extraordinary example was the Hammurabi’s code which was discovered by Egyptologist‚ Gustave Jequier and Jaques de Morgan in the year 1902 CE‚ during the famous Susa expedition in modern day Iran. During the expedition‚ Gustave Jequier unearthed a massive basalt stone stele covered in an ancient dialect of Mesopotamian cuneiform. To decipher the long dead language‚ Jaques commissioned cuneiform expert‚ Jean-Vincent Scheil‚ to decipher the text. In the year 1902 CE‚ Scheil published his remarkable findings

obelisk that was set up between 100-300 A.D in Axum‚ the city of the princess of Sheba. This pillar was a symbol of their Christianity‚ Patriotism‚ independence and freedom for the Ethiopians. The Ethiopian emperors had to kneel down before these basalt pillars at their coronations in order to receive the power for their absolute leadership. It signifies anteriority‚ primacy and exemplary leadership. The obelisk elegantly captures the ancestors’ sense of the sacrifice for freedom and independence

it to the surface and it cools inside the earth’s crust. Igneous rocks are formed from cooled magma. If magma cools below the earth’s surface it forms intrusive igneous rocks (gabbro); if it cools above the surface it forms extrusive igneous rocks (basalt) (Armstrong n.d.). As soon as rocks are exposed at the earth’s surface‚ the eroding or weathering process begins. Physical and chemical reactions caused by contact with air‚ water‚ and organic entities cause the rocks to break down. Erosion occurs

namely at Merapi. Here the climate is tropical meaning that with the extra fertile soils they can grow three crops a year‚ such as fruit and rice. The volcano rarely erupts violently; there is a constant stream of lava pouring from the top‚ high in basalt meaning it is viscous‚ thus meaning that the crater never gets plugged. This is the calculated risk that people take in order to live productive farming lives on the sides of volcanoes. The other main factor that is the cause for people living so

response to the collision of sections of Earth’s crust. Still others formed as a result of many lava flows that spread out over hundreds of thousands of square miles‚ building up the land surface. These latter plateaus are known as lava or basalt plateaus (basalt is the dark‚ dense volcanic rock that forms these particular lava flows). Some plateaus can form simply when the side of a land region is weathered away through erosion (the gradual wearing away of Earth surface features through the action

The device adopts the most advanced international crushing technology and manufacturing level‚ which is the first choice for crushing hardness and strong abrasive materials. Highway‚ railway‚ airport pavement and other projects all give priority to basalt and other hard rocks‚ the specifications are around 3-7 cm‚ and broken harder materials‚ the hongxing jaw crusher has low yield and also easy to wear.

ACI STRUCTURAL JOURNAL Title no. 106-S64 TECHNICAL PAPER A Practical Equation for Elastic Modulus of Concrete by Takafumi Noguchi‚ Fuminori Tomosawa‚ Kamran M. Nemati‚ Bernardino M. Chiaia‚ and Alessandro P. Fantilli Many empirical equations for predicting the modulus of elasticity as a function of compressive strength can be found in the current literature. They are obtained from experiments performed on a restricted number of concrete specimens subjected to uniaxial compression. Thus‚
