5. The third number ("K value") is the equivalent content of potassium oxide K 2 O. [3] For example, a 15-13-20 fertilizer would contain 15% by weight of nitrogen, 13% by weight of P 2 O 5, 20% by weight of K 2 O, and 52% of some inert ingredient.
Police code. A police code is a brevity code, usually numerical or alphanumerical, used to transmit information between law enforcement over police radio systems in the United States. Examples of police codes include "10 codes" (such as 10-4 for "okay" or "acknowledged"—sometimes written X4 or X-4), signals, incident codes, response codes, or ...
The police version of ten-codes is officially known as the APCO Project 14 Aural Brevity Code. [ 1 ] The codes, developed during 1937–1940 and expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO), allow brevity and standardization of message traffic.
United States. [] In the United States, response codes are used to describe a mode of response for an emergency unit responding to a call. They generally vary but often have three basic tiers: Code 3: Respond to the call using lights and sirens. Code 2: Respond to the call with emergency lights, but without sirens.
UAN. UAN is a solution of urea and ammonium nitrate in water used as a fertilizer. The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30 °C) and can therefore only be used in liquid fertilizers.
The main use of calcium cyanamide is in agriculture as a fertilizer. [3] In contact with water, it hydrolyses into hydrogen cyanamide which decomposes and liberates ammonia: [5] CaCN 2 + 3 H 2 O → 2 NH 3 + CaCO 3. It was used to produce sodium cyanide by fusing with sodium carbonate: CaCN 2 + Na 2 CO 3 + 2 C → 2 NaCN + CaO + 2 CO
NPK ratings consist of three numbers separated by dashes (e.g., 10-10-10 or 16-4-8) describing the chemical content of fertilizers. [ 29 ] [ 30 ] The first number represents the percentage of nitrogen in the product; the second number, P 2 O 5 ; the third, K 2 O. Fertilizers do not actually contain P 2 O 5 or K 2 O, but the system is a ...
In April 2001, an attendant at a donut shop spotted a counterfeit $20 bill that Chase tried to pass him. He alerted an off-duty Boston police officer, who then arrested Chase and Felton. A subsequent search of Felton's apartment yielded large quantities of evidence, including self-drawn cartoons of Felton blowing up the Boston offices of the ...
