Most available data on quantities and characteristics of buoyant ocean plastic are derived from samples collected with small sea surface trawls initially developed to collect neustonic plankton27.
On the other hand, air samples collected with SPMDs within the coke plant showed variable degrees of genotoxic and mutagenic activity.
There are no direct comparisons of blood glucose values in samples collected with barrier serum tubes (SST™) and NaF/potassium oxalate (NaF/KOx) plasma tubes.
In the months leading up to the show, Yi, currently a visiting artist at M.I.T.'s Center for Art, Science, and Technology, invited a hundred women she knows professionally artists, writers, art historians, curators, dealers to provide her with samples, collected with cotton swabs.
This is demonstrated for synchrotron radiation X-ray fluorescence spectrometry (SR-XRF) of aerosol samples collected with a rotating drum impactor (RDI) in hourly intervals and three particle size ranges.
Samples collected using the new IMPROVE NHx sampling system were evaluated against samples collected with a collocated URG annular denuder/filter-pack module for 6 weeks; the observed bias was −7%.
The activities of the luciferase were measured in total protein extracts from triplicate samples (collected with a 5 mm leaf puncher with same number of leaf discs in each sample) using Berthold Centro LB960 luminometer with the luciferase assay system following the manufacturer's instruction (Promega).
In this paper we describe the development and validation of an analytical method to analyze 32 prescription and illicit PADs (amphetamines, benzodiazepines, cocaine, cannabis, opioids, ketamine and m-CPP) and metabolites in oral fluid samples collected with a Quantisal™ device.
Selectivity curves for pikeperch and bream were calculated based on samples collected with gear fitted with protective sieves accompanied by an additional net sewn to the outside of the sieve to retain all the fish that passed through the fyke-nets.
In the months leading up to the show, Yi, currently a visiting artist at M.I.T.'s Center for Art, Science, and Technology, invited a hundred women she knows professionally — artists, writers, art historians, curators, dealers — to provide her with samples, collected with cotton swabs.
Wet samples and samples collected with plants and snow (see Table 1) required this preparation step.
