Ivory

Ivory is a hard, white material from the tusks (traditionally elephant's) and teeth of animals, that can be used in art or manufacturing. It consists mainly of dentine (inorganic formula Ca₁₀(PO₄)₆(CO₃).H₂O)), one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, "ivory" can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed. It has been valued since ancient times for making a range of items, from ivory carvings to false teeth, fans, and dominoes.Elephant ivory is the most important source, but ivory from mammoth, walrus, hippopotamus, sperm whale, killer whale, narwhal and wart hog are used as well. Elk also have two ivory teeth, which are believed to be the remnants of tusks from their ancestors.

Ivory (soap)

"Ivory" is a personal care brand created by the Procter & Gamble Company (P&G), including varieties of a white and mildly scented bar soap, that became famous for its claim of purity and for floating in water. Over the years, the brand has been extended to other varieties and products.

History

As Ivory is one of P&G's older products (first sold in 1879), P&G is sometimes called "Ivory Towers" and its factory and research center in St. Bernard, Ohio, is named "Ivorydale".

In 1840 the J.B. Williams Company in Glastonbury, Connecticut manufactured soap under the name Ivorine. Williams decided to focus on its shaving soap and sold Ivorine to Procter & Gamble, who later renamed it Ivory.

Ivory bar soap is whipped with air in its production and floats in water. According to an apocryphal story, later discounted by the company, a worker accidentally left the mixing machine on too long and the company chose to sell the "ruined" batch, because the added air did not change the basic ingredients of the soap. When appreciative letters about the new, floating soap inundated the company, P&G ordered the extended mix time as a standard procedure. However, company records indicate that the design of Ivory did not come about by accident. In 2004, over 100 years later, the P&G company archivist Ed Rider found documentation that revealed that chemist James N. Gamble, son of the founder, had discovered how to make the soap float and noted the result in his writings.

List of Death Note episodes

Death Note is a 37-episode anime series based on the manga series of the same title written by Tsugumi Ohba and illustrated by Takeshi Obata. Death Note aired in Japan on the Nippon Television (NTV) network every Tuesday, from October 3, 2006, to June 26, 2007. The plot of the series primarily revolves around high school student Light Yagami, who decides to rid the world of evil with the help of a supernatural notebook titled Death Note. This book causes the death of anyone whose name is written in it and is passed on to Light by the God of Death (or Shinigami) Ryuk after he becomes bored within the Shinigami world.

A three-hour "Director's Cut" compilation TV special, titled "Death Note: Relight: Visions of a God", aired on NTV a few months after the anime concluded. Although advertised to be the "complete conclusion", the popularity of the series inspired the release of a second TV special, titled "Death Note: Relight 2: L's Successors" nearly a year later. These specials recap the first and second arcs of the anime respectively, with new scenes added to fill in any plot holes resulted from omitted footage.

Facebook structure

News Feed

On September 6, 2006, Ruchi Sanghvi announced a new home page feature called News Feed. Originally, when users logged into Facebook, they were presented with a customizable version of their own profile. The new layout, by contrast, created an alternative home page in which users saw a constantly updated list of their friends' Facebook activity. News Feed highlights information that includes profile changes, upcoming events, and birthdays, among other updates. This has enabled spammers and other users to manipulate these features by creating illegitimate events or posting fake birthdays to attract attention to their profile or cause. News Feed also shows conversations taking place between the walls of a user's friends. An integral part of the News Feed interface is the Mini Feed, a news stream on the user's profile page that shows updates about that user. Unlike in the News Feed, the user can delete events from the Mini Feed after they appear so that they are no longer visible to profile visitors. In 2011 Facebook updated the News Feed to show top stories and most recent stories in one feed, and the option to highlight stories to make them top stories, as well as to un-highlight stories. In response to users' criticism, Facebook later updated the News Feed to allow users to view recent stories first.
