The particular advantage of neutron diffraction is that neutrons penetrate deep inside a sample and therefore probes structural changes inside the bulk of a material.
However, one of the most interesting features of the presented battery is that the power it delivers is proportional to the conductivity of the liquid sample, and therefore, it can be operated as a self-powered sensor (Fig. 2e).
Harris said, "This online survey is not based on a probability sample and therefore no estimate of theoretical sampling error can be calculated".
No Pygmy ancestry was detected in either sample of Yoruba individuals (Supplementary Table 1), indicating that the Yoruba and YRI samples are not adequate proxies of African ancestry in the ASW sample and therefore possibly inadequate for other samples of African Americans.
Hardness testing with Knoop and Vickers indentations overcame some of these limitations, but they prohibited the retrieval and retesting of the sample and therefore the testing was restricted to one area or section of the tooth.
This mode allows a shift in fraction nonconforming, p, to occur at any time during the inspection of a sample and, therefore, provides more realistic results than the zero-state mode.
That's a tiny sample, and therefore, the survey findings should be interpreted with extreme caution.
402 respondents is a tiny sample, and therefore the survey findings should be interpreted with extreme caution.
The under-11s account for two thirds of the sample and therefore two thirds of the cases of child labour.
Such benthic organisms are harder to visit or sample and therefore study, says Sönke Johnsen, a marine biologist at Duke University in Durham, North Carolina.
Hydrolysis is complicated if there are proteins or polyphenols in the gum sample, and therefore interaction with the reducing sugars may take place.
