James Clerk Maxwell

**James Clerk Maxwell** (born 13 June 1831 in Edinburgh – died 5 November 1879) was a British mathematician, physicist and discoverer of Maxwell's equations.
## Early life
Maxwell grew up in a rich religious family. In 1845, when he was only 14, he wrote a paper describing a way of drawing mathematical curves with a piece of string. In 1847 he started studying mathematics at the University of Edinburgh. In 1850 Maxwell changed to Peterhouse and then Trinity College at the University of Cambridge. He won prizes from the university for his work and was given his degree in 1854. From 1855 to 1872 he did research on colour blindness.
## Works
In 1856 Maxwell was made a professor of 'Natural Philosophy' (which is what science was called then) at Marischal College, Aberdeen. He worked there until the two colleges in Aberdeen joined together in 1860 and he lost his job. He then became a professor at King's College London. In 1861 he was elected to the Royal Society.

In 1871, he became the first Cavendish Professor of Physics at Cambridge. He studied many things, but is known best for his mathematical work on electromagnetism and on the behaviour of gases. He used the experiments of Michael Faraday  to see how magnetism and electricity were connected.  This helped him to make his equations that allowed scientists to understand light and radio waves. 

He lived at Glenlair House, his family estate near the village of Parton, Castle Douglas in Kirkcudbrightshire. Maxwell died in 1879 from cancer, and is buried in the graveyard at Parton Church.

Adriano Emperado

**Adriano Emperado** (June 16, 1926 - April 4, 2009) is a Filipino-Hawaiian martial artist. He is one of five martial artists who developed a system of self-defense called Kajukenbo.

## Childhood 
As a young man in Honolulu, Hawaii, Emperado began his early training in the Filipino art of Escrima. That had a huge impact on his development of Kajukenbo. Emperado later became interested in Kenpo Karate. After years of training, he earned a fifth-degree black belt under the direction of William K.S Chow.

## Later life 
The first school of Kajukenbo was directed by Adriano Emperado and his brother, Joe Emperado. In 1959, Emperado began combining Wushu into Kajukenbo. Adriano Emperado's life has been about teaching the martial arts. *Black Belt Magazine* named him its Instructor of the Year 1991.

Jelly

Jell-O]]
:*This article is for the dessert, Jelly. See **jam** for the condiment.*
**Jelly** or **Gelatin desert** is a dessert item. It comes in different taste choices, or flavors, depending on what fruit or artificial flavor has been added. Jelly is a cold and solid food that is normally made from hot water and powder. The powder is made from gelatin and various additives.
 jelly]]

Jelly can be added to foods like a peanut butter and jelly sandwich.

## Naming and Spelling
Depending on where you live, gelatin may be called different things. In the United States and Canada, jelly is often called 'Jell-O'.  Jell-O is a brand of gelatin that has become a generic, or typical, name for gelatin desert.  In Commonwealth Nations like the United Kingdom and New Zealand, almost all gelatin is called jelly. Also, it is spelled gelatine.

## 'Jell-O Shots'
Sometimes, alcohol is added to jelly. You can make jello shots with almost any type of alcohol. Jello shots can be served in small glasses and can be any color depending on the other ingredients put into the Jell-O shot. The jello shot is also known as the poison rainbow.
Arnold Sommerfeld

**Arnold Johannes Wilhelm Sommerfeld** (December 5, 1868 in Königsberg, East Prussia &ndash; April 26, 1951 in Munich) was a German mathematician and theoretical physicist.
## Education
Sommerfeld was the son of a practical physician. After finishing school in 1886, he started studying mathematics at the University of Königsberg. In 1891 he wrote his doctorate thesis about arbitrary functions in mathematical physics. Afterwards he had to serve in the army.

Then he went to Göttingen. He became assistant at the institute for mineralogy, but was still interested in mathematical physics.
## Works
In 1894 he became the assistant of Felix Klein. The year after he wrote his habilitation about the mathematical theory of optical diffraction and became docent for mathematics in Göttingen.

In 1897 Sommerfeld married. In the same year he became ordinary professor for mathematics at the mining college of Clausthal. Three years later he got a professorship at the Technical University of Aachen.

