C. siphonella (Levi, 1965) showed as a cluster of vertical tubes from a common base.
To estimate the likelihood ratio for model comparison adjusting for the clustering effect of tube well (household using the same well), we fitted a random effect logistic regression model using tube well id as the random effect variable.
(Or since: the Sears Tower, in Chicago, which replaced the World Trade towers as the world's tallest building in 1973, is also a tube building, but it is actually a cluster of nine smaller tubes).
(Or since: the Sears Tower, in Chicago, which replaced the World Trade towers as the world's tallest building in 1973, is also a tube building, but it is actually a cluster of nine smaller tubes). The Twin Towers would be perforated steel boxes surrounding a hollow steel core.
For phage rescue prior to ELISA analysis, 40 μl of master stock is transferred from each master to another set of cluster tubes containing 400 μl of 2x YT-AG (ampicillin and glucose) and helper phage (final concentration of 5 × 10/ml).
The 'core' is a cluster of easily removable, tube-like PEM fuel cell units with integrated current collection and heat-exchange.
The altitude is not significantly different between clusters, whereas depth of tube wells is significantly different between clusters.
The initial layout comprised two parallel complexes approximately 1000 m apart, each with five drifts which were to hold a stacked cluster of five HDP gun tubes, for a total of 25 guns.
The effects on lymphatic tube formation including the capillary-like structures, the total number of cell clusters and branching of tube formation (i.e., capillary-tube number) of each group were observed using an inverted phase-contrast light microscope (Olympus IX70) as described previously [ 23].
