One of the most important forms of educational process
January 28, 2012 | 
Author A research student is one of the most important forms of educational process. Scientific laboratories and workshops, student scientific society and Conference-this allows the student to begin a scientific work, find like-minded people on it, which you can consult and share the results of their research. Either way, research by all students. Writing essays, research paper writing, theses cannot be without any, even the simplest research.
Student engaged in scientific work, is responsible only for themselves; only by himself on the topic studies, time commitment and not least, and will be accomplished at all. Spending their own time, the student develops such important for future research quality as creative thinking, responsibility and ability to defend its point of view. The teacher requires good attention and support, without which the student, especially at the junior courses will not want to (and just could not) be “boring science”, which seems to almost any discipline in the early stages of its development.
It should be noted that it is primarily on social sciences such as political economy and economic theory, although the exact sciences knowledge even one year ago might be outdated. So long most teachers leaning towards the idea that their goal is not to compel students to remember a lecture, and then tell it in a practice session or exam and use, and teach them to learn throughout life they update their own stock of knowledge. But the problem is that many students on a variety of reasons (from simple laziness to mental disorders) can approach the training creatively.
History of development of polymeric pipes
Today on the market of construction materials is a large assortment of plastic pipes. And if 10 years ago in the minds of our citizens there were convinced that the trumpet can be only railway, now the situation has changed radically. Over the years polymer pipes deservedly won great popularity.
PEX pipes should be used for hot and cold water supply, central heating and floor heating systems. They are resistant to chemical substances that are not subject to corrosion, low surface roughness and smoothness of the wall prevent deposits on internal surfaces. PEX pipes do not emit harmful substances, does not alter the taste of water.
Polyethylene is the only of the thermoplastic materials capable of molecular chains in a mesh structure. PEX pipe made of chemically modified polyethylene. Tailored polythene, in comparison with usual, is more resistant to high temperature and keeps the elevated mechanical properties; characterized by good shrink tape. PEX tubing material is high-density polyethylene and linear structure and high strength.
Multilayer pipe based on cross-linked, due to the presence of ethylene vinyl alcohol layer of aluminum or Al, securely protect transported heat from penetrating through the boundary of the tube, which causes air oxygen corrosion and premature failure of heating elements and devices of the heating system. PEX pipes are connected by brass fittings that represent a wide range of products and are divided into 2 main categories:
- PEX fittings-PEX (PEX to connect among themselves)
- PEX fittings-thread (for connections to other parts of the system through the traditional tubal thread)
PEX do not need to calibrate, braze, cooking, glue, which allows you to save time and reduce the cost of installation. Thanks to a great length of the pipe in coils, installation is done with a minimum number of connections. Scratches, twists do not affect their life.

Housing construction
Citizens offer to form non-profit associations and to engage in housing construction. Between the employer and the contractor will not be intermediate developer interested in profit. As a result, prices can be maintained at the level of the cost. This form of social housing exists in many countries around the world. However, in most cases, real estate remains the property of such associations and does not move to private individuals. These structures will receive land free of charge, the authorities will take care of engineering networks, and housing will provide almost nothing, but to enter into such a co-op can only applicants and benefit recipients. Privatize the apartments they fail and, hence, cannot be and speculation.
Members of the public cooperative after foreclosure share become homeowners, but can remain in the cooperative for joint management of the homeland. Without the support of professionals are not citizens. Operators will be created for them that will help in the Organization and work of the cooperative. If social form to take its place on the market and provide shelter, they will be able to set some price guide and market commercial housing.
The system of housing cooperatives offers to return to the head of the company “housing initiative”. “The issue we struggle for a long time, but the further you go, the more we come to a standstill. Auctions on decrease in the area of housing and public utilities have failed. It’s time to stop reinventing the wheel. Everything new is well forgotten old, housing construction cooperatives has not been too readily available, but remain completely understandable. They should be returned. The co-operative system formed and kept prices. It is worth examining its own and foreign experience and do not walk on the same rake.
Investment contract
Build a House is from the perspective of the buyer is only half done. Block House is six months, monolithic two-three years. Housing construction is carried out on different schemes of relationship developer and administration. The greatest freedom from micro-power structures giving scheme, under which the developer during the auction to buy the right long-term rents station under construction. In this case, the ownership of the building can be registered within six months after commissioning and defects.
Most of the objects (excluding real estate) are based on investment contracts. There are two basic varieties. According to the first, an investor pays off city construction charges: road, kindergarten, school, heat substations, etc. According to the second, an investor is paying the contractual rate built space-both residential and non-residential or their monetary expression. In both cases, the appearance of ownership does not start after the Act of entering of object in operation, and after the Act of realization of the investment contract (the closure of the investment contract). That is, built roads, schools and substations.
And if we are talking about “not a very experienced developer, unpleasant surprises after the acquisition of the project it is unavoidable. As a rule, do not have Metropolitan experience Developers bought the relative advantages of the project. But you need to understand that the “tasty” price is likely to charge that will result in unplanned expenditures.
Today in one of the elite buildings people live without hands documents to property, as officials still ponder the fate of non-residential basement. Therefore, real estate buyers in this House there is neither evidence nor the promised infrastructure on the ground floors. How long this situation, no one knows, even more so now when prices increase and there is the temptation to get from developer more tomorrow than today.

Even if you hire to assist working-you need to know what they do, monitor the process to understand, not whether they allow the gravest mistakes.