In 1906 he became professor for theoretical physics in Munich, were he stood for his lifetime. While he was professor in Munich, he travelled twice around the world - in 1922/23 he was guest professor in Wisconsin and travelled afterwards through India, China and Japan, in 1928/29 he made a journey through the US as a university teacher.

He started taking out a pension in 1935, but he still worked until 1940. There was a lot of trouble choosing the person who should follow him. Sommerfeld wanted to have Werner Heisenberg to follow him, but in the time of the Nazi regime the job could only go to a person who taught the so-called German Physics, which included a kind of mysticism. Sommerfeld tried to prevent that.

Sommerfeld died in 1951 in a traffic accident.

Depleted uranium

**Depleted uranium** is what is left over after uranium is enriched. Enriched uranium has enough uranium-235 to be used in nuclear reactors or nuclear weapons. Depleted uranium is made up mostly of the isotope uranium-238. Uranium-238 is mildly radioactive. Uranium is very dense, or heavy for its size. Because of this, depleted uranium is used in armor piercing bullets and heavy machine guns. Its high density allows weapons to put more energy into a fired bullet which causes more damage to its targets. Bullets made from it will burn when they hit something hard, and their smoke is dangerous to breathe. 

Depleted uranium has long been used in nuclear reactors to make plutonium for producing nuclear energy. In 2010 a new kind of "traveling wave reactor" was proposed to use it more directly.

Commuting

, Yamanote Line]]
**Commuting** is the act of travelling from home to a workplace every day. A **commuter** is a person who **commutes**. This was uncommon until the 19th century, when the word was invented for people who used public transport daily. For many commuters, home is a suburb and work is in the inner city; but the reverse is sometimes the case and is called a reverse commute. Commuters may use other transport, such as cars or bicycles.

Anne Redpath

**Anne Redpath** (1895 – 1965) was a Scottish artist. She was born in Galashiels, Scotland.

She was the daughter of a tweed designer. Her father's work affected her use of colour and texture in her paintings. "I do with a spot of red or yellow in a harmony of grey, what my father did in his tweed", she said. She went to France during 1920 – 1933.

Magneto-optical drive

A **Magneto-optical drive** is a disk drive for computers. It can read and write data to magneto-optical disks. The technology was made at the end of the 1980s. Both 5.25" and 3.5" media exist. The disks look like CD-ROMs, but they are protected with a plastic cover. The MiniDisc is a Magneto-optical disk. The other disks look similar but have a bigger physical size. 

## How it works 
The operating system sees (and uses) the disk like a normal hard-drive. 3.5" disks can hold between 128 megabytes (MB) and 2.3 gigabytes (GB) of data. 5.25" disks hold between 650 MB and 16.7 GB.

## Resistance 
All disks have a physical write protection switch (like 3.5" floppy disks). They are pretty resistant to data change, can support temperatures up to about 100&nbsp;°C, and do not care much about light. 

DVD-RAM disks are very similar in appearance, they are optical though.

United States presidential line of succession

The **United States presidential line of succession** is the order in which government officials replace the president of the United States, if the president leaves office before an elected successor is inaugurated. If the president dies, resigns or is removed from the office, the vice president becomes president for the rest of the term. If the vice president is unable to serve, the Speaker of the House acts as president.

## Previous lines 
The United States Constitution says that the vice president of the United States is the person who will replace the president if the president is not able to continue. In 1868, during the impeachment trial of President Andrew Johnson, Benjamin Wade was the leader of the Senate, who nearly became president, as Johnson was found not guilty by one vote. Johnson had previously served as the vice president for Abraham Lincoln, and became president after Lincoln’s assassination. As a result, there was no vice president during Johnson’s presidency. 

In 1886, after the death of Vice President Thomas A. Hendricks, Congress passed a law that took out the leaders of the Senate and House of Representatives from the line of succession. The new person behind the vice president in line was Secretary of State, followed by other Cabinet members.  The leaders of the Senate and House were restored to the line of succession by the Presidential Succession Act of 1947.

