He managed the Electronics Mega-Mart in Queens as an occupation. As Percy described him in The Lightning Thief, he "was nice the first thirty seconds we knew him, then showed his true colors as a world-class jerk." During summer break from school, Gabe asks him for money for beer and for his poker games with his friends. Supposedly he can easily guess how much money a person has. It is implied that, at least once, he hit Percy's mother. Grover later tells Percy that Sally (Percy's mother) married Gabe to protect Percy from monsters who would have tracked him down otherwise. He smelled so "repulsively human" that his smell hid Percy's demigod scent from monsters. If she had not married him, monsters would have found Percy sooner
. At the end of Book 1, he is turned to stone by Percy's mother (using Medusa's severed head) and sold as a statue, "The Poker Player", earning lots of money in the process.
May Castellan - Luke's mother who attempted to become the Oracle.

Paul "Blowfish" Blofis - Sally Jackson's boyfriend and later husband, and thus Percy's stepfather. Percy and his mother reveal to Paul the truth, and at first he only half believes them. When Percy, Nico, and Mrs. O'Leary come unexpectedly into Sally's apartment, Paul fully believes, and thinks it's "awesome!". Paul turns out to be an excellent swordsman due to the fact that he was a Shakespearian actor in college and assists in the fight to save Olympus in The Last Olympian. He asks Percy for permission before proposing to Percy's mother.
 Preacher - A preacher who raised money supposedly for orphans and spent it instead on his mansion until he was caught by the police.

Rachel Elizabeth Dare - A clear-sighted mortal girl who is able to see through the Mist. She is first encountered by Percy during The Titan's Curse as he flees from the skeletons summoned by Atlas. After mistaking her for a monster and realizing she is human, Percy discovers that she can see through the mist. She leads the skeletons away from Percy. Rachel goes to the same school as Percy in "The Battle of the Labyrinth," realizing that the cheerleaders are actually empousai. In The Battle of the Labyrinth, she aids Annabeth and Percy by guiding them through the labyrinth to Daedalus's workshop. From there she, Percy, Annabeth, and Nico escape, only to enter again to locate Grover and Tyson. She is present at the deathbed of Lord Pan and, like the others, takes part of his essence within her. By throwing her hairbrush at Kronos, she provided enough of a distraction for Percy to escape the Titan Lord's time manipulation. It is hinted throughout the series that she harbors romantic feelings for Percy
. In The Last Olympian, she begins having strange visions and becomes the new Oracle of Delphi after Hades's curse is lifted, under the guidance of Chiron and Apollo. Her first act as the Oracle is to deliver the Great Prophecy of the next generation of heroes.
Sally Jackson - The daughter of Jim and Laura Jackson. She is the mother of Percy and she was married to "Smelly" Gabe." She then turned him to stone with the head of Medusa, and married Paul Blofis in the fifth book. In the beginning of the series, it is indicated that Sally works at a candy shop called "Sweet on America" and said that she wanted to be an author when she was young. In the third book, Percy guesses that Sally can see through the Mist and he believes that this was probably the reason Poseidon took interest in her. In the first book, she was thought to be killed by the Minotaur. Later on, it was discovered that she survived and that she was still alive in the clutches of Hades. She was freed once Percy gave the Helm of Darkness (which was also stolen by Luke) to the Furies.
William Dare - He is Rachel Elizabeth Dare's father, who first appears in The Last Olympian. He owns a land developing company and is very wealthy. His family lives in a mansion in Brooklyn, where Rachel lives on the top floor. Rachel hates her father because of his job, but he seems to care about her. He said that he and her mother had really been looking forward to the vacation, but, according to Rachel, they both hate the beach, and are just too stubborn to admit it. He supported Rachel's going to finishing school. He walked into Rachel's room in Percy's dream, wearing pajamas with "WD" monogrammed on the pocket.

Aemilianus or Aemilian (–253) was Roman emperor for eighty-eight days in 253 AD.

Early life 
Aemilianus was born around 207 or around 214. The Epitome de Caesaribus (a Latin history) and Zonaras (a Greek historian) say that Aemilianus was born at this time and at Djerba, an island in the Mediterranean Sea near Africa, part of the Roman Empire.

Aemilianus was not from the nobility, and may have been from among the Moorish people.

Aemilianus was a senator and was a Roman consul, either in 252 or 253. He was also governor () for the Roman province of Moesia Superior.

Emperor 
The Roman army made Aemilianus emperor in Moesia in July or August 253. The Roman Senate agreed that Aemilianus was emperor after the emperor Trebonianus Gallus died in August 253.
After defeating the Goths (a barbarian tribe) in modern-day Bulgaria, his soldiers proclaimed him as an emperor instead of Trebonianus Gallus, the emperor at the time. After defeating Gallus in battle at Interamna (Northern Italy), he captured the capital city of the empire, Rome.

When the governor of Roman Germany, Valerianus, arrived in Italy bringing troops to help Trebonianus Gallus, Aemilianus's own troops killed Aemilianus. They did not want a civil war and Valerian had a bigger army than Aemilianus.

