Dyslexia is a learning disability, a condition that makes it difficult to learn and understand things in the same way others do. It is a very common problem and has an effect on the way our brain understands words. The most common signs of dyslexia are reading and writing problems. Estimates are that in the United States between 5 and 9% of school children have dyslexia, though estimates go as high as 50%. Some cases of Dyslexia can be more damaging, commonly caused by a tumour in the brain which can result in lower cognitive function and in many cases, death. Dyslexia tumours can appear anywhere in the brain meaning that some dyslexia is different from others, ranging from problems with letters to paralysis and often death. There are a large array of dyslexia types, the rarest being contagious dyslexia. Approximately 1 in every 1,000,000,000 (billion) person suffers from this, which is located in the lower half of the cerebellum in all cases. This is critically damaging to motor skills such as movement and speech, often leading to major paralysis if the tumour grows.
A person can have dyslexia even if they is very smart or educated. Recent studies show there are many small business owners that have dyslexia; between 35 and 50 percent of U.S. and British entrepreneurs are affected. Researchers think many dyslexic entrepreneurs are successful because they can delegate responsibilities (of writing letters) and still be good at speaking.
At the end of the 19th century, scientists did a lot of research about dyslexia and found some of the reasons that people are dyslexic. A professor who did research in the 1980s and 1990s looked at the brains of dyslexic people who had died. He found that some parts of the brain were not connected very well, and that this happened during the fourth month of pregnancy. This problem has a big effect on the left half of the brain. The newest research shows that three genes are the reason for dyslexia.
One thing that causes dyslexia is a problem with the central hearing nerve. This problem can not be found with a normal hearing test, so a special doctor has to do special tests to find it. It means that people with heavy dyslexia are sensitive to loud noise, may have problems speaking, and may not be able to concentrate. It may also cause problems with rhythm and melody of music.
Many people who have dyslexia also have other mental disorders, especially attention-deficit hyperactivity disorder (ADHD).
In order to tell if a child has dyslexia, they have to be seen by a doctor. A child can be called dyslexic if they cannot read or write well and there is no other reason for the problem. Doctors are trying to create early tests to help find out whether a child has dyslexia before they are old enough to go to school. If this happens, a child can start to be treated very early, and they may have fewer problems at school. Many well-known people have dyslexia, including: Stephen Hawking, Jamie Oliver, Whoopi Goldberg, Ozzy Osbourne, Jay Leno, John de Lancie, Keira Knightley, Susan Hampshire, Orlando Bloom, Keanu Reeves, Richard Branson, Henry Winkler, Patrick Dempsey, Albert Einstein, and Tom Cruise. These people though continue to thrive with their work.
Children with dyslexia can be helped. One way teachers help dyslexic students is to break words into different sounds. The student must learn how to write the different sounds and create words. This helps with reading and writing. Some people think that dyslexic children can read and write better if they put pieces of colored paper on top of what they are reading.
AK-47
The AK-47 is a Russian assault rifle first used in 1949. It and an updated version called the AKM were used by the Soviet Union's military (which was called the Soviet Army). It was later replaced by the AK-74.
The AK-47 was designed in 1947 by Mikhail Kalashnikov.
The AK-47 quickly became famous and spread all around the world because it was simple to fire, clean and maintain, and also because of its reliability, meaning that it can be fired for a long time without jamming. The AK-47 and its successors continue to be used by many of the world's armies. Many terrorist and insurgent groups also use the AK-47. It is a cheap, reliable, and easy-to-use weapon. The AK-47 was also available with a folding stock, the AKS-47, and a shortened version with the AKS74 folding stock, the AKMSU (used by armoured vehicle crews), although this was soon replaced by the AKS74U, which fires the 5.45 cartridge of the AK-74. There was also a light machine gun variant with a longer barrel and different shaped stock called the RPK.
The Russian military liked the AK's design so much that it was even used to design other types of weapons as well, including the Dragunov sniper rifle and the Saiga-12 semi-automatic shotgun.
The AK-47 uses gas-operated reloading. When the bullet is moved down the barrel, a little bit of the gas behind the bullet is made to go up a small tube that pushes away the bolt. The shooter does not have to reload by hand for every shot - the gun reloads by itself. When you pull the trigger, the bullet in the chamber fires. You then release and then pull the trigger again to fire another round. When used this way, it is called a semi-automatic firearm. A few AK-47's are made to be used only this way but most are fully automatic firearms.
In the pro-communist states, the AK-47 became a symbol of the Third World revolution.
They were used in the Cambodian Civil War and the Cambodian–Vietnamese War. During the 1980s, the Soviet Union became the principal arms dealer to countries embargoed by Western nations. This included Middle Eastern nations such as Iran, Libya, and Syria, which welcomed Soviet Union backing against Israel. After the end of the Soviet Union (1989/90), AK-47s were sold openly and on the black market to any group with cash, including drug cartels and dictatorial states. More recently they have been seen in the hands of Islamic groups such as Al-Qaeda, ISIL, and the Taliban in Afghanistan and Iraq, and FARC, Ejército de Liberación Nacional guerrillas in Colombia.
The proliferation of this weapon is shown by more than just numbers. The AK-47 is included in the flag of Mozambique, an acknowledgment that the country gained its independence in large part through the effective use of their AK-47s. It is also found in the coats of arms of East Timor and the revolution era Burkina Faso, as well as in the flags of Hezbollah, FARC-EP, the New People's Army in the Phillipines, TKP/TIKKO and other "Revolutionary Peoples" groups.
