Several portions of the hotel required complex engineering noteworthy acts to accomplish.

The hotel stands on an artificial Island. The builders dug 230, party meter long concrete piles into the sand to save the foundation.

A layer of large rocks and concrete is created like bee wax structure to secure the foundation. It took three years to drive its foundation secure and safe. And almost took three years to construct the building itself.

Burj Al Arab contains 70,000 m³ of concrete and 9000 tons of steel. Its very graceful luxury Hotel of the Dubai.

Burj Al Khalifa

Burj khalifa know as Burj Dubai as the tallest monument in the world. Its 2,723 ft (329.84m) highest tower not only in United Arab Emirates but also in the world.Burj Dubai’s construction began on September 21, 2004 and completed on October 1,2009, But the building on 4 January 2010. The tower’s architecture was down by Skid-more, Merrill and Owing of Chicago and Adrian Smith was chief architect while bill baker was chief structural engineer.

Samsung C&T of South Korea was the primary contractor of the tower. In US dollars total cost of the project was about 1.5 billion and for the whale downtown Dubai development 20 billion US dollars.

Chairman of the project’s developer, Mohamed Ali Alabbar said office space pricing at Burj Dubai reached nearly 4000 US dollars per square ft. The residence pricing is 3500 square feet. The project’s completion surrounded with financial crisis of 2007, 2010.

 Burj Dubai got involved in difficulties and debt from its huge ambitions and the Government was forced to find sponsors from Abu Dhabi. But after, in a surprise move at its inauguration ceremony, the Burj has renamed Burj Khalifa, in honor to the President Khalifa bin Zayad for his support.

The Palm Islands

The Palm Islands are an artificial group of Islands in Dubai. United Arab Emirates on which major commercial and dwelling Place infrastructure will be built. They are being build by Nakheal Properties, a property evolutioner in the UAE, who employed Belgian and Dutch marine and dredging contractor Jan De Nul and Van Oord, some of the world's most devoted persons in land reclamption. The Islands are the Palm Jebel Ali , The Palm Deria And The Palm Jumeirah. Each establishment will be in the shape of Palm Tree, topped with a increasing moon and will have numerous residential, entertainment and leisure centers.

The Palm Islands are situated off the Sea shore of the UAE in the Persian Gulf and will plus 520 kilometers of beaches to the city of Dubai

The first two Islands will include nearly 100 million cubic meters of rock and sand. Palm Deria will be made of approximately one billion cubic meters of sand and rock. Excavation for building stone will be in UAE.

Between the three Islands there will be more than 100 Luxuries Hotels, Special Residential Beach Side Villas and Apartments Restaurant, Water Theme Parks, Marinas and Best Serving Health Spas.

The construction of the Palm Jumeirah started in June 2001. Briefly after the Palm Jebel Ali was proclaimed and reclamation work began. The Palm Deira which is Schemed for accomplishment of surface area of 46.35 square kilometers, was proclaimed for development in October 2004

Aurora

For thousands of years Aurora has been one of the most conspicuous mysteries to be solved.
In ancient Romans, Aurora is known as the the goddess of the dawn.It is thought that aurora is
burning of volcanoes,an extensive prairie or a forest fire in the interior of the earth.
In North America it is called the dance of spirits.
Aurora is the natural colors lights which can be seen at poles. Mostly aurora occour at poles. In north pole it is called Aurora borailis and in south pole it is called aurora australis.

As you know that earth behaves like a magnet.There is a magnetic field around the earth. Earth magnetic activity is due to the molten iron present in the core of earth. Magnetic field of earth is extend from earth's core to space.The field lines go into and out  of the Earth . magnetic field of the earth prevents earth from solar radiations. These solar radiations are very harmful for life.

These solar radiations is of course also essential for life on earth. solar heating drives weather system and ocean currents and for photosynthesis. As the result of photosynthesis oxygen gas is released into the atmosphere. Oxygen and nitrogen are mainly present in the atmosphere as well as in ionosphere.the molecules of these gases are present in form of atoms because it absorbs high energy photons from the sun. .Ionization depends primarily on the Sun and its activity.The amount of ionization in the ionosphere varies greatly with the amount of radiation received from the Sun.
Aurora is caused by high energy particles from the solar wind which are  trapped in earth's magnetic field.As these particles enters in magnetic field they come down into the atmosphere near the north and south magnetic poles where magnetic lines disappear.
As these high energy particles stokes with oxygen and nitrogen molecules in ionosphere, this excited the molecules and they emit light when they when they come to their ground state.The emission of energy are of different color because of different gases.

Oxygen        green or brownish red

Nitrogen      blue or red

The extent of color shown also depend upon the amount of radiations absorb.
