Plastic Materials
1. Plastic materials are not found in nature. Plastic is formed by extrusion or injection molding under very high pressure. It can be molded into any desired shape. Organic plastics are divided into two general groups: thermosetting and thermoplastic. The thermosetting group becomes rigid through a chemical change that occurs when heat is applied. These plastics cannot be remolded. The thermoplastic group remains soft at high temperatures and must be cooled before becoming rigid. This group is not used generally as a structural material.
2. Plastics are rapidly becoming important construction materials because of their great variety, strength, durability and lightness. Plastics are light. The benefits of light weight coupled with good strength and absence of corrosion offer tremendous potential as alternatives to traditional building materials. A given volume of polythene weights less than one-eighth of an equal volume of iron and less than half of the same volume of aluminum.
3. Plastics are used in the industry and in the household: from rockets and electronics to toys and house ware. Plastic products offer many advantages over the materials they replace, such as ease of handling, lower maintenance costs and rapidity of assembly. The insulation and dielectric properties of plastics led to their early use in the electrical engineering industry, which was followed by special application in mechanical engineering.
4. Using of plastics as materials for a construction in the form of sheets, rods or tubes is substituting the conventional metals. Plastics offer a lot of properties for the designs. Plastics have now been developed to such an extent that they can be applied to almost every branch of building, from the laying of foundations to the final coat of paint.

Privatization
1. Privatization is the process by which the production of goods or services is removed from the government sector of the economy. This has been done in a variety of ways, ranging from the public sale of shares in a previously state-owned enterprise to the use of private businesses to perform government work under contract.
2. The leader in this innovative strategy was the Thatcher government of Great Britain from 1979 to 1990. Previous governments had tried limited denationalization, which is the restoration of nationalized enterprises to their previous owners, but with limited success. Privatization involved totally new owners. In some cases the state enterprises that were «privatized» had never been in the private sector.
3. Governments all over the world were confronted in the seventies by the problems inherent in state ownership. Because state-owned companies have no profit motive, they lack the incentive that private companies have to produce goods that consumers want and to do so at low cost. An additional problem is that even if they want to satisfy consumer demands, they have no way of knowing what consumers want, because consumers indicate their preferences most clearly by their purchases.

I study at the Cooking Department of the Moscow College of Technologies and Design, so I will be a cooking and catering professional: a cook or technologist.
Every school year we do practice work for 2–3 months. This year our groups have done their practice at the Golden Palace restaurant. This is a large restaurant, which is open 24 hours a day since it is the restaurant by the casino with the same name.
There are three departments within the main shop there – a cold shop, a hot shop and a pastry-cook’s shop. Salads, snacks, sandwiches, cuts of cold meat and fish and desserts are made in the cold shop. Soups, hot meat and fish dishes and sauses are prepared in the hot shop. In the pastry-cook’s shop they make tarts, patties, fancy cakes, etc.
