Ammonium persulfate (APS) is the inorganic compound with the formula (NH 4) 2 S 2 O 8. It is a colourless (white) salt that is highly soluble in water, much more so than the related potassium salt. It is a strong oxidizing agent that is used as a catalyst in polymer chemistry, as an etchant, and as a cleaning and bleaching agent. [1]
Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion ).
It is endogenously synthesized by organisms via the phosphorylation of adenosine 5′-phosphosulfate (APS), an intermediary metabolite. [2] In humans such reaction is performed by bifunctional 3′-phosphoadenosine 5′-phosphosulfate synthases ( PAPSS1 and PAPSS2 ) using ATP as the phosphate donor.
The International Organization for Standardization publishes equivalent standards (ISO 11075 and ISO 11078), defining the same four types. De-icing fluids containing thickeners (types II, III, and IV) are also known as anti-icing fluids, because they are used primarily to prevent icing from re-occurring after an initial deicing with a type I fluid.
Low Advance Ratio (J < 1): When the advance ratio is low, the vehicle is moving forward slowly relative to the propeller speed. This usually happens at low speeds or when the propeller is turning very fast. High Advance Ratio (J > 1): When the advance ratio is high, the vehicle is moving forward quickly compared to the propeller's rotational speed.

In aviation, equivalent airspeed (EAS) is calibrated airspeed (CAS) corrected for the compressibility of air at a non-trivial Mach number. It is also the airspeed at sea level in the International Standard Atmosphere at which the dynamic pressure is the same as the dynamic pressure at the true airspeed (TAS) and altitude at which the aircraft ...
Here the unit cell (equivalent to 3 primitive unit cells) is a hexagonal prism containing six atoms (if the particles in the crystal are atoms). Indeed, three are the atoms in the middle layer (inside the prism); in addition, for the top and bottom layers (on the bases of the prism), the central atom is shared with the adjacent cell, and each ...
