Sodium
Sodium Life could not exist without compounds of sodium. These compounds hold water in body tissues, and a severe deficiency of sodium can cause death. Blood contains sodium compounds in solution. Sodium compounds are used in industry in the manufacture of chemicals and pharmaceuticals, in metallurgy, in sodium vapor lamps, and in the production of hundreds of every day products. One of the most common sodium compounds is table salt, or sodium chloride. In its pure form sodium is a silver-white,...

France's Ecconomy
France\'s Ecconomy France is one of the world\'s richest nations. Industrialization began at the end of the 18th century. Unlike England and the rest of Europe, France failed to maintain the momentum of its early industrial start and was still an agricultural nation at the end of the 19th century. Most growth has occurred since the end of World War II. France now ranks among the world\'s most economically advanced nations. A distinctive feature of the postwar French economy has been national eco...

Ural Mountains
Ural Mountains David Bennington Bennington 1 Mr. Macintosh Environmental Science CP9 HR. 5 1/6/96 The Ural Mountains are a rugged spine across Russia, running 1,300 miles from the fringe of the Arctic in the North, to the bend of the Ural River in the South. Traditionally they form a boundary between Europe and Asia. The north- south course of the Urals is relatively narrow, varying from about 20 to 90 miles in width, but it cuts across the vast latitude landscape regions of the Eurasian landmas...

Birth Of Communication
Birth Of Communication Outline I. It is important to reflect ones own national and cultural identity to understand what is different among people of different nations. History teaches us that culture always changes because of internal or external influences, even our own cultures and values change over time. Our world today is a world in which people from different nations and cultures are getting closer and closer because of economical and political reasons. Because cultures are becoming close...

Cyprus
Cyprus Cyprus, an island in the Eastern Mediterranean, at the cross-roads of three continents - Europe, Asia and Africa - has one of the oldest histories of the world, dating back 9000 years. Its strategic position, its wealth in forests and mineral deposits, as well as its skilled craftsmen, made it the prized possession of the powers of the day. Cultural influences came from all directions - all m...

Manganese Nodules
Manganese Nodules What are m n? The Cook Islands Exclusive Economic Zone (EEZ) covers 1.8 million square kilometres. In this area, the most significant mineral resource is manganese nodules that are found on the seabed (see cover drawing of a nodule cross-section). These nodules are formed by metallic elements that slowly precipitate out of the ocean water. The most abundant element is manganese. Nodules may grow at a rate of about two millimetres per million years. Deep currents flowing from th...

Modeling of Structural and Compositional Homogeniz
Modeling of Structural and Compositional Homogenization of Plutonium-1 Weight Percent Gallium Alloys The microstructure of as-cast Pu-1 wt pct Ga alloys is characterized by extensive Ga microsegregation often referred to as coring. This process results in grains that consist of Ga-rich cores (,1.6 wt pct) with Ga-poor (,0.1 wt pct) edges. Cored grains can be homogenized at moderately high (i.e., 400 C) temperatures, though the time required to achieve chemical homogeneity is not well constrai...

John Dalton
John Dalton John Dalton was born in 1766 and died in 1844. He was born and raised in Eaglefeild, near Cockermouth, in Cumberland, England.

He also accomplished several other things in his lifetime. Including discoveries and observations of comets, discoveries in the field of Metallurgy, and color blindness. Thi...

The Metallurgy of Copper Wire
The Metallurgy of Copper Wire Introduction Copper is the preferred and predominant choice in the electrical industry because of its high conductivity, both electrical and thermal. In order to obtain the required properties, unalloyed high purity copper is almost always used. This article discusses the rationale for this choice, and pays particular attention to the underlying metallurgical principles. It is intended to serve as a technical discussion of pertinent developments spanning the past se...

Consequences of Military Expenditure on the Econom
Consequences of Military Expenditure on the Economy For many years, debate has raged whether spending billions of dollars on the army, nuclear arsenal and missiles is beneficial to the economy, of developing and developed nations, as well as the international economy. Naturally, military spending peaks during times of war; which historically has coincided with periods of economic growth. Economists have argued that war spending creates jobs and encourages investment in research and development; ...
