This paper was written by a non-English speaker. Most of the descriptive terms in the paper are used improperly. For instance, in the writing, it says that the use of the atomic bombs saved several lives, using the word several instead of a different more fitting word can only come from poor translation from the writers, mother tongue to English.
This paper is complete $#*! and totally unusable. I can't believe LinkedIn would recommend this service. Absolute crap.
