Actinometers are instruments used to measure the heating power of radiation.
In chemistry and physics, activation energy is the minimum amount of energy that must be provided to compounds to result in a chemical reaction.
Activation products are materials made radioactive by neutron activation.
The length of the U-bend in the borehole below the header trench (usually 4 to 6 feet less than the total borehole length from the surface).
Offshore cranes and other equipment doing subsea work are provided with AHC systems to ensure presicion in high sea states and extreme weather conditions. The essential function of AHC technology...
Solar hot water systems use pumps or fans to circulate fluid (often a mixture of water and glycol to prevent freezing during winter periods) or air, through solar collectors, and are therefore classified under active solar technology.
An active stall system reads the power output the way a pitch-controlled system does, but instead of pitching the blades out of alignment with the wind, it pitches them to produce stall.
The reduction of rolling provides better fuel/speed performance on rough seas, enhances crew safety and possibly their efficiency. The roll amplitude can be reduced by passive devices, such as bilge keels, or by active devices...
An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve.
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation, in a short period of time.
Registered trademark for AUS32 (Aqueous Urea Solution 32.5%) and is used in a process called selective catalytic reduction (SCR) to reduce emissions of oxides of nitrogen from the exhaust of diesel engine motor vehicles.
The mass of water which is considered to be set in motion by a ship when heaving, pitching, rolling and vibrating.
Chemicals added to fuel, lubricating oils or fresh water to improve their physical or chemical characteristics.
Bonding strength; the attraction of a coating to the substrate, or to another film of paint or any other material such as steel.
Substance that makes things stick.
A thermodynamic process described by that no heat is added or removed from the system.
In thermodynamics, an adiabatic process is a type of thermodynamic process which occurs without transferring heat or mass between the system and its surroundings.
A feature allowing the user to adjust the setpoint of a variable that will invoke an action on another variable.
The confirmed or official ship dimensions.
As used in international conventions, the government of the state whose flag the ship is flying.
