For example, for the cheese and crackers, for which we displayed a portion size of 30 and 25 g of cheese and crackers respectively, the cheese corresponded to 0.75 of the reference amount (40 g) and the crackers corresponded to 0.76 of the reference amount (33 g), so the total reference portion for this food was (0.75 + 0.76)/2, or 0.75.
For analysis of extracellular (secreted) metabolites in particular, essentially no manipulation of the sample is required aside from addition of a small amount of reference solvent containing D2O for locking the spectrometer and DSS-d6 for referencing the spectra.
Written with the help of Mary Gotschall, a financial journalist, it includes a fair amount of reference material like telephone numbers for various agencies and anodyne tips like "always write out a check in ink" or "if anyone says you can receive a high return without risk, be suspicious".
Both patterns provide the same amount of reference block data for the same SR ± R.
Systems for FR in video surveillance are typically designed a priori with a limited amount of reference target data and prior knowledge of underlying class distributions.
A standard curve was generated by non-linear regression (MMF model, each r>0.99) of plots of optical density values versus the amount of reference sample protein.
Future work will include interface improvements of the web-based version (additional visualizations and filter options) and non-redundant databases to account for the increasing amount of reference genomes containing only a small fraction of new sequence data.
We labeled 12.5 ng amplified RNA with biotin and the same amount of reference RNA with fluorescein.
In order to investigate whether the amount of reference organisms have influence on the performance of ION, some experiments are carried out.
Using the ratio of the two isotopologue peak areas and the amount of reference standard, absolute quantification of the natural isotopologue in the sample can be achieved.
The amount of reference material is such that the isotope ratio in sample and calibration blends "exactly" match in this double IDMS approach.
