Mass composition of ultra-high-energy cosmic rays
The mass composition of ultra-high-energy cosmic rays describes which atomic nuclei arrive at Earth above 10^18 eV, inferred statistically from air showers since individual nuclei are destroyed in the atmosphere.
Mass concentration
Mass concentration is the mass of a constituent divided by the volume of the mixture, symbolized γ or ρ and measured in kilograms per cubic meter.
Mass concrete

Mass defect
The mass defect is the difference between an atomic nucleus's mass and the sum of its free protons and neutrons; it equals the nuclear binding energy.
Mass Democratic Movement
The Mass Democratic Movement was an informal coalition of anti-apartheid groups in South Africa in the late 1980s, formed after the United Democratic Front was banned in 1988.
Mass deworming
Mass deworming, or preventive chemotherapy, treats whole populations in worm-endemic areas without individual diagnosis. WHO recommends it for soil-transmitted helminths and schistosomiasis, though systematic reviews find little or no effect on most child welfare outcomes.
Mass diffusivity
Mass diffusivity, also called the diffusion coefficient, is the proportionality constant D in Fick's first law, with units of m²/s, that measures how fast a species spreads through a medium by random molecular motion.
Mass driver
A mass driver is an electromagnetic launcher for payloads, proposed by physicist Gerard K. O'Neill in 1974 and studied as a way to launch cargo from the Moon.
