Electromagnetic Induction Term Paper:
Electromagnetic induction is the phenomenon of the creation of electric current in closed circuit during the change of the magnetic flux which goes through it. Electromagnetic induction was discovered by Michael Faraday in 1831 after the great number of experiments in the sphere of magnetism. In 1820 it was discovered that electricity generates magnetism, so that it is quite possible that electricity and magnetism are interconnected and magnetism can generate electricity as well. This idea existed for about ten years in the head of Faraday and due to the numerous experiments he managed to prove it and discovered the phenomenon of electromagnetic induction.
He discovered that the electromotive force, which occurs in closed conducting circuit, is proportional to the rate of change of magnetic flux through the surface, limited by this circuit. Continue reading
Term Paper on Firewall:
A firewall is a device or a group of devices which have been designed to accept, decline, cipher, and let the whole computer traffic through proxy between the areas of different security according to the set of rules and other criteria. Firewall can look like a single device (the so called router, which provides the user with the access to the Internet), the software which is installed on the personal computer and proxy server.

Stateless firewalls are characterized with simple filtration and they do not follow the current connections and filter the stream of data on the basis of the static rules. Continue reading
History of World Cup Term Paper:
The history of World Cup is connected with the football tournaments which take place every four years in one of the countries in the world. The history started in 1928 when Jules Rimet, the President of FIFA, decided to make football one of the most popular games of all times and suggested to stage the international tournament in 1930 in Uruguay.

Biofuels Term Paper:
Biofuels are the fuels based on organic materials, which are used for the production of energy. The most well-known biofuels are wood, alcohol and wastes. In comparison with the most popular types of fuels (oil, gas, coal, etc) which are exhaustible, biofuel is the renewable type of energy, because it is produced during the term of no more than ten years. Biofuels contain about 80% of the products which are the result of the activity of the live organisms – animals and plants. The most serious advantage of biofuel is that it consists of the organic materials and it is not dangerous for the environment. The main similarity between biofuel and oil or coal is that biomass is the form of the accumulation of the solar energy – the energy of the Sun is caught through the process of photosynthesis during the growth of plants.

Term Paper on Green Chemistry:
Green chemistry is the branch of chemistry which is characterized with the reduction of the negative impact of the chemical substances on the environment and human life.

Moreover, the substances are even expected to do more good than harm, curing illnesses and helping people in their activity. The concepts of green chemistry appeared at the beginning of 1990s when people understood the importance of production of healthy and safe products.

Burglary Term Paper:
Burglary is the action of the illegal entry into the private house and it is considered to be a crime.
Burglary is not just the entry into the building, but also the kind of offence characterized with stealing the property of the third people – the owners of the building.

Microscopy Term Paper:
Microscopy is the study of small objects with the help of a microscope. Microscopy is divided into several branches which differ according to the methods of the research and appliances used for the process. For example, there is optical microscopy, electron microscopy, X-ray microscopy, flash diffractive imaging, etc. and all these devices are used for the enlargement of the picture of the object under research. First of all microscopes were the optical devices which used the sunlight and worked on the same principle as the human eye, but their power was too limited, because the best optical microscope can enlarge the object 2000 times. Of course, there are organisms and objects which require more powerful devices to be seen by the human eye, so electron microscope was invented for this purpose and can enlarge objects in 100 000 times and even more.
