5-(2-Aminopropyl)indole (5-API, 5-IT, PAL-571) [1] is an indole and phenethylamine derivative with empathogenic effects. Its preparation was first reported by Albert Hofmann in 1962. [ 2 ] It is a designer drug that has been openly sold as a recreational drug by online vendors since 2011.
Corrosion under insulation (CUI) is a severe form of localized external corrosion that occurs in carbon and low alloy steel equipment that has been insulated. This form of corrosion occurs when water is absorbed by or collected in the insulation.
Pipe drift is a measure of the roundness or eccentricity of the inside wall of a pipe. "API drift" refers to primary specifications set forth in API Specification 5CT (ISO 11960), "Specification for Casing and Tubing".

The analytical profile index (API) was invented in the 1970s in the United States by Pierre Janin of Analytab Products Inc. [2] The API test system is currently manufactured by bioMérieux. [3] The API range introduced a standardized and miniaturized version of existing techniques, which were considered complicated to perform and difficult to read.
In granulometry, the particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. [1]
571.2 617.2 667.2 713.2 811.2 863.2 868.2 Kozak grain sizes ranged from 0.3 to 1 mm diameter and the density was 0.54 grams ⋅ cm −3. Kozak, M.I. Zhur. Tekh. Fiz., 22 (1), 73–6, 1952. By comparison Sinel'nikov powder is a powder in a vacuum, gran sizes range from 100 to 200 micrometers, the powder density is 1.35 g per cm −3.
API testing is a type of software testing that involves testing application programming interfaces (APIs) directly and as part of integration testing to determine if they meet expectations for functionality, reliability, performance, and security. [1] Since APIs lack a GUI, API testing is performed at the message layer. [2]
