In two recent studies, two-photon fluorescence (TPF) microscopy was employed on samples of intact colon mucosa [ 29, 30], demonstrating that the technique can be used for a label-free microscopic evaluation of tissue morphology.
In particular, liquid-state 1H, 13C and 31P nuclear magnetic resonance (NMR) spectroscopies were employed on milk samples supplied by a single dairy farm breeding buffaloes fed by conventionally and biologically fodder (CFM and BFM, respectively) during a 2-year-long experimentation.
Further, different material characterization techniques were employed on the pre- and post-burnt samples to understand the chemical and morphological changes and interlink that with overall burning characteristics.
For developing the index, exploratory factor analysis approach has been employed on the sample of 1201 responses collected from the residents of 12 different cities in India.
For the remainder, the Aware™ BED™ EIA HIV-1 Incidence Test (BED test) (Calypte Biomedical Corporation, Portland, Oregon) was employed on a sample taken within 3 months of diagnosis, according to the manufacturer's instructions.
A number of proxies are under development, but some of the most promising (e.g. palaeoseawater records of Li and Nd isotope change) can only be employed on such large samples of mono-specific foraminifera that application to the deep sea sediment core archive becomes highly problematic.
At the time of the survey, approximately one-half of the entire OFS sample was employed on a full- or part-time basis (44.4 and 6.0%, respectively).
Specific duplex polymerase chain reaction (PCR) was employed on 411 (386 cattle and 25 buffaloes) blood samples of dairy animals from 9 districts of Punjab, India, for simultaneous detection of Babesia bigemina and Trypanosoma evansi.
An empirical Bayes "shrinkage" method was employed on the standard errors to improve power for small sample sizes [81].
A convenience sampling methodology was employed for sample selection.