## Present line of succession 
Below is the line of succession for the president of the United States under Donald Trump:

James Boswell

**James Boswell** (29 October 1740 (N.S.) – 19 May 1795) was a Scottish lawyer and author. He is best known for having written the Life of Johnson, a biography of his close friend Samuel Johnson, published in 1791. In the 1920s and 1930s, a large number of his personal papers and journals were discovered. They have since then been published by Yale University.

Bottle cap

**Bottle caps** are used to seal the opening of bottles. For glass bottles, these are usually small, specially adapted pieces of metal. With plastic bottles, plastic caps are used instead. 

The original bottle cap was called **Crown cork**. It is pressed onto the bottle, and can be removed, using a bottle opener.

In recent years bottle caps with screw on mounts are used that way, a bottle opener is no longer required. Caps for plastic bottles are often made of a different type of plastic from the bottle.

A cork is another type of closure for the top of a bottle.

Quality

**Quality** is how good something is. If the quality of a product is high then that means that it is fit for its . If the quality of an item is low that means that the product may break easily or not work properly. When people say something is a quality product that means that the product is of good quality. Usually higher-quality products cost more money, because the materials used to make them are better, or the way they were made was more . In other words, things that are low quality are .

Quality is understood differently by different people, depending on what they consider quality to be. Generally, though, it is how well a product is suited to the purpose it was made for.

Gargoyle

A **gargoyle** is a grotesque statue that is attached to a building. It is carved out of stone, usually granite. It is used to get water away from the building when it rains. Gargoyles are often made to look like animals or people. The collected water comes out of their mouths. Most gargoyles were made a long time ago. People used to believe that they scared away evil spirits. Many cathedrals have  many gargoyles.

New buildings use rain gutters instead of gargoyles to move water. There are not many gargoyles in America.

Gargoyles are often confused with grotesques. They are similar, but only gargoyles get rid of rainwater through their mouths.

**Abuja**  ()  is a city in Nigeria. It is the national capital of Nigeria. Around 2.5 million people live there. Abuja is in the middle of the country, in the center of the Federal Capital Territory, Nigeria.  It replaced Lagos, the country's most populous city but very small in size, as the capital on 12 December 1991.

Abuja is a planned city, which means that architects designed it specifically to be Nigeria's capital city. Construction of the first parts of the city was finished in the late 1980s.

Irony

used for sheep or goats. The bell was found in 1988 in a field near Tuqu' (Tekoa) in the Judean hills, the West Bank. The bell's body is made of aluminum, probably a broken kitchen utensil, while the clapper is a brass cartridge case. The combination of a peaceful, pastoral use and a militant detail gives this item an ironic character, symbolizing the tragic daily reality of the Middle East conflict.]] 

**Irony** is a term for a figure of speech. Irony is when something happens that is opposite from what is expected. It can often be funny, but it is also used in tragedies. There are many types of irony, including those listed below:
**Dramatic irony*, when the audience knows something is going to happen on stage that the characters on stage do not.
**Socratic irony*, when someone (usually a teacher) pretends to be stupid in order to show how stupid his pupils are (while at the same time the reader or audience understand the situation).
**Cosmic irony*, when something that everyone thinks will happen actually happens very differently.
**Situational irony* e.g. Mr. Smith gets a parking ticket. This is ironic because Mr. Smith is a traffic warden.
**Verbal irony* is an absence of expression and intention. Sarcasm may sometimes involve verbal irony.
**Irony of fate* is the misfortune in the result of fate or chance.
*The difference between of things seem to be or reality.

## Examples
*In Shakespeare's play *Romeo and Juliet*, Juliet takes a potion that will put her to sleep, making her look dead. She does this in the hopes of being reunited with Romeo. He incorrectly learns of her death, and kills himself. This is an example of dramatic irony, as the reader/viewer knows she is not dead, but Romeo does not.
*A common example of cosmic irony could be that a child wants some kind of pudding, and misbehaves to try to get it. The parent withholds it because of the child's behavior.
*Verbal irony can be found in sarcasm, but not just that.
*In Sophocles' play *Oedipus Rex*, Oedipus acts out based on the knowledge of his fate which in turn leads to the fulfillment of the tragic fate. This is an example of how fate plays on irony.

