CASE STUDIES:

Characterization of Fine Particles from Machining in Automotive Plants
Jean Dasch, James D'Arcy, Aaron Gundrum, John Sutherland, John Johnson and David Carlson

1. How does the particle size using water based fluids compare to
    that with straight oils?

a. No change
b. Larger particles due to lower viscosity
c. Smaller particles due to evaporation of water
2. The particle size near new technology machining processes is
    shifted to smaller particle sizes due to large particle removal by
    the enclosure. True or False?
True
False
The Effect of Subject Characteristics and Respirator Features on Respirator Fit
Ziqing Zhuang, Christopher C. Coffey and Roland Berry Ann

3. Respirator models with only one size (i.e., one-size-fits-all) can fit all
    respirator wearers. True or False?

True
False
4. Research results indicate dimensions other than those currently
    used for half-mask respirators may be more appropriate to define
    test panels whose fit is intended to be representative of worker
    populations. True or False?
True
False
Predicting Historical Dust and Wood Dust Exposure in Sawmills: Model Development and Validation
M.C. Friesen, H.W. Davies, K. Teschke, S. Marion and P.A. Demers

5. Gravimetric measurement methods used to measure wood dust
    levels only capture wood dust. True or False?

True
False
6. Adjustment factors to convert dust levels to wood dust levels
    were based on:
a. the proportion of time spent near each dust
          source.
b. the proportion of abietic acid in the inhalable
          particulate by dust source.
c. the proportion of respirable particulate to inhalable
          particulate by dust source.
Assessment of Fungal Growth on Sodium Polyborate-Treated Cellulose Insulation
José Herrera

7. Over the span of 124 days, cellulose insulation treated with sodium
    polyborate is susceptible to fungal infection. True or False?

True
False
8. Different formulations of sodium polyborate treated cellulose
    insulation were infected with statistically equal percentages
    of fungal infection. True or False?
True
False
Use of Green Fluorescent Protein-Expressing Aspergillus Fumigatus Conidia to Validate Quantitative PCR Analysis of Air Samples Collected on Filters
James J. McDevitt, Peter S.J. Lees, William G. Merz and Kellogg J. Schwab

9. The use of __________ expressing Aspergillus fumigatus conidia
    allowed for expedient and accurate counting of conidia when
    compared to wild type conidia.

a. Antibody
b. Green fluorescent protein
c. Cytokine
d. Antigen
10. What is measured during qPCR amplification of Aspergillus
     fumigatus conidia?
a. DNA
b. RNA
c. Protein
d. Antibody
