It has long been the economic centre of northern Nigeria, and a centre for the sale of groundnuts. Kano is known for the Bayero University and a railway station with trains to Lagos, moving through Kaduna, while Kano International Airport can be found nearby. Kano has long been a centre for Nigeria's Islamic culture; one of the country's finest mosques lies in the city.
It is also the site where the Kano river project was developed. This is a large irrigation scheme.
The city of Kano was founded around A.D. 1000 as an Hausa city of its own. Kano remained a big emirate, or Muslim kingdom, until the making of the country, Nigeria, in 1903. Kano became known for its trade in gold, leather, ivory, salt and slaves within the area. This perhaps is the reason for the city's wealth and power in the 14th century, when Islam gained a growing following. By the 15th century, the first Central Mosque had been built in the city.
Battle of Bosworth Field
The Battle of Bosworth or Bosworth Field was an important battle during the Wars of the Roses in 15th century England. It was fought on 22 August 1485 between the Yorkist King Richard III, the last of the Plantagenet dynasty, and the Lancastrian Henry Tudor, 2nd Earl of Richmond, who wanted to become king. It ended in the defeat and death of Richard and the beginning of the Tudor dynasty. Historically, the battle is thought to have marked the end of the Wars of the Roses, although smaller battles were fought in the years that followed as Yorkists unsuccessfully tried to become king again.
The place of the battle is not precisely known. Memorials have been built in some of the possible locations.
The Battle of Bosworth is an important part of William Shakespeare's play "Richard III". The action of the play ends with this battle.
Escherichia coli
Escherichia coli or E. coli is a bacterium that lives in the intestines of people and other warm-blooded animals. Scientists have studied "E. coli" a lot, and know more about how "E. coli" cells work than any other organism. "E. coli" is usually not harmful. In fact, the only known harmful strain is O157. E.coli is a prokaryotic organism.
"E. coli" normally grow in soil and in the large intestines of many mammals, including humans. Most strains of "E. coli" do not cause disease, but instead help animals get vitamins and digest food. Some strains of "E. coli" cause sickness in people. "E. coli" are not usually in food or water. When food has not been prepared with clean equipment, "E. coli" can grow in the food. When "E. coli" are found in water, this may mean that the water has touched sewage.
It is named after Theodor Escherich, who discovered it in 1885. It was officially named after him in 1919.
The following signs and symptoms of an "E. coli" infection normally happen within three days; however, some people may carry the infection and show no signs at all.
The best treatment for "E. coli" is plenty of fluids to avoid dehydration.
Borg (Star Trek)
The Borg are a fictional race of cyborgs in the Star Trek universe. The Borg use nanoprobes to assimilate others, like humans or vulcans, into their group consciousness. The Borg's group consciousness is led by the Borg queen, who's role is similar to that of a queen bee in a bee hive.
House of Plantagenet
The House of Plantagenet ruled England in some form or another from the reign of Henry II, beginning in 1154, until the House of Tudor came to power when Richard III fell at the Battle of Bosworth Field in 1485.
It goes back to the Angevin counts (from 1360, dukes) of the western French province of Anjou. Three dynasties belong to it: Angevins, House of Lancaster (Lancastrians) and House of York (Yorkists). Lancastrians and Yorkists fought against each other the Wars of the Roses to get the crown for their dynasty alone.
Angevin
Angevin is the name of the residents of Anjou, a former province of the Kingdom of France, as well as to the residents of Angers. It is also used for three different medieval dynasties which go back to counts (from 1360, dukes) of the western French province of Anjou (of which "angevin" is the adjectival form), but later came to rule far greater areas including England, Ireland, Hungary, Croatia, Poland, "Kingdom of Naples and Sicily", and Kingdom of Jerusalem ("see Angevin Empire").
The first of these Angevin dynasties, the House of Plantagenet, ruled England in some form or another from the reign of Henry II, beginning in 1154, until the House of Tudor came to power when Richard III fell at the Battle of Bosworth Field in 1485.
Count
A count is a nobleman in most of European countries, equivalent in rank to a British earl, whose wife is also still a "countess" (for lack of an Anglo-Saxon term). The word "count" comes from French "comte" which in turn comes from the Latin "comitas", "companion" (of the emperor). In feudalism the territory ruled by a count was a county.
A woman having this title or the wife of a count is called countess.
Budgerigar
The budgerigar (nicknamed budgie) is a small parrot. It belongs to the family of old-world parrots and parakeets (Psittaculidae). Budgerigars are often called "parakeets", especially in American English. The term "Parakeet" refers to many types of small parrots with long flat tails. The budgerigar is found in the drier parts of Australia. It has lived there for over 5 million years. It is commonly kept as a pet. Budgies are intelligent birds and can be taught to mimic human speech.
Endocarditis
Endocarditis is an inflammation of the inner layer of the heart. Endocarditis most often affects the heart valves. The heart valves are a part of the human body that does not get blood. This is odd because they are a part of the heart itself. Because of this, if one of the valves gets infected with bacteria or protozoa, the body can not defend itself against those bacteria. This can cause the valve to not work the way it should.
Tetracycline
Tetracycline is a family of antibiotics discovered as natural products in 1945. It is a broad-spectrum antibiotic because it works against a range of bacteria.
Tetracyclines was first prescribed in 1948. It is produced naturally by the "Streptomyces" genus of Actinobacteria. It is a protein synthesis inhibitor.
In 1950, Harvard University professor Robert Burns Woodward worked out the chemical structure of the related oxytetracycline (Terramycin). The patent protection for its production was also first issued in 1950.
Tetracycline is an antibiotic used to treat a number of bacterial infections. It is commonly used to treat acne and rosacea. Historically it was important in reducing the number of deaths from cholera. It is on the World Health Organization's List of Essential Medicines.
Hemoglobin
Hemoglobin (or haemoglobin) is a protein in red blood cells which contains iron. It is used to transport oxygen around the human body. Hemoglobin is found in the red blood cells of all vertebrates apart from white-blooded fish. It also occurs in some invertebrates. Some other invertebrates use other chemicals such as hemocyanin
Hemoglobin is involved in the transport of other gases. It carries some of the body's respiratory carbon dioxide (about 20-25% of the total).
Red blood cells get their colour from hemoglobin, which is red. There are millions of hemoglobin molecules in each red blood cell and millions of red blood cells in the human body. When hemoglobin has oxygen attached, it is called oxyhemoglobin.
The most common type of hemoglobin in mammals contains four such subunits. Each subunit of hemoglobin is a globular protein (globin) with a heme group inside it. Each heme group has one iron atom. This binds one oxygen molecule. So the complete hemoglobin molecule has four globin chains, four heme molecules, and four iron atoms. When hemoglobin is in the lungs, it picks up oxygen in its hemes, and carries it to the rest of the body.
