So it was that when Mr. Brown and Mr. Sharpe first saw the French tool on exhibition in Paris in 1868, they brought a sample with them to the United States and started Brown & Sharpe in yet another field where it retains its leadership to this day.

By this method it was determined that the normal pressure exerted by a sample of polybutene ( molecular weight reported to be 770 ) was over half an atmosphere.

For the low-temperature measurements the sample was cooled by a cold nitrogen gas flow method similar to that of Andrew and Eades.

One sample, which had been exposed to the atmosphere after evacuation at 375-degrees-C, showed the presence of adsorbed water ( about 0.3 wt ) ) as evidenced by a weak resonance line which was very narrow at room temperature and which disappeared, due to broadening, at low temperature.

The top of the sample was nearly flat and the bottom hemispherical.

Spectra were also obtained from a sample in a spherical container which was made by blowing a bubble on the end of a capillary glass tube.

The bubble was filled to the top and special precautions were taken to prevent any sample from remaining in the capillary.

This sample was contained in a cylindrical container similar to that described above.

Direct proportionality of the rate to the incident intensity has also been assumed in obtaining the value in the last column for the fourth sample of series 2, where the light intensity was reduced by use of a screen.

One drop of each sample was added to one drop of a 2% suspension of group Af or group B red cells in a small Af test tube.

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

When paper electrophoresis was to be used for preparation, eight strips of a whole serum sample or a chromatographic fraction concentrated by negative pressure dialysis were run/chamber under the conditions described above.

A sample of Fraction Af from group O plasma was dissolved in starting buffer, dialyzed against this buffer and subjected to chromatography using the gradient shown in Fig. 2.

when the insoluble fraction was suspended in a volume of saline equal to that of the original serum sample, no complete antibody activity could be detected.

The final sample was not significantly different from a normal distribution in regard to reading achievement or intelligence test scores.

An interview schedule of open-ended questions and a multiple-choice questionnaire were prepared, and one parent of each of the sample children was seen in the home.

The Wechsler Intelligence Scale For Children was administered to each sample third-grade child by a clinical worker.

It was compiled as a control sample to determine if the opinions and practices of companies on the lists submitted by the members of the Aerospace Industries Association were materially different from those of other small firms selling to defense programs.

The control sample was selected by taking the bottom name of each of the two columns of names on each page of the alphabetical listing of manufacturers in the Thomas Register.

It was concluded that it would be appropriate to process the two groups of responses as a single sample of all small businesses engaged in, or wishing to sell to, defense programs.

Argon ( αργος, Greek meaning " inactive ", in reference to its chemical inactivity ) was suspected to be present in air by Henry Cavendish in 1785 but was not isolated until 1894 by Lord Rayleigh and Sir William Ramsay in Scotland in an experiment in which they removed all of the oxygen, carbon dioxide, water and nitrogen from a sample of clean air.

Generally, above 15 % amaranth grain flour, there were significant differences in the evaluated sensory qualities and the high amaranth-containing product was found to be of unacceptable palatability to the population sample that evaluated the baked products.

Accordingly, highest priority was given to a highlands site that would allow the astronauts to sample material older than the impact that formed the Imbrium basin.

The general theory of resonance shifts is used to derive a general expression for the second moment Af of a polycrystalline paramagnetic sample and is specialized to Af.

Homozygous and heterozygous Af cells, Af and homozygous and heterozygous Af cells were used to test each sample ; ;

Therefore, it is recommended that in such cases the sample be replaced, or if used, the results of dimensional change or dimensional restorability tests be considered as indicative only.

* Boolean analysis – a method to find deterministic dependencies between variables in a sample, mostly used in exploratory data analysis

* Principal component analysis – transformation of a sample of correlated variables into uncorrelated variables ( called principal components ), mostly used in exploratory data analysis

A common example used in undergraduate education is the determination of the amount of water in a hydrate by heating the sample to remove the water such that the difference in weight is due to the loss of water.

If the amount in the sample is below an instrument's range of measurement, the method of addition can be used.

The method of standard addition is used in instrumental analysis to determine concentration of a substance ( analyte ) in an unknown sample by comparison to a set of samples of known concentration, similar to using a calibration curve.

In analytical chemistry the technique is used for determining the concentration of a particular element ( the analyte ) in a sample to be analyzed.

Hardware from other vendors often used sample rates as high as 8192 Hz, often integer factors of video clock signals.

* whiff rate: a term, usually used in reference to pitchers, that divides the number of pitches swung at and missed by the total number of swings in a given sample.

* Analytical chromatography is used to determine the existence and possibly also the concentration of analyte ( s ) in a sample.

This motion causes the column to see one partitioning step per revolution and components of the sample separate in the column due to their partitioning coefficient between the two immiscible liquid phases used.

If are independent and identically distributed random variables, each with a standard Cauchy distribution, then the sample mean has the same standard Cauchy distribution ( the sample median, which is not affected by extreme values, can be used as a measure of central tendency ).

However, because of the fat tails of the Cauchy distribution, the efficiency of the estimator decreases if more than 24 % of the sample is used.

When a sample consists of more than one variable, descriptive statistics may be used to describe the relationship between pairs of variables.

* In rotary evaporation a vacuum distillation apparatus is used to remove bulk solvents from a sample.

The term " total DDT " is often used to refer to the sum of all DDT related compounds ( p, p '- DDT, o, p '- DDT, DDE, and DDD ) in a sample.

Filters can be represented by block diagrams, which can then be used to derive a sample processing algorithm to implement the filter with hardware instructions.

A subclass of this is focused ion beam milling, where gallium ions are used to produce an electron transparent membrane in a specific region of the sample, for example through a device within a microprocessor.

In another study, data from a sample of white, Christian men and women were used to test the hypothesis that traditional, church-centered religiousness and de-institutionalized spiritual seeking are distinct ways of approaching fear of death in old age.

This is the use of the factor n-1 in the denominator of the formula, rather than just n. This occurs when the sample mean rather than the population mean is used to centre the data and since the sample mean is a linear combination of the data the residual to the sample mean overcounts the number of degrees of freedom by the number of constraint equations — in this case one.