An **assault rifle** is a rifle that has a removable magazine, automatic-fire and semi-automatic modes, and uses intermediate cartridges. These cartridges include the 5.56 NATO and 7.62x39mm cartridges. Intermediate cartridges have more power and penetration than pistol cartridges fired by submachine guns, and less than the larger battle rifle cartridges.

Two rifles made in Italy and Russia before World War I are sometimes called assault rifles. The Germans were the first to use **assault rifles** in large numbers. 

Common examples of "assault rifles" are the English L85, Russian AK-47, the American M16.

The term “assault rifle” comes from the firearm **Sturmgewehr 44 (StG 44)**, translated to “Assault Rifle 1944”. The armed forces of other sovereign states adopted assault rifles later.

The term "assault rifle" and less commonly "assault weapon" have seen increasing use by American, Canadian and European politicians seeking to limit access to civilian rifles that fire similar or identical rounds to common "assault" or "battle" rifles, such as the 308 Winchester or the 30-06 Springfield.

Alfred Kinsey

**Alfred Charles Kinsey** (June 23, 1894  August 25, 1956) was an American biologist. He was born in Hoboken, New Jersey.

In the first part of his career he was an entomologist specializing in gall wasps of the family Cynipidae. Later, he became famous for the research he did on human sexuality. His research had a great influence on social and cultural values in many parts of the world. It also had an influence on the sexual revolution of the 1960s and 70s.

Kinsey and his co-workers wrote two books which became known as the Kinsey Reports. They were based on thousands of interviews with men (first report), and then women. The aim was to find out how widespread or differentiated human sexual practices were. He developed the **Kinsey Scale** to measure sexual orientation. On one end of the scale, at the value 0, the individual is entirely heterosexual. On the other end, at value 6, he or she has a purely homosexual orientation. Kinsey was bisexual.

Kinsey died of heart disease and pneumonia in Bloomington, Indiana.

A biopic of him, *Kinsey*, was released in 2004.

*Research into sexual behaviour was also conducted by the Masters and Johnson research team: William H. Masters and Virginia E. Johnson.

## Early work 
Kinsey wrote his doctoral thesis on gall wasps. In 1919, Kinsey was awarded a ScD degree by Harvard University, and he accepted an academic post in biology at Indiana University. 

In 1920 he published several papers in the American Museum of Natural History in New York City. The papers introduced the gall wasp to the scientific community and described its phylogeny. Of the more than 18&nbsp;million insects in the museum's collection, some 5&nbsp;million are gall wasps collected by Kinsey.

MiniDisc

minidisc player and disc]]
A **MiniDisc** (**MD**) is a small magneto-optical disk. It is used as a replacement for the Audio cassette. It was developed by Sony to store music. Later it was modified, so it can also store data. The music it stores is compressed in some way, like an MP3. Recent Hi-MD models have the option to not compress audio, and offer audio identical to CD-quality. 

MiniDisc recorders allow the user to modify the contents of (recordable) disks. That way, tracks can be split, combined or rearranged. Audio tracks can be input while a live recording is in progress, too, for example, while recording a live concert or interview via the microphone input on a MiniDisc recorder.

Explosion

An **explosion** is a fast increase in volume and increase in energy made available.  It normally makes high temperatures and makes gases. Many natural events can make explosions, such as lightning, volcanic eruptions, meteors, and supernovae. People make explosions mostly by using chemical explosive materials. 

A chemical explosion starts pressure waves in the medium where it happens.  Explosions are categorized as deflagrations if the pressure waves are subsonic and detonations if they are supersonic.  When a detonation happens, the resulting pressure waves are named shock waves.

## Unintentional explosions
**Unintentional explosions** can be caused when chemicals are mixed together, or when pressurized containers or flammable materials are heated or exposed to flames as in the Texas City disaster. To cause an explosion, pressure does not have to be present but is always a result of an explosion.

Several safety measures are used to prevent unintentional explosions.  Many countries require that chemicals, fuels, and pressurized containers that may explode be labelled with warning labels.  As well, many countries have regulations restricting the possession and use of potentially explosive materials so they will only go to appropriate industrial and research uses.  Transportation regulations require potentially explosive chemicals, fuels, and pressurized containers to be transported safely.

