World Bank
1. World Bank or International Bank for Reconstruction and Development is a multinational institution set up in 1947 to provide economic aid to member countries – mainly developing countries – to strengthen their economics. The Bank has supported a wide range of long-term investments including infrastructure projects such as roads, telecommunications and electricity supply; agriculture and industrial projects including the establishment of new industries, as well as social, training and educational programmes.
2. The Bank's funds come largely from the developed countries, but it also raises money on international capital markets. The Bank operates according to 'business principles' lending at commercial rates of interest only to those governments it feels are capable of servicing and repaying their debts.
3. In 1960, however, it established an affiliate agency, the International Development Association, to provide low-interest loans to its poorer members. Another affiliate of the World Bank is the International Finance Corporationwhich can invest directly in companies by acquiring shares.

                                                 Channels of Marketing
1. Individual consumers and corporate buyers are aware that thousands of goods and services are available through a very large number of diverse channel outlets. What they may not be well aware of is the fact that the channel structure, or the set of institutions, agencies, and establishments through which the product must move to get to them, can be amazingly complex.
2. Usually, institutions specializing in manufacturing, wholesaling, retailing, and many other areas join forces in marketing channel arrangements to make possible the delivery of goods to industrial users or customers and to final consumers. The same is true for the marketing of services. For example, in the case of health care delivery, hospitals, laboratories, insurance companies, and drugstores combine efforts in an organized channel arrangement to ensure the delivery of a critical service.
3. Therefore, marketing channels can be viewed as sets of interdependent organizations involved in the process of making a product or service available for use or consumption. Not only do marketing channels satisfy demand by supplying goods and services at the right place, quantity, quality, and price, but they also stimulate demand through the promotional activities of the units (e.g., retailers, manufacturers' representatives, sales offices, and wholesalers) comprising them.
4. The major focus of marketing channel management is on delivery. Producers of goods (including manufacturers of industrial and consumer goods, legislators, educational administrators and insurance companies) are individually capable of generating only form or structural utility for their «products».

Electromagnetism
1. Electricity and magnetism combine to form one of the fundamental forces of the universe – electromagnetism. The two constantly interact, and the relationship between them is one of the most important in physics. For example, an electric current passing through a wire creates a magnetic field; and if the lines of force around a magnet are cut by a passing object, an electric current will be produced.
2. Magnets are attracted to iron and to any material that contains iron. Magnets have two poles, a north pole and a south pole. Unmagnetized iron and steel have magnetic regions of atoms called domains that are jumbled up and point in lots of different directions. When iron or steel becomes magnetized, the domains become aligned and they all point in the same direction. One end of each domain points toward the magnetic north pole.
3. Electronics is a new branch of physics, and one that plays an increasingly important part in our lives. It is concerned with the use of electricity to produce signals that carry information and control devices such as computers. These devices contain electric circuits through which electric current flows. The controlling parts in a circuit are called components, and these include diodes and transistors. Components can amplify currents, switch them on and off, or change their direction.

Technology
1. Technology is the usage and knowledge of tools, techniques, crafts, systems or methods of organization in order to solve a problem or create an artistic perspective. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The human species' use of technology began with the conversion of natural resources into simple tools.
2. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.
3. Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions.

Marie and Pierre Curie knew that radium existed, but they had to prove it because a chemist believes in the existence of a new substance after seeing it, touching it, weighing it and finding out its atomic weight. They began working at that problem in 1898. Their task was to obtain pure radium. The way to separating radium was a difficult one. They could separate radium by treating large amounts of pitchblende.
In 1902 they succeeded in preparing a decigram of pure radium. Radium had something better than a beautiful colour, it was luminous. The discovery of radium gave them the possibility of discovering other radioactive substances.

                                                 Planned Economies
1. Planned economies are sometimes called «command economies» because the state commands the use of resources that are used to produce goods and services as it owns factories, land and natural resources. Planned economies are economies with a large amount of central planning and direction, when the government takes all the decisions; the government decides production and consumption. Planning of this kind is obviously very difficult and the result is that there is no society, which is completely a command economy. The actual system employed varies from state to state, but command or planned economies have a number of common features.
2. Firstly, the state decides precisely what the nation is to produce. It usually plans five years ahead. It is the intention of the planners that there should be enough goods and services for all. Planners are afraid to produce goods and services unless they are sure substantial amounts will be purchased. This leads to delays and queues for some products.
3. Secondly, industries are asked to comply with these plans and each industry and factory is set a production target to meet. If each factory and farm meets its target, then the state will meet its targets as set out in the five-year plans. You could think of the factory and farm targets to be objectives, which, if met, allow the nation's overall aim to be reached.
4. A major problem faced by command or planned economies is that of deciding what to produce. Command economies tend to be slow when responding to changes in people's tastes and fashions. Planners are likely to underproduce some items as they cannot predict changes in demand. Equally, some products, which consumers regard as obsolete and unattractive, may be overproduced.

Industries of the planned economies are set out production targets to meet in the five-year plan
A planned economy is a command economy with central planning and direction of the government.

Vacuum
1. Evangelista Torricelli produced the first laboratory vacuum in 1643, and other experimental techniques were developed as a result of his theories of atmospheric pressure. A torricellian vacuum is created by filling a tall glass container closed at one end with mercury and then inverting the container into a bowl to contain the mercury.
2. The quality of a vacuum refers to how closely it approaches a perfect vacuum. Residual gas pressure is a primary indicator of quality, and is most commonly measured in units called torr, even in metric contexts. Lower pressures indicate higher quality, although other variables must also be taken into account.
3. Vacuum became a valuable industrial tool in the 20th century with the introduction of incandescent light bulbs and vacuum tubes, and a wide array of vacuum technology has since become available. The recent development of human spaceflight has raised interest in the impact of vacuum on human health, and on life forms in general.

Composite Materials
1. Among the oldest and newest of structural materials are composite materials. It was discovered many years ago that two or more materials could be used together as one. Later it was proved that such a combination often behaved better than each material alone. Following this principle, clay and straw were combined to make bricks. For centuries composite materials remained virtually untapped. Only then monolithic materials, such as iron, copper were served for needs of an advancing technology. Recently it was a development of technology with coming of reinforced concrete, linoleum, plasterboard and plywood panels.
2. During the 1930s and 1940s light-weight honeycomb structures, machine parts made from compressed metal powders and plastic reinforced with glass fibers became commercial realities. These developments marked the beginning of the modern era of composite engineering materials. It was mentioned growing and using composite materials. Nevertheless, the emergence of a strict discipline and technology of composite materials is barely 20 years old.
3. There are two major reasons for the current interest in composite materials. The first is the demand for materials that will outperform the traditional monolithic materials. The second and more important in the long run, is that composites offer engineers the opportunity to design totally new materials, with the precise combination of properties needed for a specific task. Although new composites are usually more costly than conventional materials, they can be used more sparingly, because of their superior qualities.
Определите, какое утверждение соответствует содержанию текста.

Composite materials cannot be used sparingly.
Light-weight honeycomb structures were invented in the 21st century.
Сomposite materials are among the newest of structural materials.
The combination of materials works better than each of them alone.

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.

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.
