Biospecimen yields were measured according to the number of aliquots of plasma, buffy coat and red cells in each preservative type, and compared with pre-specified targets for each of these biospecimens and also compared between the different collection sites, using standard t-tests.
For summary information about the different collections, please see our corporate collections, personal collections and collections in focus pages.
Because of the small amounts of serum used and the different collection methods, we can not compare the serology results between groups, except to confirm that all seroconverted.
This disparity calls for the creation of protocols of data collection, in order to homogenize existing dataset and increase the possibility of comparisons between the different data collections.
In PMWS-affected pigs in the Danish field study, a peak in IgM antibodies was not detected probably because time intervals between the different blood collections were too long (3 weeks).
The purpose of this study was to use mitochondrial cytochrome oxidase I (mtCO1) to assess the genetic relationships between different collections of D. citri from around the world.
With a tetrapolar mating system, frequency of interfertility among haploid isolates from the same fruitbody should approximate to 25%% for Armillaria species, and between different collections of the same species should be much greater.
The comparison between average values of gene diversity for each loci between different collections was carried out using the Student's t test, Wilcoxon's signed-rank test, and a Bayesian approach implemented to the R platform (algorithm TEST_h_DIFF, available at http://www.ucl.ac.uk/tcga/software/index.html) [ 33].
For the cross comparison analysis between different collections we have different technologies, such as aggregation framework [100], MapReduce [101, 102], Hadoop [14, 19] etc.
To avoid the build up of phage to a given starter culture or mix of starter cultures, many factories rotate between different collections of starter organisms, but the precise utilization of starters is commercial and kept in confidence.
