Sentence examples for samples of elements from inspiring English sources

More recently, precision mass-spectrometric methods have been used to determine the distribution and weights of isotopes in various naturally occurring samples of elements.

Since there were mixtures of isotopes of different atomic weights in samples of elements found in nature, the International Union of Pure and Applied Chemistry (IUPAC) began publishing atomic weights with uncertainties.

Find a resource that sells samples of elements at a decent price, or get the materials to make your own.

For a sample of elements, it is necessary to calculate the median exactly times.

This yields a new sample of elements, and their median (the outer median) gives the final estimate S. A beneficial property of the S-estimate is that it does not rely on a calculation of the location estimate, and consequently it produces an accurate estimate of variance for nonsymmetric sample distributions, that is, the image regions containing edges.

This is a confirmation of the 'scalable' character of gene expression network that constitutes a strongly connected set whose general connectivity can be appreciated starting from a minimum sample of elements.

The amount of sequencing data used in our experiments cannot be sufficient for whole-genome assembly, but it enables representative sampling of elements present in a genome in multiple copies.

Furthermore, we tested the effect of two factors when presenting the masks: (1) the spatial pattern of the noise mask could be either "identical" to or "different" (i.e., composed of a new stochastic sample of elements) from the comparison and test stimuli, and (2) the contrast of the masks could be either lower than, the same as (on average), or higher than the comparison and test stimuli.

In 1926, an Italian and an American group claimed to have isolated a sample of element 61; both "discoveries" were soon proven to be false.

If you're looking to mock up an iPhone app during the design or coding process, a good place to start is the fully editable PSD file on teehan+lax that includes samples of most elements.

The particle accelerators fired beams of lighter nuclei at samples of heavy elements, smashing the atoms together until some of them fused.
