Fig. 8 Sketch of pressurized container with variable volume.
The air flow rate was controlled separately for each container by variable area flow meters (Westphal, Ottobrunn, Germany).
CellInfo (the physiomimetic parametric container) contains an accessor for a variable that maps to the resources (e.g. O2) made available to the cell.
Clearly, the independent variable "container type" could influence the dependent variable "sales". Container type is a qualitative variable, however, and must be assigned numerical values if it is to be used in a regression study.
(ii) The variable container leakage (none vs. ≥ 1) was compared by presence of unlabelled containers, staff qualification, firm registration status, requirements and town location.
Clearly, the independent variable "container type" could influence the dependent variable "sales".
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.
The variable container disposal practice (safe vs. unsafe) was compared by firm registration status, standard safety requirements, staff qualification and town location.
Cross-tabulations using firms as the units were conducted to identify associations with hygiene practices as follows:> (i) The variable container disposal practice (safe vs. unsafe) was compared by firm registration status, standard safety requirements, staff qualification and town location.
Each container contained two capsules.
