Trimethylamine N-oxide. Trimethylamine N-oxide (TMAO) is the organic compound in the class of amine oxides with the formula (CH3)3NO. This colorless solid is usually encountered as the dihydrate. It is a product of the oxidation of trimethylamine, a common metabolite in animals.
Prism fusion range. The prism fusion range (PFR) or fusional vergence amplitude is a clinical eye test performed by orthoptists, optometrists, and ophthalmologists to assess motor fusion, specifically the extent to which a patient can maintain binocular single vision (BSV) in the presence of increasing vergence demands.
Aircraft range The maximal total range is the distance an aircraft can fly between takeoff and landing, as limited by fuel capacity in powered aircraft, or cross-country speed and environmental conditions in unpowered aircraft.
