Any machine capable of producing power to do work. An electric or hydraulic motor, steam engine or similar drive, acting directly on the deck machinery. Note—In a diesel electric motor is the prime mover.

A sailor's carving or etching on bones, teeth, tusks or shells.

Same as ombrometer.

The notification to a client by a brokerage house that more funds are required to bring a margin.

The energy lost from the movement of a fluid in a conduit (pipe) due to the disturbances created by the contact of the moving fluid with the surfaces of the conduit, or the additional pressure that a pump must provide to overcome the resistance to fluid f ...

A contract for leasing between the ship owners and the lessee. It would state, e.g., the duration of the lease in years or voyages.

When an electrode reaches dynamic equilibrium in a solution, the rate of anodic dissolution balances the rate of cathodic plating. The rate at which either positive or negative charges are entering or leaving the surface at this point is known as the exch ...

A plot of the redox potential of a corroding system versus the pH of the system, compiled using thermodynamic data and the Nernst equation. The diagram shows regions within which the metal itself or some of its compounds are stable.

Solar and terrestrial radiation directed downwards (towards the earth's surface); incoming radiation.

Wind with a speed between 17 and 21 knots (19 and 24 mph); Beaufort scale number 5.

The shear stress on a transverse cross section resulting from u twisting action.

An instrument for measuring the frost point of the atmosphere.

A hypothetical body which absorbs some constant fraction, between zero and one, of all electromagnetic radiation incident upon it, which fraction is the absorptivity and is independent of wavelength. Compare to black body, white body.

A standard interface between a computer input/output port and a peripheral device. Signal properties including time duration, voltage. and current, are specified by the Electronic Industries Association.

A measure of a fuel's (liquid) ease of self-ignition.

The ratio of chemical substances necessary for a reaction to occur completely.

The situation which exists when a person dies without making a will. The person is then said to have.

The reversible potential for an electrode process when all products and reactions are at unit activity on a scale in which the potential for the standard hydrogen half-cell is zero.

Thermometer used for measuring the lowest temperature attained during a given interval of time, for example, a day.
