Since L. terrestris is known to bury seeds irrespective of size and shape [12], [19], nine seed dummies (little glass beads; diameter 2 mm) spaced 25 cm were deployed in each earthworm treatment (control, earthworm addition, and earthworm reduction).
Egg recognition activity can be tested by a simple bioassay using dummy eggs made of glass beads (Fig. 1B).
Half the amount of each natural extract was applied on each dummy with a Hamilton glass syringe (100 μL) for each behavioural bioassay, whereas the second half was saved for chemical analyses.
To simulate the actual condition of the falling film evaporator, the passages of liquid/vapor flows are constructed using quartz glass panels and dummy tubes.
Here Ms. Semmel seems less interested in the dummies themselves than in the glass that separates them from the outside world, but which also undermines, through the play of reflections, the viewer's ability to identify inside and outside.
As Jesse Stay, the author of Google+ For Dummies and Google+ Marketing For Dummies, notes on his blog, a number of Glass Explorers are reporting that they have received notifications about this package through their My UPS accounts today.
To simulate the practical condition in a falling film evaporator, the flow passages of the liquid/vapor are constructed using two quartz glass sheets and two columns of dummy half tubes.
Dummy eggs were made of 0.5-mm diameter glass beads and were coated with each test chemical.
First, the gender dummy coefficient is increasing with quantiles for each year (glass-ceiling effect).
If the beverage could be placed in glass bottles, plastic bottles, or cans, it would require two dummy variables to properly represent the qualitative variable container type.
