The grant will support an international initiative to establish a global and cross-disciplinary system for the registration and globally unique identification of physical samples used in scientific research so that they can be located for re-use, cited, and linked to data and publications to make scientific results more reproducible.
The physical sampling used in the confocal Raman measurement precludes the acquisition of a meaningful micrograph from the same sample; however to allow for comparison, confocal Raman spectra were acquired from a similar pigskin biopsy using approximately the same dimensions.
It said that after reviewing the test results, Halliburton "destroyed records of the testing as well as the physical cement samples used in the testing".
They conducted their study on two samples; modern Swiss and historic European samples using physical osteological examination (POE).
Electronic transport measurements were performed on multiple samples, using the physical property measurement system (PPMS, Quantum Design, San Diego, CA, USA) with a fixed excitation current of 0.01 mA; the temperature varied from 5 to 340 K.

Similarly, to assess the influence of the sample preparation on the gene expression profile, we compared the HepG2 transcriptomes obtained from the same physical sample prepared using two protocols: method M (dataset HR_m) and method C (dataset HR_c).

Samples used for the physical characterization of the micelles were prepared exactly the same way as described above but using non-radioactive indium chloride.
In 1998 2000, all surviving subjects, now aged 60 79 years, were invited to attend a physical examination and provide fasting blood samples used to measure metabolic parameters (5).
The physical properties for the two dead oil samples used in this study are given in Table 2.
