Alnico alloys can be made magnets by strong magnetic fields. Rare-earth magnets like neodymium and samarium-cobalt are the only easily found magnets which are stronger than alnico magnets. Alnico magnets produce very strong magnetic fields at their poles (a pole is one of the two ends of a magnet) as high as 1500 gauss (0.15 tesla which is about 3000 times stronger than earth's magnetic field.
Some types of alnico magnets are isotropic (properties are same in all directions) and can be properly magnetised in all directions. Other types like alnico 5 and alnico 8 are anisotropic (properties change when direction changes) have a preferred direction (one direction would be better than other directions) for magnetisation. Anisotropic alnico alloys will make stronger magnets in their preferred direction than an isotropic alnico alloy.
Alnico magnets are the only magnets that have useful magnetism even when heated red-hot.
In 2008, the cost of Alnico magnets was about $44/kg ($20/pound).
Hermit Thrush
The hermit thrush ("Catharus guttatus") is a common bird that is found in North America. The size of one is 15 to 17 cm. It has a brown head. It is closely related to the Mexican Russet nightingale-thrush. They are mainly brown and have a reddish tail. Underneath they are white with some dark spots. They have pink legs. The hermit thrush is the state bird of Vermont.
Lord Lieutenant of Ireland
The Lord Lieutenant of Ireland (plural: Lords Lieutenant) is the name of a political office ("job"). It was the representative of the King and head of the Irish executive (government) between 1171 and 1922. The term is always pronounced as 'Lord "Lef"-tenant of Ireland'.
Other words used for this office were Judiciar in the early medieval period, and Lord Deputy as late as the 17th century. The people in this job were often also called viceroy, from the French "vice roi" or deputy king.
In the Middle Ages some Lord Lieutenants had been Irish noblemen. After that only noblemen from Great Britain worked in this job.
The King's representative had a number of different roles. He was
The Lord Lieutenant was helped to govern by the Irish Privy Council. This was a group of people chosen to be on the Council. Some inherited their seat. They usually met in the Council Chamber in Dublin Castle.
The main politicians were:
Lords Lieutenant stayed in power until the British Government/the King wanted them to leave.
Two Lords Lieutenant, Lord Hartington and the Duke of Portland, went from Dublin Castle to 10 Downing Street as Prime Minister of Great Britain, in 1756 and 1783 respectively. At other times, the post was used to move politicians that were no longer wanted in London out of the way.
By the mid-to-late 19th century the post was no longer very important. The Chief Secretary for Ireland had become more important in ruling the country than the Lord Lieutenant.
The official house of the Lord Lieutenant was the Viceregal Apartments in Dublin Castle. This was also where the Viceregal Court was based. When the Lord Lieutenant had to live in Ireland full time, this had to change. In 1781 the British government bought the former ranger's house in Phoenix Park. It was named the Viceregal Lodge. It is now known as Áras an Uachtaráin. It is the residence of the President of Ireland.
The Lords Lieutenant then only lived in the Castle during the Social Season (early January to St. Patrick's Day, 17 March).
The office of Lord Lieutenant, like the British government in Ireland, was generally unpopular.
From the early 19th century, calls were made frequently to get rid of the office. However, the office survived right down until the end of British rule in most of Ireland.
Dublin Zoo
The Dublin Zoo (), in Phoenix Park, Dublin, Ireland is the largest zoo in Ireland. It is one of Dublin's most popular attractions. It was opened in 1831.
It is over in size. It has a number of special areas like:
It was founded on 10 May 1830 and opened to the public on 1 September 1831. This makes it the third oldest zoo in the world. The animals, 46 mammals and 72 birds,< were a present from London Zoo.> It now has over 600 animals from all over the world.
In 2010, Dublin Zoo received 963,053 visitors.
How to
A how-to or a how to is an informal, often short, description of how to do a specific physical task, think to solve a specific problem, or think about a topic.
Wild type
Wild type is a term in genetics for the most common type in a natural population. It is applied to alleles of a gene, or the genotypes or phenotypes of a species.
The term is used in genetics to contrast normal alleles with mutant alleles.
With "Drosophila melanogaster", wild type usually means the standard version of the famous laboratory population used in the T.H. Morgan laboratory, and since used around the world. This was, of course, only a sample of the natural populations.
CMUNE
Cmune is a software development company. It is the maker of UberStrike, a popular web-based video game. Cmune was started in 2007 by Shaun Lelacheur Sales and Ludovic Bodin.
UberStrike was originally developed under the name Paradise Paintball. It is a free, multiplayer first-person shooter browser game. There are over 10 million registered players. As of November 2012, it was still the largest FPS inside Facebook.
Tábor
Tábor is a city in the Czech Republic. It is in the South Bohemian Region. At the 2007 census, 35,859 people lived there. The city was started in 1420. The current mayor is Hana Randová. The city is named after Mount Tabor.
Yamaguchi, Yamaguchi
Yamaguchi is a city in southern Japan. It is the capital of Yamaguchi Prefecture. The city had a population of 198,971 people in 2010. Yamaguchi was made when 40 towns were merged together on April 1, 1889.
Random mating
Random mating is a term in population genetics. It describes an ideal situation in which all individuals on one sex are equally potential partners of all members of the opposite sex. The technical term for it is panmixia.
Random mating is one of the requirements for the Hardy–Weinberg law to hold. This is the foundation equation of population genetics.
There are a number of types of non-random mating, such as mate choice (selection by females from a small group of males), mating type (in microorganisms like "Paramecium"), selfing in some flowering plants, and in general, inbreeding. Mechanical or geographical differences within a species will often prevent a whole species being panmictic.
The opposite of random mating is "assortative mating".
Ernst-Happel-Stadion
The Ernst-Happel-Stadion is a football stadium in Vienna, Austria. The Ernst Happel Stadium is the largest football stadium in Austria. It is the home of the Austrian national football team. Club football matches are limited to the Austrian cup final and international competitions with one of Vienna's top clubs, FK Austria Wien and SK Rapid Wien, as their homegrounds are too small for UEFA Champions League and UEFA Cup matches. Local derbies between FK Austria and SK Rapid have also been played in the stadium. In 2014, it became the official homeground of SK Rapid Wien because their stadium was being rebuilt.
The stadium was built between 1929 and 1931. It was used and opend for the second Workers' Olympiad 1931. The capacity of the stadium was approximately 60,000 people. The first match in the new stadium was a match between a selection from workers sportclubs from Lower Austria and Vienna. (2:3).
During the occupation of Austria by Nazi Germany it was used as barracks and also as collecting point for Viennese Jews. In 2003 a private plaque was created in the VIP area to remind on this incidents. In 1944 the stadium was bombed and heavily demaged.
