	CDF Electroweak Group : W Mass
		The rapidity distribution of the W and hence decay leptons are determined the parton distribution functions (PDFs).
		The W mass is determined from a fit to the W transverse mass distribution.
		The uncertainty in the W mass arising from uncertainties in the recoil model is 35 MeV which is principally due to the limited Z statistics from which the model is constrained.

	Molecular mass - Wikipedia, the free encyclopedia
		Due to this relativity, the molecular mass of a substance is commonly referred to as the relative molecular mass, and abbreviated to Mr.
		In mass spectrometry, the molecular mass of a small molecule is usually reported as the monoisotopic mass, that is, the mass of the most common isotope of each element.
		The molar mass of a substance is the mass of 1 mol (the SI unit for the basis SI quantity amount of substance, having the symbol n).

	Environmental Protection Agency > Basic Concepts in Environmental Sciences > Module 3: Size Distribution
		The median particle size (mass median particle diameter) is the particle diameter that divides the frequency distribution in half; fifty percent of the aerosol mass has particles with a larger diameter, and fifty percent of the aerosol mass has particles with a smaller diameter.
		The geometric mass mean diameter is equivalent to the mass median diameter for lognormal graphs due to the bell-shaped symmetrical curve produced.
		The geometric standard deviation of a lognormal distribution is determined by dividing the mass median particle diameter by the particle size at the 15.78 percent probability or by dividing the particle size at the 84.13 percent probability by the mass median particle diameter.

	Fundamental Nature of Relativistic Mass and Magnetic Field
		In the case of the proton, the mass of the electric field is accumulated until the proton mass is reached.
		Therefore, the fundamental phenomenon responsible for the increase of relativistic mass with velocity is the magnetic vortices of the electric field, as calculated with the Biot-Savart equation.
		Since it is observed that the mass of an electron, combined with the proton, gives the mass of the hydrogen atom (or the mass of the neutron), we must conclude that both the electron and the proton exist simultaneously in the hydrogen atom (and in the neutron).

	Water mass distribution and spreading
		In the following we present the large-scale distribution of the AAIW in the South Atlantic and discuss its sources and its circulation pattern.
		The resulting distribution of potential vorticity of the AAIW layer is shown in Fig.
		The rather homogeneous potential vorticity distribution in the gyre indicates that the recirculation dominates the spreading of the AAIW, whereas the influence of the water inputs from the Pacific and Indian Oceans is relatively small.

	Gravity and Mass Distribution inside Gravitational Objects
		Thinking over the second Newton's law (the force is directly proportional to acceleration and mass), we must come to the question what the reference frames or, what background are to be considered, in relation to which the acceleration of a respective accelerated mass object should be taken.
		Located far from the respective mass object, we will of course believe, that the best object to connect the reference frames system with it, will be some stable cosmic object (like a star), since it gives us chance to define exactly the object's trajectory (mathematical standpoint).
		In some cases (for instance inside gravitational fields) the motion of the mass objects cannot be detected if the reference frame will be connected with the cosmic objects, but it will have to be connected with the space.

	Molar mass distribution - Wikipedia, the free encyclopedia
		The Molar mass distribution in a polymer describes the relationship between a polymer fraction and the molar mass of that polymer fraction.
		The quantity a in the expression for the viscosity average molar mass varies from 0.5 to 0.8 and depends on the interaction between solvent and polymer in a dilute solution.
		The molar mass distribution of a polymer sample depends on factors such as chemical kinetics and work-up procedure.

		The mass of the upper legs for a 150 kg obese dummy would be 39.5 kg, compared to 31 kg for the 100 kg dummy.
		To determine the mass of the lower torso of the 100 kg dummy, we used the dimensions of the torso, the mass of the torso, and the location of the CoM of the torso given in the ISO standard.

	Hydrodynamic Size-Distribution Analysis
		A good approximation of a direct experiment for measuring the molar mass of a molecule is mass spectrometry (assuming only single charged ions), where we get very precise and very sharp peaks for each species, and size-distributions can (ideally) be observed simply as the envelope of all peaks.
		These are, for example, the apparent sedimentation coefficient distribution ls-g(s) (which for fundamental reasons is diffusionally broadened and therefore cannot have sharp peaks), and the study of broad distributions* of synthetic polymers (where we may know that the statistical nature of the synthesis leads to a quasi-continuous size-distribution without sharp peaks).
		These are explained in the help-pages of the c(s) distribution model, c(s) with prior knowledge, c(M) distribution model, and c(M) with prior knowledge.

	Divergence theorem - Wikipedia, the free encyclopedia (via CobWeb/3.1 planetlab2.cs.unc.edu) (Site not responding. Last check: 2007-10-14)
		In the case of a spherically symmetric mass distribution we can conclude from this that the field strength at a distance r from the center is inward with a magnitude of G/r² times the total mass at a smaller distance, regardless of any masses at a larger distance.
		In the case of an infinite cylindrically symmetric mass distribution we can conclude that the field strength at a distance r from the center is inward with a magnitude of 2G/r times the total mass per unit length at a smaller distance, regardless of any masses at a larger distance.
		More generally, for a mass distribution with the density depending on one Cartesian coordinate z only, gravity for any z is 2πG times the difference in mass per unit area on either side of this z value.

	The dust mass distribution of comet 81P/Wild 2
		The dust coma is characterized by “swarms” and “bursts” of particles with large variations of flux on small spatial scales, which may be explained by jets and fragmentation.
		The mass of the dust coma is dominated by larger particles, as was found for comets 1P/Halley and 26P/Grigg-Skjellerup.
		The mass distribution varies on small spatial scales with location in the coma, consistent with the jets and fragmentation inferred from the highly heterogeneous dust spatial distribution.
