Subsequently, we learned from Douglass that his sample contained a few percent Af impurity.

We found no obvious effects due to preferred orientation of the crystallites in this sample nor would we expect to on the basis of the shape found from electron microscopic examination.

Spectra were obtained from a powdered sample having the shape of a right circular cylinder with a height-to-diameter ratio of 4::

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.

Spectra were also obtained from a third sample of Af which had been diluted to three times its original volume with powdered, anhydrous alundum ( Af ).

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.

For purposes of sample selection only ( individual tests were given later ) we obtained group test scores of reading achievement and intelligence from school records of the entire third-grade population in each school system.

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

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.

A test result ( calculated from the null hypothesis and the sample ) is called statistically significant if it is deemed unlikely to have occurred, assuming the truth of the null hypothesis.

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.

A formula for calculating an unbiased estimate of the population variance from a finite sample of n observations is:

Consider the sample ( 4, 7, 13, 16 ) from an infinite population.

In the Restoration and eighteenth century, poetry written in couplets is sometimes varied by the introduction of a triplet in which the third line is an alexandrine, as in this sample from Dryden, which introduces a 6-5-6 triplet after two pentameter couplets:

This conditioning process is responsible that only about 5 % of the aspirated sample solution reaches the flame, but it also guarantees a relatively high freedom from interference.

* Atomization of the sample from a graphite platform inserted into the graphite tube ( L ’ vov platform ) instead of from the tube wall in order to delay atomization until the gas phase in the atomizer has reached a stable temperature ;

These spectra are then multiplied with a factor to match the intensity of the sample spectrum and subtracted pixel by pixel and spectrum by spectrum from the sample spectrum using a least-squares algorithm.

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

Technically, the method is destructive in nature removing ions from a sample surface in order to image and identify them, generating magnifications sufficient to observe individual atoms as they are removed from the sample surface.

He recalled trying out for Prince Valiant, saying he provided a sample " when creator Hal Foster decided to go into semi-retirement.

It was done as a sample when Foster interviewed and a couple of others ( Wally Wood and John Cullen Murphy ) to take over.

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.

The relatively low concordance between dizygotic twins brought up together suggests that shared family environmental effects are limited, although the ability to detect them has been limited by small sample sizes.

On November 1, 2005, Germany enacted the “ Act on Model Case Proceedings in Disputes under Capital Markets Law ( Capital Markets Model Case Act )” allowing sample proceedings to be brought before the courts in litigation arising from mass capital markets transactions.

First, a voltage bias is applied and the tip is brought close to the sample by some coarse sample-to-tip control, which is turned off when the tip and sample are sufficiently close.

First, the sample is brought to the desired test temperature under an inert atmosphere, usually nitrogen.

The possibility of fabrication was first brought to the attention of the scientific community when Kamin noticed that Burt's correlation coefficients of monozygotic and dizygotic twins ' IQ scores were the same to three decimal places, across articles – even when new data were twice added to the sample of twins.

A soil sample from Mare Crisium was successfully brought to Earth on 22 August 1976 by the Soviet lunar mission Luna 24.

He had brought vines from the Cape of Good Hope, found a species resistant to blight, took a sample of his wine to London in 1822 and won a silver medal for it.

When the tip is brought into proximity of a sample surface, forces between the tip and the sample lead to a deflection of the cantilever according to Hooke's law.

Shortly thereafter, the meteorite now called Allan Hills 81005 was sent to Washington, DC, where Smithsonian Institution geochemist Brian Mason recognized that the sample was unlike any other known meteorite and resembled some rocks brought back from the Moon by the Apollo program.

Cushing brought back a sample of Riva-Rocci's sphygmomanometer, and blood pressure measurement became a vital sign and its use spread like wildfire across the US and western world as a direct contribution by Harvey Cushing.

In open cup devices the sample is contained in an open cup which is heated, and at intervals a flame is brought over the surface.

The sample is located, then the record is brought about an inch or two backwards from the beginning of the sample.

Also, sample material does not have to be brought into contact with the instrument — preventing possible cross contamination.

It also brought the group to the attention of the rave community due to the track " Mr Kirk's Nightmare ", which pivoted around the " Get Into Something " break ( taken from the Isley Brothers ) and a morbid vocal sample (" Mr Kirk?

It was previously believed that the strongest organic concentrations it measured were minute trace contaminants brought from Earth, left over from the assembly and cleaning of the sample chambers and instruments.

In addition to sensor-based measurements above, robotic equipment can sample formation fluids which may then be brought to the surface for laboratory examination.

Recent developments, including publishing of a controversial documentary film about alleged frauds in the ballot counting during the election, brought on December 2006 the Electoral Committee of the Italian Chamber of Deputies to request for a recount of all ballot papers, starting from a 10 % sample.

Near the bottom here, I found what I think to be a few small pieces of burned wood or charcoal, also some dark unctuous sort of earth, a sample of both I brought away.

The night before the World Congress, Dutch newspaper, Het Parool wrote, “ Yesterday, the world champion Fred Kaps from Rotterdam gave an example of the act he will use to defend his title .” The paper went on to say that when Kaps gave a sample performance for his colleagues, it “… nearly brought the house down .”

A test sample brought back to Fort Collins tested nearly 800 USD per ton.
