Applicant's summary and conclusion

Conclusions:
About 12% of the particles had a mean width of 10.42 µm and a mean length of 15.32 µm and about 50% of the particles showed a mean width and length in the range from 0 to 63 µm.
Executive summary:

The particle size distribution was determined via light microscopy and using a image data processing software. About 12% of the particles had a mean width of 10.42 µm and a mean length of 15.32 µm and about 50% of the particles showed a mean width and length in the range from 0 to 63 µm.
