2-Cyanoguanidine can also exist in a zwitterionic form via a formal acid–base reaction among the nitrogens. Loss of ammonia (NH 3 ) from the zwitterionic form, followed by deprotonation of the remaining central nitrogen atom, gives the dicyanamide anion, [N(CN) 2 ] − .
The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the following table for angles from 0° to 45°. [ 1 ] In the table below, the label "Undefined" represents a ratio 1 : 0. {\displaystyle 1:0.}
A line impedance stabilization network (LISN) [1] is a device used in conducted and radiated radio-frequency emission and susceptibility tests, as specified in various electromagnetic compatibility (EMC)/EMI test standards (e.g., by CISPR, International Electrotechnical Commission, CENELEC, U.S. Federal Communications Commission, MIL-STD, DO-160 Sections 20-21-22).
In mathematics, the Fibonacci numbers form a sequence defined recursively by: = {= = + > That is, after two starting values, each number is the sum of the two preceding numbers.
Palmitoylcarnitine is an ester derivative of carnitine involved in the metabolism of fatty acids.During the tricarboxylic acid cycle (TCA), fatty acids undergo a process known as β-oxidation to produce energy in the form of ATP. β-oxidation occurs primarily within mitochondria, however the mitochondrial membrane prevents the entry of long chain fatty acids (>C10), so the conversion of fatty ...
Helvering v. Bruun, 309 U.S. 461 (1940), was an income tax case before the Supreme Court of the United States.It is notable (and thus appears frequently in law school casebooks) for holding that under section 22(a) of the Revenue Act of 1932, income need not be in the form of cash for it to be taxable.
