INTRODUCITION the construction industry has many advantages as well as many disadvantage. For one side‚ this industry provides new ways to improve our lifestyle and welfare‚ it help us to survive climate‚ and give us plenty of facilities to all the social need that we have. But the bad part of this industry is that in order to satisfy all our needs‚ the environment results damaged‚ due the exploitation of the natural resources needed to produce construction materials‚ and the devastation of natural

Introduction of Ceramics What is Ceramics? A ceramic is an inorganic‚ non-metallic solid prepared by the action of heat and subsequent cooling. Ceramic materials may have a crystalline or partly crystalline structure‚ or may be amorphous (e.g.‚ a glass). Because most common ceramics are crystalline‚ the definition of ceramic is often restricted to inorganic crystalline materials‚ as opposed to the non-crystalline glasses. The word ceramic comes from the Greek word "κεραμικός" (keramikos)‚

Al Gore stated that the new president and the new Congress should offer large-scale investments in incentives for the construction of concentrates solar thermal plants in places that could produce large amounts of electricity. He says we should then begin the planning and construction of a unified national smart grid for the transport of

Biology Lab Report BY: Michael Ryan Pranata 11C | Background: As heat is a form of thermal energy‚ they tend to have the behavior of reaching a thermal equilibrium. This means that when two bodies of different temperatures come in contact with each other‚ the hotter ones will transfer heat particles to the body with a colder temperature‚ with an aim to reach this “thermal equilibrium”‚ whatever the temperature may be. The larger the surface area‚ means there can be more “paths” from the
