1) Anything composed of heterogeneous materials or elements.
From L. conglomeratus, p.p. of conglomerare "to roll together," from → com- "together" + glomerare "to gather into a ball," from glomus (genitive glomeris) "a ball," globus "globe;" PIE *gel- "to make into a ball."
1) The act of conglomerating; the state of being conglomerated.
Verbal noun of → conglomerate.
1) Rather large or great in size, distance, extent, etc.
The act or an instance of considering.
šetâb-e Coriolis (#)
Fr.: accélération de Coriolis
The apparent acceleration corresponding to the → Coriolis force. It is the acceleration which, when added to the acceleration of an object relative to a rotating → reference frame and to its → centrifugal acceleration, gives the acceleration of the object relative to a fixed reference frame. Coriolis acceleration equals 2ω x v, where ω is the → angular velocity of the rotating reference frame and v is the radial velocity of a particle relative to the center of the rotating reference frame.
corotating interaction region (CIR)
nâhiye-ye andaržireš-e hamcarxandé
Fr.: région d'interaction en corotation
A spiral-shaped density enhancement formed around a star when fast stellar winds collide with slower material. This large-scale wind structure can extend from the stellar surface to possibly several tens of stellar radii. The CIRs can be produced by intensity irregularities at the stellar surface, such as dark and bright spots, magnetic loops and fields, or non-radial pulsations. The surface intensity variations alter the radiative wind acceleration locally, which creates streams of faster and slower wind material. CIRs are responsible for the → discrete absorption components seen in some ultraviolet → resonance lines of → hot stars (S. R. Cranmer & S. P. Owocki, 1996, ApJ 462, 469).
Fr.: accélération cosmique
Fr.: interaction de Coulomb
1) General: The extent to which something is covered.
From → cover + -age a suffix forming abstract nouns.
Fr.: opérateur de création
An operator that acts on the → eigenstate describing the → harmonic oscillator to raise its → energy level by one step. The creation operator is the → Hermitian conjugate operator of the → annihilation operator.
damâ-ye Curie (#)
Fr.: température de Curie
The highest temperature for a given → ferromagnetic substance above which the → magnetization is lost and the substance becomes merely → paramagnetic. The Curie temperature of iron is about 1043 K and that of nickel 631 K.
Named after the French physicist Pierre Curie (1859-1906), a pioneer in magnetism, crystallography, and radioactivity. In 1903 he received the Nobel Prize in Physics with his wife Marie Curie (1867-1934, née Maria Skłodowska), and Henri Becquerel (1852-1908); → temperature.
Fr.: quadrilatère cyclique
A quadrilateral in which all four vertices lie on the circumference of a circle.
A second order, → partial differential operator in space-time, defined as: ▫2 = ∂2/∂x2 + ∂2/∂y2 + ∂2/∂z2 - (1/c2)∂2/∂t2, or ▫2 = ∇2 - (1/c2)(∂2/∂t2), where ∇2 is the → Laplacian and c is the → speed of light. This operator is the square of the → four-dimensional operator ▫, which is Lorentz invariant.
damâ-ye Debye (#)
Fr.: température de Debye
vâšetâbidan (#); vâšetâbândan (#)
(v.intr.) To slow down. (v.tr.) To decrease the velocity of.
The act or process of moving, or of causing to move, with decreasing speed. Sometimes called negative acceleration.
Verbal noun of decelerate.
Fr.: paramètre de décéleration
A parameter designating the rate at which the expansion of the Universe would slow down owing to the braking gravitational effect of the matter content of the Universe. It is expressed by: q(t) = -R(t)R ..(t)/R .2(t), where R(t) represents the size of the Universe at time t. See also → expansion parameter; compare with → acceleration parameter.
dowrân-e vâjafsari, ~ vâjofteš
Fr.: époque du découplage
1) General: Degenerate state or character. Reverting to an earlier, simpler, state.
From degener(ate), → degenerate, + -acy suffix of nouns of quality and state.
Vâgeni, from vâgen, → degenerate, + noun suffix -i.
fešâr-e vâgeni (#)
Fr.: pression de dégénérescence
Pressure in a degenerate electron or neutron gas. → degenerate matter.
