4. 1.2.8. 1 Preliminary Data Tabulation, Collection and Analysis 
All data referred to in this section are listed in tabulated and graphical form in appendix I. 
In this experiment, data were collected three times during the photophase and three times during 
the scotophase every day, and this data is reported in appendix I: section 3.4.1 under raw data for 
test 1 and test 2. The averages of the three data points taken in the photophase and the scotophase 
each day are reported in appendix I: section 3.4 under individual calorimeter data for NH3, CO2, 
and O2 concentration for test 1 and test 2. The mass generation rates were calculated based on 
these data. 
The relative humidity sensors in each of the calorimeters and chamber sensed relative humidity 
every five minutes over the 10 hr test period each day and values are reported in appendix I: 
section 3.4 under relative humidity data for test 1 and test 2. The average values of relative 
humidity and temperature in the calorimeters and chamber over the 10-hour test period were 
used to determine the humidity ratio value of the air (g moisture /kg dry air) from a 
psychrometric chart. This data were used along with data on water added by the humidification 
system and water removed by the dehumidification system to calculate water production rates 
which are reported in the appendix I: section 3.4 under water production data for test 1 and test 2. 
The individual weight of mice, feed, water, and litter were determined every day of the tests and 
reported in appendix I: section 3.4 under raw weight data for test 1 and test 2. Mice weight in 
individual cages and cage group were calculated and reported in the appendix I: section 3.4 
under mice weight for test 1 and test 2.
