Light irradiates one light incident position on the surface of a scattering-absorption body. The light that propagates through the interior of the scattering-absorption body is detected at one light detecting position on the surface of the scattering-absorption body. On the basis of a light detection signal, a temporal profile of the light intensity of the detected light is acquired, and on the basis of the temporal profile, an mean optical path length of the light in the interior of the scattering-absorption body and information relating to the amount of substance to be measured in a region to be measured are calculated. The information relating to the amount of substance to be measured is corrected on the basis of the mean optical path length, such that the longer the mean optical path length, the greater the amount of substance to be measured is.

A fuel additive composition containing an alkylene-oxide-adducted hydrocarbyl amide and a friction modifier is disclosed. The alkylene-oxide-adducted hydrocarbyl amide and friction modifier are surprisingly useful for improving the acceleration response and the driving performance of vehicles having internal combustion engines when used as fuel additives in hydrocarbon-based fuels, such as gasoline fuel or diesel fuel.

Fuel additive composition and fuel composition containing the same

A fuel additive composition containing at least one amide compound selected from the group consisting of a fatty acid alkanol amide and a hydrocarbyl amide, a polyalkylene-oxide, and a friction modifier. The fuel additive composition is surprisingly useful for improving the acceleration response and the driving performance of vehicles having internal combustion engines when used as fuel additives in hydrocarbon-based fuels, such as gasoline fuel or diesel fuel.

A biodegradable multipurpose functional fluid for agricultural or construction machinery, comprising a base oil, a detergent-dispersant and an antioxidant (and a viscosity index improver if desired), in which the base oil is a fatty acid triester of trimethylolpropane obtained from a fatty acid that either has from 40% to 70% by weight of caprylic acid and from 20% to 50% by weight of capric acid, or is derived from a coconut oil which has been adjusted to have a stearic acid content of from 10% to 20% by weight.