## Intentional explosions
**Intentional explosions** are caused when armies fire artillery or when air forces drop bombs on enemies.  Military engineers handle explosives and arrange intentional explosions during wartime.  Intentional explosions are also used by civilians in *demolition*.  They break up old and obsolete buildings and bridges, and break rock and stone for construction.  Explosions are made for activities such as mining, construction, and large-scale civil engineering projects such as building tunnels, roads, railways, and dams.

Niobium

**Niobium** is a chemical element. It is sometimes named **columbium**. It has the chemical symbol **Nb**. It has the atomic number 41. It is a  metal. Niobium is hard and grey. It is . In chemistry it is placed in a group of metal elements named the transition metals. Niobium was discovered in a variety of a mineral called columbite (now called niobite). Niobite is an ore of niobium. 

Niobium is considered a *technology-critical element*. It is used in alloys, such as to make special steels and strong welded joints. Less than 0.1% of Niobium significantly improves the strength of steel. It is in the superconducting alloys used in MRI scanners, which are one of the most important medical inventions of the modern age.

## Name and history 
In 1801, Charles Hatchett claimed to have discovered a new chemical element in a sample from the United States. He named the mineral "columbite" and his element "columbium", after Columbia, another name for the United States. However, chemists were uncertain that columbium was a new element because of its similarity to tantalum. William Hyde Wollaston claimed that columbium and tantalum were the same element. Other chemists claimed that up to five new elements were in these minerals, one of which was named "niobium".

It took until 1864 to make pure tantalum and niobium and show there were only two elements in these minerals. One of these two elements was named "tantalum", but this showed that "niobium" and "columbium" were the same element. Americans preferred the name "columbium", while "niobium" was more common in Europe. Almost a hundred years later, IUPAC decided on the name niobium as part of an effort to make the names of chemical elements more universal.

## Production 
Niobium and tantalum are in the same group, so their chemistry is very similar. Their ores make a solid solution series called coltan. Niobium and tantalum are both extracted from coltan by leaching. Pyrochlore is another important niobium ore, which can be reduced by aluminium or carbon to make ferroniobium..

Indium

]]
**Indium** is a chemical element. It has the chemical symbol **In**. It has the atomic number 49. It is a  metal which is soft, malleable, and poor (post-transition). Indium looks like zinc. Pieces of indium can easily be joined by pushing one piece into another. The chemistry of indium is quite like aluminium or gallium. Zinc ores are the main source of indium.

## Uses 
The main use of indium is in the chemical compound indium tin oxide in liquid crystal displays. It is also used in very thin layers as a lubricant. In World War II it was used to coat bearings in aircraft.

Like other group 13 elements, indium is used to make III-V semiconductors. Indium phosphide and indium arsenide are binary (two-element) semiconductors made with indium. It is also used as a dopant for other semiconductors like boron nitride and silicon.

Francium

**Francium** is a chemical element with the chemical symbol **Fr** and an atomic number of 87.  It is a metal.  In chemistry it is placed in a group of metal elements named the alkali metals.  Francium is very radioactive.  It is in very small amounts in uranium and thorium ores.  It has the lowest electronegativity and electron affinity of all the chemical elements.

Francium reacts violently with water, as do all of the elements in group 1 on the periodic table.

Francium is one of the hardest to find elements on the planet Earth.  It is estimated that there are only about 15&nbsp;grams or half an ounce in the Earth's crust at a single time.

Although chemists knew the element number 87 in the periodic table should exist, it was a long time before it was discovered.  In the early 1900s, nearly all boxes on the periodic table had been filled. Chemists knew that one element had been found to fit into each box. Francium was discovered in 1939 by a French chemist called Marguerite Perey. She named it after her home country, France.

## Isotopes
There are 34 known isotopes of francium ranging in atomic mass from 199 to 232. Francium-223 and francium-221 are the only isotopes that occur in nature.

Francium-223 is the most stable isotope, with a half-life of 21.8 minutes. Francium-223 is the fifth product of the actinium decay series as the daughter isotope of actinium-227. Francium-223 then decays into radium-223 by beta decay (1.149 MeV decay energy), with a minor (0.006%) alpha decay path to astatine-219 (5.4 MeV decay energy).

