Protect the surface of the concrete floor
To protect the concrete floor, which is operated in the normal mode, or is subject to wear in areas with high traffic, there are several ways to protect the surface.
   Comparable ways: their cost, appearance and ability to perform the task to protect.
   In this article, we consider three ways to finish and protect the floor. Each of them has its advantages and disadvantages.
   Thin fil...

Finishing compositions based on water glass. Part 3
When used as part of exhaustion moderator comes coagulation and solidification of liquid glass. However, due to the presence in the composition of Portland cement with a finishing time is an increase strength of the coating due to hydration of cement minerals. Thus from colloids formed during the coagulation liquid glass are actively assigned to the water for hydration of cement, a porous media formed tumors filled Portland cement, which leads to...

Geophysical processes primers and security. Part 5
In the center of Moscow can distinguish vertical structure comprising a crashing into the Earth`s crust magma elongated cylinder (Fig. 2) [5]. In the center section marked lack of extensive vertical zone converted waves ("blind spot"), going from the depths of 70-80 km to 7.5 km. Such "blind spots" are characteristic of the earth`s crust with the introduction of monolithic dense mantle rocks such as gabbro, diabase, etc. In such a zone Tashkent e...

Finishing compositions based on water glass. Part 1
The quality of the decoration of buildings for new construction and reconstruction depend not only on their aesthetic, but also the operational parameters, as good-quality finish - a guarantee of durable service basic designs, long maintenance-free operation, the costs for maintenance and care. Traditional binders used for the production of finishing compositions, liquid glass is widely used, but it has some drawback: coatings based on it gaining...

On possible amendments to the equation Griffiths
Griffith presented a picture of destruction allowed to formulate the problem of determining conditions of the beginning of crack propagation and find its general solution.
   As seen from the above schemes, in the process of crack propagation material directly adjacent to it "coasts" unloaded relaxes. This means that the stress and strain it decreases, and the elastic energy stored earlier in this area of ​​the body is re...

 Technology  formation  of  urban  formations

1. Composition
   Formation technology urban formations developed in the following directions:
   monitoring the progress of the control system, "General scheme of settlement of the Russian Federation" with the operational introduction of the results of scientific support for the necessary adjustments;
   development of a "General Scheme" development programs of regional settlement systems, primarily for the crisis regions of northern areas, zones of concentration of single-industry communities, particularly in coal mining areas, oil and gas, and other areas of the profile;
   To develop a sustainable development of cities and settlements in the territory of the Russian Federation;
   Developing technologies and determine the direction of a set of practical measures that will ensure the sustainable development of the modern village, rural settlement systems and small towns;
   ensuring a balanced socio-economic development of regions and reducing the prerequisites for interstate migration;
   Development of technology determine prospects for economic development and economic infrastructure optimization city-base, employment issues in the field of conversion schemes of settlement, cities and metropolitan areas;
   technology for creating the concept of transport support cities and territories in the complex scheme of transport capable of optimizing operation of the transport infrastructure;
   technology for creating physical infrastructure development programs using the achievements of scientific and technical progress in the settlement systems, cities and towns;
   improving the enforcement of domestic urban planning subsequent improvement of the Code of practice on the basis of research design and implementation of legal instruments in the field.
   2. Purpose, basic functional parameters:
   Development based on analytical studies and scientific research guidelines state planning policy, new Russia, defining a mechanism for its enforcement, the creation of its scientific support;
   improving the governance structure urban development activities in the center and in the field, ensuring economic control over executive discipline;
   Addressing the issue of providing funding for the development of programs of urban development systems of settlement agglomerations, cities;
   concentration of domestic experience in urban development in Russia the main provisions of domestic theory of modern urban development - scientific support base of practical work;
   scientific and technology determine a reliable forecast settlement systems, agglomerations, cities and settlements in solving the main problem of the next few years in the business of bringing order quantitative transformation of the Soviet period in the national urban development as a response to the social order - "Construction of Russia";
   greening of developing all kinds of software development systems of settlement, agglomerations, cities and settlements. Technology development of special programs and activities on the Elimination of urban development funds crisis ecological situations in the regions and cities.
   3. Scope:
   the proposed formation of urban technology systems should be addressed to all levels, structures, institutions and organizations involved in addressing the country`s development, resettlement and settlement systems of all kinds, inherent in urban development programs, master plans, regional planning schemes and other long-term plans;
   Considering that the urban development as a special type of activity combining possibilities, considering the interests of coordinating the efforts of many sectors of the economy, is aimed at providing national, national interests, is essentially nadotraslevoy category, urban technology as a means of scientific support of public policy should be relegated and all levels governance in the country, including the government, the State Duma, the Federation Council, the governance structure of the Federation, local authorities, as well as RAS, branch academies state status and other organizations.
   4. Basis for Selection
   National economic significance of the developed technologies to the following factors:
   the need for rational and economic use of resources of all kinds in one of the largest countries in the world, has huge natural resources, for use in the future that will require huge amounts of money and effort;
   elimination of junk costs by preventing urban errors caused by ignorance as possible adverse effects, and in direct violation of state discipline in deviations from accepted into the program decisions;
   cost savings in the management of territorial resources of cities and settlements with the rejection of territorial expansion is widely used in contemporary practice, which caused traffic problems stretched utilities, increased heat loss;
   more efficient use of existing areas with the revision of standards and increasing density housing in areas of mass building reconstructed past years while strengthening the system of green spaces, recreation, sports, at the threshold of the house;
   ensuring the reconstruction method attractiveness of cities and regions of the individual to increase investment and number of investors, including foreign ones;
   improving the quality of the urban environment as a means of improving urban settlements and the quality of life, including both the comfort of living, full service and improving the aesthetic quality of buildings and improvements;
   improvement of management practices and the formation of the material and spatial, artificially created environment for effective labor, a healthy life, a good rest man, including in the process of local government;
   further effort on the basis of the Town Planning Code law for urban development.
   5. Status and trends of development
   Current state of urban affairs should be considered a crisis. Completely eliminated pre-existing quality management system development and implementation of urban development programs, settlement systems, agglomerations, cities and settlements. There is no state budget financing development projects of regional planning, master plans, detailed planning projects. Exclusion from the jurisdiction of local architecture of land issues and weakened urban planning discipline, which ultimately can not but lead to serious losses, especially in the urban environment and quality of life and health of people.
   Many architectural authorities generally passed to the committee structure on land use or real estate departments. Having lost their lead, research and design institutes lose frames specialists city planners, although earlier starved their deficit.
   Misunderstanding state, national values ​​of urban development activity manifested in the creation of the Ministry of land, construction and housing and communal services. Fortunately, the federal government has rectified the situation by restoring State Building. The challenge now is to strengthen his powers as nadotraslevoy structure with the transfer of its divisions of land issues in cities and towns, just as it is determined in a number of developed countries.
   Example Moscow, preserved even in a reduced funding from the city budget constant work on the master plan shows the required level and quality of implementation of urban development programs. It is possible to preserve and frames. Appropriate, following this example, restore them to the new conditions and new forms of urban business in the country as one of the conditions of formation of the New Russia.
