The Bureau is pursuing an active program to provide a temperature scale and thermometer calibration services in the range 1.5 to 20 Af.

Several germanium resistors have been thermally cycled from 300 to 4.2 Af and their resistances have been found to be reproducible within 1/3 millidegree when temperatures were derived from a vapor pressure thermometer whose tubing is jacketed through most of the liquid helium.

A study of the hydrogen line profiles indicates that a measurement of these profiles can be used to calculate a temperature for the arc plasma that is reliable to about Af percent.

The lower number is always divided into the upper number: Af

The formula is: Af.

Cylinder volume is determined in exactly the same manner as for the displacement formula: Af.

The formula for this step is: Af.

To determine car speed for a given combination of engine speed, gear ratio, and tire size, the formula is: Af.

To determine engine speed for a given combination of the other three factors the formula is: Af.

To determine the rear axle gear ratio for a combination of the other three factors, the formula is: Af.

Presently, the 742C is available in Af.

Note: If 1/2-inch panel board is used inside and out, or 5/8-inch one side and 3/8-inch the other, and 1/8-inch glass is used, stock lumber in Af, Af, and Af can be used in making the glass panels.

There is no better way to waste time than trying to install a furnace in a finished Af closet.

The result of the observations is Af where the phase angle, Q, is measured in degrees from new moon and the probable errors include absolute as well as relative errors.

In free-burning electric arcs, for instance, approximately 90% of the total arc power is transferred to the anode giving rise to local heat fluxes in excess of Af as measured by the authors -- the exact value depending on the arc atmosphere.

The heat transfer to the anode in free burning arcs is enhanced by a hot gas jet flowing from the cathode towards the anode with velocities up Af.

The mean temperature of the surface was then computed according to the following relation: Af where x is the fraction of the plug area covered by the hot spot.

The total heat flux from the porous plug into the plug holder is thereby Af.

The radiation loss from the anode surface was computed according to Af where Af is the mean of the fourth powers of the temperatures Af and Af calculated analogously to equation ( 1 ).

This means that work equals Q which in turn equals Af.

The threshold mass is derived from the momentum threshold with the assumption of a mean impact velocity of Af in the U.S. work and Af in the U.S.S.R. work.

The word `` binomial '' means `` of two names '' or `` of two terms '', and both usages apply in our work: the first to the names of the two outcomes of a binomial trial, and the second to the terms P and Af that represent the probabilities of `` success '' and `` failure ''.

To avoid this contradiction it is necessary that C be composite, with the secant of **zg and a curve of order Af as components.

When it is necessary to be specific we say that the optimal policy is an optimal R-stage policy with respect to the feed state Af.

The mixture was then extracted with alkali and with water following which the carbon tetrachloride was distilled on a Vigreux column, a 25% center cut being retained which was then degassed under vacuum in the presence of Af.

After dialysis the sample was centrifuged and the supernatant placed on a Af cm column of EEAE-cellulose equilibrated with starting buffer.

( 4 ) The conjugates were passed through a diethylaminoethyl ( DEAE ) cellulose column equilibrated with neutral phosphate buffer ( PBS ) containing Af potassium phosphate and Af.

When 1 ml of conjugate was passed through a column ( Af ), the first and second milliliter fractions collected were the most specific and gave no nonspecific staining in some experiments, and very little in others.

Nonspecific staining could be satisfactorily eliminated by passing these conjugates through a DEAE-cellulose column as described for Af.

When now we count the frequency of the 71 items in the two language families appearing in the same column or grade, or one column or grade apart, or two or three or four, we find these differences: Af

To extract the optimal R-stage policy with respect to the feed state Af, we enter section R of this table at the state Af and find immediately from the last column the maximum value of the objective function.

Preliminary calibrations of the resistors have been made from 4.21 to 2.16 Af at every 0.1 Af.

The reproducibilities of helium vapor-pressure thermometers have been investigated in conjunction with a `` constant temperature '' liquid helium bath from 4.2 to 1.8 Af.

Over a temperature range from 25 to 200 Af and at pressures up to 250 atm, an overload of 300 psi, applied for a period of one day, results in an uncertainty in the pressure of, at most, one millimeter of mercury.

The results of the study, based on collision integrals computed from the latest critically evaluated data on intermolecular forces in air, will be reported in the form of a table of viscosity, thermal conductivity, thermal diffusion, and diffusion coefficients at temperatures of 1,000 to 10,000 Af and of logarithm of pressure in atmospheres from Af to Af times normal density.

All the bars are cut from Af brass.

For example, for the problem Af, 10 from 25 equals 15, then 6 from 15 equals 9.

Using the figures from the previous examples, the equation becomes: Af.

( Made from modern wooden molds Af.

The wall panels are constructed of a framework of standard Af and Af of a good grade, free from structural faults.

The filler panels for the gable ends are cut from full Af sheets as shown, leaving no wastage.

It was calculated from the temperature gradient Af at Af inch as Af.
