On average, pregnancies lasted 38 weeks from the day of conception to the day the baby was born, or about 40 to 41 weeks from the day of the women's last menstrual period. (The latter measure is more commonly used to determine a woman's due date.).
The act of copying or adapting someone elseâs work is a restricted act. Any adaptation will be legally regarded as a derived work; so if you simply adapt the work of others, it will still be their work, and they have every right to object you if publish such a work when they have not given you permission to do so.
In copyright law, a derivative work is an expressive creation that includes major copyright-protected elements of an original, previously created first work (the underlying work). The derivative work becomes a second, separate work independent in form from the first. The transformation, modification or adaptation of the work must be substantial and bear its author's personality to be original and thus protected by copyright.
