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 ( 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 ).

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.

While the choice of air may seem arbitrary, he based his conclusion on naturally observable phenomena in the process of rarefaction and condensation .< ref > Guthrie, W. K. C.

Samples may be required to be cooled anywhere between room temperature to as low as 15 K.

* SO — Strikeout Also may be notated as " K ".

The only bird group known for certain to have survived the K – T boundary is the Neornithines ( though one Paleogene species, Qinornis paleocenica, may represent a surviving non-neornithine bird ).

The most recent evidence shows that the traps erupted over 800, 000 years spanning the K – T boundary, and therefore may be responsible for the extinction and the delayed biotic recovery thereafter.

:: The RBE may be defined as K < sub > x </ sub > 3

Scholars have often speculated that Hamlet < nowiki ></ nowiki >' s Polonius might have been inspired by William Cecil ( Lord Burghley )— Lord High Treasurer and chief counsellor to Queen Elizabeth I. E. K. Chambers suggested Polonius's advice to Laertes may have echoed Burghley's to his son Robert Cecil.

More typically the bottom is now heavier than the top ( but in some cases like the K Zildjian Steve Gadd Session Hats the pattern is reversed for a cleaner chick and cleaner sticking ), and may also be vented, this being one innovation to have caught on.

Channels differ with respect to the ion they let pass ( for example, Na < sup >+</ sup >, K < sup >+</ sup >, Cl < sup >−</ sup >), the ways in which they may be regulated, the number of subunits of which they are composed and other aspects of structure.

K cell ( s ) may refer to:

Geographer K. E. Barber has argued against this hypothesis, saying that pools at Lindow Moss would have been too shallow, and suggests that the peat may have been peeled back to allow the burial and then replaced, leaving the stratigraphy apparently undisturbed.

The upper ( Cretaceous ) boundary is set at the Cretaceous-Tertiary ( KT ) extinction event ( now more accurately called the Cretaceous – Paleogene ( or K – Pg ) extinction event ), which may have been caused by the impactor that created Chicxulub Crater on the Yucatán Peninsula.

Some are produced by the human body with adequate precursors ( glutathione, Vitamin C ), and those the body cannot produce may only be obtained in the diet via direct sources ( Vitamin C in humans, Vitamin A, Vitamin K ) or produced by the body from other compounds ( Beta-carotene converted to Vitamin A by the body, Vitamin D synthesized from cholesterol by sunlight ).

Those with an otherwise adequate calcium intake can develop osteoporosis due to the inability to absorb calcium and / or vitamin D. Other micronutrients such as vitamin K or vitamin B < sub > 12 </ sub > deficiency may also contribute.

It is important to note that the actual nut hand may not be the same as the absolute nut hand ; for example, if the board is < font color = red > 7 ♥</ font > 2 ♣ K ♠ < font color = red > K ♥ 3 ♦</ font > a player with K ♣ < font color = red > K ♦</ font > has the absolute nut hand.

If Carol has a hand like < font color = red > K ♥</ font > J ♠, she may choose to fold.

We may calculate the ratio of the populations of the two states at room temperature ( T ≈ 300 K ) for an energy difference ΔE that corresponds to light of a frequency corresponding to visible light ( ν ≈ 5 × 10 < sup > 14 </ sup > Hz ).

Many words spelled with E were changed to Ä ( elf-älf, hjerta-hjärta, jern-järn ), and under Q it was stated that Q may at will be replaced with K. By a government resolution on November 16, 1889, the spelling used in this edition of SAOL was to be used for teaching in Swedish highschools ( allmänna läroverk ) and teacher colleges ( seminarier ).

According to informal tradition, O stars are called " blue ", B " blue-white ", A stars " white ", F stars " yellow-white ", G stars " yellow ", K stars " orange ", and M stars " red ", even though the actual star colors perceived by an observer may deviate from these colors depending on visual conditions and individual stars observed.

The English Roman Catholic writer G. K. Chesterton said of More that " He may come to be counted the greatest Englishman, or at least the greatest historical character in English history.

It has been reported that MK7 may be converted from phylloquinone ( K < sub > 1 </ sub >) in the colon by E-coli bacteria.

In 2002 it was found that to get maximum carboxylation of osteocalcin, one may have to take up to 1000 μg of vitamin K < sub > 1 </ sub >.