Death 
Soldiers in Aemilianus's army killed Aemilianus at Spoletum in the Italian Peninsula (Spoleto, Italy).

Afghanistan at the Olympics is a history which includes 13 games in 12 countries and 100+ athletes. Since 1936, Afghanistan has contributed to the growth of the "Olympic Movement".

The International Olympic Committee's official abbreviation for Afghanistan is AFG.

History
The Afghanistan National Olympic Committee was formed in 1935.  It was recognized by the International Olympic Committee in 1936.

Afghanistan's team first competed at the 1936 Summer Olympics in Berlin.  

In 1999, Afghanistan was banned from the Olympics due to its discrimination against women under Taliban rule.  

In the 2004 Summer Olympics two women, Robina Muqim Yaar and Friba Razayee, were the first women to compete for Afghanistan at the Olympics.  Mehboba Ahdyar, a woman in the 2008 Summer Olympics had death threats because of her plan to be in the Games.

A hypodermic needle is a hollow steel tube that is sharpened into a needle so it can be jabbed (inserted) into somebody's body. After it is in, medicine is pushed through the steel needle. The name "hypodermic" comes from two Greek words meaning "below skin".

History 
The Greeks made early use of injection.

Operant conditioning is a form of learning. In it, an individual changes its behaviour because of the consequences (results) of the behaviour. 

The person or animal learns its behaviour has a consequence. That consequence may be
 Reinforcement: a positive or rewarding event. This causes the behaviour to occur more often
 Punishment: a negative or punishing event. This causes the behaviour to occur less often
 Extinction: no event follows, so the behaviour has no consequences. When a behaviour has no consequences, it will occur less frequently.
There are four different contexts in operant conditioning. Here, the terms 'positive' and 'negative' are not used in their basic sense; positive means that something is added, and negative means something is taken away:
 Positive reinforcement (often just "reinforcement") occurs when there is a reward for a form of behaviour. This will increase the frequency at which the behaviour occurs. In the Skinner box experiment, the reward is in the form of food when the rat presses a lever. 
 Negative reinforcement (sometimes "escape") occurs when an aversive stimulus is removed. This will increase the frequency at which the behaviour occurs. In the Skinner box experiment, there was a loud noise, which was removed when the rat pressed the lever.
 Positive punishment occurs when a stimulus is added, which results in the behaviour occurring less often. Example stimuli may be loud noise, electric shock (rat), or a spanking (child).
Negative punishment occurs when a stimulus is taken away, which results in the behaviour occurring less often. An example might be a child's toy taken away after the child does an undesired behaviour.
The idea of operant conditioning was first discovered by Edward Thorndike, and analyzed by B.F. Skinner. 

Operant conditioning is different from Pavlov's classical conditioning. Operant conditioning deals with the voluntary modification of behaviour; classical conditioning with training a reflex.
Thorndike's law of effect 
Operant conditioning, sometimes called instrumental learning, was first studied by Edward L. Thorndike (1874–1949). He observed the behavior of cats trying to escape from home-made puzzle boxes. When first put in the boxes, cats took a long time to escape. With experience, successful responses occurred more frequently, enabling the cats to escape in less time. In his law of effect, Thorndike theorized that behaviours followed by satisfying consequences tend to be repeated, and those that produce unpleasant consequences are less likely to be repeated. In short, some consequences strengthened behavior and some consequences weakened behavior. Thorndike produced the first known learning curves by this procedure. 

B.F. Skinner (1904–1990) worked out a more detailed analysis of operant conditioning. Skinner invented the operant conditioning chamber which let him measure rate of response as a key dependent variable. He used a record of lever presses or key pecks.
Principles of operant conditioning: 
Discrimination, generalization and the importance of context.
Learning takes place in contexts. 
Most behaviour is under stimulus control: a particular response only occurs when an appropriate stimulus is present. 
Stimulus control is effective even if the stimulus has no meaning to the respondent.
Extinction: operant behaviour undergoes extinction when the reinforcement stops. 
The reinforcements only occur when the proper response has been made, and may not occur even then. Behaviours do not weaken and extinguish because of this.
Results depend partly on how often reinforcement is received.
Schedules of reinforcement: the timing of the reinforcements is crucial.
Fixed interval schedule: reinforcers are presented at fixed time periods, provided that the appropriate response is made.
Variable interval schedule: a behaviour is reinforced based on an average time that has expired since the last reinforcement. Ratio schedules:  based on the ratio of responses to reinforcements. 
Fixed interval schedule: reinforcement is delivered after a specific number of responses have been made. The special case of presenting reinforcement after each response is called continuous reinforcement.
Variable interval schedule: the delivery reinforcement is based on a particular average number of responses.

Atrax is a genus of spiders. They have very strong venom. These spiders aggressively defend their territory and chase off attackers who may scare them by making a threat display. Next they will bite. The fastest death occurred in 1927 when a young boy died within fifteen minutes of being bitten. Thirteen deaths were recorded in the fifty years before antivenom was invented for this spider's bite. In English they are sometimes called Sydney Funnel Web spiders because they come from around that part of Australia.

