Vacation on the Volga River – a beautiful nature, fishing and swimming in summer, skiing and evenings by the fireplace in winter. Beautiful nature makes each unique recreation center on the Volga. Downstream recreation can be combined with medication. Here, in Ulyanovsk, Samara and Saratov regions and Tatarstan, there are many resorts and recreation complexes. Recreation center on the Volga River in its lower course – is not only a wonderful nature, but almost unlimited opportunities for an active pastime, and, above all, for fishing. Especially good place is the delta of the Volga, and fishermen from one year to gather in the region of , where services for the organization of fish Fishing offers each recreation center. Volga is poured on 500 channels, tubes and small rivers, forming the largest river delta in Europe. These places are famous not only fish, but the unique flora and fauna.

However, and middle Volga no less beautiful and abounding. Any recreation center here to offer winter and summer houses, almost everywhere there are saunas and baths, space and equipment required for sports. Here, as in the Volga delta, have opportunities for fishing, including ice fishing. A width of the river reaches forty kilometers. For example, a recreation center Byl "in the Ulyanovsk Volga spreads to forty-two miles. Recreation center on the Volga River most well-equipped and have a full range of amenities. Visitors are accommodated in cabins, wooden lodges or comfortable hotel rooms. Almost everywhere it is possible to stay on full or Partial pension (that is, with meals or two meals). Recreation center on the Volga often offer their customers a tour, not only in nature reserves, but also in the nearby town. Such services are particularly interesting if the recreation center is located near the historical monuments in Kostroma, Uglich, Yaroslavl, Volgograd.

Industrial Mechanics Wear

Posted: under News.

Wear in any material evidence of an effect of wear is nothing that the release of particulate material by some kind of agents that can have any number of sources. In the case of metals it can be said that most cases wear occurs primarily for two reasons corrosion and friction. Corrosion that develops in metals as these have to go back au natural state, which is in the form of oxide, so it can be said that the effort to avoid it is almost against "nature", according to this fact, therefore, the only thing you can do is minimize the effects of it. Usually we hear the expression "has been or is rusting" in reality is not entirely accurate, but it reflects the above, the metal is forming oxides, the phenomenon is of such magnitude that organizations approach it as one of its main tasks maintenance and represents a very important item in the cost of this activity. In general, we can say that, given by migration of electrons from an element called the anode, which is oxidized to another called cathode is reduced, so that this phenomenon is always necessary verified the presence of three components, the anode or cathode and electrolyte conduction through this is the more common, is corrosion and corrosion variants partial pressures and salt corrosion activity differently. The means to prevent it or avoid it are numerous and may involve actions ranging from the very design of the metal, its geometry, material type surface hardness, etc to the application of the same armor, it is interesting to note that the most used, is, the same oxide layer that forms immediately to the bare surfaces, confining the moisture to the outside of it, as is the case of sodium oxide coating that forms in the material immediately after cutting, or opaque roof that appears on copper after machining, it is of stainless steel oxide chromium and nickel, which are very sticky which gives it protection from friction can say that occurs primarily by lack of lubrication or by having a very poor, since no lubricant vast place, but must be the appropriate, therefore identify two possibilities, hydrodynamic lubrication is that which flows between the components and has a direct relationship with the speed of this flow generating a film of 5 microns and Elastohydrodynamic which has a thickness of 2 microns and has to UNTOC do with the lubricant, the first is fast-moving items, and the second those who have high pressures and low speeds, what is required in both cases is to avoid micro-welding at the points of cash.

For fixing the walls of pits of the underground parts of tall buildings can be used sheet pile walls, the walls of discretely arranged pile of supports to zabirkoy ‘wall in the ground’, the wall of , secant and screw piles and other methods of design and construction of fences, ensuring the stability of the sides of pits being built facilities, selected according to their depth and dimensions, physical and mechanical characteristics of soil, amount and nature of the load on the curb, technological equipment and economic indicators. 4.17. When using bored piles as foundation pillars of high-rise buildings should pay particular attention to ensuring high-quality stripper bottom of the borehole before it is concreting and reliable bearing piles to the current carrying layer of soil. In the case of sinking wells in the unstable soil beneath the mud should include activities (eg, special bookmark intravenous tubes) for additional grouting piles heels to ensure the quality of contact with the ground plate. 4.18.

When the device of multi-storey underground facilities for high-rise complexes should consider their construction method ‘top down’. In this case, the passage of soil for the next device underground floor is the small-sized earth-moving equipment from the previous ceiling. Exterior walls of the underground floors performed in a ‘wall in the ground’ and are simultaneously guard unearth the pit, and spacer fence system is included in the design of the overlap between the underground floors. Issuance of the developed soil at surface through openings left in the overlap. Production work on the method of ‘top down’ only permitted subject to agreement of technical documentation, in particular referred to the technological Regulations (Section 4.10), with the organization, which is the author of the project works of the zero cycle, and the positive resolution of geotechnical expertise. 4.19. When carrying out the zero cycle of tall objects to be waged the following technical documentation: general journal papers in the form prescribed snip 1.12; special journals for certain types of work (eg, piling, compacting foundation soil, etc
