Nova

A nova (plural novae or novas) is a cataclysmic nuclear explosion on a white dwarf, which causes a sudden brightening of the star. Novae are not to be confused with other brightening phenomena such as supernovae or luminous red novae. Novae are thought to occur on the surface of a white dwarf in a binary system when they are sufficiently near to one another, allowing material (mostly hydrogen) to be pulled from the companion star's surface onto the white dwarf. The nova is the result of the rapid fusion of the accreted hydrogen on the surface of the star, commencing a runaway fusion reaction.

Development

The development begins with two main sequence stars in a binary relation. One of the two evolves into a red giant leaving its remnant white dwarf core in orbit with the remaining star. The second star—which may be either a main sequence star, or an aging giant one as well—begins to shed its envelope onto its white dwarf companion when it overflows its Roche lobe. As a result, the white dwarf will steadily accrete matter from the companion's outer atmosphere; the white dwarf consists of degenerate matter, so the accreted hydrogen does not inflate as its temperature increases. Rapid, uncontrolled fusion occurs when the temperature of this accreted layer reaches ~20 million kelvin, initiating a burn via the CNO cycle.

Storyline

Graham (Noriega) suffers from severe amnesia and cannot remember what he has done hours after he has done it. Consequently, he must write everything down; who he knows, where he should be, even where he works. His boss takes advantage of his disability and manipulates him into having sex with her. Graham meets a temp called Irène and begins a relationship with her, which is difficult as he never remembers who she is. To help him remember, Irène writes her name on his chest with a marker pen.

A little boy called Antoine is frequently seen in the same places Graham happens to be. Graham doesn't notice this due to his condition, but it is clear to the viewer that the child is of significance. Through the machinations of his boss, Graham's notebook is stolen leading him into a misadventure to try to recover it.

In a state of confusion, Graham is left wandering naked on a beach where he falls asleep. During the night the little boy, Antoine curls up next to him to and awakens Graham. Graham remembers Antoine as being his son. Antoine tells Graham that his wife, Isabelle, forgives him for his relationship with Irène as she knows he cannot help forgetting his family. Graham and Antoine are approached on the beach by the police who are concerned that a young boy is with a naked man.

NOVO7

The NOVO7 is a series of Android tablet computers manufactured by the Chinese company Ainol Electronics. The "7" represents the size of the tablet's screen (7 inches); Ainol's other products include the Novo 5 and Novo 8.

History

The first tablets in the Novo 7 line were the Novo 7 Basic and Novo 7 Advanced, released in early 2011. Unlike most competing tablets, the Novo 7 Basic used a MIPS based CPU (1 GHz Ingenic JZ4770 XBurst), while the Advanced had a more common ARM CPU. Both had 800x480 pixel touch screens and were launched with Android 2.2, although the company later released updates to Android 3 and Android 4.

The company released the Novo 7 Paladin in late 2011, which became the world's first Android 4.0 (Ice Cream Sandwich) tablet. Its specifications were similar to the Novo 7 Basic, having a 7-inch touch screen, 1 GHz MIPS processor, 512 MB RAM, 8 to 16 GB of internal flash storage, external microSDHC slot, miniUSB, and Wi-Fi (802.11 b/g/n). Two more tablets, the Aurora and the Elf, were added to the range soon afterwards; both of these tablets used ARM CPUs.