Francium-221 has a half-life of 4.8 minutes. It is the ninth product of the neptunium decay series as a daughter isotope of actinium-225. Francium-221 then decays into astatine-217 by alpha decay (6.457 MeV decay energy).

Rhenium

**Rhenium** is a chemical element.  It has the chemical symbol **Re**.  It has the atomic number 75.  It is a  noble metal.  It is silver white.  In chemistry it is placed in a group of metal elements called the transition metals.  The chemistry of rhenium is similar to manganese. Discovered in 1908, rhenium was the second-last stable element to be discovered ('stable' meaning not radioactive). It was named after the river Rhine in Europe.

Nickel-based superalloys of rhenium are used in the combustion chambers, turbine blades, and exhaust nozzles of jet engines. These alloys contain up to 6% rhenium, making jet engine construction the largest single use for the element. The second-most important use is as a catalyst: rhenium is an excellent catalyst for hydrogenation and isomerization. 

Rhenium found as a by-product of molybdenum refinement. 

Rhenium is used in some manganese alloys.  Rhenium-molybdenum alloys are superconductors.

## History 
Rhenium was discovered by Walter Noddack, Ida Noddack, and Otto Berg in Germany. In 1925, they reported that they detected the element in a platinum ore and in the mineral columbite. They also found rhenium in gadolinite and molybdenite. In 1928, they were able to remove 1 g of the element from 660 kg of molybdenite.

## Isotopes 
Rhenium has one stable isotope which is rhenium-185. Rhenium that is found in nature is made up of 37.4% rhenium-185 and 62.6% rhenium-187. Rhenium has 33 known radioisotopes. They range from rhenium-160 to rhenium-194. The longest-lived radioisotope of rhenium is rhenium-183 which have a half-life of 70 days.

## Occurence 
Rhenium is one of the rarest elements in Earth's crust. It the 77th most abundant element in the Earth's crust. Rhenium may not be found free in nature.

## Production 
Commercial rhenium is gotten from molybdenum roaster-flue gas. Some molybdenum ores contain 0.001% to 0.2% rhenium.

## Uses 
Nickel-based superalloys of rhenium are used in the combustion chambers, turbine blades, and exhaust nozzles of jet engines. Rhenium is used in superalloys, such as CMSX-4 (2nd generation) and CMSX-10 (3rd generation). These superalloys are used in industrial gas turbine engines like the GE 7FA. Rhenium filaments are used in mass spectrometers, ion gauges and photoflash lamps in photography. Rhenium-platinum alloys are used as a catalyst for catalytic reforming. Rhenium-188 and Rhenium-186 are used to treat of liver cancer.

Néstor Kirchner

**Néstor Kirchner** (born **Néstor Carlos Kirchner Ostoić**, 25 February 1950 – 27 October 2010) was an Argentine lawyer and politician who was the 54th President of Argentina from 2003 to 2007. Previously, he was the acting president of Argentina from May to December 2003. After his presidency, Kirchner became the First Gentleman of Argentina from 2007 until his death in 2010. As member of the Justicialist Party, he previously served as Governor of Santa Cruz Province from 1991 to 2003, and mayor of Río Gallegos from 1987 to 1991. He later served as the first ever (and still only) First Gentleman of Argentina during the first tenure of his wife, Cristina Fernández de Kirchner. Ideologically, he identified himself as a Peronist and a progressive, with his political approach called Kirchnerism.

During his presidency, Kirchner was considered Argentina's fixer as he led Argentina out of instability and violence following the December 2001 Argentine Riots. He made many Argentine's experience, stability and prosperity. Corruption and Inflation lowered as well.

In 2007, Kirchner handed over the presidency to his wife, Cristina Fernández de Kirchner. This was the second time a male Argentine presidnet handed over power to his wife, after Juan Perón and Isabel Peron in 1974 where Isabsl took power after Juan died. 

After handing power to his wife, Kirchner became the First Gentleman of Argentina. On 27 October 2010, Kirchner died of a heart attack in El Calafate, Santa Cruz at the age of 60.

