Part of the problem, they said, is that the sample of known terrorists and actual attacks is so small that it is difficult to establish patterns of suspicious behavior.
Therefore, this data set provides a large and diverse sample of known and potential bioactive chemical space.
– have been used as a measure for the relative polytetrafluoroethylene (PTFE) content of surfaces and could be quantified by calibrating with sample of known composition.
Colombo et al. [30] used quantitative 13C nuclear magnetic resonance spectroscopy (qNMR) for the quantification of fructose and ethanol in wines using as an external reference the 13C qNMR spectrum of a sample of known concentration.
The geometry of human RF coils will make it possible to insert a bone sample of known μ inside the 31P coil so that 31P signal can be directly converted into μ31P by comparing the signal of the skull with the signal of the sample in the same image.
One standard sample of known AOC and one blank sample (5 µL of distilled water) were also processed to be used as a control reference.
