Anuska








Anushka Shetty was born on 7th November 1980 in Mangalore, Karnataka. She is known to her close friends as Sweety. She is a graduate in computer applications from Mount Carmel College and has also trained in yoga under Bharat Thakur and now takes yoga classes. Anushka Shetty began her acting career in Telugu cinema as Sasha in Super with Sonu Sood and Nagarjuna. She delivered more hits with Vikramarkudu , Rendu and Astram.Lakshyam did well while Okka Magadu and Baladoor failed to do well. She made up for it with Souryam and Chintakayala Ravi. Her performance as Arundhati and Jejamma in the supernatural flick Arundhati earned her good reviews. Billa in which she acted with Prabhas as Maya became a blockbuster.

Iron metal: the part of our life

Iron (US pronunciation: with two syllables, and UK pronunciation: with one) is a chemical element with the symbol Fe (Latin: ferrum) and atomic number. It is a metal in the first transition series. Like other group 8 elements, it exists in a wide range of oxidation states. Iron and iron alloys (steels) are by far the most common metals and the most common ferromagnetic materials in everyday use. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in air.Iron is the most common element in the earth as a whole, and the fourth most common in the Earth's crust. It is produced as a result of stellar fusion in high-mass stars, and it is the heaviest stable element produced by stellar fusion because the fusion of iron is the last nuclear fusion reaction that is exothermic. Iron is the most widely used metal, and iron compounds, which include ferrous and ferric compounds, have several uses as well.Iron has been used since ancient times, though not as early as bronze or the other copper related alloys. Iron is ubiquitous in modern life; it is used primarily for its structural strength. Pure iron is soft (softer than aluminium), but the material is significantly strengthened by addition of minute amounts of impurities, such as carbon. Alloying iron with appropriate small amounts (up to a few per cent) of other metals and carbon produces steel, which can be 1,000 times harder than pure iron. Iron is smelted in a blast furnace, where ore is reduced by coke to metallic iron.Elemental iron is reactive; it oxidizes in air to give iron oxides, also known as rust. The rusting of iron and iron alloys is undesirable, and has a major economic impact. Unlike many other metals which form passivating oxide layers, iron oxides occupy more volume than iron itself. Thus, iron oxides flake off and expose fresh surfaces for corrosion. Iron oxide mixed with aluminium powder can be ignited to create a thermite reaction, used in welding and purifying ores.Iron exists from oxidation state , although are the most common. It forms binary compounds with the halogens and the chalcogens. Among its organometallic compounds, ferrocene was the first sandwich compound discovered. Iron plays an important role in biology, forming complexes with dioxygen as hemoglobin and myoglobin; these two compounds are common oxygen transport proteins in vertebrate
