Australian Gold Nugget

The Australian Gold Nugget is a gold bullion coin minted by the Perth Mint. The coins have been minted in denominations of 1/20 oz, 1/10 oz, 1/4 oz, 1/2 oz, 1 oz, 2 oz, 10 oz, and 1 kg of 24 carat gold. They have legal tender status in Australia and are one of few legal tender bullion gold coins to change their design every year, another being the Chinese Gold Panda. This and their limited annual mintage may, unlike for many other bullion coins, raise their numismatic value over the value of gold used.

The Gold Nugget series was introduced in 1986 by Gold Corporation, a company wholly owned by the government of Western Australia, more commonly known by its trading name The Perth Mint. This issue of coins had two unique features: a "two-tone" frosted design effect, and individual hard plastic encapsulation of each coin. These features were unusual for a standard bullion coin and gave the Nugget a unique market niche.

From 1986 to 1989, the reverse of these coins pictured various Australian gold nuggets. With the 1989 proof edition, the design was changed to feature different kangaroos, a more world-recognised symbol of Australia. The coins are today sometimes referred to as "gold kangaroos".

Brain

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead. The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.

Physiologically, the function of the brain is to exert centralized control over the other organs of the body. The brain acts on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated responses to changes in the environment. Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information integrating capabilities of a centralized brain.

Brain (novel)

Brain is a medical thriller written by Robin Cook. It describes how a future generation of computers will work hard-wired to human brains.

Plot

The story starts with a girl Kathereine Collins going to a private GYN clinic, located in Manhattan, New York, where she is undergoing treatment for some Gynac ailments. Simultaneously she has started having seizures where in she smells a repulsive and oddly familiar odor and then loses consciousness. She wants to withdraw her records from this clinic and move onto her hometown to her family doctor. While on her way back, she faints at the elevators. The next scene shows her parents visiting her apartment and the cops searching the room as she has been missing for some days now. The story revolves around the protagonist Dr. Martin Philips from then on, who is a doctor in neuroradiology at the NYC medical center. Dr. Martin Philips, a 41-year-old neuroradiologist is involved in creating a self-diagonstic x-ray machine, along with Michaels, who is a researcher graduating from MIT and also head of the department of artificial intelligence. Dr. Philips's girlfriend and colleague Dr. Denise Sanger (28 years old) is also involved in the same hospital.

List of Arthur characters

This is a list of characters that are featured in the PBS Kids television show, Arthur. The show is based on the book series by Marc Brown.

Arthur, the title character, is the main character of the series. The main supporting characters are D.W., Buster, Francine, Muffy, Binky, the Brain, Mr. Ratburn, and Arthur's parents. Over the years, the roles of each character have changed as more episodes focused on characters besides Arthur or D.W., most notably Buster, Francine, Muffy, Binky, and the Brain. Minor supporting characters such as Sue Ellen, George, and Fern have also had expanded roles in the series.

Like The Simpsons and many other cartoon series, characters in the Arthur series do not age in order to maintain the status quo, although their universe does age in parallel to the real world. Ages presented in this article are their ages in most of the episodes. Their ages do change occasionally and temporarily like in flashback scenes, future scenes, and birthday parties.
