Sentence examples for intermediate isotopes from inspiring English sources

In one case, intermediate isotopes in the uranium or thorium decay chain can become isolated in certain minerals due to differences in chemical properties and, once fixed, can decay to new isotopes, providing a measure of the time elapsed since they were isolated.

Because initial minor actinide isotopes are typically not fissionable by thermal neutrons the idea is to fission instead the intermediate isotopes generated by the first neutron capture.

We treated HeLa cells either with 5-azacytidine or with DMSO or 5-aza-2′-deoxycytidine as negative controls for 18 h and labeled proteomic lysates with dimethyl light or intermediate isotopes before subjecting the samples to mass spectrometry (Fig 7A).

In the case of Lake Nakuru, even a mixed rotifer sample would have led to intermediate isotopic values (δN: 9.2‰; δ C: −17.2‰) and to substantially different outputs from isotope mixing models.

A reverse-labeling experiment was also performed in the internal standards with intermediate stable isotope dimethyl labeling and the islet tryptic peptides sample with light stable isotope dimethyl labeling.

A series of different amounts of light stable isotope dimethyl-labeled synthetic peptides mixture were used as internal standards, and incorporated into the intermediate stable isotope dimethyl-labeled islet tryptic peptides sample.

All the three families present an intermediate radon isotope which, due to the noble gas properties, can be easily remobilized from the mineral matrices where it is produced by radioactive decay.

To generate tracer-specific isotopic enrichment patterns of metabolic intermediates, stable isotope-labeling experiments have to be performed using the tracer of interest (Fig. 1).

A method to produce relatively high concentrations of intermediate components from isotope mixtures in a separation cascade with local extension of a working substance flow at its inner stages is demonstrated.

Hickey-Vargas et al. (2008) analyzed the two gabbros and concluded that they have an Indian MORB Hf-Nd isotopic signature, with Pb isotope ratios intermediate but closer to Pacific MORBs than the WPB, which has a strong Indian Pb isotope signature.

Due to the mass difference between the light and intermediate or heavy stable isotope-labeled peptides, the peak intensity (peak height or peak area) ratio can be obtained by MRM-MS.
