An enzyme complex, produced by fungi and bacteria, capable of decomposing cellulose into small fragments, primarily glucose.

A set of electrical conductors, often on a backplane, that carry data and power signals among the various components of a computer.

A spring line from the stern of a boat to mid ships to stop forward movement

The transparent or opaque sphere in an electric light that the electric light transmits through.

A type of inhibitor that appreciably changes the potential of u metal to a more noble (positive) value.

The part of the total carbon in steel or cast iron that is present as other than free carbon.

The potential energy available in a fuel as received, taking into account the energy loss in evaporating and superheating the water in the fuel. Equal to the higher heating value minus 1050W where W is the weight of the water formed from the hydrogen in t ...

The potential corresponding to the maximum active current density (critical anodic current density) of an electrode that exhibits active-passive corrosion behavior.

A thermometer which utilizes the thermal properties of gas. There are two forms of this instrument: (a) a type in which the gas is kept at constant volume, and pressure is the thermometric property, and (b) a type in which the gas is kept at constant pres ...

The mean wind speed over a specified period of time.

The heating capacity of a steam boiler; expressed in Btu per hour (Btu/h), or horsepower, or pounds of steam per hour.

A member of the ship's crew.

In navigation, the angle between the point at which the sun rises and sets and the true east and west points of the horizon.

Is the pressure existing at a given temperature in a closed vessel containing a liquid and the vapor from that liquid after equilibrium conditions have been reached. It is dependent only on temperature and must be determined experimentally.

Regulatory Evaluation

The older name for the Celsius temperature scale. Officially abandoned by international agreement in 1948, but still in common use.

The ratio of the electric current density to the electric field in a material. Also called electrical conductivity or specific conductance.

An instrument developed by K. Angstrom for measuring the effective terrestrial radiation. It consists of four manganin strips, of which two are blackened and two are polished. The blackened strips are allowed to radiate to the atmosphere while the polishe ...
