Hydrogen
Hydrogen Since the beginning of the scientific revolution in the early nineties the mankind looks for an energy source that is clean and renewable; solution of this problem would be probably the most common thing in our life - WATER. Water consists of two chemical elements, hydrogen and oxygen. Each molecule of water consists of two hydrogen (H2) atoms and one oxygen (O) atom. Chemical binding between these three atoms is very stable and strong. Therefore, the reaction of hydrogen and oxygen is

Nuclear Energy
Nuclear Energy Nuclear Energy Nuclear energy-This is energy that binds together components of an atomic nucleus. This is made by the process of nuclear fission. Nuclear fission is produced when an atomic atom is split. The way nuclear pore is made is in a nuclear reactor, this is most likely located in a nuclear power plant. the fission that is produced is when a heavy element splits in half or is halved into two smaller nuclei, the power of the fission is located by the rate of the splitting of

Principles of Heat Treating of Steels
Principles of Heat Treating of Steels Principles of Heat Treating of Steels A steel is usually defined as an alloy of iron and carbon with the content between a few hundreds of a percent up to about 2 wt%. Other alloying elements can amount in total to about 5 wt% in low-alloy steels and higher in more highly alloyed steels such as tool steels and stainless steels. Steels can exhibit a wide variety of properties depending on composition as well as the phases and microconstituents present, which

Thailand Political Culture For us to be able to study political culture, it is imperative that we first learn how to define it. Political culture refers to the attitudes, beliefs and values, which underpin the operation of a particular political system. These were even seen as including the knowledge and skills about the political system, positive and negative emotional feelings towards it and the evaluative judgments about that system.

The Himalayas along China's southwestern frontier
The Himalayas along China\'s southwestern frontier with India are the world\'s tallest mountains. China\'s greatest river, the Yangtze, is the world\'s fourth longest. The Taklimakan Desert, in western Xinjiang Uygur Autonomous Region, is one of the driest spots on Earth. The area of loessic soil (fine, siltlike soil created by wind action in dry regions) in Shaanxi and Shanxi provinces is probably more extensive than in any other place. China has a great wealth of mineral and natural resources.

Superconductors A superconductor is an element or compound that will conduct electricity without resistance below a cretin temperature. The phenomenon was discovered in 1911 by Kamerlingh Onnes, who found that the resistance of mercury dropped suddenly to zero at a temperature of about 4.2°K. For the next 75 years there followed a rather steady string of announcements of new materials that become superconducting near absolute zero. A major breakthrough occurred in 1986 when Karl Alexander Müller
