ENVIRONMENTAL PROTECTION PROBLEMS

The protective layer of the Earth, the ozone layer, which protects the Earth from the sun's destructive UV (ultraviolet) rays, is being damaged by CFCs (chlorofluorocarbons). They are released by the daily use of industrial and household products: refrigerators, air conditioners, cleaning chemicals, food packaging. The «ozone hole» allows more UV rays to penetrate to the Earth. It increases the risk of skin cancer, weakens the immune system of people. Besides, UV rays influence the oceans, the growth of plankton, an essential part of the marine-life food chain in the negative way; reduce economically important crops (rice, cotton, soy beans).

Deforestation could cause one forth of all species on earth to vanish in the next 25 years. These forests in Amazonia, South-East Asia and West and Central Africa are being destroyed at an alarming rate of 42 million acres per year.

The protection of natural resources and wildlife is becoming a political program in every country.

United Nations Environment Program (UNEP) concentrates its activities on these issues.

The 5th of June is proclaimed the World Environmental Day by the UNO and is celebrated every year.

We are obliged to remove factories and plants from cities, use modern technologies, protect and increase the greenery and broaden ecological education. These are the main practical measures, which must be taken in order to improve the ecological situation. Some progress has been already made in this direction.

MAIN BRANCHES OF ENGINEERING

Engineering, much like other science, is a broad discipline which is often divided into several sub-disciplines. These disciplines concern themselves with differing areas of engineering work. Although initially an engineer will usually be trained in a specific discipline, throughout an engineer's career the engineer may become multi-disciplined, having worked in several of the outlined areas. Engineering is often characterized as having four main branches:

Chemical engineering – The exploitation of chemical principles in order to carry out large scale chemical process, as well as designing new specialty materials and fuels.

Civil engineering – The design and construction of public and private works, such as infrastructure (roads, railways, water supply and treatment etc.), bridges and buildings.

Electrical engineering – a very broad area that may encompass the design and study of various electrical and electronic systems, such as electrical circuits, generators, motors, electromagnetic/electromechanical devices, electronic devices, electronic circuits, optical fibers, optoelectronic devices, computer systems, telecommunications and electronics.

Mechanical engineering – The design of physical or mechanical systems, such as power and energy systems, aerospace/aircraft products, weapon systems, transportation products engines, compressors, kinematic chains, vacuum technology, and vibration isolation equipment.

Historically, naval engineering and mining engineering were major branches. New specialties sometimes combine with the traditional fields and form new branches.

In Political science the term engineering has been borrowed for the study of the subjects of Social engineering and Political engineering, which deal with forming political and social structures using engineering methodology coupled with political science principles. Financial engineering has similarly borrowed the term.

FAMOUS LONDON ARCHITECT

Before the Great Fire there were 108 churches in the City, but only 20 survived the flames. It was decided to rebuild 51, and this monumental task was given to Sir Christopher Wren (1632 - 1723).

Wren’s masterpiece was St Paul’s Cathedral, but each church was designed with the same care so that no two were alike.

During the Second World War nearly all Wren’s churches were destroyed or damaged. Most were reconstructed, and of the 39 churches in the City, 23 are by Wren.

Inigo Jones (1573-1652) transformed English architecture and introduced a Classical style whose influence was to last for nearly 300 years. In 1617 he was began to build the Queen’s House at Greenwich, and in 1619 was invited by James I to build the Banqueting House for Whitehall Palace.

Jones was also responsible for Covent Garden, which originally took its name from the convent that stood on the site in the Middle Ages. Here Jones based his design on the style of an Italian piazza and created London's first real square. The Garden flourished in the 17th century as the residential area of the rich. It was King Charles' II favourite haunt, a place of entertainment of all sorts.

In the 18th and 19th centuries Covent Garden became known for its fruit and vegetable markets.

In 1974 the market was moved to a new site in Nine Elms, and Covent Garden has become a tourist attraction with continental-style restaurants, bars and clubs.

Another of London's great builders is John Nash (1752—1835). He enlarged Buckingham Palace and gave it a grand archway, called the Marble Arch, which was moved in 1851 to Hyde Park, where it still stands.

Today Buckingham Palace is the official residence of the Royal Family. The Flying of the Royal Standard on the palace proclaims that the Queen is in Residence. The Changing of the Guard is a very popular tourist attraction.

FAMOUS LONDON ARCHITECTS

When Queen Victoria came to the throne, a new era brought the first major change in architectural styles since the days of Inigo Jones.

When the railways came to London the Victorians built railway stations. They were so magnificent, that they looked like palaces. Among the most beautiful ones are Euston Station, King's Cross Station and St Pancras.

The Victorian Gothic style dominated in London's buildings until the end of the century, and can still be seen in many civil, public and commercial buildings. One of its strongest supporters was Prince Albert, and after his death in 1861 a memorial to him was designed by Sir George Gilbert Scott. A bronze statue to the prince looks across Kensington, the borough that he made into London's centre for the arts and sciences. Prince Albert's other London monument is the Royal Albert Hall, opposite the memorial, which was opened in 1871.

The trend in architecture during the first 20 years of the 20th century was largely a continuation of the Victorian style.

After the Second World War London, and particularly the City, underwent its biggest redevelopment since the Great Fire. There arose concrete and glass skyscraper blocks, towering above St Paul's Cathedral. London had reached its acceptable boundaries, and building land was very expensive. So commercial buildings reached for the sky, matched by high-rise blocks of flats in the East End. In 1969 the Post Office Tower at 580 ft was the tallest building in Britain. It has a familiar name — "pie in the sky", and a restaurant revolves at the top.

The latest contender for the title of London's tallest building is the 600 ft National Westminster Bank building in Bishopsgate.

The face of London changes, as it must if the capital is to remain alive. But its past is still there for all to see — in streets and buildings that portray almost 2000 years of history.

COMPUTERS AND THE INTERNET

Computer is an electronic device that can receive a program (a set of instructions) and then carry out this program by calculating numerical information.

The modern world of high technology is possible mainly due to the development of the computer. Computers have opened up a new era in manufacturing by means of automation, and they have enhanced modern communication systems.

Personal computers are also called microcomputers or home computer. The most compact are called laptops. They are portable and work on built-in batteries.

Personal computers are designed for use at homes, schools, and offices. At home they can be used for home management (balancing the family finances, for example) and for playing computer games, watching films or listening to music. Schoolchildren can use computers for doing their homework and many schools now have computers for independent learning and computer-literacy studies. In the office personal computers may be used for word processing, bookkeeping, storage and handling of necessary information.

The Internet and its technology continue to have a profound effect in promoting the exchange of information, making possible rapid transactions among businesses, and supporting global collaboration among individuals and organizations. More than 100 million computers are connected via the global Internet in 2000, and even more are attached to enterprise internets. The development of the World Wide Web leads to the rapid introduction of new business tools and activities that may lead to annual business transactions on the Internet worth hundreds of billions of dollars.
