The entropy is a derivation of the free energy of the system, and the latter is the product of the

Boltzmann constant, the temperature and the configuration partition function.

Among the topics are frequency instability, accurate radiometry from space as an essential tool for climate studies, metrological traceability in ionizing radiation measurements for radiotherapy and radiation protection, temperature metrology and the

Boltzmann constant, and microwave clocks and fountains.

This contribution may be interpreted as quantum pressure term with [[??].sup.2.sub.Fs] = 2[k.sub.B][T.sub.F]/[m.sub.s] being the Fermi speed, [k.sub.B] is the

Boltzmann constant, and [T.sub.F] is Fermi temperature of carriers.

The first step in the derivation is to discretize the microscopic velocity space c = [c.sub.T]v, where v is a dimensionless velocity, [c.sub.T] = [square root of [k.sub.b][T.sub.0]/m] the thermal reference velocity, [k.sub.b] the

Boltzmann constant, m the molecular mass of the fluid, and [T.sub.0] a reference temperature.

where [n.sub.0] denotes the average number of positive or negative ions in the buffer, z is the valance, e is the electron charge, T is the absolute temperature, [psi] is the electric potential, and [k.sub.B] is the

Boltzmann constant. Let [[phi].sup.*] = [psi]/[xi] be the normalized electroosmotic potential in which % is the zeta potential and let [alpha] = (ez[xi]/[k.sub.B])T be a parameter; then we have

In which: q--electron charge; T--the absolute temperature of solar cell; k--the

Boltzmann constant; A--diode curve factor; [I.sub.0]--reverse saturation current; [I.sub.sc]--short circuit current; U--equivalent diode voltage;

Scientists at the National Physical Laboratory (NPL) have performed the most accurate measurement yet of the

Boltzmann constant, which states how much energy at the individual particle level corresponds to each degree of temperature.

where [theta] = [Q.sub.e]/MK[upsilon], [Q.sub.e]--charge of electron 1.59 x [10.sup.-19] [C]; M --idealist or emission factor (typically varies from 1.02 to 1.6); K -

Boltzmann constant 1.38 x [10.sup.-23] [J/K]; [theta] - PN junction temperature [K]; [I.sub.s]__saturation current in reverse direction and [u.sub.D]--voltage of diode.

The app includes a glossary of more than 300 technical corrosion engineering terms, a list of constants, such as the

Boltzmann constant, reference electrodes and schematics.

where [E.sub.u] and [E.sub.l] are the upper and lower energy of the levels involved in the transition, [k.sub.B] is the

Boltzmann constant, h the Planck constant, [c.sub.0] the velocity of light in vacuum, [[lambda].sub.0] the center wavelength of the transition, [L.sub.max] the radiance of the self-reversal maximum.

respectively, where n is the mobile ion concentration, q is the charge of an ion, D is the diffusion constant of the ion, L is the thickness of the cells, [[epsilon].sub.0] is the permittivity in free space, [k.sub.B] is the

Boltzmann constant, T is the absolute temperature, and [[epsilon]'.sub.b] is the intrinsic dielectric constant of the NLC bulk.
