Degrees Brix (symbol °Bx) is the sugar content of an aqueous solution. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. If the solution contains dissolved solids other than pure sucrose, then the °Bx only approximates the dissolved solid content. The °Bx is traditionally used in the wine, sugar, carbonated beverage, fruit juice, and honey industries.
Comparable scales for indicating sucrose content are the degree Plato (°P), which is widely used by the brewing industry, and the degree Balling, which is the oldest of the three systems and therefore mostly found in older textbooks, but also still in use in some parts of the world.
A sucrose solution with an apparent specific gravity (20°/20 °C) of 1.040 would be 9.99325 °Bx or 9.99359 °P while the representative sugar body, the International Commission for Uniform Methods of Sugar Analysis (ICUMSA), which favors the use of mass fraction, would report the solution strength as 9.99249%. Because the differences between the systems are of little practical significance (the differences are less than the precision of most common instruments) and wide historical use of the Brix unit, modern instruments calculate mass fraction using ICUMSA official formulas but report the result as °Bx.
Zzyzzyxx is a stand up coin operated arcade game developed by Advanced Microcomputer Systems, and manufactured by Cinematronics in 1982. It was retitled as Brix for release as a conversion kit in 1983. The title screen and marquee were the only changes.
The object of the game is to guide the hero, named Zzyzzyxx, through a moving maze of bricks to collect gifts and bring them to the fair-haired Lola, the object of his affection. Zzzyzzyxx is opposed by the evil Rattifers, named Boris, Bluto and Smoot, who will try to intercept him as he makes his way through the maze. Zzyzzyxx can collect a helmet in the maze, which can be used to imprison a Rattifer inside a brick, or to break a brick in the row above to move through the maze. As the levels progress, Zzyzzyxx must avoid crumbling bricks, rising missiles, and dropping bombs. The game has a 1up player score and laps tallied at the top of the screen.
BriX is a database containing some protein fragments from 4 to 14 residue from non-homologous proteins.
There are very few loops registered in Brix, so to address this issue, Loop Brix was added to the system to help structure non-regular elements. These are organized with clustering of end to end elements and their distance between residues that flank the top of the peptide. Currently the system also encourages user submitted structures to be uploaded so long as they match Brix classes.
