Definition: A device that combines a motor and a generator to convert alternating current into direct current.

Example: The engineer installed a dynamotor to ensure the system could efficiently convert power.

Definition: A type of vacuum tube that reduces the flow of electric current when the voltage is increased, often used in radio and electronic circuits.

Example: The engineer explained how the dynatron works in the radio transmitter.

Definition: A unit of force in the centimeter-gram-second system, defined as the force needed to accelerate a mass of one gram by one centimeter per second squared.

Example: The scientist measured the force in dynes to ensure accuracy in the experiment.

Definition: A type of enzyme that helps move cellular structures by breaking down ATP, particularly associated with microtubules.

Example: Dynein plays a crucial role in transporting organelles within the cell.

Definition: A soft, silvery element that is part of the rare-earth metals, used in various applications including nuclear research and in making strong magnets.

Example: Dysprosium is often used in the production of high-performance magnets for electric vehicles.

Definition: Relating to machinery or equipment that is used to move large amounts of soil or rubble, typically for construction or engineering projects.

Example: The earthmoving equipment was essential for the construction of the new highway.

Definition: A type of hard rubber that is often black and is used for electrical insulation due to its durability and resistance to heat.

Example: The electrician used ebonite to insulate the wires in the circuit.

Definition: To make something black in color, similar to the dark wood of ebony.

Example: The artist decided to ebonize the furniture to give it a more elegant look.

Definition: A type of hormone found in insects and crustaceans that helps them grow and change their skin during molting.

Example: Ecdysone plays a crucial role in the molting process of insects.

Definition: The successful process of a plant or animal species settling and growing in a new environment.

Example: The ecesis of the new plant species in the area was a positive sign for the ecosystem.
