nuclear density

[′nü·klē·ər ′den·səd·ē]
(nuclear physics)
The mass per unit volume of a nucleus as a function of distance from the center of the nucleus, as determined by a number of different types of experiments which are in reasonably good agreement.

Unlike nuclear density gauges or radioactive alternatives, these innovative testing systems do not have any site hazards or requiring to close off work areas.
Some of the more common outdated references to ASTM standards involve soil classification, soil plasticity, Proctor compaction tests and the nuclear density gauge.
where [bar.[[sigma].sub.NN]] is the average energy dependent free space nucleon-nucleon (NN) cross section and it is taken from the average of [[sigma].sub.nn] and [[sigma].sub.np] x [[rho].sub.P] and [[rho].sub.T] are defined as the nuclear density of the projectile and target nuclei.
All checks will be conducted to ASTM International standards using a nuclear density gauge for rapid determination of the in-situ density and moisture content of soils and compacted materials.
1, is that light nuclei involving a [bar.K] as a constituent are shrunk to dense baryonic objects with densities nearly 3-times as much as the normal nuclear density. The structure of the most basic system, [K.sup.-]pp, first predicted in 2002, (2) was studied in detail by a realistic three-body calculation,6),7) and hence a molecular covalent nature of the strong binding was revealed.
The hole-hole contributions to the nucleon self-energy, which are included in the SCGF approach, yield a repulsive contribution the energy per nucleon, which increases with increasing nuclear density. This shifts the saturation point to a lower density and binding energy per nucleon so that also the saturation point obtained with SCGF is within the Coester band.
A study of 408 older women found that the geometric mean 5-year change in lens nuclear density was inversely associated with riboflavin intake.
According to Einstein, the theory works on densities up to the nuclear density. When one talks about a singular state of a cosmological solution, one means a so-called singular object.
Recent studies show that podocyte nuclear density ([N.sub.v]) and numbers of renal podocytes per glomerulus (N) are altered in experimental and spontaneous diabetes mellitus.
"Ultimately," explains Farrag, "we expect to gain regulator acceptance for alternative tools to the Nuclear Density Gauge for soil-compaction control.
In-place density is typically determined using the nuclear density gauge.
Many technicians, preoccupied with performing a nuclear density test or other quality assurance method, failed to hear or see approaching heavy construction vehicles and were run over.
