General suggestions:

The annotated file is attached with suggestions, modifications, and errors.
In general, the work is correctly executed and presented, but the Discussion and Conclusions sections should be rewritten, focusing on the data of own observations, avoiding speculation on parameters or measurements not determined in this essay and avoiding using other references except in the case that really help explain your own data.

The manuscript has been revised entirely according to the given suggestions, including discussion and conclusion sections. All unnecessary references and statements have been deleted.
