environment. Biocompatibility of "object" and "context" is considered to be the "connectivity". We developed the seven levels of the biocompatibility of "engineered" object "and" context "in èkorekonstrukcii: volumetric-spatial, composite, plastic, decorative and functional, figurative (emotional and artistic), historical-cultural, communicative. on the basis of a set of information links. Represented a priority scale of "bio-compatibility" "object" and "context". Extreme positions of the scale: maximum compatibility and maximum differentiation "define policy options for design èkorekonstrukcii. Synthesized five methods (policies) based on èkorekonstrukcii information links an object context: a direct citation, innovations "in style", a loose combination of opposition, indirect direct opposition. A theoretical model of joint information fields "object" and "context". The model describes the results of complex architectural èkorekonstrukcii "critical" of the territory and its return to a sustainable State. The proposed method of description of "connectivity" can be used in the development of the "road maps" and "targeted" in forming strategies plans èkorekonstrukcii architectural environment of the South-Russian cities.

The article presents the results of an experimental research on the effect of the pulsating mode a capacitive heat exchanger with an active pipe part on the convective processes heated fluid. Described dignity capacitive heat exchangers. The research was conducted using a thermal imaging surveys. Compares two modes: stationary and pulsating. The method of experimental data processing, based on the analysis of fluid layers. A regression analysis allows to determine the dependence of the relative distribution of the temperature difference between the layers of fluid in the studied mode. The obtained regression equations were presented in the form of an exponential function and harmonic. The effect of pulsing regime on the process of convection in the upper quarter of the heating zone in a capacitive heat exchanger. The study showed the advantage of the capacitive heat exchanger with an active pipe part is often compared with the classical heat exchanger in part the speed of convective processes in the fluid to be heated.

In article the condition of a passenger transport complex of the Izhevsk city agglomeration is considered. It is noted that agglomeration includes a number of settlements of the neighboring regions. It imposes additional restrictions on development of all transport complex as it is necessary to agree in addition on the separate organizational economic problems relating to competences of local authorities. The main problems constraining development of a passenger transport complex from which are especially distinguished infrastructure, technical, administrative, and also tariff policy are shown. The package of measures on improvement of transport service of the population of city agglomeration is offered. Theoretically locates expected social-economic effekt.

for snow removal from roads used by different snow-clearing equipment. The efficiency of its use is determined by the road conditions. This is especially true for snow plows in settlements with elements of arrangement of road (curbs, sidewalks, road barriers, stopping points). In these circumstances widespread machine dumps. The ability to develop, manufacture and operation of dumps of snow plows on small and medium-sized enterprises defines their widespread use and a variety of designs. Promising to modernize the necessary conditions under heaps of snow removal from roads and sidewalks. The decision in this case take into account the comprehensive approach, comprising as an account of the influence of external factors - the operating conditions of the machine, and internal changes in the parameters of the machine. Analysis of the problem has allowed to hypothesize on the design of blade snow removal machines. In order to develop a scheme blade methodology for the study and design of experiments, the basic factors of influence on the resistance. The design blade for snowplows and virtual model to assess performance.