Under the heading "spiders" (Aranae) there are three main groups. One is so very old that only a few species still live on earth. Another is the group that includes the spiders that can be seen making webs or chasing prey almost everywhere in the world. The third group includes the tarantulas and a few other kinds of spiders. The Atrax spiders belong to this third group.
There are also species called "funnel-web spiders" that belong to the second group mentioned above. So they are not close relatives of Atrax, and they are not dangerous. They just have a similar way of making a funnel-shaped web that leads down to some kind of shelter where the spider hides in wait for some insect to eat. Atrax is a very large and very aggressive spider, and these other spiders are from small to medium size and are extremely timid.

Bahrain has been in 6 Summer Olympic Games. They have never been in the Winter Olympic Games. 

Bahrain won their first Olympic medal in the 2012 Summer Olympics. Maryam Yusuf Jamal won a bronze in the women's 1500m run.

Rashid Ramzi won the gold medal in the men's 1,500 meters. Because he used drugs, the IOC took the medal away.

Bangladesh has been in seven Summer Olympic Games. They have never been in the Winter Olympic Games.

No Bangladeshi competitor has qualified for the Olympics; the country sends representatives to the Games thanks to the wildcard process. Bangladesh is the most populous country in the world to have never won an Olympic medal. They have had 27 participants in 3 sports.

Bangladesh Olympic Association head Wali Ullah says that Bangledesh's weak economy is the reason for its poor results in sports.

Hot wings are pieces of chicken that are fried and cooked, then smothered in sauce.  Hot wings can vary in how hot they are, from being mild to very spicy.  They are sometimes called Buffalo Wings because they are thought to have originated from Buffalo, New York.

A threat display is anything that an animal does to scare away other animals. A dog will bare its teeth and growl. A cat will hiss. A snake will coil up, raise its head, and move back and forth to point itself at any big animal that approaches it. 

Many animals have threat displays that make them look bigger. A lion's mane will stand up, making it look much larger and more powerful. Humans may raise both hands, spread wide, above their heads. Bears will stand on their hind legs, raise their front legs, and show their teeth while growling.

Some notable animals have no threat display, but do have a defence all the same. A male horse has a terrific kick backwards, no doubt developed as a defence against predators. People who ride horses have to be told not to walk close behind a male horse, even if they have ridden it before.

Why threat display? Economy, because the threat may go away without a fight.

Brunei, as Brunei Darussalam, was first at the Olympic Games in 1988, with a single official but no athletes. The nation was in the Summer Olympic Games in 1996, 2000 and 2004. Each time it was represented by a single athlete. Brunei has never been in the Winter Olympic Games.  They have never won an Olympic medal.

As of 2010 Brunei, along with Saudi Arabia and Qatar, was one of only three countries to have never sent a female athlete to the Olympic Games. The International Olympic Committee in 2010 announced it would "press" these countries to allow women's participation.

The National Olympic Committee for Brunei was formed in 1984 and recognized by the International Olympic Committee the same year.

An antivenom is a medicine used to protect against a specific venom. (A venom is a poison released by a snake or insect.) Frequently the venom of some creature such as a cobra will be harvested and a little will be injected using a hypodermic needle into a horse every day for a long time. The horse's body will develop an immunity to the venom, so more and more venom from the snake can be injected every day. After the horse is immune, its blood can be drawn little by little to get the part of the blood that makes the horse immune. That part can then be injected into humans who have been bitten by cobras.

There are antivenoms for the very large and very dangerous funnel-web spiders found in Australia, and for the widow spiders (such as the black widow) found all around the world.

The People's Republic of China (PRC) was  first at the 1952 Summer Olympics. That year, the International Olympic Committee (IOC) let both the PRC and the Republic of China (which recently moved to Taiwan after the Chinese Civil War) compete.  The Republic of China withdrew in protest. Because of the political status of China, the PRC was not in the Olympics again until 1980.

The Chinese Olympic Committee was formed in 1910 and recognized in 1979. Before the Chinese Civil War, athletes competed as the Republic of China (ROC) at the Olympics. In 1979, the International Olympic Committee passed a resolution for the ROC team to be called Chinese Taipei, and this opened the door for the PRC to finally join the Olympic movement.

Hong Kong has had a distinct National Olympic Committee since 1950 and has been at the Games since 1952.  After the territory returned to the PRC this has continued, with Hong Kong separate from the rest of the nation under the name Hong Kong, China.
The People's Republic of China hosted the Games one time: the 2008 Summer Olympics in Beijing.

A mutagen is a substance or a process that changes the genetic material of an organism. Mutagens also increase the number of mutations that occur. Many mutagens also cause cancer, so they are also carcinogens. Examples of mutagens are ionizing radiation, many bromine compounds, benzene. A test to detect mutagens is the Ames test.
