Purified water

Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water has been the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, or electrodeionization. Combinations of a number of these processes have come into use to produce water of such high purity that its trace contaminants are measured in parts per billion (ppb) or parts per trillion (ppt). Purified water has many uses, largely in the production of medications, in science and engineering laboratories and industries, and is produced in a range of purities. It can be produced on site for immediate use or purchased in containers. Purified water in colloquial English can also refer to water which has been treated ("rendered potable") to neutralize, but not necessarily remove contaminants considered harmful to humans or animals.

Aqua (video game)

Aqua (also known as Aqua - Naval Warfare) is an arcade-action shooter with tactical elements, driven by a steampunk story in which the vast majority of the world is covered with water. Aqua was developed by Games Distillery on their own proprietary engine and published by Microsoft Game Studios. It was released for the Xbox 360 via Xbox Live Arcade on May 19, 2010. The game is set in an alternate reality where most of the Earth is covered with water and factions war for the remaining pieces of land.

The game received mixed reception from reviewers. Aggregate websites GameRankings and Metacritic report average scores of 66.23% and 61/100, respectively. Critics gave high praise to the game's hand-drawn cutscenes and steampunk setting. Gameplay was received to mixed commentary among reviewers. Critics praised the game's length and some also praised Aqua for attempting to do more than typical twin-stick shooters, but others expressed disappointment in the number of escort missions and lack of online multiplayer.

Gliese 667

Gliese 667 (142 G. Scorpii) is a triple-star system in the constellation of Scorpius lying at a distance of about 6.8 pc (23.6 ly) from Earth. All three of the stars have masses smaller than the Sun. There is a 12th magnitude star close to the other three, but it is not gravitationally bound to the system. To the naked eye, the system appears to be a single faint star of magnitude 5.89.

The system has a relatively high proper motion, exceeding 1 second of arc per year.

Star system

The two brightest stars in this system, GJ 667 A and GJ 667 B, are orbiting each other at an average angular separation of 1.81 arcseconds with a high eccentricity of 0.58. At the estimated distance of this system, this is equivalent to a physical separation of about 12.6 AU, or nearly 13 times the separation of the Earth from the Sun. Their eccentric orbit brings the pair as close as about 5 AU to each other, or as distant as 20 AU, corresponding to an eccentricity of 0.6. This orbit takes approximately 42.15 years to complete and the orbital plane is inclined at an angle of 128° to the line of sight from the Earth. The third star, GJ 667 C, orbits the GJ 667 AB pair at an angular separation of about 30", which equates to a minimum separation of 230 AU.
