The K factor, a term used to denote the rate of heat transmission through a material ( B.t.u./sq. ft. of material/hr./*0F./in. of thickness ) ranges from 0.24 to 0.28 for flexible urethane foams and from 0.12 to 0.16 for rigid urethane foams, depending upon the formulation, density, cell size, and nature of blowing agents used.

Table 1,, p. 394, shows a comparison of K factor ratings of a number of commercial insulating materials in common use, including two different types of rigid urethane foam.

where R is the rainfall erosivity factor, K is the soil erodibility factor, L and S are topographic factors representing length and slope, and C and P are cropping management factors.

In order to get agreement with experimental results, Fresnel found that the individual contributions from the secondary waves on the sphere had to be multiplied by a constant, i / λ, and by an additional inclination factor, K ( χ ).

K. Fulford, A. Smirnov, and E. Snow state: " An important vulnerability factor, therefore, for the abuse of psychiatry, is the subjective nature of the observations on which psychiatric diagnosis currently depends.

K-factor or K factor may refer to:

* K factor ( crude oil refining )

The noise factor is defined as the ratio of the output noise power of a device to the portion thereof attributable to thermal noise in the input termination at standard noise temperature ( usually 290 K ).

where Y is total output, K is the stock of capital in the economy, L is the labor force ( or population ) and A is a " catch all " factor for technology, role of institutions and other relevant forces which measures how productively capital and labor are used in production.

Here G is final average grain size, G < sub > 0 </ sub > is the initial average grain size, t is time, m is a factor between 2 and 4, and K is a factor given by:

Here Q is the molar activation energy, R is the ideal gas constant, T is absolute temperature, and K < sub > 0 </ sub > is a material dependent factor.

with t the day of calculation ; N the number of constituent shares in the index ( usually 40 ); Q < sub > i, t </ sub > the number of shares of company i on day t ; F < sub > i, t </ sub > the free float factor of share i ; f < sub > i, t </ sub > the capping factor of share i ( exactly 1 for all companies not subject to the 15 % cap ); C < sub > i, t </ sub > the price of share i on day t ; Q < sub > i, 0 </ sub > the number of shares of company i on the index base date ; C < sub > i, 0 </ sub > the price of equity i on the index base date ; and K < sub > t </ sub > the " adjustment coefficient for base capitalization " on day t ( reflecting the switch from the French franc to the Euro in 1999 ).

* K factor crude oil refining

This is the present value factor for K.

* Vitamin K is an essential factor to a hepatic gamma-glutamyl carboxylase that adds a carboxyl group to glutamic acid residues on factors II, VII, IX and X, as well as Protein S, Protein C and Protein Z.

Deficiency of Vitamin K may also contribute to bleeding disorders because clotting factor maturation depends on Vitamin K.

They are set on a so-called " K factor " which determines the average value of price rises above the current rate of inflation ( RPI ) for the next five years.

Woodward's dissertation director was Howard K. Beale, a Reconstruction specialist who promoted the Beardian economic interpretation of history that deemphasized ideology and ideas and stressed material self-interest as a motivating factor.

Sometimes the factor charges the seller ( the factor's " client ") both a discount fee, for the factor's assumption of credit risk and other services provided, as well as interest on the factor's advance, based on how long the advance, often treated as a loan ( repaid by set-off against the factor's purchase obligation, when the account is collected ), is outstanding .< Ref Name =" CPA "> J. G. Siegel, N. Dauber & J. K. Shim, " The Vest Pocket CPA ", Wiley, 2005 .</ ref > The factor also estimates the amount that may not be collected due to non-payment, and makes accommodation for this in pricing, when determining the purchase price to be paid to the seller.

Roundabouts, in their modern form, were standardised in the U. K., improving on the experience of traffic circles built in the U. S. following WWII, Modern roundabouts are now common in many countries around the world.

It was A. K Erlang ( 1878-1929 ) who first conceived of a queue as a solution to congestion in telephone traffic.
