Discuss the effect that political and economic factors had on the composition of Handel’s Judas Maccabaeus. ‘Judas Maccabaeus’ is an oratorio composed by George Friderick Handel and was written to be first performed in 1747. The piece was written in honor of the duke of Cumberland to acknowledge his success in the battle of Culloden during the Jacobite rebellion. The political links with the work had a clear influence on the final outcome of the piece‚ and this is shown through its story and

Hossain Descriptive Essay July 2‚ 2013 The Ocean The ocean‚ from the Pacific to the Atlantic and the Indian to the Artic‚ is a vast and enchanting part of our world. The oceans of this world cover more than sixty six percent and that number is steadily rising. There are so many facets of the ocean that are yet to be discovered‚ but as someone who lives fifteen minutes away from a beach‚ it is hard not to be intoxicated by the allure that the ocean draws. Oceans have their own smell‚ feel‚ taste and sound

Abstract The purpose of this lab was to study the composition of hydrates. Hydrates are ionic compounds that are chemical compositions made of water and salt. A main objective was to remove water from the hydrate by heating‚ and determine the amount of water that was in the hydrate. After doing this‚ one had to predict the empirical formula for hydrated copper sulfate. In doing this lab‚ one was able to see the gradual change in the composition of a hydrate into an anhydrous salt. The lab was

1. Crust: The Earth’s surface is composed mostly of water‚ basalt and granite. Oceans cover about 70% of Earth’s surface. The Earth’s thin‚ rocky crust is composed of silicon‚ aluminum‚ calcium‚ sodium and potassium. The crust is divided into continental plates which drift slowly (only a few centimeters each year) atop the less rigid mantle. The crust is thinner under the oceans; this is where new crust is formed. Continental crust is about 25-90 km thick. 2. Mantle: Under the crust is the rocky

THE EARTH At the beginning our planet is no more than a case of fire and cloud with glutenated dust particles similar to so many similar cloisters in the universe. This was the miracle where our life exists in this universe. Today life our life is just a link or chain of so many numerable living beings that was succeeded one another honours over nearly 4 billion years and even today new volcanoes continue to sculpt our landscapes it appears like molten rocks from the depths‚ solidifying‚ cracking

The Ocean Floor No one has ever walked the sea floor and few have even seen it. This is because of the extreme conditions found there. It is dark‚ and the temperature is close to freezing. A person standing on the sea floor would be under tremendous pressure from the overlaying water. The pressure is hundreds of times greater than the atmospheric pressure. Such a force would crush the human body. Using research submersibles which are specially designed to with stand the pressure of the water‚ scientists

EARTH SURFACE REALMS 2And3 We can look at Earth’s surficial "layers" as being comprised of several major realms or "geospheres": the atmosphere‚ lithosphere‚ hydrosphere‚ biosphere and pedosphere. The reference to "sphere" applies because Earth is spherical‚ and hence layers around it form somewhat spherical shells at the outermost edges of the solid planet. The atmosphere‚ biosphere and lithosphere more completely encircle Earth‚ while the hydrosphere and pedosphere tend to be more discontinuous
