The plasma parameter is a dimensionless number, denoted by capital Lambda, Λ.The plasma parameter is usually interpreted to be the argument of the Coulomb logarithm, which is the ratio of the maximum impact parameter to the classical distance of closest approach in Coulomb scattering.
The Flory–Fox equation relates the number-average molecular weight, M n, to the glass transition temperature, T g, as shown below: =, where T g,∞ is the maximum glass transition temperature that can be achieved at a theoretical infinite molecular weight and K is an empirical parameter that is related to the free volume present in the polymer sample.
The Planck relation [1] [2] [3] (referred to as Planck's energy–frequency relation, [4] the Planck–Einstein relation, [5] Planck equation, [6] and Planck formula, [7] though the latter might also refer to Planck's law [8] [9]) is a fundamental equation in quantum mechanics which states that the energy E of a photon, known as photon energy, is proportional to its frequency ν: =.
Quantity calculation with the Bateman-Function for plutonium-241 While the Bateman formula can be implemented in a computer code, if λ j ≈ λ i {\displaystyle \lambda _{j}\approx \lambda _{i}} for some isotope pair, catastrophic cancellation can lead to computational errors.
In calculation, the effects of r o are negligible, [1] so the equation is typically expressed as: λ = r m r i {\displaystyle \lambda ={\sqrt {\frac {r_{m}}{r_{i}}}}} The membrane resistance is a function of the number of open ion channels , and the axial resistance is generally a function of the diameter of the axon .
The Scherrer equation, in X-ray diffraction and crystallography, is a formula that relates the size of sub-micrometre crystallites in a solid to the broadening of a peak in a diffraction pattern.
President Donald Trump has issued a slew of executive orders (EO) since beginning his second term, including one that may have an impact on your tax refund.One of Trump’s EOs initiated a hiring ...
The inelastic mean free path (IMFP) is an index of how far an electron on average travels through a solid before losing energy.. Universal curve for the electron inelastic mean free path in elements based on equation (5) in. [1]
