Hentriacontylic acid-Hentriacontylic acid-Hentriacontylic acid (also hentriacontanoic acid, henatriacontylic acid, or henatriacontanoic acid) is a carboxylic saturated fatty acid. | milkshake721/2.1M-wiki-STEM |
Hentriacontylic acid-Sources-Hentriacontylic acid can be derived from peat wax and montan wax.
The olefin triacontene-1 can be reacted to yield linear n-henatriacontanoic acid. | milkshake721/2.1M-wiki-STEM |
Triolein-Triolein-Triolein is a symmetrical triglyceride derived from glycerol and three units of the unsaturated fatty acid oleic acid. Most triglycerides are unsymmetrical, being derived from mixtures of fatty acids. Triolein represents 4–30% of olive oil.Triolein is also known as glyceryl trioleate and is one of the... | milkshake721/2.1M-wiki-STEM |
Maximum satisfiability problem-Maximum satisfiability problem-In computational complexity theory, the maximum satisfiability problem (MAX-SAT) is the problem of determining the maximum number of clauses, of a given Boolean formula in conjunctive normal form, that can be made true by an assignment of truth values to the... | milkshake721/2.1M-wiki-STEM |
Maximum satisfiability problem-Example-The conjunctive normal form formula (x0∨x1)∧(x0∨¬x1)∧(¬x0∨x1)∧(¬x0∨¬x1) is not satisfiable: no matter which truth values are assigned to its two variables, at least one of its four clauses will be false.
However, it is possible to assign truth values in such a way as to make three... | milkshake721/2.1M-wiki-STEM |
