Metals are materials most widely used in industry because of their properties. The study of the production and properties of metals is known as metallurgy.

The separation between the atoms in metals is small, so most metals are dense. The atoms are arranged regularly and can slide over each other. That is why metals are malleable (can be deformed and bent without fracture) and ductile (can be drawn into wire). Metals vary greatly in their properties. For example, lead is soft and can be bent by hand, while iron can only be worked by hammering at red heat.

The regular arrangement of atoms in metals gives them a crystalline structure. Irregular crystals are called grains. The properties of the metals depend on the size, shape, orientation, and composition of these grains. In general, a metal with small grains will be harder and stronger than one with coarse grains.

Heat treatment such as quenching, tempering, or annealing controls the nature of the grains and their size in the metal. Small amounts of other metals (less than 1 per cent) are often added to a pure metal. This is called alloying (легирование) and it changes the grain structure and properties of metals.

All metals can be formed by drawing, rolling, hammering and extrusion, but some require hot-working. Metals are subject to metal fatigue and to creep (the slow increase in length under stress) causing deformation and failure. Both effects are taken into account by engineers when designing, for example, airplanes, gas-turbines, and pressure vessels for high-temperature chemical processes. Metals can be worked using machine-tools such as lathe, milling machine, shaper and grinder.

The ways of working a metal depend on its properties. Many metals can be melted and cast in moulds, but special conditions are required for metals that react with air.

the most difficult. For the lawyer it is a question whioh present special problems for a variety of reasons. The punishment of a criminal is a combined operation of Parliameny, the courts, and the administration. The range of penalties whioh may be imposed is in most cases set by the legistature, which fixes the maximum sentences for different offences. For the majority of offences only the maximum penalty is prescribed by law, so that the court is left free to select in each case the appropriate sentence.

if the accused has never before been convicted of crime, the sentence is not likely to be severe, unless the crime is one of violence. first offenders are usually treated with sympathy. if, on the other hand, the accuused man has a long record of convictions, the judge will pass a more severe sentence.

after the court has selected what sentected seems suitable, the carrying out of this sentence falls to the lot of those who administer the penal system.

one result of this is that once sentence has been passed, the courts are no longer concerned with the offenders fate:their task is concluded

To be sure, the mining industry has been environmentally slow.
Although great strides have been made, the mining industry generally has been very slow to do a better job.
Toward a Solution
The solution to this problem is to develop new approaches to mining that, individually and collectively, serve to reduce dramatically its impacts – while at the same time improving its efficiency and economics. Economic improvement is critical, because if impact reduction does not involve economic benefit it will not be willingly and widely adopted. Fortunately, there are a number of promising strategies for reducing mining's impact and improving its balance sheet. For example:
Identify and Develop New Mining Methods.
It is not hard to envision new methods of mining that would have less impact on the environment and would reduce or eliminate scarring of the land. For example, perhaps techniques as diverse as directional drilling in the petroleum industry and for that matter laparoscopic surgery in medicine could be applied to recovering valuable metals and minerals while dramatically reducing the amount of rock that must be moved. At the very least such an approach is suggestive. Take a systems approach to planning projects. If projects are planned from the outset with a low impact perspective, it should be possible to avoid problems or turn potential problems into assets. For example, open pits can be used as lakes or reservoirs if a project is properly planned. Perhaps post-recovery uses could be found for underground mines if such uses were taken into account at the design phase.
Create an Environmental Certification Agency for New Mining Projects.
A key objection to mining from the environmental industry is that they have little faith in the outcome of mining operations. A certified project would eliminate doubt. Approved projects could proceed faster, thereby rewarding good mining practices. It's time to make mining work in the environment.

Switzerland, they can use the money they earn to import

Swiss chocolate — or to pay for Kuwaiti oil or a vacation in Hawaii. The basic idea of

international trade and investment is simple: each country produces goods or services that can be

either consumed at home or exported to other countries.

The main difference between domestic trade and international trade is the use of foreign

currencies to pay for the goods and services crossing international borders. Although global trade

is often added up in U.S. dollars, the trading itself involves various currencies. Japanese

videocassette recorder is paid for in German marks in Berlin, and German cars are paid for in

U.S. dollars in Boston. Indian tea, Brazilian coffee, and American films are sold around the

world in currencies as diverse as Turkish liras and Mexican pesos.

Whenever a country imports or exports goods and services, there is a resulting flow of funds:

money returns to the exporting nation, and money flows out of the importing nation. Trade and

investment is a two-way street that, with a minimum of trade barriers, usually makes everyone

better off.

In a interlinked global economy, consumers are given the opportunity to buy the best products at

the best prices. By opening up markets, a government allows its citizens to produce and export

those things they are best at and to import the rest, choosing from whatever the world has to

offer.

Some trade barriers will always exist as long as any two countries have different sets of laws.

However, when a country decides to protect its economy by erecting artificial trade barriers, the

result is often damaging to everyone, including those people whose barriers were meant to

protect.

The Great Depression of the 1930s, for example, spread around the world when the United States

decided to erect trade barriers to protect local producers. As other countries retaliated, trade

plumpered, jobs were lost, and the world entered into a long period of economic decline.
