A conductor or system of conductors for radiating and/or receiving radio energy. Also called aerial.

A state of resistance to corrosion or anodic dissolution of a metal caused by thermodynamic stability of the metal.

The direction to which a compass points. Magnetic north differs from true north because the magnetic fields of the planet are not exactly in line with the north and south poles. Observed differences between magnetic and true north is known as magnetic var ...

A bulkhead that will not let water pass from one side of it to the other.

Introducing nitrogen into the surface layer of a solid ferrous alloy by holding at a suitable temperature (below Ac1 for ferritic steels) in contact with a nitrogenous material, usually ammonia or molten cyanide of appropriate composition. Quenching is no ...

Charterers when cancelling agreement sometimes quote 'doctrine of frustration' i.e. vessel is lost, extensive delays.

Incapable of being mixed without separation phases. Water and petroleum oil are immiscible under most conditions, although they can be made miscible with the addition of an emulsifier.

Uncharted navigational danger that has been reported but has not been verified by survey.

An index calculated from total dissolved solids, calcium concentration, total alkalinity, pH and solution temperature that shows the tendency of a water solution to precipitate or dissolve calcium carbonate.

Transaction or interchange that occurs at the time a container leaves a rail or water terminal.

Capital gains tax arises as a result of a 'chargeable event' - in the case of stock market.

Amount paid to a shipowner for the carriage of cargo.

A registered trademark name for houses built with tires, aluminum cans, and earth.

The bridge used for taking observations, or directing the handling of the ship.

(1) A metal whose potential is highly positive relative to the hydrogen electrode. (2) A metal with marked resistance to chemical reaction, particularly to oxidation and to evolution by inorganic acids. The term as often used is synonymous with precious m ...

An air flow caused by a fan that draws air through the heat exchanger core in a uniform pattern to dissipate the sensible heat.

The effect of cooling by the radiation of heat from a building to the night sky.

This potential, sometimes called zeta potential, is a potential difference in the solution caused by residual, unbalanced charge distribution in the adjoining solution, producing a double layer. The electrokinetic potential is different from the electrode ...

Heating a ferrous alloy to a suitable temperature above the transformation range and then cooling in air to a temperature substantially below the transformation range.

Ventilation that is created by the differences in the distribution of air pressures around a building. Air moves from areas of high pressure to areas of low pressure with gravity and wind pressure affecting the airflow. The placement and control of doors ...