Guaraní alphabet

The **Guaraní alphabet** is a system used to write the Guaraní language. The Guaraní language is used in Paraguay and some countries near it. The alphabet has 35 letters. These are:
:A, Ã, CH, E, Ẽ, F, G, G̃, H, I, Ĩ, J, K, L, M, MB, N, ND, NG, NJ, NT, Ñ, O, Õ, P, R, RR, S, T, U, Ũ, V, Y, Ỹ, ʼ.

"A", "E", "I", "O", "U", "Y" are vowels, just like English. Those letters with tildes on top make the same sound, except more nasal sounding. The apostrophe sounds like a glottal stop. The other letters are consonants.
Tonsillitis

**Tonsillitis** is a disease usually caused by a bacterial infection. It is also known as **pharyngitis**, **laryngitis** and **Tonsillar infection**. Tonsillitis is caused by either a virus or bacteria. It is the inflammation and infection of the tonsils. The tonsils are in the back of the throat. 

The tonsils get inflamed and red. Other symptoms include headaches, fevers, back and neck aches, chills, bad breath (halitosis), weak voice, fatigue, having trouble swallowing, for example. 

There are treatments for tonsillitis. One treatment is antibiotics. Medicines to relieve pain like Tylenol and Advil are also suggested. The tonsils may be removed surgically if it is medically necessary. This operation is called a tonsillectomy. It is the most effective way to get rid of the infection. All kinds of tonsillitis are contagious. Tonsillitis is spread by human contact.

Inflammation

**Inflammation** is the first reaction of the immune system to an infection or irritation. It is an attempt of the immune system to dispel invaders and repair the body. It can happen in many parts of the body and often involves the following five steps:

# The inflamed spot becomes red.
# The inflamed spot becomes hot.
# The inflamed spot begins to swell.
# The inflamed spot begins to feel uncomfortable.
# The inflamed spot might cause surrounding organs to dysfunction.

The first four of these reactions have been known for a long time, since antiquity. Finding them is attributed to Celsus. The last one was added by Rudolf Virchow in 1858.

There are two types of inflammation: acute and chronic. Acute inflammations are more intense but short-lived, while chronic inflammations are less intense but long-lived. Examples of acute inflammation include skin disorders (e.g., psoriasis, dandruff) and arthritis, while chronic inflammation can be responsible for diseases such as cancer, heart disease, type 2 diabetes and Alzheimer's disease. Adoption of healthy diet, physical exercise and rest are some of the ways to reduce Inflammations.

Car rental

airport, Germany.]]
**Car hire** is the act or procedure of hiring (renting) a car, usually for a fee.

The business that provides the car becomes the car hire service provider, and the party who hires the car becomes the car hirer.

A **car hire company** is usually the business that hires out automobiles for fixed periods of time (ranging from as little as hours up to weeks or longer). 

## Location 
They can be found primarily located near airports or busy city areas. The internet is changing the car rental industry with companies that are now called online car rental companies. Travelers can pre-book their rental car online anywhere across the globe directly from the service providers like Hertz, Budget, Alamo, Sixt Rent a Car, Thrifty, Travelauto.com, Dollar, Enterprise Rent-A-Car and Europcar.

## Purpose 
Car rental agencies are mainly for people who need a car for a short period of time, for example travellers who are out of town, people whose cars were damaged or destroyed. Car rental agencies may also rent trucks for self-moving industry 

### Conditions 
Car rentals are subject to many conditions which vary from one brand to another. The vehicle must be returned in a good condition and must not exceed a maximum driven distance, otherwise extra fees may be incurred. Additionally, some companies set up a minimum age for the vehicle driver, which in some cases is as high as 25, even in countries where the minimum legal age to hold a driver's license is much lower. Recent conditions have used GPS technology to limit maximum speeds or driving to specific regions.

## Global market 
North America and Europe are leading the car rental market, followed by Asia-Pacific. North America is dominating the car rental market, owing to the high usage rate of car rental services by daily commuters, office-goers, and tourists in the country. Also, the growing trend of car sharing also boosts the usage of car rental in this region.
