The eikonal equation for neutron optics from the Schrödinger wave equation is derived in this section. In the eikonal equation, the rays of neutron optics are shown to be the trajectories of the particle neutrons with mass mn. That is, the eikonal equation links neutron wave optics to neutro...
The expressions for the two terms simplify into a ratio that provides the Reynolds number formula: Re=ρvdμ with each of the variables having the following meanings: Re is the Reynolds number, which is dimensionless. ρ is the fluid density, with dimensions of mass per volume. v is the ...

A novel ion funnel for focusing ions at elevated pressure using electrospray ionization mass spectrometry Rapid Communications in Mass Spectrometry, volume 11, issue 16, year 1997, pages 1813-1817 doi:10.1002/(SICI)1097-0231(19971030)11:16<1813::AID-RCM87>3.0.CO;2-D“ion funnel concept we ...
We have presented a derivation of macroscopic equations for plasmas and disparate mass binary mixtures from a consistent asymptotic analysis of the underlying kinetic equations, taking into account the smallness of the mass ratio between the particles simultaneously with letting the Knudsen number (ratio...
These limitations may be relaxed by using an optical grating with a larger number of grooves and the input of the larger beam size. Methods Experimental setup for the realization of the FSE Figure 5 shows the experimental setup built for the realization of the FSE. It is divided into four ...

Chemical equation balancer is a free online tool that helps you predict the product of a chemical reaction so that you can balance a chemical equation accurately.
(When mass equals that of the ground state, there is an explicit example, built using the pseudoconformal transformation, which shows that solutions can blow up in finite time.) In fact we can show a slightly stronger statement: for spherically symmetric focusing solutions with arbitrary mass, ...
