Depictions of nudity
Depictions of nudity in art: the Western nude tradition from Greek athletes and Praxiteles' Knidian Aphrodite through medieval suppression, Renaissance revival, academy practice, feminist reclamation, and AI moderation bias.
Depleted uranium
Depleted uranium (DU), also known as Q-metal or Depletalloy, is uranium with its uranium-235 content reduced to about 0.2%, produced as a by-product of enrichment and used in tank armor and armor-piercing munitions.
Depletion (accounting)
Depletion is the allocation of a natural resource's cost, such as a mine or oil well, to the units extracted, allowing the owner to recover invested capital.
Depletion force
The depletion force is an attractive effective force between colloids when smaller, non-adsorbing solutes like polymers are expelled from the gap, proposed by Asakura and Oosawa in 1954.
Depletion region
A depletion region, also called a space charge region or depletion layer, is the zone at a semiconductor junction stripped of mobile carriers, forming the nonconducting core of every diode.
Deployable antenna reflector
A deployable antenna reflector is a large satellite antenna folded for launch and unfolded in orbit, most commonly a lightweight mesh reflector used on communications and radar spacecraft.
Deployment diagram
A deployment diagram is a UML structure diagram that shows which software artifacts run on which physical or virtual nodes, joined by communication paths, modeling a system's execution architecture.
Deployment environment
A deployment environment is an isolated runtime context where software runs, with its own configuration, data, credentials, and network, such as development, staging, or production.
Deployment frequency
Deployment frequency measures how often application changes are successfully deployed to production, typically per day, week, or month. It is one of DORA's four key delivery metrics.

Depolarization
Depolarization is the shift of a cell's membrane potential toward less negative values, mainly via cation influx. Key in action potentials (−70 mV to +30 mV), EPSPs, depolarizing GABA, and spreading depolarization in brain injury.
Depolarizing channel
The depolarizing channel is the standard symmetric noise model in quantum information theory, applying bit flips, phase flips, and combined flips with equal probability, analogous to the binary symmetric channel.
Depolymerization
Depolymerization, also called chemolysis, is a chemical recycling process that reverses polymerization, breaking polymers like PET and nylon-6 into monomers that can be repolymerized with no loss of properties.
