The paper "Steady-State Transitions and Polymorph Transformations in Continuous Precipitation of Calcium Carbonate ", published in September 1994
Industrial & Engineering Chemistry Research 33(9) where Debasish Chakraborty is the First author instead of Debapratim Chakraborty. You can check the original publication and rectify the name of the first author.
This is a frequent problem in ResearchGate in case of similar names. See "A researcher has wrongly claimed co-authorship of my publication" in https://explore.researchgate.net/display/support/Authorship for instructions how to correct this. But unlike this help page suggests, most probably it was not the other author himself who wrongly claimed authorship, but ResearchGate's automatic algorithm wrongly identified him as the co-author and assigned your publication to his profile.
I was going through Research Gate's home page and help. There is copyright heading which covers the way to claim your authorship and rectify a mistake. I agree this may be a gross mistake from algorithm or intentional. I am the first author of this publication and someone's name is appearing. Does it fall under copyright infringement ?
