At the second stage from each selected area (primary sampling unit) the sample of secondary units (households) was selected.
Times are expressed in UT of the respective days and in units of sample (1 sample = 3 s).
(a) STM topography image of 16-unit cell sample of La5/8Ca3/8MnO3 grown on (001) SrTiO3.
Due to required rinses of the unit sample lines, a portion of the sample is lost and must be accounted for when calculating final analyte concentrations.
We aimed to collect data in every NHS trust in England providing home birth services, every freestanding midwifery unit, every alongside midwifery unit, and a random sample of obstetric units, stratified by unit size and geographical region.
Vice squad units bought samples of bath salts for testing, but the results came back negative; they contained no illegal substances.
Within these units, random samples of individuals, stratified by 10-year age group, were drawn from local population registers.
Similar to the underlying unit, bulk samples of the entire unit contain high amounts of brackish foraminifers and ostracods, but also scattered fragments of corals, mollusc shells, bryozoans and echinoderms.
Despite the leverage analysis showing that their results were not due to data from one specific unit, given the relatively small sample of units in the study, the possibility of a group of units biasing these results still exists.
A field test of the approach enabled us to detect 130 molecular operational taxonomic units in a sample of 252 juvenile trees.
The aim of this study was to explore perceptions of barriers to screening for IPV on postpartum units in a sample of Canadian nurses.
