Inverness vs Cobalt

Informations

Inverness ( (listen); from the Scottish Gaelic: Inbhir Nis [iɲɪɾʲˈniʃ], meaning "Mouth of the River Ness"; Scots: Innerness) is a city in the Scottish Highlands. It is the administrative centre for The Highland Council and is regarded as the capital of the Highlands. Historically it served as the county town of the county of Inverness-shire. Inverness lies near two important battle sites: the 11th-century battle of Blàr nam Fèinne against Norway which took place on the Aird, and the 18th century Battle of Culloden which took place on Culloden Moor. It is the northernmost city in the United Kingdom and lies within the Great Glen (Gleann Mòr) at its northeastern extremity where the River Ness enters the Moray Firth. At the latest, a settlement was established by the 6th century with the first royal charter being granted by Dabíd mac Maíl Choluim (King David I) in the 12th century. The Gaelic king Mac Bethad Mac Findláich (MacBeth) whose 11th-century killing of King Duncan was immortalised in Shakespeare's largely fictionalised play Macbeth, held a castle within the city where he ruled as Mormaer of Moray and Ross.The population of Inverness grew from 40,969 in 2001 to 46,969 in 2012, according to World Population Review. The Greater Inverness area, including Culloden and Westhill, had a population of 56,969 in 2012.

In 2018, it had a population of 69,696. Inverness is one of Europe's fastest growing cities, with a quarter of the Highland population living in or around it, and is ranked fifth out of 189 British cities for its quality of life, the highest of any Scottish city. In the recent past, Inverness has experienced rapid economic growth: between 1998 and 2008, Inverness and the rest of the central Highlands showed the largest growth of average economic productivity per person in Scotland and the second greatest growth in the United Kingdom as a whole, with an increase of 86%. Inverness is twinned with one German city, Augsburg, and two French towns, La Baule and Saint-Valery-en-Caux.Inverness College is the main campus for the University of the Highlands and Islands. With around 8,420 students, Inverness College hosts around a quarter of all the University of the Highlands and Islands' students, and 30% of those studying to degree level.In 2014, a survey by a property website described Inverness as the happiest place in Scotland and the second happiest in the UK. Inverness was again found to be the happiest place in Scotland by a new study conducted in 2015.

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was later thought to be due to the known metal bismuth. Miners had long used the name kobold ore (German for goblin ore) for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the kobold. Today, some cobalt is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). The element is, however, more usually produced as a by-product of copper and nickel mining.

The copper belt in the Democratic Republic of the Congo (DRC) and Zambia yields most of the global cobalt production. World production in 2016 was 116,000 metric tons (114,000 long tons; 128,000 short tons) (according to Natural Resources Canada), and the DRC alone accounted for more than 50%.Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys. The compounds cobalt silicate and cobalt(II) aluminate (CoAl2O4, cobalt blue) give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. Cobalt occurs naturally as only one stable isotope, cobalt-59. Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high-energy gamma rays. Cobalt is the active center of a group of coenzymes called cobalamins. Vitamin B12, the best-known example of the type, is an essential vitamin for all animals. Cobalt in inorganic form is also a micronutrient for bacteria, algae, and fungi.
